Abstract: A disc brake assembly for a railway truck is provided. The truck includes at least two wheel axle sets and brake discs mounted to the wheel axle sets. Extending between the wheel axle sets is a longitudinally extending truck frame. Also extending between the wheel axle sets and supporting the truck frame via primary springs are equalizer beams that further extend beyond the wheel sets and through an opening in the truck frame. Disc brake calipers are mounted to the equalizer beams with the caliper engaging the brake discs of the wheel sets. The assembly results in the brake discs and calipers being unsprung. In other words, the brake discs and calipers do not move relative to each other.

Abstract: A railway vehicle truck assembly comprises the following, in part: wheel sets having longitudinally spaced, transversely extending axles, and wheels mounted to the axles; transversely spaced longitudinally extending side frames mounted to the axles; and a transversely extending bolster mounted to the side frames. The bolster has a center bowl and opposed, elongated bolster arms extending from the center bowl. The bolster arms each form spaced structural walls, a first of the structural walls of the bolster arms having a bolster anchor fitting defined thereon, and a second of the structural walls having a bolster anchor opening defined therethrough. The structural walls further define an inner cavity between the walls, and bolster anchors connect the side frames to the bolster. The bolster anchors are located transversely between the side frames, further extend to the fittings, and extend at least in part through the inner cavity of the bolster and the bolster anchor openings to brackets on the side frames.

Abstract: A lightweight and topless draft arm is disclosed for use in a railway car. The draft arm includes an open top surface with the metal layer removed, lateral support members and tiebars transversing the side walls for greater draft arm strength, and thinner side walls below the keyslots. Removal of the top surface of the draft arm eliminates the traditional double layer of material formed by the bottom of the car body and the top of the draft arm. Effectively, the bottom of the car body becomes the top of the draft arm resulting in a lighter weight railway car.

Abstract: A railway Type H tightlock coupler locklift assembly for coupling railway cars comprises a Type H rotary locklift toggle, a Type H rotary locklift lever, and a rivet connecting the rotary locklift toggle to the rotary locklift lever. The Type H rotary locklift lever further comprises a standard flange or finger for operatively engaging a coupler operating rod and a second opposing flange or finger that abuts the coupler operating rod. The second opposing flange or finger prevents unintentional rotary motion of the rotary locklift lever by acting on or abutting against the locked operating rod, thereby preventing unintentional uncoupling of the railway cars when coupler components of such cars are struck by flying debris.

Abstract: A drawbar assembly for interconnecting railcars comprises a drawbar having enlarged ends, each of which is positioned in a socket formed in a railcar sill having outer side walls. A drawbar pin is retained in the sill and passes through an aperture in the enlarged drawbar end, retaining the drawbar in the socket. Pin bearing block means are carried in the drawbar and are in abutting relation with the pin. Slack adjusting wedge means urge the pin against the bearing block means. In accordance with this invention, the slack adjusting wedge means are positioned in the sill outer side walls. Thus, the slack adjusting wedge means can be inspected and maintained without disassembling the drawbar assembly.
