Assuming that the means which acts directly upon the desired or selected needles, moves them inward by a pushing action, such means or instrumentality is desirably. individual to each of the needles, and may be I made to engage the desired or selected gneedles at any suitable point along said needles.

  • Our invention may be applied to any type of independent needle knitting machine, but we have represented the same as applied to a circular hosiery knitting machine, and have selected for illustration a machine of the so-called Banner type and, without limiting our thereto, we will describe the preferred form or embodiment of our invention as applied to a machine of that type.

  • the needle cylinder is desirably of the revolving type, though obviously our invention is not limited in this respect. While any 55 suitable" provision may be made-for permitting the desired or selected needles to be moved inwardly, we preferably provide a slight bend in the needle stems, as indicated at l in Figs. 6 and 7, so as to render the needles sufficiently springy 7 for the purpose intended. Such bend is preferably provided in all the needles of the circle, and
  • the web holder bed ring is indicated at 8, and the cap ring is indicated at 9.
  • the sinkers or web holders are desirably all provided with ordinary upper nibs I 0 beneath which are the throats ll. Immediately below the throats II are the web holding edges l2 of the sinkers or web holders. In effecting normal plating the sinkers or web holders all act in the usual manner known to those skilled in the art, and which therefore need not be described in detail.

  • the sinkers or web holders are of the sliding ty'pe, although our invention is not limited in this respect, it being merely necessary that the sinkers or web holders be so web holders, and, excepting as herein described,

  • Such means is desirably cam means and while a singlecam may be employed for this purpose we desirably employ a plurality of cams which are so positioned that each will act only upon sinkers or web holders While in no sense limiting our to a plurality of cams, or to two cams if a plurality be employed, we have herein represented two special cams at 25, 26, shown most clearlyin Figs. 3, 6 and '7. Said cams are desirably placed one over the other and are herein represented as having a common pivot 21 in the cap ring 9.
  • the said cams are provided with tails 28, 29 extending beyond their pivots and adapted to be engaged by springs 30, 3
  • Said cams are provided with pins or projections 32, 33, to be engaged by means to be described for moving said cams inward at the proper time, thereby to cause them respectivelyto engage with the butts of those sinkers or web holders pertaining thereto.
  • the sinkers or web holders of the entire circular series are herein of the shapes or forms shown in Fig. 12.
  • 34 sinkers or web holders which have short butts 35 and which are devoid of lateral projection. Therefore reverse plating is not effected at any time upon the needles pertaining to the web. holders or sinkers 34.

  • sinkers or web holders provided with high butts 39.
  • the said sinkers or web holders 36 and 38 are provided with lateral formations or projections 48, and it will of course be understood that the web holders 36 and 38 may be distributed as desired throughout the entire circle. They may be inserted singly, if desired, but preferablyin' groups of atleast two, but their distribution and arrangement depend upon the pattern or design that is to be produced.

  • Each sinker or web holder 36 and 38 by reason of engagement of its lateral projection or formation 48 with the stem of its needle 4, causes the hook portion of the said needle to be slightly inward, so as to be slightly inside the-line of the circle of needles.
  • the amount of the inward I movement of such needles may vary under different conditions, but in fine gauge work an inward movement of about one sixty-fourth to one thirty-second of an inch has been found to be sufiicient. This, however, depends upon conditions and circumstances, and may be varied accordingly.
  • the hooks 5 of all the needles are the same. Herein we have shown them all as forward hooks.
  • the bend I in the shank of the needles need be merely enough to make them all springy so that the desired needles may be moved inward by the sinkers or web holders having a lateral projection 40.
  • By providing all the needles with the bend I it is merely necessary to take out web holders 34 or any of them and substitute web holders like 36 or 38 in order to efiect reverse plating at those needles.
  • the position of the lateral projections or formations 40 is such that said projections or formation's do not interfere with casting off; that is, when the throat of a sinker has moved in just far enough to cast off the lateral projection or formation 46 upon that sinker or web holder (if one be provided) is still pressing its needle in beyond the circle of needles to the maximum extent.
  • Such lateral projection or formation 40 first engages the stem of the needle at about the point 46 (see Fig. 4), and at the point 43 the said projection 40 has pushed its needle inward to the maximum. extent and the said needle remains in to the full extent for a distance which is about the space included by four or five of the sinkers or web holders when in the machine.
  • a bracket or standard 41 shown in Fig. 2 as located at the narrowing picker side of the machine there are mounted for sliding movement two bars 48, 49 of which the upper bar 48 engages the pin 33 'upon the cam 25 and the lower bar 49 engages the pin 32 upon the cam 26.
  • one or the other of the said cams 25, 26 is moved radially inward sufficiently for it to cause the sinkers or web holders whose butts are of the form or location to be engaged by such cam, to be so engaged, and thereupon to move the corresponding needles inward as already described.
  • Each bar 48, 49 is connected by a pin (not herein shown) to the proper one of two levers whose outer ends are forked and are respectively engaged by the upper reduced ends 50, 5
  • Said links as shown at their lower ends, are pivotally connected at 60, 6
  • the shape of the cams upon the drums 66 for controlling the levers 64, 63 depends upon the pattern and may be varied if desired.
  • the said cams should be such as to render the cams 25, 26 ineffective for reverse plating during heel and toe work, and the cams may be and preferably are of such shape as to provide both long and short vertical lines and also mere dots, as well as figured or pattern effects.
