Abstract
Abstract The disclosure relates to a device for confining pollution material floating on the surface of water to a given area for subsequent collection, storage or other disposition thereof. The device comprises a variable group of individual watertight floatable barrels rising above the water and affording a barrier against the escape of the pollution material from the area, together with universal joints connecting adjacent barrels of the group to one another and serving to allow the individual barrels to pitch and roll in accordance with the pitch and roll of the water upon which the barrels are floated and thus to maintain the barrier operative despite undue water movement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
Fireproof equipment for confining surface pollutants within a predetermined area of water; said equipment comprising an indeterminate number of individual watertight fireproof floatable cylindrical drums of which the opposite ends comprise concave surfaces; each of said drums having the capability of floating with one-third of the diameter thereof submerged and two-thirds of the diameter thereof rising above the surface of water to serve as a barrier against escape of surrounded pollution material, and universal joints between adjacently disposed drums of said indeterminate number of individual drums; said universal joints effectively maintaining the entire group of said drums in upright position despite undue water motion and each comprising two main parts, one of said two main parts being rotatably mounted on one end of each of said drums, and the other of said two main parts is movable within the concave surfaces of an adjacent end of an adjacently disposed drum.
Claim 2
Dependent Claim
150 words
Fireproof equipment for confining surface pollutants within a predetermined area of water; said equipment comprising an indeterminate number of individual watertight fireproof floatable cylindrical drums of which the opposite ends comprise concave surfaces; each of said drums having the capability of floating with one-third of the diameter thereof submerged and two-thirds of the diameter thereof rising above the surface of water to serve as a barrier against escape of surrounded pollution material, and universal joints between adjacently disposed drums of said indeterminate number of individual drums; said universal joints effectively maintaining the entire group of said drums in upright position despite undue water motion and each comprising two main parts, one of said two main parts being rotatably mounted on one end of each of said drums, and the other of said two main parts is movable within the concave surfaces of an adjacent end of an adjacently disposed drum.
Claim 3
Dependent Claim
62 words
Equipment as set forth in claim 1, and a first hinge plate projecting from the free extremity of said one main part of said universal joint, a second hinge plate projecting from an outer extremity of said other of said main parts of said universal joint, and a pintle pin removably connecting said first hinge plate and said second hinge plate together.
Claim 4
Dependent Claim
101 words
Fireproof equipment as set forth in claim 1, and a locking device for securing said other mAin part of said universal joint to an adjacent end of an adjacently disposed drum; said locking device comprising a pair of plates secured to said adjacent end on opposite sides of said second hinge plate of said other main part and having aligned passages therethrough, a bolt extending through said passages and through said hinge plate, a turn-lever on said bolt and a holddown pin seated on said turn-lever of said bolt to prevent movement thereof except by the application of an external force.
Claim 5
Dependent Claim
36 words
Fireproof equipment as set forth in claim 1, and a pair of cables lashed to opposite sides of each of said drums to check thrashing about movements of the drums and relieve stresses on said joints.
Claim 6
Dependent Claim
107 words
In fireproof equipment for confining surface pollution material within a predetermined area of water, a plurality of articulated watertight fireproof drums of which one-third of the diameter thereof is submerged in the water, and a stabilizing fin and keel unit removably attached to the under side of the submerged portion of each of said drums; said stabilizing fin and keel unit being symmetrical in contour and comprising ears of equal dimensions projecting laterally from opposite sides of said unit, and a straight keel merging with said ears through arcuate sections of said unit; said keel being coextensive in length with the length of each of said drums.
Claim 7
Dependent Claim
107 words
In fireproof equipment for confining surface pollution material within a predetermined area of water, a plurality of articulated watertight fireproof drums of which one-third of the diameter thereof is submerged in the water, and a stabilizing fin and keel unit removably attached to the under side of the submerged portion of each of said drums; said stabilizing fin and keel unit being symmetrical in contour and comprising ears of equal dimensions projecting laterally from opposite sides of said unit, and a straight keel merging with said ears through arcuate sections of said unit; said keel being coextensive in length with the length of each of said drums.
