SLPEGIFEGATION forming part of Letters Patent No. 697,80 7, datecl April 15, 1902. Application filed June 28, 1901. Serial 110.66.385. (No model.)

To all whom it may concern:

Be itknown that I, CHARLES LINCOLN CHAM- PION, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Carbureters, of which the following is a full, clear, and exact description.

The invention relates to the generation of gases by the use of hydrocarbon liquids, such as gasolene and the like; and its object is to provide a new and improved carbureter for use in dwellings, factories, &c., andarranged to furnish asupply of gas of uniform richness and in the quantities required for immediate consumption and no more, so as to obviate the storage of gas prior to its actual consumption.

The invention consists of novel features and parts and combination of the sa1ne,as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying; drawing, forming a part of this specification, in which the figure is a sectional side elevation of the improvement.

A suitably-constructed generator-casing A is provided at its top with agas-outlet pipe B for delivering the gas to the several burners in the dwelling or other place in which the gas is to be burned. The lower portion of the generator-casingAis filled with loose material G such as sponge, cotton, excelsior, sand, ground coke, &c.and on top of this material stands the hydrocarbon liquid D at a predetermined level, so that the material C is at all times submerged. The hydrocarbon liquid, such as gasolene, is discharged into the generator-casing'A by a supply-pipe E, openinginto the generator-casing Aa distance above the top of the loose material C, and the said supply-pipe E is connected with a reservoir F, having a filling-plug F and elevated to such an extent that the lower portion of the reservoir is approximately on alevel with the predetermined level of the liquid D in the casing A. By the arrangement described the hydrocarbon liquid flows by its gravity from the reservoir into the generator-casing A. A shut-01f cock E is arranged in the pipe E near the reservoir F, and on the discharge end of the pipe E is arranged a valve E ,controlled by a float G, rising and falling with the hydrocarbon liquid D, contained in the generator-casing A. By this arrangement the predetermined level of the liquid D is maintained constant in the casing A.

Into the loose material C discharge the airsupply pipes H, H, and H located one above the other and extending through the wall of the generator-casing A to near the center of the inside thereof, as is plainly indicated in the drawing, and each of said pipes is provided with a cock H for opening or closing any one or all of the pipes whenever desired. The pipes H, H, and H are connected with the lower leg of a U-shaped discharge-pipe I of an air-pump J of any approved construction. The pipe I rises above the top of the generator-casing A, so that it is impossible for any liquid contained in the casing A to pass up the pipe Iinto the pump J. A'checkvalve 1 is arranged in the lower portion of the pipe I to prevent a backtlow of air into the pump J.

The upper portion of the generator-casing A is connected by an overflow-pipe K with a closed safety-tank L, so that in case the liquid D should rise in'the casing beyond its predetermined level then the liquid will flow through the pipe K into the safety-tank L, and

consequently will not rise in the gas-outlet pipe B.

A circulating connection N, preferably in the shape of a pipe, connects the upper portion of the casing A with the lower part thereof to allow the liquid D to circulate in the loose material C at the bottom thereof to insure a proper mixing of the inflowing hydrocarbon liquid with the depleted one already contained in the casing and the loose material.

The operation is as follows: When the valve .E and any one of the valves H are opened and the pump J is set in motion, the air is forced by the pump J through the pipe I and one, two, or all of the pipes H H H into the loose material C, which causes the air to be divided into very small parts, which rise bubble-like in the material C and through the liquid D, standing above the loose material (1. The air during its passage through the material 0 and the liquid D becomes enriched, forming a hydrocarbon gas, which passes by the pipe B to the place of consumption at the burners in the house or other place. When it is desired to make the gas exceedingly rich, the valve in the pipe H is opened, the

pipes H H being closed, and when it is desired to decrease the quality of the gas the valve in the pipe H is opened, the valves in the pipes H H being closed, and a further decrease of the quality of the gas can be made by using the pipe H, the valves in the pipes H H being closed, the quality of gas depending entirely upon the depth of the airin'let pipe in the loose material C and the course the air is made to travel within the submerged loose material 0. The course of the air can easily be controlled by placing sheet metal or other suitable substance to guide the air in its passage through the loose material C.

It is understood that the loose material C- retards the progress or movement of the air through the hydrocarbon liquid D, so that the air passing in small quantities into the generator-casing A requires about the same time to pass through the loose material C and the liquid D as larger quantities would require, and consequentlya different quality of gas can be'obtained by using the pipes H II H as stated above.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A carbureter having a generator-casing containing loose material, a hydrocarbon-liquid supply for the said casing and havingits inlet above the said material, to completely submerge the latter on filling the casing with the hydrocarbon liquid to a desired level, means for maintaining the liquid at the desired level above said loose material, andan air-supply discharging into the said loose material below the top thereof, to divide the air into small parts which, in rising, pass through the hydrocarbon liquid into the upper portion of the casing, as set forth.

2. A carbureter having a generator-casing containing loose material, a hydrocarbon-liquid supply for the said casing and having its inlet above the said material, to submerge the latter on filling the casing with the hydrocarbon liquid to a desired level, avalve controlling the admission of the hydrocarbon liquid to the casing, a float arranged in the casing above the loose material and connected with the said valve, and an air-supply discharging into the said loose material below the top thereof, to divide the air into small parts which, in rising, pass through the hydrocarbon liquid into the upper portion of the casing, the said air-supply having a plurality of valved discharge-pipes opening into the loose material one above the other, as set forth.

3. A carbureter having a generator-casing containing loose material, a hydrocarbon-liq uid supply for the said casing and having its inlet above the said material, to submerge the latter on filling the casing with the hydrocarbon liquid to a desired level, an air-supply discharging into the said loose material below the top thereof, to divide the air into small parts which, in rising, pass through the hydrocarbon liquid into the upper portion of the casing, and a circulating connection for connecting the hydrocarbon liquid in the easing with the lower portion of the loose material, to allow the liquid to flow by gravity into the loose material at the lower part thereof, as set forth.
