Abstract

185,690. Fairweather, W., (Singer Manufacturing Co.). Dec. 22, 1921. Loop-stitching; thread-cutters.-In a machine with a laterally vibrating work-holder means are provided for positioning the needle-thread loop uniformly in relation to a rotary looper 12 regardless of the position of the previous stitch, and for taking up temporarily the thread-loop slack after the loop has passed round the, outer end of the looper. The needle-thread loop is positioned by means of a fixed finger 18 and the. rotary looper 12 is given sideways movements for the purpcse of placing the loop upon the finger. The slack of the thread loop is taken up temporarily by a projection 14 on the looper which engages a limb of the loop. This prevents the loop from whipping round the end of the spur 18. A thread-cutter 22, Fig. 2, mounted on a bell-crank lever 23, is actuated to cut the thread by the. stop mechanism, through the draw-bar 25. An oscillating needle-guard is provided and a loop-controlling finger bears lightly on the looper surface.
