Abstract
171,861. Bingham, J., and Heney, W. Oct. 9, 1920. Sewing-machines; needles, vibrating laterally; chain-stitching; presser-bars; feed by dogs.-A framework 1, including the usual overhanging arm, carrying the stitch-forming devices but not presser and feed, is pivoted at 5 and oscillated to produce a zig-zag stitch by means of a switchcam 26, slotted lever 17 and pitman 15. The amplitude of the vibration'is raised by means of a lever 23 and link 22, and the field is varied by moving the pivot of the lever 17 which for this purpose is carried by a lever 20. The needle-bar and loop-taker shafts are driven with cyclical variations in speed by means of a drag-link connection 34. The loop-taker is given axial needleavoiding movements by means of a pitman 41 and a cam 40. The presser-foot is fixed to a lever spring 49 secured upon a shaft 50 supported at 51, 52 independently of the framework 1, and can be lifted by means of a cam-lever 54 acting upon a lever-arm 53. A feed-bar 45 is universally mounted at 47 and actuated by a single cam 43.
