APPARATUS FOR GOVERMHG GASSTEAM, OTHER lilfilllil FQWER EiiGii-ihi SPECIFICATION formingpart of Letters Eel-tent Ho. 6%, dated September 5, 1%31 Application filed February 13, 1893, &risl1i'o. 482,187. (No model.) Eetented in England January 28, 1835, lie 1,213, and April 23, 1891; H0 7,813

No. 7,313, dated April 28, 1891,) of which the following is a specification.

My invention consists in constructing governors for regulating the speed of gas engines, r5 steam engines and compressed air engines in the manner hereinafter explained whereby the regulation of the speed of the engineis efiected hy mechanism much simpler than.

that ordinarily employed, the present invenzo tiou being an improvement on that described in Letters Patent No, 339,461, dated April 6, 1886.

I will describe my invention in connection with a horizontal gas engine from which its 2 5 other applications will also be understood.

Instead of being worked in the way heretofore described in my said patent'lmay work the arrangement from a second motion shaft by means of a cam, the lever or pusher it 0 which acts upon the valve opening arrangeinent being provided with the iHGlll16' '/L as heretofore the said lever and incline being carried by a lever-arm centered to any suitable part of the engine the said lever being 5 provided with springs which keep the. said lever in proper position and enable the gov erning'arrangement to be usedin any position. One of the sai springs can by means of escrow be employed as a regulating spring 0 so that Toy-operating the screw the speed of the engine can be regulated without stopping it.

The invention can be more fully understood by reference to the accompanying draw- 5 ings forming part of 'this specification, in

which- Figure 1, is an end view of a gas engine to which my improvement is applied. Fig. 2, is an elevation, taken from the right of Fig.

' 1, of the regulating mechanism. Fig. 3 is a 50' view similar to Fig. i, the casing around the inlet and exhaust valves being in section, and Fig. i is a side elevation of Fig. 3, certain parts oeing omitted.

The clock in carrying the incline 'n. and le- War or pusher 7a are here shown as being fixed at the end of the lever h the opposite end of which is centered on a pin it and is provided with projections h and h to which are attached the springs d and d the spring d'serv- 6o ing to keep the roller '5 atthe lower end against the earn J driven by any suitableconneotion with the working parts of the engine while the spring (2 (the lower end of which is connected to the projection h on the block m) is nsed for regulating the speed of the engine being adjusted by the mute? and boltdt When the engine isworking at its normal speed the end of the lever is the latter being thrown into operation by the incline n on block m engging the roller g strikes the top of the lever e, on the shaft X rotating the latter and causing arm a carried thereby to open the gas inlet valve A by engagement with valvestem a (see Fig. 8) but if the speed of theengine increases beyond its proper rate the outer end of the lever 70 will be thrown over the top of. the lever@ and so no gas will be given to the engine.

At the end of the shaft opposite to the gas 30 valve'l fir; a small lever cc, which works against the stopg against which it'is held bya spring ,2 thus insuring the levers being held" in the same position after being operated by the governor, By this arrangement the governing 8 'earcan be used in any position. The leverand the roller i both work on the same pin 11 held in its place at the bottom or lower end of the lever h by the nuts 72 Theexharist or discharge valve 13 is raised on from its seat at suitable and proper intervals by a pivoted oscillating lever 1) eng ing valvestem I) at one end, motion being imparted thereto at its other end by cam J'.

Althoughl have described and represented 5 "my invention in its application to a horizontal gas engine yet my said invention is applicahie to-vertical gas engines as well as to horizontal and vertical steam a l a 504,613

engines and compressed air engines. A 1 1 Having now particularly described and ascertained the nature of my said inventionand' in whatmanner the same is to be performed, I declare that what I claim is Y '1. In a' gas, steam or other fluid motive power engine, the combination with a lever for operating the inlet valve, of a supporting arm pivoted at one. end, an oscillatory lever fulcrnmed in theopposite end of "said arm, the forward end of whichis adapted to be ens gaged at intervals with the valve operating lever, an incline on the oscillating lever engaging a rigid projection for moving said lever to the proper position for contact with the valve operating lever, aspring for limiting the lift of the oscillating leverby the incline, during the normal speed of the engine, but which allows it to escape the valve lever when said speed is increased, a spring for holding the oscillatory lever, at the limit of its rearward movement,and means'for imparting an oscillating movementto the latter, substantially asdeseribed. 4

'2..In agas, steam or other fluid motive power engine, the combination with a lever for operating the inlet valve, of a supporting arm pivoted at one end, anv oscillatory lever fnlcrumed in the opposite end of said arm, the forward end of which is adapted to be engaged at intervals with the valve operating 'lever,.a'n incline oil-the oscillating lever engaging a, rigid projection for moving said lever to the proper position for contact with-the valve operating lever, a spring for limiting the lift of the oscillating lever by the incline,

during the normal speed of the engine,'but' which allows it to escape the valve lever when said speedis increased, means for adj usting the tension of said spring, a spring for holdmg the oscillatory lever at the limit of its oted at one end,-oppositely extending projections or cars on the pivoted end of the arm, an oscillatory lever fulcrumed in the free end of said arm, the forward end of which is adapted to be engaged at intervalswiththe valve operating lever, an incline on the oscillatory lever engaging a rigidprojection for moving the leverto the proper position-for contact with the valve operating lever, a

spring connecting one of the ears on the supporting arm with the oscillatory lever for limiting the lift of the latter by the'incline during the normal speed of the engine, but which allows it to escape the valve lever when said speed is-increased, a spring connected with the other car of the supporting arm, forhold ing the oscillatory lever at the limit of its rearward movement, and means for imparting an oscillating movement to the latter, substantially as described. v
