Application filed May 28,1888. Serial No. 275,380. (No modelfi.

T (tZZ whom, it 71103 concern:

Be it known that we, \VILLIAM PARKS AKERs and Joan COLLIER Lnvnsnv, J12, both of Jacksborough, in the county of Jack and State of Texas, have invented a newand Improved Oar-Starter, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved car-starter adapted for all IO kinds of cars and vehicles, being speeiall y of great-value on grades.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a car provided with the improvement, parts being in section. Fig. 2 is an end elevation of the same. Fi 3 is a plan view of the same. Fig. 4 is an enlarged sectional plan view of the same on the line .90 0c of Fig. 1. Fig. 5 is a sectional side elevation of the improvement on the line y 1 of Fig. 2. Fig. 6 is a perspective view of the crank-arm, and Fig. 7 is a sectional end elevation of part of the improvement on the line 2 z of Fig. 3.

The car or vehicle A, of any approved construction, is provided with the usual axles, B B, carrying the wheels 0 O. On the rear axle, B, is held loosely a sleeve, D, provided with a ratchet-wheel, D, engaged by a pawl, E, fulcrumed at E to the car A and pivotally connected by a link, E to a lever, F, fulcrumed on the car A and operated by the driver or conductor of the car. On the front face of the ratchet-wheel D is formed a spiral cam, D on which operates the block 1, held to slide transversely in a wheel, G, secured to the axle B of the car. The outer end of the blockG is provided on top with a shoulder, G engaged by annular .tl ange H, formed 011 the lever H, fulcrumed on the bracket H attached to the car A. A spring,'H is located between the lever. II and the bracket H and serves to press the flange 11 against the wheel 50 G, so as to hold the block G in its innermost position. To the upper end of the lever 11 is on the disk L.

secured a rope or red, H, for moving thelcver toward the bracket ll. to disengage the block G from the cam D The rope or red H extends to a brake-staff on the car to be operated 5 5 conveniently by the operator whenever desired.

To the other end of the sleeve D is secured or on it is formed a gear-wheel, I, meshing into a gear-wheel, J, fastened on a shaft, J, mounted to rotate in suitable bearings, K, fastened on the inner face of the disk L, mounted to rotate loosely on the sleeve D. Tothe disk L is secured a ratchet-wheel, N, which has its bearing 011 the sleeve D, and between the said ratchet-wheel N and the disk L is held a coiled spring, 0, fastened by one end to the said disk L and by its other end to the sleeve D.

The ratchetwheel N is engaged by a pawl, N, pivotally connected with the arm N fulcrumed on the car A. On the pawl N is pivoted the semicircular arm N which passes through the arm N the center of the said semicircular arm N being in the pivot of the pawl N and the arm N A spring, N, is coiled on the said semicircular rod or arm N resting at one end against the said pawl N and at its other end against the said arm N and having the tendency to hold the said pawl N at its other end against the said arm N in a straight position, as shown in Fig. 5. The arm N is connected by-a link, N to a lever, N, fulcrumed on the car, which lever serves to raise said arm, so as to disengage the pawl N from the ratchet-wheel N whenever the operator desires to do so.

The shaft J, before mentioned, carries a bevel gear-wheel, P, which meshes into a bevel gear-wheel, Q, secured on a screw-rod, R, held by one end in a bearing, K, secured on the disk L, and the other end of the said screwrod R engages a threaded block, S, held to slide radially in a suitable groove, L, formed The block S is adapted to engage a wrist-pin, T, held adjustably in the crank-arm U, fastened 011 the axle B. Said wrist-pin T is adapted to engage a notch, L formed in the periphery of the disk L next to the groove L, in which the block S slides. The wristpin T is held to slide in a slot in the crank-arm U, as is plainly shown in Fig.

6, and the outer end of the said wrist-pin is provided with an outwardly-extending arm,

T, against which presses one end or"; a coiled spring, T pressing with its other end against the projection U, formed on the crank-arm U. The coiled spring '1" has a tendency to press the wrist-pin T inward. On the extreme outer end of the wrist-pin T is secured a plate, T, provided with one inclined. edge, as shown in Fig. (3.

The bottom of the plate T is adapted to rest on an arm, V, t'ormed on the upper end of a spring, V, secured to the crank-arm l Said plate T is also adapted to engage a notch, V formed in the said arm V of the spring V, and the extreme outer end of the said spring-arm V forms a bevel, V adapted to be engaged by the face of a ring, \V, formed on a lever, \V, iiulcrumed on a bracket, W, secured to the car A. A spring, W, is placed between the bracket W and the upper end of the lever \V, so as to hold the ring \V out of contact with the bevel V A cord or red, \V", is connected with the upper end of the lever \V and extends to the driver or conductor, and is operated by the same.

