Howe, the American inventor, secured a patent for an improvement in sewing-machines, which embodied the main features of the machine used at present; to wit, a grooved needle provided with an eye near its point, a shuttle operating on the side of the cloth opposite the needle to form a lockstitch, and an automatic feed.

Then the take-up arm pulls the excess upper thread (from the bobbin area) back to the top forming the lockstitch ideally in the center of the thickness of the material, the tension mechanism prevents the thread from being pulled from the spool side, the needle is pulled out of the cloth, and the feed dogs pull the cloth back one stitch length, the cycle is repeated as the machine turns mechanically.
