Abstract
256,787. Francis, C. E. Aug. 21, 1925.

The seam formed resembles an ordinary lock. stitch seam with the exception that the first stitch 9 has no loose ends. A sewing-machine may be specially adapted for forming this seam by providing a wedging device 23 for scotching theneedle-bar and device 21 for releasing the tension 22 operated by a lever 20. A bobbin winder is disposed close to the loop-taker so as to avoid slack thread and means may be provided for indicating when a required amount of thread hasbeen wound.
