Abstract
A cavity slightly larger and deeper than the bobbin it is adapted to receive is formed in one or both ends of the spool. A pair of diametrically opposing, bobbin-engaging tabs are formed on the cavity-bearing end and extend into the cavity. In addition, a pair of diametrically opposing notches are formed in the cavity-bearing end and open into the cavity so that the operator can reach under an outer portion of the bobbin and pry the bobbin out of the cavity.
