Latest Patents
Hermann Niehaus holds a patent for a "Controlled thread clamp device for needle threads." This invention is designed for use in double-needle lock-stitch sewing machines. The assembly effectively arrests threads being drawn from the needles during the uptake stroke of a thread lever. This mechanism ensures predetermined lengths of thread at the needles for the subsequent stitch. The device features a spring-loaded clamp positioned between the sewing lever and the needles, which is actuated periodically through a system of levers in the sewing-machine head. A cam mounted on the sewing-machine base interacts with a radial lug on a shaft that drives a rotary thread gripper and bobbin holder. Additionally, a spring-loaded plate engages a pair of thread-tension control disks, which are released upon actuation of the clamp. This clamp is particularly beneficial for controlling the length of the leading thread portion before starting a sewing seam.
