Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
In an oil removal apparatus in which an endless mop like structure is floated on the surface of the water in contact with the oil, a buoyant pulley-like support for said mop comprising: a. a substantially U-shaped support frame, b. a buoyant pulley having a buoyant chamber and top and bottom flanges about which the oil mop is adapted to pass, c. spindle means extending off the top and bottom flanges on said buoyant pulley centrally thereof and being journalled for rotational support proximate the free ends of said U-shaped support, d. weight anchoring means connected to one of said U-shaped arms to maintain the pulley in a substantially horizontal floating attitude, and e. a second means connected to said U-shaped member for maintaining an anchor point at an angle to the weight anchoring means to resist pull imposed by the oil mop to keep the buoyant pulley horizontal.
Claim 2
Dependent Claim
149 words
In an oil removal apparatus in which an endless mop like structure is floated on the surface of the water in contact with the oil, a buoyant pulley-like support for said mop comprising: a. a substantially U-shaped support frame, b. a buoyant pulley having a buoyant chamber and top and bottom flanges about which the oil mop is adapted to pass, c. spindle means extending off the top and bottom flanges on said buoyant pulley centrally thereof and being journalled for rotational support proximate the free ends of said U-shaped support, d. weight anchoring means connected to one of said U-shaped arms to maintain the pulley in a substantially horizontal floating attitude, and e. a second means connected to said U-shaped member for maintaining an anchor point at an angle to the weight anchoring means to resist pull imposed by the oil mop to keep the buoyant pulley horizontal.
