While buying some items that have to do with controlling fire for various purposes I tried to come up with a web page title that was general enough to cover them all rather than make new web pages for each one. But I already have a web page for the Big Bang Carbide Cannon and for cigarette and cigar lighters and light sources.
Patent Class 431 is titled "Combustion" and most of what's on this web page falls under this class.
While I have used a number of subheadings below, they are all very closely related. They all use a liquid fuel and need to vaporize it prior to burning. Note that candles and old wick in oil lamps actually are burning vapor not liquid fuel.

There are many ways to start a fire. Cigarette - Cigar lighters used to be common when more people smoked. The flint used in a cigarette lighter is a key element of that device.

Wicks (Wiki) do not work by burning themselves, but rather they use Capillary action (Wiki) to raise liquid fuel near the flame which vaporizes the liquid into a gas that then burns. The strength of the capillary action depends: directly onthe surface tension (Wiki) and inversely on: density (Wiki), inside radius of the tube and acceleration of gravity.
Oil lamps (Wiki) have been around for thousands of years, the simplest being a cup with wick where the flame is close to the top of the liquid so that thick oils will work. Maybe 1,000 years after oil lamps candles (Wiki) were invented. Whale Oil (Wiki) was used in lamps for about 100 years from 1800 to 1900.
Argand Lamps (Wiki) were an improvement on first generation oil lamps and were replaced with kerosene (Wiki) lamps. The key elements were one, a hollow circular wick so that air could be provided on both the outside and through the center making for more light and cleaner burning. Later called a "central draft lamp" and two, raising the fount (reservoir) above the burner so that fuels with low capillary action could be used. This was during the time of vegetable oil lamps.
This particular lamp has been in the same family for a number of generations. They referred to it as the "Whale Oil" lamp and there were Whaling boat captains in the family.

Kerosene LampsThe earliest examples of kerosene lamps (Wiki) were simple wick lamps and later a glass chimney was added probably first to keep wind from blowing out the flame and later to make an updraft to fan the flame. As explained on the Wiki page there are many types of kerosene lamps. One type of plain kerosene lantern is called either barn, hurricane or railroad. These are typically made up of a sheet metal frame that traps the glass globe at the top and bottom and have a bail for carrying or hanging. The "cold-blast" type burns brighter than other versions without a mantle. The earlier "hot-blast" type used air that had been used in burning and so did not have as much oxygen. The even earlier (1850 - 1860) "glass globe" lanterns with "dead-flame" were even dimmer.

You can see them in Fig 1 above, but noticed that the No. 1 lantern does not have wires that made with them so the above lantern does not support tipping the globe.
D51721 Lantern Globe, F. Dietz, R.E> Dietz Co., Feb 18, 1918, D26/128 - Wide top and bottom opening and knobs for tipping.
1476117 Lantern, Duyn Frederick W Van, Dietz Co R E, Dec 4, 1923, 362/177 - the knobs are shaped as ramps or cams allowing the globe to be rotated on the globe plate to engage the globe clamping wires. Since the wires have a concave shape adjacent to the globe knobs it will not rotate out of the locked position.
This has a strong similarity to the Hot Blast patent 89770 (RE8598)
Note there's an air gap between the top of the glass globe and the sheet metal cap just above it.
The wire frame (non tubular) lanterns have no air gap between the glass and the sheet metal top that holds it.

These lamps (Wiki) are similar in that they have a two chamber design. The top chamber holds water and the bottom chamber is for the Calcium Carbide (Wiki) and acetylene gas (Wiki). There is a control that determines how fast the water drips on the Calcium Carbide rocks thus controlling the rate of acetylene gas generation. The gas comes out from a nozzle with a very small hole and the flame is a long pencil like shape. The light is close to white, unlike the flame from burning oil like candle which is very red.
One of the repair shops that worked on my uncle's earth moving equipment had an outdoor acetylene generator that was bigger than me.
Maybe the one described in patent 2189762 made by Prest-O-Lite Co. on or after 1937.
Also see the Big Bang Calcium Carbide Cannon. The cannon uses Calcium Carbide that is the size of coarse ground pepper, but the lamps use small rocks maybe 1/4 to 1/2" across. If they have sharp edges they are fresh. But if exposed to moisture in the air the carbide is a grey color and you don't have as much active material. Calcium Carbide typically comes in a can where the lid is air tight, or in a tooth past type of tube that's air tight.

