ABSTRACT:
An apparatus for recovering fluid substances floating on a water surface or the like, and consisting of two symmetrical floating bodies connected by means of walls which form between them a longitudinal channel which is closed at its rear end by a transversal wall. The apparatus has a bottom wall which, beginning from a front weir sill positioned near the waterline, at first descends with a small slope and then slopes down rapidly so as to form the bottom of a calm basin which also extends backwardly beyond the floating bodies, said weir sill being wider than the distance between the outer side walls of the floating bodies. A chamber is provided behind the rear wall of the basin and communicates with the basin, through an orifice arranged in the wall near the bottom. The chamber also communicates with a conduit in which is mounted a propeller which rotates at an adjustable speed. Downstream of the propeller the conduit communicates with an outlet conduit, the outlet orifice of which is positioned always underneath the free water surface. Inside of the basin an apparatus for the collection and the removal of the oil is mounted.
