  • Needle centering device and cutter for a zig-zag sewing machine
    Patent number: 4592297
    Abstract: A mechanism for trimming the thread on a sewing machine with a laterally oscillating needle has devices for shifting the amplitude of needle oscillation to a center or zero position and for cutting both needle and bobbin threads. Thread connected to a workpiece is easily cut by actuation of the shift device to move the needle to the center position at which time the thread cutting device is actuated to cut the sewing machine needle and bobbin threads.
