Background

A portable probably started with a cave man carrying a burning stick of wood.  There have been many portable based on burning something.  Once the became available flashlights became more popular than they were when a lead acid or other was needed.
This web page is being done by adding a section after reading something on the internet, either an eBay item or reference material.  Once an inventor name shows up then his inventions are grouped or the company the invention is assigned to has a group of related products.
I have included on this page what most people would consider a flashlight, but also any light that uses the for it's power.  Also some fixed battery powered lights like used on barricades or in purses, &etc. that are battery powered.  And some closley related patents like anti reflection coatings or earlier lights.
Not on the page are patents related to Flashlights as used on cameras.
Also see my web page for lights that work with fire and/or the web page.

Components

The key components of a portable are: Source of power, A way to start and stop the light source, A way to convert the power into light ,A way to control the light.  For a flashlight these would be: , switch (aka circuit closer), lamp with a filament, reflector and/or lens.

Lamps

The early Flash Lights used an Edison type minature screw base lamp very much like the # 14.  A problem with this lamp is that the filament location is not controlled.  Part of the reason for that is there is no reference surface on the base to support good filament location.
The single contact miniature flange base used the flange surface as the reference plane for locating the filament and so allows flashlight reflectors to be designed that have the filament at focus without any adjustments.
The 222 miniature screw base Lamp has a built in lens and so does not need to be in a flanged base.
There seems to be a disconnect between the battery makers and the lamp makers.  The Leclanche type dry cells used have a nominal voltage when fresh of 1.5 volts so two in series would be 3.0 volts.  The end of life voltage is taken as 0.9 or 1.0 so two in series would be 1.8 or 2.0 volts.  The lamp voltages seem to be about half way.  The 1915 patent 1163887 (see below) by Charles Burgess mentions this and his lantern has a two position switch so that a resistor can be inserted for the first few hours of operation and then the direct connection made for the remainder of the battery life.  It's my feeling he was correct, running the Pocket Flash Lights on a full 3.0 volts from a modern battery that's "stiff" will greatly shorten the life, if not just burn it out.

Lamp Test E10

Test Stand for E10 Base Lamps
This is a test stand I built to allow measuring the Voltage and Current of E10 based lamps.  The Victor X solid lamp is in the stand for the photo.  When it's on and you are looking at a side view like this there is not much light coming out, almost all the light is aimed in the narrow beam like for the 222.
The wood came from Michaels 85753336002 for 60¢.  The expensive part was getting good wood bits.  The brass hardware is from the battery adapter and the wire is from the which is 16 AWG solid copper, much larger than needed to light the bulb, but good for measuring the resistance of cold lamps.

Filaments

Eveready Mazda 1.5 Volt

Eveready Mazda 1.5 Volt filamentThis appears to be a single strand, not a coil so maybe a carbon filament rather than the more modern Tungsten type.
Q quick check of three os the flattened bulb type lamps showed they all had this type of "S" filament.
I'm fairly certain that all the other lamps have coiled Tungsten filaments.

Lamp is rated for 5 hours at 2.25 Volts @ 0.25 Amps. After measuring the I-V curve from 0 to 215 ma and ploting in Excel shows the first few points coming up from zero to be off the straight line you get afterwards, so eliminating them and plotting from 125 to 215 ma gives this straight line:
I(ma) = 67.259V + 104.9 with a fit of R2 = 0.9982
solving for 2.25 volts gives I(ma) = 256 ma, matching the published data pretty well.
solving for 3.0 volts gives I(ma) = 307 ma  Would that burn out the bulb???
Testing a PR4 lamp rated 2.33 V @ 270 ma shows it's very close 2.4 V @ 271 ma.  When the voltage gets to 3.7 the current starts to decrease with time, like the resistance is going up with time which might happen is the filament is starting to boil away.
Although given for currents close to the rated current these relationships give a feel for how incandescent lamps work.
Light V^3.4      Power V^1.6      Life 1/V^16      Color V^0.42
Because of the boiling temperature of tungsten the best possible efficiency is about 52 lumens/watt.
If a lamp is rated for 5 hours of life when operated at it's rated voltage it will burn out much earlier if operated at higher voltage.  For example the GE 223 life might be described as:
Life = 2157200 / (V^16), so when V=2.25 Volts Life = 5 hr BUT at 3.0 Volts Life = 3 Minutes!  One factor that may have allowed a longer bulb life in the old falsh lights is the internal resistance of the battery and flash light.  An Ohm or two of resistance would bring the lamp voltage down to the spec for a battery with an open circuit voltage of 3.0 volts.

Edison 10 mm Miniature Screw Lamp Base (E10)

Based on measuring one I think the thread is 14 TPI with a pitch diameter of 0.35 inches.  Those numbers are "nicer" than the metric equivalent 1.75mm pitch and 8.82 mm pitch diameter.  what it really is.  I'm guessing the 10 mm came from  the fact that these lamps were being made and sold in many countries, not just the U.S.A. and metric was used in more locations.

Preserving Lamps

With the advent of LED based flashlights the filament type are going obsolete.  Today most stores carry spare lamps I think in not too many years they will be harder to get and more expensive.  Even today there are flashlight lamps that are fairly hard to come by.  But being able to use the flashlight is a large part of it's appeal.
The problem is that lamps are typically specified to operate at a voltage about half way between a fresh Carbon Zinc battery (1.5 Volts) and a dead one (1.0 Volts) or 1.25 volts per cell.  You can see that in .  But running a lamp above it's rated voltage.  Note that a nominal lamp life is 15 hours at rated voltage.
Using modern Alkaline cells causes the lamps to burn brightly but not for very long.  Using Ni-MH rechargeable cells drops the voltage from 3.0 V for fresh alkaline to about 2.8 V for fresh Ni-MH but they soon drop to 1.2 to 1.3 V per cell or 2.4 to 2.6 Volts which is very close to the specified operating point.  So that's a rather simple way to preserve the lamp.
A better way is to use a current regulator to limit the current rather than regulate the voltage.  With current regulation any resistance in the flashlight makes no difference to the lamp.  With voltage regulation any resistance will make a big difference to the lamp.   I like this approach a lot.  It would allow adjusting the current so you could make the trade between brightness and lamp life.

Repairing Loose Bulbs

Loctite 290 Penetrating Thread Locker
Quite a number of times the bulb has become unstuck to the base and is being held just by the two wires.  If you apply any torque the wires will snap right were they enter the glass bulb and the lamp will be ruined. I can remember these seperated bulbs going back over 50 years.
The fix is to apply (, )to the crack between the bulb and base.  It's designed to lock threads that are already mated.  This is a penetrating liquid and is very thin.  After cutting off the tip of the small tube the first time I used it way way more came out than I expected.  So be very careful not to waste this expensive liquid.
The strength is best when the gap it's filling is smallest so I used a rubber jaw wood clamp to hold the bulb into the base and let it sit for more than 3 days (72 hour cure time).  If repairing a lamp while it's still in a light be very careful that no thread locker gets on the base threads.
Available at Napa auto parts in 0.20 fluid ounce (6 ml)  tube.
When a keychain UV LED is used to illuminate the bulb the Loctite 290 appears as a yellowish color where it's between the glass and base.

112 and 222 Lens Type TL-3 or GTL-3 Bulb

These are Edison miniature screw (E10) based lamps with a built in lens.  Typically used in penlights.  Since the lens to filament relationship is what's critical there is no need for a flange to locate the lamp with respect to the flashlight like in the PR- series of pre focused lamps.  The support wires for the filament don't stop at the filament like on earlier lamps but instead continue upwards to a reference location.  When the glass assembly with the filament is inserted into the bulb it stops when the top of the support wires hit the inside of the bulb at which point the glass is fused.  This located the filament allowing for focus.

Note : these were Zinc Carbon cells.  Alkaline cells are about the same size, BUT are made very differently.  For example the top (positive) terminal on a Zinc Carbon cell was just the small  cap on the carbon and the Zinc can was the negative terminal.  An Alkaline cell has all of the top terminal and the cylinder all connected to positive and an island at the bottom is the negative terminal.
Note 2:  The energy in a cell is to a first order approximation proportional to it's volume.  A second order approximation would subtract some constant so as the total volume decreases the useable volume decreases even faster.

Ohio No. 32 Flash Light Battery 3 Volt


This Flash Light battery is 2 5/8" x 1 3/8" x  3/4".  Note 3/4" is just the size to fit the Eveready Pocket Flash Lights.  The 1 3/8" dimension, the width in the photo would be just right for the narrow Pocket F.L..  That leaves the 2 5/8" height which would be too tall.  2 1/2" is also too tall.  2 1/4 or 2 1/8 high would work.


It may be that these very early batteries had a lot of internal resistance, so although they measured 3 volts open circuit, when connected to the lamp the actual voltage across the lamp was less than 3.0 volts.  I feel that connecting two modern 3 volt Alkaline cells to the lamp would burn it out.


Eveready Clamshell Pocket Flash Light w/ No. 750 Battery Installed
This Eveready Pocket Flash Light has a No. 750 battery installed.
The 750 is a three cell battery with dimensions of 2  5/16 x 1  11/32 x 1?
You can see at the top left of the battery the short tab is making contact with the tab connected to the switch.  That makes a circuit to the case which in turn is connected to the threaded part of the lamp.  The tip of the lamp makes contact to the long battery tab that's folded flat across the top of the battery.  So as shown the light would be on.
But the switch is shown in the up position which should be off, so either the switch tab or battery tab would need to be bent so they are not touching when the switch is all the way up.
The U shape metal that's part of the switch is there to hold the battery to the right.

The switch is a little below the half way point and the circuit is open.  If the switch is pushed up the circuit will be closed.
It looks like red sealing wax has been poured into the top of the battery and there's still an eighth of an inch of battery wrapper exposed.  For a battery that's probably 90 years old it's held up fairly well.

Two AA Battery Adapter to replace No. 750

Two AA Battery Adapter for No. 751 Pocket Flash Light Battery
This was the first try at making battery adapter patterned after the one by Bill Utley in the Flashlight Collectors Newsletter.  But instead of using a huge pop rivet I'm using an eyelet.  But a problem showed up after the first phosphor bronze spring was attached.   It's that there is nothing to keep it from turning, as shown in the image to the left.  The real batteries have both tabs well located in rotation.  Now working on a way to fix the tabs rotation.

