  • Patent number: 6321758
    Abstract: The present invention relates to a method for transferring harvested tobacco leaves from an amorphous mass of harvested tobacco leaves to a bulk curing container component for subsequent transfer to a bulk curing site. According to the method, the bulk curing container component is positioned adjacent a tobacco discharging end of a tobacco transferring system. The transferring system has the discharging end, a tobacco receiving end opposite the discharging end, and a generally upwardly facing tobacco conveying apparatus for supporting and moving the leaves between the discharging and receiving ends.

  • Patent number: 5156518
    Abstract: An unloading device having a frame transversely supportable on a pair of spaced side walls of a truck bed is longitudinally movable from the front to the rear of the truck bed. A plurality of wheels secured to the frame and engagable with the side walls facilitate movement of the device. An electric motor or hand crank is drivingly connected to a main shaft mounted on the frame for rotating the shaft in opposite directions, and an elongated sheet of material, such as reinforced nylon, having one end thereof secured to the shaft and the other end thereof secured to the rear of the truck bed is used for receiving an article for transportation. Rotation of the shaft in one direction winds the sheet of material on the shaft, moves the frame toward the rear of the truck bed and shifts the article on the sheet from the front of the truck bed to the rear and off of the truck bed.

    Abstract: Grain tanks of harvesting machines frequently have an irregularly shaped interior which is difficult to fill completely and to unload. A conveyor system is proposed facilitating loading and unloading of the grain tank. The conveyor system comprises a conveyor arrangement which contains conveyor elements that can be driven and that can be moved vertically depending on the height of the crop deposit. The conveyor arrangement is mounted to the interior wall of the grain tank by a four bar linkage. During the filling process, the conveyor elements act as distributors filling in unused areas of the grain tanks. During the unloading process, they act as conveyors directing grain to the unloading auger.

  • Patent number: 4526499
    Abstract: An improved rail lock for the meat transportation industry has a pair of legs which extend below the rail. The inner surface of one of the legs is substantially flush against a side of the rail. A first clamping means is carried by the other leg and bears against the other side of the rail, thereby exerting a force tending to spread the legs apart. A second clamping means is carried by the one leg, just below the rail, and exerts a counterforce tending to bring the legs together. As a result, the rail lock is rigidly retained on the rail and will not vibrate loose during transportation, thereby solving a vexatious problem in the meat industry.

  • Patent number: 4522296
    Abstract: A flail auger assembly is disclosed which is useful for unloading semi-liquid material from a holding tank mounted on a tractor drawn trailer. A rotatably mounted shaft extends lengthwise through the lower portion of the tank. One end of the shaft penetrates the front wall of the tank enabling connection with the power takeoff of the tractor. The second end penetrates the rear wall of the tank where it connects with the impeller of the discharge pump. A plurality of flails extend radially outward at regular intervals along the shaft. The flails are pivotally attached via pins which secure them to brackets welded to the rotatably mounted shaft. The pivotal axis of each flail allows it to aggressively attack the material in the tank while at the same time limiting the power drain on the tractor since the radius of effectiveness decreases as a function of increasing load.
