Abstract

534,438. Sewing-machines. SINGER MANUFACTURING CO. Feb. 24, 1940, No. 3486. Convention date, April 21, 1939. [Class 112] A chain-stitch looper, or other thread handling device, 24 is carried on the end of a shaft 20 which is oscillated by means of a yoke 21 and an eccentric on a parallel shaft 14. The shaft 20 is mounted eccentrically within a shaft 18 which is continuously rotated by gears from shaft 14. The curve 32 is the resulting path of the looper tip. The looper beak enters the needle loop in a nearly normal attitude and in the return movement, owing to the upward shift of the shaft 20, the beak is substantially oblique to the needle.
