Abstract
This invention relates to a needle guard which is adapted to position the needle relative the lower stitch forming mechanism and further serves to minimize skipped stitches during the sewing operation. The needle guard is positioned beneath the work supporting surface of the machine and during the sewing operation is disposed proximate the needle path. Upon completion of the sewing operation the needle guard is retracted from the path of the needle. Adjustable means are provided so as to accomodate the needle guard to needles of various sizes and to permit positioning of the needle guiding surface with respect to the path of the needle.