This is the second try.  Each of the phosphor bronze spring straps is anchored in two places so they can not rotote.  All three of these pocket flash lights works by just moving the battery adapter from one to the other without any tweaking of the starps.
The fit is snug but the bottom door on the eveready dec 17 1912 unit (lower left conrner) stays closed.

The tabs are made out of a dead soft metal and do NOT have spring action and so do not make good contact with the lamp base.

Optics

The light leaves the bulb in all directions.  Some may go to the reflector and where it goes next depends on if the filament is at the reflector focus.  Some light will never touch the reflector and instead goes out the end of the device.  If there's a lens then if the filament is at the focal point of the lens that light will be collimated, i.e. it will go in a parallel bundle of light.  The very common Edison 10 mm miniature screw based  (E10) lamps do not control the location of the filament and so are almost never focused as installed.  That's why there are many patents on ways to focus the light.
The very early flash lights used white paint on a parabolic reflector.  Later some used silver reflectors, these look great when silver polish is used.  Later some shiny metal (Chrome, Nickel ?) was plated on a brass reflector.  Still later metal was applied to plastic to make the reflector.
In the case of a flashlight with a reflector and flat glass or the case of the reflector and lens the light that goes froward from the lamp makes a wide beam and the light that's reflected then goes forward makes a narrow beam.  In some cases, like in smoke or fog, it's good to eliminate the wide beam which is weaker than the narrow beam so that back scattered light is reduced thus increasing visibility.  The does this.  There are other flashlights that get a similar, but not as good, effect by blocking some of the forward light with an obstruction directly in front of the lamp.  For example the Smoke Cutter made by G.T. Price.
There's a good explanation of the dual lens optical system in a patent for an allergy pollen sensor.

Source Geometry

Some common light sources, in sort of chronological order, are hot filaments in screw based then in flange type light bulbs, various types of electrical arcs and now s.  All of these can be put into an optical integrating sphere () and measure the total light output in all directions in Lumens () just as Edison did with his light bulbs.  But the lumen output of a flashlight is not the key parameter.  More important is the light reflected by a distant object that you want to illuminate measured in units of Candle Power () Candela () or Lux () also see luminous flux (), Luminous efficacy (300 lumens/watt max for an LED) () and the .

The light you see reflected from a distant object depends on a number of factors such as: how much light the source produces (measured in an integrating sphere and in units of Lumens), the optics that shape the light into a beam, the atmosphere between the light source and the object and you eye, how the object reflects.

Looking at the t flashlights:  they have flat glass lenses and if you turn the flashlight away from pointing at  your eye at some angle (30 to 45 deg) the LED can no longer be seen, so inside that solid angle there is no optical modification of the light output, i.e. it's the same output that you would get without a reflector or lens of any kind.  From that angle to a little less than 90 deg from the beam centerline the reflector is supposed to make a beam.  So when you shine the light on a wall you will see a large circle of light determined by the direct LED light and a brighter center spot determined by the reflector.

When an HID source is used, like in the   it's a small cylinder of light allowing for a more efficient optical system.  So with more efficient optics you can get a brighter light then with a similar Lumen output LED light.

In the case of old fashioned flashlights using screw based lamps, the uses a 2 lens optical system to produce a more defined beam than the bull's eye and reflector only flashlights of the time.

I tried to use the LM631A light meter where the flashlight and light meter were both being held in my hands, but the light is way too bright for that to work.  What's needed is an outdoor test range setup so that the light does not fall on the house and is above ground maybe 5 feet so that a minimal amount of light is reflected off the surroundings and into the light meter.  Using baffles would be one way, but different baffels would be needed for each flashlight, so just open air is probably the best alternative.  There needs to be a permanent stand to hold the flashlight and a permanent  stand for the light meter so that in the future different lights can be tested under the same conditions.  On my To Do list.

Light

There are a number of ways of measuring light.
Lumens () are a measure of all the light that a source can produce.  The measurement is made with the light source inside a reflecting sphere so that light in all directions is captured.
A Candela (Wiki - the new version of a candle power) is a measure of the visible light falling on a surface.  Note both Lumens and Candela are measures of visible light only, not IR or non visible radiation.  So these units are not applicable to IR sources.
The was designed so that it measures light with a wavelength response curve that comes very close to the human eye.
The is a modern light meter that's commonly used for testing flashlights.

Although  you might think when comparing two flashlights that the one with the highest lumen rating would be the brightest, that's not the case.  For example when the has the reflector removed and used as a base, i.e. in candle mode it's putting out the same number of lumens as another Mini Mag Light with the reflector in place, but the brightness on a nearby surface will be much less.

So the key measure is what a light meter reads at some specified distance from the light source.  This reading will depend on the product of the brightness of the source (lumens) and the ability of the optics to direct all the light in a desired direction.  The same light source may be used for area illumination or as a spot light with a very narrow beam.  The surface brightness of the spot beam will be much higher than when the same light source is used for area illumination.  This is very similar to radio antennas where the gain of the antenna comes by directing the signal in a narrow beam.

Some light sources, like High Intensity Discharge (Wiki: ) (see: ) lamps are easier to design optics for than LEDs and so can have higher surface brightness than another flashlight with a higher lumen rating, but not as efficient optics.

Switch & Wiring

Conrad's first flash lights were made using fiber tubes which are insulators.  That makes it easy to bring out two terminals which when connected turn on the light.  The big problem with that is when the switch is in the off position and any metal touches the two terminals (like in a tool box) the light is turned on and the batteries go dead.  The user later takes the light out of his tool box and the switch is clearly off, but the batteries are dead.  Seem like those batteries don't last very long.
Many early switch & wiring designs were aimed at preventing the above problem.
It's relatively easy to make a push button switch that normally off and momentarily on, the nomenclature is:  OFF-(ON).  But it's more difficult to make a switch that is positivitily off, allows momentary push button operation and has an always on position that allows you to put the light down and use  your hands for something else.
A further refinment is to place the switch somewhere so that it's very easy to use allowing full operation of the flashlight with one hand.

Care and Feeding

Often the flash light I get on eBay is very old and had rust and corrosion on some of the metal surfaces.  I don't think it's good to just leave that alone since it will continue to corrode the metal.  I have my first flashlight book on order but these lights need help so I'll present my method now.  If you know of a proven method please .
Supplies needed:

Chemicals

Chemisals for Cleaning and PreservingVM&P Naphtha or
Window cleaner fluid in squirt bottle
- -
Brasso metal polish
Kroil  made by , no substitute, 8 oz can will last forever if only used for flashlights
Rust remover, phosphate based, Renaissance Metal De-Corroder, or equivalent.
Wright's Silver polish
Renaissance Micro-Crystalline Wax Polish or equivalent high quality wax
Radio Shack Lube-Gel  2005-07-01 or . other Silicon grease would also work, especially if made under patent 5037566

Applicators & Removers

small screw driver
small fine tooth file
steel wool, No. 0000
Shop Rags, paper from box
tooth brush
tooth pick, wooden
Q-tips
tissue paper
Dust Off or compressed air
dinner plate, shallow tray, work bench, etc where the above chemicals can be used without causing a problem

Step 1 Clean and evaluate

For dust use the window cleaner and an appropriate applicator and clean.  For grease or oil residue use Varnish Makers & Painters Naphtha.  For the sticky stuff from stick on labels or paint spatter use OOPS!.

Step 2 Stabilize Rust and Corrosion

If there's raised islands of rusted metal knock them down by scraping into the island so as to not scrape the good adjacent metal using a small screwdriver or file.  Then apply the rust remover using a tooth brush and work it into the rust and corrosion areas and let it sit some time.  For very light rust that might be 5 minutes and for heavy rust for 30 minutes to longer.  An occasional reapplication of fresh rust remover and more brushing is good.  Rinse thoroughly with running water and wipe off excess water with rag and then blow dry.  Using the steel wool before and/or after using the rust remover is good.  When done you will still be able to see the spots where the rust was, but the surface will feel smooth, not gritty like when the rust is active.

Step 3 Check Function

If the flashlight is one where lamps and batteries are readily available install them and check that the light works.  When the lamp is connected to the batteries directly using wires (i.e. no part of the flashlight is being used) the brightness of the lamp should be the same as when the lamp is used in the flashlight.  If the lamp is dimmer in the flashlight then you need to clean the electrical joints.  These include:
  • the mating faces of the threads on the battery cap
  • the mating faces of the threads on the lens cap
  • the top and bottom surfaces of the battery cap spring
  • the tip of the tab on the body that points to the lamp head
  • the surface on the lamp head where the body tab makes contact
  • the mating surfaces between the reflector and the lens cap (for flashlights that do not use an insulating ring here)

Step 4 Reduce the change of future Corrosion

I have not gotten to this step yet.
Apply wax to outer surfaces and polish to help prevent future runt and corrosion.  Not sure what to do for inner surfaces and electrical parts.  Have not yet done this pending

Patent Class Numbers

Utility patents use numerical class and sub class numbers to specify the filed of the invention.  New things get invented and so new class and sub class numbers are assigned.  When new classes are assigned the classification of an older patent may change to be in line with the new numbers.  The early patents do not have any class numbers on the printed copy.
Both the Utility and Design class numbering systems are indented.  First by bold titles then by dots preceeding the numbers.
362 is the key top class number for flashlights.  The other top class numbers are in some filed related, such as electrical contacts, mechanical fastners, etc.

Conrad Hubert

Conrad Hubert (aka Akiba Horowitz ) was the owner operator of American Novelty.  He hired David Misell who was an inventor.  Conrad wanted a cylindrical light that could be put into a pants pocket.  So what we today call a flashlight is a battery powered portable light small enough to fit into a pants pocket.  If it's larger then it's called a lantern.  If it's small enough to fit into a pocket and not be obtrusive then it's called a Pocket Flash Light, aka Vest Pocket Light, Watch Pocket Light, etc.  or a Pen Light.

