ABSTRACT:
The floating skimmer has a body fitted with a floating weir and with a suction outlet in its base for connection to a suction hose. A float is provided to keep the body afloat. The float is hinged to a wall of the body. A scuttle valve is provided in a wall of the body and is connected to the float. If the body should rise in the water, the float drops and opens the scuttle valve to admit water to the body and scuttle it so that it sinks to its former level.
