ABSTRACT:
A railway car coupler includes a knuckle that is rotatable about a pivot pin. The knuckle is comprised of a tail section, a hub and a nose section. The knuckle is usually made of steel in a casting operation. The pivot pin opening in the knuckle is cylindrical with generally straight walls with a reduced diameter centrally located cylindrical relief area. The nose has a blunt end, and a thicker internal reinforcing section is made by having an end of the face core extend a lesser distance toward the pivot pin opening. The transition area between the tail and the nose is formed by parabolic shaped upper and lower sections.
