GOVERNOR FOR EXPLOS'IVE-ENGINES.

Specicaton of Letters Patent. v Patented NOV. 17 1914.

Application filed November 1, 1913. Serial No, 798,618.

1-'0 au 'whom it may concern.'

Bev it known that I, CLAUDE SiNTz, a citizen of the United States of America, -re-' siding at `Detroit, in the countyv of layne and State of Michigan, have invented certain new and useful Improvements in Govl ernors for Explosion-Engines, of which the following-is a' specification, reference being hadtherein to the accompanying drawings.v My inventionlrelates -togovernors for eI;-v

plosion engines and has among the objects vthereof to provide a simple and eliicient oonstruction for adjusting the governor valve, and to provide-a device in which the proper seating of the valve will at all times be insured.

Other objects of the invention will more fullyghereinafter appear.

The invention resides in the peculiar construction, arrangement and combination of parts as hereinafter vset forth and as parf ticularly pointed out in the claims. In the draWings,-I1`igure l is a sectional side elevation of the device embodying the invention; Fig. 2 is a section on the line :ie-zr of Fig. l.

A designates a casing vforming a portion of the induction conduit leading to the en;

gine, B the inlet therefor, and C the outlet.

D is the valve seat composed'of a cylindricalinember eltending transversely of thel casing A' and having the opposite ends there- 0f seated in bearings E F in the, casing. This valve seat is 4provided with a plurality of slots H in the upper side thereof, and with corresponding slots I -in the lower side,

providing a l'ilurality of spaced segmental portions (i. The valve J is arranged in the cylindrical member Dfor longitudinal slid.`

ing movement, and` is composed of a member having a plurality of spaced circular sections l''correspoi'iding in number to the slots I-l and each of a width slightly greater than these slots. lvl/hen the valve is open the parts are as vshown in Fig. l, but when the valve is adjusted longitudinally the slots H Will be'lmore or less restrctei'l, or con'ipletely closed, according to the adjustment 'of the valve-as will be readily understood.

The .shifting of the Valve is controlled by a centrifugal governor composed of arms L M arranged at substantially diametrica'lly oppositepoints upon'a sleeveN.

are springs connecting the Weightedends.

P and tending to hold the Weightedl ends at their inward position of adjustment, 'inthe usual manner. The sleeve N is journaled up'on an extension Q ofthecasing A and is provided Wit-ha sprocket R which is driven 1n any suitable manner from vthe crank sha-ft.

S '1s a longitudinally shiftable shaft slidably arranged Within a bore T in the extension Q and carrying at its outer end a thrust 'bearing U engaged by the ends V of the centrifugal arms. 'The inner end W of the shaft -S abuts against the inner end of the' valve J.

The opposite end of the casing from the centrifugal governor is provided with a head A which closes the outer end .B of the valve D. This head. is provided with a bean.,r

ing C Within which is arranged. for longitudina-l sliding' movement a shaft D5," the inner end of which abuts against the outer end of the valve J. v

E is a lever pivoted at F to an arm G suitably mounted. upon the vcasing A, 'and this lever has vthe end F2 thereof engagin the outer headed end ofi-G2 of the shaftD Connected-to the opposite end` H of the leve!i E is a Sp1-in -f I that tends to move the lower end F2 oA the lever E inwardly and thereby exerts a yield-ing pressure upon the shaft D', tending to move the latter in a direction to maintain the 'valve open.

lVith thecon'struction so far described, when the speed of the engine becomes too great, the gmfernor arms I will be thrown outward by centrifugal action, since vasbefore stated, the sleeve N is driven from .the

The outward increment of the crank shaft. governor arms will more the shaft Slongitudinally inward, which will shift the valve to vnriably` restrict the ports Il, thereby restricting the flow 'of gases through the casing A. filon the "speed of theengine decreases so that the sin-ing 0 of thel governor arnlsinoves the latter inward, the.

spring I will act upon the'shaft H- through tlie medium of the lever E to move the valve in the opposite direction. The speed at which th'e governor arms are thrown out- "1' meansfof an adjusting bolt JA", which has a vthreaded engagement. with a. ixedbearing '1K' eveneens @emmene 'tette spring 1 Thus by'adjusting the bolt J "7' the tensionof the spring I" may-be varied, and

i fi gino@ `the centrifugal; arms must'move the valve against the-'tensionjof the s ring I',

"this willfincrease the force require to 1iio i r a 4 '4 the governor-arms outwardly. By this'mam,

'- ner of adjustment the' governor may bevery accurately regulated.V

In or, er to reducethe Wear 2 0 seatso asto be freeV to oat therein. The

I suctioiircreated in the casing A during the working ofthe engine will draw the valve upwa l y against the segments GrA in the ,uppeiiiiortbn of the 'valve seat, and therevalve and will also reduce the wear between the valve and its seat to a having the yielding, meansv which op the action of the 'overnor arranged atl-.thefopposite end 'of t e valve from the f -centrifugal governor mechanism, this yielding means willv automatically take up any wear in the governor parts and thereby insure greater aecuracvyujn the operation of the valve and avoiding what is generally known las back lashing of the parte.A
