Abstract
A clamp for securing a railroad car in a rotary car dumper includes a guide pipe member mounted adjacent the section of track carried by the rotatable dumper frame, a clamp pipe member telescopically mated with the guide pipe member and a clamping jaw member extending laterally from the free end of the clamp pipe member toward the track section. Releasable coupling means in the form of a longitudinal slot in one pipe member which is engaged by a radially extending guide bar member tack welded or bolted to, or inserted in a slot in, the other pipe member permits the clamp pipe member to be extended and retracted relative to the guide pipe member by a coaxially mounted hydraulic cylinder while resisting rotational movement therebetween. If excessive torque is applied to the clamp pipe member, such as when the clamping jaw member is struck by a moving car, the guide bar member is sheared and the clamping pipe member rotates to swing the clamping jaw member out of the path of the car.