The operation isas follows: When the plate T of the wrist-pin T rests on the arm V of the spring V, as illustrated in Fig. (5, the said wrist-pin T is disengaged from the notch L of the disk L. \Vhen the car A new travels in the direction of the arrow (1, the crank-arm U rotates with the axle B without engaging the disk L by means of its wrist-pin T, so that the latter,with the sleeve D, remains inactive. Now, when the operator desires to wind up the spring Oat the downward movement of the car on a grade, for instance-the operator pulls on the rope or cord so that the lever \V swings and causes its ring V to press the bevel V outward, so that the spring-arm V is moved outward, whereby the plate passes into the notch V and the spring T forces the wrist-pin T inward until the outer end of the wrist-pin T is brought in close contact with the periphery of the disk L and engages, finally, the notch L of the disk. The latter is then rotated by the movement of the crank-arm U and its wrist-pin T in the direction of the arrow Z), whereby the spring 0 is coiled up, and a return. movement of the disk is prevented by the pawl N engaging the ratchet-wheel N, connected with the said disk L. hen the disk L commences to rotate, the gear-wheel J also commences to rotate on account of being in mesh with the gear-wheel I, held on the 110w stationary sleeve D. The rotary movement of the gear-wheel J imparts a like movement tothe gear-wheels P and Q and to the screw-rod 'R, whereby the latter imparts an outwardly-sliding movement to the block S. \Vhen the spring 0 is nearly wound up, the block Scomes in contact with the wrist-pin T, and finally lifts the latter from the notch L of the disk L, and the spring-arm V again assumes its former position, so that the bottom of the plate T rests on the top of the arm V of the spring V, as shown in Fig. (5, the operator having prevt ously released the rope or cord \V. The wristpin T is then completely disengaged from the disk L and rotates with the crank-arm U and the axle B without touchingthe disk L. The spring 0 is held wound up, as the disk L is prevented from a return movement by the pawl N, before mentioned, and the sleeve D, to which the other end of the spring 0 is secured, is also prevented from rotating as long as the pawl E engages the ratchet-wheel D, formed on the said sleeve D. \Vhen the car now travels up a grade, or is starting after having stopped, and the operator desires to utilize the force of the wound-up spring 0, he operates the erankleverl so that the pawl E is thrown out of contact with the ratchet wheel 1). The coiled spring 0, by exerting its pressure against the sleeve 1), causes the latter, as the disk L is held stationary, to retate in the direction of the arrow 1), and as the said sleeve is connected with the axle B by the block G, held in the wheel G, and against the cam D of the raehet D, the said axle l3 receives the force of the coiled spring 0, whereby a forward movement in the direction of the arrow (1 is given to the car A. By the unwinding of the spring 0 the block S is returned to the inner position. \Vhen the car runs backward and the force of the wound-up spring is to be utilized to assist in running backward, then the operator pulls the rope ll", so that the lever H, with .its annular flange H, moves the block G outwardly until the latter disei'igages the spiral cam D on the ratchet-wheel I), thus permitting the car A to run backward without hinderance, as

the movement of the wheel G, secured on the axle B, is not transmitted to the ratchet-wheel D on account of the block G being disengaged with the ratchet-wheel D. The operator then pulls the cord \V", which causes the wrist-pin T to come in close contact with the periphery of the disk L, but does not engage the notch L on said disk, because it moves backward over it. The pawl N is then raised out of notch on ratchet-wheel N, which allows the disk L to be turned backward until the notch L engages the wrist-pin T, thereby assisting to the extent of the full force of the spring in the backward movement of the car. When the operator, however, desires to wind up the spring 0 on this backward movement of the car, he slackens the pull 011 the cord or rope H", so that the spring H forces the block G inward to engage the cam D whereby the ratchetvheel D and its sleeve are turned in the inverse directions of arrow 1) and the spring 0 is wound up. \Vhen the force of the wound-up spring is to be utilized, the operator proceeds the same as above described.

Itis understood that any desired number of such devices may be employed on one axle or on both axles, as desired. hen the spring 0 is unwound, the operator drops the pawl E again into contact with the ratchet-wheel D, and when the operator again desires to coil the spring 0 he operates the lever V, as before described, and the same operation is repeated.
