ABSTRACT:
An automatic needle threader, which uses compressed air to thread the needles of sewing machines, has means for imparting a rotational or swirling motion to the air which smooths out the frayed ends of the thread for easier and more positive threading. The compressed air is directed into an air chamber in which a spiral shaped baffle is mounted to impart the swirling motion. The threader can be permanently mounted on a sewing machine with a hinge connection allowing the threader to be moved out of position when not in use and to be moved into position so that the exiting end of the air chamber is located adjacent and opposite the eye of the needle. Alternatively, the threader may be removably mounted to a sewing machine using straps connected to the hinge.
