is a vertical sectional view ot' a portion ot the. earbureter showing' the meanstor supporting` parts of the pump therein. F 4, is a plan view of the air supply regulating means or lower portion of the. device. Fig'. 5, is a fragmental View ot a portion ot' the body easing orI cylinder and apart of the mixing chamber showing a moditieation in the construction of the means for the passage of air from the. body casing to the mixing.,Y chamber. Fig. G, is a. fragmental plan view of a portion of one of the valves of the-air chamber.

Lilie numerals oi` reference, refer to correspending;4 parts throughout the different. views of the drawings.

The reference numeral l0, designates the on its upper end an out-turned annular for securing the casinglhpt the mixing chamber on' said flange. As shown in F l, and 2, ofthe drawings,.the body or cylinder 10, is provided within its cartity with a receptacle 1.5, which is preferably substantially bell-shaped as shown but ma \r be of any desiredt'ornl and is held at a distance from the inner walls of the easing -or cylinder l0, by means of lugs 16, which unite the two parts l0, and la, about midway between their upper and'lower ends. T he said parts may be formedv integrally it desired, and one'of'the lugs or extensions 1G, is prtwided in its outer portion with a screw-tln'eaded opening` 17, from which a port 1S, leads into the Cavity of the receptacle l5, or inner easing. which has its upper portion contracted and provided with a sere\\'threaded open- 'the pump cylinder for thepurpose to be presently explained. Leadlng from the upper end of the cavity flange lfl, provided with a series ot' openings` 12, for .the reception ot' screw-bolts t3, used llt".

21,'in the pump cylinder is a channel 23, which terminates at its upper end in an. enlarged opening 24, formed in the upper end of the cylinder 20, and provided with in-.

ternal screw-threads to engage screw-threads on the lower portion 'of a spreader 25, t'or the gasolene, which spreader is preferably conical inshape and has a peripheral upturned iiange 26, to form a receptacle for the retention of a quantity ot' gasolene. The spreader 25, is provided in its lower portion with a vertical opening 27, in which is located a ball-valve 28, normallyseated in the upper end of the channel 23, and held in vits seated position by means of a spring 29, located in the opening 27, and resting at one of its ends on said ball and at its other end against theupper end of said opening. Communicating with the opening 27, and extended through the 4apex of the spreader 25, is another opening 30, which forms a seat for a needle valve 31', used for regulating i the flow of gasolene to the mixing chamber.

Communicating with the opening 27, and extended to one lside thereof and throiigi the lower` portion of the spreader 25, is a channel 32, which communicates with a channel 33, formed in the upper portion of the pump cylinder 20, and extended downwardly therein to a point' below the upper end of the casing or receptacle l5, at which -point it communicates through an opening 34, with the cavity of the said receptacle. Seated in the upper portion of the opening 33, is a ball-valve' 35, which is held in its seated position by means o t' a spring 3G, which rests at one of its Aends against the bottom of the opening 33, and at its other -end against the ball-valve The lower portion ofthe base 19, of the pump cylinder is provided with a vertical opening 37, which is internally screw-threaded to engage screw-threads on a plug 38, which is provided in its upper end with an opening 39, having a reduced channel 40, extended from the lower part thereof, out through one side of the plug and communicating with a port 41, formed in the side of the pump cylinder just above the base portion thereof.h

Leading from the upper end of the opeuing 37, is a channel 42, which communicates at its other end with the upper portion of the cavity 21, for the piston or plunger of the pump. 'Located in the-opening 39, and seated in the up'per end of the channel 40, is a ball-valve 43, which controls the ow of l' gasolenc from the receptacle 15, into the cavity of the pum cylinder. Secured on the lower ortion o the body casing or main cylinder l', is a eup'44, which is provided in its walls with a series of openings 45, for the passage of airthereinto, and has in its lower portion a series of openings 46, controlled by gravity valves 47 which openings are' also for the. admission of air. As

