Abstract

189,695. Cooper, J., and Twin Bobbin Sewing Machine Co., Ltd. Feb. 9, 1922. Sewing-machines; feed by dogs.-A feed-bar M receives up-and-down movements from a camgroove in the boss of a lever 20 forming part of the rotary hook driving mechanism. For the to-and-fro movements, a grooved arm C is fixed on the feed rock-shaft A and is engaged by a pin which also slides in a groove in a fixed arm F. The pin is carried in the end of a link E reciprocated by connection with an oscillating lever 13. The length of stitch is regulated by changing the inclination of the fixed arm F.
