Abstract
Abstract Apparatus for gathering and cleaning water surfaces of pollution, debris, and the like, which comprises an elongated floating boom structure which protectively supports a flexible curtain having float means secured along an upper edge and weight means along a submerged edge, the float means and weight means being connected by slack chains to adjacent portions of the floating boom structure so as to maintain the curtain in an effective operating and working position, and wherein the boom structure mounts protective shielding screens for the curtain, and additionally includes upstanding baffles connectable with float means and/or the floating boom structure. In a modified arrangement, pairs of boom structures support a common curtain therebetween, the curtain being secured along its side edges and being downwardly curved to provide an elongate trough or sluice.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
Apparatus for gathering and cleaning water surfaces of pollution, comprising: a. a continuous elongated flexible curtain having longitudinal opposite side edges; b. float means secured to and extending along one of said side edges; c. weight means secured to and extending along the other of said side edges, said float means and weight means coacting to position said curtain in a generally upright position extending below the surface of the water; and d. a plurality of cradle frame assemblies connected in end-toend relation along said curtain, said cradles having boom float members positioned on opposite sides of said float means; and e. flexible connections between said float means and said weight means, respectively, and parts of said cradle assemblies for maintaining said curtain in a position between the boom float members of said cradle assemblies.
