Abstract
A spool holder for a sewing machine, which holder finds particular use in a serger-style sewing machine, nests in the core of a thread spool and is matable with a spindle to generally maintain the thread spool in a stationary position for unwinding of the thread wound on the spool during a sewing operation, which spool holder may rotate on the spindle from the application of undue forces but is stable and strong enough to provide stability to the thread spool and its core.
Claims8
In a serger-style sewing maching, means for holding (10) a thread-spool (36) on an upstanding spool support spindle (33) of said serger-style sewing machine, said thread-spool (36) having a hollow core (38) with an inner surface (38a) and an outer surface (38b) with a thread (35) wound on said outer surface (38b), said means for holding (10) comprising:
- an outer member (43) having an internal surface (10i), an external surface (10e), a top end (10t) and a bottom end (10b), said outer member (43) configured to allow said external surface (10e) to mate with said hollow core (38),
- an inner cylindrical hub (39) having a hub wall (39a) and a central longitudinal axis (42), said hub wall (39a) having an interior surface (41a) and an exterior surface (41b) and defining a central bore (41) extending through said hub (39) along longitudinal axis (42),
- a plurality of partition walls (45) axially extending between said top end (10t) and said bottom end (10b), which partition walls (45) communicate between said hub exterior surface (41b) and said outer member inner surface (10i) to generally define a spoke pattern, said spoke pattern coupling said outer member (43) to said inner hub (39);
- said central bore (41) extending between said top end (10t) and said bottom end (10b),
- said thread-spool core (38) mated with said means for holding (10) to engage said hollow core (38);
- said central bore (41) matable with said spindle (33) and operable to maintain said means for holding (10) and said engaged core (38) at a generally nonrotating and stationary position on said spindle (33) during operation of said serger-style sewing machine and unraveling of said thread (35) from said core (38).
