  • Livestock waterer
    Patent number: 7975649
    Abstract: A livestock waterer for use in frigid climates includes a lid which floats on the surface of the water in each basin of the waterer. The lid is hollow with a convex upper surface and with baffle walls depending from the underside of the lid. The baffle walls interrupt wave action on the surface of the water created by depression of the lid into the water when an animal presses down on the lid to gain access to the water. The floor of each basin is provided with an integrally formed mounting post to support a heater within the basin. The baffles walls prevent exhaustion of water within the basin thereby preserving submersion of the heater at all times.