    Conrad Hubert signed as a witness -
    tubular flash light with bulls eye lens on end. This patent has a problem in that both switch terminals are on the outside of the flash light.  When the switch is off if any metal makes contact with both terminals the light will be turned on.  This happened a lot when the flash light was stored in a tool box where things like screwdrivers, pliers, etc. would activate the light and run down the batteries.  Even carrying one in  your pocket with metal keys would run down the battery.   Altough the patent talks about a parabolic reflector I think they were painted white and considering the diameter of the #14 screw base bulb not much light came from the reflector.  Most came through the Bulls-eye lens.
The patent also covers a gas lighter that uses the same cylindrical (the patent calls it tubular) battery and switch housing, but replaces the reflector assembly with a long stalk and an external hot wire to light gas.
The lamp, although made like others of the time, was a minature version specially made by Eveready and the patent talkes a little about it's construction.

The brand name for these Flash Lights was "ever ready".  Conrad set up a company to make the flashlight, batteries and bulbs for them.  Later the company name was changed to Ever Ready. 

A neighbor, Reed Anderson, was a partner in the Anderson Jacobson company making acoustic modems, but when Reed wanted to get into magnetic media Jacobson did not want to, so Reed started  Information Terminals Inc.  The floppy disks were branded Verbatim.  Victor Borge visited my house so Reed could show Victor what a home computer looked like and in particular his 8 inch  floppy disks.  Later they changed the company name to Verbatim.

Poor Designs

Patent 1570393
The 1570393 Flash Light drawings have had many of the notations erased to make it easier to read.
Notice the assembly consisting of spring contact 29 and disk 27 in the drawing at the left and in the photo above.  This is made as a sub assembly and then installed into the flash light by staking eyelet 28 thus attaching the sub assembly to leg 26 of the ground conductor.  You can see the leg 26 in the above photo at an angle and with the eyelet 28 still attached.  The round hole in the photo below the eyelet 28 is not shown on the patent drawings and is used for the tooling used to seat eyelet 28.
Yeildable strip conductor 32 is forced to the wall by the battery causing pressure between the tip 32' and the metal plate 31.
The problem is that when the head is screwed onto or off of the body while batteries are installed the tip 32' of the yeildable strip conductor 32 can snag on the metal surface 31 and then rotating the disk subassembly.  The only thing stopping that from happening is the sheet metal ground conductor with legs 26 and 23 which has eyelet 24 holding it to the head and eyelet 28 holding it to the disk sub assembly.  Eyelets provide minimal resistance to torque and the ground conductor 23, 26 can easily bend, as seen in the photo above.
Notice in the photo above that there's a notch in the disk edge facing the camera, but there's no corresponding dimple in the angle head to use it as a rotation stop.  The tip 32' has a square end which is bad in that the corners are points that snag the metal plate 31.  It may be that by putting a radius on the corners the strip 32 would not snag?  Yes adding a radius and smoothing the burr stops the snagging.
A jumper wire from the metal plate 31 to one of the eyelets adjacent to the lamp socket 16 completes the electrical path. 
patent 1654373 Safety Lock SwitchNow the light is on bright all the time.  The switch shown in the angle head patent is NOT used and instead the 1654373 Safety-Lock switch is used.  The switch patent also shows the strip conductor 32 which is numbered 19 and "is insulated by a coating 23 of tough, flexible material, such as celluloid, a phenolic condensation product, rubber or shellac.  The coating is shown but the notation "23" is missing from the drawing (I added it in the modified drawing here).  This coating insulates the strip conductor from a metal bracket 20  and for this flashlight has failed permanently grounding the strip conductor to bracket 20.

3 D Cell with Prefocused Lamp Eveready A National Carbon Company Product

This 3 D cell flash light uses a prefocused lamp with a flange.  These were patented by GE starting in 1934.
The parabolic reflector appears to be chrome plated unlike the silver plated reflector on the vulcanite bodied 2 D Cell Eveready Flashlight.  This light uses a flat glass lens, not the walleye lens.  When you shine the beam on a wall the image of the filament coil is easy to see.
I would expect a patent or two to cover this light dated 1930 something but have not found them.
Eveready 3 D cell Flashlight with Pre Focused Lamp The photo was taken after cleaning and steel wooling both the inside and outside.
The light came from eBay missing the lamp.  I used a radio shack 272-1158 lamp labeled KPR103 Krypton Flashlight Lamp.  And mis labeled "for "C" and "D" 2-cell flashlights".  Clearly a two cell flashlight using the highest voltage cells (Alkaline) can only produce 3.0 volts maxium, yet this lamp is rated 3.6 Volts, 800 ma, bulb type B-3½ Base: Sinble-contact minature Flange Ave Life 15 hours.  This really is a lamp for a three cell flashlight where the peak voltage with fresh alkaline cells would be 4.5 V and when they were dead of about 3.0.  Half way between those voltages is about 3.75 which is very close to the 3.6 V for this lamp. Eveready 3 D Cell Flashlight with pre focused lamp
This shows the back side of the reflector with the lamp assembly installed correctly.  There are a bunch of ways it can be installed improperly.
Although not clear in this photo, there is an insulating gasket between the reflector and the cap.  Battery negative is on the cap.  Battery negative is on the tab coming from the body when the switch is on and the battery is disconnected when the switch is off.  The tab is fixed in position, i.e. it's not a sliding tab.  The lamp center contact is always on the battery positive terminal.
Eveready 3 D Cell Flashlight Pre focused Lamp Holder
The can on the right has a leaf spring in the bottom that contacts the tip of the lamp.
The cap on the left screws onto the can trapping the lamp and allowing the lamp to make contact on the flange.  The outside diameter of the cap is a snug fit into the hole in the reflector and a slight clearance fit in the hole is the small parabolic metal part.
The purpose of the small parabolic part is not clear.  Maybe to fix a mistake in the focus?
This is a much more complex way of holding a PR series pre focused lamp than the more modern flashlights and is probably one of the first flash lights made to use the pre focused lamps.  A 2 D cell light most likely was the first.

Eveready No. 1653 Electric Candle
This one has a rotary switch on the bottom with positions for OFF, Auto, On and a push button that will turn the light on when in Auto mode and it's lifted.  Two concerns:
  • Old batteries have drained into the cup of the base where the battery spring and a post are located.  The post is threaded and unscrewing it gives access to the switch compartment.  The cup has been sitting a for a number of days, hopefully I can get into the switch compartment and clean it up.
  • The three dots in the black band are Radium activated glow in the dark markers.  The idea is that when you need to find  the light when it's dark, the marker dots will guide you.  On this light so far I haven't seen them glow.  They do emit about 10,000 Counts per Minute into a pancake Geiger tube.  These are not dangerous if left alone.  It would be bad to sand the dots and make radioactive dust.
On the bottom is a metal plate that's attached by what looks like tubular rivets, but they are really part of the candle pot metal base that's been treated like a rivet.  To remove the metal plate just grind off the top part of the rivets.
On the back of the switch lever and a part of it is a stair step contact.  Below is a lever hinged on one end from an insulating block, a spring connects the lever to the center contact that goes up to the battery spring.  The other end of the lever is pressed up against the black button.   My switch was not working.  The problem was that either the star washer that you can see on the bottom center which is supposed to take all the slack out of the switch lever to metal plate joint lost it's spring or the lever got bent a little.  By reforming the lever with pliers it now works like new.  To reattach the metal plate the holes were drilled and tapped 2-56 and pan head screws were used.
Eveready No. 1653 Candle stick light showing switch
Eveready No. 1653 Candle stick light showing switch

The three screws are replacing the pot metal that was formed like an eyelet to hold the bottom cover.
The black button is the switch used for automatic operation.  The rotary switch is labeled "Auto" and the positions are Out (shown) off, "Constant" auto function works and "On" where the light is on all the time.
It seems the labels don't match the function too well.

Table Lights

Eveready No. 2238 Table Masterlite

The model 2238 is part of the Art Deco Masterlite series and is a table light, not a wallite.  In 1935 they sold new for .50. At 6% per year inflation that would be 6 in 2008.
When sitting on a table it's pleasing to look at.  If you grab the milk glass globe and lift it very gently the light does not turn on, but if lifted normally it turns on.
When sitting on the table a soft light comes from the milk glass globe, similar to a candle light, but much nicer since it's diffused and is a warm color.  On the bottom there are 4 rivet heads that it sits on so there's a small gap that lets out a little light from the reflector.
When lifted up there is a reflector and it can be operated like a normal flashlight.   The lamp is mounted "backwards" in the reflector, i.e. the bulb is facing the reflector not the front like in normal flashlights.  This allows light to reach the globe and the reflector.  But it makes it harder to adjust the focus of the lamp in the reflector which requires opening the case, turning the brass knob, closing the case testing the beam shape, and repeating a number of times.
The base is marked:
Eveready Masterlilte Made in U.S.A. Pat. Pend.  
The 1 7/8" diameter glass globe is made with very thick glass and is very strong.  I wonder if it's also used on walking canes?
Uses  a couple of "C" cells.  Weighs 1 pound 3 ounces a substantial heft.  4" diameter x 3 1/2" overall height.
The four vertical ribs are formed leaving a slight gap behind each.  If a flat blade screwdriver is placed in two of these gaps (after rotating the base counterclockwise, there is a recess in the base to make it easy to remove.  The slots to use are the ones NOT adjacent to the two outer rivets that hold the reflector.
Brass sheet metal is used for the wiring and is trapped by wrapping an insulator around it then wrapping other sheet metal.  The same method as used for the Art Deco Pocket light.
A box 4" x 4" x 4" will hold the table masterlite.
Bill Utley's page 224 has a photo of Evenlyn Kelley on the set of "Anything Goes" with the table masterlite on a bedside stand along with a .

Wood Box Table Light


Wood Box Table Light Table Lamp Battery Box & MN1203 4.5 V batt
Table Lamp Wood Box type
Battery compartment holds MN1203 4.5 Volt batt
so why the 2 cell lamp?
This is a table light of the wood box type but instead of the battery compartment holding three "F" cells like most of these (see the for example) this one came with what looks like the original working lamp marked ph. 2.5V 0.2A which implies a two cell battery.  The inside of the battery box measures 3 1/2 x 2 5/8 x 1, but the battery contacts limit the length to 3".
The MN1203 4.5 Volt battery seems like a good fit so I don't understand the two cell lamp?
No markings or makers name or patent dates.  Unknown vintage.

