Definitions

  • Our invention is concerned with cop winding machines in which the laying of the filament is effected with the aid of a traversing device, e. g. a grooved traverse drum, and according to the invention the shift referred to is produced by means of a feed mechanism comprising afeeler wheel which is engaged by the returning filament when for the time being maximum diameter is attained, and is thereby rotated.
  • a feed mechanism comprising afeeler wheel which is engaged by the returning filament when for the time being maximum diameter is attained, and is thereby rotated.
  • This feeler is intermittently moved out of contact with the package, and this movement is transmitted to the traverse drum or equivalent traverse device.
  • a gear wheel II on the spindle 3 engages a gear wheel II on a shaft I 2 driving a helically grooved traverse drum It.
  • the shaft I2 is flattened on one side.
  • the drum lgl has a single helical groove extending from near one end i to near the other, with short oppositely directed oppositely directed extensions of the groove afford by means of a frame.
  • the drum may have a single helical groove, giving controlled traverse in one direction only, with return traverse due brief guidance to the yarn when it becomes disengaged from the main groove at the end of the controlled traverse, and when it is about to enter the main groove at the end of the uncontrolled traverse, which is limited by the yarn meeting a guide or deflector I 5. 4
  • a boss at one end of the drum is engaged with a slotted extension II of a bracket Ii projecting from a slide l8 mounted on a spindle i9 and a guide bar It.
  • the spindle Ithas a screw thread on one side, and is flattened on the other side. It has rotatably mounted on it a feeler wheel 23, the hub of which is internally threaded to engage the threads of spindle H. The hub of the feeler can be pushed against the flat side of spindle I9, to
  • Figs. 1 and 2 represent one form of construc-'- tion, Fig. 1 being asectional elevation and Fig. 2 a section on the line ]III of Fig. 1

  • v Fig, 4 is a section on the line IV-IV of Fig. 3.
  • Figs. 5 and 6 are a side view and front view respectively, of a modified form of the builder unit and I Figs. '7 and 8 are similar views illustrating another modification.
  • a friction wheel disengage the threads of the hub from the threads of the spindle l9 and permit the feeler to be moved freely lengthwise of the spindle.
  • the hub of feeler wheel 23 is held in engagement with the threads of spindle is by a spring 21, which bears against a short arm 28 pivoted at It and formed with a ring portion surrounding the hub of wheel 23.
  • a finger 2'! serves as a handle for throwing arm 28 to the right (Fig. 2), to disengage the feeler wheel from the threads of spindle It, so that the bracket I8 can slide freely along the bar 20.
  • the spindle l9 and bar, 20 are connected with each other by bars 2L1: to form a small frame.
  • the bar .20 has revolubly mounted on it a collar 24, which can be fixed to it by means of a set screw 25.
  • the collar has an arm resting against an abutment 26, whereby the collar is restrained irom rotation.
  • a worm ll on the spindle l engages a worm wheel 4 l on a shaft 42, to which is fixed a cam 43
  • the bar 20 is axially movable, and a boss 44 at its left hand end (Fig. 1) is held against the cam 43 by a spring 45, so that during rotation of the cam the bar is reciprocated, and reciprocates the bracket it and the drum l3
  • the winding of a cop starts with the feeler.
  • the thread on the return of the traverse movement engages under feeler wheel 23 and rotates it a little, moving the frame it to the right by the amount of the thread diameter.
  • yoke 98a is slidably mounted by bearings til, @8,
  • the feeler wheel is carried by a shaft l5 rotatably mounted in a bearing it and carrying a spur gear as at its inner end.
  • the gear 83 meshes with a gear 3 3 revolubly mounted on spindle its.
  • the spindle is threaded on one side and flat on the other, like spindle it, except that the threads are on the opposite side of the spindle.
  • the hub of gear is internally threaded, to engage the threads of spindle its.
  • a bracket its Extending rigidly from bearing tilt of yoke its is a bracket its, which bears at its upperend a strap 8% surrounding a boss ti on traverse drum tile.
  • the traverse drum which, in this case hasa single-continuous groove, is fixed to a shaft Ma.
  • the shaft 52a which is rotatably and slidably mounted in bearings 82 and at, is keyed by flattened sides in the hub 36 of a gear its.
  • the shaft 52a can slide longitudinally in the hub St and a closed tube may be provided to cover its projecting end.
  • the cam 63 acts upon the end its aeea ssi of spindle Isa, to impart a supplementary move ment to the builder and traverse mechanisms.
  • the device operates in substantially the same manner as the one first described. 'The adjustment of the feeler wheel 23 with-respect to .the cop tube is accomplished by loosening screw 25a, then rocking box it on spindle flea.
  • the builder unit comprises a frame formed of a longi tudinal bar 98, cross bars at and 92, and bearings $8, at, 95 and 96.
  • the bearings 93 and 94 are slidably mounted upon a round rack bar i'tb,
  • the bearings 95 and 96 are slidably mounted upon a flattened shaft i227.
  • the rack bar tab can be mounted in the same way as the spindle ita of Fig. 3.
  • the shaft itb may be driven in the same way as the shaft E2 in Fig. l.
  • the bearing 96 has a tubular extension 9i? on which is rotatably mounted a feeler wheel 2%. This feeler wheel has a hub 5i extending to the left,
  • gear 53 is mounted to slide longitudinally on shaft t? and has an extended hub 99 keyed to the shaft ill by a key iiti.
  • the hub at bears a milled button 56, against which bears a spring till pressed inward by a cap tea on the end of shaft 9?.
  • the gear 53 meshes with rack bar Ebb and turning of the feeler wheel 23b moves the builder unit along the rack bar.
  • the milled button 5% can be pulled out against the action of spring iti to disengage gear 53 from rack bar 1%, permitting the builder unit to he slid along the rack bar.
  • the feeler wheel 2th and bearing 95 a traverse drum it is mounted on shaft 1112b and keyed to it by the flat sides of the shaft.
  • the feeler wheel 23b is cup-shaped and extends over the end of traverse drum it to the point where the helical groove of thetraverse drum terminates in one direction.
  • the contact rim of the feeler wheel is positioned to coincide with the change in direction of the traverse.
  • Figs. 7 and 8 show a modification in which the detector or feeler 230 is mounted on a vertical shaft and is arranged so that the returning filament is caught in the angle between the, surface of the cop cone and the side of the detector, thus ensuring that even with filaments of very high counts the wheel will be turned.
