Automatic Needle Threader Views
An automatic needle threader is a feature on many sewing machines that allows you to more easily thread the needle. By using it, you can avoid straining your eyes and trying to keep your hand steady to direct the tip of a piece of thread into a tiny needle hole. An automatic needle threader consists of a spring-type hook-and-lever operation that forces a loop of thread into the hole of the needle.

However, an automatic needle threader which uses compressed air and which creates a rotating or swirling motion to the air to force the loose fibers created by fraying at or near the end of the thread back toward the body of the thread, as does the instant invention, thereby improving, and eliminating problems associated with, the needle threading process, is not shown in the prior art. OBJECTS OF THE INVENTION
These and other objects of the instant invention are achieved by providing an automatic needle threader which is hingedly attached to a sewing machine and which applies compressed air to a funnel having a helical baffle. As the compressed air flows through the funnel, toward the spout end of the device, the compressed air pushes the end of the thread forward through the eye of the needle while, at the same time, the frayed end of the thread is smoothed out by the swirling of the compressed air. This assures that the needle will be threaded without the difficulty associated with loose fibers due to fraying at the end of the thread.
Referring now in greater detail to the various figures of the drawing, wherein like reference characters refer to like parts, there is shown in FIGS. 1 and 2 the automatic needle threader 2 of the instant invention attached to a sewing machine 4. The automatic needle threader 2 has a housing 6 in which is mounted a solenoid 8. The housing 6 is connected to an S-shaped tubular air chamber 10 which has a proximal section 12, a funnel section 14 and a spout section 16.
