CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 250,C33, dated November 22, 1881,

Application filed June 17, [881.

T a all whom it may concern:

Beit known that l, W. E.YOUNG, of the city of Chicago, county of Cook, and State of Illinois, have invented certain Improvements in Car-Starters, of which the following is a specification.

The object of my invention is to provide a street-car with devices and combinations of devices by means of which the driver may exert apart or all of the force necessary to start the car, and do this quickly and easily. I have accomplished this object by means of the parts and devices hereinafter described, with reference to the accompanying drawings, in Which- Figure 1 represents an inner face view of one of the carrying-wheels, a longitudinal section of a part of the floor, and a cross-section of one axle of a street-car, together with an elevation of the cap D, its shells, a shaft, S, and other parts; Fig. 2, an edge view of cap D,aninnerview ofcap 0, and other parts; Fig.3, a section of Fig. 2, taken as indicated by the broken line 3 3 in Fig. 2; Fig. 4, a back view of the cap 0; Fig. 5, a horizontal central section of toothed disk E, cap D, cap 0, and other parts; Fig. 6, a detail view of the hanger G; Fig. 7, a perspective of one edge of cap D and one ofits protuberances, g, the pin for the hanger, and other parts.

The toothed disk E may he made of any suitable size and thickness, and mayhave a plain face or a dished face to correspond with the face of the carrying-wheel. It is provided on its inner face and upon the outer edge ofsame with bevel-gear to correspond with the form of bevelpinion E, which is designed to operate upon it. It is also provided with a projecting hub, e,fitting arouudthe axle C. The shell of frame D is also circular in form, covers and incloses the inner face of the disk, so as to exclude mud and slush and make room for certain parts within it, and is provided with a hub, 6 like that of the disk, but larger and shorter, so as to slip over hub e and be held in place by collar 0 which is held in position by set-screw s which holds it and hub a fast upon the axle C. The shell or frame D is provided with flanged edges extending over beyond the outer face of the disk, so as to exclude dirt and slush from the (No model.)

bevel-gear iuclosed, the bevel-pinion E, and other parts. The shell is also provided with an upright arm, t, that passes up through the floor A and serves to hold it stationary, and it also serves as a fulcrum to the geared leverage, by meansofwhichthecarisstarted. Atbothends of its horizontal diameter the shell D is enlarged at d and cl, for the purpose of inclosing the operating devices and excluding dirt. The flanged rim is cutoff atright angles with its diameter-across the enlargementsdandd,leaving flat edge surfaces, from the upper portion of which project pins g. The pin 9 in each enlargement supports a swinging hanger, G, the upper hole. g, in which is made oblong, as shown in Fig. 6, in order that the hanger may have some play-room lengthwise when upon the ping. The lower end of the hanger is provided with a round hole, through which the shaft S is passed, and upon which pinion E is placed and held by a spline against turning thereon, as shown in Fig.2,so that the shaft may have someplay lengthwise in the pinion. Atoothed pawl, It, is pivoted in a depression made for it in thelower portion of the enlargement (Z back of and beneath the pinion E. Capcis bolted to and completely covers the openingof the enlargement. It has a curved slot, f, through which passes and swings the shaft S. One portion of the rim of this cap 0 projects back of the disk E, to serve as a stay to prevent the shell and disk from spreading asunder when the gears are operated.

The shield 0, pivoted to cap 0, as shown in Fig. 3, fits closely around the shaft S, and serves to cover the unfilled portion of slot f and exclude dust and dirt. The shaft Sextends out from the shell or frame D, forward immediately under the brake-staff, where it is supported by a suitable bearing depending from the floor or platform. To its outer end is securely fastened the bevel-gear P. The lower end of the brake-staff turns in a suitable socket provided for it in the bearing, as shown.

The bevel-gear P is held to the staff B against turning by the spline K, but has ver tical play, in order thatitmay be readily moved into and out of gear with pinion P. Itis held up out of gear with it by spiral spring Q, and

depressed into gear with it by rod T, whichis attached to it and extends up through floor, and is operated by the foot of the driver. The upper portion or hub of this gear P is provided with teeth, so as to form part of a clutch. On the brake-staff B, between this gear and the floor, is a sleeve, J, to the upper end of which is fastened the brake-chain, while the lower end is toothed to correspond with the hub or pinion P, and form with it a clutch. The lower end of the sleeve is enlarged, so that its outer edge is provided with the teeth for clutching, while the inner edge is plain next the statt', and forms a ring or shoulder, which rests on the upper end of the spline K, and thus the sleeve is held up in place and allowed to turn freely and independently when the gear is depressed.

The operation ot'the hereinbefore-described parts and devices may be described as follows: The spring Q naturally holds the gear I? up in connection with the sleeve J, so that when the brake-handle is turned the chain is wound up and the brake applied. The brake may be released either by allowing the brake-handle to turn around in the reverse direction or by depressing the gear P by means of the rod T. \Vhen the gear P is depressed into connection with gear P and the brake-handle turned ahead the pinion E, revolving with the shaft S in the direction indicated by the arrow in Fig. 2, engages with the toothed pawl B, which, turning on its pivot, throws the pinion in the di rection of the disk E, and when the pinion reaches and meshes with the gear of the disk (the brake-handle still continuing in motion) its tendency is to run around up that gear, which it does do, thereby freeing the pawl It, which then drops back into its former position. The pinion runs up the gear until the shoulder a on thehangerG meets a corresponding shoulder, n, on the cap 0, which stops the swing of the hanger G. Now, if suflicient force is exerted upon the brake-handle, the disk E must turn, and with it the axle G and wheel B, and thus will be accomplished the object of my invention.

The larger the toothed disk may be theless the power required to turn the axle and start the car.

In the foregoing specification I have confined the description to the operative parts, and have shown but one wheel and one axle in the drawings.

The devices in enlargement d are a duplication of those in enlargement d, and may be used when the car is to be run with the other end foremost.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the shaft B, having the spline K seated therein, as described, and the loose sleeve J, having its lower end so enlarged that its outer edge provided with teeth T will form a shoulder within the circle ofsuch teeth to rest upon the top end of the spline, the whole adapted to hold the sleeve up out of the way whenever the said shaft may be used to operate the starting devices, substantially as described.

2. The combination of bevel-gear P on shaft S with bevel-gear I on thelower endot' shaft B, spring Q, and foot-lever T, adapted to throw said bevel-gears into mesh and out of mesh with each other, in order to either revolve shaft S or to brake the motion of the car at the will of the operator, substantially as described.

3. The combination of the bevel-gear P, shaft S, pinion E, pawl It, and hanger Gr,substantially as and for the purpose described.

4. The combination of the hanger G and the cap 0, constructed substantially as and for the purpose described.

5. The oornbination of pawl R with pinion E, hanger G, cap a, and the geared disk E, substantially as and for the purpose described.

6. The (JOll'lblllZltlOIl of shell .D, having the enlargements d and d, with the geared disk E, substantially as and for the purpose described.
