Abstract
A spool for filamentary material such as optical fibers and others consists of two members which are locked together to form a drum with two opposed flanges defining a winding space. The two members may be separated to allow material wound on the drum to be removed at will. After the material is removed, the two parts may be locked again making the spool reusable.
Claims4
A spool for producing, holding and transporting fiber optic media, the spool comprising:
- a first member and a second member, said first member and said second member each respectively comprising an inner sleeve, an outer cylindrical wall disposed concentrically about said sleeve, an inner end wall extending from said inner sleeve to said outer cylindrical wall and forming a respective coplanar surface wherein said first member abuts said second member, and an outer end wall formed parallel to said inner end wall and engaging axially outer ends of said outer cylindrical wall, said outer end wall including an annular flange extending radially outward from said outer cylindrical wall;
- a cylindrical sleeve of resilient material removably disposed about said outer cylindrical wall of said first member and said second member;
- a first cap and a second cap for respectively engaging interior radial portions of said first member and said second member, said first cap and said second cap being substantially parallel with said respective annular flanges;
- interlocking means for selectively interlocking said inner end walls of said first member and said second member to define a winding space between said outer end walls of said first member and said second member for holding the fiber optic media, and for disengaging and separating said members to allow at least one portion of the fiber optic media to be removed from the spool, said interlocking means including removable plugs including cam elements for urging said first and second members toward each other when inserted into said interlocking means.
