Abstract
An electronically controlled household sewing machine capable of effecting ornamental stitches by selective needle feed and needle positioning, in conjunction with reversible work feed. Means are provided for storing and returning needle jogging instructions intended to be accomplished not only while the needle is out of the work to provide zig zag stitches, but also intended to be accomplished while the needle is in the work to provide for lateral needle feed of the work. An arrangement is disclosed whereby combinations of zig zag, needle feed and longitudinal feed of the work may be influenced between successive needle penetrations. In this manner, in addition to the longitudinal work feed motion, the work material may be moved laterally by the sewing needle in the formation of ornamental patterns having unlimited width as well as longitudinal extent for which the stitch coordinate information is stored and applied to the stitch forming instrumentalities electronically.
