  • Animal feeder with multiple adjustable feed volume flow control means
    Patent number: 5245949
    Abstract: This invention is a free choice feeder for livestock and other uses with a special micro feed control. This is a self feeder which comprises a base pan and a hopper positioned above. The base pan contains a rotary feed control wheel with attached feeder rods which allows feed to flow from the hopper into the base pan. The flow of material is determined by a crank screw and locking nut to provide a continuous, non interrupted flow of feed or other material from the hopper into the base pan. The hopper and base pan is held together in a rigid position by the use of a grill work consisting of top and bottom ring and numerous grill vertical dividers.
