Abstract
Abstract A spool for wire and like products, comprising a generally cylindrical body portion so arranged that the spool separates into two substantially identical halves along a transverse plane which is perpendicular to the spool axis and is located preferably substantially intermediate the ends of the body portion. The joining or engaging parts of the body portion are keyed to each other against turning and are prevented from separation by novel means arranged so that the securement or clamping action thereof is enhanced by the force exerted by the wire or similar material which is wound on the spool. In the main embodiment of the invention the body halves have quarter-segment splined portions and quarter-segment keyways receiving the spline portions, all said spline portions having circumferential clamping grooves which become aligned to constitute a single annular groove which is completely filled by the beginning turns of the wire which is wound on the body portion. The beginning turns thus lock the body portions to each other.
