Abstract:

The invention is a perpetual skimming device for insertion into a reservoir containing liquid at the liquid level which allows the top liquid layer to enter an outer cylinder of the device through longitudinal slots, raising a floating inner cylindrical portion, which in turn, shuts off the liquid entry once enough liquid has entered the device to raise the float to cut off the liquid intrusion. The liquid is then removed by a centrally affixed pickup tube having fluid entry ports at the bottom of the tube, located near the base of the outer cylinder. As the liquid is removed, the inner cylindrical float lowers and allows more liquid into the invention, for a perpetual cyclic skimming operation.
