Abstract
Abstract Elongated sections of flexible buoyant tubes are connected together in end-to-end relation for extending offshore along a coastline surrounding an oil tanker or an oil well location. The wall of the tube sections is formed in accordion-pleated fashion for readily conforming to variations in the surface of the supporting water. Anchor means maintains the assembled tubes in approximate location while other means prevents longitudinal expansion of the tubes beyond the yield point of their material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
52 words
A floating boom forming a dam for restricting movement of floating material, said boom, comprising: an elongated resilient buoyant tube having a flexible accordionpleated wall; ballast means maintaining the depending peripheral wall portion of said tube submerged; means limiting longitudinal expansion of said tube; and, anchor means maintaining said tube in place.
Claim 2
Dependent Claim
52 words
A floating boom forming a dam for restricting movement of floating material, said boom, comprising: an elongated resilient buoyant tube having a flexible accordionpleated wall; ballast means maintaining the depending peripheral wall portion of said tube submerged; means limiting longitudinal expansion of said tube; and, anchor means maintaining said tube in place.
Claim 3
Dependent Claim
45 words
Structure as specified in claim 1 in which said elongated tube is formed by a plurality of coaxially aligned tubular sections, and clamp means joining said tubular sections in end overlapping relation and dividing said elongated tube to form a like plurality of closed compartments.
Claim 4
Dependent Claim
20 words
Structure as specified in claim 2 in which said ballast means comprises a quantity of fluid within each closed compartment.
Claim 5
Dependent Claim
61 words
Structure as specified in claim 3 in which said clamp means comprises: a straplike ring within one end portion of each said tubular section; a diaphragm having a flangelike wall interposed between said ring and the inner wall surface of said one end portion of each said tubular section; and, a straplike clamp surrounding overlapped end portions of said tubular sections.
Claim 6
Dependent Claim
66 words
Structure as specified in claim 4 in which the expansion limiting means comprises: a pair of eyebolts having interconnected shank portions extending through and connected with each said diaphragm; and, a like plurality of elongated strands each having a length at least as great as each said tubular section and extending therethrough and connected, at respective ends with said eyebolts on respective sides of said diaphragms.
Claim 7
Dependent Claim
82 words
Structure as specified in claim 1 in which said elongated tube is formed by a plurality of coaxially aligned tubular sections, and further including clamp means joining said tubular sections in end abutted relation, said clamp means comprising: a split ring, U-shaped in cross section, surrounding respective abutted end portions of said tubular sections; a toggle joint connected with the respective end portions of said split ring; and, a reinforcing ring disposed within the respective abutted end portions of said tubular sections.
Claim 8
Dependent Claim
59 words
Structure as specified in claim 6 in which the expansion limiting means comprises: a plurality of elongated flexible strands, each having a length at least as great as the length of each said tubular section and projecting through the interior thereof; and, a plurality of quick connect couplings connected with and joining said strands in end to end relation.
