Abstract

1,255,517. Positive clutches. NECCHI S.p.A. 22 Sept., 1969 [23 Sept., 1968], No. 46524/69. Heading F2C. [Also in Division D1] A bobbin supporting pin 22, driven by a driven input shaft 14 of a sewing machine, is coupled by a pivoted lever 24 to a pulley 35 which transmits the drive to the driving shaft of the machine, the lever 24 being tilted to disengage from the pulley 35 when a bobbin is placed on pin 22 for winding thread thereon. The lever 24 is pivoted at 23 in a slot in the pin 22 and its arm has a tooth 29 engaging, under the influence of spring 27, in a tapered slot in the pulley 35. The pulley 35, member 22 and lever 24 may be of plastics material.