Unknown Walking Cane Flashlight 33"

Walking Cane Flashlight Walking Cane Flashlight Components The sheet metal part holds a single "C" cell.  The tab above the lamp hooks over the lip of the wood cane so the lamp is down from the top but not seated in the bottom of the hole.  The metal cap fits nicely.
A theory of operation is that a (missing) spring pushes the battery and sheetmetal part up slightly which pushes up the metal cap.  When the metal cap is pressed down the sheet metal part comes in contact with either the spring or a metal part holding the spring completing the circuit.  The red O-ring in the cap would hold a glass lens.

This matches the lantern shown on page 5 of the Flashlight Collectors Newsletter edited by Bill Utley - the dates printed on that light (Feb 15 1914 & Sept 22 1915) may be the dates their application was approved, but are NOT the patent dates.  Another theory is that the person who made the artwork transposed numbers (Dyslexic).  For example D46427 is dated Sep 22 1914 which is off by one digit in the year.  2/15/1914 is not valid so try:2/15/1915 - no, 1/15/1914 - no, 3/15/1914 - no, 2/14/1914 - no, 2/14/1915 - no, 2/22/1914 - no, 2/22/1915 - no

Patent Little Stream Line Lantern Patent 2013380
William M. Moxley - Light Weight Lantern Co. Streamline 2 D cell flashlight.
This is the same design as the original Moxley except it's for "D" cells instead of "F" cells.
This light (and the , )was owned by Jack Dale Lewis.  He worked for 40 years on the Northwestern Pacific Railroad, which is a subsidiary of the Southern Pacific Railroad.  He was the "Road Foreman" and "Trainmaster" for the railroad lines from Eureka to San Rafael.  A 24-hour a day, 7 days a week, always on call position, which is why he was stationed in Willits, being it is half-way.  As an "Official" he was not part of the union, received a salary and travel expenses, and was required to wear a suit and tie.  Even so, he did oversee many night time travesties, like train wrecks, etc.  His wife was continually ironing and washing when he would come home full of mud and grease.  Usually his excuse was he couldn't see in the dark and had slipped or fallen in the mud.  William M. Moxley - Light Weight Lantern Co. Streamline 2 D cell flashllight
William M. Moxley - Light Weight Lantern Co. Streamline 2 D cell flashllight


Becuase of their reliability were adopted for railroad signaling.  Very important that train engineer see the signal at night.
This "Little Stream Line Lantern" was made by the Light Weight Lantern Co., 916 Wyandotte St., K.C. Mo.
under the patents marked below.  It takes a couple of batteries the same diameter as the common "D" cell but longer called "F" cells.   For more on "F" cells see my page.  The center off switch selects one of the two bulbs.  Since the bulbs appear to be the same this must be a spare bulb system that can be brought into play very quickley.   Made from sheet brass.  Iron or steel wires used for the stand at the bottom.


Hand stamped in the side NH 332.
One lamp might say T11N and the other 2.5?.  0.37" dia screw base with 0.43" dia spherical bulb

Winchester Repeating Arms Co.

Carbon is a key ingredient of both gunpowder and dry cell batteries.  Both dry cells and metallic cartridge ammunition are metal cans that hold the carbon based chemicals.  So a company that makes black powder ammunition would already have some of the technology in place.  So it's logical for Winchester Repeating Arms Co. to also be in the dry cell business, and the flashlight business to go with it , just like ammunition and guns.

Winchester Hand LampA flashlight with the cap marked:
E. C. Simmons, STEDY-LITE, Trade Mark, Made in U.S.A.
and the switch marked:
Patents: Jun 29 20, Aug 17 20
Those dates match patents 1344735 & 1349860 and the design of the flashlight also matches.
But the assignee is the Winchester Repeating Arms Co. so Simmons was making these under their patents.

Pocket Flash Light with Lens and accidental on prevention switch

1471185 Hand Lamp Switch, Oct 16, 1923, 200/60 ; 235/63A - pocket flash light larger hole admits button, narrow slot prevents activation
Probably not this patent but the switch is similar.
The top slips off to change lamp.  Battery door is hinged, but has some depth, not just a flat plate.
Probably 3B cell battery.
There's a nice silvered reflector above the socket, but the spherical lamp marked "MAZDA" has a horse collar made of white plastic that covers up the reflector.  What's up with that () or if you know anything about this pocket flash light?
Approximately life size.

1035426 Device for Examining the interior of pipes, William W. Dixon (Union Clay Prod),  Aug 13, 1912, 362/253 ; 359/367 - periscope & flashlight
The top (left in photo) part with the lamp and a mirror can be pulled completly out of the battery holder part.  The metal case is one electrical terminal and there's a slip ring in the top and a contact in the battery holder part, so you can rotate the top mirror to any angle desired.  No switch.  If the top part is pulled out or pushed in past the slip ring the light will turn off.  I did it by pushing in but a few minutes later when it was picked up the battery compartment was very hot and the cells dead.  Pushing in caused a short between the ring contact and the case even though the contact is wrapped in fiber insulation material.  Best to remove the batteries when not in use.
The top mirror was loose but a few drops of super glue fixed that.  The lamp is on in the photo.

D46279 Electric Hand Lamp, John H. Goehst (many paents assigned to Federal something), Aug 18, 1914, D26/50 -
The wire at left did not seem to fit the top of a No. 6 Dry Cell and so was replaced with a phospor bronzestrap spring to connect the negative battery terminal to the back of the reflector.  That wire spring might be correct for a dry cell that has large posts with tapped holes ? 
The lamp uses white plaster of paris to hold the bulb and is stamped: pat Nov. 8, 1904  See
774404 Base for Incandescent Lamps, Alfred Swan (GE), Nov 8 1904 -
The lamp works fine on a 1.5 Volt dry cell (actually my No. 6 Battery Adapter).
The bail is missing and can probably be replaced with one from a paint can.
Reflector is silvered so a light application of silver polish made it shiny.  Also has a plano convex lens.
This has a resemblance to the Delta and the Wheeling Stamping Co
Although the head has an appearance similar to a casting, it's plated sheet metal with rust. D46279 Portable Electric Lamp uses Dry Cell The metal strap on the No. 6 Dry Cell (adapter) is phosphor bronze and is very springy.
The bail fits very well and came from a 1 gallon paint can.

Hipco Dual Lens Flashlight

Flash Light, T. HIPWELL, Jun 22, 1915, 362/204 ; 340/321 - uses two lens head - this is a very interesting idea.  The beam has a sharp edge between the illuminated area and the dark area unlike ordinary flashlights that have the main beam surrounded by light direct from the lamp.
None of the threaded parts of the head are for adjusting the beam, they all are tightened until something is seated.  Maybe by lamp selection or by using shims an adjustment could be made to make the beam even brighter?
Flash Light, H.H. & H.T. Hipwell, Aug 10 1915, 362/205 ; 362/208 - ribbed tube part of switch design which uses center contact of lamp as one side of the switch.  Isolating lamp mechanically from battery.  No way to lock light on or off in patent.  Actual flahslight has dimple to hold switch off, but nothing to hold it on.

Hipwell patent 1853271 1853272 Speed Flash Gun
Flash Lamp Structure for Cameras, H.T. Hipwell, Apr 12, 1932, 396/184 -

a spring when released both compresses air in a cylinder to trip the shutter of a camera using an air type remote shutter and at the same time fires flash bulbs.

1853272 Flash Lamp Structure for Cameras, H.T. Hipwell, Apr 12, 1932,396/184 ; 200/547 -
The attachement is a spring loaded air pump that's connected by hose to the bulb socket on a camera shutter.  Air type cable releases are/were common.  When the trigger on the air pump is pressed the camera makes an exposure and a switch complets the circuit firing the two flash bulbs.  I've hand sketched the two Edison base flash lamps and the reflectors that are behind them.
The label calls this a "Synchronous Speed Gun".    "Gun is short from Flash Gun.  A very popular press 4x5 camera was the "Speed Graphic".

Auto-Magic Pistol 16 mm film strip projector


Auto-Magic Pistol 16 mm film strip projector
Auto-Magic Projector Pistol with dummy film and lamp on
The projected image is inverted.
The loop is 30 frames of 16 mm.
Maybe Super 16 or maybe plain 16.
Image is formed between 1/2 foot
and a couple of feet from muzzle.

In the top half in the optical path you can see a vane
sticking up.  It sets the right frame edge.  Since the
perf is at the bottom of the lower half.
If the height of this vane was reduced 2.1 mm
(i.e. (S16) 12.35 -(regular 16) 10.26 = 2.09 mm)
and if the optics work, then Super 16 frames could
be projected.  East to test, just lift it up a couple of mm.
With the top open you do see the full super 16 frame.
With the lens out as shown at left the distance to the
screen is 6" and the image is about 2 1/2" wide.
Need to wait till dark to check the largest size image.

Auto-Magic projector pistor film strip
Single perf 16 mm film 9" long (30 frames).
This is polyester base which will not snap
when bent but you can't use a normal splicer.
Tape splices work.
The marked frames are shown in order.
The "1" is wrong, it needs to be mirrored like
the "2" which is correct.  If you tilt your head
to the right the numbers read correctly.
Instead of writing backwards on the outside you
could write normally on the inside.
By comparing a photo of a projected image and
the film the frame size is the standard 16 mm
10.26 x 7.49 mm, NOT Super 16.

Paper Doll from 3739225 2739225 Disposable Flashlight, Horace B. Rowland, Mar 20 1956, 362/189 ; 273/155; 362/208 - paper doll

a sheet of fibrous material that can be folded to enclose two cells and a lamp, sold flat. minimalist design uses tin foil. Photo is a paper doll made by cutting out the patent drawing.  There are two pieces that get stapled together.  I expect  you could buy something like the above all cut out and with the metal layers attached and with eyelets or staples mailed in a flat envelope.
When ready to use a two cell lamp would be screwed into the large sheet with it's base contacting an eyelet at 62 and the box folded up.  The string and button type of office closure is on the outside to hold it together.  Not sure what size battery it was intended for, could be dimensioned for almost any pair of cylindrical cells.
One of a number of minimalist flashlight patents.

Either three "C" cells or three "AA" cells can be installed.  There is also provision to recharge them in place.
Note earlier versions of the Petzl head lamps used the unit style 4.5 volt battery (3R12, MN1203) with tabs, so using three cells allows for the same lamp options, i.e. a general purpose lamp or a high brightenss lamp.

