Abstract

An improvement in dead lever lugs for mounting on cast metal bolsters for railway trucks is disclosed. The bolster has two side walls. The side walls have angled portions that meet in radii along the junctures of the angled portions, The dead lever lug has two arms joined by a bridge section. Each of the arms has a mounting surface that is shaped to mate with the shape of one of the angled surfaces of the bolster. The mounting surfaces of the dead lever lug arms are separated by a gap. When the dead lever lug is mounted on the bolster, the dead lever lug straddles the juncture of the angled portions of the side wall. One mounting surface of each arm is positioned against one of the angled portions of the side wall and the gap overlies the juncture of the two angled portions of the side wall. With the dead lever lug of the present invention, no flat raised mounting area is needed on the side wall of the bolster.
