Abstract
181,897. Fairweather, W., (Singer Manufacturing Co.). April 21, 1921. Button-hole sewing-machines; needles, driving. -In a button-hole sewing-machine comprising rotary stitch-forming mechanism the needle-bar is driven by a link engaging a stud on the needlebar and a crank on a shaft below the work-plate, this link being free from other connection with the moving parts of the machine. The upper needle-bar is mounted in a frame 28 carried by posts 22, 26 which are secured in a travelling stitch-frame comprising a turret 2 for the looper mechanism and bearings 3, 4 which receive a bushing 5 and a tubular boss 6 carried by a bracket mounted on a stud pivoted in the bedplate of the machine. A driven bevel-wheel is journaled in the bracket and rotates a shaft 15 through a sliding connection. The shaft 15 terminates in a crank 31 connected by a pitman 34 and stud 36 to a reciprocating bar 38. Secured to the bar 38 is an arm 40 carrying a split boss 41 loosely surrounding a rotatable sleeve 42 which has at its upper end a crank 46. Mounted in a slot in the sleeve and secured to a needle bar 47 is a spline having lugs 52 embracing the boss 41 so that the reciprocating motion of the latter is transmitted to the needle bar which is also rotatable by the rotation of the sleeve 42. The eye-pointed needle 49 is mounted eccentrically in the needle bar.
