To a?? nfl/mi it may concern.'

Be it known that I, CHARLES A. KiNisEr, a citizen of the Fnited States, and a resident of Seneca, in the county of Venango and State of Pennsylvania, have made certain new and useful Improvements in Internal-Combustion-Engine Starters, of which the following is a specification. Y

My invention relates to improvements in devices for starting internal combustion engines, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide means by which the shaft of the engine4 may be rotated without the necessity cranking operation. c

A further object of my invention is to provide means for reversing the direction of rotation of the engine by the movement of a single lever. ,t

A further object of my invention is to provide means whereby liy wheel on the main shaft may be caused to impart its motion to the shaft itself by means of structures of a peculiar form.

Other objects and advantages Iwill appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accom-v panying drawings forming part of this application in which- Figure l is a side lview of the mechanism for operating the clutch: Fig. 2 is a horizontal section through the liy wheel and clutch mechanism. i.

In the following description of the device, I shall set forth only those parts which are new, and are necessary to an explanation of the working of the device. The device is applicable to internal engines of any type.

In carrying out my invention, I provide the main shaft S with a liy wheel F. The fly wheel F is not secured to the shaft but revolves loosely thereon. On one side of the fly wheel is an annular groove or channel C having an outer frictional contact surface c and an inner frictional contact surface c. Pivotally secured at m on the frame member M is a yoke Y, while rotatably mounted in the yoke is a small stub shaft S bearing a gear g arranged to mesh with a gear G, which is keyed to the shaft-S. The end of the stub shaft s is provided With a friction wheel W, which is adapted to engage either of the usualv the rotation of aV on the fly to a lug Z on the of the contact surfaces c or c wheel. A rod r 1s secured shaft S'- This rod 7' is connected to a rod rx by means of spring connections ry.V The rod rx in turn is L. The lever handle L has three positions; one a neutral position shown in the figure; another position a which will impart a direct or. forward movement to the engine, and a position b' which is the reverse position.

Secured to the lever L is a second ylever L which is connected by a. link ZX. with another link ZY. The latter is secured to a bell-crank lever K pivoted at and connected by a link Zz to a rod rw which operates the swinging link fr" pivotally connected at its bottom to the rod r* which governs the magneto or fuelV feed, not shown.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The fly wheel F is started in any convenient. manner and after a sufficientmomentum is 0btained the lever L may be manipulated to turn the engine in either direction. Thus if it is pushed forward to the position a, the friction wheel IV will engage the inner 4friction surface c of the fly wheel, thereby turning the wheel W of the shaft S and the gear g in the opposite direction from that in whichthe fly wheel is running. The gear {j engages thege'ar G on the shaft,.and therefore turns the shaft in the same direction in which the fly wheel is running. lWhen the lever L reversed to the position Z), then the friction member w is pulled against the contact surface c of the fly wheel F and therefore the wheel YV, the shaft S, and the gear G, revolve in the same direction with the-fly wheel, while thexengagement of the gear G with the gear g drives the shaft in the reverse direction from that in which the ily wheel is rotating. When the lever L is at the position shown in Fig. l, then the friction member 'w is free from the contact surface c', and the rotation of thefly wheel therefore will not affect any movement of the engine. At--the same time that the lever` L is being shifted, thelever LV is shifted so as to cut off either the magneto circuit, or the fuel supply by means of the rod rt. Since the shifting of the lever L is accomplished by merely grasping the latter with the fingers, when manipulating the lever L, it is obvious that the fuel supply may be cut connected to a lever handle Wheel W 'member arranged to contact groove,

off when .the lever L is being shifted in either direction. Y

While I'have shown the as a friction clutch, it is may be ay gear, gaging surfaces c and c may be provided with rack teeth, withoutdeparting from the spirit or scope of the invention. claim y v 1.
