Abstract

183,873. Fairweather, W., (Singer Manufacturing Co.). Feb. 1, 1921. Clutches, friction, for sewing- machines.-The clutch C, Fig. 6, comprises a flanged driving disc 126, Fig. 11, which surrounds a driven disc 123 fixed to the rapid feed shaft 122. The driving disc is attached to a worm-wheel 135, which is revolubly mounted on the rapid feed shaft, and meshes with a worm on the continuously rotating shaft 138. The driven disc 123, has peripheral notches 124, with eccentric bottom walls; spring pressed clutch rolls, 128, in them engage the flange 127. Levers 130, pivoted upon the driven .disc, have lateral tail pieces 131 which project through slots 132, in a retainer plate 133. The cone 134, when forced towards the clutch, moves the tail pieces 131 outwards and the levers 130 force the clutch rolls, against their springs 129, out of driving contact with the flange 127.
