摘要：
A household type lock stitch sewing machine wherein the ordinary under thread bobbin case may be replaced by a looper or collar member which may be detachably mounted on the stud of the shuttle, whereby the single upper thread engaging the needle eye may form a series of chain stitches by using the shuttle and the looper as hook means to draw or release the thread loop in timed relation with the movement of the needle and the feed dog.
