This invention relates to apparatus for obtaining a supply of air or gas, carbureted and containing hydrocarbons, for illuminating purposes and at the same time to supply hydrocarbon fuel to'a carburetor of an en- The invention consists incarbureting' apparatus for air or gas comprising a fuel reservoir from which fuel passes to a chamber in which the air or gas is carbureted and from which a passage leads to the engine carbureter so that the fuel is led away from the carbureting chamber to the engine carbureter, its place being taken by a fresh supply whereby the composition of the fuel in the carbureting chamber is kept substantially constant.

The invention further consists in the improved apparatus hereinafter described.-

The accompanying drawing illustrates diagrammatically one form of the present invention, the chamber a, and the reservoir n, being shortened for the purposes of illustration.

lln carrying the invention into eect according to one form there is provided a reservoir (1., preferably of cylindrical form having two ends 6 and c which are flat or very slightly convex. The lower end 6, supports at its center a rigid rod d, screwed into a Y fitting e, fixed in a fluid tight manner to the end 7). The lower end of the rod 0? has a notch f to allow of the introduction of a screw driver therein, for the purpose of adjusting the rod in the fitting e. A cap 9' serves to protect the end of the rod and to insure a fluid tight joint. The other end of the rod d carries a valve head k, the seat 1: of which is fixed in a fluid tight manner to the cover 0 of the chamber. This valve is covered by a cap k which serves to admit the air or gas to be washed and carbureted. The seat of the valve 2' extends downward in the form of a tube Z which is fixed to the cover a and is guided at its lower end by the fitting e on which it can slide freely. At a short distance from the bottom of the chamher, the tube is perforated with holes m distributed uniformly around the tube.

Ata certain distance from the upper end of the reservoir there is arranged abafie constituted by two-plates t t fixed, one to the wall of the chamber, and the other'to the tube 1. At 0 there is a safety valve for preventing too great arise of pressure in the interiorof the chamber. It is assumed that the chamber a is filled to a certain level be-- low the plates t with the carbureting. liquid.

The operation of the apparatus is as follows-:The air or gas to be carbureted is supplied by a pump or other suitable means (not shown) through the cap 7;. at a certain pressure. It passes through the space between the head h and the seat 2" and thence takes its course between the rod 0'. and the tube Z to the level of the holes m. 0n issuing from these holes it bubbles up through the liquid and reaches the upper part of the chamber, whence it passes away through the it is desired to maintain to the top of the tank a as shown. The pressure in the chamber a is above atmosphere by an amount equivalent to the difiere'nce in levels of the liquid in the chambers m and a. If the pressure rises sulficiently to force the level in the chamber down to the point at which the pipe enters that chamber, there is an immediate'flow of fuel from the chamber m so that the level is maintain in chamber a at the level of thepipe p as shown in the drawing. The operation of the chamber a in order to maintain a constant pressure in that chamber is as follows:

Assuming that for some reason the pressure inside the chamber (1 increases then the two ends b and 0 will undergo a proportionate elastic deformation and the two fit- I tings z and'e will have a tendency to move conduit 9 and cock at. The conduit 9 is led is connected to the main, fuel reservoir n and c apart sufliciently to close the valve 2' completely. Therefore, if the pressure .of

the air or gas to be carbureted is always ".greater than that limit, the internal pressure will remain constant and will approxi:

- mate the more closely to this limit'the greater the surface of the valve, because then on the least drop of pressure-in the reservoir below this limit the valve will open and allow a further quantity of air or gas 'to pass into the chamber a, which quantity will tend to bring back the pressure to what it 'was previously.

This apparatus being intended for use on motor cars, it is provided at its lower part with two connectors i and 8, the connector 8 feeding'the enginewhile other connector 1' is adapted to be connected to the carbureter 'of the engine. The connector 9 can be connected at will by the cocku tothe lamps for lighting. -Under these conditions let it be assumed that through is there is admitted compressed mixture air, or exhaust gases from the engine cylinder, or any other gas supplied by the engine or from an independent s'ource. The level of the liquid will sink to the level of the connector 1), irrespec- .tively of the level in the main reservoir n of the motor provided that the latter is fluidto the depth between the holes m, and the level of the liquid so that the gas is regularly 'carbureted and washed by bubbling up through a liquid column of constant height and concentration which 1s contmually being renewed.

- Having'now described my invention, what I'claim as new 'and desi're' to secure by Let ters Patent is 4 I Means for supplying both combustible gasand liquid fuel comprising in combina' tion a fuel supply tank, a carbureting chamher, said carbureting chamber having flexible ends, a valve stem connected to one end.

of said chamber, a valve box secured to the other end of said chamber, a valve seat formed in said valve box, a gas supply pipe leading into said valve box, two pipes conmeeting said fuel supply tank with said carbureting chamber, one-of said pipes leading from the bottom of said tank tothe bottom of 'saidchamber, the other of said pipes leading from the top of'said tank-to an intermediate point in the height of said chamber, a guiding tube fixed to the top of said carbureting chamber, said tube having-perforations below the level of the 'li uid in said carbureting chamber, as and or the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two' subscribing witnesses.
