3913. Mackie, J. Sept. 25, 1912, [Convention date]. Thread-spooling machines; balling-machines. -In a machine for winding thread, yarn, twine, &c. upon spools by means of a flyer inclined relatively to the axis of the spindle, the spools are fed automatically from a reserve and secured upon hollow spindles by hooked clamping-devices eccentrically mounted in and capable of being drawn within the bore of the spindles, and a needle is arranged and operated to receive the end of the thread and, after it has been severed, to draw it beneath the last turn or turns. The mechanism is controlled from four principal shafts, viz.: -a main shaft 1, Fig. 2, a driven or pulley shaft 2 which drives the flyers, a barring-shaft 4, and a cam-shaft 5. The shaft 2 drives the shaft 1 through gearing 1<a>, 1<d>, 1<f>, 1<g>, and is provided with a fast pulley 2<1>, a loose pulley 2<2>, and a loose pulley 3 connected by gearing 3<b>, 3<c>, 3<f>, 3<h>, 3<i> with the shaft 4, which is geared with the shaft 5 so that they rotate synchronously and make one revolution during each cycle of the machine. The shaft 2 revolves with the belt on the pulley 2<1> and drives the flyers until a cam thereon operates a rod 14 and releases a pawl 8, and thus allows a spring 11 to move the shipper-rod 10 and shift the belt on to the pulley 3, thereby driving the barring- shaft 4, which, by its revolution, operates a lever 7 through a cam 6 to move the belt back again on to the pulley 2<1> after the ending operations are completed. The shaft 4 also operates by means of a cam, lever 21, and ratchet gearing 17, 19, the shaft 2, so that for a time during the ending operations the flyers are revolved to wind the turns referred to above. The pawl is withheld while the belt is on pulley 2' by a cam on the shipper-rod slide. Spools are placed in a shoot 28, Fig. 20, opposite each spindle, and are conveyed along it by a chain 29 driven from the main shaft, and delivered singly by means of a lever device, which operates as a gate, to a yoke 32, which is tilted by means of a rod 37 and a cam on the main shaft and elevated by means of another rod and cam also on the main shaft, so that each spool is lifted into a vertical shoot 42, wherein it is retained by a spring catch. The entrance of successive spools displaces the topmost spool on to a spring-pin 45, which is oscillated by a cam and lever to place the spool on to a pin 52 mounted on a slide 53, which is moved to dispose the spool between the jaws of a spring clamp 57, which is then turned about the axis of its carrying- shaft 59 by a sector 60, a co-operating lever being arranged to give the shaft 59 a sharp backward impulse or quick return when the spool is mounted on the spindle. The spindle is mounted in a frame pivoted about the shaft 5 and is driven from the shaft 2. The clamping- spindle comprises a hollow rod 62, Fig. 22, capable of being moved relatively to the main spindle for a distance equal to the length of the spool, and provided with an eccentricallymounted hooked rod 76, which is rotated by a longitudinally-movable rack 80 to unclamp or to clamp the spool. The spindle-frame is tilted, by means of cams on the main shaft, so that the final coils are wound more obliquely than the main coils. When the belt is moved on to the pulley 3, a cam on the cam shaft rocks a shaft 88, Fig. 23, and together with a switch device 91 moves a needle 94 on the lever 89 into proximity to the spool where it is retained during the time that two of the three turns, caused by the rotation of the shaft 2 by the ratchet gear 17, 19, are wound; when the third turn is wound, the lever 89 is moved by the switch so that the thread is caught by the hook and also gripped in a clamp 97 and by further movement is drawn beneath the last two turns. The thread is cut by a knife 113, and, after new spools have been mounted and a few turns wound, is released from the clamp. In order to ensure a quick arrest of the shaft 2 and pulley 3, brakes 127, 130 are applied thereto and are released by cams 129, 132 on the shipper-rod slide. The finished spools drop on to a conveyer which removes them from the machine.
