UNITED STATES PATENT OFFICE.

JOHN C. ELLIOTT, OF RITTMAN, OHIO.

CAR STARTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No. 335,217, dated February 2, 1886.

Application filed April 9, 1855.

To all whom it may concern:

Be it known that I, J. O. ELLIOTT, of Bittman, in the county of Vayne and State of Ohio, have invented certain new and useful Improvements in a Combined Car Brake and Starter; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification, in which- Figure 1 is a bottom .plan view of my improved car-starter. Fig. 2 is a vertical section of the same on line aa", Fig. 1. Fig. 3 is a transverse vertical section on line 3/ y, Fig. 1. Figs. 4 and 5 are details of the ratchet-andpawl devices.

This invention relates to improvements in car-starters in which the action of the brake gives tension to the springs that actuate the starting mechanism; and it consists in the construction and arrangement of the various parts hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, A represents the car-truck,composed of the usual side frames, a, in which the axles B B have bearings, and the central transverse beams, A A.

b b are the wheels, of usual construction; and

C is a rectangular frame, lying longitudinally within the truck between the beams A and resting and moving laterally on the lower on thereof.

C O are longitudinal side arms on the front and rear ends of the frame 0, forming part therewith, and having secured to their lower edges the semicircular loops 0 c, for a purpose hereinafter explained.

D are disks secured to the axles to the inner side of the wheels on one side of the truck, and D D are similar disks on the other side of the truck. The inner surfaces of the disks D D are preferably made concave, as shown.

E are collars surrounding and turning freely on the axles on one side of the truck, and E are similar collars on the other side. Each collar has a circumferential groove, a, into which a loop, 0, enters.

F are disks on the outer ends of the collars E, and F are similar disks on the outer ends of the collars E. The said disks have their Serial No. 161,719. (No model.)

outer surfaces convex to engage against the concave surfaces of the disks D and D.

G are ratchet-wheels formed on the collars E between the disks F and grooves e, and G are similar ratchet-wheels formed on the col lars E. The ratchet-wheelsG have their teeth pointing in the opposite direction to those 01' the wheels G. In other words, the teeth of the ratchet-wheels on one side point in a reverse direction from those on the other. ratchet-wheels G are permitted to rotate in one direction only by the pawl-arms H, haw ing their upper ends pivoted to the outersurfaces of their arms 0 on one side of the frame 0. and engaging the ratchet-wheels by means of the springs g, aided by gravity. The ratchet-wheels G are permitted to rotate only in the direction opposite to that of G by their pawl-arms H, pivoted to the arms C on the opposite side of the frame from the ratchetwheels G. The pawls H engage the ratchetwheels G by means of springs g, aided by gravity, as is evident from the drawings. The disks F F,at either end of the truck,are aless distance apart than the corresponding disks, D D; hence when the lateral motion of the frame 0 makes the disks F engage the disks D the disks F and D will he disengaged, and the reverse.

The inner facing ends of the collars E E at either end have secured to them circumfereir tial bands I, which project inward from the ends of the collars and lie around the ends of a cylindrical core, K, so as to support and turn freely thereon. The said core surrounds the middle part of the axle, which turns freely within it. M is a coiled spring, which turns around said core, and has its ends secured to opposite bands I.

The frame 0 may he slid laterally by leverarms X, pivoted each to an end of the truck, or by other suitable means.

The pawlarms H H may, if desired, he pivoted to the inner surfaces of the arms 0, and may engage ratchet-wheels made as de scribed, but on the inner ends of the collars.

The bands 0 support the collars E E and cores K, and the lateral motion of the frame 0 moves said collars, cores, and disks F F laterally with it.

Vhen the truck. is moving in the direction The in which the ratchet-wheels G arepermitted to rotate by their pawl-arms H, and the frame is moved laterally, so as to engage the disks F against the disks D, the former disks act as I brake-shoes to the latter, and the latter cause the former to rotate with them until they cease to move. The ratchet-wheels G are also rotated under their pawl-arms H, thereby winding up or increasing the tension of the springs M between the collars E E. As the ratchetwheels G cannot rotate in the same direction as the ratchet-wheels G, and as the latter cannot reverse their motion, the springs remain under tension. By allowing the disks F and D to remain engaged and releasing the ratchet-wheels G the tense springs will start the car in the reverse direction; but by engaging the disks F D and releasing the ratchetwheels G the car will be started in the direction it was going when stopped." The disks F F and D D thus, besides acting as brakes, also by their contact cause the axles to rotate when the springs act. By releasing both ratchet-wheels at each end of the truck the springs are released from tension without starting the truck in either direction. The levers X are arranged one at each end of the truck for convenience,and are connected by a system of links, z, to the frame 0, that the latter may be actuated from either end of the car.

When the car has arrived at the end of its course and the brakes applied by a lever, X, the team maybe attached to the other end, 5 and the proper pawls disengaged by the foot, so as to start the car in the reverse direction. Instead of the frame (1 resting and sliding on the-truck of the car, as described, it may be suspended from the bottom of the car-body 40 in such manner as to allow of the proper lateral motion for braking, and yet prevent the cores K, collars EE, and disks F F from resting their weight on-the axles. This would be the construction used in street-cars.

Having described my invention, I claim 1. In a combined car brake and starter, thecombination, with an axle, two collars turning freely and sliding together thereon, a frame lying between the wheels and provided with bearings in which the collars rotate, and detents connected to said frame and which when acting allow the collars to rotate in opposite directions only, of a coiled spring uniting the inner ends of the collars, and two brake-clutches adapted to lock the outer ends of the collars with the axle, the one clutch being disengaged by the same motion that engages the other, substantially as specified.

2. In a combined car brake and starter, the combination, with an axle, two collars turning freely and sliding together thereon, aframe lying between the wheels and provided with bearings in which the collars rotate, and de tents connected to said frame and which when acting allow the collars to rotate in opposite directions only, of a coiled spring uniting the inner ends of the collars, two brake-disks, one on the outer end of each collar, and mechanism, substantially as described, by which one brake-disk is engaged against a disk secured to the axle by the same motion that disengages the other brake-disk from another disk secured to the axle, substantially as specified.

3. In a combined car brake and starter, the combination, with the axle B, wheels I), and disks D D, of the frame 0, coiled spring M, collars E E, arranged to turn freely on the axle in bearings secured to the frame 0, and to slidewith said frame upon the axle, and controlled by detents attached to said frame, which detents when acting permit them to rotate in opposite directions only, and the disks F F, respectively secured to the outer ends of th-e'collars E E, substantially as specified.

4. In a combined car starter and brake, the.

lars E E, provided, respectively, with the disks F F, and ratchet-wheels G G, substantially as specified.

In testimony that I claim the foregoing as J. o. ELLIOTT.
