ABSTRACT:
A sewing machine with an automatic threader comprises a threading hook for threading a needle, a thread carrying member for passing a thread through a thread take-up spring, a thread holding device for extending the thread from a thread take-up lever near to the thread eye of the needle so that the threading hook is able to catch the thread, an actuating lever for moving the thread holding device releasably holding the thread near to the needle and making the thread holding device transfer the thread to the threading hook, and an operating member for operating the thread carrying member and the actuating lever. These components of the automatic threader are interlocked with each other so that the thread is extended to the threading hook and is passed through the thread eye of the needle automatically by the single downward stroke of the operating member.
