Gas, for example compressed oxygenoi" air. enters on the side ofthe carbure-ter through the nipple or hose connection D and 'thence passes downwardly throughthe pipe l), which is' coiled helically, finally entering the lower compartment C throughhthc opening- I". The compartment C forms, a condensation or drip chaniber. From the compartment C the gas passes upwardly '-hiough the openin` G and the coil H which' terminates at its upper end in the pipe Ileading to a valve head J. l" rom the valve head J a 4pipe K leads to the bottom of'the upper compartment-B of the carburetor. -The ac- -cess of gas to the 'pipe K ifs controlled bythe needle valve L having a suitable thumbscrew M. The vvalve head J- also connects with another needle valve N which is provided with a hose ni pple and is adapted to be controlled by the thumb-screw 1 The upper vcompariment B of the carbureter is provided at its upper end with'a cover R adapted to be screwed onto the top S. A gasket :fir washer of lead or other suitable ,matic-'rial is preferably fastened between the.

As the gas generated in such carbureter. is very inflammable, it isdesirable to have an explosion arrester between the -outlet and the tube leading: to the I burner. This is conveniently provided by cut-from 'wire screens. the bottom of the cavity in the plug is closed with a disk of wire screen or perforated' metal', as'shown atY. Topreveut `theab''.

it should be understood that it is intended tobc usedwith compressed air, oxygem'orj other gases .which are supportersot` combustion, and hasf'or its function the saturation or carbureting of such gases with the volatile vapors -ofintlannnable liquid soasto generate an inflammable gas. Carburetors of this type are preferably used 4in connection with oxygen gas, which-may be drawn from cylinders of compressed oxygen or from automatic oxygen generators.v lVhen connected by tubing to the oxygen supply 'and as soon as the valve; on the oxygen apparatus is opened 'gas [lows into the pipe E to the coil E', the condensation chamber C and the coil H to the valve head J, vfrom which it may be admitted by the needle valve L to the pipe K leading to the bottom of 'the upper compartment B which has previously been filled with the liquid lo the level of the outlet plugo. Upon passingl upthrough the absorbent material' to the outlet cock'Q, the oxygen or air becomes carbureted or saturated so as to burn readily at 'the orifice' of a suitable burner, as' for cxample, the tip of a1 ordinary calcium light jet.- This burner sl'euld beef a type adaptt receive a hollow plug ll" on which is mountl and a supporter of combustion such as oxy- 'densation mayl be' withdrawfn 'from timeftok erlftolbuin such mi,lture of inflamn'mble Patent-@ 1 Dee. 30, 1913.

in use the inlet nipple D 'of the carburetor gen or .atmospheric air. Thev outlet hose nipple O of the needle valve N for the un. carbureted oxygen is connected to the inlet of the burner which is adapted to receive the gas which is the supporter of combusoxygen t0 arrive at the burner and there mix j with the carbureted gas in sufficient proportion to? cause practically complete combustion, so that the flame is of the highest temperatu're attainable considering the caloritic' value of the liquid used and its volatility. A f

Thistype of carbureter is V'adapted to be `used i'nconncction with burners consuming two gases or ini connection with a b urner adapted to consume a single gas after it has become carbureted with the vaporot` the liquid usedr lVhen used in' connection with automaticjoxygen 'generators which generate gas'froin the reaction between compounds 30 such"asf.peroxid of sodium and water, there 'gis a certain amount of Water vapor carried from vthe gen crateri-.Which would ordinarily tendto collect in the-chamber containing the absorbent material. l In the carburetor here-- I in described this vapor of water or other liquid, which may contaminate the supply of oxygen or air,condenses in the coils E and H and is deposited in the condensation chamber C. This action is stimulated by .the cold 40 produced by the rapid vaporization of the liquid which. in practice causes a very Jmarked drop in temperature within the carbureter.

If at any time it becomes desirable to change the absorbent material or filling of the carbureter, the cover R may beremoved, which exposes an opening sulliciently large for that purpose. For the purpose of lilling the carburetor with liquid it is only necessary to remove the hollow plug WV, which is provided at its upper portion with a hexagon c.

It is obvious that many forms of this invention maygE-be embodied without using the exact construction shown.

I claim and desire to obtain by Letters Patent the following:

l. A carbureter comprising a carbureting cha1nber,a condensation chamber separated therefrom, a pipe for gas to be carbureted leading tortuouslythrough the carbureting chamber to the condensation chamber, a pipe leading from the condensation chamber and having two branches, one branch delivering outside the carbureter and having a. controlling valve for @ducting gas uncarbureted, and the other branch opening into the carbureting chamber below the normal liquid level therein, and a valve for controlling the last said branch.

2. A carbureter comprising a carbureting chamber, a condensation chamber separated therefrom, a pipe for gas to be carbureted leading through the carbureting chamber to the condensation chamber, l a pipe leading 75 from the condensation chamber within the carbureting chamber and having two branches, one branch leading outside the carbureter and provided witha valve foreducting gas uncarbureted and the other opening into the carbureting chamber below the normal liquid level therein. I

3. A carbureter comprising a carbureting chamber, a coil therein connected to receive gas to be carbureted and in which the gas is cooled, a condensation chamber to which the said coil delivers, and a. pipe for conducting the gas from the condensation chamber back iiito -the carbureting chamber and delivering it nea-r the bottom thereof, 'and a valve 90 for controlling the Aflow of such gas. .A

4. A carbureter comprising aycarbureting'; chamber, a coil thereinconnected to receive. gas to be carbureted and in which the as is cooled, a condensation chamber to whic the said coil delivers, and a branch pipe and valve for leading od some of the gas'after cooling and condensation and Without carbureting.

5. A carbureter of the Aclass described, comprising a chamber having carbureting and condensation compartments, absorbent Inaterial placed Within said carbureting com `A partment, a condensation coil within the carbureting compartment and in communication with the condensation compartment, means for conducting the flow oi" gas from ,condensation compartment to the bottom of said carbureting compartment, a valve controlling and regulating said flow of gas to the bottom of carbureting compartment and a secondary connection and valve for con-A trolling the flow o'the uncarbureted gas or other supporter of combustion.

In testimony whereof I have signed this specification in the presence of two subscribf ing witnesses.
