ABSTRACT:
Apparatus for skimming matter such as oil, scum, and the like floating on water in rivers, lakes, oceans, water-tanks, settling-tanks. The apparatus is adapted to float on the water and comprises a vessel having a main floatable body with at least one inlet opening provided in the sidewall thereof and with matter storage container means in fluid communication with the sidewall inlet opening. A floatable gate means is provided externallly on each sidewall inlet opening of the main body in slidably supported relationship to the latter and is adapted to float on the surface of the body of water outside the main floatable body. Each gate means includes a vertical gate plate externally disposed slidably on the inlet opening sidewall of the main floatable body, the gate plate having an inlet opening therein adapted to be at least partially aligned with the corresponding sidewall inlet opening, at which time only, the floating matter can enter the main floatable body through the at least partially aligned openings. The gate means further includes a float block at each side end of the gate plate whereby the opening in the gate plate over the sidewall inlet opening is maintained at a substantially fixed level relative to the surface, if changing, of a body of water on which the matter floats. Means for setting the lower edge of the inlet opening in the gate plate is adjustably mounted on the gate plate. Discharging means such as a pump may be provided either on the main body or on land separate from the apparatus in order to discharge the matter stored in the storage means to a suitable separate place. In a second embodiment of the invention, at least one water jet nozzle is movably placed about the main body for moving the oil, scum, etc., toward the main body.
