Abstract
An apparatus for recovering oil has a bucket for skimming and collecting water and oil floating on the surface of the water. The bucket has a base plate having apertures for draining water collected by the bucket. The apertures have a preselected diameter and length to allow separation of the oil and water utilizing differences in specific gravities and viscosities of the oil and water so that the oil can be discharged from the bucket into an oil recovery tank after the water drains out of the bucket through the apertures but before the oil begins to drain out of the apertures.
