Abstract: The spool holder is provided with a plurality of circular discs of different diameters in which each disc is provided with one or more rows of pins, each pin being of such diameter and length as to extend loosely into the hole formed in a standard type spool. The pins are positioned on the upper surface of each of the discs, and the discs are supported one above the other in a single vertical axis arranged in order of their diameters, the smallest diameter disc being at the top, the disc immediately above a disc carrying more than one row of spool-carrying pins being provided with a single recess extending inwardly from the outer edge of the disc to a point substantially over the pins on the inner row adjacent the outer row of pins.
