  • Patent number: 4085831
    Abstract: A rod guard adapted to be attached to a brake beam member to prevent a disconnected or broken brake rod from falling from a railway car. The guard consists of a looped hanger and a clamp having the general configuration of the brake beam member to which the rod guard is to be applied. A lower loop of the hanger encircles the brake rod. An upper loop of the hanger extends through a slot in the clamp exposed forwardly of the front surfaces of the brake beam member and is secured to the clamp by a reversely bent central tab forced over the upper horizontally extending end of the hanger such as by a hammer. The clamp is secured to the brake beam by a pair of horizontally spaced end tabs between which the upper end of the hanger is received and held by the end tabs against spreading. The end tabs are forced over the brake beam member by a hammer or the like in a direction opposite to the center tab to secure the guard to the brake beam.
