Definitions

  • jet devices for texturing yarn are provided which can be quickly and simply adjusted as often as desired to a preset stringup position and back to a preset operating position.
  • means are also provided to facilitate accurate presetting to the optimum positions for different yarn treatments.
  • the invention is an improvement in yarn-texturing devices of the type having a hollow body member forming a fluid chamber, means for introducing fluid under pressure into the chamber, an exit nozzle from the chamber for fluid and yarn, and a yam-guiding tube extending through the chamber for supplying yarn to the nozzle for texturing; wherein the im provement comprises means for quickly adjusting the nozzle to preset positions relative to the tip of the yam-guiding tube.
  • the nozzle is threaded to the body member and stops are provided to limit the rotation, the nozzle being held in the chosen position by friction of the screw threads.
  • the nozzle is mounted in the body member with a sliding fit so that the nozzle can be pushed closer to the yam-guiding tube and will be returned to a preset operating position by a spring.
  • the nozzle can also be hcld'in operating position by fluid pressure alone, without the use of a spring.
  • This second embodiment can provide mounting of the nozzle for rotation to adjust the relative axial positions of the nozzle and yarn-guiding tube.
  • FIG. 1 illustrates one embodiment of the invention as applied to a conventional type of yarn-texturing device.
  • LII are three basic components: a hollow body member 1, a nozzle member 2 and a yarn-guiding tube 3.-The initial portion of the yarn tube is enlarged to fit snugly inside the body member, and is held in position by set screw 4. The subsequent portion of the yarn tube is spaced from theinside of the body member to form an annular chamber. and the terminal end of the yarn tube is within a funnel-shaped entrance of nozzle member 2. The annular chamber is supplied with fluid under pressure through passage ll.
  • the fluid passes around the yarn tube into the nozzle member and exits through nozzle passage I4.
  • the nozzle member is threaded onto the body member and may be rotated to adjust the position of the funnel-shaped entrance relative to the end of the yarn tube. Movement of the nozzle member is'limited by a projection 5 contacting stop screws 6 and 7 threaded into the outside of the body at the preset positions.
  • the projection S- may be a pin affixed in the outer edge of the nozzle member. Holes may be provided at various positions around the body member so that screws 6 and 7 may be moved to adjust the range of ,rotation of the nozzle member.
  • the pitch of the screw thread is selected to give the desired amount of axial movement within the limits of rotation permitted by the screws. Sufficient friction is provided between the nozzle member and the body to resist undesired rotational movement away from a given position.
  • FIGS. 2 and 3 illustrate an embodiment of the invention wherein the nozzle member 2 has a sliding fit in the body member 1 so that it can be pushed into the body to a stringup position and then returned to a preset operating position.
  • the nozzle member is also mounted for rotationwithin preset limits.
  • the body member has a cylindrical inner surface.
  • the nozzle member has a cylindrical outer portion which slides easily into the body but does not leak gas appreciably at the joint between the two. lnward motion of the nozzle member is limited by a collar 12 which overlaps the end of the body. Openings 15 are provided in the collar for stop screws 9 which are threaded into holes 16 in the body.
  • a spring 10 holds the nozzle member outward against the screws during operation. By pushing the nozzle into the body a suction is created through the yarn tube 3 which facilitates stringup. When released, the nozzle is returned to the limit of outward movement determined by the setting of the stop screws 9.
  • the openings 15 can be in the form of slots, as shown in FIG. 3, so that the nozzle can be rotated. This is of particular advantage when the passage 14 is axially offset in the nozzle as illustrated. Additional screws 9 may be provided to limit the extent of rotation as desired. The length of the slots can also be varied. I
  • the spring 10 is not essential when the fluid introduced through passage 11 has sufficient pressure to hold the nozzle outward in the operating position.
  • a variety of nozzles can be used instead of the one shown, which has a funnel-shaped converging section followed by a diverging section.
  • Other yarn tubes can also be used.
  • the yarn tube 3 shown in FIG. 2 has an enlarged initial portion, of greater length than the one shown in FIG. I, with a flat section 8 machined on one side for fluid to pass along that side only from the passage 11 to the annular chamber adjacent the tip of the yarn tube.
  • the jets of this invention may be adjusted, using measuring tools or setting fixtures, to assure that all jets used for a par ticular yarn type are fixed in the same dimensional positions to provide the same air flow conditions and that such settings can be repeated each time a particular type of yarn is to be run.
  • nozzle member 2 is moved inward as far as possible toward the needle 3.
  • the conical tip 17 of the yarn tube may be eccentric, or the yarn passage 13 may be eccentric within the nozzle entrance.
  • the passage 14 in the nozzle may also be asymmetric or eccentric.
  • One advantage of all jets of this invention lies in the reduced number of hand motions and time required to string up the apparatus. Such savings, multiplied by many texturingpositions and hours of operation, can result in substantial increases in operator productivity.
  • a jet When a jet is mounted on a texturing machine, an operator moves nozzle member 2 into strin'gup position, introduces the yarn into the funnel-shaped entrance to yarn tube 3, and catches the emerging yarn in the same operator proceeds immediately to string up further elements of the machinery.
  • An additional advantage of all jets of this invention is the ease with which an inventory of various sizes and types of interchangcable yarn .tubes and nozzle members designed for optimum processing of yarns of various denicrs and materials may be set to predetermined positions by means of measuring devices or setting fixtures.
  • An advantage of jets of this invention having an asymmetric or eccentric yarn tube is the ease and-precision with which the tube may be positioned in precise rotational relationship to the fluid passage 11, or to the direction in which the yam bends as it leaves the fluid stream abruptly near the jet exit, or to the rotational position of any asymmetric or eccentric feature of the nozzle member. ln case both the yarn tube and the nozzle have asymmetric or eccentric features, such features may be set in precise relationship to each other.
  • An improvement in yarn-texturing jet devices comprised of a hollow body member forming a'fluid chamber, means for introducing fluid under pressure into the chamber, an exit nozzle from the chamber for fluid and yarn, and a yarn-guiding tube extending through the body chamber for supplying yarn to the nozzle for texturing; wherein the improvement comprises a movable nozzle member mounted on said body member for movement from an operating position to a stringup position closer to the end of the yarn-guiding tube and for movement back to the operating position, and means for stopping movement of the nozzle member at a preset operating position.
  • a jet device as defined in claim '1' wherein the means for stopping movement of the nozzle member comprises adjustable stop members to preset operating positions for different yarns.
  • Ajet device as defined in claim 1 wherein the nozzle member comprises a portion sliding into the body member and a collar portion overlapping the end of the body member for stopping movement at the stringup position, and the means for stopping movement at the operating position comprises stop members projecting through openings in said collar portion and secured in the body member.
  • a jet device as defined in claim 4 comprising spring means for returning the nozzle member to the operating position after the nozzle member has been pushed into the stringup position in the body member.
