Definitions

  • ABSTRACT A pattern wheel for a circular knitting machine is provided with pivotally mounted jacks capable of beingmoved about their pivotal mountings between needle-actuating positions and non-actuating positions, the pattern wheel also being provided with means effective to prevent dislodgement of the jacks from their needle-actuating positions when disposed over the jacks and secured to the wheel.
  • the basic elements of a pattern wheel are a jack-retaining ring, needle-raising jacks to act on the butts of knitting needles and a cover to lock the jacks in place in the retaining ring.
  • the most common type of pattern wheel is assembled by manually inserting the jacks in selected slots formed in the retaining ring and then securing the cover to the retaining ring, the jacks being inserted only in those slots to be used in raising a needle and the other slots being left empty.
  • the manual insertion of jacks in a wheel has always been a time-consuming and costly operation, and is becoming even more so because of an increased demand for circular knitting machines having more feeds with a pattern wheel at each feed.
  • the pattern wheel of the invention comprises a jack-supporting ring which includes radially extending slots and jacks in such slots pivotally mounted for movement between needleactuating positions and non-actuating positions, and means securable over the supporting ring to hold down the jacks when in needle-actuating positions.
  • FIG. 1 is a sectional view of a cording to the invention.
  • FIG. 2 is an exploded perspective view of the pattern wheel showing a jack retaining ring and covers of the pattern wheel of the invention.
  • FIG. 3 is an enlarged fragmentary planar view of the retaining ring.
  • FIG. 4 is a perspective view showing a jack and supporting arm for use in the pattern wheel of the invention.
  • FIG. 5 is an exploded view of the jack and supporting arm of FIG. 4.
  • the pattern wheel of the invention may be seen as comprising a jack retaining ring 12 and covers 14 and 16.
  • the jack retaining ring includes a plurality of tapered teeth 18 and a plurality of radial slots 20 extending pattern wheels for circular knitting pattern wheel constructed acinto flared-out spaces 22 between the teeth.
  • An annular groove 24 is formed in the ring as shown.
  • a jack supporting arm 26 is mounted in each of the slots 20 of the jack retaining ring and connects at pin 29 with a jack 28.
  • Each jack 28 is pivotable on pin 29 about the arm 26 with which it connects, being movable between a needle-actuating position (Position A) wherein the trapezoidally free end of the jack occupies a space 22 and a position (Position 8) wherein the jack rests on top of the amt.
  • Each of the arms 26 includes a finger 30 which extends into the annular groove 31 to prevent radial movement of the arms and connected jacks.
  • the covers 14 and 16 fit over a boss 32 formed on the jack retaining ring and are securable to the plate by screws 34 and 36 respectively.
  • the cover 14 when secured to the jack retaining ring is effective to hold down arms 26 and so preventthe fingers 30 from being dislodged from annular groove 31.
  • Cover 16 when secured to the jack retaining ring, holds jacks which are in an open position (Position A) securely in place. As indicated, in the open position, the jacks 28 are engaged by annular surface 38 of the cover 16 and in the folded position (Position 8) the jacks are wholly within annular recess 40 formed in the cover 16.
  • the jacks of the pattern wheel are set with only the cover 14 in place, the normal procedure being to start with all jacks in open positions and then flipping over selected jacks either manually or with a suitable indexing device according to the intended use of the wheel, after which the cover 16 is secured to the jack retaining plate 12 to prevent dislodgement of the jacks from their desired positions.
  • the pattern wheel has a central bore 42 in which there is provided a sleeve 44 having a axial length slightly in excess of that of the bore and a stub shaft 46 having a foot 48 at one end.
  • the other end 50 of the shaft 46 is threaded to receive a nut 52 which may be tightened to affix the position of the foot 48 in a slot on a knitting machine and maintain the sleeve 44 stationary while the wheel is free to rotate on the sleeve.
  • the wheel can readily roll into the butts of cooperating knitting needles of a circular knitting machine and there is little likelihood of any interference between the needles and teeth of the wheel oecuring.
  • the teeth are tapered as shown it is possible to have the roots of the teeth of substantial thickness and yet provide substantial spacing at the periphery of the wheel to accommodate swedged ends 54 on the jacks 28.
  • Such swedged ends 54 offer a wide surface to the butts of needles which are to be lifted by the pattern wheel, the butts are prevented from slipping off the jacks prematurely and defects which would otherwise be produced in the fabric being knitted as well as possible damage to the wheel and needles are avoided.
  • a pattern wheel comprising a jack-supporting ring which includes a plurality of radially extending slots, a jack in each of at least some of said slots, anarm for each of the jacks and each of the jacks being pivotally mounted on its associated arm for movement between a needle-actuating position and a non-actuating position, each jack and associated arm being removable as a unit from a slot, means for holding each arm in a fixed position in the ring, and means for holding down the jacks which are in needle actuating position.
