Abstract:
1. A revolving rack for chain spools, comprising: a frame having an operative section and a fixation section; a rotating mechanism connected to the operative section, the rotating mechanism including two pairs of sprockets, each pair of sprockets mechanically connected by a drive chain, and a drive shaft for coupling one sprocket in each of the pair of sprockets; a plurality of spool holders removably and pivotally connected to the rotating mechanism by a fixation pin inserted through an aperture formed in each of a pair of aligned plates that define one link in the drive chain, the aperture disposed between a pair of pins connected to said one link and that connect said one link to adjacent links in the drive chain, each of the plurality of spool holders including a pivot for pivotally holding a spool for relative movement between the pivot and the spool and a cradle holder extending from the pivot to prevent external contact with the spool, wherein the spool includes a wound length of chain and the pivot includes a pair of intersecting planar walls disposed normal to one another; a central support fixed to a central opening in the spool such that the central support and the spool rotate synchronously without relative movement therebetween, the central support including rotating ends that facilitate relative movement between the central support and the rotating ends, the rotating ends including a pair of intersecting planar sides disposed normal to one another and placed within the pivot so that each of the pair of intersecting planar sides engage one of the pair of intersecting planar walls such that the central support rotates relative to the rotating ends and the pivot; and a drive connected to the rotating mechanism for moving the plurality of spool holders from an inoperative position to an operative position.
