Abstract
A spool for thread with a self contained bobbin holder. A contrivance consisting of a spool with a self contained bobbin holder is described. The invention is based on the fact that the core of the spool is projected beyond the edge of the spool creating a protuberance which functions as a receptacle for the bobbin, allowing the contrivance to temporarily store the mated spool and bobbin for quick and easy retrieval.
Claims5
A thread spool with a spool or bobbin holder, said thread spool comprising an elongated body portion, a hollow cylindrical core open at both ends and extending through the body portion, and a hollow conical protuberance extending from the body portion and being an extension of the hollow cylindrical core with the large diameter end of the protuberance being the same diameter as the cylindrical core, whereby a second spool or a bobbin is capable of being attached in series with the thread spool by a hollow core of the second spool or bobbin frictionally engaging said conical protuberance.
