  • Patent number: 4353596
    Abstract: A break down dumping cart is disclosed including a hopper and a support structure which operably supports the hopper and which can be disassembled and stored within the hopper for compact storage and shipping. The support structure includes a pair of side frame members and a number of associated bracing members which cooperate to bracket the hopper on three of its sides, pivotal support members attaching one of the side frame members to the hopper, pivotal over center lever members attaching the other side frame member to the hopper, an axle and wheel assembly attached to a lower section of the side frame members, and a pair of handle members attached to an rearwardly extending from respective ones of the side frame members.

  • Patent number: 4313701
    Abstract: In an exemplary embodiment, a U-shaped bracket forms pivot pins by means of the bent-out end areas of the bracket arms, which pivot pins are insertable (and held by the resilience of the bracket) in recesses of the car container sidewalls. The U-shaped bracket has its respective arms engaging in lateral slots of the container insert. The removable container insert may be lowered into engagement with the U-shaped bracket after assembly of the bracket with the car container, with the dimensioning such that the container insert prevents disengagement of the retaining pins. Outwardly inclined parts of the bracket arms may engage in close fitting elongated slots of the container insert so that the container insert pivots as a unit with the supporting bracket.

  • Patent number: 4070060
    Abstract: A manually operated dump truck is provided with front wheels which are located and mounted on the bottom of the truck, as for example, on swivels, so that they are selectively movable from a forward position substantially in advance of the center of gravity of the truck, which is the position selected when the truck is being loaded or used as a conveyance, to a position more closely adjacent the center of gravity when the truck is to be dumped thus reducing the amount of energy required to tip the truck forwardly in a dumping action. Manually controlled latching means is provided to maintain the wheels in the forward position.
