Abstract
185,697. Fairweather, W., (Singer Manufacturing Co.). Jan. 11, 1922. Multiple-needle machines; governing needle thread.-A thread take-up carried by the needlebar comprises a plate 8 having an L-shaped thread aperture 10, Fig. 3. The thread is engaged by an horizontal portion lOb of the aperture until, in the descent of the plate, the thread contacts with a fixed oblique cage 21 and is pushed off the edge 10<c> into the upwardly inclined portion 10<a> of the aperture. The device is applied to a multiple-needle machine having one lcoper so as to provide that the several needle-thread loops shall be taken-up in pairs as they are cast-off the looper. Fig. 3 shows the application to a two-needle machine. The thread of one needle passes through the slot 10 and the thread of the other needle passes through an eye 9. Both threads pass over guide-arms 25, 26 Fig. 7, and the thread passing through the eye 9 lies above arms 15. In the first part of the descent of the needle-bar, the take-up gives up slack to each thread : then, when the first of the previously-formed loops is being cast off from the looper, the horizontal portion 10<b> of the L- shaped aperture in the take-up plate carries the supply side of the thread to that loop below the level of the arms 25, 26 and the slack of the freed thread-loop is thereby taken up : later, when the second thread-loop is cast-off, the supply side of its thread is carried by the eye 9 between the arms 15 and the slack of the loop is more rapidly taken-up. Shortly after the second loop is cast-off, the inclined edge 21 frees the thread from the edge 10<c>. A slack-thread controller operating on both threads is provided by a spring arm 29 which rests on the threads between the arms 25, 26. The upper limit of movement of the arm 29 is determined by a bridge piece 42 and the lower limit by an adjustable stop 37, Fig. 3. For machines having more than two needles the number of L-shaped apertures is increased and they are arranged to act in turn in conjunction with inclined edges such as 21. Fig. 5 shows a take-up plate for a three-needle machine.
