IMPROVEMENTV IN CAR-STARTERS.

To all whom it mayconccrn: i

Be it known that I, HENRY ScHREINEe, of the city and county of Philadelphia, in the 'State of Pennsylvania, have invented certain new and useful Improvements in Car-Starters, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings, in Which- Figure lis a top view of a car-bottom having my improvements attached. Fig. 2 is a bottom view of the same. Fig. 3 is a vertical longitudinal section, taken through line uw of Fig. l. Fig. 4, Sheet No.2, is a side view of the lever D on an enlarged scale. Figs. 5 and 6 are a like view and cross f section of the -ratchet-wheel E. Fig.7 is an isometrical view of a pawl, G. Figs. 8 and 9 are side and edge -views of the shield R. Fig. 10 is a modied form of the double, sector J J Like letters of reference in all the figures indicate the same parts.

My invention, in the first place, relates to a sector-lever whichlits looselyon the front axle between two ratchet-wheels, which are permanently connected with the. axle in con1bination with a double sector, parallel with and beneath the bottom of the car. The double sector has a groove in each arc, one for the the draft chain or rope, andthe other for a chain, rope, or belt, and which connects the sect-or with the above-mentioned sector-lever, the said connecting-chain passing over suitable pulleys to form the connection. When the draft chain or rope is pulled forward by the horses in starting, the sector-lever, by means of its connection with the double sector, as described, is turned partly around to assist in starting the car, the lever being pro'vided with pawls, (011e on each side,) which engage with` ropes, belts, or wires.

then the sector has a backward movement the proper position for the next starting of theV car.

' A is the bottom of a street-car. B is the. front axle, and B the rear axle. C G are the traction-wheels.4 D is a sector-lever which fits loosely on one end of the front axle B, between ratchet-wheels E and E. The lever D is provided with pawls Gr Gr, which are hung to its sides by means of the pin c. The lever has grooves b b' in its periphery1 to receive chains, The groove b receives the chain H,one end of which is fastened to the rear edge of the lever. The said chain is passed around the pulleys I I, (seen in Fig. 2,) and lies in the groove d, in the long end of the doublesectorJ J', which works on the fulcrum-pinf, the upper end of. which is fast in the bottom A of the car, and the other end held by the bow K, which is fastened to the lower side of the bottom of the car. rlhe draft-chain L is held in the groove d', in the periphery of the short sector J', one end of the chain being fastened to the rear edge of the sector, and the other passed through the eye ot' the bolt` h, or between two rollers. The frontend of the chain L is connected to the double-tree, (not seen in the drawings.) 1n

`order to cause the double-tree to move for` ward in front of the car only about fourteen inches while the car advances about twentyone inches, the short sectorJ, to which the draft-chain is attached, is one-third shorter than the sector J, which connects with the starting sector-lever D.

`I do notI confine myself' to the size or proportions of the sectors, as above stated, as they may be varied to suit the size and shape of the car, or the distances to be moved on the track. When the lever isdrawn to its forward position by the-movement of the double sector acting upon it by means ofthe con necting-chain H, the pawls Gr Gare disengaged from the ratchetwheels E and E', and the lever is brought back to its former position (seen in the drawings) by means of the weighted sector N, on the shaft O and the rope P, one end of which is fastened to the sector, and the movement of the car.

other end to the front edge of the lever. the chain lying in the groove b. As this function may be readily performed by some other device, I do not confine myself to the use of the counter-weight.

As the lever arrives in this position, the pawls are drawn onto the resilient ends of' the springs Q Q, to elevate them above the ratchet-wheels, and thus admit of the backward I do not coniine myself to the form of the double sector as shown in the drawings, as various forms are necessary according to the position in which the directing-pulleys may have to be placed, governed by any dii'erence in the construction of the car, one of which is shown in Fig. l0.

To prevent the pawls G G rattling in their backward movement over the ratchet-wheels E E', a strip of leather or india rubber, or a piece of wood, K, or other soundless material, is connected by means of a dovetail groove with the lower edge of each pawl G, as seen in Fig. 7, or the strips may be fastened by means of screws, or in any other convenient manner. A similar result may be accomplished by means of bent wires l, connected with the ratchet-wheels, as seen in Fig. 6, so arranged as not to be in the way of the action of the pawls, and so that the latter may slide on them in their backward movement.

The ratchet-wheels E and *".are made in halves, for conveniently connecting them with the axle B 5 and for conveniently connecting the sector-lever D with the axle, I make it with a .detachable block, m, held by means of a bolt, n, as seen in Fig. 4. Instead of the block an ordinary cap may be used.

To prevent mud or dirt falling on the ratchet-wheel E' from the upper edge of the contiguous traction-wheel C, I connect the shield R with the bottom of the car, as seen in the drawings. The shield is shown in detail in Figs. 8 and 9.

I claim as my invention- '1. The combination of the sector-lever D, chain H, guide-pulleys I I, double sectorJ J', and draft-chain L, substantially in the manner and for the purpose set forth.

2. The soundless strip K, connected with the under side of the pawls G- Gr, substantially as and for the purpose set forth.

3. The weighted sector N, having a rope, P, in combination with the sector-lever D, for giving a reverse movement to the lever, substantially as set forth.
