Abstract:
1. A dumping container moveable by a dumping vehicle between an on-the-ground position and a tilted position sufficient to enable at least some of the contents of the dumping container to be dumped therefrom and having at least one lid thereon moveably mounted for movement between a closed or substantially closed position when said dumping container is in its on-the-ground position and a non-closed position when said dumping container is in a tilted position sufficient to enable at least some of the contents of the dumping container to be dumped therefrom and a system having a lid-restraining mode and a lid-release mode, the lid-restraining mode for restraining the lid in a closed or substantially closed position when the dumping container is in its on-the-ground position and the lid-release mode for releasing the lid from its lid-restrained mode when the container is tilted toward a position sufficient to enable at least some of the contents of the dumping container to be dumped therefrom, comprising: a bail moveable between a lid-restraining position and a lid-release position in which the lid is not restrained from moving toward an open position, the bail connected to the container at a pivot connection for rotatable movement thereabout between said lid-restraining position and a position in which the lid is not restrained from moving toward an open position; a member connected to the bail at the pivot connection for rotation therewith; a swing-arm pivotally connected at a proximate end thereof, directly or indirectly, to the container and having a remote end thereof moveable through a range of motion as the container is tilted from an on-the-ground position to a tilted position sufficient to enable contents of the dumping container to be dumped therefrom; a link having one end thereof pivotally connected to the swing-arm at a position spaced from said pivotal connection at the proximate end of said swing-arm and having the opposite end thereof pivotally connected to said member at a position spaced from said pivot connection of said member; a trigger pivotally mounted at a position intermediate its ends thereof, directly or indirectly, to the container and having a latching element at one end thereof for selective engagement with said member to arrest the movement thereof and having a weight distribution thereof at or adjacent the other end thereof whereby, when the container is in its on-the-ground position, the force of gravity acting on said trigger biases said trigger to enable said latching element to engage said member to arrest movement of said member with said bail in said lid-restraining position and, when said container is tilted toward its tilted position sufficient to enable at least some of the contents of the dumping container to be dumped therefrom, to bias said trigger to disengage said trigger from said member to allow said bail to move to a position in which said lid is not restrained from moving toward an open position sufficient to enable dumping of at least some of the contents of said container.
