Abstract
A device for automatically controlling the water level in a basin, such as a bathtub. Air pressure in a tube is used to halt water flow into the basin when a desired water level is reached. Various water levels can be selected by opening pressure relief openings in the tube.
Claims10
A device dependent upon the water level in a basin for automatically controlling the flow of water into the basin, comprising
- (a) a water inlet into the basin,
- (b) a valve in said inlet having two orientations, a first orientation permitting flow of water from said inlet into said basin and a second orientation preventing flow of water from said inlet into said basin,
- (c) a valve operator associated with said valve, said valve operator including a regulator having a flexible diaphragm, and including a linkage extending from said diaphragm and connected to said valve for operating said valve,
- (e) an elongated air pressure tube located in the basin and disposed vertically, said tube having an open bottom and including at least one pressure relief opening in the length thereof for permitting selection of different water levels in the basin,
- (f) means extending between said tube and said regulator for communicating air pressure from said tube to said regulator.

A device dependent upon the water level in a basin for automatically controlling the flow of water from a faucet into the basin, comprising
- (a) a valve in the faucet having two orientations, a first orientation permitting flow of water from said faucet into said basin and a second orientation preventing flow of water from said faucet into said basin after a predetermined water level is attained in said basin,
- (b) a valve operator attached to said valve, said valve operator including a regulator having a flexible diaphragm disposed within a housing, and including a linkage secured to and extending from said diaphragm and connected to said valve for operating said valve,
- (c) an elongated air pressure tube located in the basin and disposed vertically, said tube having a plurality of pressure relief openings spaced vertically from one another for permitting selection of different water levels in the basin,
- (d) a removable plug for closing each pressure relief to prevent escape of air therefrom, and
- (e) a sealed conduit extending between said tube and said regulator for communicating air pressure from said tube to said regulator.
