Abstract: A common E/F type draft sill is provided that accommodates either Type E or Type F draft gear components, including rotary coupler applications. The draft sill is preferably cast, but may also be fabricated. The common E/F draft sill is provided with a fixed, integral spring basket of a Type F draft sill to accommodate and house standard spring-biased spring basket support systems and accommodate standard Type F draft gear. Standard vertical connection of Type F draft gear is provided. The common draft sill is also provided with the horizontal keyslot of a Type E draft sill to also accommodate attachment of Type E draft gear. A drop-in E coupler support is also available that replaces the “spring basket” support system used with Type F draft gear so as to allow proper support of Type E draft gear. Additional standardization and reduction of specialized castings can be achieved by incorporating both body bolster pads and body bolster wings on the common draft sill.

Abstract: An extended end-sill assembly for a railcar, which assembly is produced by mating a front-sill casting and back-sill casting having a transition region therebetween wherein the endsill includes a cast-in-place center plate, a support arrangement for a cushioning apparatus and a wide-mouthed end for greater lateral travel of the coupler shank arm, and such dual casting assembly is inapposite to present production of such endsill assemblies that require fabrication of numerous plates, pieces and braces.

Abstract: A draft sill end casting with a locking center pin is disclosed. The draft sill has an open member with an elongate channel aligned with the central aperture of its center plate. A support shelf is within the elongate channel. A center pin has an upper retainer key supported on the shelf, and the center pin extends through the elongate channel to the exterior of the draft sill. The lower end of the center pin has a slot. When mounted on a truck bolster, a lower retainer key is slid through slots in the bolster walls and through the slot in the lower end of the center pin. The two retainer keys, support shelf and bolster walls lock the center pin in position, limiting axial movement of the center pin and limit rotation of the center pin. Thus, the draft sill and truck bolster are locked together to limit relative vertical and horizontal movement between them. The shelf may include rotation stops to limit rotation of the upper retainer once it is in place.

Abstract: An articulated railcar connector assembly includes improved wedge shim and follower block components that are shaped for improved early service life, the wedge shim having laterally spaced vertical lands to contact the assembly end wall and the follower block having a compound curvature bearing surface to receive the end of a male connector member; and both wedge and follower block may have abutting chevron-like concave and convex bearing surfaces wherein the included angle of the convex bearing surfaces exceeds the included angle of the concave bearing surfaces.
