Abstract
Abstract A device that is placed upon a large spool of line or other wound material to control the alignment of the line as it is unwound therefrom comprising a first means defining an aperture through which the unwinding line passes and second means for holding said first aperture loosely adjacent about the outer windings intermediate the ends of the spool to allow it to slip around the spool during unwinding.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
In combination with a spool having strand material wound thereon, a device for retaining the strand material intermediate the ends of the spool during unwinding of the strand material from the spool; said device comprising an element having two spaced apart apertures formed therethrough, each aperture larger than the strand material on said spool; an end of said strand material passing through one of said apertures, around said spool and through the other of said apertures, whereby the strand material extending from the other of said apertures diverges from the strand material extending through said one of said apertures during unwinding to maintain said element loosely adjacent the outer windings of said strand material on said spool and to allow said element to slip around said spool during unwinding.
Claim 2
Dependent Claim
129 words
In combination with a spool having strand material wound thereon, a device for retaining the strand material intermediate the ends of the spool during unwinding of the strand material from the spool; said device comprising an element having two spaced apart apertures formed therethrough, each aperture larger than the strand material on said spool; an end of said strand material passing through one of said apertures, around said spool and through the other of said apertures, whereby the strand material extending from the other of said apertures diverges from the strand material extending through said one of said apertures during unwinding to maintain said element loosely adjacent the outer windings of said strand material on said spool and to allow said element to slip around said spool during unwinding.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein said two, spaced-apart apertures lie in a common plane.
Claim 4
Dependent Claim
66 words
The device of claim 1 wherein said element includes a pair of slots, one extending from each aperture out the side thereof toward an end of the spool, substantially narrower than the strand material on the spool to permit said element to be flexed slightly and the said slots opened so that the strand material may be passed from outside said element into the respective apertures.
Claim 5
Dependent Claim
30 words
The device of claim 1 including a handle extending outward from said element to aid in holding and controlling said element when rewinding unused strand material back on the spool.
