Abstract

A railway track brake comprising a series of segments connected together in pairs and installed transversely between the rails of the track, each segment including a top beam with a shaft rotatably installed inside the top beam and provided at its ends with projecting arms carrying contact rollers for engagement with the wheels of the vehicle to be braked. The top beam is rotated with the shaft when the vehicle wheels contact the rollers and rotate the arms. The top beam is connected to a bottom beam which is linearly displaceable by means of a crank and a connecting rod. The bottom beam is connected to an energy absorbing device including a strip having a friction lining in contact with rotatable rolls. The bottom beams of each pair of segments are interconnected by a double-arm lever such that the bottom beams move in opposite directions.

Dependent claims

A railway track brake comprising a plurality of pairs of brake segments disposed transversely between rails for braking the wheels of a vehicle traveling on the rails, each segment comprising a rotatable top beam, a shaft rotatably supported by said top beam and having ends with projecting arms, contact means on said arms for being contacted by the wheels of the vehicle to be braked to cause rotation of said arms, means for producing rotation of said top beam in accordance with rotation of said arms, a displaceable bottom beam, means guidably supporting the bottom beam for linear displacement, a crank secured for rotation with said top beam, a connecting rod pivotably connected to said crank and to said bottom beam to displace the latter upon rotation of said crank, energy absorber means coupled to said bottom beam for resisting displacement thereof, and a double arm lever having ends pivotably interconnecting the bottom beams of each pair of brake segments so that said bottom beams move in opposite directions.
