Abstract

179,092. Flanagan, J. A. June 27, 192]. Sewing-machines; feed by dogs. - A tubular feed-shaft 5 is actuated by means of a link 20 adjustably connected to an oscillating slotted lever 16 and the adjustment of its connection is determined by means of a bell-crank lever 25 having a pin 24 which engages in a slot 23 in the link 20- The other arm of the lever 25 has its movement limited by stops in the form of nuts 31, 32, on a right and left-handed screw 36. The lever 25 is oscillated bv a knee-lever 46a on a rock-shaft 44, and can be locked in place by a nut 30. Upper and lower shafts, connecting.-The hookshaft 4 is rotated irregularly by means of a slotted crank 8 and a pin 9 at one end of a pitman 10 which has a sliding-rocking control at 14 and which is actuated by a rotating crank 11 on the needle-shaft.
