ABSTRACT:
A device for cleaning an oil spill from a water surface comprises an inclined rotatably mounted helical screw having a lower water-engaging end and an upper outlet end, a screw casing encasing said screw for rotatably supporting the screw, the screw casing closely encasing the screw so as to form a rotating fluid seal between the casing and the rotatably mounted screw, the screw casing having a lower opening for partial submersion in the water and an upper outlet for the evacuation of the oil from the screw into a storage reservoir. The helical vane of the screw has oil separating perforations therein for retaining the oil on the upper surface of the vane while allowing the water to flow therethrough.
