Definitions

  • This invention relates to spindles for spinning frames.
  • An object of the present invention is to provide improvements in spindles by which the required number of turns of the yarn end around the spindle tip will be maintained thereby eliminating the danger of the yarn being broken at its point of delivery from the front drawing rolls.
  • Fig. l is a more or less diagrammatical view showing a spindle embodying the present invention.
  • Fig. 2 is an enlarged side view of the upper end of the nose portion of the spindle.
  • Fig. 3 is a. side view of Fig. 2.
  • Fig. 4 is a top plan view of the spindle.
  • Fig. 1, b indicate the front drawing rolls of the drafting section of a ring spinning frame, 0 being the bottom driven .roll and b being the upper pressure roll, 9 indicates a spindle on which is mounted a bobbin h to receive the spun yarn mass .1, 1 indicates the spinning ring of the spinning frame and ,f indicates the traveler mounted on said ring. 41 indicates the thread guide situated between the drawing rolls and the spindle and through which the yarn end passes.
  • the spindle g is provided with an extension or nose portion 6, the end m of which is enlarged slightly, and said nose portion is formed at its tip end with two fiat surfaces e 6 said surfaces converging slightly toward the end .of the spindle but having their end edges widely separated from each other, as shown in Figs. 3 and l.
  • the flat surfaces c e are widest at the tip of the spindle nose portion, .as indicated at it, because of the enlarged end 01 and the ,width of each flat surface at its widest point :kis very nearly the same as the diameter .of the .spindle nose immediately below the enlarged end portion.
  • the side wall portions ,p of the enlarged nose portion m between the edges of the fiat surfaces e e present segments of a cylindrical surface which is concentric with the axis of the spindle, and because of the wide separation of such flat surfaces where they cut the enlarged nose portion m, said segments span arcs of generous proportion.
  • the yarn 11, passes from the front drawing rolls b, c to and through the thread guide (2 and thence passes down along one of the flat faces e e and makes the requisite number of turns about the nose portion 6 of the spindle and thence passes to the traveler and to the yarn mass i.
  • thread guide 01 should be positioned closely adjacent to the end of the nose of the spindle as shown in Fig. 1 so that said guide will operate to maintain the yarn in contact with one of the flat faces.
  • the thread guide at may be of the usual pigtail variety, but it is desirable that the opening or eye of this thread guide shall be as small as possible and yet permit the yarn to pass freely therethrough, and it has been found that a pigtail guide made of piano wire having a diameter of approximately 1 mm. gives excellent results.
  • the thread guide is mounted with its thread-- receiving opening in axial alinement with the spindle, and as stated above, it is important that said thread guide should be so adjusted that the thread-receiving opening therein is very close to the end of the spindle nose because by this arrangement, said thread guide will maintain the yarn end passing therethrough in contact with the widened portion 7:: of one of the flat surfaces of the spindle nose and hence the desired number of turns of the yarn end around the spindle nose will be at all times maintained.
  • the curved surfaces p of the enlarged portion 121 are the thread guide
  • the convexly curved segments p of the surface of the enlarged end m are segments of a cylindrical surface, and since such segments project only slightly beyond the edges of the widest portion is of the fiat faces e c and therefore since the width of the flat surfaces at their widest portion 7a is at most only slightly greater than the diameter of the spindle nose immediately below the enlarged end m, the passing of the yarn off from either flat surface It around the adjacent surface 12 onto the other flat portion k is accomplished without subjecting the yarn to any very appreciable increased strain so that said passage from one flat surface to the other is an easy passage.
  • a ring spinning machine of the type comprising a rotatable spindle around which the yarn being spun makes several turns before it passes to the traveler, the combination with said spindle having a slightly enlarged tip end immediately above the portion around which the yarn passes and also having two oppositely disposed flat surfaces which converge slightly towardthe spindle tip and over one of which the yarn is fed, the upper end edges of said flat surfaces being widely separated and the side wall surfaces of said enlarged tip portion between the edges of the flat surfaces being segments of a cylindrical surface which is concentric with the spindle axis and which span generous arcs, the widest portion of each fiat surface being at the outer end of the enlarged portion of the spindle tip, and having a width approximating the diameter of the spindle immediately below said enlarged portions around which the turns of the yarn pass, whereby if during the spinning operation the yarn rolls off from either flat surface onto the other flat surface, said yarn will not be subjected to any very appreciable strain as it passes around the convexly curved segment
