Definitions

  • This invention relat'es to a yarn building motion for ring doublingmachin'es whereby all types of ring doubling bobbins can be built using the same building motion with very little alteration, that is to say a parallel build can be obtained on a double flanged doubler bobbin, a long lift build can be obtained with a short taper at' the topon a doubler bobbin with a small top flange and avariable long lift build can be produced with a longer taper at the top on a single flanged bobbin and all these builds can be obtained without. the use of heart cams.
  • a regular lifting and lowering motion is imparted to the builder rail by a lifter shaft which extends throughout the length of the machine and has fixed on it bosses fromwhich are suspended flexible connections which are attached to lifter rods and pass over saidbosses carrying weights which balance the builder rail and itsattendant parts and reduce the torque on the lifter shafttoraise and lower such rails, the said lifter shaft being driven.
  • a lifter shaft which extends throughout the length of the machine and has fixed on it bosses fromwhich are suspended flexible connections which are attached to lifter rods and pass over saidbosses carrying weights which balance the builder rail and itsattendant parts and reduce the torque on the lifter shafttoraise and lower such rails, the said lifter shaft being driven.
  • reversing mechanism in combination with a tripmotion for varying the angle of rotation of the lifter shaft, means being, also provided for building abobbin with or withouta taper top and for altering the length and shape of the taper.
  • Fig. 1 is an end section of part of a doubling frame building motion constructedin accordance with this-invention.
  • Fig. 2 is; a view of a reversing mechanism which is used in combination withlthe mechanismrshown in Fig 1;
  • Figs. 3 and 4 are detached views of taperingmechanism which can be used inconjunction with themechanism.
  • each lifter rodrB Fixed tothebottomof each lifter rodrB is a bracket to-whichis attached the lower end of a chain C, the. upper end of which passes over and is fastened to a boss E fixed on aliiter shaft'l which extends throughoutthe length of the m'a' chine at each side and is supported in brackets P which are fixed to the framing F
  • A' balance weight C is suspended from each of the chains C to balance the lifter rods and builder rails and attendant parts and reduce the torque on the lifter shafts to raise and lower such rails.
  • The, lifter shafts may be driven from the usual frame-end gearing by, a change. worm G, 'Fig. .2,,meshing with a change worm wheel" H fixed on the upper end of ashort upr'ight sl-iaft on the lower end of which'is fixed a bevel pinion J.
  • This pinion is situated between two reversing" bevel Wheels K, K which may be s-lidably keyed ona cross shaft-L on'one end" of which is fixed a right hand'worm M and onthe other end is fixed a left hand worm M which mesh with corresponding wormwheels N N fixed' on the" lifter shafts F, F so that such shafts are driven in opposite directions'and the builderrails A at either side of the frame rise and-'fall together.
  • This lever is connected by" alinlr Qto a centrally disposed tail'pieceon a pivoted catch-plate E which is held in either of two positions whilst one or other of the reversing bevel wheels isin gear with the bevel pinion" by means of two pivoted catches R, R and'two-adjustable stops P P
  • the pivoted c'atchplate 3? may be formed with twonotches P P adapted to be engaged'by'oneor other of thetwopivoted catches and have the amount of-its" movement controlledb'y the two adjustable stops.
  • apinion T Fixed on one of the lifter shafts is apinion T whichgears' with a rack-U on an upright rodthat'is'sli-da-ble in be'arings and may be'formed at its upper end with a slot to receive one end of a two-armed tripping lever V that is fulcrummed vertically above the pivot of'the' catch plate; as shown at V Attached to'this tripping lever at opposite sidesof its fulcrum andat' equal distances there'- from' are two adjustable: hooksor eye bolts X; X each of which is connected through a lost mo-' tion device which may consistof two chain lin'ks X 'to a head X on thelupper' end ofa rod that passes freely'through a hole in a?
  • the length and the relative position of the movement of the ring rails can be adjusted by setting the position of the tripping screws, and the amount of play that can take place in this portion of the mechanism can be adjusted by setting the stops which control the amount of movement of the pivoted catch plate.
  • the building motion described will build a bobbin without a taper top and in order to build a bobbin with a taper top the upper end of the rack rod is provided with a fitting U containing a long slot U in which the end of the trip lever V enters and this fitting carries a shaft U which extends across the slot and is rotatable. Fixed on such shaft is an eccentric U which is situated within the slot at some distance below the lever and fixed on the shaft outside the slot is a ratchet wheel U that operates in conjunction with a pawl U formed with a tail piece U carrying an adjustable stop U that is adapted to rest on a part Y of the machine frame.
  • a part of the eccentric comes in contact with a rounded portion on the underside of the tripping lever V and lifts that end of the latter, the length of stroke of the builder rail bein determined by the part of the eccentric which comes in contact with the rounded projection and during this movement the pawl is disengaged from the ratchet Wheel by the weight of its tail piece and the adjustable stop, and to prevent unwanted rotation of the ratchet wheel when the pawl is out of engagement with it the ratchet wheel is provided with a check device which may consist of a boss U slidably keyed on the shaft U and having a serrated face U that is pressed against the corresponding face on the side of the fitting by means of a spring U With this arrangement each time the rack is approaching and arriving at the bottom of its stroke the pawl is brought into engagement with .one of the teeth on the ratchet wheel by the adjustable stop screw coming in contact with the part of the machine frame and turns the ratchet wheel through the space of one tooth
  • the length and shape of the taper on the bobbin can be varied by altering the shape of the eccentric or cam, and for a parallel bobbin, the cam and pawl may be removed and a concentric boss put in place of the cam.
  • the building motion is, therefore, simply adapted for use with double-flange bobbins, bobbins with a small flange at the top, and bobbins with a tapered top, and a flange only at the base.
  • the adjustments, as noted above, are simple, the adjustment for length and relative position of the lift being particularly simple.
  • the yarn building motion can also be employed for building yarn into cops or bobbins in spinning, twisting and like machines.
