Abstract: A hopper (10, 120) for use with flowable material (12) such as particulate, aggregate, sand, salt, gravel, top soil or the like includes at least one pivotal gate (14) attached to a frame (18) of the hopper (10, 120). Advantageously, the gate (14) swings toward an open position in response to the weight of the material (12) in the hopper (10, 120) to allow the material (12) to flow out of the hopper (10, 120). Additionally, the gate (14) automatically returns toward the closed position by gravity due to the position of the pivot axis of the hinge (16) connecting the gate (14) to the frame (18) relative to the center of gravity of the gate (14). Furthermore, a latch (58) and other features of the hopper (10, 120) control the movement of the gate (14) to regulate the flow of the material (12) from the hopper (10, 120).
