| A horizontal loading platform is pivotally interconnected by a pair of spaced apart and opposed linkage systems, positioned on either side thereof. Each linkage system includes five pivotally interconnected links which are arranged so that a first common link is disposed above the loading platform and the points of pivotal interconnection of a first set of spaced apart links to the common link and to the loading platform define the corners of a first parallelogram. The points of pivotal interconnection of a second set of spaced apart links to said common link and to said framework define the corners of a second parallelogram. Thrust links, which includes an offset arm on the inboard link of said second set of links and a cross-link pivotally connected to said offset arm and to the outboard link of said first set of links, maintain said loading platform out of contact with the vehicle when the loading platform is away from rest position interior of said vehicle. The vehicle includes a raising and lowering mechanism coupled to the linkage system. | ||||||
| 283 | Brake mechanism for a gondola car loader | US949116 | 1978-10-06 | US4241811A | 1980-12-30 | Walter E. Buckner |
| The present disclosure relates to a brake mechanism, particularly useful on a vehicle which travels on the upper side wall edges of gondola cars. The brake mechanism includes a brake shoe rack which carries two pairs of brake shoes, one pair of brake shoes being adapted to clamp one side wall of the gondola car and the other pair of brake shoes being adapted to clamp the other side wall of the gondola car. The pairs of brake shoes are moved in opposition to one another by a single hydraulic ram to effect the clamping of the side walls. The brake shoe rack is pivotally supported below the chassis of the gondola car loader by hydraulic cylinders for raising and lowering the brake shoe rack as the vehicle is moved from gondola car to adjacent gondola car. The brake shoe rack is also movable from side to side with respect to the chassis of the vehicle to enable the brake mechanism to accommodate gondola car side walls which are bowed or otherwise irregularly shaped. | ||||||
| 284 | Overhead transfer carrier and tracks | US360527 | 1973-05-15 | US3939775A | 1976-02-24 | Leonard D. Barry |
| This invention improves upon my Pat. Nos. 3,483,829 and 3,484,002 and on my pending patent application titled CONTAINER OVERHEAD TRANSFER AND STORAGE SYSTEM Ser. No. 269,239, filed July 5, 1972, wherein the improvement comprises a cam track dip and container carrier for operating thereon to vertically transfer loads to and from a moving train. The cam dip serves to lower and raise a hook or load frame on the carrier to transfer one or more containers or cages to and from a train running parallel below. The hook or load frame is secured on double parallelogram linkage to the frame of the carrier and has outboard wheels for running on the cam track for parallel level movement of the frame down and up along the transfer dip. The hook or load lifting frame is hooked or latched to the carrier frame when lifted thereto and released by bars on each side of the carrier when these bars engage wheels positioned at the dip to release the hook or load frame for a transfer dip when the carrier is checked for register of container with empty spot on car in train to which the carrier is vertically coupled. This cam dip is further applied to carriers having a transfer container or cage as part of the carrier. The hook frame has container hooks which take less space to operate and are enclosed when opened so as not to interfere with the cam track. Where the container is moved along conveyor in car and shifted on carrier in station a stationary hooking arrangement is provided. | ||||||
| 285 | Loading apparatus for railroad flat cars | US29631372 | 1972-10-10 | US3868029A | 1975-02-25 | GOBY STEPHEN |
| A railroad flat car provided with a support plate positioned thereon for arcuate movement, and a pair of side frame members to engage opposed sides of a container to lift the same. A pair of powered piston and cylinder means operatively carried by the support plate, engage and control lever means operatively connecting the side frames to the support for load lift and/or control. The lever means and load will rotate with the support plate.

| 286 | Cargo handling mechanism | US3794193D | 1971-12-17 | US3794193A | 1974-02-26 | FLEENOR W |
| A cargo handling mechanism for use on an enclosing structure, such as a railroad car or the like, for loading cargo into or unloading cargo from the car. The cargo handling mechanism is preferably mounted in a vertical orientation for lateral movement, and has a door that is vertically movable to a selected position, and then pivotally movable in the selected position between open and closed positions. The cargo handling mechanism is a self-contained unit containing the controls and power source for laterally moving the mechanism, and vertically and pivotally moving the door. The lateral movement of the mechanism is desirable for horizontally aligning the door with a desired cargo space in the enclosing structure. Once aligned, the vertical movement of the door is desirable for aligning the lower end of the door with the cargo-supporting surface in the enclosing structure. The door is pivotally movable from a normaly closed position, in which it blocks entry to the enclosing structure and assumes a compact position for transport and handling of the mechanism, to an open position, in which the door forms a platform over which cargo may be loaded into or unloaded from the enclosing structure.

| Transfer of a load container from a truck to a railcar using a loading bolster to support and to swing the container into longitudinal alignment on the railcar during projection of the container onto the loading bolster by relative sliding movement between the container and the supporting surfaces of the truck, with transfer assisted by forward and reverse movements of the truck in directions transversely of the railcar.

| 288 | Railcar-unloading system | US3581918D | 1969-05-05 | US3581918A | 1971-06-01 | FUJIOKA RICHARD T |
| A railcar-unloading system comprising a wheeled vehicle such as a railroad flatcar or the like adapted to traverse a railroad track and having a generally flat horizontally extending cargosupporting bed; an elongated, generally rectangular-shaped cargocarrying container disposed on the cargo bed; means in the form of a plurality of pivotable and elevatable support mechanisms interposed between the lower side of the container and the upper side of the cargo bed and located one adjacent each of the four corners of the lower side of the container, whereby the container is adapted to the pivotably biased at each of the mechanisms between a transit position and a plurality of loading and/or unloading positions, and at least one transfer bridge assembly adapted to be selectively disposed at a support position extending outwardly from the cargo bed for supporting the cargo container when it is moved to and from its loading and/or unloading positions.
