Abstract: A railcar operating shaft assembly including an operating shaft having first and second ends with a capstan provided at each end of the operating shaft. Each capstan defines an axis about which the capstan rotates and has first and second axially aligned end portions. One end portion of each capstan is releasably connectable to one end of the operating shaft. The second end portion of each capstan defines a socket opening to a terminal end of the second end portion of the capstan. The socket defined at the free end of the second end portion of the capstan is axially aligned with the longitudinal axis of the capstan. An insert is configured for non-rotatable accommodation within the socket defined at the second end portion of each capstan. The insert defines a bore axially aligned with the longitudinal axis of the capstan and has a closed and non-circular marginal edge extending axially inward from the terminal end at the second end portion of the capstan.

Abstract: A bar lock assembly including an elongated operating shaft and a pair of bracket assemblies for securing the operating shaft to a generally flat panel. Cam structure is adapted to be secured to each end of the operating shaft. Each bracket assembly includes a series of components including bearing structure disposed about and intermediate the first and second ends of the shaft and a mounting bracket configured for operable association with the bearing structure to allow for free rotation of shaft about a fixed axis. A coupling maintains the components of the bracket assembly together as a preassembled unit. A method for assembling such a bar lock assembly to a panel is also disclosed.
