Abstract

189,694. Cooper, J., and Twin Bobbin Sewing Machine Co., Ltd. Feb. 9, 1922. Lock-stitching by hooks; upper and lower shafts, connecting.-A rotary hcok 14 is actuated by a crank 30 and drag link connection with one end of a lever 13 which compounds motions received from two cams on the main shaft. The lever 13 is pivoted upon a lever 20, receives rocking movements about its pivot 19 from a cam-actuated lever 18, and is moved bodily by the oscillation of the lever 20 from a second cam-actuated lever 8.
