Auxiliary presser foot for engaging a previously formed stitch

摘要

An auxiliary presser foot mechanism is mounted in a sewing machine with the auxiliary presser foot member being biased onto one or more previously formed stitches so that the previously formed stitches will not be unduly tensioned by the operation of the thread takeup lever during the formation of the new stitch. A cam mechanism is provided for raising the auxiliary presser foot during the feeding of the workpiece and spring means are provided for pressing the auxiliary presser foot against the previously formed stitches when the sewing machine feed dog is lowered beneath the throat plate of the sewing machine.
