Abstract

176,657. Somerset & Co., Ltd., T., and Mahood, V. Feb. 28, 1921. Sewing-machines; needles, vibrating laterally. -A cam 3, interposed between the knee-lift lever 23 and its operating-rod 2, is used to impose automatic variations of the needle upon the variations obtained by means of the knee-lever. The cam is slidingly mounted on a spindle 14 and rests upon a U-shaped plate 17, forming one arm of the knee-lever, so that it can transmit the movements of the knee-lever. To actuate the rod 2 independently, the cam 3 is rotated from worm gear 12, 13 by means of a rod 16 fixed to the wheel 13 and to an arm on the upper end of the shaft 14, and passing through a perforation in the cam. The worm 12 is driven through gear 9, 10, 5, and 19 and may be put out of action by shifting the shaft 5 axially to separate the gear-wheels 19.
