A lock member for a Type E railway freight car coupler formed of an as-cast and austempered ductile iron casting, having a slightly over-sized head portion, the as-cast and austempered ductile iron casting having a minimum tensile strength of about 140 ksi, a minimum yield strength of about 110 ksi, a minimum elongation in 2 inches of about 4%, and a BHN of about 321-388.

Slack reduced lock member for a type E raiway coupler

A railway coupler arrangement which eliminates the conventional yoke strap, thereby enabling a larger draft gear to be employed in the coupling without increasing the overall size of the sill. The invention also provides a novel assembly for facilitating a rotary coupler arrangement in which the diameter of the rotary shank can be increased over prior art rotary butt couplers.
