摘要： A resilient pad having a base with two side arms and two side lips for resiliently holding the base on a pedestal wear plate, the pad being configured with dome shaped portions disposed substantially perpendicular to the direction of the pad and being spaced apart from each other, where the pad, when installed with a pedestal wear plate serves to improve the force load handling and preferably re-distributes the load bearing surface from the edges and center of the adapter to the flat load bearing surface of the adapter, thus eliminating load on areas that have no support. Because the spring arms do not depend on bending of the base for their resiliency, the pad of the invention provides improved service stress capabilities and allows for longer life of the wear plate.

摘要： A suspension device for supporting an air brake hose on a rail car is disclosed. The device includes a strap having a clevis at one end and a plurality of apertures in spaced relation lengthwise along the strap. A clevis pin is used to attach the clevis to a lug on the coupling of the air brake hose. The strap is inserted through a fitting on the coupler of the railcar and received within the bore of a collar. A through hole in the collar receives a strap pin that also extends through the apertures in the strap to lock the collar in place. The collar prevents the strap from passing through the bracket. The suspension device is provided as a kit wherein all of the components are integrally molded together and connected by sprue portions. A method of molding the device is also disclosed.

摘要： In a freight car truck assembly, an insert for converting a substantially flat, inclined, bolster pocket back wall into a pair of inclined surfaces for biasing a pair of split wedges laterally outwardly against side walls of the bolster pocket to create a space between the pair of split wedges. The insert is provided with a centrally located fin which projects into the space between the split wedges and engages against a side frame friction surface to control the location of the insert in the bolster pocket through frictional interference as the fin rubs against the friction surface. The insert can be loosely mounted in the bolster pocket without any need for welding the insert in place.

摘要： The coupler system of a railway car truck is constructed such that basic overall appearance may be maintained, but the actual material of which it is constructed is changed. According to one embodiment, the coupler is constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over ( )}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over ( )}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal coupler and components thereof. A second benefit of embodiments of the present invention provides for a more efficient use of materials, meaning less metal is used to make the same final shape, as a way of reducing the coupler weight. Both factures combined allow for a lighter weight coupler, while utilizing the standard designs. Alternate coupler configurations are disclosed for further reducing coupler weight.

摘要： Lightweight yokes are provided. According to some embodiments, the basic overall appearance of the yoke may be maintained, but the actual material of which it is constructed is changed. According to other embodiments, the yoke is provided with an improved lightweight construction, and, yet other embodiments the yoke may be provided with an improved construction and formed from a preferred material. Yokes may be constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over ( )}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over ( )}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal yoke. Yokes have improved configurations which may require less metal to produce the yoke. Both, the lightweight material and improvements in configuration of the yoke structure may combine to provide a lighter weight yoke.

摘要： A process for producing a coupler knuckle and an improved coupler knuckle design are provided. The process produces a coupler knuckle by constructing a mold having the shape of the coupler knuckle. The mold is coated with a material that is resistant to melting at the molten melt temperatures of the molten metal used to form the knuckle. With the mold coated, the cavities in the mold interior are filled by placing an inert material therein. The molten metal used for forming the knuckle contacts the mold and consumes it, while the coating serves to provide a shape for the knuckle.

摘要： A process for forming a cross-linked thermoplastic elastomer is disclosed herein. The cross-linked thermoplastic elastomer is a thermoplastic cross-linked copolyester and is preferably formed by heating a first mixture containing a thermoplastic elastomeric base material, a monomeric diisocyanate comprising between 1 to 10% of the total weight of the first mixture, and a second mixture of a first diamine and a second diamine comprising between 1 to 10% of the total weight of a total reaction product. The heated first mixture, which is flowable, is injected into at least one injection molding device, with the second mixture injected at predetermined intervals to create a homogeneous reaction product. The reaction product may be injected into a mold to produce articles.
