  • Patent number: 7059342
    Abstract: An automatic liquid shut-off system for a vessel and having a valve in a liquid passageway to control the level of liquid in the vessel so as to prevent an overflow of the liquid. The shut-off system comprises a conduit extending exterior from one wall of the vessel and in liquid communication therewith. A float is disposed in the conduit, and a stem extends from the float co-axially with the conduit, and is affixed to the valve to actuate the valve to a closed position. When the liquid level in the vessel rises to an undesired level, and the liquid in the vessel therefore reaches a level approximately the level of the float, the liquid acting upon the float will actuate the valve to a closed position, thereby shutting off the liquid.
