CAR-BRAKE.

[SPECIFICATION forming part OLetters Patent No. 375,841. dated January 3, 1888 Application tiled August 25, 1887.

To all whom, it may concern:

Be it known that l, JAMES K. I?. TIMMoNs, a citizen of the United States, residing at Timmons, in the county of Murray and State of Tennessee, have invented a new and useful Improvement in Car-Brakes, of which the following is a specitcation.

This invention has reference to railway-car brakes; and it consists in the improvements hereinafter' described.

In the accompanying drawings, forming part of the specification, Figure 1 is a plan view of a car having my improved brake applied thereto. Fig. 2 is a section on the line x a: of Fig. l. Fig. 3 is a detail view.

A refers to one of the trucks, in whichV are ljournaled, as usual, the axles B, having the car-Wheels, as usual. Beams O are arranged at either side of each axle and are located parallel therewith. .Upon each beam C, near each end thereof, is secured a metal plate, A, which is of the form shown most clearly in Fig. 2, and consists of the upper horizontal portion, a, which bears upon and is secured to the upper side of the beam, and a vertically-depending portion, b, which terminates in a horizontal portion, c. A second plate, A2, is secured to the beams C, on the under side thereof, immediately below the other bar, and said under bar is bent in reverse to the upper bar, so that a portion, c', thereof lies parallel with the portion c. A bolt, d, passes through the portions c c', and said bolt serves as a pivot for a lever, e, between said portions c o', the shorter end of which is opposite the Wheels n, for the attachment of a brake-shoe, while its longer end extends in toward the inwardlyextending end of the other lever, to which it is pivotally attached by means of atie-plate, f.

h, on one of the beams and connected to the inner ends of the adjacent levers.

It will be noted by reference to Fig. 1 that the bearings for the brake-levers are formed by bending the ends of the metal plates A A2, which span the spaces between the pairs of wheels, to the desired shape. This arrangement permits simplicity of the device and enables the beams and their brakes to be properly braced.

The brake arrangement herein described is of simple and durable construction and of general efficiency and certainty of operation.

The combination of the frame having the Wheeled axles journaled therein and the parallel beams C, arranged between the axles, with the plates A A, connecting the said beams and bent to form the projecting arms c c', the levers e, fulerumed between said arms and having the brakeshoes at their outer ends, the linksf, connecting the innerends ot' the levers e, and the operating-cables attached to the said links, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in presence of two witnesses. l
