SPECIFICATION forming part of Letters Patent No. 651,017, dated June 5, 1900. A Application filed September 26, 1899. Serial No. 731,759. (No model.)

To all whom, t may concern:

Be it known that I, ANTONIO L. N AvoNE, a citizen of the United States, residing at Oalistoga,countyof Napa, State of California, have invented an Improvement in Hydrocarbon-Gas Generators; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus for generating explosive vapor from suitable hydrocarbon liquid, and mixing the same with air in proper proportions for the purpose required.

It consists of an arrangement of apparatus and devices by which the desired result may be obtained, and which will be more fully explained by reference to the accompanying drawing, in which the ligure is a vertical section of an apparatus adapted for the purpose.

The generator consists of an exterior closed case A, which is here shown as supported directly upon the exhaust-pipe B, which conveys the waste products of combustion from the exhaust of an explosive' engine in which the gas is to be used. The products of combustion passing through this pipe are discharged at any convenient point, and the heat produced by their discharge through the pipe is sufficient for the purpose of vaporizing the liquid hydrocarbon. I

The generatorcase A is removably supported upon the pipe by means of a collar or support a, fixed upon the pipe at a suitable point, and the bottom of the generator is fitted to rest upon this support.

The cap or cover of the generator is retained in place bya nut a', which serves when screwed down to hold the generator firmly in place upon the pipe. By removing the nut and disconnecting pipes it is possible to remove the generator for any purpose.

W'ithin the generator is a spirally-disposed channel C. This channel is made, as shown, in sections by takipg channeled steel about an inch, more or lss, in width and having upturned flanges which may be about oneeighth or three-sixteenths of an inch high. This channeled steel is heated and coiled closely around the pipe B, preferably being closed together when it is coiled, so that. any irregularities in the curve may be straightcned by hammering the superposed coils, one

sage through it of the hot vapors, and if the coil is cast or formed as a part of the pipe the oil will be too much heated; but by making'it separate from the pipe this excessive heating is prevented. Below the coil and surrounding the pipe Bis a pan F, into which the lower end of the spiral or coil trough discharges.

The materialto he treated, which may be heavy unrectilied petroleum or any of the lighter products, or a combination of the two,

is contained in a receptacle, as shown at E,

and a pipe E connects with a valve-chamber- E2, into which the oil is first delivered. The

flow from the chamber E may be controlledl bya cock, as shown at e. If two qualities of material are to be used joint-ly, the second quality may be furnished through a pipe EB, having a controlling-cock e', so that the pro'- portions of the two are properly controlled, and the material unites in the pipe E and flows into the valve-chamber E2.

E4 is a valve; here shown as being pressed downward bya springE5,which normally holdsl it closed against its seat with a certain tension.

The stem of this valve extends up through4 vthe top of thevalve-chamber E2 and is there connected with an arm E6, and this arm is connected bya wire, rod, or other device E7 with a governor E8, of any suitable description, driven from the engine. This governor acts, when running at slow speed, to hold the connection Ev7 and the arm E6 down, thus compressing the spring E5 and allowing more of the oil to flow through the valve-opening, and

4when the engine runs at too high a speed the movement of the governor will release these parts, allowing the spring to act and close the valve to a greater or less extent, as required. The governor regulates the flow of gas to the engine and also the supply of oil to the generator, so that the supply of oil is always proportioned to the amount of gas which the engine is using. Thus if the load on the engine is regular and steady the flow of liquid may be adjusted and there will be little or no variation; but it the load is variable this construction automatically regulates the su pply of oil and also of gas at the same time. Thus when once adjusted to the work which the engine is to perform no further atten tion is necessary. From the valveehamber E2 the liquid passes by gravitation and is delivered by a suitable discharge-nozzle D into the upper end of the spiral trough C, through which it ows around the exhaustpipe l5, and being in contact with this pipe the heat will vaporize all or almost all of the liquid before it reaches the bot-tom. Any portion which may remain unvaporized at the lower end of the spiral will be discharged into the pan F, where it is still subjected to heat l'rom the pipe B to complete the vaporlzation of all that is capable of being so vaporized. Any surplus will overiiow from the pan and fall upon the bottom of the case A. This bottoni is made concaving upwardly in the center, and the periphery being lower than the center any overflow will pass to the outside and may be discharged through a drain-pipe G. In order to supply air to be mixed with the vapor thus produced, an air-supply of any suitable character maybe brought to the apparatus through the pipe I. From this pipe a pipe Il discharges into the upper part of the generating-chainber, and the air and the vapor produced in the chamber Will be mixed in proportion depending upon the supply of air furnished. This supply is regulated in the. first instance by a cock I', and, if desired, another cock may be iixed in the pipe II for -the same purpose.

L is a pipe leading to the engine, and Is. is a branch bringing the mixed air and vapor to the pipe L, into which it discharges. The pipe K 'connects with the generator-case A at any desired point, and the gas from the generator is thus led through it and the pipe L to the engine,where its ad mission is controlled in the usual manner by valves. (Not here shown.)

In order to vary the proportions of gas and air after they have left the generator, I have shown a connection between the supply-pipe I and the conductingpipe L, and by means of a cock J any desired amount of air may be introduced into the pipe Lto mix with the explosive compound already delivered thereto from the generator. In this manner I am enabled to control the explosive proportions of the gas very closely. The connection between the pipe K and the generator is made through the valve-chamber, containing av hinged or other valve O, opening outwardly from the generator for the flow of gas, but adapted to close the passage in case of any explosion or pressure from the engine which might injuriously affect the generator if allowed to enter it. Connected with this valvechamber is an outwardlyopening springpressed valve P, which serves as a safetyvalve and which will be opened against the pressure of its spring in case of any unusual pressure from the engine.

The top of the generator-case A has perforations made in it, as shown at R, and upon this perforated top is a rotatable plate S, having corresponding openings or perforations R'. This plate may be turned so that the openings R coincide with those shown at R, in which case air may be admitted to the generator through these openings in case more air is required than is passing through the pipe H. The constant action of the engine serving as a suctionpump to draw the vapor from the generator to itself will also draw air in through any openings or passages which may be provided for the purpose. An arm or handle T is fixed to the turuable plate S, and by moving this the plate may be adjusted to suit. This plate is held in close contact with the top R by means of a spring U, and the tension of thisspring is adjusted by turning the nut A' down more or less. Incase ot any pressure within the generator greater than is desirable this pressure will either escape through the openings R R when they are coincident, or when the plate S has been turned so that these openings are closed it acts as a safety-valve, the pressure overcoming the tension of the spring U, and lifting the plate S bodily so that vapor can escape through the openings R R.

Sufficient heat may be applied through the tube B to start the apparatus by means ol' a heater of any desired description applied within the pipe B below the generator; but aftersnffioientgas has been generated to start the engine the exhaust products therefrom will be su tlicient.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
