摘要： Center filler plates for mounting on draft sills of railway car underframes are disclosed. The center filler plates have four pockets surrounding a hub. The pockets are shallower than in the prior art, and the walls defining the pockets meet in radii having larger radii of curvature than in the prior art. The shallower pockets and larger radii of curvature facilitate removal of the casting from the molding sand in the cope and drag sections of the mold. The formation of burned-in sand is limited in the present invention, and any burned-in sand that does form is also more easily removed from the center filler plates of the present invention. The base portion of the center filler plates is not as high as in the prior art. The ribs of the center filler plate and the walls of the hub are thicker than in the prior art to provide the needed strength to the center filler plates. In one embodiment, the ribs taper toward the hub, and the hub is shorter than the surrounding web; a tool may be inserted through the kingpin hole, expanded to bear against the tapered surfaces of the ribs; a machine may be used to lift the center filler plate and move it into position on the draft sill. The tool may then be contracted and removed, and the center filler plate may be secured to the draft sill through welding or other techniques.

摘要翻译： 公开了用于安装在铁路车底架的底板上的中心填充板。 中心填充板具有围绕轮毂的四个口袋。 口袋比现有技术浅，并且限定袋的壁与半透镜相比，其比现有技术具有更大的曲率半径。 较浅的口袋和更大的曲率半径有助于从铸模的上模和拖曳部分的型砂中移除铸件。 在本发明中，烧成砂的形成是有限的，并且任何形成的烧成砂也可以更容易地从本发明的中心填料板上除去。 中心填充板的基部不像现有技术那样高。 中心填充板的肋和轮毂的壁比现有技术更厚，以向中心填充板提供所需的强度。 在一个实施例中，肋朝向毂逐渐变细，并且轮毂比围绕的腹板更短; 工具可以穿过主销孔插入，膨胀以抵靠肋的锥形表面; 可以使用机器来提升中心填充板并将其移动到起草条上的适当位置。 然后可以将工具收缩和移除，并且中心填充板可以通过焊接或其它技术固定到通风门。

摘要： The present invention provides a lightweight draft sill end casting for use with railroad cars. The cast draft sill has side walls, front and rear stops, front and rear rib sets and a center plate that are cast as a unit. The draft sill has an open area between the tops of the side walls between the front and rear stops, with a cast metal span connecting the two side walls. The cast metal span may comprise one or more spacer bars or part of a top wall. The cast metal span is in the area between the planes of the front stops and the rear stops. The front and rear stops are spaced below the tops of the side walls. In one embodiment, there are additional lightener holes in each side wall between the ribs in the rear rib set and in the pocket. The total weight of the cast draft sill is not substantially greater than the weight of a comparable fabricated draft sill of substantially the same size, and has a greater fatigue life. The total open area connecting the interior and the exterior of the draft sill between the front stop plane and the rear stop plane is at least 130 square inches.

摘要： A brake beam wear plate assembly for a railway car truck sideframe is provided. A brake beam wear plate is provided and adapted to be inserted in a brake beam guide which is typically an integral component of a railway car truck sideframe. The brake beam wear plate itself is comprised of a channel shaped body having an upper wall, a lower wall, and a bottom wall. The brake beam wear plate is typically comprised of a polymer or a high density plastic. The brake beam wear plate also includes a projecting locating tab and the brake beam guide itself includes a complimentary cutout section.

摘要： The present invention provides a lightweight draft sill end casting for use with railroad cars. Weight reductions are achieved and adequate strength is maintained by using a set of front ribs and back ribs, with angled top and bottom ribs. The back rib set has a single central rib along the central plane of the draft sill. A single horizontal center plate rib is also used in the area of the center plate. The side ribs at the center plate have larger lightener holes. Holes are also provided in the bottom wall of the casting. Larger lightener holes are provided in the area of the draft sill pocket. These holes are moved upwardly to lower the center of gravity of the draft sill. The draft stops may be spaced from the top wall of the draft sill and from the bottoms of the side walls.
