  • Patent number: 8413787
    Abstract: A sweeper sorting apparatus for use with a transport belt includes first and second drive belts and a sweeper. The first and second drive belts are positioned adjacent to first and second ends, respectively, of the transport belt and have upper portions oriented substantially parallel to and below an upper surface of the transport belt. The second end of the transport belt is opposite the first end of the transport belt. The sweeper is coupled at a first end to the first drive belt and at a second end to the second drive belt. The sweeper is positioned above the upper surface of the transport belt. At least one of the first drive belt and the second drive belt is operable to move the sweeper across the upper surface of the transport belt to push an item off the upper surface of the transport belt.

  • Patent number: 8397901
    Abstract: An extendable boom conveyor system and method. The extendable boom system includes first and second boom elements, an operator control, and a controller. The first boom element includes a brake mechanism, which includes a pin configured to be positioned in an engaged position and a disengaged position. The second boom element includes a feature configured to engage the pin in the engaged position and prevent motion of the first boom element relative to the second boom element in at least a first direction. The controller is configured to receive an operator signal from the operator control and activate the brake mechanism responsive to the operator signal.

  • Patent number: 7191965
    Abstract: A material spreader includes a belt/chain assembly. The belt is mounted within the chamber of the material spreader and the chain remains out of contact with the material during the operation of the device. A sliding barrier is mounted at the rear of the belt, and moves from a forward position adjacent the front of the spreader to a rear position adjacent the rear of the spreader. One form of the hydraulic system utilizes a sensor for built up pressure within independently driven augers. In response to this pressure build up the sliding barrier speed is reduced.
