Abstract
Abstract The disclosed multi-line fluid-swivel comprises a drum-like structure with the various lines entering the drum, and being directed to respective apertures in the drum-wall. Each aperture has an individually-associated peripheral rotatable manifold, so that each incoming line has fluid communication with a respective manifold. Each manifold is individual; and may be installed, removed, and repaired without interference of or from the others.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
A multi-line fluid-swivel comprising: A. a drum-structure having a wall and a suitably-apertured base; B. means for bringing said lines through respective apertures of said base into said drum; C. means for bringing the portion of said lines in said drum to individual longitudinally-spaced respective apertures of said wall; D. individual annular manifold means, rotatable with respect to said drum-structure and positioned peripherally on said drumstructure, for mating with respective wall apertures; 1. said manifold means comprising: a. a raceway fixedly-positioned with respect to said wall; b. a torus rotatably mounted on said raceway; c. said torus and raceway being matched; E. means for affixing said raceway to said wall.
Claim 2
Dependent Claim
110 words
A multi-line fluid-swivel comprising: A. a drum-structure having a wall and a suitably-apertured base; B. means for bringing said lines through respective apertures of said base into said drum; C. means for bringing the portion of said lines in said drum to individual longitudinally-spaced respective apertures of said wall; D. individual annular manifold means, rotatable with respect to said drum-structure and positioned peripherally on said drumstructure, for mating with respective wall apertures; 1. said manifold means comprising: a. a raceway fixedly-positioned with respect to said wall; b. a torus rotatably mounted on said raceway; c. said torus and raceway being matched; E. means for affixing said raceway to said wall.
Claim 3
Dependent Claim
81 words
A multi-line fluid-swivel for a plurality of not-necessarily symmetrical arrangement of incoming fluid-carrying lines, comprising: A. at least one drum-structure having a wall and a suitably-apertured base; B. means for bringing said lines through respective apertures of said base into said drum; C. means for bringing said lines to individual longitudinally-spaced respeCtive apertures of said wall; D. individual annular manifold means, rotatable with respect to said drum-structure, and positioned peripherally on the wall of said drum-structure, for mating with respective wall-apertures;
Claim 4
Dependent Claim
81 words
A multi-line fluid-swivel for a plurality of not-necessarily symmetrical arrangement of incoming fluid-carrying lines, comprising: A. at least one drum-structure having a wall and a suitably-apertured base; B. means for bringing said lines through respective apertures of said base into said drum; C. means for bringing said lines to individual longitudinally-spaced respeCtive apertures of said wall; D. individual annular manifold means, rotatable with respect to said drum-structure, and positioned peripherally on the wall of said drum-structure, for mating with respective wall-apertures;
Claim 5
Dependent Claim
169 words
A multi-line swivel comprising: A. a first drum-structure having a cylindrical wall, a first suitably-apertured base-plate and a second suitably-apertured base-plate; B. a second drum-structure having a cylindrical wall, a first suitably-apertured base plate, and a second suitably-apertured base-plate; C. means for bringing said lines through respective apertures of said first base-plate into said first drum; D. means for bringing selected ones of said lines to individual longitudinally-spaced respective apertures in said wall of said first drum; E. means for bringing other selected lines from said first drum, through respective apertures of said second base-plate of said first drum and through respective apertures of said first base-plate of said second drum into said second drum; F. means for bringing given ones of said other selected lines to individual longitudinally-spaced respective apertures in said wall of said second drum; G. a plurality of individual annular manifold means, rotatable with respect to said drum-structures, and positioned peripherally on the external surfaces of said drum-structure walls, for mating with respective said wall-apertures;
Claim 6
Dependent Claim
169 words
A multi-line swivel comprising: A. a first drum-structure having a cylindrical wall, a first suitably-apertured base-plate and a second suitably-apertured base-plate; B. a second drum-structure having a cylindrical wall, a first suitably-apertured base plate, and a second suitably-apertured base-plate; C. means for bringing said lines through respective apertures of said first base-plate into said first drum; D. means for bringing selected ones of said lines to individual longitudinally-spaced respective apertures in said wall of said first drum; E. means for bringing other selected lines from said first drum, through respective apertures of said second base-plate of said first drum and through respective apertures of said first base-plate of said second drum into said second drum; F. means for bringing given ones of said other selected lines to individual longitudinally-spaced respective apertures in said wall of said second drum; G. a plurality of individual annular manifold means, rotatable with respect to said drum-structures, and positioned peripherally on the external surfaces of said drum-structure walls, for mating with respective said wall-apertures;
Claim 7
Dependent Claim
