Abstract
Abstract The interior passageway formed at the central axis of a bundle of at least three cylindrical elements which are drawn together within a contractable outer member serves to maintain the ends of optical fibers or the like in accurate axial alignment to provide a splice joint or connection thereat.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
A method of maintaining selective portions of two elongate members in axial alignment with one another comprising the steps of: (a) disposing the ends of said elongate members in end-to-end facing disposition adjacent one another within the axial center of a bundle of at least three elongate cylindrical elements each having a uniform outer diameter; (b) disposing a contractable member about said bundle; (c) radially contracting said contractable member about said bundle so as to cause said cylindrical elements to be displaced inwardly in tangential contacting engagement with said elongate members; (d) transversely dividing one of said cylindrical elements into two parts spaced from one another; and (e) providing an opening in said contractable member coincident with the spacing between said two parts of said cylindrical element, for observing the disposition of said elongate members within said bundle.
Claim 2
Independent Claim
138 words
A method of maintaining selective portions of two elongate members in axial alignment with one another comprising the steps of: (a) disposing the ends of said elongate members in end-to-end facing disposition adjacent one another within the axial center of a bundle of at least three elongate cylindrical elements each having a uniform outer diameter; (b) disposing a contractable member about said bundle; (c) radially contracting said contractable member about said bundle so as to cause said cylindrical elements to be displaced inwardly in tangential contacting engagement with said elongate members; (d) transversely dividing one of said cylindrical elements into two parts spaced from one another; and (e) providing an opening in said contractable member coincident with the spacing between said two parts of said cylindrical element, for observing the disposition of said elongate members within said bundle.
Claim 3
Dependent Claim
26 words
The method as defined in claim 1 wherein said contractable member is contracted by heating, said contractable member comprising a given length of heat shrinkable tubing.
Claim 4
Dependent Claim
29 words
The method as defined in claim 1 further comprising the step of disposing the ends of said elongate members in abutting relationship within the axial center of said bundle.
Claim 5
Independent Claim
123 words
A method of splicing optical fibers comprising the steps of: disposing the ends of said optical fibers in abutting end-to-end facing disposition within the axial center of a bundle of at least three elongate hollow cylindrical elements each having a uniform outer diameter; disposing a contractable member about said bundle; radially contracting said contractable member about said bundle so as to cause said cylindrical elements to be displaced inwardly in tangentail contacting engagement with said optical fibers; transversely dividing one of said cylindrical elements into two parts spaced from one another; and providing an opening in said contractable member coincident with the spacing between said two parts of said divided cylindrical element, for observing the disposition of said optical fibers within said bundle.
Claim 6
Independent Claim
123 words
A method of splicing optical fibers comprising the steps of: disposing the ends of said optical fibers in abutting end-to-end facing disposition within the axial center of a bundle of at least three elongate hollow cylindrical elements each having a uniform outer diameter; disposing a contractable member about said bundle; radially contracting said contractable member about said bundle so as to cause said cylindrical elements to be displaced inwardly in tangentail contacting engagement with said optical fibers; transversely dividing one of said cylindrical elements into two parts spaced from one another; and providing an opening in said contractable member coincident with the spacing between said two parts of said divided cylindrical element, for observing the disposition of said optical fibers within said bundle.
Claim 7
Dependent Claim
30 words
The method as defined in claim 4 further comprising the step of tapering the ends of said cylindrical elements to facilitate the insertion of said optical fibers within said bundle.
Claim 8
Dependent Claim
27 words
The method as defined in claim 4 further comprising the step of shortening one of said cylindrical elements to provide a guide trough for said optical fibers.
Claim 9
Dependent Claim
26 words
The method as defined in claim 4 wherein said contractable member is contracted by heating, said contractable member comprising a given length of heat shrinkable tubing.
