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.
