Abstract
Abstract An apparatus for removing oil slicks from the surface of the water which includes two independently pivotable booms connected together to form a V. A paddle wheel is connected to the two booms across the open end of the V for skimming the oil off the surface of the water and forcing the oil towards the apex of the V. A sump is located at the apex of the V for collecting the oil forced to the apex of the V by the paddle wheel. A flexible stabilizer bar is connected between the two booms for stabilizing the booms and limiting the maximum amount that the booms may pivot with respect to each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
An apparatus for collecting oil from the surface of a body of water, said apparatus comprising: two flotatable booms, each boom having a first end and a second end, means connecting the first ends of said booms together for pivoting independently about a horizontal axis and defining the apex of a V-shaped structure, said second ends of said flotatable booms being spaced apart to dEfine the open end of a V-shaped structure, paddle means mounted on a shaft, said shaft including telescoping means permitting the shaft to vary in length, pillow block means mounting the ends of said shaft to said second ends of the respective flotatable booms to permit the ends of said shaft to vary their angular position independently relative to the second ends of said booms, drive means for driving said paddle means about said shaft axis, collection means positioned generally at the apex of the Vshaped structure for collecting the oil forced by the paddle means toward the apex of the V for removing the oil from the surface of the body of water, and means for restraining lateral movement between the spaced second ends of said flotatable booms and for restraining relative movement of said booms about said horizontal pivot axis.
Claim 2
Independent Claim
206 words
An apparatus for collecting oil from the surface of a body of water, said apparatus comprising: two flotatable booms, each boom having a first end and a second end, means connecting the first ends of said booms together for pivoting independently about a horizontal axis and defining the apex of a V-shaped structure, said second ends of said flotatable booms being spaced apart to dEfine the open end of a V-shaped structure, paddle means mounted on a shaft, said shaft including telescoping means permitting the shaft to vary in length, pillow block means mounting the ends of said shaft to said second ends of the respective flotatable booms to permit the ends of said shaft to vary their angular position independently relative to the second ends of said booms, drive means for driving said paddle means about said shaft axis, collection means positioned generally at the apex of the Vshaped structure for collecting the oil forced by the paddle means toward the apex of the V for removing the oil from the surface of the body of water, and means for restraining lateral movement between the spaced second ends of said flotatable booms and for restraining relative movement of said booms about said horizontal pivot axis.
Claim 3
Dependent Claim
35 words
The apparatus as set forth in claim 1, wherein said restraining means includes a telescoping bar having one end coupled to said first boom means and the other end coupled to said second boom means.
Claim 4
Dependent Claim
30 words
The apparatus as set forth in claim 1, wherein said paddle means comprises: a paddle wheel including a plurality of blades mounted on said shaft and extending radially outwardly therefrom.
Claim 5
Dependent Claim
45 words
The apparatus as set forth in claim 1, wherein said drive means comprises: a. a motor mounted on one of said boom means; b. a gear means operatively connected to said paddle means; and c. chain means coupling said motor means to said gear means.
Claim 6
Dependent Claim
67 words
The apparatus as set forth in claim 1, wherein said collection means comprises an oil skimmer positioned between said flotatable booms and between said first ends of said boom means and said paddle means, said skimmer being floatable and further including flexible means for attaching said skimmer to both booms to limit movement of said skimmer on said water relative to said booms on either side thereof.
