  • Patent number: 7350872
    Abstract: A wheel supported grain wagon includes a container with sloping side walls extending to an incline bottom wall, and a gravity discharge opening is formed within one of the side walls adjacent the bottom wall. A door panel is supported by tracks for movement between an upper open position and a lower close position covering the opening. A grain discharge chute extends from the opening and has opposite side walls connected by a bottom wall. The chute is adjustably supported by a pair of horizontally aligned pivot pins projecting into corresponding slots within a pair of side support brackets secured to the container. The slots extend generally perpendicular to the side wall and have longitudinally spaced bottom notches which selectively receive the pivot pins in response to manually lifting and shifting the discharge chute for selectively positioning the outer edge of the discharge chute at different elevations.

  • Patent number: 6497546
    Abstract: A grain wagon includes a wheel supported frame on which is mounted a hopper or container for receiving grain, and the wagon is pulled by a tow vehicle or tractor. An inclined discharge auger conveyor has an outer section which folds between a stored position and an operating position projecting upwardly and forwardly and laterally outwardly from the container. The outer auger section has a pivotal discharge spout with a pivotal internal baffle, and the spout is actuated by a double acting hydraulic cylinder controllable through hydraulic lines from the cab of the tractor so that the tractor operator may fully load and “top off” the grain within an adjacent semi-trailer as the tractor operator pulls the wagon along the side of the semi-trailer. In one embodiment, the outer section of the auger conveyor has an outer telescopic housing extension which carries the discharge spout and extends and retracts automatically with folding of the outer auger conveyor section.

  • Patent number: 6095616
    Abstract: A wheel supported grain wagon includes a box or container with sloping side walls extending to a bottom wall, and a discharge opening is formed within one of the side walls adjacent the bottom wall. An inner metering door or panel and an adjacent outer closure door or panel are supported by parallel spaced dual tracks for movement between lower positions closing the discharge opening and retracted upper open positions. An actuator first raises the outer closure panel to permit grain to flow through a metering passage defined by the bottom edge of the metering panel and to release grain pressure on the metering panel. The metering door is then elevated in response to further elevation of the outer closure panel so that grain flows smoothly under both panels without obstructions.
