Abstract: A drawbar assembly for interconnecting railcars comprises a drawbar having enlarged ends, each of which is positioned in a socket formed in a railcar sill having outer side walls. A drawbar pin is retained in the sill and passes through an aperture in the enlarged drawbar end, retaining the drawbar in the socket. Pin bearing block means are carried in the drawbar and are in abutting relation with the pin. Slack adjusting wedge means urge the pin against the bearing block means. In accordance with this invention, the slack adjusting wedge means are positioned in the sill outer side walls. Thus, the slack adjusting wedge means can be inspected and maintained without disassembling the drawbar assembly.
