Definitions

  • My invention relates to a method of transferring stitches from one needle to another in knitting machines, or to another loop-receiving instrument, whereby pattern or design effects by.
  • transferring is from one needle to another but other forms of transfer instruments may be used.
  • FIG. 1 is a front elevation of the form of transfer needle which I prefer to use with my invention, a cooperating needle or other loop-receiving instrument and also two positions of yarn loops (relative to the transfer needle) being indicated therein as well.
  • Fig. 2 is a side elevation of the matter of Fig. 1.
  • the needle 5 is a sliding latch needle, such as may be used in the cylinder of a circular knitting machine.
  • the instrument to receive loops drawn by the needle 5, as and when desired, is indicated diagrammatically at 8; this instrument may be a dial needle of the sliding latch type as will be understood.
  • a transfer clip 24, so called, is provided at and bulges from one side of the needle 5 as will be understood from prior practices; preferably the clip is attached to and carried by the needle at an appropriate distance below the needle hook as will be understood, but that is not entirely essential.
  • the end of the clip nearer the needle hook is free (unattached to the needle), and usually a depression 55 is provided in the side of the needle 5 in which this free pointed end 55 of the clip lies normally; the purpose of this is to permit the end 56 of the clip to pass readily into a loop 51 hanging on the needle as the clip is raised toward transferring position.
  • the instrument may be a conventional form of clip-type transfer device; the additional matter hereafter with respect to the needle 5 is illustrative of the type of device I prefer to use with my present invention.
  • the needle 5 is provided with a projection 58 to enter the loop prior to the passing into the loop of that portion of the clip which is farthest separated from the needle side; this projection extends forwardly, and is inclined forwardly and downwardly in such a manner as to draw out a loop 51 on the needle as the pro- J'ection is thrust upwardly into the loop, drawing it out in a direction directly'away from the edge of the fabric.
  • the projection 58 has a thickness not substantially greater than the thickness of the needle (and may have a thickness much less than the thickness of the needle as shown in the drawing), and the projection extends forwardly to such a distance that the greatest circumscribing perimeter around the projection is greater than the perimeter of a loop as drawn initially by the needle hook.
  • circumscribing perimeter it will be understood that I mean the perimeter as measured by the length of a thread necessary to circumscribe or enclose the projection and passing around the back of the needle.
  • theprojection 58 is an integral part of the needle-and-clip combination, and preferably is a projection from the forward edge of the needle as illustrated.
  • the clip may be shaped to somewhat extend the forward and downward incline of the projection as it were, as the clip departs from the needle side; this is shown in Fig. 2 immediately below the end 56 of the clip.
  • the forward edge of the clip is located further forward than the part of the forward edge of the needle which is adjacent thereto, at its maximum this difference preferably being as considerable as reasonably possible, as illustrated just above the shoulder or vnotch 6! on the clip in Fig.
  • a notch or shoulder 60 is preferably provided to receive the loop at some distance from the clip, that is to say, adjacent the needle,
  • is provided on the forward edge of the clip; preferably both such notches are provided.
  • on the clip against which the loop rests (or this part of the clip edge, if no shoulder is provided here) also is located further forward than the adjacent forward edge of the needle (Fig. 2) so that at this,
  • the needle In transferring a loop from the transfer in strument 5, the needle is moved through the loop to place the loop back of (e. g. below) the needle hook; in the case of latch needles, the latch is passed completely through the loop (Figs. 1 and 2).
  • the projection 58 is moved into the loop 51; as this projection moves into the loop it acts on the loop lengthwise of the loop, and this lengthwise draft on a loop, initially drawn by the needle too small to pass over (circumscribe) the projection, causes additional yarn to be drawn from the adjacent loop or loops and delivered into the loop to be transferred, whereby the latter loop is enlarged with the minimum effort and accordingly minimum of strain on the yarn.
  • the clip 24 is then moved into the loop (or passed further into it), and any continuation of the incline on the projection 58 that may be provided by the clip may act to draw out the loop 51 still further in a more or less lengthwise direction.
  • Continued movement of the clip passes the bulge of the clip into or further into the 1001),:
  • the steps shoulder or shoulders tend to place the leg 62 at which consist of placing the loop back of the needle hook in position to be cast off over the hook, then enlarging the loop by carrying the end of the loop forwardly and thereby drawing into the loop yarn from an adjacent loop or loops, and thereafter swinging one leg of the loop away from the adjacent side of the needle and swinging the forward end of the opposite leg of the loop across the needle to open the loop to admit the loopreceiving instrument.
