摘要： A cast metal sideframe for use in a railway car truck has a spring seat for supporting the springs of a spring set. The sideframe is molded using a core that includes a portion for defining the exterior surface of the spring seat. The core can be a single piece or multi-piece core. The spring seat includes a plurality of aerodynamically-shaped spring retainers formed on the top face spring seat. The aerodynamic shape of the spring retainers reduces the tendency for sand to swirl and create voids during formation of the sand core that is used to mold the sideframe. The aerodynamic shape may include forming at least some of the side walls of the spring retainers at an obtuse angle with the top face of the spring seat. The spring retainers may have concave top faces so as to reduce the volume of material comprising the spring retainers. Reducing material volume is beneficial for reducing shrinkage during cooling of the sideframe, thereby reducing the tendency for separation, tears and cracks to form on the top surface of the spring retainer.
摘要翻译： 用于铁路车辆的铸造金属侧架具有用于支撑弹簧组的弹簧的弹簧座。 侧框使用包括用于限定弹簧座的外表面的部分的芯来模制。 核心可以是单件或多件式核心。 弹簧座包括形成在顶面弹簧座上的多个空气动力学形状的弹簧保持器。 弹簧保持器的空气动力学形状减少了在形成用于模制侧架的砂芯的形成期间沙子旋转并产生空隙的趋势。 空气动力学形状可以包括以与弹簧座的顶面成钝角形成弹簧保持器的至少一些侧壁。 弹簧保持器可以具有凹的顶面，以便减小包括弹簧保持器的材料的体积。 降低材料体积有利于减少侧架冷却期间的收缩，从而减少在弹簧保持器的顶表面上形成的分离，撕裂和裂纹的趋势。

摘要： The number of cores used in casting bolsters and sideframes is reduced. End cores and a center core are placed in a mold with cope and drag portions. Each core includes integrally-formed portions for defining portions of the interior surfaces of the bolster or sideframes. The integrally-formed portions may include a portion for defining the side window of the sideframe formed integrally with other portions, and may include a pedestal portion formed integrally with other portions. The integrally-formed portions may contact both the cope and drag portions of the mold. The end cores may include integrally formed core prints for supporting the core in the mold. The integrally-formed portions of the center core include connections that are formed integrally with the other portions. Molten metal is introduced into the mold to cast the bolster or sideframe.

摘要： Improvements in the method of making cast metal bolsters for railway trucks are disclosed. The bolster is cast in a mold using a one-piece center core. The center core has a first end inboard of the first outboard end of the mold and a second end inboard of the second outboard end of the mold. The one-piece center core extends from the first end across the center area of the mold to the second end. It has surfaces to define interior surfaces of the bolster top wall, bottom wall and side walls on both sides of the bolster central transverse plane and bolster central longitudinal plane. Two one-piece end cores are also used. Each one-piece end core has surfaces shaped to define the interior surfaces of the bolster top wall, bottom wall and side walls from a position inboard of one friction shoe pocket to the first outboard end of the bolster. Each has surfaces to define interior surfaces of the bolster top wall and bottom wall on both sides of the bolster central longitudinal plane and interior surfaces of the bolster side walls on both sides of the perpendicular bolster longitudinal plane.
摘要翻译： 公开了制造铁路货车铸铁垫块的方法的改进。 使用一体式中心芯将支柱铸造在模具中。 中心芯具有位于模具的第一外侧端部的第一端和模具的第二外侧端部的第二端。 一体式中心芯从第一端延伸穿过模具的中心区域到第二端。 它具有表面，用于限定枕骨中心横向平面两侧的枕头顶壁，底壁和侧壁的内表面，并支撑中心纵向平面。 还使用两个一体式端芯。 每个单件端芯具有成形形状的表面，其形成为从一个摩擦瓦口袋内的位置到垫片的第一外侧端部的顶板壁，底壁和侧壁的内表面。 每个都具有表面，以限定在枕形中心纵向平面的两侧的枕头顶壁和底壁的内表面以及在垂直支撑纵向平面两侧的垫板侧壁的内表面。

