Abstract
177,738. Fairweather, W., (Singer Manufacturing Co.). June 20, 1921. Thread-cutters and thread-end holders.-At the end of a stitching cycle, the last needle-thread loop is spread by a looper 80, and one limb is cut by a cutter 39, which bears vieldingly against the underside of the throat-plate p, and co-operates with a ledger-blade 40. The parts 30, 39 are integral with an arm 32, fixed to a sector gear 33, which is actuated from the stop-motion lever in the usual manner. An under-thread severing- blade 26, and a needle-thread nipper 36 are also secured to the arm 32. A forked arm 44 of a slotted lever 43, actuated by an arm 47 of the sector gears, nips the underthread, which is severed by the cutting-edge 29, Fig. 5, of the blade 26. When stitching is re-commenced, the needle descends and the shuttle draws down the loose thread end. The sector gear is then actuated to draw back the thread-nipper 36, which holds the thread-end during several stitches, after which the parts are wholly retracted.
