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 planar support plate equipped with the special liner of Chierici and Murphy U.S. Pat. No. 4,055,254 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 affixing to same along its longitudinal center line a depending flange structure defining a vertical flange of rectilinear configuration and a horizontal flange integral with the vertical flange along the lower edge of the latter and spaced from the support plate. The rigidifying flange structure not only maintains the support plate, and thus the liner surfacing on which the yoke rides in planar relation for achieving maximum benefits of the invention of said patent, but also the support plate itself may be of much thinner gauge than conventionally employed for yoke wear plates. |
