CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 554,593, dated February 11, 1896.

Application niet october 19, 1895.

To all whom t may concern:

Be it known that I, FERDINAND GABLER, of Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Improvement in Oar-Brakes, of which th'e following is a specification.

The object of my invention is to provide a simple and effective car-brake.

It relates to that form of car-brake, heretofore patented by me January 24, 1893, No. 490,554, in which the brake-shoes are projected to contact against the wheels by the straightening of a pair of toggle-arms located between the two shoes operating against, adjacent wheels; and it consists in features of improvement which I will now proceed to describe with reference to the drawings, in which- Figure lis an inverted plan view of a cartruck provided with my improved brake. Fig. 2 is a sectional end view; Fig. 3, a secmodiiication.

In the drawings, A A are two brake-shoes adapted to operate against the adjacent peripheries of the two wheels of a truck on the same side of the car. These shoes are'suspended by hangers a a, and have a loose jointed connection with two horizontal togglearms B B, which are jointed together at a middle point b, and at the same point are jointed by the same bolt or pintle-pin to a stem C extending transversely toward the middle of the car. The inner ends of these two stems on opposite sides of the car are attached to a chain or flexible connection E. This chain passes around two pulleys F F fixed upon a stationary axis to the cross-timber of the car with a housing G2, and also around an intermediate pulley G, carried by a clevis H, which (see Fig. 3) is jointed to the lower end of the brake-lever J, fulcrumed upon a stationary support I and connected at its upper end to the brake chain and rod K, through which the brakes are applied.

lVhenever power is applied through the brake-chain to put on the brakes it deflects lever J, and, by pulling clevis H and pulley Serial No. 566,196. (No model.)

brake-shoes at a point directly between thesame.

The above construction affords a simple, powerful, and easily-operated car-brake, in which the power is equally distributed to the brake-shoes on opposite sides of the car, the pulleys F F and G and chain E forming an equalizing attachment that insures an even application of the power to the two sets of brake-shoes, thus causing an even braking of the wheels on opposite sides of the car.

As a modication of the equalizing attachment, I may, as in Fig. 4, use two chains E Epassing around pulleys FF and connected to the opposite ends of a lever or singletree G fulcrumed in the middle to the clevis H to accomplish the same result.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

A car-brake comprising two sets of brakeshoes, two toggle-arms on each side of the car connected at their outer ends to the two adjacent brake shoes and jointed to each other in the middle, a spiral spring arranged betweenv the'brake-shoes of each pair and connected to the same, two transverse stems also connected to the middle joints of the toggles, and an equalizing device connected to the inner ends of the transverse stems and also to the brake-applying mechanism substantially as and for the purpose described.
