Abstract
Abstract A conveyer arrangement adapted to be used onto a barge or similar boat in combination therewith and including two superjacent endless-belt conveyers arranged to cooperatively pick up a floating pollutant, such as oil, and to convey the same upwardly between adjacent runs of the respective conveyers which are driven at substantially the same linear speed. Transverse ribs are secured to the top endless-belt conveyer and extend therefrom into liquid-tight edgewise engagement with the top run of the bottom endless belt in cooperation with longitudinally extending flexible wings arranged to laterally confine the picked-up pollutant and water during upward displacement thereof intermediate the two adjacent runs. The conveyers are pivoted onto the bow and the barge is provided with water ballast tanks to adjust the dipping depth of the outer end of the conveyers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
221 words
An apparatus for removing oil and other solid debris floating on water, comprising, in combination, a bottom conveyer means constructed and arranged to be supported onto the bow of a barge to protrude downwardly and forwardly therefrom, a top conveyor means mounted superjacent to said bottom conveyor means and in cooperation therewith, said top and bottom conveyor means each including an imperforate flexible endless belt, the adjacent runs of said top and bottom conveyor belts being flat surfaces longitudinally and transversely of said belts, pocket forming means fixed to said top conveyor belt to travel therewith and arranged to operatively engage the outer surface of the bottom conveyor belt, drive means to drive said bottom and top conveyor belts at equal linear speeds, with the adjacent runs moving in the same direction from the water into said barge, said pocket forming means including longitudinally spaced vanes extending transversely of the top cOnveyor belt and wings merging with and extending from each end of the respective vanes longitudinally of said top conveyor belt, said vanes and wings protruding from the outer surface of the top conveyor belt and having a substantially uniform depth forming a continuous straight edge for liquid-tight contact with the outer surface of the top run of the bottom conveyor belt to form a series of liquid retaining pockets.
Claim 2
Independent Claim
221 words
An apparatus for removing oil and other solid debris floating on water, comprising, in combination, a bottom conveyer means constructed and arranged to be supported onto the bow of a barge to protrude downwardly and forwardly therefrom, a top conveyor means mounted superjacent to said bottom conveyor means and in cooperation therewith, said top and bottom conveyor means each including an imperforate flexible endless belt, the adjacent runs of said top and bottom conveyor belts being flat surfaces longitudinally and transversely of said belts, pocket forming means fixed to said top conveyor belt to travel therewith and arranged to operatively engage the outer surface of the bottom conveyor belt, drive means to drive said bottom and top conveyor belts at equal linear speeds, with the adjacent runs moving in the same direction from the water into said barge, said pocket forming means including longitudinally spaced vanes extending transversely of the top cOnveyor belt and wings merging with and extending from each end of the respective vanes longitudinally of said top conveyor belt, said vanes and wings protruding from the outer surface of the top conveyor belt and having a substantially uniform depth forming a continuous straight edge for liquid-tight contact with the outer surface of the top run of the bottom conveyor belt to form a series of liquid retaining pockets.
Claim 3
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said wings terminate short of an adjacent transverse vane and are made of flexible material to flex longitudinally and follow the travel and longitudinal bending of the top conveyor belt.
Claim 4
Dependent Claim
68 words
An apparatus as claimed in claim 1, wherein each conveyor means includes a frame for mounting the conveyor belt, extensible means interconnecting the respective frames, and power means to extend said extensible means to move the bottom run of said top conveyor belt away from the top run of said bottom conveyor belt to allow use of said bottom conveyor belt only for the collection of solid debris.
