Abstract: A railway car coupler head contour gauge includes a cylindrical portion configured to be rotatably coupled to a coupler head. A gauging blade is coupled to the cylindrical portion. The gauging blade includes a gauging contour that is configured to align with a contour face of a top pulling lug of the coupler head after operational use of the coupler head.
Abstract: 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 guard arm portion comprises a minimum height less than a height of the shank portion where the guard arm portion meets the shank portion.

Abstract: A method for manufacturing a railcar coupler knuckle includes providing a cope mold portion and a drag mold portion. The cope and drag mold portions have internal walls defining at least in part perimeter boundaries of a coupler knuckle mold cavity. The method includes positioning one or two internal cores within either the cope mold portion or the drag mold portion. The one or two internal cores are configured to define a kidney cavity, a finger cavity and a pivot pin cavity of a coupler knuckle. The method includes closing the cope and drag mold portions with the one or two internal cores therebetween and at least partially filling the mold cavity with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle.
