ABSTRACT:
A water supply and control device for animals in which a predetermined amount of water in a water reservoir must be removed before the reservoir is refilled.
The device consists of a water reservoir having a water supply pipe extending into the reservoir with a valve positioned within the pipe and controlling the flow of water through the supply pipe. An upper float assembly has a movable float within the reservoir and is mechanically linked to the valve to open and close it. A lower float assembly has a lower float connected to an arm which is pivotally connected to a fixed location in the reservoir. There is a brace member having one end connected to the arm and the opposite end engaging in restraining relationship the upper float assembly. The brace remains in the restraining relationship with the upper float assembly until the water within the reservoir falls to a predetermined level, with the lower float following the lowering water level until the predetermined level is reached. The brace is then released from the upper float assembly allowing the upper float to drop, opening the valve and allowing a fresh supply of water to enter the reservoir until the upper float assembly shuts off the valve and the brace of the lower float assembly again engages the upper float assembly.
