Abstract: An animal feeder comprising a circular trough having a raised platform at its center which is positioned directly below the lower end of a vertically disposed feed supply tube. The raised platform includes a first inclined wall which terminates in a substantially vertically disclosed wall portion having a second inclined wall extending downwardly and outwardly from the lower end thereof. A U-shaped water receiving portion is provided at the lower end of the second inclined wall and has an outer side wall extending upwardly therefrom. A moisture sensor is mounted on the second inclined wall above the U-shaped water receiving portion to halt the flow of water to a water nozzle mounted on the second inclined wall, when moisture comes into contact with the moisture sensor. Divider panels are secured to the trough and the feed supply tube to define eating spaces and to import movement to the feed supply tube to prevent bridging of the feed.

Abstract: A hog feeder having dry feed fed by gravity to a trough includes a supply of water thereto. A liquid sensor, relay and solenoid valve are used to maintain the water in the trough at a predetermined level. The liquid sensor used to maintain the liquid level at a predetermined level includes an electrically operated sensor that does not malfunction due to abuse by hogs or due to becoming caked with dirt or feed.
