  • Patent number: 6074159
    Abstract: A truck box divider is installed in a truck box to divide the box into a front chamber and a rear chamber for carrying different materials, for example seed and fertilizer. The divider includes a V-shaped divider mounted midway along the box with the apex directed towards the back end of the box. A tunnel tapering in height leads from the back end of the V shaped box separator to a gate at the back of the truck box. Two additional side gates are positioned on opposite sides of the tunnel gate.

  • Patent number: 5186376
    Abstract: A dispenser is used for dispensing plastic film from a roll. The dispenser has a housing that may be mounted under a shelf or cupboard or on a wall. The housing consists of a cover unit that is installed in the place of use and a releasable base unit that fits into the bottom of the cover unit and is held in place with resiliently biased locking tabs. The base unit carries the roll of film, so that the roll is readily installed on the base unit when separated from the cover. The loaded base unit is easily lifted into place. The film is dispensed through a dispensing slot at the back of the base unit. Lengths of film are severed using a cutter at the front of the base unit. The length of film between the dispensing opening and the cutter is prevented from clinging to the underside of the base unit by using a non-planar, roughened surface on the under side of the base plate.

  • Patent number: 4779780
    Abstract: Conventional film wrap dispensers have an exit slot adjacent the cutting blade so that the film end is difficult to grasp and pull out of the dispenser. The present device has a dispensing slot in the base adjacent the rear thereof and spaced from the cutter blade so that there is a two or three inch strip of plastic film extending from the slot after the previous length has been detached by said cutter blade. Furthermore, the transverse portion between the dispensing slot and the cutter blade is formed from a material which inhibits the usual adhesion of the plastic film so that the strip of plastic film extending from the dispenser slot normally hangs downwardly clear of the dispenser and does not adhere to the portion of the base between the slot and the blade as is usual. Even if some light adhesion does take place, the strip is easily detached so that it may be grasped easily for withdrawal, remote from the cut-off blade.

  • Patent number: 4712821
    Abstract: When dumping grain from a truck box through the tailgate opening, grain lodges in the corners upon each side of the tailgate opening and the operator normally has to stand on the auger or the like in order to reach over the tailgate with a shovel and is therefore at risk due to the danger of slippage with the danger perhaps of coming into contact with the rotating discharge auger assembly. The present device consists of a handle and an arcuately curved rake blade secured at one end with the major portion of the blade extending on one side thereof. This can be engaged within the tailgate opening and reaches into each back corner of the box thus enabling the operator to pull the lodged grain towards the opening readily and easily.
