Abstract

28,992. Fairweather, W., [Singer Manufacturing Co.]. Dec. 14. S e w i n g - m a c h i n e s ; needles, driving; feed by dog.-The needle-bar and feed-dog are rendered inoperative simultaneously at the close of a stitching operation instead of wholly disconnecting the machine from t h e power-transmitting device. In the construction shown in Figs. 2 and 3, a sleeve 46 fitting loosely upon the needlebar 42 is pivotally mounted within the crank-pin of a crank 39. Normally the needle-bar is operatively connected to it by a spring-pressed pin 48 within the crankpin, which engages a notch 61 in the needlebar. When the stop treadle is depressed, a sleeve 51 surrounding the upper end of the needle - bar is turned slightly. On the next ascent of the needle-bar, a lug 42<1> upon it engages with a camsurface 53, thereby twisting the needle-bar a n d disengaging t h e notch 51 and pin 48. T h e feed - traversing eccentric 18 is pivoted to the pulley 16, and is h e l d normally by a spring 19 in its most eccentric position. On the operation of the stop-treadle, a rod 21 is moved towards the left, and its pointed end 20, bearing upon a pin 22, forces the eccentric into a concentric position, so rendering the feed inoperative. Fig. 9 shows another construction. Both feed eccentrics are adjusted as explained above by the displacement of a rod 81. This rod is prolonged, is prevented from rotation relative to the shaft 10, and carries a helical-toothed wheel 86 gearing with a corresponding segment 87 on a pin 88<1>, to which is secured an arm 89 carrying the needle-driving crank 90. When the rod 81 is displaced towards the left, the gear-wheels 86, 87 swing the arm 89 and bring the crank 90 into a position concentric with the shaft 10. In a third construction, the stitch regulating suspension link of a known form of cam-actuated feed-shaft operating rod is connected to a lever on a control shaft.
