- bein csiec-iall directed to the "overnim b r: a

and sparking mechanism therefor, and has for its objects to produce a comparatively simple, inexpensive device of this character, wherein one of the sparking members will be moved out of the path of the other during each alternate instroke of the piston, or that is, during the exhausting intervals, and one wherein the movable sparker will, m the event of the engine speed increasing beyond apredetermined limit, be automatically moved out of the path of the other spark-er and maintained in such position until the speed has decreased to normal.

. A further object of the invention is to provide a device of this character with a sim-- plified form of mechanism for operating the movable sparker, one in which said sparker will be automaticell moved to inactive position siniultaneousltv with the opening of the exhaust port, and one wherein the parts will upon an abnormal increase in the speed of the engine be locked for maintaining, the exhaust open and the movable sparker in inactive position.

'With these'and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the'accompan ing drawings: Figure l is a side elevation e an en ine equipped with a mechanismembodying t e invention. Fig. 2 is a. similar view looking from the other side of the engine; Fig. 3 is a rear elevation of theisame. Rig. 4 is a to plan view of the samef Fig. '5 is a detai, sectional, view taken on the .line"5--5 of Fig. 2 and showing the pants on iinenlargcd scale. Fig. 6 is a front view of the governor weights and adjacent parts. Fig. 7 is a detail, sectional view taken on the line 77 of Fig. 6.

, Referring to the drawings, 1 designates an engine base sustaining a. cylinder 2 in which is and ed for reciproeationa piston 3, the rod 4 which is connected at its rear end with eccentrics 5 carried by a drive shaft 6 'ournuled in suitable'split hearings in the base 1 and euuinped with lly wheels 7, these parts except as may be hereinafter exit being of the. usual or any preferred tinnsc i'rxe-il upon the shaft 6 for rotation there- 'lfi'! H a gear 8 1n mesh with a second gear 9 l0 journalcd in the base 1 and contnininq a. longitudinally movable operating member or rmi i1 pivotally engaged at one end with a. locking member or dog 12 in turn )lVOtltl to a suitablebearing 13 onthe base 1, t icre being loosely mounted upon the rod 11 a cross head or piece 14 having int-urned portions or lingers 5 projecting through suitable openings in the governing wheel 9 within the path of am! for engagement by the adjacent, inwaniiy. extending portions or arms 16 of a pair of weighted governor members or lovers 1? pivmed in suitable bearing openings in the whee-i 5* and held in normal position under the im'iuence of s )rings 18, there being tapped onto the at jflCtlll. end of 'rod 11 a baa-r1 :i nut 19 designed for fixing the cross piece 14 against movement longitudinally of the rm. llj It will be noted in this connection 135211 when the speed of rotation of shaft 6 increases beyond a predetermined limit the weighted ends of governor levels 17 will swirq: outward by centrifugal action, as usual, thus causing the inner portion 16 of said le- YE-ITS to act upon the lingers 15 and through the r" iium of cross piece 14 move the rod 11 l the f.- end of the locking member 12, as in. (lit-axed b v the arrow in Fig. 4, and fora purpose EmiiCl'l will hereinafter appean In rvlinder 2 is )I0\' ltlt with an inlet l port 2 and with an exhaust port 21 adapted suitpfi able 5; at the rear end of the cylinder and having a valve carried b v a longitudinally movadapt swung urn ard, as heretofore cxplnlncd. j

in turn fixed upon a tubular governor shaft nudinallv in a direction for swingingto e pened or closed under the-action of a n 22 slidnblv disposcd in a bearing out t; R K'- path of the locking member 12 and i for engagement b v the latter when L'Ui'15:l' a (il()l\ and arrangement and adapted in practice t-U-Iifil'ffllill their ordinary fune-.

head 2 disposed in the path of crank arm iio ing a head 52 Mounted in a bearing 35 provided in the wall of the cylinder 2 at a point adjacent its movement into and out of the path of a sec-' ondary sparking member or contact 39 fixed upon the piston head 3.-

Fixed upon the outer end of shaft 37 is a .crank arm 40 to the outer end of which there is pivoted by means of a tubular coupling member 41, a hearing member or sleeve 42 having slidably arranged therein the upward end of a rigid connecting element or red 43, the rear end of which is connected by means of an eccentric strap 44 with an eccentric 45 fixed upon the shaft 10, there being arranged upon the rod 43, which is provided at its up ward end with a head ore largement 46 a normally expanded spring $7 arranged to hear at one end against the sleeve 42 and at its other cndagainst a bearing shoulder 43 on the rod, while fixed upon theshaft 10 at the end thereof remote from thhgcccentric 45 is a cam member or head 49 arranged in naled to the lever 30 and adapted fo locking the latter to move the rod 29' forwhrdly as indicated by the arrow in Fig. l to operate the rock shaft26 for actuating the exhaust valve to open the port 21.

Journaled in the-tubular coupling member 41 is a second coupling member or pm 51 hav vrovidcd with a bearing opening 53 in which is slidably arranged one end of a connecting rod or link 54 provided at a point snitabl remote from said end with a bearing shoulder 55 and having its other or forward end pivotally of .a coupling link 56 with a fixed bearing phrtion or arm 57 projecting from the outer end of crank arm 25, as seen more clearly in Fig.

In practice, as the'shaft 6 rotates the shaft 10 will be driven therefrom through the me dium of gears 8 and 9 and the cam head49 will, during each rotation of the shaft 10, set upon the roller 50 for rocking lever 30 and moving the governor rod 29 forwardiy, wherebv the rock shaft 26 will be operated to move t 1e arm 25 into contact with and for o enin the exhaust valve as herein after exp aine it ben J understood that the shape of the cam 49 is such that the exhaust valve will be open durin each alternate instrohe of the piston 3-, or that is, during ap roprisze intervals for exhausting the explo ed gases from the cylinde 2. During the rotation of shaft 10 the rod 3 will be actuated through contact with'an antifriction roller 50 jourwar'd through the medium of crank arm 25 a 1 operation, as just explained. It will be seen connected by means 'ooepn the medium of the eccentric 45 for iockingthe shaft 37 to move the sparking member or contact 38 into and out of the path of the 00* operating sparking member 39, it being inderstood that during the normal operation of the parts the movement of the contact 38 to inactive position, or that is, out of the path of the sparker 39, will'be simultaneous with the exhausting stroke of the piston 3 and the movement of the exhaust valve to open position, and further that under normal conditions the rod 54 will havesuflicient longi-. tudinal play in the bearing opening 53 to permit the proper movement of crank arm 40 without coming incontact with the stop shoulder 55. hen the speed of the engine increases beyond the normal the governor members 17. will,'in swingin outward, move the rod 11 longitudinally and throw. the lock-.. ing member 12 into the path of keeper 32, as heretofore explained, thus. locking the governor rod 29 against movement with the exhaustvalve open, under which conditions the link 54 will be moved longitudinally rearsuflicient distance to bring the abutment 55. into contact with the head 52 andact upon the arm 40 for fixing the shaft 37 against movement with the sparking member .38 held out of the path of sparking'member 39, in which position the parts will be maintained until speed of the engine decreases "Suthcicntly for the governor members]? to return to normal condition under the action springs 18, whereupon the locking member 12 wi 1 be actuated or releasing the partsnnd permitting a continuance of their normal at when the locking rod-54 is moved to sition for holding the arm 40 and shaft- 37 against movement the s rin 47 ermit the rod 43 to play i ly hack an forth through the bearing 42.
