  • Patent number: 4419037
    Abstract: An auger-hopper construction for mounting at the tailgate of a truck includes a pair of hoppers, one of which is stationarily and removably mounted to the truck, and the second of which is pivotally mounted to the first hopper adjacent an opening in the bottom of the first hopper. The second hopper also includes an opening adjacent its bottom at which an auger tube is swivelly mounted. The auger tube, by virtue of the pivotal and swivel mountings is pivotable in a 90.degree. arc in a plane perpendicular to the axis of the pivotal movement and is swivelable in a 180.degree. arc in a plane which is parallel to the axis of the pivotal movement.

  • Patent number: 4411581
    Abstract: Auger-hopper constructions for mounting to an inclinable body of a truck at the tailgate of the truck includes a pair of hoppers, one of which is stationarily and removably mounted to the truck, and the second of which is pivotally mounted to the first hopper adjacent an opening in the bottom of the first hopper. The second hopper also includes an opening adjacent its bottom at which an auger tube is swivelly mounted. The auger tube, by virtue of the pivotal and swivel mountings, is pivotable in a 90.degree. arc in a plane perpendicular to the axis of the pivotal movement and is swivelable in a 180.degree. arc in a plane which is parallel to the axis of the pivotal movement. Both the first and second hopper are dimensioned and positioned such that no portion of either of the hoppers extends substantially beneath a plane defined by the bottom of the inclinable body of the truck.
