Abstract
Abstract A buoyant barrier boom which preferably typically comprises a relatively rigid sheet of asbestos rubber of about 10 percent to about 20 percent styrene-butadiene rubber content by weight, having a closed cell sponge attached to both faces of the sheet in a position whereby at least two-thirds of the sheet is below water level when floated in water in an erect position substantially vertical to the surface of the water, the portion of the sheet located substantially below water level being laminated with an additional sheet of the rubber-asbestos material in order to provide any additional weight necessary to maintain the structure in an upright position, and in order possibly to provide additional strength, the sheet additionally having attached to each end of the boom a flexible compressed rubber sheet having about a 60 percent to about 70 percent content of styrene-butadiene rubber, each of the laminated sheets being about one-eight inch thick, the sponge material being partially enclosed by the rubber asbestos sheeting of a minor thickness to protect the sponge against abrasion, an achoring means for restraining the boom in a relatively fixed position in water, and a removable clamp for pinching together two flat and overlapped surfaces of the flexible compressed rubber sheet whereby two or more of the booms may be easily attached in series.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A buoyant barrier boom for retaining oil on wateR comprising a relatively rigid barrier sheet of rubber containing fiber, said barrier sheet having a laminate construction in at least the lower approximate two-thirds portion thereof in the area to be located substantially below the surface of the water to provide additional weight and reinforcement to resist water movement, said barrier sheet having a buoyant closed cell foam body attached to both faces of the barrier sheet, said buoyant closed cell foam body being protected by a strip of rubber sheet containing fiber, said buoyant closed cell foam body being substantially horizontal to the top of the barrier sheet and intermediately located thereon approximately one-third from the top and two-thirds from the bottom of said barrier sheet whereby said barrier sheet will float in water in a substantially erect position substantially vertical to the surface of the water with approximately the upper one-third of the barrier sheet above the surface of the water and approximately two-thirds thereof below the surface of the water.
Claim 2
Dependent Claim
172 words
A buoyant barrier boom for retaining oil on wateR comprising a relatively rigid barrier sheet of rubber containing fiber, said barrier sheet having a laminate construction in at least the lower approximate two-thirds portion thereof in the area to be located substantially below the surface of the water to provide additional weight and reinforcement to resist water movement, said barrier sheet having a buoyant closed cell foam body attached to both faces of the barrier sheet, said buoyant closed cell foam body being protected by a strip of rubber sheet containing fiber, said buoyant closed cell foam body being substantially horizontal to the top of the barrier sheet and intermediately located thereon approximately one-third from the top and two-thirds from the bottom of said barrier sheet whereby said barrier sheet will float in water in a substantially erect position substantially vertical to the surface of the water with approximately the upper one-third of the barrier sheet above the surface of the water and approximately two-thirds thereof below the surface of the water.
Claim 3
Dependent Claim
245 words
A buoyant barrier boom for retaining oil on water comprising a relatively rigid barrier sheet of rubber containing fiber, said barrier sheet having a laminate construction in at least the lower approximate two-thirds portion thereof in the area to be located substantially below the surface of the water to provide additional weight and reinforcement to resist water movement, said barrier sheet having a buoyant closed cell foam body attached to both faces of the barrier sheet substantially horizontal to the top of the barrier sheet and intermediately located thereon approximately one-third from the top and two-thirds from the bottom of said barrier sheet whereby said barrier sheet will float in water in a substantially erect position substantially vertical to the surface of the water with approximately the upper one-third of the barrier sheet above the surface of the water and approximately two-thirds thereof below the surface of the water, a flexible rubber sheet secured to each end of the relatively rigid barrier sheet for attaching one barrier sheet to another barrier sheet in series, said flexible rubber sheet being of approximately the same height as the barrier sheet whereby it extends substantially the same distance above and below the surface of the water, and the said barrier sheet being attached to another like sheet in series by means of a removable clamp comprising hinged levers with fastening means, pinching together overlapping portions of the flexible rubber sheets secured to the ends of the barrier sheets.
Claim 4
Dependent Claim
245 words
A buoyant barrier boom for retaining oil on water comprising a relatively rigid barrier sheet of rubber containing fiber, said barrier sheet having a laminate construction in at least the lower approximate two-thirds portion thereof in the area to be located substantially below the surface of the water to provide additional weight and reinforcement to resist water movement, said barrier sheet having a buoyant closed cell foam body attached to both faces of the barrier sheet substantially horizontal to the top of the barrier sheet and intermediately located thereon approximately one-third from the top and two-thirds from the bottom of said barrier sheet whereby said barrier sheet will float in water in a substantially erect position substantially vertical to the surface of the water with approximately the upper one-third of the barrier sheet above the surface of the water and approximately two-thirds thereof below the surface of the water, a flexible rubber sheet secured to each end of the relatively rigid barrier sheet for attaching one barrier sheet to another barrier sheet in series, said flexible rubber sheet being of approximately the same height as the barrier sheet whereby it extends substantially the same distance above and below the surface of the water, and the said barrier sheet being attached to another like sheet in series by means of a removable clamp comprising hinged levers with fastening means, pinching together overlapping portions of the flexible rubber sheets secured to the ends of the barrier sheets.
