  • Patent number: 4629203
    Abstract: A utility cart especially suited for snow removal and other yard work and comprising a generally rectangular body having side panels, a rear panel, and a bottom panel. A pair of wheels are provided at the rear of the body for rollably engaging a support surface and a rounded nose is provided at the front of the body. The rounded nose normally slidably engages the support surface but is rollably engagable with the support surface in response to a generally upward force applied to handle at the rear of the body to facilitate upward rolling pivotal movement of the cart about its nose to dump the contents of the cart out of the open front end of the body. The cart is particularly suited for snow removal but, because of the basic open box configuration of the body, has general application for year round yard work.

  • 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.
