  • Patent number: 6283697
    Abstract: The invention is directed to a mobile bin device having a mobile bin with a first conveyor extending along the bottom of the bin beneath a bin opening to convey material in the bin to one end of the bin. A second belt conveyor has one end pivotally mounted to the one end of the bin to pivot relative to the bin upward and downward and to one side or the other. The second conveyor is slidably mounted in its pivotal mounting to side longitudinally in the mounting to along the one end of the bin beneath the one end of the first conveyor to shorten or lengthen the distance from the outer end of the first conveyor to the outlet end of the second conveyor at the one end of the bin. Power devices are provided to power the upward and downward movement of the second conveyor and the longitudinal movement of the second conveyor.

  • Patent number: 5273211
    Abstract: The invention comprises a mobile trailer having a frame with a set of wheels on the frame for hauling the trailer and a pair of storage bins on the frame in side by side spaced relation with one bin adapted to a receive peat with a mixing blade to mix the peat and the other bin adapted to receive sand. The bins have openings along their bottoms and connecting openings along their vertical front walls with vertically adjustable plates to vary the sizes of the vertical openings. Horizontal conveyors are mounted beneath the bottom openings to the bins. Collecting and mixing blades are in the front of the trailer and a rotating spreader mounted to the rear upper portion of the trailer. An inclined conveyor is mounted with its lower end beneath the mixing blade and its upper end above the spreader.

  • Patent number: 5014893
    Abstract: A luggage rack is provided for mounting on the roof of a vehicle. The luggage rack includes a pair of elongated side rails securable to the roof. A slot is provided in each slide rail to receive the tongue of a stanchion. A detachable cross member extends between stanchions provided on each side rail. The stanchions permit slidable adjustment of the cross member along the length of the side rails. The tongues of the stanchions and the slots in the side rails are angled outwardly to prevent removal of the stanchions and cross member after they are mounted.

  • Patent number: 4643370
    Abstract: A vehicle for stringing cable from a spool. A motor may be used to rotate the spool, and a multibrake system may be used to inhibit the rotation of the spool. The brake system includes a variable, light resistance brake capable of being activated when the vehicle is either moving or parked and includes a nonvariable, strong resistance brake capable of being actuated only when the vehicle's parking brakes are used. When the strong resistance brake is applied and thereafter the motor is used to rotate the spool to take in or pay out cable, the strong resistance brake is automatically disengaged during such rotation and is automatically reapplied when such rotation ceases.

  • Patent number: 4353201
    Abstract: Our transfer mechanism is attached to the front of a conventional combine. The transfer mechanism includes a number of longitudinally spaced rows of laterally spaced curved teeth or tines that move rearwardly and upwardly so that the tines of each row successively engage a growing or standing crop, such as pinto beans or field peas, lifting the crop sufficiently so that the cutter bar of the combine effectively severs the crop adjacent the surface of the ground. Continued rearward and upward movement of the tines, while still engaging the severed crop, transfers the crop to a more elevated location adjacent the auger. When the tines reach the auger, the shaft on which those particular tines are mounted is angularly rotated so as to release or dump the severed crop onto a curved floor beneath the auger. The auger moves the cut crop laterally and then rearwardly into the threshing portion of the combine.
