Abstract
An "E" type coupler for a railway car has a key connecting the coupler shank to an end-of-car cushioning unit. The cushioning unit has a slidable end cap housing assembly receiving the coupler shank and a slot extending through the shank and one side of that housing assembly to receive and mount the coupler key. An inner recess in the other opposed side of the housing assembly recess receives the key in abutting relation to such other side and a retainer on the other side contacts and retains the key in the housing assembly.
