Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A pipe supply reel for continuous laying of pipelines, comprising in combination with a horizontally disposed base: a. a hollow upwardly and inwardly tapering frustoconical hub mounted on the base for rotation about its vertical axis; b. horizontally disposed upper and lower annular flanges secured respectively about the upper and lower ends of said hub; c. roller means mounted on the base to extend upwardly into rolling supporting engagement with said lower flange; d. pivot means mounted on the base and extending into the bore of the hub into centering engagement with the inner wall of said bore; and e. drive-engaging means circumferentially mounted to said lower flange.
Claim 2
Dependent Claim
108 words
A pipe supply reel for continuous laying of pipelines, comprising in combination with a horizontally disposed base: a. a hollow upwardly and inwardly tapering frustoconical hub mounted on the base for rotation about its vertical axis; b. horizontally disposed upper and lower annular flanges secured respectively about the upper and lower ends of said hub; c. roller means mounted on the base to extend upwardly into rolling supporting engagement with said lower flange; d. pivot means mounted on the base and extending into the bore of the hub into centering engagement with the inner wall of said bore; and e. drive-engaging means circumferentially mounted to said lower flange.
Claim 3
Dependent Claim
31 words
