Abstract
A knuckle for a railway coupler system is made without internal voids or cores. Instead, external pockets are formed on the front face and tail portion surface to reduce weight. The knuckle is formed by investment casting, which permits a pulling face to be provided without a draft angle or parting line typical of a cast part. As a result of these innovations, the knuckle according to the invention has an improved fatigue life.
