摘要： A railway car coupler head contour gauge (40) includes a cylindrical portion (42) configured to be rotatably coupled to a coupler head (10). A gauging blade (48) is coupled to the cylindrical portion. The gauging blade includes a gauging contour (50) that is configured to align with a contour face of a top pulling lug (28) of the coupler head after operational use of the coupler head.

摘要： A railway car yoke (100) includes a nose end (102) and at least two straps (150) adjoining the nose end (102). At least one top strap (150B) adjoins a top portion of the nose end (102) and at least one bottom strap (150A) adjoins a bottom portion of the nose end (102). The railway car yoke (100) also includes a butt end (101) adjoining the at least two straps (150) such that the nose end (102) and the butt end (101) are separated by the at least two straps (150). The butt end (101) comprises at least one concave contour (110) along an outside surface of the butt end (101). The outside surface is a surface along the butt end (101) opposite the nose end (102) that extends from a top surface of the at least one top strap (150B) to a bottom surface of the at least one bottom strap (150A).

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 railway car coupler head contour gauge (60) includes a cylindrical portion (70) configured to be rotatably coupled to a coupler head. The railway car coupler head contour gauge also includes a pulling lug gauging portion, and a contoured gauging surface (68) that is configured to align with a contour face of a top pulling lug (30) of the coupler head during gauging. The coupler head contour gauge may also include a convex portion (65) configured to align with a buffing shoulder (22) of the coupler head.

摘要： A method for manufacturing a railcar coupler knuckle includes providing a first mold section having internal walls defining at least in part perimeter boundaries of a first coupler knuckle mold cavity. The method includes providing a second mold section having internal walls defining at least in part perimeter boundaries of a second coupler knuckle mold cavity. The second coupler mold cavity of the second mold section is offset from the first coupler mold cavity of the first mold section. The method includes closing the first and second mold sections and at least partially filling the first and second coupler knuckle mold cavities with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle.
