Definitions

  • the present invention relates to an elongated traveler traveling on a spinning ring around a spindle, the spinning ring having a flange whose cross sectional configuration corresponds to that known in Europe as form No. I or No. II which substantially corresponds to forms I and II of the American classification.
  • flange II is the same as that of flange I, flange II being larger than flange I.
  • the flange has a head resting on a vertical web having parallel walls.
  • the head has a horizontal plane top surface.
  • the cross section of the head is oblong, the long axis being horizontal and the ends of the cross section being formed by convex almost complete semicircles whose radii amount to about one half of the vertical thickness of the head.
  • the lower ends of these lateral semicircles are connected to the web by downwardly slanted lines placed at an angle of 100 with respect to the vertical walls of the web.
  • the size and position of the arc portion of the traveler which guides the thread so that the position of the traveler is changed very little when the greatness and direction of the pull of the thread are changed during building up of the cop.
  • the position and configuration of the legs of the traveler must be so coordinated to the flange that, while maintaining a minimal freedom of the running surfaces of the legs of the traveler, i.e. freedom of self-adjustment of the position of the traveler, the embracement of the ring flange by the traveler is as great as possible without impairing the stability of movement of the traveler.
  • the traveler according to the invention when traveling on a ring flange having a cross sectional configuration known as form No. I and No. II and described above whereby the radius of the arc of the traveler resting on the flange of the spinning ring corresponds to the radius p of the curvature of the lower inner surface of the ring flange which is the running surface, and the arc of the traveler guiding the thread is part of a circle having a radius 2.15 p.
  • the distance between the center of the arc guiding the thread and the center of the arc resting on the ring flange is 1.15 p and the vertical distance of the center of the arc guiding the thread from the radius extending from the center of the arc resting on the ring flange to the upper end of the last mentioned are is about 0.3 p.
  • an intermediate inside surface portion of the traveler is provided between the arc resting on the ring flange and the arc guiding the thread which intermediate surface portion is substantially parallel to the axis of symmetry of the traveler and prevents clamping of the thread between the ring flange and the traveler, as happens quite frequently with conventional elliptic travelers which do not have this intermediate surface portion.
  • the resultant of the thread tension whose greatness and position undulate between two extreme values, produces a constant torque acting on the traveler with respect to the center of gravity of its support whereby a noticeable movement of the traveler in addition to its rotating movement is avoided.
  • the resultant size of the surfaces of the ring flange and of the traveler engaging each other is so that there is a sufliciently stable support of the traveler and suflicient heat removal from the engaging surfaces. Since the travelers with which the invention is concerned are very small, a 10% deviation of the afore-discussed dimensions below and above the optimal values is tenable.
  • FIG. 1 is a part sectional elevation of a portion of a ring rail on which a spinning ring is mounted for guiding a traveler around acop which is being built up.
  • FIG. 2 is a large scale illustration of a conventional (Z-shaped traveler in operating position on a flange of a spinning ring.
  • FIG. 3 is a large scale illustration of a different conventional traveler.
  • FIG. 4 is a large scale illustration of a conventional elliptic traveler.
  • FIG. 5 is a large scale illustration of a traveler according to the invention in operating position on the flange of a spinning ring.
  • FIG. 6 is an illustration of the traveler shown in FIG. 5, showing structural details.
  • numeral 1 designates a traveler traveling on a spinning ring 2 which is mounted in the conventional manner on a ring rail '3 of a spinning machine.
  • a flange 4 forming the upper part of the ring 2 has the configuration which is known as form number I which has been described above.
  • the ring rail 3 is mounted in the conventional manner on a mechanism, not shown, for moving the rail vertically up and down whereby the extent of the movement corresponds to the height of the conical part 5 of a cop 6. It is Well known that the forces exerted by the thread on the traveler are greatest when the thread is wound on the upper part 7 of the conical portion 5 and are smallest when the thread is Wound at the base 8 of the conical portion 5 of the cop.
  • the G-shaped traveler 9 shown in FIG. 2 is considerably tilted and engages two surface portions of the flange 4 'because the radius of the are portion 10* which is adjacent to the flange is smaller than that of the curvature of the opposite surface 11 of the flange 4. This makes the movement of the traveler unstable.
  • the tilting motion is due to the much too great radius of the arc portion 12 of the traveler which guides the thread. This tilting motion may even cause temporary engagement of the end 13 of the left part of the traveler with the outer surface of the web portion v14 of the spinning ring.
  • the traveler 17 shown in FIG. 3 has a more flat center portion than the traveler 9 shown in FIG. 2. Aside from the tilting effect of this configuration, it also reduces removal of frictional heat because the radius of the arc portion of the traveler which engages the flange of the spinning ring is much greater than the radius of the curvature of the engaged part of the flange so that the engaging surfaces are small and little heat is conducted from the traveler into the spinning ring.
  • the elliptic spinning ring 18 shown in FIG. 4 has a somewhat more. favorable configuration because it is more elongated than the rings shown in FIGS. 2 and 3 and is less likely to tilt.
  • This traveler forms a rather narrow tapered space between the inner upper surface 19 of the flange of the spinning ring and the arc portion 20 of the traveler which guides the thread so that the latter may 'be clamped between the ring and the flange.
  • the traveler 21 shown in FIGS. and 6 has a much more favorable configuration and avoids the disadvantages of conventional configurations.
  • the radius p of the arc portion 22 of the traveler which engages the flange of the spinning ring corresponds exactly to that of the curvature of the lower inner surface of the flange which is engaged 'by the traveler.
  • the center of the circle including the surface of the traveler which engages the flange of the spinning ring coincides with the center of the circle a portion of which coincides with the curvature of the lower inner surface of the. flange of the spinning ring and is designated by Z in FIG. 6.
  • the are portion 22 extends through an angle ea of at least 65 between points A and B.
  • the are portion 22 continues upwardly into an intermediate portion 23 which will be described later and whose upper end continues into an arc portion 24 which guides the thread.
  • the distance b between the center Z of the portion 24 and the center Z of the arc portion 22 amounts to about 1.15 p and the vertical'distance a between the diameter extending through Z and B and the center Z amounts to about 0.3 p.
  • the radius R of the arc portion 24 is approximat-sly 2.15 p.
  • the lower end C of the arc portion 24 is placed on a line extending through Z and being inclined to the line Z B at anangle p.
  • the upper end D of the arc portion 24 is located at the end of a'radius Z D which is spaced from the radius Z 0 at an angle 7 of approximately 45.
  • the traveler is symmetrical and the left portion is-mirro-symmetric to the right portion, the two end portions being connected by an intermediate portion 25 preferably so shaped that the location of the center of gravity of the traveler best suits the flange number I or II with which the traveler cooperates.
  • the same is the case with the end portion 26 continuing beyond the point A tangentially of the circle having the radius p whereby the inclination of the portion 26 is defined by the angle a.
  • the angle a is preferably increased to about 80 to 85 whereas this angle amounts to about 65 in travelers which are used to run on flange number I.
  • the intermediate part 23 of the traveler extends at point B tangentially from the arc portion 22 until the portion 23 intersects the circle around the center Z with the radius R, the connection of the arc portion 23 to the arc portion 24 being smoothed.
  • the portion 23 which is substantially parallel to the axis of symmetry S of the traveler is of great importance because it produces a much greater diversion between the inner upper surface of the flange of the spinning ring and the inner surface of the traveler than is produced by a traveler, for example, as shown in FIG. 4, so that the thread when being wound on the top 7 of the conical portion 5 of the cop 6 and when the resultant of the thread tension is great may move quite far down without danger that the thread be clamped between the traveler and the spinning ring.
  • a differently shaped traveler would have to be used for diiferent spinning conditions defined by the relative geometric arrangement of the parts.
  • the travelers shape according to the invention has been found on the basis of conventional arrangements. In order to change the position of the traveler as little as possible, if the traveler is used in connection with a different arrangement, the thread runs through the traveler according to the invention at a much lower elevation than it would run through conventional travelers so that the r sultant moment of the thread force'with respect to the center of gravity of the support of the traveler is small.
  • a traveler having an elongated configuration for coperation with a spinning ring having a flange whose cross sectional configuration includes an oblong head portion whose long axis is normal to a vertical web portion having parallel walls, the lateral ends of the head portion being convex and substantially semicircular, the lower ends ofthe semicircles being connected to the web by downwardly slanted lines placed at an angle of with respect to the vertical, the traveler having an arcuate portion sliding on the flange of the spinning ring and extending over at least 65, the radius of said arcuate portion corresponding to the radius of the curvature of the lower inner surface portion of the flange of the spinning ring on which the traveler runs, the traveler having a second arcuate portion for guiding the thread, the radius of said second arcuate portion being approximately 2.15 times the radius of the curvature of the lower inner surface of the flange of the spinning ring on which the traveler runs, the distance between the center of the arcuate portion guiding the thread and the
  • a traveler as defined in claim 1 having a symmetric configuration, and intermediate portions individually interposed between said arcuate portions guiding the thread and said arcuate portions sliding on the flange of the spining ring, said intermediate portions being substantially parallel to the axis of symmetry of the traveler.
