  • Patent number: 4883022
    Abstract: An improved animal waterer which provides a cover having a depending polygonal basin with ports in the sidewalls of the basin. The cover overlies a water container such that the basin engages water in the container. A float which glides vertically along a pair of guides allows an animal to depress the float angularly while preventing removal of the float from the basin. A sloped, ribbed bottom of the container facilitates draining and cleaning of the container.
