ABSTRACT:
A drawbar for a slackless drawbar system comprises an elongated bar having a load support portion adjacent its one end for connection to one of a pair of adjacent cars in a train, a pin receiving opening extending through the load support portion, a hemispherical recess extending partially around the pin receiving opening and a pin bearing having a hemispherical outer surface receivable in the hemispherical recess and a cylindrical inner surface to receive a pin. The pin bearing preferably is constructed of two symmetrical halves retained in the hemispherical recess by a retaining clip of spring material and the pin receiving opening is provided with a recess to receive the pin bearing retaining clip. The drawbar is provided with a second load support portion at its other end which may be the same as the load support portion at its one end or which may be different if required to connect to a railway car with a different form of coupling.
