A novel core assembly is used in a sand mold for casting a hollow section in a coupler head extending beyond a horn line into a coupler shank of a coupler for a railway vehicle. The core assembly includes head and shank core members having face surfaces each including a recess surface and a projected surface arranged such that the recess surface in the head core receives the projected surface in the shank core. In a similar way, the recess surface in the shank core receives the projected surface in the head core to maintain the head and shank cores in an aligned abutting relation while supported in the sand mold. The face surfaces extend transversely to the coupler shank along a parting line spaced rearwardly of the plane containing the horn line of the coupler. The face surfaces are further characterized by a conically-shaped projection extending from one core member into a conically-shaped opening in the other core member to mechanically interconnect and align the two core members. The head and shank cores each includes concave side wall sections terminating at the face surfaces to produce cast protrusions in the hollow section of the coupler shank at the parting line between the core members.

In a railway vehicle coupler, the lock includes a leg portion depending from an upper lock body which is solid. The rear part of the upper lock body has a substantially vertical planar surface or stepped planar surfaces across the most rearwardly-extending surface. A beveled and substantially planar rear face or stepped planar rear faces commence at the lower edge of the vertical planar surface and extends downwardly and forwardly to the lock ledge at the guard-arm side of the lock. Above the vertical planar surface, there is a beveled rear surface with or without a step extending downwardly and forwardly from the rear guide at the knuckle side of the lock to the guard-arm side. This surface extends arcuately and commences at the upper edge of the vertical planar surface and extends to the top of the lock.
