ABSTRACT:
This disclosure pertains to a float, slideably confined within a tube and buoyantly positioned therealong as determined by the level of the water confined within a container such as a bathtub, swimming pool or the like. The float, upon reaching an upper position, closes a set of stationary contacts, which in turn, completes a series electrical circuit including an alarm bell and battery. Simultaneously with the closing of the contacts, an electrically operated solenoid valve, disposed in series with a pipe communicating to a water source used to fill the container, closes so as to halt any further increase in the water level within the container. Altering the length of the float, or varying the positioning of the contacts relative to the mouth of the container, adjusts the maximum level of water that may be disposed within the container.
