Abstract
185,062. Willcox & Gibbs Sewing Machine Co., Ltd., (Willcox & Gibbs Sewing Machine Co.). Jan. 13, 1922. Sewing-machines; thread-tensioning devices.-A tension-device comprises several tension means separately adjustable to vary the tension of each thread but all adapted to be put into or out of operation simultaneously on the movement of another part such as the presser-foot. The threads are passed through tubular guides 34 and between tension springs 30, separately by screws 35, and a plate 23 pivoted at 25 to the frame of the tension-device. A lug 26 on the hinged plate engages a stepped recess 27, 28 in a rod 18 rigidly connected to a shaft 16 movable endwise agamst a spring 19 by an arm 21 connected to the presser-foot. When the lug 26 rests on the part 28 of the reeess, the plate 23 is held in a forward position to nip the threads; when the rod 18 is shifted to allow the lug to drop into the lower part 27 of the recess, the plate moves away from the springs to release the threads. The device is specially applicable to machines of the kind described in Specifications 6036/12 and 6037/12.
