摘要:
An improved visual aid mechanism for a presser device for facilitating the making of buttonholes. The mechanism will sense and indicate to the operator the approaching end of the first leg of a buttonhole being sewn whose length has been preset by the operator. This invention utilizes flexible fingers which are substantially deflected by an adjustable stop member to provide a magnified visual indication. Thus the operator may stop the sewing operation very precisely resulting in buttonholes of consistently uniform length and quality.
