FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent N o. 69 6,903, dated April 1, 1902.

Application tiled .Tune 27, `1901.

To all whom, 715' .7n/(ty concern:

Beit known thatI, HERBERT H. I-IENNEGIN, a citizen of the United States of America, residing atAnderson, in the county of Madison, State of Indiana, haveinvented certain new and useful Improvements in Speed-Regulators for Gas-Engines, reference being had to the accompanying drawings, in which- Figure l is a View, partly in section and partly in side elevation, showing my speedregulating devices and the adjacent parts of Aa two-cylinder explosive-gas engine; Fig. 2,

a side elevation of the same, and Fig. 3 a plan View of the regulating-valve and connectingpipes.

`The object of this invention is to provide simple speed -governing devices especially adapted for that class of gasolene explosiveengines in which a pair of end-to-end cylinders are employed and the explosive mixture is supplied to them through a com mon pipe, the governing-valve being placed'at the juncture of said pipe with the pipe leading from the mixing cup or device, and the principle upon which this apparatus operates is to weaken or dilute the supply of explosive mixture to the cylinder-pipes by opening a valve and admittinginto the same more or less air, according to the excess above normal in the Speed of the engine, as more`fully hereinafter set forth.

Referring to the annexed drawings by letters, a designates the main shaft, and b one of the bearings therefor cast on the cylinderbody; c, a sparker cam receiving rotation through the reducing-geared from the main shaft;v e, a roller bearing on the cam and connected to the sparking-leverf, and g a sleeNe affixed to the main shaft and carrying the spring-connected governor-weights 7L, Whose forked arms i embrace and are pivotally connected to a sleeve j, adapted to slide on 'the main shaft a, this sliding sleeve being provided with an annular iiange 7n'.

The cylinder branchesl of the supply-pipes are connected to each other by a coupling in, which carries a transverse horizontal tubular valve-casingn, open at both its ends and connected near one of its ends to the branch o of the supply-pipe leading from the mixer or vaporizer. The branches Z of the supply-pipes serai No. 66.244. on) man.)

li ng m the val ve-casing is an n ularly enlarged,

forming an internal chamber p, in which works one of two reciprocating valves q, which is cylindrical in shape and tits and slides in the adjacent open end i' of the valve-casing, and is guided in this opening by a spiderguide s. A stem t connects the valve q to a similar-shaped valve u, working in and normally closing the other end of the valve-casing n, this valve being also provided with a spider-guide i. Surrounding this valve nis a coil-spring w, which is confined between an outward-turned annular (iangeon the outer end of the .valve and the end of the valvecasing. i

Pivotally connected to valve u is an actuating-rod y, and connected to the outer end of the rod y is a lever e, which is provided at its lower end with a roller e", which normally bears upon the outer face of flange 76.

Then the engine is running under normal speed, the weightsare normally held by their connecting-springs near to or against sleeve g, which keeps flan ge 7c pressed'against roller z' and holds valves u and q normally closed against the action of spring iu. When the speed rises beyond normal, the weights h swing radially outward and draw sleevej inward toward sleeve g, thereby permitting spring w to open the valves u and q and admit air to the valve-casing, so that on the suction-stroke of the engine more or less air Will be drawn into pipes Z, and thereby weaken or dilute the supply of explosive mixture to the engine, and thus nicely control its speed. It will be observed that the air thus let into the cylinder will either weaken the explosion or entirely prevent it, according as the air is admitted in smaller or larger quantities.

Having thus fully described my invention, what I claim, and desire to obtain by Letters Patent, is v l. Inaspeed-regulatingapparatusforagasengine, the combination of a pipe leading to the'engine-cylinder, a supply-pipe, an openendedl valve-casing connecting these two pipes, a valve Working in each open end of this valve-casing, one inward and the other outward and adapted to Aadmit air into both ends of the cylinder-Valve casing, a spring tending to open these Valves, and means for permitting the valves to open automatically when the speed of the engine increases beyond normal. A l

2. In a gas-engine, the combination of an open-ended valve-casing interposed in the.

` operated thereby, spring-retracted governorn weights on said shaft, -a flanged sleeve actuated by said governor-weights, supply-pipes for the explosion mixture and an air-admitting Valve in said supply-pipes, means tending to open said valve-to admit air, and means normally bearing on the flange carried by said sleeve and adapted to permit the valve to open when said anged sleeve is actuated.

4. In a speed-regulator for gas-engines the combination of a supply-pipe, an air-admitting Valve therein, a spring tending to open this Valve, and means adapted to release the valve and permit the spring to open the valveI when the speed increases beyond normal.-

5. In a speed-regulatin g apparatus for a gasengine, the combination of a pipe leading to the engine-cylinder, a supply-pipe, a valveeasingr connecting these two pipes and open at both ends, a valve working in each open end of this Valve-casing, one opening inward and the` vother outward and both adapted to admit air into the valve-casing, and means for simultaneously opening these Valves when the engine reaches abnormal speed.

In testimony whereof I hereunto afx my signature, inthe presence of two Witnesses, this 24th day of June, 1901.

HERBERT H. HENNEGIN.
