  • Patent number: 4454953
    Abstract: A three-part telescoping uncoupling lever assembly is disclosed for railroad cars which are equipped with standard draft gear cushioning. The assembly includes a plastic sleeve formed from ultrahigh molecular weight polyethylene (U.H.M.W.) and a pair of unitary extension bars in sliding engagement within the sleeve. One end of each extension bar is bent to form a lock lifter hook or a handle for performing the uncoupling function. Each extension bar includes a shaft and an integral bent retainer, the bent retainers being positioned within the sleeve. The retainers are maintained in parallel sliding arrangement within juxtaposed channels extruded in the U.H.M.W. polyethylene sleeve. The hook and the handle are located on opposite ends of the assembly, the total length of which can be varied automatically between maximum and minimum lengths, dependent upon the corresponding distance between the coupler and sill bracket as that distance changes due to coupler impact and side swing.

  • Patent number: 4427471
    Abstract: A composite coupler carrier assembly for railroad cars comprising a lower metallic attachment plate shaped and arranged to be mounted on the car structure supporting the coupler shank, and an upper planar polymeric bearing body of ultra high molecular weight polyethylene that defines an upwardly facing planar bearing surface on which the coupler shank rides. The metallic attachment plate and the polymeric bearing body are fixed to each other by the practice of a spin welding technique involving the forming of a plurality of apertures of frusto-conical edging in the attachment plate, in which the small sides of the apertures are on the same side of the plate, and placing the underside of the polymeric bearing body against said side of the mounting plate, and spin welding in each aperture, to the bearing body, a polymeric disc that is of the same material as the bearing body, and that is proportioned to thereby anchor the attachment plate to the bearing body.

  • Patent number: 4079818
    Abstract: A support arrangement for brake rods of railroad car brake rigging comprising a U-shaped support member suspended from the underside of the car, a slotted sleeve snap fitted on the brake rod and located to rest on the bight portion of the support member, with the slot facing upwardly, and a retainer member comprising a shank portion received in said slot and having its end portions extending beyond the ends of the sleeve and enlarged to embrace the upwardly facing side of the brake rod on either side of the sleeve slot, with the retainer member end portions being bonded to the brake rod. The sleeve is formed from an ultra high molecular weight polymer material that is of dry self-lubricating nature and resists adherence thereto of foreign materials and serves as a sound deadener and energy absorber. Such material is also characterized by its polishing action on the brake rod support surface it rides on to reform same to define a mirror finish that substantially inhibits further wear on the support during use.

  • Patent number: 4075951
    Abstract: A self lubricating liner for railroad car center plate assemblies comprising a bowl shaped member formed from an ultra high molecular weight polymer of dry self lubricating characteristics and shaped to define a floor portion and an upstanding side wall. The liner is stretch resistant and is received within the trunk bolster bowl on the floor of the bowl, it being proportioned to be fit on the bolster center plate and to entirely fill the space between the truck bolster bowl and the body bolster center plate 360.degree. about the side wall of the bowl to preclude high energy impacts between these parts when coupler impacts and train line action are occasioned. The liner side wall is formed to be spaced from the top surfacing of the bowl side wall and make a tight seal about the neck of the bolster center plate. In use, the liner effects resurfacing action on the surfaces engaging same to make them effectively resistant against wear.
