Abstract
A sewing machine cassette threading system in which the thread handling instrumentalities of a sewing machine are arranged to accept thread from either a cassette or a conventional thread spool with a minimum of operator intervention. The sewing machine has a chamber formed therein to accept the cassette. The sewing machine thread handling instrumentalities are threaded by inserting a cassette into a cover enclosing the chamber and closing the cover. Thread from a conventional spool carried on the sewing machine arm may be placed in the cover for insertion into the thread handling instrumentalities when the cover is closed.
