CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 318,419, dated May 19, 1885.

Application tiled April 7, 1885.

lo all whom it may concern:

Beit known that we, PAUL H. CURTNER and CHARLES C. GENUNG, citizens of the United States, residing, respectively, at Hazleton, Gibson county, and Evansville, in the county of Vanderburg, and State of Indiana, have invented Certain new and useful Improvements in Gar-Brakes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to car-brakes, and is an improvement upon the carbrake for which Letters Patent No. 313,186 were granted us March 3, 1885, and has for its obj ects to equal ize the leverage and more easily and readily apply power to the brakes by the means of additional levers and chains and their different connections, and to more certainly and securely keep the respective parts in place. These objects are attained by the mechanism illustrated and operated by the brakeman.

in the drawings forming a part of this speci ication, in Which- Figure l :is a sectional view. Fig. 2 is aview of brakerod detached from the car. Fig. 3 is a detached view, taken from the top, of a clamp to be attached to one side of the car. Fig. 4 is a detached side view of a guide for one end ofthe bar B. Fig. 5 is a detached view of the bar B, and shows one edge thereof. Fig. 6 embraces detached views of the bar B, connecting-rods C D, pivoted bars I J, connecting chain K, and hook K. Fig. 7 is a view taken from the bottom of the car on the under side, and shows a part of the car and also the several parts illustrated in Fig.'6 connected with each other and in their relative positions. Fig. 8 is a Side elevation of a part of a car.

The letterAindicates the brake-rod, the upper portion of which is curved over the top of the car, in order to be more easily grasped This rod passes through a clamp, G, secured to one side of the car, and provided with projecting teeth and a spring, H, by means of which the rod is held in the position where placed by the brakeman, and is also provided with slots A A. The lower slot, A, fits over the end of a stud or bolt, F, attached to the side of the car, and which forms the pivot or fulcrum upon which the rod A oscillates when operated by The elongated form of the the brakeman.

the brake is not in operation, and prevents 6o t-he shoe from pressing against the ear-wheel.

The lower end of the rod Ais providedwith a screw-thread, and passes through a Slot, BW', in the outer end of the bar B, to which it is secured by the nut b.

An angle-plate of metal, E, having a slot, E', as shown in Fig. 4, is secured to one of the sills of the car. The slot therein, E', is for the passage of the bar B, which it supports, and at the same time permits to slide freely back and forth in a horizontal direction when acted upon by the brake-rod A. The bar B is pivoted by a bolt, B', to a cross-piece, L, secured to the bottom timbers of the car. This bar has openings B and B near each end, which are intended for the passage of suitable bolts, by means of which two connecting-bars, C D, having bifurcated ends C D', are secured thereto. The other ends of these bars (indicated by the letters C 13) are attached to the bars I J by bolts j, which pass through suitable openings therein for this purpose. The bars I J are secured to the bottom of the car by means of bolts I J which also serve the purpose of fulcrums or pivots, upon which these bars oscillate. The inner ends of the bars I J are connected to each other by a chain or chains, K, provided with a hook, K', which engages with brake-beam rods S U, the other ends of which are secured to the brakebeams T, having shoes V, which may be of any. of the ordinary forms in general use.

It will be observed that any movement of the brake-rod A in a backward or forward direction will be communicated to the bar B, thence through the connecting-bars C D to the bars I J, then by the chainK and hook Kto the brake-beam rods S U, brakebeams T, andshoes V, and thus cause the shoes V to bear against the wheels of the car or to be withdrawn therefrom.

Having described our invention, what we IOO desire to secure by Letters Latent, and claim, I Chains K, adapted to engage with brakeisbeam rods S U, whereby the brake-beams T In a railroad-car brake, the combination of and shoes V may be caused to bear against or I5 brake-rod A, curved over the roof of the ear, be removed from the ear-Wheels, substantially 5 having slots AA, the clamp G, having spring as described, and for the purposes set forth.
