ABSTRACT:
A car impact shock absorbing and coupler centering device for use in connection with railroad track bumping posts, which device comprises a block shaped body formed of resiliently compressible material that is of parallelepiped configuration which is adapted to be mounted against a fixed abutment defined by the post at the level of the center line of draft. The resilient body extends transversely of the track and is formed with a longitudinal bore through which extends a leaf spring assembly that has its ends projecting to either side of the body and which is proportioned transversely of the body bore to engage the body bore upper and lower sides. The ends of the leaf spring assembly are each equipped with a follower plate structure between which and a fixed support on the bumping post a compression spring assembly is interposed. Carried by the leaf spring assembly is a centering device for centering the car coupler relative to the resilient body. Car impacts against the shock absorbing device are resisted by the resilient body and leaf spring resiliently deflecting in combination.
