Abstract: An improvement to a collapsible stanchion on a railcar for supporting semi-trailers thereon. The improvement consists of a linkage which is activated by the pulling of a handle away from the stanchion during the operation of raising it from a resting position to an upright position. The linkage exerts a force on a diagonal support member of the stanchion to urge it into a position where the stanchion's locking mechanism may be engaged to lock the stanchion in an upright position.

Abstract: A restraint for a parked swap body container includes a face stop that can be selectively positioned to a restraining position and a release position. In the restraining position, the face stop is adapted to engage a front face of the container to limit the extent to which the parked container can move away from an edge of a truck loading dock. In The release position, the face stop allows a truck to remove the container from the loading dock. The restraint may also include a frame that can be repositioned longitudinally to accommodate containers of various lengths. A fine adjustment can be added to further limit horizontal movement of the container. And an optional bottom support could engage the bottom of the container to provide even more support.

Abstract: A see-saw motion loading device for a loading platform makes use of an auxiliary chassis installable on the frame of a vehicle carrier. At least one see-saw motion rocking member cooperates with a fixed base, and preferably also with a base movable towards and away from the fixed base. A device, such as a hydraulic jack or the like is provided for opening and closing of the see-saw motion rocking member.

Abstract: A retarder (97) for a railcar hitch (1) is disclosed. The hitch has an erected and a retracted position and the retarder slows movement of the hitch towards its retracted position. The retarder comprises a cylinder (99) fixedly mounted on a railcar. A piston (101) is movable in the cylinder. A rod (115) attaches the piston to the movable hitch element so that preferably only axial loads act on the piston during operation of the hitch. The fluid compressed in one end of the cylinder by the piston is bled (metered) from the one end of the cylinder so as to control the rate of movement of the movable element during hitch retraction.

Abstract: An elastomeric in compression trailer hitch cushion for an over-the-road trailer hitch, as mounted on a railway car, is disclosed so as to cushion against longitudinal loads transmitted between the railroad car and the trailer. This trailer hitch cushion serves as the hitch diagonal strut and it has one end thereof secured to the railway car and its other end secured to the vertical hitch strut, with the diagonal cushioning strut being disposed so as to cushion longitudinal loads in either fore or aft direction and to maintain the vertical strut in vertical position. The cushioning strut comprises a frame, compressible elastomeric cushioning members carried by the frame, and a compression load applying system for compressing the elastomeric members relative to the frame upon a longitudinal load in either fore or aft directions relative to the railroad car being applied to the hitch.

Abstract: A trailer hitch for securing trailers to a platform or deck of a railway flat car comprises an upright pedestal pivotally connected so that it and a fifth wheel plate can be attached to the kingpin of a trailer. The hitch includes a diagonal assembly pivotally connected to the pedestal and being rockable therewith. The diagonal assembly comprises diagonally extending outer thrust members and a central thrust member. A pair of laterally spaced upright support plates are rigidly connectd to the platform or deck. The outer thrust members support in spaced relation a plurality of resilient members on their inner surfaces. The resilient members are also connected to the support plates. Other similar resilient members are connected to the inner surfaces of the upright support plates and these are also connected to the central thrust member thereby providing a completely cushioned trailer hitch.

Abstract: Disclosed is an articulated rail car for transporting two large wheeled vehicular truck trailers in "piggyback" fashion. The articulated rail car comprises two separate car bodies each supported by single axle railroad wheel truck assemblies mounted at each end of each body. A semi-permanent coupling joins the two car bodies so that the car can articulate around curves and bends in the railroad track. Utilization of the single axle trucks permits the rail car to maintain the normal number of axles (four) for rail cars even though the car is articulated in the center. The car bodies comprise a central spine extending upwardly along the length of the car for providing vertical strength. A tire support surface extends outwardly from each side of the central spine below the level of the central spine so that the vertical height of the wheel vehicular trailers transported by the articulated rail car is reduced allowing easier passage under structures and through tunnels.
