ABSTRACT:
An adapter pad centering device for the side frame of a radially steerable railway car truck with pedestal jaws on opposed end portions thereof for mounting railway car wheel assemblies equipped with a resilient bearing adapter pad mounted between the bearing adapter and the pedestal jaw roof. The adapter pad centering device includes a pair of rigid adapter pad stops on the side frame at opposed sides of the pedestal jaw opening at the roof thereof. Each of the stops has an abutment extending transverse to the side frame. These abutments are spaced so that when the adapter pad is positioned between them, an upper portion of the pad is restrained from significant movement in the longitudinal direction of the side frame. The lower portion of the adapter pad is attached to the bearing adapter and temporarily displaced during steering motions of the truck.
