  • Patent number: 3938629
    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.
