CAR-STARTER.

SPECIFECATION 'forming part of Letters Patent No. 307,569, dated November 4, 1884.

Application led June 16, 1884.

the city and county of Camden, State of New Jersey, and DANIEL Genn, of Millville, in the county of Cumberland, State of New Jersey, both citizens ofthe United States, have in vented a new and useful Improvement in Car- Starters, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figurel isatop or plan view of a car-starter embodying our invention. Fig. 2 is a vertical section thereof in line :c x, Fig. l. Fig. 3 is a transverse section in line y y, Fig. l.

The remaining figures are views of detached parts on an enlarged scale.

Similar letters of reference indicate corresponding parts in the several figures. i

Ourinvention consists of certain improvements in a carstarter, as will be hereinafter fully set forth and definitely claimed.

Referring to the drawings, A represents the truck of a car, and B represents the longitudinally-extending drum or casing, which is secured to the under side of the truck or truck frame, and contains a series of coiled springs, C, which are attached to said casing and to a rotary shaft, D, which latter is mounted on the plates or bearings D.

Connected with the shaft D is a bevelwheel, E, and connected with the axle A are bevelwheels F, with either of which the wheel E is adapted to engage, the shifting of said wheel n E being accomplished by attachingr the drum or casing B to the truck by means of a pivot, Gr, which is secured to a hanger or bearing or `f nie, A, beneath the truck, and permits the drum to be oscillated to the right and left, whereby the wheel E may be moved toward and from either wheel F, as is evident.

To the shaft D is fixed a ratchet, H, the engaging-pawl H whereof is hung on the end of the drum or casing B, and has connected with it one end of a chain, H, whose other end is secured to the frame ofthe truck, as at a.

J represents a crossbar, through which the shaft Dis passed, the ends of the saine being movably supported on ledges J, projecting horizontally and inwardly from the frame A.

(No model.)

Above the ends of the cross-bar are rising and falling blocks K, which are fitted to the sides of the frame A, and have their inner faces Y stair-shaped for locking with the ends of the cross-bar rela-tively to the position of the latter, it being noticed that said cross-bar moves with the easing B either tothe right or left, or may occupy a central position relatively to the location of the bevel-wheel E.

Connected with the blocks K, on the upper side thereof, are hooks L, with which engage arms M, the latter being secured to a rockshaft, N, which extends transversely and has its bearings on the frame A. In order to operate said shaft N, and thus raise the arms M, and consequently the blocks K, so as to release the ends ofthe cross-bar J, there is connected with said shaft a crank arm or wheel, N, to which is secured a rod, P, the forward end of which is attached to a treadle, P", the latter being properly mounted on the truck and within convenient reach of the car-driver.

To opposite sides of the frame A, and located below the shaft D, are pivoted levers Q, whose outer ends are connected with the blocks K by means of upright rods or pins K. These levers Q are adapted to be depressed, and thus raise the blocks K, by means of alug or finger, It, which is secured to a hook-shaped cam, S, the latter having a threaded opening, which is fitted on the threaded portion b of the shaft D, so as to travel thereon.

Fastened to the shaft D adjacent tothe `cam S is a collar, S, which is adjustably held in position aud adapted to rotate with the shaft, and at a certain time have the cam abut against it and cause the rotation of the cam,whereby the finger R is carried around to the levers Q and caused to depress the same, thus raising the blocks K, as hereinbefore referred to.

To the upper end of the piece A of the .frame A is pivoted a toot-h, T, whichis so hung that when the rotating and moving cam S reaches said tooth T the latter then engages with a shoulder, c, on the back of said can). On a cross-bar, T, of the frame A is a pin, T, which is so disposed that when the cam S reaches said pin it takes hold of the same, and thus draws with it the casing B and connected 2 Y i p 307,569

the opposite direction, and thus in the direc-k tion from the other bevel-wheel F, also placing the wheel E free between the wheels F, the operations of the cam S with either the pin T or abutment T depending upon the direction in which the frame A is at the time of the engagement of the cam S.

In-order to move the casing B and connected parts, which,`as has been stated, has a pivotal connection with the truck-frame, we employ an elbow-lever, U, which is pivoted to the frame A, and is connected with one end of a rod, IJ', whose other end is connected with a lever, U, the latter being mounted on the truck-frame convenient to the car-driver, it being evident 4that the operation of the lever U in reverse order serves to operate the casing -B i-n reverse directions, thus shifting the bevel-wheel E fromeithcr of the bevel-wheels F when so required.

The operation is as follows: The treadle P is depressed, thus rotating the roclrshaft N and-operating the arms M, which-act against the hooks L, and thus raise the stair-shaped blocks K, releasing the cross-bar J, and allowing the frame A and connected parts to be moved. This is done by operating the lever U", wh-ich, moving the rod U, turns the elbowv lever U, and so throws the frame A to one side or the other, thus putting the bevel-wheel Ein engagement with one ofthe bevel-wheels F. As `the car continues to move, the shaft D 2is rotated, and thus the springs are wound, the pawl H and ratchet-wheel H serving to lock yor retain the spring in a wound condition. As the shaft D continues to rotate, it causes the cam S to travel toward the collar S. When the cam S comes in contact with the collar S, the latter causes the cani to rotate with the shaft- D. As the cam now rotates, the finger R strikes the levers Q, and thus raises the blocks K. The-cam now comes in contact with vthe vpin T or abutment T, according to the 4 position ofthe frame A, and so moves the wheel E clear of the wheels F. The power stored in the springs C is retained through the pawl H and ratchet-wheel H. In order to utilize this power when so desired, the treadle I is again operated and the lever U moved in opposite direction to that described above. This throws the wheel E in engaging contact with the other wheel F, so that the power'of the spring may be transmitted through the wheels E F to the axle A, and so to the truck-wheels. The chain H is of such length that when the frame A is moved into its second position it causes the pawl H to be held free of the ratchet-wheel H, and thus no longer controls the springs C. As the cam S may be so tightly forced against the collar S that it will be carried in a backward direction, and not ride freely on the thread b of the shaft D, I provide the tooth T, which, as the cam S comes around, engages the same at the shoulder cof the cam, and starts the latter backward on the thread b, and places it in position for the next operation of winding the springs.

Since the meshing of the bevel-wheels may at times be hard to accomplish, owing to the position of their teeth, we form (see Figs. 7, 8, and 9) in the bore of the wheel Fr a seg- -mental recess, d, in which the key e is free to move. Secured to the wheel is a spring, f, which has its free end in a collar, E', attached to the shaft D. The teeth are formed somewhat in the shape of a wedge at their outer end, (see Fig. 9,) and thus by the wedging action of the teeth and the slight play of the wheel E on the shaft D we Vare enabled to readily and reliably place the wheels in operative contact. The latter feature, however, may be embodied in another application for Letters Patent.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-
