  • 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: 7134830
    Abstract: A grain wagon includes a wheel supported frame supporting a container having inclined front and rear walls connected by opposite inclined side walls. Each side wall has inwardly projecting wall portions defining a wheel well for receiving longitudinally offset dual wheels or extra wide wheels. The rear wall includes a portion sloping between the wheel well wall portions to a forward grain removal zone, and generally triangular diverter walls extend from the rear wall to the wheel well wall portions. A corner discharge auger conveyor extends from the grain removal zone and has an upper portion which pivots to a stored position adjacent the front wall of the container. The dual wheels are positioned within the wheel wells by support members having end portions pivotally connected to the wagon frame and opposite end portions connected to the frame by laterally slidable clamping plates.

  • 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.

  • Patent number: 6047989
    Abstract: A self-propelled grain combine head is transported on a wheel supported trailer having an elongated lower support bar on which is mounted a pair of slidable head support units each having a bracket supporting a repositionable support member. Each support member has peripherally spaced different support surfaces for receiving frame members of different combine heads, and each bracket and corresponding head support member have a plurality of sets of alignable holes for receiving a pair of removable cross pins. A pair of hold down units are also slidably mounted on the lower support bar, and each unit carries a manually actuated ratchet winch having a flexible hold down strap. Each strap is connected to a combine head by a hook which may also receive a claw-type hook and a cross pin.

  • Patent number: 5615990
    Abstract: A wheel supported wagon includes a gravity discharge container or hopper for directing grain, feed, dry fertilizer or other granular material into a receiving box mounted on the side of the hopper. An inclined elongated auger unit includes a tubular conduit enclosing a hydraulically driven auger, and the lower end portion of the conduit has an inwardly projecting and upwardly curved annular upper flange. The flange seats on a downwardly projecting and outwardly curved lower flange forming part of an annular auger support member projecting downwardly from the material receiving box. The mating flanges provide for rotating the auger unit on a vertical axis and also for tilting the auger unit in a vertical plane at any selected rotational position.

  • Patent number: 5340265
    Abstract: A wagon for transporting grain and other particulate matter. The wagon is adapted to be attached to a tow vehicle. The wagon has a container which is provided with a forward wall. Within the container is a conduit. The conduit has a part which protrudes outwardly from the container and forwardly from the forward wall. Within the conduit is an auger. Pivotally attached to the part of the conduit which extends outwardly from the forward wall is a conduit extension member. The conduit extension member is pivotally movable to a position extending from the forward wall. Within the conduit extension member is an auger extension member. The auger extension member is operatively connected to the auger when the conduit extension member extends from the forward wall. Thus, a condition is established for discharging grain from the container of the wagon. The conduit extension member is pivotally movable to a position closely adjacent the forward wall.

  • Patent number: 4522578
    Abstract: This invention relates to insulated pipe and methods and apparatus for making the same. There has been difficulty in placing foamable insulating materials in the narrow elongated space between a casing pipe and a core pipe. According to the instant invention, a miniaturized mix head is inserted in this elongated space. Constituents of the foamable insulating material are simultaneously mixed and disseminated by the mix head in a manner to create a moving foam front which displaces air within the elongated space and permits the formation of a layer uniform, low density insulating material therein.

  • Patent number: 4024939
    Abstract: A gravity type box for a farm wagon, in which the box has a single opening and provides either side or center delivery of flowable material from the box. The opening in the box is in a lower portion thereof and is closed by a sliding door. Two chutes are attached to the box adjacent the opening. The chutes are arranged so that grain flowing from the box through the opening is discharged from either one of the chutes. One chute is adapted to discharge flowable material from the box toward a position below the box, and the other chute is adapted to discharge flowable material from the box to a position at the side of the box.