When the lens ring is screwed down tight it opens the electrical cirucit.  When unscrewed the lamp is turned on and the beam can be adjusted.

Wall Eye 2 D Flash Light Lens & Circuit Closure Gold Stripes in Groups of 3    Eveready?
Insulating washer on disk

This Flash Light has no markings.  It uses a glass lens that is NOT it's focal length from the bulb but instead much closer.   In the photo above you can just make out the broad hot spot about two diameters in front of the lens.  When the lens is moved a couple of inches forward the hot spot is just a few degrees wide, but it would take a longer tube to hold it there.  So by locating the lens where it is the beam is something like 100 degress total.  Lens has a focal length of about 1 5/8" but is mounted about 1/2" from the filament.  Maybe this is the wrong lens for this light?
The Lens is convex on the outside and concave on the inside.  The inside is also recessed.
The circuit close/break is done in a way that's similar to the Eveready Pocket Flash Lights, that's to say the switch has one side grounded to the case, so the switch in the picture is making contact with the case.  The reflector, bulb holder has a disk connected to the threaded part of the bulb but that is insulated from the metal reflector (and case).  The center of the bulb makes contact with the positive battery terminal.  The switch connects the case to the disk.  The conducting disk as half of a switch where the other half is the sliding part and the use of an adjacent insulating disk so that the metalic reflector does not connect the lamp base to the flash lite case is used in the following National Carbon Co patents:
1157395, 1226634,  1312220,  13315262,  1388165  and probably others.
If this was a depression era flash light then the use of a single rivet to attach the switch surly was a cost saving compared to other switch designs that use 3 , 4 or more rivets, with there associated holes and installation labor.
The body was black and there were gold stripes in groups of three running parallel to the long axis.  The head was plated, maybe Nickel and the battery brass battery cap was black.

What Goes Wrong

As received it was DOA for function, but the lamp is good (although impossible to remove).  The problem was corrosion at the joints.  After dissambely and scrubbing all metal surfaces with Renaissance Metal De-Corroder and a through rinse under warm tap watter and a good drying including some canned air, it now is functional.

May Baby Torch

May Baby Torch 2 C cell Flashlight with spherical lensThis is my first attempt at using an external flash as the main light and the camera flash for fill plus a light box made from a Priority mail carton and some printer paper.  I'm happy with the result, taking photos of glass or mirrors is difficult.
Cap marked: May Baby Torch, May Mfg Co, Pasadena Calif.
Switch marked: Made in U.S. A. and Pat. Apl'd For.
You can see that the forward part of the lens has a flat on the inside and that part acts like a lens and focuses the light in a forward beam that's rather wide.  To get a narrow beam the glass would need to be maybe an inch forward of where it is, so the intent was to just brighten the forward light a little.  The rest of the glass is not a lens and just lets the light out for low even illumination all around.
So far haven't found a patent for this light, if you have the patent number .
There is a lamp extender.  It has an E10 socket on one end and an E10 plug on the other.  It's about 1/2" long.
Maybe this was a modification of a more normal flashlight?
There's also a May full size torch that uses "D" cell batteries instead of the "C" cells used by the Baby Torch.
2017 July 20 there is a similar flashlight on eBay made by Perko for use on a small boat.  It has a metal rod coming out of the battery cap with a 2 foot long rod and clamp.  Instead of the clear globe lens it has a Fresnel lens.  Maybe from 1910.  A very similar item by Perko has a switch patent date of Dec 20, 1921 (see 1287262 ).

Pocket Flash Lights & Vest Pocket F.L.

This next patent is prior art to a battery powered pocket flash light.  Notice it was called a Pocket Lamp.

Oil Burning 1881 Pocket Lamp patent 246794
246794 Pocket Lamp and Friction Lighter Combined, T. Lawrence, A.C. Stratton & J.M. Wolf, Sep 6, 1881, 426/494 ; 203/41 - the oldest patent I've found with "pocket lamp" in the title.  It's interesting that these were called lamps and not lighters.  The next generation used a wheel holding a number of flints which when spun would shower sparks on the wick.  The newest oil burners used a cylindrical package sort of like two lipstick tubes with a square block in the center.  When you pulled them apart you were stretching a spring and opening a window that admitted one BB sized flash bang pellet.  When you let go the pellet was jammed into serrated jaws making a lot of sparks and lighting a wick fed oil from the opposite lipstick tube.
You can see the family resemblance with the electric versions.
 

Pocket Flash Lights have a similarity to bicycle lights, but are much smaller and the lamp is usually pointing up rather than forward.
They were made in different sizes, where the design is the same for all of them.
The tab type unit cell 1.5 Volt  battery has an appearance like that 4.5 Volt bicycle unit cell, but it's only 1.5 Volts and smaller.
The narrow Pocket Flash Light uses an eyelet instead of the rivet at (11), the contact in made by bending the spring (10) rather than the stud (7) and the slide switch (13) has open ends which cost much less to make than the closed end version used on the patent style light.

Shooter transmits an omnicirectional radio pulse coded signal and all targets that would be hurt by that type weapon respond with an IR pulsed signal.  The shooter has a 3 lens optical IR sensor boresighted with the barrel so only a traget that was aimed at would count as a hit.

1122777 Electric Switch, A.S. Lyhne (Franco?), Dec 29 1914, 200/60 362/205 - clamshell PFL
The switch is an improvement on the type that depends on one of the battery tabs, which may be bent or twisted.
Also uses the cigarette lighter case type of latch where the edge of the sheet metal spring is the button.  On the opposite part there's just an inward dimple that gets held by the rectangular opening  in the latch sheet metal.  The round object just to the right of the latch is a rivit holding the latch-spring in place.
The reflector is a seperate part that has been soldered to the top case.
Overall size 3 3/4 x 2 3/4 x  1 thick.  AA cells are way too small, probably uses what's called a 3 "B" cell battery pack.
Lamp is glowing dimly at 1.5 V and 200 ma.

Burgess Snap-Lite

Burgess Snap LIte No. 942The Snap-Lite was a very low cost light based on two AA cells side by side with a lamp connected to a lid.  When the lid is opened it both rotates the lamp and turns it on.  These were imprinted with a business name and "Compliments of . . ." as a giveaway item.  The cells can not be replaced so it's a throwaway, but some people kept them even though they no longer worked.  This was the first use of the Burgess patent 1307868 which involved forming the Zinc can as one piece of metal instead of the prior method of soldering a cylinder then soldering a cap to the cylinder.  Apparently the internal chemicals are exhausted before the zinc has a hold eaten through it, hence a number of these still survive.
Photo i s of a No. 942 Burgess Snap Lite.  In the oval on top is:
patented

SnapLite
Flashlight
Burgess Battery Company,Stamped in U.S.A. 
On the clip that holds the screw based lamp:
Burgess,
No. 942

 The clip that holds the lamp is seperate from the lid and can rotate indipendtly of the lid, so it's not clear how the lamp gets turned on.

Stamped into the floor of the top compartment: 52

Burgess Snap-Lite No. 4

Burgess Snap-Lite No. 4
, pg 74 - 75, shows three styles of Snap Lite: the earliest have the dark brown case like this one, the "Number Two" has a red case and the newest ones are Art Deco styled.  The book says they all are 2 3/4" tall.  This one measures 2 5/8" closed and 3 3/8" open.
There are a few patents for a light that has the look and feel of the Snap-Lite by other makeres so they seem to have been quite popular.

  Eveready Pocket Flashlight No. 3

Eveready Pocket Light No. 3 On
Eveready Pocket Light No. 3 Inside
Eveready Pocket Light No. 3
There are a number of things about this Pocket Light that are very different from the earler Pocket Lights.
The instructions say to split a 706 battery apart and use half on each side.  But a standard AA battery fits.  Maybe this was the first AA battery application?
The lamp is under a plastic diffuser.  I think plastics like this were only available after W.W. II but Art Deco () was a 1920 to 1939 period?
Dating this is not easy.  So far the patent has eluded me.
All the early Pocket Flash Lights used the unit battery with top mounted tabs and that's what I was expecting this one to also use.
If you have nay info on the Pocket Flash Lights please .
The two AA cells in the photo are in the same orientation as they go into the light.
The plunger at the bottom pushes the frame up and out of the case when the button is pressed.  The plunger is also the switch.  When the plastic diffuser is pressed back down inside the case that opens the switch.  On the bottom left you can see two rectangular holes.  The metal from the top hole is folded in and down and from the bottom hole is folded in and up.  They both wrap around some fiber insulation that in turn is wrapped around a brass or copper strap.  There are a number of these anchor points to hold the sheet metal wiring.   The bulb is a #14 which is a common screw base 2 cell flash light lamp although the instruction sheet says to use a 1180 bulb.  If  you know what that is please .

Eveready No. 4758 3-cell Wallite with Timer-Switch

Although not a pocket flashlight I'm putting this here because of it's strong relation to the No. 3 Pocket Flashlight immediatly above.  They both use the same construction technique where metal straps surrounded with fish paper are used as electrical wiring.  As of 31 May 2008 the patents for both of them have not been found.  Although 1913696 Self Contained Lighting Unit, Wiley (Delta Electric), Nov 13 1933 came a year after the Wallite it's very similar.
Eveready No. 4758 3-cell Wallite with Timer-Switch
Eveready No. 4758 3-cell Wallite with Timer-Switch
Hook on end of chain allows holding chain
in out position keeping light on.
This unit is mounted using the three holes in the back plate. 
The front cover has two tabs that fit the slots.
The slots have spring wire at each end that grabs the cover tabs.
The Wallite can be mounted not only on a wall but also a ceiling.
The printing says "Brass cap of battery should point in direction indicated"

Pertrix


Pertrix Pocket Flashlight0.971" thick x 2.65" wide x 4.3" high.  Most likly takes a three "A" cell battery like the MN1203.  So it's 19teens.  The switch is unique.  Under the button is a narrow post and below that a disk.  The leaf spring pushes the disk up into the round hole locking the light off.  to turn on push the button and while holding it down slide down.  The top lens is oblong as is the reflector.
Probably European.

The cap has been crushed.  It would take many tons to crush the cap so most likely the cap was off the lantern and run over by a heavy truck.  Looking for a local shop with a hydraulic press.
In the open view you can see how simple (Elegant) the design is.
Under the central eyelet in the cap there's a holder for a single spare lamp.
It uses the 502 lamp.  The metal plate that's the reflector has very high quality plating that polishes even today to a shiny finish.

