Definitions

  • ABSTRACT A yarn bulking jet comprising a flat body and a door clamped together by fastener means, a longitudinal yarn passageway recessed in the surface of the body contiguous with the door, conduit means intersecting said yarn passageway at a shallow angle for injecting a fluid under pressure into said yarn passageway, said door having a slot recessed in the surface thereof contiguous to said body, said slot being parallel to and adjoining said yarn passageway, and a movable or removable insert conforming essentially to the dimensions of said slot and adapted to be inserted thereinto to substantially fill said slot, the jet being capable of aspirating at normal fluid pressure when said slot is open.
  • the present invention relates to apparatus for the treatment of synthetic yarn and more particularly to a jet useful for bulking such yarn.
  • a bulking jet which, although constructed in two or more pieces, need not be disassembled in order to string up the yarn and which will aspirate yarn into itself without reducing the pressure of the bulking fluid. Basically, this is'accomplished by providing the door of the jet with a slot which is parallel to and adjoins the yarn passageway in the body of the jet, which slot is filled with an insert after string-up.
  • the bulking jet of the invention comprises a flat body and a door clamped together by fastener means, a longitudinal yarn passageway recessed in the surface of said body contiguous with said door, conduit means intersecting said yarn passageway at a shallow angles for injecting a fluid under pressure into said yarn passageway, said door having recessed in its surface a slot parallel to and adjoining said yarn passageway, and an insert conforming essentially to the dimensions of said slot and adapted to be inserted thereinto to substantially fill said slot.
  • FIG. 1 is an exploded view in perspective of an entire jet according to one embodiment of the invention which includes a removable insert.
  • FIG. 2 is a plan view of the jet of FIG. 1 without the removable insert in place
  • FIG. 3 is a sectional view taken along line 3--3 of FIG. 2.
  • FIG. 4 is an exploded view in perspective of a jet according to another embodiment of the invention, while in the body and door, respectively.
  • the jet body has recessed on the surface thereof contiguous with the door 2 a yarn passageway 3 consisting of a semi-conical entry section 6, a bore 7 of square cross section, a throat 8 having a rectangular cross section larger than the bore 7, and an expansion chamber 9.
  • the door 2 is provided with a slot 11 recessed in the surface of the door contiguous to the jet body 1 and lying parallel to and adjoining the yarn passageway 3.
  • the slot 11 is slightly tapered, as shown in FIG. 2, and has a width such that the bulking fluid after traveling through a short section of conduits 5 can expand into slot 11 to create an aspirating effect.
  • FIG. 1 Also shown in FIG. 1 is a removable insert 16 consisting of an elongated tapered member 12, a head 13 and a wire handle 14.
  • the tapered member 12 is so shaped and sized as to be insertable into slot 11 and substantially fill the same.
  • the stringing up of the bulking jet of the invention is exceedingly simple.
  • the yarn is directed across the top of the jet by appropriate means such as an air aspirating gun.
  • the jet is made capable of aspirating by removing insert 16 to create slot 11.
  • the bulking fluid is then introduced at normal operating pressure.
  • slot 11 only partially covers fluid conduits 5, the fluid is directed downwardly thus causing the jet to aspirate.
  • the insert 16 is inserted into the slot 11 and the jet thereby converted into a bulking jet without changing the pressure of the bulking fluid.
  • the jet of this embodiment comprises a jet body 1 identical to the jet embodiment of FIG. 1 and a door 17 which arm secured together by means of nuts and bolts 15 and 15A through mated holes 10 and 103 in the body and door, respectively.
  • the door 17 in this embodiment is provided with grooves 18 and 19 and in its bottom and top surfaces, respectively, and a slot 20 in the face of the door abutting the jet body 1, with said slot 20 parallel ing and adjoining the yarn passageway 3.
  • the door 17 is provided with a threaded hole 21 into which is threaded a set screw 22 which has a handle 23 and a head 24.
  • insert. 25 consisting of vertical section 26 which is provided with recess 27, into which the head 24 of set screw 22 is engaged, and horizontal arms 28 and 28A which mate into grooves 18 and 19, respectively.
  • turning of the set screw 22 causes back and forth movement of insert 25. Consequently, when the set screw 22 is in its fully retracted position, insert 25 is withdrawn into slot 20 leaving open the portion of the slot adjacent yarn passageway 3. Conversely, when set screw 22 is rotated into its forwardmost position, insert 25 is caused to move forward into a position abutting the yarn passageway 3.
  • FIGS. 4, 5 and 6 The operation of the jet shown embodied in FIGS. 4, 5 and 6 is analogous to that of the jet embodied in FIGS. 1, 2 and 3. That is, when stringing up the yarn, the movable insert 25 is retracted. While the yarn is running across the top of the jet, the yarn is cut and its free end aspirated into the jet. Thereafter, insert 25 is moved forward into engagement with the body leaving only the yarn passageway as the opening through which the yarn travels.
  • a yarn bulking jet comprising a flat body and a door clamped together by fastener means, a longitudinal yarn passageway recessed in the surface of the body contiguous with the door, conduit means intersecting said yarn passageway at a shallow angle for injecting a fluid under pressure into said yarn passageway, said door having a slot recessed in the surface thereof contiguous to said body, said slot being parallel to and adjoining said yarn passageway, and a movable insert conforming essentially to the dimensions of said slot moveable to substantially fill said slot, the jet being capable of aspirating at normal fluid pressure when said slot is open.
