In a railway coupler connection, an improved slackless connection in which an arcuate conical surface is provided about the butt end of a vertically restrained coupler member which is seated within the pocket of a self-adjusting follower member having a corresponding arcuate conical surface about a pocket therein. The corresponding arcuate conical surfaces interface in mated alignment in order to permit horizontal angling of the coupler member while restraining the butt end of the coupler member in a lateral and longitudinal position within the center sill. As in-service wear occurs, the self-adjusting follower member will drop with respect to the coupler member to maintain this zero-slack arrangement. The coupler member may be placed in the upper portion of the center sill permitting a lower center sill height while staying within the coupler height range specified by the American Association of Railroads.
