ABSTRACT:
The invention improvements are embodied in animal feeding apparatus including a storage tank for liquid and means for a supply of dry feed in overlying vertically spaced relation to a feed tray. The apparatus features improved controls triggered by the animals which feed from the tray. The storage tank for the liquid has a discharge opening in its bottom rimmed by dependent tube structure the lower extremity of which is continuously immersed in the liquid feed provided in the tray. A hollow valve structure is mounted in the tank to normally close and seal its discharge opening. Means in connection with the dependent tube structure trigger an automatic opening of said valve when the mixture in the tray drops to a predetermined level which is above the dependent extremity of the tube structure. The latter means include a small bore vent tube, one end of which is continuously exposed to the atmosphere and the other end of which is located interiorly of the tube structure, adjacent its bottom, and faces upwardly thereof to be in continuous communication with the interior of the valve member, by way of an access opening therein, when the valve is in a closed position. As the valve is displaced from its closed position, it triggers means operative to deliver a measured supply of dry feed to the underlying tray.
