This invention relate t0. a carbureting p osive engines', ond is `more especially 1.11- lThe principal object 'is to provide a devioe`ofthis character that will automaticallycontrol and regulate the admission and nuxin of the ,explosive charge. l l .n carrying out thc objects of' this inwontion, means arc'cm .loyed which will simul-y taneously, control t proportions to lsecure the greatest` eilicieney. A practical embodiment of the invention islillustmted in the accompanying drawings.

into manipulated by disk l2. The valve C bein in its lowest position, the collar 20 is adjusted to leave a space 21 between it and the underside of the end disk 12. The spaces 19 and 21 a1eprc cau 6 tionary as against back explosions and when one occurs the pressure is relieved through these passages and injurious effects avoided. lVhen the engine is in motion some air will always pass up through the spaces 19 and 21 the mixing chamber, but this is provided as a part of the supply only. lVhen the valve is raised, the space between the end disk l2 andthe collar-5.20 is'increased. Thisjcollar is set by the maker; of the car- 15 bureter to determine the initial flow of air through passage 19. The inflow of air at -thispoint is, of course, limited by the size of passage 19, while the flow through ports- 15 has a wider range of variation. v

valve rod 22 extends1 up through the A tubular post 18 and has a needle valve 23 formed on the upper end thereof. The lower en'd of rod 22 passes through and is threaded in a part of a 'stuiiing box 24. and is means of the handle end 25 in adjusting the position of the needle valve. The gaseous element.`enters the apparatus through a tubular `connection 26 and passes up through the space 27 between 30. the valve rod 22 and the surrounding wall of the tubular post 18 into the; mixing chamber 16.

A bridge 28 is mounted on the end disk 3-5-12 of valve C and arches over the upperend of the tubular,.post and the needle valve. "The'upper end ofthe post presents a conical surface 2 9 and the bridge is provided in the underside with a corresponding seating 1` cavity 30, forming a downwardly deflecting stopper which, whenthe valve C is 1n itsclosed position, engages the upper end of the tubular post and closes the passage past the needle valve and when the valve is raised directs the hydrocarbon. downwardly and laterally into the currents of air. Thus the valve C is supported from the upper end. of the tubular post in a suspended posltlon when the engine is at rest. VBy this arrangement combination valve'C with its central gas port and its central and circumferential air ports automatically controls and pro- 'portions the admission ofboth the airand gaseous elements into chamber 16 1n accordance with the working demand 'of the engine. The valve C will ordinarily avitate into its closing'position, ,but is asslsted by-comT jaanion'springs 31 coiled on compamonrods 32 inserted inthe lower ends vof two ofthe valve ribs and located at opposite sides. The nuts 33 provide means'for adjusting the tension of said springs. When the gaseous element flows into the mixing ychamber 1t.1m

r pingesagainst the underside of the. bridge and is forced out laterally indifferent direc- 35 tions.v The air as it enters into the mixing chamber 16 through the center port 19 and the` circumferential ports 15, entirely surrounds' thein'comin gaselement so that a thorough mixture o ing the explosive charge is effected. The' inner circumferential surface of that portion of the casing inclosing the mixing chamber is provided with a number of inclined vanes 3l and acts to impart a spiral whirling motion to the elements forming the explosive charge and assist in the o eration of mixing. The shoulders 35 formed on the vanes 34 limit the up or open movement of the valve In practical Working. the valve has a very sensitive vibratory action and instantlyl responds to the slightest variation of speed in the engine and admits mre or less of the gaseous and air elements as required.

A throttle valve 36 is mounted on -a stem 37T and locatedin the passage 38 .in the casing part A which connects with the tubevor pipe. conducting the explosive charge into the engine cylinder. A crank arm is mounted on the outer extended end of stem 37 and 'provides 'for the operative connection with the mechanism under control of the operator. 4
