ln the accompany-ing drawing We have. illustrateda'pre er Be it known'that we, JAMES B. KENDALL and HOWARD M. .EWING, citizens of the United States, residing respectively, at Chicago, in the county o Cook andState of Illinois, and St. Louis,"State of Missouri,

have invented certain, new vand useful lmfollowing is a. specification.

Our invention. relates to improvements in mean-s for starting internal-combustion gasengines-the pistons of which must ordinarily be moved tof compress Vthe Acharge of gas-t0 provements in Engine-Starters, of which the effect the initial explosions and thus start the operation ofthe engine.'

. Referringto the details of the drawing,

3 represents a. metalV cupeshaped shell which .forms a casing nfor parts of the devicetobe presently described. It is provided 1. with a central opening 3, and at spaced intervals .on its periphery it is formed :with internal itted to the casing 3 is. a; cast metal platel fl, which is formed vwith a centxgal hub 4 Vthose ofysimple and 1 thrc'iugh which extends an opening inv line with the opening Sn.. Said plate is also formed with a stud4b which projectsoutl arm 4t which lies parallel with the said plate and forms a support for a clutch., lever hereinafter described. `The sttid` plate 4 is secured tothe shell screws 4g, whichengage threaded holes in the lugs 3b. Thev 'shell 3', with its cover plate 4, is carried .by a sleeve 5 rotatably mounted upon the engine shaft 6. `The sleeve projects beyond the Said eover plate 4 and is provided at the extremity with ratchet teeth 5a, formed in ,its end face. Mounted upon the sleeve 5 im- -mediately within the'cover plate 4 is a. gear wheel 7, having' an extended huba, secured kto the' said sleeve by a key 7b. Arranged within the shell 3, is a. coiled ribbon spring 17"* having'its inner end secured to the hub 7 of the gear 7, while its outer end is' formed into an'eye 7d, engaged by a pin 7, secured in bearings If formed on the shell. Mounted upon the said sleeve 5 outside the cover plate.- LIsis. a pinion 8 which is adapted to mesh with a. segmental gear wheel 9 jouirnaled on a shouldered stud 1G having a threadedengagement with theplate 4. The

y said stud 4* is bored longitudinally to vIieceive a shaft ll, carrying lupon its. outer end 'a geary 1l and upon its inner endwhich projo-ets through the cover plate 4, is keyed .a pinion 1lb meshing .with the. said. gear 7.

Mounted upon the engine shaft 6. adjacentthesleeve 5 is aclutch sleeve 12,3. spline 12 permitting the sleeve to slide longitudinally on the shaft, at the same time insuringv its rotary movement therewith.. The said sleeve Yao has' a peripheral groove 12b in which is loosely mounted a saddle block 12. A lever 13 pivoted at 18a to the arm 4t has one end biurcated. to .form yoke or fork 13, the arms. of' the yoke. y eing pivotally attached tothe saddle ecklZ by pins 13,

Aina manner 'commonfh clutch const-nichon.

The lower end of the lever 13 is provided with- 'a hole 13'd for .the attachment of an operating rod (not shown) and adjacent this end is an. enlargementor counterbored to receive a spring 14 secured 1n place by a threaded plug 14e. -Opposite'the said sleeve 12 is a A#shaft 6 will have been rotated a suiiioient J the clutch sleeve is thus thrown over toward end of the yield to give4 the proper movement to the engage with the teeth 5a 'and 15a when ,op-z

' the engine, the. lever 13 is moved so as to vthe hole 9a, releasing the gear 9, and perexertedon the shaft 6 through the sleeves ,9 will be rotated in the direction of the arvthe gear 9 is so related to the latter in pitch plug is a suitable 'hole through which the body of a pin 14:b passes, the head 14:c of the pin being retained in the bore of the boss and engaged by said Spring 14. This pin 14h is extended through a suitable hole in the hook shaped lug 4d and is adapted to engage a suitable hole 9 in the Web of the gear 9. Projecting outwardly from the face of the said gear 9 is av lug 9b, which is adapted to engage ,the undeizcurved surface 13 of a lug 13g extending laterally from the lever 13, when in its initial or normal position, shown in Figs. 1 and 2.. The under side of the said lever 13, adjacent the base of the fork 13b is beveled to form a cam face 13h, with which the said lug 9b will engage when the said gear 9 is turned on its center. Mounted upon the engine shaft alongside the clutch pinion .15 having ,teeth 15? similar to the teeth in the sleeve 5, formed in the side adjacent the said sleeve 12. The latter vis provided upon -its opposite end faces Awith teeth 12d adapted. to alternately erated by means of the lever 13. An intermediate gear wheel 16 journaled on a stud 16a secured in the arm, 4, connects' the pinion 15 with the gear 11a.

The operation o f themechanism is as follows't-The spring being wound it is held in a state of tension by the pin 14h.. To start carry the clutch sleeve 12 toward the sleeve 5 and bring the teeth 12d into mesh with the teeth 5a on said sleeve 5. This movement of thelev'er 13 will withdraw the pin 14h from mittin'g Vthe full force ofthe spring to lbe and 12, and as the said shaft rotates the gear row a, Fig. 2. The pinion 8 which drives that when the said gearV has beenturned a little less than one-half a revolution the number of times to start the engine.4 Just at this point in the movement the lug- 9bV on the gear 9 will strike the cam surface 13h and throw the clutch sleeve 12 in the opposite direction,- so as to engage the pinion 15, and as the clutch 12 is now in motion with the rotatingl shaft 6 .the train of gears 16. 11a, 11"l and 'T will turn the sleeve 5 in a direc- .tion to wind up the main spring 7c. When the pinion 1'5 the opposite end of the lever 13 will move toward the plate4, bringing the pin 14 'into contact with the side of the gear 9, but this will not interfere withthe lever movement since the spring 14 will said pin, and when the gear 9 returns to its initial position, the piirwill renter the hole 9*, locking the gear -9 and sleeve 5 as at first,

As the said gear reaches its initial position the lug 9bwill engage the cam surface 13 on the lug 13g, and throw' the clutch sleeve 12 to its initial position, shown in Fig. 1,

where it is' out of engagement with either ratchet, and the entire device will remain in a stateof rest in this normal position,

mounted on said shaft, a spring operatively connected with said sleeve, a pinion loosely mounted on the shaft, a train of gearing connecting said pinion with' said sleeve, a clutch memberA splined on said' shaft and adapted until the lever 13v is again operated to start l to alternately engage saidsleeve and pinion,

a lever adapted to operate said clutch member, apinion mounted on said sleeve, a gear engaging saidpinion, means onsaid` gear for operating said lever, and means for locking said gearv in its initial position.
