AUTOMATIC ENGINE-STARTER.

To all whom it may concern:

Be it'known that I, WILLrAM- .l. J. ODEA, a citizen of the United Stateaiesiding at Buffalo, inthe'county of Erie and-State of New York, have invented certain new and useful Improvements in Automatic Enginesimple, durable, and powerful starting-device in which i the parts are reduced to a minimum, and in which power may be stored by the action of the engine, and

released at will by the manipulation of a lever withinconvenient reach of the operator. My invention consists in the construction, arrangement, and combination of parts to be hereinafter de-.

scribed and particularly pointed out in the subjoined claims.

In the drawings,Figu re l is a side elevation of the device.

taken'online xx, Fig. 1, the parts being shown in the position they assume when starting an engine. Fig. 4 is a similar view, the parts being shown in the position they assume when. storing power. Fig. 5 is a. vertical section taken'on line y'y, Fig. 2. Fig. 6 is a side elevation of the gear containing the power-spring, the inner end of the'latter and the'shaft passing through the casing being shown in section. Fig. 7 is a transverse section taken on line'z 'ajFig. 4. Fig. 8 is sn enlarged sectional view showing the manner of securing reference refer to like partslin the several figures any desi rable construction and outline; it serving simply tosiiiipdrt-the variotis 'parts of the device. Revolubly mounted in a fixed location in said frame is a shaft B which maybe the engineshaft or a shaft having connection with the engine-shaft; but which will, for convenience, be hereinafter referred to as the engineshait: Secured to said engine-shaft are two gear- -wheels 0 and B, one of which-is adapted to bebrought into mesh with a gear-wheel E securd to a shaft F which I will term-stile ipower-shaft. Saidshaft is .mounted in bearings e-slidahle' within-longitudinal slots G formed in the frame. Interposed between said bearings and the ends of the slotsnearer theengineshaft are springs H thafiserve to normally maintain said bearings at the opposite ends oi said slots. One end oi seid yieldingly-niountedshaft is reduced in diameter, as at I, to form a shoulder and loosely mounted on said'reduced' portion of the shaft is an eccentric bushing J; it being held from lengthwise Specification of Letters liatent. Application filed September 7,1905. serial llo. 277,448.

movement on the shaft by said shoulder and by a collar j secured to the end of the shaft and journaled in one of the bearings e, said collar serving as a journal for said shaft.

At the outer end of the bushing is a reduced portion K having its circumference concentric with the shaft, and having secured thereto a .pinion is by means of which: the bushing is revolved. A lever L ispivotally,

attached between its ends to a cross-bar L mounted in the frame, and at its lower end said lever has a gearsegment Z whichisheld in mesh with the pinion k. Said lever, on being rocked, causes said pinion to revolve and consequently the bushing .I to which said pinion is secured. Mounted loosely on said bushing is a gearwheel M having an annular ratchet-rim'm. Said gearwheel is held against longitiidinal movement on said bushing by a flange 9" formed on the inner end of the latter and by a collar N secured to said bushing and bearing against the hub of said gear-wheel. Within said'ratchet-rim is a convolute power-spring 0 having one end thereof secured to a pin 0 projecting from shaft F and its other end secured to the inner side of said rim.

Said pin is notched at 0 and provided with an inclined end 0 The inner end of spring 0 is provided with an elongated opening 0 having its inner endbeveledu The metal of the spring between the end thereof and the outer end of said opening enters the notch in the pin, said notch serving to securely hold the spring to the pin. In the. event of the engine'reversing while the startingdevice is in connection therewith, the inner end of the spring becomes disconnected from the pin by reason of the beveled inner end of opening 0 riding up the inclined end of said pin, thereby avoiding injury being I done to the starting-device; the spring automatically The letter A designates the frame whichinay be of engages the pin when the engine is given a proper start. I

to prevent unwinding of the power-spring. A dog R is also loosely mounted on the barLf and engages gearwheel E to prevent turning of theshaft F. 'It is therefore apparent, that said pawl and dog'act' to maintain the power-spring in its-wound-up condition.

S designatesa foot-lever which is, pivoted at its lower end, to the frame and has one end of a rod s pivotally connected thereto; the other end of said rod being pro- .vided with an eye through which shaft F extends: In

this manner said shaft is free to revolve while maintainingconnectionwith said rod. A secondrod T is pivotits opposite end passed through a perforated upstanding lug formed on the dog R; the extremity thereof being enlarged and adapted to be brought into contact with any connected at one end with the foot-lever and has bearing against pawl P and dog B, respectively, it serving to normally maintain them in locked position.

In applying the device the spring is coiled up and ing its eccentricity as described. vWhile the teeth of gears E and D are being intermeshed, the head or enlarged end of rod/l comes .in contact with dog R and releases same, thereby permitting the unwinding of the powerspring, which serves to revolve the engine-shait and start the engine. When the engine is started, the foot-lever is released to permit the parts to be returned to normal. 'After the engine is started, the lever Lmay be actuated to revolve the bushing .l and thus bring the eccentricity of the bushing tothe opposite side of the shaft, which changes the center oi gear-wheel M with -reference to the axis of shaft F.- I The gear-wheel M is 5 thus moved forward into mesh with gear-wheel C 0n the engirie-shait, to cause .the power-spring to be recoi'led for the purpose of storing power. i The lever L may now be returned to normal to movethe gear-wheel M out of mesh with its codperating gears. From the foregoing,

- it is understood that the gear-wheels are arranged in pairs, which, however, are normally disengaged, and

that one of each pair is secured to the engine-shaft and the other carried on the yieldingly mounted shaft.

, This invention is susceptible to changes in form, con- ""strue tionand arrangement of parts, without departing frbm my invention or sacrificing any of th advantages thereof.