摘要： An improvement in cast metal bolsters for railway trucks is disclosed. The bolster has a top wall, a bottom wall and sidewalls. All of the walls have interior and exterior surfaces. Two transverse ribs extend between the top wall and bottom wall and two spaced longitudinal ribs extend from the top wall to the bottom wall. The bolster has a top portion, a bottom portion, a central vertical longitudinal plane between the sidewalls and a perpendicular vertical transverse plane. The transverse ribs have opposite faces in the top portion and in the bottom portion. A vertical plane extends between the opposite faces of the transverse ribs in the top portion and in the bottom portion. The opposite faces of the transverse ribs in the top portion do not diverge from a vertical plane in the same direction and opposite faces in the bottom portion that do not diverge from a vertical plane in the same direction. The transverse ribs may have a vertical plane of symmetry. The bolster is made from improved cores, including a one-piece center core that has surfaces for defining the interior surfaces of the top wall, bottom wall and side walls. The bolster may have several ribs all of this configuration. By having ribs as described, the one-piece center core can be made and pulled from the core box without damage. Other improvements to bolsters, sideframes, and to cores and methods for making bolsters and sideframes are also disclosed.

摘要： Improvements in cast metal sideframes and bolsters for railway trucks are disclosed, along with improvements in the processes of casting such products and the cores used in the casting process. In one aspect, the cores are consolidated to provide two one-piece end cores, a one-piece center core, and a bottom center core for the sideframe and two one-piece end cores and a center core for the bolster. The consolidated cores may include cores to define various bolt holes. In another aspect, various cores may be made with step joints for interlocking support without weight-supporting chaplets. In another aspect, a locator boss may be formed on one or more of the cores for proper positioning of the core on the drag mold. Other improvements disclosed include providing a radial draft on the casting surrounding a bolt hole at a core parting or joint line so that nuts and washers may be evenly loaded. In the bolster interior, ribs may be straightened. In another aspect, core prints are used to support the cores on the drag mold surface. The core prints are connected to the core body through necks or bridges that define holes in the cast metal piece. The juncture of the core print and drag mold are spaced from a perimeter of the neck so that any metal fin formed at this juncture is on the exterior of the casting.

摘要： The number of cores used in casting sideframes is reduced. A pair of end cores and a center core are placed in a mold with cope and drag portions. Each core includes integrally-formed portions for defining portions of the interior surfaces of the sideframes. The integrally-formed portions may include a portion for defining the side window of the sideframe formed integrally with other portions, and may include a pedestal portion formed integrally with other portions. The integrally-formed portions may contact both the cope and drag portions of the mold. The end cores may include integrally formed core prints for supporting the core in the mold. The integrally-formed portions of the center core include connections that are formed integrally with the other portions. Molten metal is introduced into the mold to cast the sideframe.

摘要： An improvement in dead lever lugs for mounting on cast metal bolsters for railway trucks is disclosed. The bolster has two side walls. The side walls have angled portions that meet in radii along the junctures of the angled portions. The dead lever lug has two arms joined by a bridge section. Each of the arms has a mounting surface that is shaped to mate with the shape of one of the angled surfaces of the bolster. The mounting surfaces of the dead lever lug arms are separated by a gap. When the dead lever lug is mounted on the bolster, the dead lever lug straddles the juncture of the angled portions of the side wall. One mounting surface of each arm is positioned against one of the angled portions of the side wall and the gap overlies the juncture of the two angled portions of the side wall. With the dead lever lug of the present invention, no flat raised mounting area is needed on the side wall of the bolster.

摘要： Improvements in cast metal sideframes for railway trucks are disclosed, along with improvements in the processes of casting such products and the cores used in the casting process. A radial draft is provided on the casting surrounding a bolt hole at a core parting or joint line so that nuts and washers may be evenly loaded. The radial draft is formed on the sideframe column, on the side opposite the side to which a wear plate is mounted. The bolts for mounting the wear plate extend through the bolt hole, and the nuts and washers connected to the bolts bear against the tapered radial draft surface.
