  • Patent number: 4445437
    Abstract: A tamping machine intended for tamping on the open track and below switches and cross overs. It is equipped with independent tamping units arranged on opposite sides of each line of rail and each connected to the chassis by a mechanism comprising: a transverse slideway actuated by a first piston-cylinder unit; a slide block mounted on the slideway and on which the tamping unit is articulated; an arm fastened to the tamping unit; and a connecting rod connecting said arm to the chassis. The slide block of the outer unit is fastened on the slideway while the slide block of the inner unit is movable on said slideway and driven by a second piston-cylinder unit. Thus, the transverse trajectory of the tamping tools is sufficiently flat to avoid a correction of their depth of penetration upon the tamping of long ties.

  • Patent number: 4445618
    Abstract: A rotary railroad car coupler assembly is described as having a unique carrier which is designed for limited angling or tilting in the vertically elongated chamber of the striker, as the coupler rotates. The projecting lugs of the carrier which interlockingly engage the stops in the chamber of the striker, have sloping sides which diverge from the sidewalls of the chamber in a direction away from the coupler, rather than being parallel to the sidewalls as are the sides of the lugs of AAR Standard carriers. This improvement eliminates chattering that is normally occasioned when AAR Standard carriers are used in connection with a rotary railroad car coupler assembly and helps to prevent undue stress of the striker caused when the carrier becomes momentarily frozen or bound up in the striker as the coupler rotates.

  • Patent number: 4441431
    Abstract: A pivoting hatch cover and strap assembly has an overcenter latch assembly which is pivotably mounted upon the car roof at a location opposite the common hatch cover and strap pivot axis. This latch assembly includes a bifurcated overcenter locking handle which has a pair of cam surfaces which in closed position engage spaced wear plate surfaces located on the strap. A tab is located on the wear plate adjacent to but outboard of the cam surface on the operating handle. The tab makes a sufficient angle with the horizontal and extends upwardly and outwardly from the cam surface a distance sufficient to prevent the cam portion of the operating handle from moving longitudinally, and disengaging from the strap until pressure within the car is dissipated and thus prevents the strap and cover flying open.

  • Patent number: 4436466
    Abstract: A cargo restraining apparatus is disclosed which is designed to confine and restrain a load during shipment in a transport vehicle, and which comprises a rectangular panel, and a continuous flexible loading strap mounted in a figure eight pattern on one side of the panel. A tie strap is mounted at each of the four corners of the panel for securing the panel to an adjacent anchoring structure in the transport vehicle, and a belt and buckle arrangement is provided for drawing the ends of the strap together to thereby adjust its length. When operatively positioned against one end of the load, the panel acts to spread the contact pressure over a relatively large area, and the loading strap serves to reinforce and support the panel.
