ABSTRACT:
A freeze-proof livestock watering device comprising an open-topped drinking reservoir having insulated side walls and a heat conductive bottom panel constructed and arranged to produce a very low-cost operation by incorporating a combination of low-volume turbulence-producing jets and apparatus for providing a heat transfer relationship between the bottom of the drinking reservoir and the above-freezing, sub-frost level ground temperatures. A float valve is also provided to maintain a minimum water level while the livestock are drinking from the pan, and an overflow drain is provided to maintain a maximum water level during inactive periods of use. A thermostatic control valve may be provided to control the discharge of water through the jets in accordance with the water temperature in the pan, and a protective hood is provided over the float valve and drain outlet to prevent freezing thereof.
A new method is also provided for supplying water for livestock in a manner which prevents freezing thereof and includes discharging turbulence-producing water through discharge jets into a drinking reservoir simultaneously with transmitting above-freezing, sub-frost level ground temperature air into heat conductive contact with a portion of the water reservoir while maintaining a minimum water level within the drinking reservoir during usage.
