1,233,031. Sewing-machines. MEFINA S.A. 20 May, 1968 [9 June, 1967], No. 23870/68. Heading D1G. A thread tensioner for a sewing machine comprises two discs 8, 9 urged together by a spring 14 located between a nut 13 and a tubular part 3 on a shaft 2 which shaft may be. rotated by a knob 28, fixed on a hub thereon, to alter the tension by .movement of the shaft relative to the. nut 13 and the nut ; which may be of nylon is prevented from ; rotating by a part 19 which engages in slot ; in the nut, which part is on a lever 20 which lever is rotated about a pivot 21 to slide theshaft 2 and release the tension discs as lever 22 is rotated by the action of the presser foot as it leaves the work at the end of a stitching sequence. An additional" thread tensioning spring 40 is also provided surrounding the shaft 2.
