TRACK-BRAKE.

SPECIFICATION forming part of Letters Patent No. 716,616, dated December 23, 1902.

Application tiled June 30, 1902. Serial No'. 113,804. (No model.)

To cir/ZZ whom, 25 may cm2/cern: l

Be it known that we, HERBERT L. BAINES, residing at Manch Chunk, and JOHN EDWARD VAASER, residing at East Manch Chunk, in

the county of Carbon and State of Pennsylvania, citizens of the United States, have invented a new and useful Track- Brake, of which the following is a specification.

The invention relates to improvements in 1o track-brakes.

The object of the present invention is to improve the construction of track-brakes and to provide au exceedingly simple and inexpensive oue of great strength and durability I5 which will be positive and reliable in operation in all weather conditions and which Will be adapted to be operated from either end of a car.

A further object of the invention is to prozo vide a brake of this character Which will be capable of instantaneous application and which will be equally effective with light and heavy loads.

The invention consists in the construction z5 and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side eleva# 3o tion of a track-brake constructed in accordance with this invention. Fig. 2 is a plan View. Fig. 3 is an end elevation of the shoe.

Like numerals of reference designate corresponding parts in all the figures ofthe drawings.

1 designates a brake-shoe having a tapering inner portion presenting a curved upper edge 2 to conform to the configuration of a car-Wheel and provided adjacent to the inner to face of the shoe with a groove 3 to receive the flange of the carwheel when the brake is applied, as illustrated in dotted lines in Fig. 1 of the drawings. The brake-shoe is provided at its inner face with a depending bottom flange 4, arranged to engage the inner face of a rail. By this construction the brake-shoe when applied is firmly interlocked with the Wheel and with the rail and is securely held against lateral displacement. The brake-shoe is also provided at its bottom with a recess in 5o which is secured a steel friction-block 5,Which is adapted to receive the greater portion of the wear and which may be readily replaced when worn. The block 5 is detachablysecured `within the recess by bolts 6, having countersunk heads at the outer face ot' the block and provided at the inner face of the brakeshoe with nuts, as clearly shown in Fig. 3.

The brake-shoes at the opposite sides of a car are connected by a pair of transverse rods 6o 7 and 8 and are supported by links 9 and 10, arranged in pairs adjacent to each brake-shoe and pivoted at their upper ends to brackets ll. Each bracket 1l is provided with an. inclined arm 12 and an upright arm 13, which 65 is secured to the upright portion of an anglebeam 14, and the latter is designed to be con nected with the truck-frame or other portion of the car by any suitable means. The inclined arm 12 is provided with inner and outer 7o portions arranged at an angle to each other, the upper end ot the links being connected With the terminals of the outer portion of the inclined arm.

The downward movementof the brake-shoe is limited by a bar 15, pivoted at its lower or inner end by a suitable fastening device 16 to the brake-shoe and terminating at its upper or outer endin a hook 17, which is adapted to engage the horizontal flange or portion of 8o the beam 14, as illustrated in Fig. 1 of the drawings. The bar 15 is arranged ata slight inclination and is supported by a guide 18, having an opening to receive the bar 15 and composed of a horizontal upper portion and an inclined depending portion. The hook prevents the car-Wheel from riding over the brake-shoe. The upper horizontal portion of the guide 1S is perforated for the reception of bolts 19 for securi-ng the guide to the angle- 9o iron beam, and onebf the transverse rods is connected with a chain 20, which may extend to any suitable operating mechanism for controlling the brake. When the chain is slackened, the brake-shoe will drop by gravity, and an instantaneous application of the brake is thereby obtained, and the greater the load the greater will be the ett'ect of the brake.

The brake is not affected by the weather, and the brake-shoes of a car will lock the same against movement in either direction.

l. In a device of the class described, the

-combination of a brake-shoe, means for suspending the brake-shoe and for permitting the same to swingl upward and downward, a fixed guide and a bar connected with the shoe and slidable in the guide and terminating in a hook arranged to engage the guide to limit the downward movement of the shoe, substantially as described.

2. In a device of the class described, the combination with a support, of a brake-shoe suspended from the support, a guide secured to the support, and a bar connected with the brake-sh0e and arranged in the guide for limiting the movement of the brakeshoe, substantially as described.

3. In a device of the class described, the combination with a support, of a brake-shoe suspended from the support, a guide depending from the support, and a bar pivotaily connected with the brake-shoe and arranged in the guide and terminating in a hook for limiting the movement of the brake-shoe, substantially as described.

4. In a device of the class described, the

combination with a support, of a bracket secured to the support and having a projecting arm, a brake shoe, links suspending the brake-shoe from the arm of the bracket, a guide secured to the support, and a bar connectedwith the brake-shoe and arranged in the guide and provided with means for limiting the movement of the brake-shoe, substantially as described.

5. In a device of the class described, the combination with an angie-iron beam, of a bracket composed of an upright arm secured to one of the flanges of the beam, and an inclined arm extending from the beam, a brakeshoe, links connected with the inclined arm and with the brake-shoe, a guide secured to the angle-iron beam and depending therefrom and having an opening, and a bar pivoted to the brake-shoe and arranged in the opening of the guide and terminating in a hook for engaging the beam,substantia11y as described. In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