Pyle-National Company

This company made parts related to carbon arc lights then they made a combined steam turbine and electrical generator specifically to power an electric headlight for steam locomotives.  Later they got into making warning lights for locomotives, the idea being to oscillate or wobble the headlight so that the light is more attention getting.  Warning lights for firetrucks have a similar function and work in a similar way.

This may be a train headlight, Crossing light or Ditch light. where it was used.  These two lights were from Jack Dale Lewis who also had the The base flange casting broke and a steel plate has been screwed on with the same hole pattern as the original light.  I have two of these lights and both of them have have this same repair.  That indicates that they were used in a high vibration enviornment and were liked enough to make the repair to keep them in servide.

Lamps

Flashlight lamps first of all must have an operating voltage that's compatible with the voltage supplied by the flashlight.  But after that the current (or power) of the lamp is related to the capacity of the battery.  Common 2 D cell flashlights use the #14 lamp which is 2.47V @ 0.3 Amps or about 3/4 Watt.  The No. 6 Dry Cell lamps are rater much higher in power.

These are 12 Volt lamps that have the same 15 mm double contact bayonet base as the 1.5 and 3 Volt lamps that many of the No. 6 Dry Cell lanterns use.  The idea is to replace two No. 6 Dry Cells with two 6 Volt lantern batteries for a total of 12 Volts.
These are all single filament lamps that are wired to the two contacts, not the shell.

1209 Lantern Battery with Thumb NutsMost of the lantern batteries seem to be the spring top type, not the screw terminal type so the spring top needs to be adapter to allow connecting the lantern ring tongue terminals.  
But the lantern battery may not fit all the No. 6 Dry Cell applications.  For example the Gray Navy Battle lantern would hold two lantern batteries, but you can not easily install them because the switch bracket and switch is in the way.
This battery contains four each .


Many of these patents are in class 362/194 and relate to a cap or cap and handle to be added to a No. 6 Dry Cell to make it into a lantern.



Burgess BL-6 Lantern two No. 6 Dry Cell

Burgess BL-6

(Burgess Lantern for the No. 6 Dry Cell?) although I don't see any markings other than the top which may say (it's very faded) Burgess Lantern.  It's seen heavy use and some minor battery leaking.  The switch needs some work as it does not want to make the circuit.  Next to it is one of my low cost Battery Adapters.
I'm putting the photo here pending finding a patent to go with it.
The lamp is the wrong one.  It's marked 3.8 V and should be about 2.7 V for a two cell light the highest wattage lamp since the No. 6 Dry Cell can supply the current for a long time.  Although there are not many choices (i.e. # 14) for a two cell E10 base lamp.

Navy Battle Lantern

The Navy Battle Lantern  9-S-5293-L, TYPE-JR-IS


uses two No. 6 Dry Cells to power a 1491 (see ) dual contact bayonet base lamp rated at 2.4 volts.  On the back is a heavy duty cast metal bracket to attach the lamp to a ship.  on the bottom is a socket that will accept the 1491 lamp, but it's intended to be wired to a relay that turns on the lantern when there's a failure of the ship's AC power.  The same 10-24 screw is used to hold the top battery compartment cover as to hold the lens bezel.  Various parts have a dash number after the lamp number of 5293.
Handle marked 5293-L-5
Lens bezel marked 5293-L-4
An eBay lantern that looks very similar has the top marked 9-S-5311-1, yet other parts are marked with the 5293 dash numbers.  But it does not have the emergency power fail socket on the botton and it uses a standard toggle switch.  This switch looks as if it could be controlled from a remote rod or other mechanical acutator.  If you know, .
The 1491 bulbs tend to seperate from the base when any torque is applied.

Bell System Dual Head Lantern
Carpenter "Bell System" Dual Head Lantern One beam on the left is a spot type and there's a focusing slider on the other side to get focus.  The reflector is polished.  The reflector on the right has a matte finish and there's no adjustment, so is an area beam.
Uses two No. 6 Dry Cells
The lamps are marked Carpenter Boston 45 Mass
23-C
Master Light
The rubber ring is also marked "Master-Light-Makers".
The rubber on the left is in poor (cracked) condition and the one on the right is missing as is the glass on the right.  where to get the rubber and glass.
Neither lamp would light after installing a couple of No. 6 Dry Cells.  The lamp and socket contacts were well oxidized and there was crud under the switch contacts.  The C&H switch has open ends so it's easy to clean.  Now both lamps work fine.
Dual No. 6 Dry Cell Lantern with Five Inch Reflector

Dual No. 6 Dry Cell Lantern with Five Inch Reflector


No markings of any kind.
The white plastic tube that surrounds the lamp is attached to a slide lever on the rack, the idea is you can slide it forward to diffuse the light for a broad beam or retract the diffuser for a powerful spot beam.
The problem is that the white plastic has shrunk and no longer can be retracted.
If you can identify this lantern what it is.

Can with top mounted reflector, single No. 6 switch lower than the above an moves in arc
There are no marks of any kind on the lantern but it matches the drawings in 1152082 and the switch works the same way.
The same company made a Toy Electric Engine that sounds like a steam engine .
Flashlight Collectors Newsletter 20 has an Old Sol ad (July 18 1915) that seems to show this as Old Sol No. 28. 
The Old Sol name also shows up on the
Switch was painted, needs cleaning
A prior owner painted everything on the outside and inside, including the switch.
It's apart so that the paint can be cleaned from the electrical contacts.
The small fastener has a split shank and is bent open to anchor.  What is it called?  .
Also whatever insulator was between this hot circuit and
case ground was lost by a prior owner as well as a couple
 of the split fasteners that hold the switch board  to the cap.
They can be replaced by 1/8" eyelets.
The ground strap also had paint in the electrical joint.
No. 6 Lantern Switch top side
All the metal you see on this switch is from the hot battery
 terminal, the other battery terminal is connected to the
cap.   This if the top face of the switch and faces the bottom
 side of the metal cap.  As received there was a dead short
 between the switch and cap.
By placing fiber washers between the swtich board and cap
 the metal will be spaced away.  Adding some 3x5 card stock
will prevent a short is one of the metal tabs on the left starts
to migrage to the cap.
No. 6 Lantern Working
Working after repair 25 Feb 2008.
Note the can has no electrical function.
It helps to have small fingers (I don't) to install and tighten the thumb nuts on the battery.
No. 6 Lantern Switch Repair & label
Fiber washeres to space the switch board from the cap and card stock as extra insurance aginst a short was also used to make a label.  Eyelets attach the switch board and ground strap to cap.

Grether Fire Lantern

There are a number of patents that cover this general type of fire lantern.  But so far I have not found the one dated June 24 1913.  If you know, .

The label says:

Made in Bridgeport, Conn, U.S.A.
  Army-Navy Special
  OLD-SOL
  Reg  in U.S. Pat Office June 24, '13
Type No. 158-RB
Hawthrone Mfg. Co. Inc

Grether Fire Lantern The push buttons for the ON-OFF switch were missing.  I've replaced them with a
couple of 10-32x3/4" hex head machine screws.  There is a rod sticking out the back
along the center line of the lamp that moves the lamp front to back to allow adjusting
the beam.
The lens and bezel came with the lamp but the casting at the top has broken.  Maybe
the local specialist welder can repair the aluminum.
Uses the 1491 lamp, same as the Navy Battle Lantern which also uses a pair of No. 6 Dry Cells.
Grether Fire Lantern Switch & Spare Lamp Storage
The Battery contact plate has been removed and you can see the combined switch and
lamp axial movement part.  The loose wires normally would go to the contact plate which should have leaf spring contacts to the four battery terminals.  Since it's missing parts
someone has disconnected the wires to allow direct connection to the No. 6 Dry Cells.
Also notice that two spare lamps can be stored inside the top.

The angle of the upper right groove is wrong for No. 6 Dry Cells, so maybe
this lantern was made to use another battery like an Edison cell?

Portable Electric Lantern, William Grether, Jan 14 1919, 362/188 ; 362/197 - Two No. 6 Dry Cells, focus adjustment on same centerline as lamp

Uses the leaf spring method to connect to the dry cells BUT uses a wire jumper between the two dry cells and does not have the insulating alignment plate like 1348128.

This patent contains the following wording:  "The means above described make it possible to remove the cover (5) from the base (1)  and without bothering with long connecting wires, and further making it possible for the cover to be taken any distance from it's base."  What does this mean?  Maybe the 1913 patent would shed some light on this?

looks like Grether fire fighting lantern
The two No. 6 Dry Cells are connected to a fiber plate using the thumb nuts.  These assemblies of two dry cells can be pre made and stored in a fire truck.  When new batteries are needed it's done by opening the toggle levers on the lantern and removing the top completely from the bottom which is easily done since there are no wires going to the batteries but instead leaf spring contacts (the heart of this patent).  The dead battery assembly is lifted out and a fresh battery assembly installed.
A better title would have been "Quick Change Battery method".
Niagara patent 2425274 calls this patent.  It uses very similar leaf spring battery contacts.


1369892 Lighting Apparatus, Ellsworth A. Hawthorne, Mar 1 1921, 362/188 - The Excellight two No. 6 in patent, also offered B version with Edison Alkaline

The push right for on, push left for off switch assembly combined with the bulb focusing function in this patent matches the lantern in the photo.
But this patent shows wires running to the batteries and so does not have the quick change battery feature like the lamp in the photo.

Repairs

For now I'm using hex head machine screws to replace the on-off switch. 
Haven't yet figured out what the battery contact straps look like.
If an O-ring  was to be used between the bezel and the top it would have an I.D. of about 5" and the exact same O-ring would be just the correct length to fit between the top and bottom.  Concidence, or is that what should be there?
If you have any information on this lantern .

Battle Lanterns

There have been a number of lanterns for use in battle areas.  The classic Naval Battle Lantern (See ) used a couple of dry cells.

The more modern ones use the 529 or similar spring top 6 Volt lantern batteries.  The two most common types are the all battery version that's an almost cube plastic box holding a couple of lantern batteries and a sealed beam 6V lamp (both of these are typically yellow), or the same lantern with a relay that turns on the lantern when the mains power fails.

