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.
Claims6
A floating skimmer which comprises a body, a floating weir at an edge of the body over which liquid can pass into the body, a suction outlet in the base of the body for connection to a suction hose, at least one float for keeping the body buoyant and which is hinged to the body, a scuttle valve in a wall of the body, and motion transmitting means between the float and the scuttle valve so that as the float pivots downwardly when the body rises in liquid, the scuttle valve is opened to allow liquid to enter the body and cause it to float at its original level.
