Abstract
A railway coupler connection is provided for slackless arrangements wherein spacer lugs are provided between the coupler shank and the sill side castings to restrain lateral movement of the coupler member at about the draw key; and access ports are provided in a pocket casting to facilitate withdrawal of a wedge holding the coupler parts together whereby the parts may be disassembled.

In a slackless coupler connection for a railway car wherein a coupler member extends into a railcar center sill and a convex end of said coupler member abuts a concave follower block held against a wedge within said sill and a draft key extends horizontally through a slot in the coupler member shank and through slots in a pair of sill side castings secured to the center sill, the improvement comprising:
- spacer means on at least one of said pair of sill side castings and said coupler member to hold said coupler member evenly between said sill side castings, said spacer means and the other of said pair of sill side castings and said coupler member not provided with spacer means having confronting surfaces which surfaces are congruently curved whereby the coupler member may be vertically and laterally angled and may roll with respect to said sill side castings and the center sill.
An improved coupler member for a railway car said coupler having a shank with a draft key slot for installation in the center sill of a railway car, the improvement comprising:
- curved surfaces that are convex and of generally spherical portions which curved surfaces are positioned on opposite sides of said shank in areas adjacent the key slot therein.
In a slackless coupler connection for a railway car wherein a coupler member extends into a railcar center sill and a convex end of said coupler member abuts a concave follower block held against a wedge within said sill and a draft key extends horizontally through a slot in the coupler member shank and through slots in a pair of sill side castings secured to the center sill, the improvement comprising:
- spacer means on at least one of said pair of sill side castings and said coupler member to hold said coupler member evenly between said sill side castings, a pocket within said sill to retain said wedge against said follower block, said pocket casting including ports in the top thereof, and lifting lugs on said wedge aligned with said ports whereby said wedge may be engaged and withdrawn from between said pocket casting and said follower block.
