IMPRCVEMENT IN CAR-BRAKE PADS.

Specification forming part of Letters Patent No. 1S [,482, dated August 22, 1876 application filed To all whom it may concern Be it known that we, THOMAS RUSSELL and JOHN F. SHANK, of Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented -certain new and useful Imconstruction and arrangement of a brake-pad to be fastened on the springboard of a cartruok for attaching the brake-han gers or brakeclevises, as will be hereinafter more fully set forth.

The accompanying drawing fully illustrates our invention. A A represent the two pads, which consist each of an upright bar formed With two perforated ears, a a, at its upper end, and with an outwardly-projectin g flan ge, b, along the lower end. The pad is also provided with a slot, d, in the form vof an inverted T. In connection with these pads'we use a bar, B, havingaslot, e, cut on each side near 'each end, or in other words, forming a T on each Aend of the bar. In attaching these pads to the spring-board G of a car-truck, the bar B is laid on top of the board, and a pad, A, placed on each end thereof by letting the slot d in the pad pass over the end of the bar, and then pressing March 21, 1876.

in the pad. The parts are so proportioned` that when thus placed the pads stand in a vertical position close up to and against the sides of the spring-board. An iron strap, D, is then fastened to each side of the springboard by suitable screws passing horizontally A across the pad immediatelyabove and against the ilange b, and at the front edge of the pad said strap extends downward and under the spring-board, and is further secured on said under side thereof. By this construction the pad can be attached to the springboard without taking the wheels out of the truck, or taking the truck apart.

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

A brake-pad consisting of the two uprights A A, formed with ears a, flanges b, and T- shaped slots d, and the cross-bar B, having T-shaped ends, in combination with strapirons D, or their equivalent, for holding them to the spring-board, substantially as'herein set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 14th day of March, 1876.
