Patent attributes
A collapsible floating apparatus for controlling a valve includes a floating device and a collapsible lever. The collapsible lever includes a first member rotatably coupled to the valve, and a second member attached to the floating device at one end and rotatably coupled to the first member adjacent another end. The apparatus has a retracted position for shipping and storage, and operational positions. In the position, the second member, or the first and second members together, are brought adjacent to the valve. In operational positions, the first and second members act as a single lever to relay the buoyancy of the floating device drives to the valve. An adjusting member is provided for adjusting a relative position or angle between the first and second members, which in turn adjusts a water level.
