Claim 1
Independent Claim
347 words
An improved textile spool which comprises in combination: (a) a hollow tube having a one end and another end, the tube adapted to carry a filament material thereon; (b) a first flange at the one end and a second flange at the other end of the tube; (c) a first axial shaft extending from the one end of the tube and a second axial shaft extending from the other end of the tube; (d) at least one removable plug element which comprises (i) a cylindrical body element having an inner and an outer face and the body adapted to fit in a snug slidable relationship within the inner diameter at the one end of the tube, the first shaft extending centrally and outwardly from the outer face of the body element, and (ii) at least two elongated tongue elements extending generally axially from the inner face of the body element and the tongue elements generally in opposing positions, the tongue elements adapted to yield axially inwardly slightly on the application of a force and tension-biased to return to their original position; (e) discrete raised projection means positioned on the surface toward the extending yieldable end of each of the tongue elements or on the internal wall of the tube; (f) one or more discrete projection-receiving passageway means in the tongue elements or in the wall of the tube; and (g) the projection means and projection-receiving passageway so formed to permit insertion into and removal from the projection-receiving passageway by the respective use of an inward or outward axial force, whereby, in the assembled condition when the body element has been slid into a snug relationship within one end of the hollow tube, the respective discrete projections are engaged in an interlocking relationship within the respective opposite passageway means so that the axial shaft of the plug element may be driven by spool-driving means, and, on the application of an outward axial force, the tension-biased tongue elements yield inwardly to permit the axial removal of the plug element and to place the textile spool in the disassembled condition.