Miner's Safety Lamp (Wiki)
The idea is to prevent the wick fire from igniting coal dust or flammable gas in a mine and to test for methane, or other flammable gas, and oxygen.
The main purpose was to detect lack of Oxygen (flame gets lower) or presence of Methane (flame gets higher). It will not cause an explosion when Methane is present, like would happen with a Carbide type miners lamp with an open flame, because the metal screen acts as a flame arrester (arrestor?) (Wiki). Note the primary purpose is to detect danger from lack of oxygen (humans need at least 19.5% O2: Sciencing) or presence of explosive Methane gas (Wiki: LOC). Light output was a second order consideration (see Schedule 7A, Procedure below, item 9. Note 0.3 Candlepower (Wiki) is about 1/3 the brightness of a candle.)
In coal mines an open flame or spark can set off a fire and/or explosion. The Davy Safety Lamp (Wiki) separates the flame from any explosive gas mixture using a metal screen that acts as a Flame arrester (Wiki). Also see: Blasting Machines, Gas Cans where the wire mesh cup inside the filler cap is a flame arrester, not a filter.
All three of the below fire safety lamps have a glass I.D. of 2.00".
ReferencesExperiments were done to determine what size hole and what thickness of various metals would prevent a flame from passing or an explosion from passing.
On the Safety Lamp for Coal Miners, with some Researches on Flame, Sir Humphry Davy, Bart. 1825 -
Since the methane burns safely inside the gauze it's fair to say the safety lamp can be used to solve the problem of small pockets of gas. Especially if many lamps are brought to bear. Since hundreds of safety lamps were at a coal mine (and probably thousands of naked flame lamps) this makes sense. A small crew (less than a dozen men) would investigate at the start of a shift and their combined safety lamps could make an area safe.
- The first generation Safe-Lamp had the wire gauze exposed to the coal dust in the mine and did not have a glass, i.e. the light from the lamp went through the gauze. The gauze got plugged by the coal dust. Hence the cap and bonnet to keep of the coal dust.
The lamp is used as a test device to see if there's a problem with coal-damp (methane), not as a light. They still were using "naked lamps" in the mine, where that was safe.
(Ref letter 1 in Ch. 3, after 3 months use).
- The volume of the glass and gauze is optimum. If larger the heat of burning methane might heat the iron wire above read heat to sparking which would cause an explosion. (Ch 4).
- The Safety Lamp has application where lamps can start fires (App 5) such as the ship Kent owned by the East India Co.) (Wiki) where a candle set rum on fire when a keg burst killing all 364 people on board.

From Wood Library Museum (no photo):
Koehler Mfg. Co., [between 1918 and 1940?].The marking on the top can not help with the dating as it appears to have been mis-stamped, "No. 20 A" rather than "No. 201A" or "No. 203A". The late date is based on the year when electric miners lamps had generally replaced gas safety lamps.
The early date in the date range for the possible year of manufacture is based on the date that the Bureau of Mines first approved a Koehler safety lamp with a round wick (like this one), July 29, 1918.
If the shield is steel (this one is) then the early year is 1918. If the shield is made of aluminum the year would be 1919, based on the date that the Bureau of Mines approved this design with an aluminum shield.

