Abstract: An apparatus for watering animals having an enclosed housing with a reservoir of water disposed therein. A cup-shaped member is disposed on an upward part of such housing for receiving the mouth of an animal to be watered, and an opening is disposed in the cup-shaped member which has a draw tube attached thereto. The draw tube extends from such opening down into the water in the reservoir for permitting an animal having its mouth in such cup-shaped member to suck water from the reservoir, through the draw tube and through the opening and into its mouth, whereby the water in the reservoir will constantly be made available for drinking, but will be isolated from outside ambient temperatures and dirt.

Abstract: This invention relates to freeze protected livestock watering assemblies in general, and more specifically to a watering device, which incorporates a dual activated variable flow water supply valve structure, which is operatively connected to an apertured float arm to progressively increase the volume of water supplied to a drinking receptacle in proportion to the degree of depression of the float arm actuator.
