ABSTRACT:
An apparatus for skimming the surface of body of liquid includes a hollow support member and an tubular collector member having a top opening and vertically slidable in the support member and connected to the suction input of a centrifugal pump. The support member either floats in the liquid body or is supported on the floor of the liquid body and is at a level that, in the dormant condition of the apparatus, the collector member opening is slightly above the liquid surface. Upon actuation of the pump, the suction lowers the collector member and draws the surface water over the edge of the collector member which may be covered by a filter bag for retaining debris.