Note these lamps tend to be named by the approval number. But that's not really the model number. In this case the approval number was mis-stamped 20_A which should have been 201A. But the model number if probably 25. This may be made using the Wolf patents after they expired or maybe Wolf & Koehler merged?
Estimate of how much Naphtha (Wiki) the font will hold. the inside is maybe 3" diameter x 1.5" high. PI R squared = 10.6 cu in. An on line calculator says that's 5.6 fluid ounces.
So will try 5 fluid ounces.
Remove cap to access fuel fill port using needle nose pliers. See Fig 9.
After pouring 5 fluid ounces into the font there was room to add more fuel, but I stopped so as not to over fill it. If you know the capacity of this font let me know.
After installing the cap I turned the font upside down so the fuel would wet the wick. Also used a small screw driver to rough up the top surface of wick. It caught fire on the first firing of the flint. Note the flint striker is an over center mechanism, so as the spring handle is turned pressure builds up and is released all of a sudden, making a strong spark. If you know of a source for 1/8" dia. flints, let me know.
While there are a number of fuels that will cause the lamp to operate it's probably the case that Naphtha (Wiki) is important in how it reacts with Methane (Wiki: Safety) and Oxygen (Wiki) so may have been the "official" fuel used in these lamps since their main purpose was to indicate the safety of the air supply, the replacement for the cannery in the coal mine (Wiki).
Unfold the spring wire handle and push up on it's shaft to raise the striker mechanism so the sparks will hit the wick. See Fig 11. I've read that some people have to strike 10 times to get the wick to light. Their problem may be that the did not push up the striker mechanism.
Adjusting Flame Height
Turn the knob on the bottom to set the flame height to the center line (i.e. a 1" high flame). See Fig 10.
Height: 10" tall. to Cap, 15" tall including hook.
Material: The waffle shield and cap are steel.
Weight: 3# 5.2 oz (3.325#) closer to the 201A than the 201. Not 201 because this one has round wick, so maybe a 201A. Not a 203A because steel, not Aluminum.
Glass Sight Lines: are 1", 1-1/4" and 1-1/2" above metal surface just below magnet poles. The wick is about 1/4" above the same reference. So the lines represent flame heights of:
3/4", 1" and 1-1/4". i.e. the center line is the nominal 1" flame.

Class 431: Combustion: / 129 to 141 involve an abrasive wheel /275 stored energy, over center release
The up-down movement of the flint mechanism was not noticed in my reading of the patent. I'm guessing the idea is to raise the mechanism (push up at the bottom) prior to sparking the flint so that the sparks are aimed at the wick, then pull the mechanism down to allow more light to shine from the flame. The double wrap wire handle can be stored below the flame height knob to keep the mechanism down.

There is provision for two different size candles (what diameters work?).
Some of these were made under contract to the U.S. Army Medical Corps (Wiki) for use in W.W.I.

This Mr. Heater model MH9BX (Home Depot) is a small propane powered space heater working on the catalytic principle (Wiki). It's California rated for indoor/outdoor use, meaning it does not generate carbon monoxide. It does however burn the oxygen from the air and so not to be used in a small well sealed space. It runs from a 1# propane bottle or with the optional adapter from a larger propane tank. Includes a piezo pilot light starter and requires no electricity.
These are made to sit on top of a wood stove. They use a Peltier device (Wiki) to power an electric fan.5544488 Self-powered heat transfer fan, Randall H. Reid, Aug. 123, 1996, - there is a bimetallic strip (Wiki) on the bottom that will lift the unit if it gets too hot (Fig 7 & Fig 8).
7812245 Self powered heat transfer fan, Randall H. Reid, 2006-12-12 - a balancing of heat differential across the Peltier device and keeping the motor and Peltier device cool enough to avoid damage. Hence the stand height separating the top of the stove and the Peltier device.
YouTube: Teardown of a self powering machine - the Tomersun heat powered stove fan has been overheated. That makes sense because it does not have the features of the Reid patent fans. -
Ebay, self powered Peltier stove fan in operation - Note the Ecofan 812AMXBX has a replacement kit for the motor. Many of the units on eBay do not seem to have enough thermal isolation between the stove top and the motor/Peltier device.
The real Ecofan brand fans go for $80 to $180, but the Chinese knockoff fans use the work Eco in the title, but not Ecofan. They also look to be poor designs.
