  • Poultry feeder with adjustable feed level control
    Patent number: 6050220
    Abstract: A poultry feeder includes a drop tube which attaches to a horizontal feed distribution line, and a feed pan and grill assembly is mounted on the drop tube for vertical sliding movement. An annular flow control member is supported above the feed pan for relative vertical movement by an actuator sleeve and a set of racks and pinions to produce downward movement of the flow control member in response to upward movement of the drop tube with the feed distribution line. The flow control member may also be adjusted manually relative to the drop tube for selecting the maximum level of feed in the feed pan.
