Definitions

  • This invention relates to the textile industry and is particularly concerned with an improvement applicable to each lspindle in a Spinning frame. More particularly the invention is @concerned with ring spinning in which the yarn comes to the spindle from feed rolls located thereabove, passes through an eye axially aligned with the spindle, then downwardly to the traveler on the spinning ring and finally is wound on the bobbin on the spindle.
  • the yarn between the eye and the traveler will normally assume a configuration known as a balloon. This is objectionable when the spindles are close because the balloon of one spindle hits the balloon of the next, damaging the yarn.
  • Various anti-ballooning devices have been used.
  • One form which has come in to some use is a toothed mechanism added to the upper end of the spindle which engages the yarn asl it travels downwardly from the eye. This causes the yarn to rotate -at this position at spindle speed ⁇ and to wrap itself around the bobbin for a few turns on its yway to the traveler. Since the yarn is Wrapped around the bobbin as it moves to the traveler, ballooning is entirely eliminated.
  • the Weakest part of any yarn being spun is that portion which immediately leaves the bite of the feed rolls.
  • the object of all tension relieving devices is to relieve the yarn tension between the pot eye and the bite of the feed rolls which is caused by the traveler pull. By so doing, the production of the machine can be materially increased. Accordingly, with the yarn sufficiently strengthened by the twist applied ⁇ above the spindle, it may then be placed under greater tension as it is pulled Spirally down the bobbin to the traveler.
  • the present invention as far as causing the yarn to wind itself a few times around the bobbin as it moves from the guide eye to the traveler operates on the same principle as the disclosures in the above referred to British Patent and in United States Patent No. 3,032,960 of 196,2 to Kartmann.
  • the improvement, however, that constitutes the present invention resides in novel mechanism which functions automatically to cause the yarn to wind itself 3,107,479 Patented Oct. 22, 1963 about the bobbin in the first instance to prevent ballooning during the spinning operation and which automatically frees the yarn from connection with the upper end of the spindle during the decelerating period immediately prior to dofiing of the bobbin whereby the yarn may momentarily resume its typical balloon formation.
  • a further advantageous result produced by lthe mechanism which will be explained in detail hereinafter is that kinking of the yarn either during starting or stopping of the spindle is substantially eliminated.
  • FIG. 1 is a side elevation of a spindle mounted on a spindle rail with a bobbin thereon. The yarn is shown in the two positions it assumes during operation of the spindle;
  • FIG. 2 is an enlarged vertical cross-section of the upper end of the spindle and tension regulator
  • FIG. 3 is a section taken on the line 3-3 of FIG. 2 looking upwardly;
  • FIG. 4 is a plan view of FIG. 2 with the cover removed;
  • FIG. 5 is a side elevation of FIG. 4 showing the novel structure removed from the upper end of the spindle;
  • FIG. 6 is a side elevation of the cover
  • FIG. 7 is a bottom plan view of FIG. 6.
  • a spindle generally referred to at 2 is mounted on a spindle rail 4.
  • the particular construction of the spindle is immaterial tothe application of the invention except that the upper end of the spindle must be made in ⁇ a manner that will perm-it application thereto of the tension regulator generally referred to at 6.
  • the spindle includes a whorl 8 which is driven by a conventional :tape (not shown).
  • the spindle 10 per se is tubular and terminates at 12 at its upper end.
  • the bobbin is frictionally secured Ito the spindle at its upper end by .a set of pressure buttons 16 (see FIGS. 2 and 3) which are spaced 12.01 apart. A similar set of buttons (not shown) at the lower end of the spindle grip the -lower end of the bobbin.
  • the upper set of pressure buttons are mounted in the shank 18 of the body of the 4tension regulator while the lower set are in the spindle whorl.
  • the body of the regulator indicated at v20 has a circumferential vflange 22 which limits the extent of entry of the body 2o into spindle '10.
  • body 20 is in the form of ia cylindrical cavi-ty 24 into which is fitted a plug 26 having on its upper end a cylindrical extension 28 ywhich acts as a stop to Ilimit inward swinging motion of four elements 30 which are pivotally affixed -to the upper end of body 20.
  • the construction of the upper part of body 20 on which the elements 30 are mounted is as follows: Referring to FIGS. 2, 4 and 5, the body starting at shoulder 31 is o-f reduced diameter Iat 33 and terminates in a conical end 35. The upper end of the body down as far as 37 is slotted at right angles as at 32 and 34. This produces four supports or corner posts y40 with slots 36 therebetween. In each of the four slots is positioned an element 30. These elements lare freely pivoted on transversely extending pivot pins 318. The corner posts 40 have been cut away somewhat as at 42 for assembly of pins 33 for hold-ing elements 30.
  • each of the elements 30 has a radially extending finger 44 plainly shown in FIGS. 2, 4 and 5.
  • 'I'he pivoted elements 36 are held in an inwardly constrained position by a circular tension spring 46.
  • the inward movement of the lower ends of elements 30 is 'limited by engagement with the cylindrical extension 28 of plug 26.
  • the entire upper structure of body including the corner posts 40 and the pivoted elements 30 are protected by a cover 48 which makes a friction tight fit with the upper end of body 20 and rests at its lower edge on flange 22.
  • Cover 48 has its upper portion in the form of a truncated cone 50 and in the surface of this part are four openings 52 which are spaced at 90 and aligned with the fingers 44.
  • Spring 46 is of such strength that its constraining influence on elements 30 will not be overcome until the spindle reaches about 2500l rpm. The centrifugal force then acting on elements 30 is sufficient to stretch spring 46, causing the fingers 44, which had previously been within the conical surface 50 of cover 48, to extend through openings 52 an appreciable distance.
