Abstract

554,546. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). June 20, 1942, No. 8506. [Class 112] In a four-motion feed bar mechanism, the feed-lift crank-pin 45 carries a slide-block 44 working in a curved slot 43 in the end of the feed-bar 40. The curvature of the slot is such that during the actual feeding movement the accelerating downward movement of the pin 45 is compensated by the relatively upward movement of the slotted end of the feed-bar as the horizontal movement of the feed-bar carries the slot over the pin.
