Abstract
A railway vehicle drawbar slackless rotary dump arrangement having one end fixed against rotation to one railway vehicle and the other end connected to be rotatable in a second adjoining railway vehicle. Slack elimination is provided by a wedge at each connection. The rotatable connection includes a drawbar ball end held between concentric pulling blocks and follower block with a shim and cradle arrangement to maintain alignment of the concentric parts. Appurtenances are provided to the drawbar shank to simulate striker castings and interlocked E and F type couplers so as to accommodate the drawbar for use with indexing apparatus at the unloading site. Means are also incorporated to move cars in case of failure of system components.
