Abstract

215,660. Armstrong, J. J. V., (Union Special Machine Co.). Oct. 12, 1923. Overhead sewing-machines.-Both feed-wheels are directly actuated so as to rotate intermittently in unison. The inner feed-wheel 5 is actuated through an intermittent clutch mechanism by a lever 8 on a shaft 9 which is oscillated by an eccentric on the main shaft 2. The shaft 20 of the out feed wheel 6 carries a disc 21, a flange 22 on which engages slotted spring- controlled dogs 23. The dogs 23 engage in recesses 24 in an oscillating sleeve 25 and act as intermittent friction-ratchet feed. Retrograde movement of this device is prevented by a spring- controlled dog 32. A link 28<1> ball-jointed to a lever 31 on the shaft 9 and to an arm 27 on the sleeve 25, actuates the sleeve. The feed is varied by adjusting the effective lengths of the levers 8, 31. The outer feed-wheel mechanism is carried by an arm 13 fixed to a rod 17 pivoted in a bracket 14 adjustably mounted on the casing. A lever 18 fixed to the rod 17 is spring pressed to hold the wheels 5, 6 pressed together, and is treadle actuated to separate the wheels for inserting the work, stops 36 being provided.
