Abstract
A feeder for discharging a load of material includes a hopper, a swing arm pivoting between raised and lowered positions in the hopper, and a ram mounted on the free end of the swing arm. The ram is moved by the swing arm back and forth on a curved floor in a trapezoidally shaped trough underneath the hopper to push material in the trough out of the hopper through a discharge outlet. A shutoff valve at the discharge outlet prevents backflow of discharged material into the trough.
