To @Z3 whom, t may @ono/Wn:

Be .it known that we, HENRY Looms and CLEMEnT Vv". Bonino, oitizeiis of the United Saes, residing a Bradford, in tile. county of iik-Keen and State of Pennsylvania,l have invented certain new and useful lniproven'ienis in Governors for Gasslin gines, of which the following is a specification', reference being had `therein to the aoeompanving drawing.'

@or invention rela les to iniprovenieni'zs in governors for gas engines.-

The obj/eet oi our invention .is o provide a governor of this character ,in which the supply of both die air and to elle engine eyiinder is gnlated so lia: no ma ,ter what. speed 'die' engine is` running, the proper miiiure Wii ne snpgiied to the engine cylindern Anolier object oiC our invention is to provide a more simple7 elieap and effeoive governor of liis character in which the speed of 'lie engine may be more readiiy governed and having certain details hereinafter more fully described.

` ln the accompanying drawingwiiignre l is a verienl sectional vieiv. of an engine Cyl inder showing our improved governor ai."- taelied oeretfr E2 is a horizontal seeionai vievf taken on the line 2---2a of Fig. l. ln speed governors for gas engines, vv'nere iiegas only is reduced and the foil ammini: of air is supplied the mixture is noi; as rioli as it siioiiid be and veev iittle power is ob- ''ained in the engine. Where both the air and are reducedg the proper mixture is obained geting the full strengh of elle charge, yei; reducing the amount of charge and slowing` down the engine. v Referring now''o the drawings, repre sente the engine cylinder, having secured el. one end iie valve chamber which is in eommunioaion with elle e C,ine cylinder. Simpored ivihin *die opper end of Liie vaive eiieinber and spaced from the Wallis thereof .is an animiar member e, having on' annular gas passage 5, Conniinnieaing iviili the gas sun-ply pipe @l 'T Y n oortion of seid annular ea i opening 7, oonneoied iv e pipe 8.

gni/iler? member 4. Resting upon the Aupper end of ishe annular .chamber e is an enlarged n mier dat valve 10, which closes both the gannular air passage and also the gas pas'- lsages 9. The upper face of the valve 10 is `provided with an upwardly extending Stem il Winch exiends outwardly fthrough che 7 aive eliamber 0.' y'this arrangement it will be @at che suction or vacuum at ye end "if fe cylinder will lifL the valve o the ennniar member andallow the proper amount of air and gas to pass into yhe vaive chamber, and from-there into the i of die eyiinder. The upper end of the veive e is `provided with an annular" flange 127 through which the vaive stem ll ext-ends.

ing 'die member i? to the left or right the limit of upward movement of the valve is el'ianged The outer end of the Wedgesliaped member 17 is pivoally conneeted to a link 18g vaiiieli has its outer end pivotally eonneoied io a bell-crank lever. 19, operated by a governor-rod of the governor 2l.

From the foregoing description it will be seen that the speed governor 2l s connected 15o and driven by tile engine and when the engine speeds up the' rod 2O is` lowered by zlie. governor, iliroiving the upper end of kthe bello ank i9 to the right, drawing the link 18 and moving` Jdie wedgesliaped member if( so "roar the upward movement of the valve eannot be as great as when the Wedge is in ll'ie enreine position to Athe left. This, as will be readilyunderstood governs the :iinoimi of ai" and gas fed to the engine.

ne ive iiave shown 'this specific mangovi-Prning the upper movement of elle valve einen il; will be understood that this :nav be varied lliout departing from our claim `and desire to secu-re by Let.- ent is:

T J combination with a Tgasengine, of loer in communication with the l feines en annular gas sul(`- ply chamber vvithin the valve chamber and having communication with the upper end of the valve chamber, an air supply extending into the valve chamber and up through lvalve stem,4 Iwhereby the movement of the valve from the annular chamber is regu- `lated.

l 2. The combin-ation with a gas engine, of a valve chamber 1n communication vvlth the cylinder, an annular gas supply chamber within the valve chamber and having communications with the upper end of the valve chamber, an air. supply extending into the lvalvechamber and extending` throughthe gas chamber and in communication with the valve chamber through the center of the gas chamber, a valve of an area less than that of the valve chamber and closing both the `air chamber and gas supply, a valve stem extending through the valve chamber, and means for regulating the upward movement of the valve stem.

3. The combination with a gas engine, of a governor geared thereto', a valve chamber in communication with the engine cylinder, a as and air supply lfor thechamber, a valve normally closing said air and gas supply and opened by the' suction Within the engine cylinder, a valve stem carried by the valve and extending upwardl through the valve chamber, a cap vertical y adjustable upon the upper end of the valve chamber, and surrounding' the valve stem, and having oppositely arranged openings, a Wedge-shaped member extending through said openings andfengaging the upper end of the valve stem, and means operated by the governorfor moving the said Wedgeshaped member transverse the valve stem, substantially as shown and described.

4. The combination with a gas engine, of a valve chamber having its lower end in communication With the engine cylinder, an

annular gas supply chamber 'Within the valve chamber and in communication With the upper end thereof and spaced from the Wall thereof and forming an air'space therearound, an air supply extending through the valve chamber' and up through the annular gas chamber, and a valve resting upon the annular chamber and closing the gas and air communications and opened by the7 suction of the engine cylinder.

5. The combination with a gas engine, of a valve chamber having its lower end in communication with the engine cylinder, an annular gas supply chamber Within the valve chamber and in communication with the upper end thereof, and spaced from the wall thereof and forming an air space communicating with the upper and lower ends of the chamber, an air supply extending centrally through the gas chamber, a valve r'estin upon ythe annular chamber and closing t e gas and air communications and opened by the suction of the engine cylinder, and a valve stem carried by the valve and extending through the upper end of the chamber, and automatic means governed by the engine for regulating the upward move- `ment of thevalve stem.

6. The combination With a gas engine, of a valve chamber having its lower end 1n communication with the engine cylinder, an

`annular gas -supply chamber within the valve chamber and in communication with the upper end thereof and spaced from the lWall thereof and forming a space therearound, an air supply extending through the valve chamber and up through the annular gas chamber, a valve resting upon the annular gas chamber and closing the gas and air communications and opened by the suction of the engine cylinder, a va'lve stem carried by the valve and extending out through the upper end of the valve chanr ber, a cap vertically adjustable on the cham?- ber and into Which the valve stem extends, said cap having op )ositely arranged openings, a wedge exten in' through said openings and engaging tlievalve stem, and

lmeans operated by the engine governor for moving the Wedge transverse of the cap whereby the movement of the valve 1s regulated.

In testimony whereof We hereunto aiiix our signatures in the presence of two witnesses. l
