ABSTRACT:
A coupler yoke for a coupler of a railway vehicle is constructed with a nose portion which is reinforced by a raised region which surrounds the forward end of the key slot. A tapered buttress extends along the length of both sides of the key slot. The width and depth of the buttress increase from minima at the rearward end of the key slot, and merge with the raised region reinforcing the nose of the yoke.
