ABSTRACT:
Oil sweeper method and apparatus including an elongated structural framework adapted to be towed transversely across the surface of water bearing an oil film contaminant, the framework supporting a pair of longitudinally extending, parallel vertical screens, wherein the forwardmost screen relative to the direction of sweeping motion is constituted of multiple panels pivotally attached to the framework for swinging movement about vertical swinging axes, and the rearward screen is water impervious. When the panels of the forwardmost screen are pivoted they define channels therebetween for diverting surface water and floating contamination such as oil in a lateral direction towards a skimmer disposed at one end of the sweeper apparatus. The rearward screen assists in further deflecting the water and oil towards the skimmer after they have traversed the channels between the pivotable panels.
