Abstract
An automatic oil-water separating device used within an oil-water separating container for skimming the oil off the top of the water and directing same through a collecting conduit to an associated container. The device includes a skimming trough supported by first floatation means mounted on opposite sides of the trough, and a second floatation means transversely disposed to the trough. The specific shape of both the first and second floatation means is designed to immediately restore the trough to the skimming position in the event the unit is accidentally submerged below the surface of the water and to automatically pivot the unit to accelerate oil separation.
