Abstract
A railway car coupler knuckle includes integral nose, hub, and tail portions. The tail portion has a lock shelf and an associated locking face as well as pulling lugs associated therewith. A tail core support aperture in the tail portion communicates with internal tail portion coring extending from a free end of the tail portion toward coring in the hub portion. The core support aperture and tail portion coring have been strategically relocated and reconfigured to reduce stresses imposed at critical areas during loading of the knuckle pulling lugs and locking face to thereby increase the resistance of the tail portion to fatigue failures.
