Abstract
Abstract Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure, for example a dock. The apparatus allows lateral and vertical displacement of the boom with changes of wind, current, or tide while maintaining the seal. A deformable, resilient wall held in pressure contact with the dock while supported on a vertically and laterally movable frame displaceable along a vertical pipe spaced from the dock maintains the seal to prevent oil or other pollutants on the surface of the liquid from passing between the end of the boom and the dock.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure comprising: a fixedly positioned approximately vertical elongated member spaced from the fixed structure; means for supporting the boom, said supporting means being displaceable approximately vertically along said elongated member and displaceable angularly of said elongated member; resilient means between said elongated member and the fixed structure and attached to said boom-supporting means and extending along the approximately vertical dimension of the boom, said resilient means comprising a resilient wall which surrounds said elongated member and is movable approximately vertically and is rotatable around said elongated member in pressure contact with the fixed structure; and rigid means attached to said boom-supporting means for pressing said resilient means against the fixed structure to form a surface contact therebetween under pressure deforming said resilient means to conform with the surface of the fixed structure, said resilient means forming an approximately vertically displaceable seal between the boom and the fixed structure, the seal being effective over a range of angular positions of said boom-supporting means and the boom.
Claim 2
Dependent Claim
195 words
Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure comprising: a fixedly positioned approximately vertical elongated member spaced from the fixed structure; means for supporting the boom, said supporting means being displaceable approximately vertically along said elongated member and displaceable angularly of said elongated member; resilient means between said elongated member and the fixed structure and attached to said boom-supporting means and extending along the approximately vertical dimension of the boom, said resilient means comprising a resilient wall which surrounds said elongated member and is movable approximately vertically and is rotatable around said elongated member in pressure contact with the fixed structure; and rigid means attached to said boom-supporting means for pressing said resilient means against the fixed structure to form a surface contact therebetween under pressure deforming said resilient means to conform with the surface of the fixed structure, said resilient means forming an approximately vertically displaceable seal between the boom and the fixed structure, the seal being effective over a range of angular positions of said boom-supporting means and the boom.
Claim 3
Dependent Claim
69 words
Apparatus in accordance with claim 1 in which said elongated member has a substantially cylindrical surface and in which said boom-supporting means includes a frame having rollers mounted thereon and rotatable along said cylindrical surface of said member for moving said boom-supporting means approximately vertically along said cylindrical surface of said member, said rollers being slidable around said cylindrical surface of said member for moving said boom-supporting means angularly.
Claim 4
Dependent Claim
43 words
Apparatus in accordance with claim 1 in which said resilient wall is of approximately circular cross-sectional shape in regions out of contact with the fixed structure and is of flattened cross-sectional shape in the region deformed by pressure contact with the fixed structure.
Claim 5
Dependent Claim
15 words
Apparatus in accordance with claim 1 in which said resilient means is of plastic material.
Claim 6
Dependent Claim
287 words
Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure comprising: a fixedly positioned approximately vertical elongated member spaced from the fixed structure; means for supporting the boom, said supporting means being diSplaceable approximately vertically along said elongated member and displaceable angularly of said elongated member; a resilient wall between said elongated member and the fixed structure and attached to said boom-supporting means and surrounding said elongated member and extending along the approximately vertical dimension of the boom and movable approximately vertically and rotatable around said elongated member; and rigid means attached to said boom-supporting means for pressing said resilient wall against the fixed structure to form a surface contact therebetween under pressure deforming said resilient wall to conform with the surface of the fixed structure, said resilient wall being of approximately circular cross-section in regions out of contact with the fixed structure and being of flattened cross-sectional shape in the region deformed by pressure contact with the fixed structure, the wall regions of approximately circular cross-sectional shape when out of contact with the fixed structure becoming flattened when moved into pressure contact with the fixed structure upon angular displacement of said boom-supporting means and the wall region of flattened cross-sectional shape when deformed by pressure contact with the fixed structure becoming of approximately circular cross-sectional shape when moved out of contact with the fixed structure upon angular displacement of said boom-supporting means, said resilient wall forming an approximately vertically displaceable seal between the boom and the fixed structure, the seal being effective over a range of angular positions of said boom-supporting means and the boom.
Claim 7
Dependent Claim
287 words
Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure comprising: a fixedly positioned approximately vertical elongated member spaced from the fixed structure; means for supporting the boom, said supporting means being diSplaceable approximately vertically along said elongated member and displaceable angularly of said elongated member; a resilient wall between said elongated member and the fixed structure and attached to said boom-supporting means and surrounding said elongated member and extending along the approximately vertical dimension of the boom and movable approximately vertically and rotatable around said elongated member; and rigid means attached to said boom-supporting means for pressing said resilient wall against the fixed structure to form a surface contact therebetween under pressure deforming said resilient wall to conform with the surface of the fixed structure, said resilient wall being of approximately circular cross-section in regions out of contact with the fixed structure and being of flattened cross-sectional shape in the region deformed by pressure contact with the fixed structure, the wall regions of approximately circular cross-sectional shape when out of contact with the fixed structure becoming flattened when moved into pressure contact with the fixed structure upon angular displacement of said boom-supporting means and the wall region of flattened cross-sectional shape when deformed by pressure contact with the fixed structure becoming of approximately circular cross-sectional shape when moved out of contact with the fixed structure upon angular displacement of said boom-supporting means, said resilient wall forming an approximately vertically displaceable seal between the boom and the fixed structure, the seal being effective over a range of angular positions of said boom-supporting means and the boom.
