  • Patent number: 4527736
    Abstract: A mount for a railroad rail having an inner side turned toward another such rail and an outer side turned away from the other rail has a one-piece base supported on the ground under the one rail and formed with an upwardly open recess having inner and outer base flanks respectively generally under and parallel to the inner and outer sides, the outer base flank being formed as an inwardly overhanging ridge. An insert attached to the rail and received in the recess has respective inner and outer insert edges, the former of which is overhung by the ridge. An elastomeric body lies between the inner flank and inner edge and supports the insert in the base. Due to the overhang of the base edge, it is possible to make the base in one piece at least outward from a location underneath the rail. Thus there is no need to make the base from two parts split along a horizontal plane and requiring tedious assembly in the field.

  • Patent number: 4515506
    Abstract: A cargo restraining device for a palletized load including a platform for receiving a pallet with a load of cargo thereon, and a vertical frame at one end of the platform. A handle is pivotally secured to the frame and connected to a horizontally-extending member which is movable to place it in frictional contact with a floor or supporting surface. When the pallet is placed on the platform, it can be locked in place by a serrated member which engages a cross-tie of the pallet. To lock the pallet and platform to the floor, the handle is pushed downwardly while at the same time pushing the frame toward the load. Movement of the handle, which pivots about a hinge pivotally connected to the frame, moves the horizontally-extending member into contact with the supporting surface and at the same time lifts and tilts the platform, which adds an augmented downward force on the horizontally-extending member in contact with the supporting surface.

  • Patent number: 4512260
    Abstract: The piston rod of at least one hydraulic cylinder is axially connected to a pivot pin about which the car holding arm of a car holding device rotates in a vertical plane to engage the couplings between railroad cars. In the case of a single hydraulic cylinder, the inner chamber of the cylinder, located closest to the car holding arm, is connected to the outer chamber on the other side of the piston by a conduit. When hydraulic cylinders are connected to each pivot pin of the car holding arm, the inner chambers of the two cylinders are interconnected by a conduit as are the two outer chambers. When flow through the conduits is blocked by a solenoid valve, movement of the car holding arm in the direction parallel to the track is resisted and the arm holds the train in position.

  • Patent number: 4510871
    Abstract: A bogie for a railroad vehicle comprises a pair of wheel sets mounted in a frame which is pivotally connected to the vehicle so that it can rotate about a substantially upright axis. The wheel sets are connected to the frame resiliently and by links which, upon the application of unbalanced force, axially to one of the wheel sets shifts the force-receiving end toward the other wheel set. The links can also be disposed so that any tendency for one of the wheel sets to move downwardly relative to the frame will result in a tendency for it also to move closer to the other wheel set. This has been found to increase high speed stability of the vehicle.
