Abstract
A rotary railway drawbar coupler is provided which comprises two elongated shank members each having a convex butt surface at one end and a generally circular butt surface at the other end. The two elongated shanks are positioned between the two railway cars being coupled such that the circular butt ends are adjacent each other. A connecting collar surrounds the circular flange of which the circular butt surface is a part. Each elongated shank may have a longitudinal cavity extending inwardly from the circular butt surface to accommodate a cylindrical bar that extends between the elongated shanks.
