A portable source of light probably started with a cave man carrying a burning stick of wood.  There have been many portable light sources based on burning something.  Once the dry cell battery became available flashlights became more popular than they were when a lead acid or other wet battery 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 No. 6 Dry Cell 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 Fire web page for lights that work with fire and/or the Lighters web page.

The key components of a portable light source 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: Dry Cell battery, switch (aka circuit closer), lamp with a filament, reflector and/or lens.

GE 223 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) = 67.259*V + 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.

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 Table of Newer Lamps.  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

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 Loctite 290 (290 Data sheet, MSDS)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.

The tab unit cell for my 2AA Pocket Flash Lights needs to be less than 0.7" some fractions that would work: <= 5/8, 21/32 (23/32 very tight), 45/64.  The 700 is 19/32 which is thin enough by 1.9375" wide by 1 1/8.  If the 1 1/8 is just the body and the tabe stick up the right distance it would fiy my wide Pocket Flash Light.  But it's 2 cells which might burn out the lamp?

	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.
	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. 1053390  Galvanic Cell , Albrecht Heil (Conrad Hubret & Samuel Stern), Feb 18 1913, 429/224 ; 429/229 - Manganic Hydrate as depolarizer gives 1.6 Volt cell 1053505 Galvanic Cell, Albrecht Heil (Conrad Hubret & Samuel Stern), Feb 18 1913,  429/224 ; 429/229 -  Manganese Dioxide as depolarizer gives 1.7 Volts per cell.

	Here the battery is installed the correct way around. 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 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.

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 Hipco dual lens flashlight 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 LEDs.  All of these can be put into an optical integrating sphere (Wiki) and measure the total light output in all directions in Lumens (Wiki) 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 (Wiki) Candela (Wiki) or Lux (Wiki) also see luminous flux (Wiki), Luminous efficacy (300 lumens/watt max for an LED) (Wiki) and the Amprobe (Meterman) LM631A Digital Light Meter.

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 Surefire rail mount 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 AEX25,  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 Hipco 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 (Wiki) 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.
TheWeston Model 594 Photronic Cell was designed so that it measures light with a wavelength response curve that comes very close to the human eye.
The Amprobe (Meterman) LM631A Digital Light Meter 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 Mini Mag Light 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: HID) (see: AEX25) 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

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 let me know.

Supplies needed:
VM&P Naphtha or equivalent
Window cleaner fluid in squirt bottle
Homax - OOPS! Multi-Purpose Remover -
Brasso metal polish
Kroil  made by Kano Labs, 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 Super Lube Gel 82003. other Silicon grease would also work, especially if made under patent 5037566




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

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.

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.

	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 maximum, yet this lamp is rated 3.6 Volts, 800 ma, bulb type B-3½ Base: Single-contact miniature 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.
	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.
	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.

Got this on eBay for 99¢ hopping that the lamp would work in the Eveready 1653, but it uses a 12 mm Edison screw base, not the 10 mm.
Uses a couple of "C" cells for power.  The brass lamp socket works as the switch. 7" tall w/o lamp and 9 1/2" tall w' lamp.

Made in Taiwan
"Solid Brass Battery Lamp"
Item No. 6817
The box shows a red stick, this one has a white stick.

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 $2.50. At 6% per year inflation that would be $176 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.   <--------Turn To Open

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 Western Electric 202 telephone.

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 Eveready Projection Clock 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.

These are very similar applications and it's common for a patent to mention both.

Unknown Walking Cane Flashlight 33"

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.

Patent 2013380	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 Star 222, Conger)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.

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 No. 6 Dry Cell 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

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.

A 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.

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 (let me know) or if you know anything about this pocket flash light?

Approximately life size.

626627 Bicycle-Lamp, ELLSWORTH D. MIDDLEKAUFF (William E. Hall), Jun 6 1899, 362/157 -

In the Murdoch Mysteries TV series S8E18 "Artful Detective"the bicycle head lamp is no longer the bulky electric but a black pasteboard cylindrical hand held type held by a bracket. If set in the 190x time frame that may be too soon for that design of 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 above 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 D46427 and the Wheeling Stamping Co 1152082 Although the head has an appearance similar to a casting, it's plated sheet metal with rust.

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 1143966 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? 1149913 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.

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".

Pre focused PR Lamp

This was a major improvement.  The E10 Edison screw base has no way to control the relationship of the filament location.  The PR (PRe focused, Parabolic Reflector, Prefocused Reflector, or...) base does that.

2097399 Lighting apparatus, Samuel F Arbuckle, United Lens Corp, 1937-10-26, Expires: 1954-10-26, 362/211 - this may be the first patent for a flange type bulb?  I remember these.  They had dimples on the flange and the spring (46) loaded pin (34) that grabbed the flange had elliptical bumps that seated in the dimples so, in addition to controlling the height of the filament they also controlled it's X, Y and theta location.  Although there being 3 pins the lamp would only go in one way. search terms: "prefocus 3-pin flange bulb" "1096 6V Bulb"

2734994 Pre-focus type light bulb mounting, Lloyd T. Fuqua, GM, 1956-02-14, - a lower cost mounting for the above lamp. (after the above patent expired)

continuation of same application used for 2100008 that includes various film strip concepts like external can, internal storage and continuous loop

Auto-Magic Pistol 16 mm film strip projector

	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.
	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.