shown in Fig. 1, the piston or plunger 22, is extended through an opening in the bottom et' the cup 44, and has its lower end screw-v threaded and provided with nuts 48, to regulate -its stroke. Rotatably fitted. in the cup 44, is a ring 49, which is provided with a series of openings 50, adapted to register with the openings 45, in said'cup, yet which may be turned out of register therewith or partially so by means of a projection 51,

which is secured on the ring 49, and exor plate valve 56, which rests on the top of the casi ng or cylinderllO, and has'on its lower Surface an annular flange 57, which ts snugly in the cylinder 10, and is provided with openings y53, for the passage of a1rl therefrom. Thus it will be seen that the plunger and valve 56, are connected together by means of the rods 54, and that said parts will move in unison. l

Located on the flange 11, of the, cylinder or casing 10, is the casing 14, of a mixing chamber 5E), which casing will be secure in place by means of the screw bolts 13, as before stated. The lower inner portion of the casing 14, fits snugly around the valve 56, yet .so-as to permit ot its vertical movement, for it will be understood that said valve is provided with a central opening 60, to lit around the upper portion of the pump, cylinder which is rigidly held in place within the casing. 15, by means of its screw engagement therewith, as well as by means chamber. Leading from the upper portion ot the casing 14, is a conduit 63, which mayr be suitably connected to the engine (not' shown) and which may be providedv with a.

' damper G4, of any well known type to regulate the passage of the mixture of air and' gasolcne from the mixing chamber teltheV engine. Mounted in the upper portion of the conduit 63, in any well known W`a'y .is a needle valve 31, whic spreader 25, and has on its lower portion a 4battle 65, for the gasolene and'air as theyr is adapted at its lbwe'r.l

end to open and close the port 30, in the 35, ports from the engine, or an explosion 4in the mix- .'ing e hz u1 1b,er.. v n 1 f Secured fin; =the 'opening-17,fthe j casing or cylinder is a ilting'GS, which is pro- 10 vided with' an inlet channel (39,.co1n'municating with the port or opening 1S, for`the supply -`*of gasolene to the receptacle 15,

which channel may have communication through a'pipe 70, with a supply of gasolene (not sl1own). The fitting 68,' is provided with a pin'valve 71,- adaptedto be seated inflhe channel-69, -for regulating the supply' of gasolene to' the receptacle therefor. 1 Intersecting the channel 69, is an opening4 72, iny which )is ttcd'a tube73, which has at its upper end a v sieve 74', Aof wirergauze or other,suitablemateriali() strain the gasolene as it passes through the vcha` r m el69, into' its receptacle. .;The ndof-'the tube 73, is. clesedA byimnnsf e7 gaging thedoiver endfof th vlrtension- 76, formed on the-Qttingtand' ov'nrnunicatmg 'With-'fthe OPllP "I n Fi wat he" dreumes 1S v-Sh ireffl modification in' the'constructionigf the uppe'. bto oftll-ie exklindemorcasing 1 0, and. in

It Willbe observed-that in this lnoditied' construction the openings in the flange 57, of the valve are omitted.

The operation of the device is as follows Gasoleneor other hydrocarbons is sup lied to the receptacle 15, through the channe s 69, of the'itting 68, and through the port 18, of said receptacle, when through the suction or operation of the engine .vtl1e valve 56, will be raised within the mixing chamber until the openings 58, are placed incommnnieation with the lower portion of said chamber, at which time, air will pass through the ports 62, and lbe discharged directly above the spreader 25. In the upward movement ot the valve 56, Iit is apparent that the plunger; 22, being united thereto.v will be caused to rise in its cavity and thus force gasolenc therefrom through the channel 23, and port 30, in the spreader. As soon as ihe suction 69 in the mixing` chamber is overcome, the

springr 78. which is interposed between the valve 56. and the easing 14, will force said eration gasoleue will be drawn through the 976,881 :incite:
