IMPROVED RAILWAY-BRAKE.

Specification forming part of Letters Patent No. 52,820, dated February 27, 1866.

To all whom it may concern:

Be it known that I, E. R. BROWN, of Manch Chunk, in the county of Carbon and State ot' Pennsylvania, havelinvented a new and Im proved Railroad-Brake; and I do hereby declare that the following is a full, clear, and exact description of the same, Which will enable others skilled in the art to make and use the same, reference being had to the accompanyin g drawings, forming part of this specification, in which- Figures] and 2 are plans or top views of car-trucks with my invention applied to them.

This invention has for its object the dis pensing With the brake or shoe bar hitherto universally used, and which is attended with considerable annoyance on account of their liability to break,and which not unfrequently is the source of serious accidents.

rIhe invention consists in attaching the shoes directlyY to levers arranged in such a manner that a brake or shoe bar is rendered entirely unnecessary, and the brake mechanism not only rendered more simple than hitherto, but also less liable to become deranged by use.

A, Fig. 2, represents a car-truck; B B, the axles, provided with Wheels C, as usual.

D D represent levers, which are secured by pivots a, to one end of the truck A, and have arms b pivoted to their outer ends, to which arms the usual shoes E are secured.

The levers D D are connected by rods FX to similar levers F F, which are at the front end or the truck A, and are provided at their outer ends with pivoted arms c, to which shoes G are attached. These levers F F are fitted in guides d, secured to the under side of the truck, and the inner ends of said levers are connected by a link, H, the brake-chain I being attached to the inner end of one of the levers F. By

this arrangement it will be seen that when the chain I is drawn taut b v Winding up the usual brake-shaft J at the end ot' the truck the shoes of the levers D D F F will be pressed against the wheels, the motion being communicated from the levers F F to the levers D D by the rods FX. 0n releasing the brake-shaft J the shoes will free themselves from the Wheels, the levers being so hun g or arranged as to admit of that result.

In Fig. 1 the invention is shown applied to adouble-truck car, but the principle is not changed. In the latter instance the rods FX are divided and attached to the ends of a lever, K, which is secured to the under side oi' the car-bed by a central pivot, e, the outer ends of the rods FX being connected one to the end of a lever, D, at the inner end of the truck, and the other to alever, F, at the opposite end of the truck, as will be fully understood by referring to Fig. l.

Thus it will be seen that by this simple arrangement I am enabled to dispense entirely willi the ordinary brake or shoe bar, and thereby simplify the brake and render it less liable to get out of repair, and avoid accidents Which now frequently occur on account ot' the breaking or casual detachment of the brake or shoe bar.

H avin gthus described my invention, I claim as new and desire to secure by Letters .Patent- As an improvement in railroad-car brakes, the arrangement of the levers D D andlevers vF F, in combination with the rods FX F", to

operate in the manner as herein described.