This Rolfan lantern is based on the common dual battery 6 Volt sealed beam design except:

  • One of the batteries has been replaced by a 120 VAC power supply/battery charger Rolfan model 1546
  • There's a toggle type On/Off switch
  • The color is red
  • A base been added that allows tilting the beam up or down.
  • There a DC voltage meter to check if the lantern is ready to use.
  • It does NOT have a carry handle, which it should because it's awkward to carry.

Rolfan Type 1513 115 VAC 1/4 Watt Flight Line Lantern

When an Alkaline 529 ^ volt lantern battery is installed (it takes a flat blade screwdriver to get the springs down below the metal contact bars) the meter reads zero, but when the switch is turned on the lamp lights up and the meter reads a voltage.

The lamp is marked:
GE
4547
4.75 Volt
Hand Lantern The power supply is marked:
The Rolfan Co.
Battery Charger
Type 1546
Output: 6 V 300 ma
Charger BLue Pos.
Leads Green Neg.

The problem is that you should NOT use a float charger on a primary battery.  This lantern was designed to work with a rechargeable an lead acid 6 Volt battery.

Note: modern chemistry batteries like Ni-Cad or Ni-MH or Lixxx require a much more sophisticated charger circuit than the simple transformer - diode charger in this lantern.
The Power Sonic PS-650LS looks like it may be is the correct battery, one is or order (8 May 2014).
15 May 2014 - battery arrived and after a struggle (There must be an easy way to compress the springs when installing the battery, ) it's in and works.
Now to find a charging AC line cord.

Army Angle Head Flashlight MX-991/U

Army Angle Head Flashlight MX-991/U ExplodedThis 2 "D" cell flashlight comes with a clear mild diffuser, a white diffuser and a red filter along with a spare bulb stored in the battery cap.  I think this design is of W.W. II vintage.  The current popular flashlight (2007) are the Streamlight brand or knockoff versions that use the CR123 photo batteries, which the military calls the BA-5123.  These batteries have excellent shelf life (> 10 years), contain a lot of power for their size and weight, and can deliver high currents.  A modern double 123 battery flashlight is probably a better flashlight than the old angle head on all accounts. 
The brighter Streamlights use gas (krypton, Argon)  filled filament bulbs that provide more light than conventional filament bulbs.

The ball on the pocket clip is a switch contact connected to the metal body.  There's an insulating fish paper sleeve inside of which is a sleeve of metal that connects to the battery spring which is insulated from the case.  A hole in the fish paper allows the ball to make contact with the metal sleeve completing the circuit.  action: OFF-(ON).  Uses bayonet joints between the reflector/lamp holder and the tube and between the large and small tubes.

Flashlight, William B. Sachs, Nov 18 1930, 362/206 ; 200/60 -
The patent shows a knurled button that can be used to turn to lock on, this button is smooth and does not lock on, yet the clip is marked VES POC LITE.
The other two Ves Poc Lites I've seen on the internet have also been green.
The patent shows an optional lens assembly that can be fiiction fitted to the front where the normal lamp is a 223 type flat globe type.  The lens is in a fixed position.  The sheet metal socket that can be slid back and forth in the lamp housing allows focusing the optional lamp holder.  This light is missing the battery spring and the bakelite insulating washer that holds it.  So far have not found an earlier Sachs flashlight patent that would cover this one.
Ves Poc Lite Opened
The prior owner had installed the sheet metal socket improperly.  It can be installed with the flange toward the back with the threads inside the lamp cap, but then there's a large gap between the rear battery and the switch.  But that method does allow the use of a 222 lamp.  The patent shows the socket installed behind the lamp cap with the flange adjacent to the lamp cap.  For that to work the lamp needs to be either a 223 type (shown above) or a #14 so that he bulb can be trapped by the step in the lamp cap internal bore.
When assembled acording to the patent with the 223 lamp the spring shown from a AA battery holder causes this penlight to be on all the time.  Some type of insulating holder is needed between the spring and the metal cup on the back of the switch to get it working properly.
Also the two end caps are not as tight as they might be.  Instead of using threads which are not practical inside the tube since it's made of 10 mil brass there are three dimples spaced 120 degrees apart.  I think these need to be reformed, maybe by using an automatic center punch on the tube OD to drive the dimples a little deeper.
The lamp cap has the feel of a screw machine or chucker lathe part and the tail cap is a stamped sheet metal part.

The Neuralizer has the ability to erase the memory of anyone who can see it's light unless you are wearing eye protection specifically made to stop the rays.  You don't think they call them Ray Ban for no reason.  The first public information on this technology was in the great Albert Finny movie .   Back in 1981 the Neuralizer was much larger, more like a pistol.  But by 1997 you can see in the Movie that it's the size shown above.  The technology did not improve and the 2002 version seen in is the same size.
I think my wife has found where I hide this one because often there's something I should remember but don't.
See my web page on the for a similar technology.

Generator Flashlights

Mechanically powered flashlight ()
(W.W. II)
These show up in patent class 362/192.
I can subdivide 192 into the following classes:
192.1 No Energy Storage - when you stop supplying mechanical power the light stops.
192.2 Energy storage of specified type
    192.3 spring
    192.4 capacitor
    192.5 Battery
    192.6 Gravity
UNE Generator FlashlightThe Flashlight Museum web page shows both UNE and Viva Solar brand names, but they look like identical construction except for the plastic color.  Bulb is marked 2.5 V 0.15 Amp (i.e. a feeble 3/8 Watts).  No storage, you get light only when you pump the handle.  A slide switch on top slides the bulb front to back for spot or area beam.
The Flashlight Museum lists the following brand names:
Collins, Campbell Manufacturing Company
Misc/Unknown
Ivar-Lite
Philips (Holland), Misc/Unknown
Gen-A-Lite

Shake Flashlight (Fake)

These are advertized as not needing batteries, but that's really not the case.  Shake = Fake in this  case, the S015.
If you know of a "shake" flashlight that actually works, .
Shake Flashlight (Fake)In the lower right corner of the box is a battery symbol with a "X" across it.
Click on the image at left to see a larger version.
Shake Flashlight (Fake)This new flashlight is "on" even though it's sitting still to have it's photo taken.  It must have some internal energy storage method.
Shake Flashlight (Fake)You can see the two CR2032 Lithium coin batteries on the bottom side below the switch.
Note the CR2032 ()  is a Primary LiMnO2 battery, i.e. the same chemistry as the common CR123 photo battery, i.e. it is NOT a rechargable battery chemistry.
The moving metal part has NO magnetic properties, i.e. it is NOT a magnet.
Shake Flashlight (Fake)You can see that both wires from the coil are NOT connected to anything, i.e. the whole "shake" generator is bogus.  It seems strange that they would put a dot of paint on the fake magnet.

NightStar RS Shake Flashlight (works)


NightStar RS working Shack Flashlight This is a working shake flashlight, unlike the first one (above) that was a fake.
Uses a 1.0 Farad 5.5 Volt super capacitor to store the energy.  Instead of using rubber bunpers like in the fake light above, this one uses small disk magnets to restrain the moving magnet.  As received it was dead and it took a few minutes to get it going.  The LED has both a parabolic reflector and a lens, like many of the early flash lights.  The light is not that bright but it is usefull.  The RS model is completly sealed to make it water proof (even can be submerged).  The switch uses a reed switch on the inside and a magnet in the knob on the outside so there's no hole needed.

Projection Pointers

These are with a reticle that gets projected.  These were used in the same way as laser pointers () today.  But unlike the red laser pointer that's impossible to see in a video of a lecture, the flashlight pointers can be seen.

Design Patents are very different from the utility patent.  A design patent relates to the look of a product and has nothing to do with it's function.

Inova X1 and X5 flashlightsThe X5 takes two of the 123 photo batteries (positive toward cap) and the Z1 takes a single AA battery (negative toward the cap).  The battery contact at the lamp end is spring loaded and does not make electrical connection unless the switch cap is screwed on to within one turn of seated.  When the switch cap is out one half turn pressing the button pushes the battery stack forward for momentary contact.  Turning full in locks the light on.  Turnint out 1 turn locks the light off.
The cap is supposed to be held from rotation by the O-ring, but it's missing on the X-1 so have asked Inova how to get replacement.  After I found it on the floor and put back it's working fine.  Inova responded the next business day and said all the products have a "limited lifetime warranty" and they would send me and O-ring or tail cap.  EXCELLENT CUSTOMER SERVICE.
These are constructed in a very rugged manner.
I also have their 24/7 light which is a multiple LED light which displays different patterns depending on where the rotary switch is set.  It has different power levels and different colors and an SOS in Morse code mode.

The Terralux circuit is based on the TI TPS61040 Low-Power DC/DC Boost Converter in small surface mount packages.  The LED current is fixed so there are different part numbers for different internal switch max currents of 250 ma = 61041 and 400 ma = 61040, but these are NOT the average LED currents, which are much lower.
These are rated for input voltages between 1.8 and 6 Volts.  The output voltage can go up to 28 V allowing for driving a series string of LEDs.  The undervoltage lockout turns it off when the voltage goes below 1.5.  This IC was designed primarily for use in the regulated output voltage mode for driving LCDs.  The internal voltage reference is 1.233 Volts and would normally use a current sense resistor of 62 Ohms for 20 ma.  But there are some tricks that can be done to lower the resistor value to save wasting power in the resistor.
To drive LEDs from voltages below 1.8 the TI TPS60300 voltage doubler can be used to boost a single cells voltage.  But in all cases the average LED current in on the order of 20 mA which is the common current for plastic bi-pin LEDs, not the high power type LED like used in the Terralux unit.  Maybe the high power LED is being run at a current far below it's max rating to get better Lumens/watt?  The voltage across the LED is 2.51 when powered in the flashlight.
It's not clear who the maker of the LED is for this unit.  The outline does not match the Cree outlines.

