Abstract: 16,282. Berthold Sohn, B. July 7, 1909, [Convention date]. Tying or knotting.-The skeins of a lea are bound automatically upon a reel by a binding-thread, which is held outside the reel, and is presented by a thread-guide to a looper or latch needle, which emerges at given moments through the spaces between the skeins, and which hooks the binding-thread and draws it down, binding it into a loop round the skein in the manner employed in knitting. At the end of the lea the two ends of the binding thread and the two ends of the lea thread are all knitted together. Two pieces or walls 7, Fig. 1, are rotatably mounted on a spindle 10 and carry the spools 78, on which the binding-threads 31 are wound, and the various binding and knotting attachments. A separate set of devices is employed for each lea on the reel. The device, which is shown in operative position, can be rotated by hand about the spindle 10 to allow the leas to be removed from the reel. A looper 22 taking the form of a latch needle, is carried by an arm 18, mounted in bearings 19 carried by bar 14 supported by arms 13, which are rocked about the spindle 10 by an eccentric 9 on a driving-spindle 8. The upper end 15 of the arm 18 is attached to a bar 21, which can be moved intermittently, in the direction of its length to move the looper step by step to positions between the skeins forming the lea. The pieces 7 also support a rod 26 and shafts 27, 29, from which depend a skein-divider 23, an arm 28 having a threadguide eye at its lower end, and an arm 30, respectively. The shafts 27, 29 are arranged to oscillate about their axes and also to move in a direction parallel to their axes at the required times. The arm 30, Fig. 6, carries at its lower end a pair of shears 33, 34, a spring elamp 35 to hold the beginning of the binding-thread, a thread-guide 37, a clamp 36 co-operating with a grooved part 30<1>, and a threading- plate 38, into which the end of the lea thread enters as the device descends into operative position. The movable parts are actuated from a spindle 32 passing through the arms 30 and carrying an arm 39 having a pin-and-slot connexion with an arm 41. The beginning of the lea thread is secured in a weighted socket 51, which slides on a light bar 50 arranged to be turned by a handle on a spindle 48, and passes thence over a guide 52 to the reel. During reeling, the bar 50 is turned into the position 50<1>. The binding-thread is kept taut by passing it from the spool 78 over bars 75, 81, and under an arm 77 controlled by a spring or eccentric. The end of the binding-thread 31 is secured in the clamp 35, it is then passed through the thread-guide 28, which is originally situated at the outside of the first skein and is carried by it, by an oscillating and then a longitudinal movement of the spindle 27, as shown in Fig. 7, round the looper 22, which has meanwhile been raised by the action of the eccentric 9. The looper 22 then descends, taking the binding-thread with it and forming a loop round the first skein. It is then moved forwards by the movement of the bar 21 and raised again between the first and second skeins. In the meantime the arm 30 has been oscillated to carry the end 31<1> of the binding-thread over to the back of the looper 22. The thread-guide 28 is then swung forward to bring the thread into engagement with the looper, which descends again, drawing a loop through the previously formed loop, as shown in Fig. 9. The arm 30 then swings back into its original position, the thread-guide 28 is moved forwards a step, the looper rises between the second and third skeins, the thread-guide swings over to lay the thread under the hook of the looper, the looper descends, and thus forms a loop round the second skein, as shown in Fig. 11, the thread 31<1> being threaded through the loop. In this way the remaining skeins are bound until the looper is ready to rise between the last and the last but one. The arm 30 is then moved by a longitudinal displacement of the shaft 29 into a position 30', Fig. 13, carrying the end thread 55 of the lea behind the looper. The looper then rises and the arm 30 moves back into its original position, the thread-guide 28 swings over as before, and the looper descending draws with it in addition to the binding-thread the end thread 55 of the lea. The spindle 48 is then rotated, carrying the thread-guide 52, and with it the beginning and the end threads of the lea, over to the other side of the looper, which then rises beyond the last skein. The threadguide 52 then moves back, and the thread-guide 28 swings over, laying the threads 54, 55, 31 under the looper, which descends, drawing them all through the loop, and forming the loop round the last skein. The thread-guide 52 is again swung over, and the looper rises again. This time in addition to the binding-thread 31, and the end threads of the lea being laid under the looper by movements of the guides 52, 28, the binding-thread 31<1> is also laid under the looper by a swinging movement of the arm 30 as shown in Fig. 17. The looper then descends again and draws all four threads through the previously formed loop. The shaft 32 is now oscillated, the clamping-spring 35 is opened, releasing the beginning 31<1> of the binding- thread, and the shears are opened. The threadguides 28, 52 now move longitudinally further away from the skein and are swung over, laying their threads 54, 55, 31 in the open shear jaws, which are then closed, severing the threads. The looper 22 in its descent pulls the threads through the loop, forming the final knot, as shown in Fig. 20, and tightens it by its movement back to its original position, by pulling the threads through the final knot-clamping spring 36. The severed end of the binding- thread is secured in the clamp 35 on the closing of the shears jaws, and the movement of the thread-guide 28 back to its original position draws the thread 31 through 'the guide 37. The finished binding is shown in Fig. 21.
