A pair of arms 28 and i9, provided with inclined forward faces 30 are bolted to the base of the engine 2, the forward inclined faces being adaptedI .to be engaged by the spoke 13 ofthe segment as will be herein'- after; described. Connected 'at' vone end' ofA the segment 14 by-means of the screw 31 is a chain 32, which is located. around the groove in the segment and which passes over the compound pulley The compound pulley 1s composed ofl a large sheave 34 and a small sheave 35, which are preferably made integral, thel chainA 32 passing first around the large sheave and then up and around the smaller sheave. The c hain is then continued back-'along' the chassis and around the segment 36, said segment being 'mounted for rotation upon thensual brake rod 37, the hand lever 38 being xedly connected to said segment and voff-set therefrom at 39. It will be understood that .the segment is merely mounted .upon the usual brake rod as a matter of convenience, but it may be pivoted in any suitable position upon the machine. y

A bracket 40 is mounted in a suitable position upon the dash board of the machine, said bracket being provided with apair of spaced arms 41, which receive the operating lever, friction blocks 42 ofrubber or simi-lar material being provided upon the side faces of the lever. Thus when the lever is in the inoperative position as shown in Fig. 5, the

arms 41 frictionally engaging. the blocks 42.

will hold the lever against displacement.

Mounted upon the forward end of the engine is a horizontally disposed bracket 43 upon which bracket is pivotally mounted the plate 44, the spring 45 passing around the pivot 46 and having its extremities bearing against the edges of the bracket and the plate 44, thus normally holding the plate in contact with the stop screw 47 as best illus-- trated in Figs. 3 and 6. A roller 48 is mounted at thel forward extremity of the plate 44 and arranged to engage the segment 14 as shown in Fig. 3. `This mechanism is for the purpose of 'preventing the teeth upon the clutch member 17 from riding over the teeth upon the clutch member 7 upon the return of the segment to the normal position.

The operation of the device is as follows: The parts being normally held in the position shown in the several figures of the drawings, the arm 13 of the segment 14 is held in engagement with the inclined face of the arm 2f), thus holding the clutch member 1.7 out of engagement with the clutch member 7. W bcn it is desired to start the engineA the hand grip 4S) of the operating lever is grasped and pulled forwardly, the segmerit 14- being revolved,'bringing the spoke 13 out of engagement with the iu-I clined face of the arm 29 and allowing the clutch member 17 to engage. the clutch meini ber 8, thus rotating theengine shaft 3. The segment 14, contacting with the roller 48, as itmoves in this direction will cause the plate 44 to move upon the pivotal point 46 allowing the spring 18 to slide the sleeve 12 rearwardly, throwing the clutch member 17 into engagement with the clutclrmember 7. As the segment 14 completes its movement the spoke 13 will engage the inclined face -of the arm 28, thus throwing the clutch 'members again out of engagement as the eugine is started. The. spring 45 will then throw the plate 44 into the normal position, the roller 48 engaging the segment 14 and holding the

clutch members

17 and 7 apart as shown in Fig. 3 and as the operating lever is released the coil sp'rin'fr 26 will pull the segment .and its accompanying parts into the normal-position.' .As the clutch 'members are held apart yby means'of the plate 44 and roller 48 the teeth of the clutch member 17 will not click or ride over the teeth of the clutch member 17 upon the return movement. It will thus be seen that at all times while the device is not in operascrew which is provided for the purpose of taking up slack in the chain 32, said adjusting screw being located through the lug 5l in the segment 36 and bearing against the shoulder 39 of the' operating lever.'

Although the drawings and above specification disclose the best mode in which I have contemplated embodying my invention I desire to be not limited to the details of such disclosure, for, in the further practical application of my invention7 many changer in form and construction may be made, as circumstances require or experience soggests, without departing from the spirit of: the invention, within the scope of the appended claims. I claim: 1. In an explosive engine starter, comprising in combination with an explosive engine shaft, areceiving clutch member fixedl y mounted upon the shaft of said engine, a second sha-ft arranged in alinemcnt with the engine shaft, a movable clutch member slidably mounted upon said second named shaft, i
