  • Patent number: 4246678
    Abstract: An animal feeding apparatus for the holding and delivery of feed to animals. The apparatus includes a feed hopper with two inwardly sloping walls and a flow diverter at the bottom of the hopper, splitting and diverting the flow of feed to each of two feeding troughs. The flow diverter extends along the entire length of the feed hopper, being formed by the junction of the rear sloping wall of each feeding trough. The two feeding troughs, extending the entire length of the feeder, are on opposite sides to each other and have a horziontal base portion, a sloping upward rear portion and a sloping upward front portion whose edge is bent back forming a safety edge. Each feeding trough has a plurality of agitators that extend horizontally into the feeding trough and vertically into the feed hopper. The animals through their feeding motion move the agitators which in turn loosen feed in the feed hopper. Individually adjustable feed gates above each agitator control the amount of feed flow.
