Needle positioning attachment for sewing machine

摘要

A needle positioning attachment connectable to the main drive shaft of a sewing machine in place of a pulley and handwheel assembly conventionally found on blind stitch and similar machines includes a resilient assembly for accumulating energy from rotation of the main drive shaft of the machine so as to use this accumulated energy for actuation of the needle positioning attachment when the main drive shaft ceases rotation. In this manner, the needle of the sewing machine will be positioned as desired for starting a new sewing operation each time the machine is deactuated.
