Definitions

  • This invention relates to the art of spool carrier devices that are used in connection with braiding machines and has particular reference to an improved type of spool carrier that has tension adjusting properties that permit a wider range of more efiicient use.
  • one such adjustment device may be used for a wide range of tension requirements, while the other adjustment means may be used to bring adjacent carriers into tension conformity with each other.
  • FIGURE 1 is a perspective View of the improved wire braider carrier and showing the braiding thread being wound therearound for emission under tension.
  • FIGURE 2 is a longitudinal section taken on the lines 2-2 of FIGURE 1.
  • FIGURE 3 is a longitudinal section similar to FIGURE 2, but showing the position of the component parts when maximum tension has been built up in the thread.
  • FIGURE 4 is an elevational view taken substantially on the lines 4-4 of FIGURE 1 and indicating the position of certain component parts in full and chain dotted lines.
  • FIGURE 5 is a section taken on the lines 55 of FIGURE 4.
  • FIGURE 6 is a section taken on the lines 6-6 of FIG- URE l and being slightly enlarged for clarity.
  • FIGURE 7 is a perspective view of the carrier with the spool removed.
  • the improved wire braider carrier generally designated by the numeral 16 includes a support base 11 that is adapted to be mounted on existing braiding decks that will accommodate several such units of the type herein being described, with these units moving through an appropirate cross over path of movement that eflectuates braiding in known fashion.
  • the base 11 serves as a support for the various elements of the individual carrier 10, and to this end the same includes a pair of projecting bosses 13 and 14, with the boss 13 serving to support a spool or bobbin 15 of wound thread material T, while the boss member 14 supports an elongate tensioning mechanism 16 that projects from base 11 in substantial parallelism with the spool 15. In this fashion, and as shown in FIGURE 1, thread T, upon being unwound and passed over the guide elements of the tensioning mechanism 16 will emit longitudinally of the unit 13 through the eyelet 17.
  • FIGURES 1, 4, 5 and 7 of the drawings With reference to the structure by which the spool or bobbin 15 is mounted on the boss member 13, reference is first made to FIGURES 1, 4, 5 and 7 of the drawings.
  • the spool 15 is, in actual fact, journalled around a shaft member 20 that projects from the boss member 13 for this purpose.
  • a swing clip 21 is received in a slot Zita that is provided at the projecting end of the shaft 20, with the clip 21 having bifurcated legs 21a and 21b that are provided with slots that are received around a pin member 22. In this fashion upon pulling of the clip 21 to one extreme end portion, the same can be pivoted around the pin 22 so as to permit withdrawal or insertion of the spool member 15 with respect to shaft 2%.
  • the spool member 15 is provided with the usual core sleeve that concentrically surrounds the just described shaft 20 and extends between the axial ends of spool 15.
  • One such spool end has provided thereon a plurality of ratchet teeth 23, 23 that are designed for engagement with certain ratchet or pawl means that will now be described.
  • the ratchet means are shown as including a flat pawl member 30 that is pivoted to a flat surface 14a of the boss member 14 by mounting the same around a transversely extending pin 31, with the pin 31 being retained in position by split ring clip 31a and further preferably being integrally connected to the pawl member 33 so as to be movable therewith as will be described (see FIGURE 5).
  • the pawl member 39- further includes divergent projecting arms 32 and 33, with arm 32 being disposed for engagement between the ratchet teeth 23, 23, while arm 33 is engageable with certain cam means 40, as will be hereinafter described.
  • boss member 14 supports the tensioning mechanism 16 for controlling emission of the thread T, and to this end the boss member 14 is provided with a bore 14b (see FIGURES 2 and 3) within which is seated an elongate tubular member 34, with this tubular member 34 projecting from support base 11 in parallel with the shaft 20. Additionally, a shaft 35 (FIGURES 1 and 7) also projects from the boss 14 for supporting a guide roller 36, with the shaft 35 being offset, as shown in FIGURE l, for efiectuating proper location of the guide roller 36.
  • the pin 31 is journalled in the bore 14b and, accordingly, for the purpose of securing the tube 34 in place, the pin 31 also passes through an appropriate opening 34a that is provided in the lower end of the tube 34, with the pin 31 being retained in place by the split ring clip 31a.
  • the tube 34 further includes diametrically opposed slots 41 and 42 that are elongate in nature and that extend longitudinally of the tube 34 for purposes that will be described.
  • a further slot 43 extends inwardly from the projecting end 34b of the tube member 34, with this slot serving as a guide housing for the movable control guide element 45. It accordingly follows that the slot 43 will cause the end 34b of the tube 34 to be split, with this split end being en circled by ring 38 which is held against axial shifting on tube 34 by split lock rings 38a, 38a.
  • the ring 38 supports both an idler roll 39 and the previously described eyelet 17, with these components being best illustrated in FIGURE 1 of the drawmgs.
  • the movable control guide that has been indicated by the numeral 45, it will be first noted that the same is intended to shift longitudinally of the tube 34 in accordance with the tension applied to the emitting thread T, and to this end the pulley element thereof (46) is shown mounted on a block 47 that is received between the opposed walls of slot 43, with block 47 being keyed or otherwise secured to an apertured shaft 50 that is concentrically disposed interiorly of tube 34 and in encircling relationship to shaft 51 (see FIGURES 2, 3 and 6).
  • the elongate shaft 51 further has a threaded end 510 that receives a nut 52 for the purpose of providing adjustment in the extent of lost motion travel, as will now be described.
  • the opposed end 511) of the shaft 51 is shown fixed in known manner to an auxiliary sliding shaft 54, with this shaft 54 having a transverse opening 54a therethrough that permits the same to be journaled about a transversely extending pin member 55 that extends through the opposed slots 41 and 42, as clearly shown in FIGURES 2 and 3 of the drawings.
  • a ring member 56 is shown concentrically encircling the tube 34 and is adapted to receive the opposed ends of pin 55 so that shaft 51 and 54, pin 55 and ring 56 will move in unison relatively of tube 34.
  • a lifting rod 56a (FIGURE 1) can be provided on ring 56 for manual shifting of pawl 30 so as to permit playing out of thread during initial threading.
  • a stop ring 57 is shown encircling the tube 34, with ring 57 serving as a seat for one end of a spring 58, while the opposite end of spring 58 is seated against an axial end of the ring member 56 as shown in FIGURES 2 and 3.
  • the ring 56 and the parts associated therewith will normally be urged to the position of FIGURE 2 by the spring 58, with movement in this direction being limited by engagement of pin 55 with the left hand end of slots 41 and 42.
  • a cam block 59 is shown secured to one axial end of pin 55, with this cam block 59 being provided With a cross slot 59a (see FIG- URE 4) that is designed to receive the previously described cam arm 33.
  • shifting of the ring 56 axially of tube 34 will cause rotation of the pawl member 30 so as to permit disengagement of the arm 32 with teeth 23, 23, with the movement of ring 56 between the full and chain dotted line positions of FIGURE 4 effectuating such pivoting of the pawl plate 30.
  • the tube 34 also receives an internally presented spring member 60 that encircles the projecting end of shaft 51 and has one end thereof that seats against the end 50a of shaft 50. The remaining end of this spring 60 is shown seated against a cap member 61 that is in threaded engagement with threads 340 that are provided in the open end of the tube 34.
  • This arrangement of component parts permits the tension in spring 60 to be adjusted upon rotation of cap 61 as by positioning a screw driver in the turning slot 61a thereof.
