Abstract
A spool weight comprising a metal weight member which is secured to an upper surface of a spool by means of a double sided adhesive disc, the metal weight member and the adhesive disc having apertures therein which are in alignment with the elongated aperture of the thread spool.
Claims2
A thread spool arrangement comprising:
- A lightweight thread spool with an elongated extending therethrough, said thread spool being adapted to rotate about the longitudinal axis of said elongated aperture to tangentially pay out thread, said thread spool having substantially flat end surfaces lying in a plane substantially perpendicular to said elongated aperture, said end surfaces each having a substantially round periphery;
- A substantially flat metal weight member having a central opening, said weight member having a size which is not greater than the size of said substantially flat end surfaces of said thread spool;
- and
- A sheet of material having opposing adhesive surfaces for securing said metal weight member to one of said end surfaces of said thread spool with the opening of said weight member in registration with said elongated aperture of said thread spool, said sheet having an opening through a central portion thereof which is adapted to be in registration with both said elongated aperture of said thread spool and said opening of said weight member;
- Whereby said weight member prevents said thread spool from rising when paying out thread, and further prevents said thread spool from spilling out thread due to continued rotation of said thread spool when paying out of said thread is stopped.
