Spool holder for transferring line

A spool holder for holding a spool having a central bore to transfer a quantity of line between the spool and a reel comprising:

• a generally U-shaped member having a horizontal bottom wall with an underside, first and second vertical side walls fixed in laterally spaced relation, a horizontal portion at an upper end of said first vertical side wall extending perpendicular thereto;
• suction cup mounting means on the underside of said horizontal bottom wall for releasably securing said U-shaped member to a support surface;
• a first circular aperture extending through said first vertical wall a distance downwardly from said upper end, a second circular aperture extending through said second vertical side wall a distance downwardly from an upper end thereof in horizontal axial alignment with said first circular aperture, an open ended vertical slot extending downwardly from said second vertical side wall upper end and terminating in said second circular aperture, and a threaded bore extending vertically through said horizontal portion with its axis perpendicular to the horizontal axis of said circular apertures;
• a shaft having a central portion adapted to be received through said spool central bore and frictionally engaged therein to prevent relative rotation between said shaft and said central bore and having first and second reduced diameter outer ends;
• said first reduced diameter end extending rotatably through said first circular aperture and axially outward from said first vertical side wall to rotate relative thereto and said second reduced diameter end being pressed downwardly through said slot and received in said second circular aperture to extend rotatably therethrough and axially outward from said second vertical side wall to rotate relative thereto such that said spool and said shaft rotate as a single unit relative to said vertical side walls;
• a hand crank operatively connected to said second reduced diameter end of said shaft to rotate said spool and said shaft as a single unit;
• and
• an adjustable thumb screw having a threaded shaft threadedly engaged in said threaded bore to extend vertically through said horizontal portion of said first side wall and a bottom end selectively movable into engagement with said first reduced diameter end of said shaft to apply an adjustable amount of frictional resistance to said shaft during rotation to maintain tension in said line when being unwound from said spool and transferred onto the reel, and being movable out of engagement with said first reduced diameter end to allow free rotation of said shaft and said spool when said line is being unwound from the reel and transferred onto said spool.
