ABSTRACT:
A buttonhole gauging presser device usable on sewing machines with or without automatic buttonhole mechanisms. This presser device includes button engaging projections which position both a cam for actuating an automatic buttonholing mechanism as well as visual indicating means. At the start of buttonhole sewing the visual indicating means occupies a position in advance of the sewing needle or indicia on the presser foot, and then as the buttonhole is stitched, the visual indicating means moves into alignment with the needle (or indicia) which serves a signal to the operator of a manual sewing machine that an operator-initiated action is required to have the sewing machine create a buttonhole end and reverse direction.
