peei'cation of Letters ferent.

filo all whom. it' 'moy concern:

` iowa that We, Eterna E. HANCOCK fr): F. Almeno, citizens of the ales, residing at Philade phia, in county oli ldriladeiphia' and State-oit' sylrania, have invented certain new ,i which the following is a specificaention relates to improvements' in particularly designed for use i with internal combustion en- 'pecially adapted as a producer le er-:plosive mixture for engines, such used on motor vehicles, dispensing with inaryf carlourcter. urther object is to provide an ini- Atable the. operator to regulate the luixdesired proportions, and in just 'the desire/l. quantity., and which will be protected f' any danger trom back fire trom the further object is to provide an rimapparatus of this character, which .re the saine, or o 'actically the saine in all climates and weather', as sans are provided whereby the air is sub-A eed to he ,o be thoroughly dried before the hydro-carbon vapor.

'd other objects in `view, the 'sts in certain novel features struction, and combinations and ar- "ements ol'x parte as will be more :fully taller described and pointed out in the ln the accomplinying drawings, Figure 1, a diagrammatic view partly in longitudisection illustrating a preferred t'orm ol' e improvements. Fig 2, is a top 'plan w or Fig. 1. Fig. 3, is a view in cross ttiou on the line 3---23 of Fig. 1. 4l, is a 'View similar to Fig. l,.b'ut illustrating a modification. Fig. o, is ay plan View of Fig.

fl. Fig. 6,'is an enlarged ltraginontary View ful lmprorenierits in Gas-Generaed apparatus of this character', whichv hydro-carbon vapor and air in just bottom in a lower detail perspective View 'of the auxiliary air inlet disk.

1 represents a tank or reservoir, which is preferably strengthened by a partition plate 2, the latter having its corners cut away as shown at. 3 to permit free circulation of air and liquid hydro-carbon throughout the tank. The liquid is supplied to tank 1 through an opening' l in the top ot' the tank, normally closed by a plug 5, and escapes from the tank through a pipe 6 into a. chamber 7, preferably /secured to and forming a part ot' tank 1, but. having its plane as shown. The pipe is normally closed .by means of a valve-48, operated by a float 9, to maintain a .uniform level in chamber 7, Said lioat 9 being secured to an angular lever 10, the latbelow the'liquid levelin the latter, so that' the air entering the chamber is compelled to` bubble up through the liquid and become highly impregnated with the hydro-carbon vapor. This inlet pipe 13 is provided with a stop cock 14 to regulate the flow therethrough, and also with a check valve 15 to allow the flow in but one direction only, and said air pipe 13 is coiled as shown at 16 around a heating pipe 17, the latter may, if desired, serve as the exhaust pipe from the engine., so that. the air in the coil 16 will be heated before p sing into chamber 7.

ln the modlfication shown in Figs. l and 5, the structure is precisely like that above set forth, except that the air inlet pipe 13 comniunicates with an opening in the top of chamber 7 above the liquid level, and nearA one eud'of the chamber, while the outletpipe 18 communicates with an opening inthe top of chamber 7 near its opposite end, thus com-- polling the air to lpass practically throughout. the length of chamber 7 and take a large content ot' hydro-carbon vapor.

ln the preferred form shown in Figs. 1 and 2, the ters the vichaniber about the middle, but in other respects these two forms or constructionsere alike.

Lilie outlet pipe 18 above referred to is air inlet pipe 13, preferably eilprovided with a check valve 19, and also with a branch pipe 20, which We shall term the auxiliary air inlet. A suitable "lcoup ling 2l'being provided at the juncture of pipes 18 and 20. rl'hese pipes 18 and E20 are provided lWith valves or danipers and 23 respectively, which are mounted to swing Within the pipes and regulatethe opening or passage through them. Crank arms 2e and 25 respectively are secured to trunnions 26 of dampers 22 anc 23 respectively, outside of the pipes, and are connected by a link 27'. A second crank-arm 28 is secured to the trunnion 26 of damper 23, and is connected to an operating rod 29 adapted to extend to a point convenient to the operator, so-that by moving this rod 29, both. dempers 22 and 23 will he simultaneously turned to regulate the flow oit gas and the inlet ofl the auxiliary air supply.

@n the upper end of pipe 20, a cap 30 is provided in its upper end with a circular.' series oi3 perforations 31, with which the periorations 32 in a disk on top of cap 30 normally register. This disk 33 is made with a. central opening 34e adapted to receive a rod 35 secured in cap 30 and turn freely thereon. The upper end of this rod 35 is provided with a nut or head 36, and a` coiled spring 37 is located around the rod 35 and bears at .its respective ends against head 3G and disk 33, so as to normally hold the latter 'tight against the top .of cap 30. An angle or crank-arm 38 is made integral with disl-r 33, is connected to an operating rod 39, is also connected to one end of a spring l0, the other end ot said spring being secured to the'cap 30, so as to normally hlold the arm 38 in contact with a pin l projecting outwardly from the cap 30. This pin 4l limits lthe rotary movement of the disk in one direction, While the rod 39 is adapted to he moved by the operator to turn disk 83 and move the perforations 32 in the disk out of register with the openings 31 in cap 30, and hence shut oli, or partially shut oli the auxiliary supply of air. Should there be a hack fire from the engine, the pressure Withinv pipes 18 and 20, if the disk 33 is turned so as to close the o eriing 3l, will move the disk 33 longitudina ly of rod 35, against the action of spring 37 to permit the hack lire and pressure to escape Without doing any injury. The pin @il is .of suiiicient length to allow the necessary movement oit the disk Without escaping from its engagement with the pin.

.The operation is as follows: Atmospheric air is drawn in through pipe 13, is heated in the ,coil 16 by means of the exhaust pipe 17 and after mixing vvith the vapor in chamber 7, flows through pipe l@ whereit is joined Ahy Vthe air through the `auxiliary pipe 20S The operator can hy means of rod 29 and the parte above enplainedpturn the dempers 22 and 23, so as to entirely c lose pipes 18 and 20, to shut oli' the explosive charge to the engine, and can open said pipes, so as to allow just the desired quantity of explo sive mixture to flow to the engine. Ii .he desires to change the proportion of the mixture, that is, a greater or less amount of air,

he operates rod 39 to turn'4 disk 33, and close i therefore Cget by check valve 1,9 and into the liqiiid hy ro-carbo'n. n Various slight changes might be made in thel general form and arrangement oic parts described Without decparting from our inven` tion, and hence We o not restrict ourselves to the precise details'set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall ,Within the spirit and scope of the claims.

In a gas generator, thecombination with a. generating chamber adapted to contain liquid hydro-carbon, of an `air inlet pipe communicating Withsaid chamber, al gas outlet pipe communicating with said chamber, an auxiliary air inlet pipe coinmunicatingwith said gas pipe, a combined air inlet and pressure relief valve on said auxiliary air inlet pipe, dempers in said .auxiliary air inlet pipe and said gas pipe,
