  • Patent number: 11142228
    Abstract: A cushioning apparatus for a railway car employs a shortened yoke with a reduced-width tail for placement between stops in a conventional railway car sill. A first stack of rigid plates with elastomeric pads is provided between the straps of the modified yoke behind the coupler follower, and a second stack of plates and elastomeric pads is positioned in the sill behind the modified yoke to absorb buff loads on the coupler. In embodiments, the entire assembly may be placed in a sill having forward stops, intermediate stops, and rear stops, adapted to house a hydraulic cushioning unit.

  • Patent number: 7055705
    Abstract: A central buffer coupling for coupling a first rail car body with a second, adjacent rail car body of a multiple-unit rail vehicle, has a coupling head pivotally connected by a coupling shaft to a linking housing of the rail car body, and a pivoting unit pivoting the coupling shaft. The pivoting unit has a guide participating in horizontal pivoting of the shaft that runs about a vertical pivot axis. Pressure surfaces symmetrical to the longitudinal axis of the shaft which correspond to a respective pressure device, bring about horizontal re-centering of the shaft. The respective pressure devices are supported on the linking housing of the shaft to bias the related pressure surfaces against the guide. The guide is positionable with the action-linked coupling shaft in every position of the planned pivot region, via an activation device.

  • Patent number: 4344541
    Abstract: A coupler carrier arrangement for railroad cars, in which the car center sill ends are equipped with a striker casting through which the car coupler shank extends for connection to the car center sill, with the striker casting having the familiar cage, in which the coupler carrier is mounted, including an upwardly opening socket on the underside of the casting defining a coupler carrier chamber, in which the coupler carrier itself comprises a body formed from an ultra high molecular weight polymer of dry self lubricating characteristics that replaces both the conventional coupler carrier and the carrier iron, and is shaped to define a horizontally disposed upwardly facing load support surface on which the coupler shank rests, and oppositely facing forward and rearward side walls defining vertically disposed slide surfaces formed for close fitting relation to the coupler carrier chamber inner and outer walls.

  • Patent number: 4249664
    Abstract: A rigidifying arrangement for self lubricating wear plate assemblies employed for supporting the inner end of the vertical yoke used in railroad car coupler draft gear rigging, in which the wear plate is in the form of a planar support plate equipped with the special liner of Chierici and Murphy U.S. Pat. No. 4,055,254 for supporting the yoke inner end at its operative level within the car center sill. The support plate is rigidified to maintain its planar configuration under the weight of the draft gear and yoke acting on it, by affixing to same along its longitudinal center line a depending flange structure defining a vertical flange of rectilinear configuration and a horizontal flange integral with the vertical flange along the lower edge of the latter and spaced from the support plate.

  • Patent number: 4120404
    Abstract: 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.
