ABSTRACT:
A watering device for animals includes a cylindrical container with an open top and surrounding lip around the open top. A closure member for the open top includes a disc which is flat with a surrounding skirt extending along the sides of the container. The skirt has holes to allow the escape of air trapped under the closure member. The closure member carries a downwardly extending guide member on the under surface which carries a float and which is guided for movement in a vertical direction. The float is located under the water surface so that depression of the closure member and the float do not significantly alter the water depth. The float keeps the closure member up against the lip thus fully closing the container. The animal depresses the closure to a level under the water surface to access the water for drinking. If the water level falls, the downward pressure for the animal to access the water engages a valve to refill the container. The natural tendency of the animal is to maintain the water level at a required level below the top. This arrangement reduces the tendency of the animal to spoil or spill the water.
