Abstract
A rigidifying arrangement for self lubricating wear plate assemblies employed for supporting the inner end of the vertical yoke used in railroad car coupler draft gear rigging, in which the wear plate is in the form of a support plate of channel shaped transverse cross section configuration having a planar web portion equipped with a special polymeric liner for supporting the yoke inner end at its operative level within the car center sill. The support plate is rigidified to maintain its planar configuration under the weight of the draft gear and yoke acting on it, by forming same to be of the indicated channel shaped configuration defining along either side edge of the plate web portion a depending flange, in which the flanges are proportioned relative to the plate web portion to provide a yoke support plate of one piece construction that is three times as strong as the conventional draft gear wear plate while being only approximately one third the weight of same.