22 May 2009 - although the light is working, it's dim.  The shown both AA cells as dead.  DMM measures 1.0 Volts on each cell.
9 April 2010 - ditto the above comment.  The ZTS battery tester LEDs do the new battery dance but then all turn off.  I use the light almost every day so the two Alkaline AA cells are lasting about a year.
Installing two new Duracell MN1500 w/MAR2016 date code.  Fluke 12 shows 1.622 V(V Check mode, i.e. w/ 1k Ohm load).
1 July 2011 - There's a problem with the Terralux adapter in that it's too good.  The problem is that you can run down a pair of AA cells so far that they start to leak but still the light is working.  This can damage the flashlight.  So it's probably a good idea to replace the batteries even though they are still working every year (?not sure if a year is the right amount of time).
It turns out that if you're using U.S. batteries, Duracell in my case, the lifetime warranty of Mag Instruments covers removing the batteries and repairing or replacing the flashlight.  I removed the Teralux adapter and sent the light back to Mag Instruments along with a copy of the email they sent.  It was a day or two later that I realized I'd forgoten to also remove the short reflector.
When the flashlight came back it appeared to be a brand new unit with the stock bi-pin lamp and stock reflector.  I contacted Terralux and explained what had happened and they sent a free short reflector, Thank You Lauren. 
Now how to figure out a way to be sure the batteries get replaced before they leak?  I wonder if the leaking happens because of the state of charge?

LightStar 100

TerraLux LightStar 100 flashlight The Mini Maglight 2 AA flashlight has much more battery life than it needs. 
i.e. the batteries corrode before running out of power when the TerraLux
adapter is used.  So I suggested that they make a single AA light and they
said it already existed as the LightStar100 so I got one and it's now my
favorite light that I carry all the time.  100 Lumens.
A "feature" I don't like is the 3 functions: full power, dim power and fast blink.
These get activated when I don't want them be the large diameter key ring.
Maybe using a smaller diameter key ring would decrease this? 
Yes, I now use a key ring that's about 5/8" dia and no problems.

Also carried with this flashlight are the   and a Tritium () key chain light - not glow in the dark, but rather Tritium () on 24/7.

Mini

These were designed for use in third world countries (does the U.S. qualify?) so the purchase plan is called "Buy One Give One" where you pay for two and one is delivered to you.  The Mini is claimed to be near indestructible.  Learned about it on the .  It uses a 6602 boost converter IC with external constant current regulation added, plus a TLV431 for the shunt regulator (low voltage version).

  1500 Lumen HID flashlight

Got this on eBay missing parts and maybe with dead lamp module and/or ballast housing (TBD).

Photo as received.  New carry case, uner's manual, parts list, cleaning cloth still in the bag.
HID: High Intensity Discharge () - a Xenon Short Arc () type.
The factory has replaced the bad parts and it's now like in near new condition.

Lumen vs. Foot Candle

Lumens () are a measure of the total light output of a lamp and is typically measured using an integrating sphere ().
The Candela () is the new name for Foot Candle and is a measure of the actual light output falling on a surface.
Lux () is a measure of light brightness per unit area and so is another way of measuring the overall capability of a flashlight.

It's possible to have two flashlights, each of which has the same Lumen output of their lamps and one of them will be much brighter for a given spot size.  This is because the optical design comes into play. 

The AEX25 uses a light source that's a small cylinder and that make for efficient optics.

Most LEDs emit light to the side or into a hemisphere of phosphor so they are harder to match to a parabolic reflector and are not as efficient.

See the paragraph for more on measurements.  The can display either Foot Candles or Lux.

Mounts

There are two ways that the mount can be attached to the flashlight body.  Note that at the base of the body one side is square to the rail surface and the opposite side is a dovetail.  There are two small (1/16hex, 4-40) tapped holes on the flat side.  There are two larger (3 mm hex, 5-0.8mm) tapped holes on the bottom.
The hex head and thread sizes don't seem correct, one is English and the other is metric.  Maybe the two different scope bodies A391132 & A235932 differ, one being English and the other being metric??  if you know.

Surefire Weapon Light Mounting Methods
A391132 M93 on left with 3 mm hex, 5-0.8 mm screws in bottom.  These are larger hex and threads, more reliable.
A235932 M49 on right with 1/16hex, 4-40 screws on bottom.  These are fragile hex and threads.
Note one of the small screws on the side is not seated and the hex driver is not tight.  Maybe the wrong screw?
The M49 two thumb screw mount is attached with two small screws that go into the side of the body.
I think the M50 also attaches this way.
The M93 lever mount is attached to the body with two larger screws that go up from the bottom of the mount.

Sun Flare

A friend likes this flashlight so it came to me to see what can be done to get it working.
The problem was the 4 cell Ni-Cad battery stick which has all cells dead.
The pack is made up of cells marked: KR-1800SCE and they are SubC size (22mm dia x 42mm long.
Although it may be difficult to find an exact battery pack, SubC Ni-Cad cells are available and should work.
But... before ordering replacement batteries, need to find out if the lamp can be replaced.

9 LED

9 LED 3AAA Flashlight
The newest thing for smaller flashlights is to use s.  A first generation LED flashlight uses a number of white LEDs in parallel.  They are sold based on the number of LEDs used since the T-1 3/4 type LEDs all have about the same 20 ma max current ratting.


This is a Made in China product.

Luxeon K2


Luxeon K2 FlashlightThe next generation of LED flashlights uses the High Power LED, like the Philips Luxeon LumiLED K2 rated for 1.5 Amps.  This is a cheap flashlight that uses a resistor to set the LED current.  Since two 3.4 Volt batteries are being used and the voltage drop on the LED is about 3.85 volts that leaves 2.95 volts at 1.5 amps or about 4.5 Watts to dissipate in the resistor and about 5.5 Watts in the LED for a total nearing 6 watts.  This means that after about 10 minutes this flashlight it too hot to hold.


It uses the "Star" K2 which comes on a special laminated PBC where aluminum is part of the board to help with the heat dissipation.

UltraFire C2

Takes a single TR18650 Li-Ion cell.  The clicky switch when on takes a very small pressure to turn the light off.  It does not require a "click", just a little pressure.  A poor quality switch.
It's not clear what's between the single cell and the LED, i.e. is it a resistor, linear regulator, or ??
The Clicky Push-On Push-Off switch on both of the Cree flashlights is very poor.  When  in the on position the slightest thing, not even touching it, will turn the light off.  As shown below the actual switch is 8 mm wide and 14.25 MM outside the leads.  It must fit the 15 mm diameter printed circuit board.  If you know where to get a replacement switch please let me know.
UltraFire C2 Cree UltraFire C2 Clicky Switch Assy exploded
Cree UltraFile Generic Clicky Switch Close Up

UltraFire C3

UltraFire C3 Open
The stock light uses a single AA cell and draws 1.1 Amps.  When the optional extension is added it will hold two AA cells and the current draw drops to 0.54 Amps.  Indorder to drive a 3.5 Volt LED from a 1.5 (or 1.2 volt) AA cell requires a Switching Mode Power Supply to boost the battery voltage.  Since these act in a manner silimar to a "DC Transformer" when the battery voltage is raised the current drops, unlike resistors or linear supplies.  But it takes a special type of SMPS to handle the case where the input and output voltages are the same.  So this is probablu a boost only SMPS hence the input voltage range printed on the back of the head assembly "1.5 - 3.0 V".
The SMPS probably will not work if a third battery is added and may self destruct.
This UltraFile also has the poor quality "Clicky" switch that truns off the light with the slightest of pressure.  Took apart the switch and found a bad solder joint, but repairing the joint did not fix the poor switch action.
You can see the bad solder joint in the lower right.

Cree UltraFire Hwa Wys

This is a single AA flashlight that uses a switching mode power supply and so the LED head will work with a number of battery options.
The eBay listing was titled and 4 flashlights including shipping from China were under .
This is a machined aluminum light with a front lens that slides back for a broad beam and when pulled forward collimates the light so the image of the LED chip is focused thus making a very bright spot.
Note this lens design is in Burgess patent .
Also known as (aka) SIPIK SK68 120-Lumen.
Makes bright military flashlights and weapon sight/target designation illuminators.

Got these to check out some of the things shown on the TV show CSI.  It takes some skill and experience to see anything.  But it's easy to see the hidden UV marks on things like a driver's license or charge cards.  Used the higheer powered (3 each 1 Watt LEDs) 395 nm light for taking photos of the .

Battery Capacity & LED Run Time

Batteries are rated for capacity and LED for current and voltage.  So for a given combination of batteries and a specified LED the run time for light with an ideal power supply can be computed.  A non ideas power supply will reduce the run time, but there's no way to improve it.  There's a complicating factor.  Battery capacity is specified under a given load condition and will change for other loads.  Typically when you pull more current the battery has less capacity.

If cells are conbined to make a battery the Watt Hour capacity is increased by the cell count and in the case of Alkaline there is an added increase because of the lighter loading.
For example a single Alkaline AA cell will powr a 1 Watt LED for 1 hour, so 10 would give 10 hours based on the Watt Hour rating for the battery, but because of the change in capacity with load you get 30 hours.  The rechargeable chemistries seem to provide the same capacity for most loads, the exception is for loads exceeding 1C where the capacity does decrease.
Another factor is that many of the cells have Positive Temperature Coefficient (PTC) resistors built-in as a safety measure.  These have some resistnace at room temperature that wastes power and the trip current will be reduced when the flashlight runs hot because of the LED heat.

Glossary

Size for Hand Holdable Lights

Flashlight -source of light that can be operated using one hand and will fit in a pants pocket.

Headlight - 1. light on front of vehicle like car, truck, train

     2. light mounted on head, the meaning on this page

Pocket light - like a flashlight only smaller, fits into a vest pocket
Penlight - even smaller, fits into a pocket protector filled with pens an pencils side by side
Keychain Light - even smaller, length comparable to a house key
Lantern - source of light that can be operated using one hand but too big to fit into pants pocket
Portable Light - Used on land and too big to use hand held, but can be moved (maybe requires a couple of military trucks)

Function

Illumination - provide general light for the task at hand.

That might be a quarter Lux (full moon) for walking outdoors on a moonless night to very bright for doing fine work in an industrial setting. [patent class 362]

Signal - To communicate information that can change.  [patent class 116]
Weapon - attached to weapon for either general illumination or for aiming
ATEX - Explosive Atmosphere, zone, division, or class 1 is like inside a gasoline tank, 2 is near by and 3 is at a distance where fumes come and go.
Lights on Bouys, Rafts, and Aquatic Devices [patent class 441]
Night Vision - lights can not be visibly too bright so may have an IR output
