  • Drop bottom trucks or hoppers
    Patent number: 4781125
    Abstract: This invention relates to a hopper, and more particularly to a wheeled hopper for rail operation, including a container body which has a discharge opening in its underside, two doors which are pivotally connected to the body on opposite sides of its discharge opening with the pivot axes of the doors lying in the direction of travel of the hopper, the doors being movable between a first position in which they close the opening and a second position in which the opening is open, a door latch arrangement including an abutment formation on each door at one end of the hopper which, in the first position of the doors, are opposite and directed towards each other at a position above the pivot axes of the doors, a detent between the abutments for preventing movement of the doors from their first to second positions and means on the hopper body which is movable independently of the doors for moving the detent from between the abutments to enable the doors to move under gravity from their first to their second position
