Abstract
Abstract An adjustable spool comprises a pair of engageable, substantially identical, hermaphroditic components, each component including an end flange axially spaced from the other by an adjustable drum portion. The drum portion is defined by a plurality of axially extending splines projecting from each flange toward the other. The splines are spaced circumferentially about the axis and are arranged to interfit circumferentially in assembly. The splines are provided with a plurality of axially spaced tooth-like engagement elements. Each flange has interposed circumferentially between splines an opening for receipt therein of a free end of a spline and a latching member adjacent each opening for engaging the tooth-like members on the splines.
