摘要： An outlet assembly for application to hoppers of railroad hopper cars and the like, and slidably mounting a gate for movement between open and closed positions, in which the gate slideway is defined by trackway forming members disposed at either side edge of and across the mid portion of the gate outlet port, and having the respective load supporting surfaces each lined with a special liner formed from an ultra high molecular weight polymeric material that is of dry self lubricating characteristics. The gate side edges ride on the liners of the track forming members at the respective side edges of the outlet port, and the respective gate side edges and the liners supporting same cooperate to effect a bulk material seal at the respective side edges of the gate. The liner across the mid portion of the outlet assembly outlet port is mounted for limited lost motion movement relative to the gate and cooperates with a stop forming abutment to provide a gate break away action when the gate is opened under loaded conditions.

摘要： 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. The assembly includes a pair of pins secured across respective channels to engage the bent retainers to prevent the extension bars from sliding free of the sleeve.

摘要： This invention relates to a coupler shank bearing arrangement for supporting a railroad car coupler on its coupler carrier, and more specifically, to a railroad car coupler support arrangement in which the familiar coupler wear plate that rides on the coupler carrier is replaced by a bearing arrangement of the plane bearing type that provides for essentially wear free support of the coupler on its carrier. The coupler shank lower wall is formed with an elongate mounting slot at the location of application of the conventional wear plate, and extending longitudinally of the coupler shank, to which slot is applied a one piece bearing structure formed from an ultra high molecular weight polymer of dry self lubricating characteristics. The bearing structure is in the form of a one piece body shaped to define a lower generally planar bearing plate portion and an upper mounting portion in the form of an elongate ridge structure especially shaped for bond free but secure application to the coupler shank mounting slot.

摘要： 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.

摘要： An outlet gate assembly for application to hoppers of railroad hopper cars that is equipped with a self cleaning rack and gear door plate actuation arrangement, in which the outlet gate assembly includes a frame defined by a pair of spaced apart longitudinal frame members that parallel the path of movement of the door plate and a pair of spaced apart transverse frame members joined together with the longitudinal frame members to define the gate outlet port. The frame members are formed to define shelf portions on which the gate door plate underside rides, with the gate underside being equipped with several sets of self cleaning gear and rack mechanisms that couple the gate operating shaft to the gate door plate. The door plate is formed from an UHMW polymer material of dry self lubricating light weight characteristics and is supported across the midportion of the port by a pair of spaced apart support members in parallel relation across the gate outlet port. The gate assembly is equipped with a gravity operated self locking latch arrangement that holds the door plate in its closed position and also provides for sealing of the gate assembly, when the hopper is loaded, for transit.
