Abstract

230,999. Singer Manufacturing Co., Ltd., Corrall, H., and Heggie, J. March 26, 1924. Overhead sewing - machines.-The looper mechanism comprises a sleeve 2 surrounding the looper-bar 1 and moved to give endwise movements thereto by an oscillating lever 5 actuated by an eccentric on the shaft 9 and pivotally connected to a lateral arm 3 on the sleeve 2. A suspension link 10 pivoted to a collar on the sleeve 2 causes the bar 1 to tilt when moved endwise. The oscillating movements of the looper-bar are derived from an oscillating cam 14 pivoted at 15. actuated by an eccentric rod 16 from the shaft 9 and engaging a ball-stud 18 projecting from the bar 1. The thread is controlled by a nipping device comprising a tappet-arm 20 on the shaft 9 which engages the end of a screw 21 mounted on a lever 22 and causes a roller 23 on the lever to bear as the needle starts to retreat against' a part 24 of a thread-nipping device carried by the needle-bar 25.
