Abstract

An improved method of production of a coupler knuckle, a core assembly for production of a coupler knuckle, and coupler knuckle having an improved interior configuration for handling forces imparted on the knuckle and transferring said imparted forces through the knuckle and improving handling of linear force loads and their transmission. The knuckle interior has a force handling structure that includes spaced apart layers and cavities, with a cavity extending between the nose section and the tail section thereof.
