ABSTRACT:
This invention relates to a coupler shank bearing arrangement for supporting a railroad car coupler on its coupler carrier, and more specifically, to a railroad car coupler support arrangement in which the familiar coupler wear plate that rides on the coupler carrier is replaced by a bearing arrangement of the plane bearing type that provides for essentially wear free support of the coupler on its carrier. The coupler shank lower wall is formed with an elongate mounting slot at the location of application of the conventional wear plate, and extending longitudinally of the coupler shank, to which slot is applied a one piece bearing structure formed from an ultra high molecular weight polymer of dry self lubricating characteristics. The bearing structure is in the form of a one piece body shaped to define a lower generally planar bearing plate portion and an upper mounting portion in the form of an elongate ridge structure especially shaped for bond free but secure application to the coupler shank mounting slot.
