Specification of Letters Patent.

Patented Mar. 2i., 1913i.

Application. ied March. 7, 1910. Seri-MENO. 547,769.

ToV all whom it may concern:

Be i-t known that Jol-1N W. Bl-nolNeEn, a citizen of the United States, residing at lV'ashi-ngton,` in the county of Baviess and Sta-te o-f4 Indiana, have invented a; new and 'useful Engine-Starter, of which the following a specification.

This invention relates to starters for hydrocarbon engines such used upon automobil'es and one of its objects is to provide improved means whereby the starting mechanism can be readily actuated by the chauff feur without leaving the vehicle, said `mechanismV being of sim-plel construction vand con venient to attach to different makes of machines. L

Another object is to provide. improved meansI whereby the actuating mechanism will be automatically disconnected from the starting-shaft yshould the engine start back- Ward 'as the result of premature sparking.

With these and other objects in view the invention consists incertain4 novel details of constructionand combinations o-parts hereinafter more fully described 4and pointed out in the claims.

In the accompanying drawings the pre'- ferred form of the invention has been shown.

Insaid drawings. Figure 1 is a bottom plan' view of thevniechanism portions thereof being shown-in sect-ion and the bottom of the gear case being removed. Fig. 2 is a side' elevation of the 'starting mechanism. Fig. 3 is a section through the pawl and ratchet mechanism. f

Referring to the figures by characters of reference 1 designates .a gearcase designed 'to be secured in any Vsuitable manner to a fixed portion of the frame or chassis 2. A starting shaft 3 is journaled'wthin the case 1 and'may, if desired, be provided with a 'crank 4 atitsouter endwhilethe inner end of said shaft has a clutch case 5 designed to engage acorrespondingface formed upon the adjoining end ofthe motor shaft,notshown. y.This shaft 3 is mounted to slide as wellies rotate within its bearings and has a collar 7 's ecuredu'pon it and provided with L., an annular grooveB. 4A gear 9 is feathered l V:so

on the shaft 3, and is located within the case 1', there being a, coiled spring on the shaft 3' and bearing at its ends against the collar 7 and the gear 9 respectively so as to hold the shaft 3 normallypressed forward with its clutch face G out of engagement with the u'lot'or shaft.

A shaft 11 is journaled within the case 1 and extends laterally therefrom and: is also journaled in one side of the franle or chassis 2. This shaft has a gear 12 secured thereto and located within the case l, the said gear meshing at all times with the gear 9. A ratchet wheel 13 is secured to the outer end of the shaft 11 and located Within the fork of an arm 14 which is mounted to swing loosely on the shaft 11. The free .end of this arm is pivotally connected to one end of a rod 15 which is also pivotally connected toa starting lever 16. This lever is located at one side of the machine and preferably cljose to the chautfeurs seat. A pawl 17 is pivotally mounted within the forked arm -14 and: a spring '18 bears on this pawl and holds it normally in engagement with the ratchet wheel. A finger 19 extends vinwardly from the pawl and is adapted, when the arm 14 is swung a predetermined` distance i-n one direction, 4to move against a deflecting arm 2O extending downwardly from a plate 2-1 which is secured. to the frame 2. l V

A shaft 22 is j ournaled within the top and bottom of the case 1 and extends through -said case, there being an arm23 'on the shaft and Within the case and which projects into the groove 8 in the collar 7. Another arm 24 extends from the lower projectingI end of the shaft 22 and has a flexible actuating device, such asa cord, chain or the like which has been indicated at 25, the said device being secured to the free end of the'arm 24 'and being extended partly around a sheave- 26 mounted upon a bracket 27 secured to -the frame 2. The connection 25 extends back to the lower end ofa foot lever 28 which is journaled within the frame 2 and preferably close to the seat of the chauffeur.

In using the mechanism which has been described the foot lever 2 8`is first pressed This causes the' connection 25 to' pull onarm 24 and the shaft' 22 s thus ro.-

forward.

-tated so as to swingthc arm 23 and push the collar 7 and the-shaft 3 longitudinally.

The -clutch face 6 will thus be brought into engagement withthe adjoining end of the motor shaft, not Shown. It will be understood of course that the gea-r 9 remains in ,y

mesh with the gear 12 inasmuch as shaft thence to the shaft 3. As long as this shaft 'suddenly pull the lever' 1G away from'the -eonstruction and will be found `:nlinanta- `ferent makes of machines and because of the is slidably mounted Within'said gear 9.l After the parts have thus been shifted the' lever 6 is oscillated. Each forward movement of the lever Will swing the arm 14. so as to cause the pawl 17 to ride over the teeth on the ratchet ivheeL Each movement otE the lever 16 in the opposite direction Will l cause the pawl to engage the ratchet Wheel and Arotate it. Shaft 11 Willtherei'ordbe correspondingly rotated and motion will be transmitted through gear l2 to gear 5) and is in engagement ,with thc motor shaft, the said motor shaftwill be also rotated. Should the engine start in the Wrong direction the movement of shaft 11 would be reversed, and the pawl, engaged by the ratchet Wheel 13, would be thrown in the direction of the arm 20, thus causing arm 14 and rod 15 to operator. Upon the completion ofV a short movement of the paivl 1T in this direction, the finger 19 on the pawl will ride against the arm 2() and said arm will deflect the linger inwardly a suflicient distance to disengage the paWl from the ratchet Wheel. The clutch face 6 will oi course become disengaged from the motor shaft assoon as the foot lever 28 is released, the spring 10 serv ing to .fproinptly shift the shatt longitudinally` soas to disengage the tivo shafts.

It will be seen that starting mechanism such as has been described is very-simple in' geous because' it can be readily applied to diffurther vfact that it vbecomes unnecessary for the chauffeur 4to leave the vehicle when he desires to sta-rt it.

Various changes can of course be made in the Vconstruction and` arrangement of the cluding a starting shaft,` a collar thereon, a-

feathered on the shaft, manually opgear erated means engaging the collar for shifting the shaft longitudinally Within the gear, a spring uponthe shaft and bearing against the gear and collar to hold the shaft nor'- inally in a predetermined position, asecond shaft, a gear thereon constantly meshing with the iirst mentioned gear, means mov-y able in one direction for rotating said sec ond shalt, and means for automatically disconnecting said shaft, and its rotatingmeans when the shalt is rotating in the opposite di:
