Definitions

  • the present invention relates to a holding device for spinning and twisting spindles, which avoids the undesirable lifting of the upper part of the spindle from the lower part of the spindle during change of spools.
  • All known holding devices have inherently the drawback, that they are subjected more or less to fly.
  • fibers are deposited on the mostly hookshaped holding devices due to the effect of an air stream created by the fast rotating spindle, which holding devices cannot easily be cleaned because they are on the side opposite to that from which the device is operated.
  • a main requirement for proper operation of the spindle is to avoid that the holding devices are subjected to the possibility of having fibers deposited thereon due to the created air stream, thus to transfer these devices, if possible, to the inside of the whorl.
  • the known attempts to avoid in this manner suffer, however, by the necessity to provide generally complicated and correspondingly expensive devices, which are easily subjected to failure, in order to obtain inside of the whorl a perfectly operating holding device.
  • An abutment member which is normally in the abutting position, is moved merely by lowering of the upper portion of the spindle into a lowered position, at the same time overcoming a spring force which retains the latter in normal positon, so that upon a following upward movement of the spindle in the direction of removing the upper portion from the lower portion of the spindle, a position is achieved wherein the upper portion may slide over an abutment member which the upward movement.
  • FIGURE 1 is a front elevation of a spindle, designed in accordance with the present invention, and partly in section, shown in normal operative position;
  • FIG. 2 is a section along the lines 2-2o-f FIG. 1;
  • FIG. 3 is a front elevation similar to that shown in FIG. 1, however, in a position in which the whorl has been lowered and indicating the mounting of the spring on the locking ring;
  • FIG. 4 is a section similar to that of FIG. 3 indicating the passing of the spring on the flange serving as an abutment
  • FIG. 5 is a section of the spring ring indicating the resilient tongues.
  • the spindle shown by example only, comprises a so-called centering tube mounting which is, however, not the subject matter of the present invention.
  • the known foot thrust journal for the spindle shaft 2 In the lower part of the spindle housing 1 is disposed the known foot thrust journal for the spindle shaft 2.
  • the foot thrust journal 3 is pressed against the inner shoulder 4 of the bearing sleeve 6 by means of the pressure spring 5 constituting a resilient member which engages the lower end of the bearing sleeve, whereby the normal position of height of the spindle shaft 2 is determined within the spindle housing 1.
  • the abutment sleeve 7 is mounted on the closure disc 13 of the bearing sleeve 6, which abutment sleeve 7 has at its upper edge a flange 8, the upper edge of which is chamfered.
  • a driving ring 9 which has some radial play, is mounted on the abutment sleeve 7 prior to its mounting onto the closure disc 13, which driving ring 9 is easily axially movable between the upper edge of the bearing sleeve 6 and the lower edge of the flange 8 and is normally disposed on the bearing sleeve 6 in a position shown in FIG. 1.
  • a horizontally disposed inner groove 11 is arranged within the whorl 10, the groove 11 receiving a slotted spring ring 12 which may consist of a suitable artificial material, the lower inner edge of the ring 12 being slightly chamfered.
  • the spring 12 may be equipped with resillent tongues 12 (FIG. 5) which are upwardly directed and have a slight inwardly directed resilient effect, which tongues may engage the flange 8 still better than the upper inner edge of the spring ring 12.
  • the measurements of the spring ring 12 are chosen in such a manner that on the one hand its total peripheral face is disposed inside of the groove 11, and on the other hand that it has such an inner diameter that it abuts normally on the underface of the flange 8 of the pirn or abutment sleeve 7.
  • the upper portion of the spindle shaft 2 is thus always secured against undesirable removal from the spindle housing 1 by means of the flange 8 of the abutment sleeve 7 which cannot be passed by the spring ring 12.
  • the upper portion of the spindle shaft 2 is pushed downwardly simultaneously compressing the helical spring 5, whereby the spring ring 12 rides on the driving ring 9, as particularly clearly shown in FIG. 3, and obtains a seat by friction.
  • the spring ring 12 which operated as abutment member, may ride now from the driving ring 9 over the flange 8 which formed until now the abutment member, since the outer portion of the driving ring 9 is now flush with the outer edge of the flange 8, or has even a slightly larger diameter.
  • the spring ring 12 n'des with simultaneous expansion over the flange 8 of the abutment sleeve 7, so that the spindle resumes again the operative position shown in FIG. 1.
  • the device as set forth-in claim 1, which includes a spindle housing and a whorl having an inner annular groove and surrounding said spindle and wherein said spring ring is received in said annular groove of said whorl, a bearing sleeve disposed in said spindle housing and having a closure disc, said flange of said abutment sleeve having a chamfered upper edge formation of said flange and said spring ring having a chamfered lower edge formation, and the outer face of said driving membeibeing substantially flush with the periphery of said flange of said abutment sleeve, a helical spring member disposed'at the bottom "of said spindle housing and retaining said spindle in normal position, and upon lowering of said spindle, said spring ring rides over said flange, due to said chamfered upper edge formation of said flange and said chamfered lower edge formation of said spring ring.
