摘要： A railcar coupler includes a coupler head portion extending from a shank portion. The coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler head portion comprises a nose portion and a gathering face extending from the nose portion for engaging a second coupler knuckle coupled to the second railcar coupler. The coupler head portion comprises a guard arm portion extending from the nose portion towards the shank portion. The coupler head portion comprises a horn portion having a back surface. A distance between the back surface of the horn portion and a nose end of the guard arm portion is less than 11 inches. The coupler head portion comprises a locklifter shelf less than 2 inches above a bottom edge of the coupler.

摘要： A method for manufacturing a railcar coupler knuckle includes, before casting, positioning an external chill within a cope mold portion and a drag mold portion offset from and adjacent internal walls of a pulling face and a throat of the cope and drag mold portions, thus producing a casting with reduced micro-shrinkage in at least the throat, a high-stress section of the casting. Use of subsurface chills produces an improved surface with fewer inclusions when compared to an equivalent surface produced in a process without use of a subsurface chill. The external chill may be a cone chill of a larger size to improve cooling and solidification at and below the surface. The external chill may also be a cylindrical and/or oblong chill with a tapered design that may correspond to the internal walls of the cope and drag mold portions between the pulling face and the throat.

摘要： A railcar coupler having a head portion extending from a shank portion, the coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler has weight reduction features that also are configured to provide strength to the coupler when handling forceloads. The coupler may have a head with a front face with bores provided in the front face a cavity extending through the coupler, a guard arm with cavities formed therein, and a shank having a plurality of longitudinal cavities and adjacent ribs separating the cavities. Preferred embodiments may be constructed from an austempered metal.

摘要： A core assembly for creating interior spaces in a railcar coupler knuckle is designed to be set in a cavity with cope and drag sections. The cavity is shaped to form a railcar coupler knuckle and includes a first wall that forms the substantially vertical outside wall of the tail of the knuckle. The core includes a kidney section with a rear core support section that extends at least 0.5″ outside the first wall of the cavity when the core is set in the drag.
