Abstract
The hog waterer of this invention includes a center top wall portion with downwardly and oppositely extending wall portions. A pair of lids are pivoted to the center portion for closing an access opening in each of the sloping wall portions. The bottom face of the lid includes a downwardly extending tapered semi-cylindrical closure member which due to a loose pivot connection is self-centering in the access opening. The diameter of the closure member is sufficiently large to space the lid from the sloping top wall portion to prevent any ice build up on the sloping top wall portion from interfering with the closure member from sealing the water in the reservoir tank from the cold outside atmosphere.
