  • This invention relates to a new and useful improvement in a method of knitting on knitting machines of the circular, independent needle type and to the fabric produced by that method.
  • the method may be performed and the fabric produced on various kinds of knitting machines of the circular type, the well-known Banner machine is peculiarly suited for the purpose and, consequently, it has been selected for purposes of illustration and description herein.
  • Fig. 1 is a plan view of a part of a circular
  • Fig. 4 is an isometric view illustrating a number of the needles and sinkers and the manner in which the leg and instep yarn is manipulated by them; a
  • Fig. 5 is a similar view relating to the drawing and knitting of the yarn of the high splice, heel, sole and toe portions of a stocking having a split foot;
  • Figs. 6 and 7 are diagrammatic views of a needle and sinker illustrating the manner in which the leg and instep yarn is drawn in accordance with this invention
  • Figs. 8 and 9 are similar views illustrating the manner in which the yarn is drawn for the high splice, heel, sole and toe portions;
  • Fig. 10 is a view complementary to Figs. 6 and 7, and 8 and 9 illustrating a further step in the knitting operation;
  • Figs. 11, 12 and 13 are diagrammatic views of a needle illustrating different steps in knitting the leg and instep;
  • Figs. 14:, 15 and 16' are similar views illustrating steps in the knitting of the high splice, heel, sole and toe;
  • Figs. 17, 18 and 19 are views of a needle and two adjacent sinkers further illustrating the method of knitting the leg and instep;
  • Figs. 20 and 21 are similar views further illustrating the knitting of the high splice, heel, sole and toe;
  • Fig. 22 is a view of a sock or half-hose produced by the method of this invention.
  • Fig. 23 is a view of a ladys stocking also produced by this invention.
  • Figs. 24 and 25 are accurate reproductions of enlarged projections of actual split fabric produced respectively by the method of this invention and by the usual method showing the improvement obtained.
  • the knitting machine in general is provided with the usual cylinder 1, needles 2, yarn levers 3 and 4 carrier ring 5 and sinker cap 6 to which are attached the usual cams l, 8 and 9 for controlling the sinkers in the knitting of the high splice, heel, sole and toe portions of a split foot stocking.
  • the usual cams l, 8 and 9 for controlling the sinkers in the knitting of the high splice, heel, sole and toe portions of a split foot stocking.
  • On the auxiliary side of the machine there is another yarn lever ID for feeding the yarn from which the legand instep are knit.
  • side sinker cams H and I2 and center sinker cam l3 for controlling the sinkers in the knitting of this yarn.
  • the method of this invention follows the usual practice in the production of a split foot stocking. That is to say, the
  • the machine is raised out of operative leg is knitted by straight-a-way rotary knitting
  • the remainder of the stocking beginning at the top of the high splice is produced by reciprocatory knitting, part of the needles being utilized to knit the instep from the same yarn ployed in the leg and part of the needles being used to knit the high splice, heel, sole and toe portions from another yarn or yarns.
  • the margins of the instep and adjacent portions are, of course, interknitted to form suture seams.
  • suture seams While the structure of these suture seams may be varied, I prefer the structure shown in Patent #1,673,766 to Gagne, in which in one course of each side of the stocking there is a ,loop and a partial loop of one yarn interknit with a single loop of the other yarn, because of its strength and extremely attractive appearance.
  • leg and instep are 'to be knitted of the same yarn and the knitting of the high splice, heel, sole and toe portions of a split foot stocking is customarily performed on the main side of the machine, the auxiliary side indicated by the yarn main feeding station.
  • sinker cam I2 is provided with a point I6 which causes the sinkers to move inwardly sooner and further than usual so that the yarn I5 is drawn and measured over the backs of the sinkers I! as shown in Figs. 4, 6 and 7 instead of in the throats as shown in Figs. 5, 8 and 9.
  • center sinker cam 9 the loops will pass from the backs of the sinkers over the tops of the nibs into the throats as illustrated in Figs. 17
  • the needle loops which ordinarily hang rather loosely upon the needle shanks as shown in Fig. 15 because they have been previously riding upon the latches as shown in Fig. 14, are drawn snugly around the needle shanks as shown in Fig. 12 when the sinkers are retracted to cause the adjacent sinker loops to pass over their nibs. This tends to equalize the size of the needle loops and, consequently, the size of the adjacent sinker loops.
  • the needle loops are cast oif although they are necessarily stretched somewhat because they must pass over the latches, all of them will be stretched substantially to the same degree because they have been previously brought to the same size around the shanks of the needles as above described.
  • the leg of the stocking may be made of two yarns knitted simultaneously, one at the main side-and one at the, auxiliary side of the machine. .
  • This' is illustrated by Fig. 2 in which it is assumed that yarn lever 4 has been moved into feeding position to feed a yarn 2
  • must also be drawn and knitted in the same way at the same time. To do this yarn 2
  • a flopper cam 23 is provided having point '24 corresponding to point l6 of cam I2 which when the cam is swung in will move the sinkers in sooner and further than they would be moved by cam 8.
  • Mechanism for operating such a flopper cam is well-known and requires no description here.
  • is trans ferred from the backs of the sinkers over the nibs to the throats when the sinkers-are retracted by center sinker cam I3 on the auxiliary side and are-finally cast off at IE on the auxiliary side. By feeding and knitting yarns simultaneously on opposite side'of the machine the time required for knitting the leg is cut in half.
  • both yarns are drawn over the backs of the sinkers and subsequently caused to pass over the nibs into the throats and the new loops are cast off by the engagement of the sinkers with the previously formed loops all exactly as described before. In this way the time required for knitting the leg of the stocking is cut in half and the described improvements in the fabric obtained.
  • the yarn I4 at the main side will be drawnin the oldmanner in the throats of the sinkers by virtue of the usual sinker cams 1 and 8 to produce fabric of the usual type in-the usual way in the high splice, .heel, sole and toe (Figs. 5, 8, 9, 14-16, 20, 21).
  • the two types of fabric will, of course, be interlinked at adjacent edges by sutures preferably of the character already ment oned and illustrated at 28 and 29 in Figs. 22 and 23 respectively and any of the other features usually found in high splice, split foot hosiery for men or ladies may be included such, for example, as an automatically turned welt 30, a pointed high heel 3
  • the manner in which these features are made is well-known and needs no further description.
  • Figs. 24 and 25 The improvement insplit fabric obtained by following the method of 'this invention in reciprocatory knitting is shown in Figs. 24 and 25.
  • Fig. 24 is an accurate reproduction of an actual enlargement of actual fabric knitted in the usual way in which both yarns are drawn in the throats of the sinkers.
  • the washboard eiTect resulting from the tilting of the loops of one course 35 in one direction and of the next course 36 in the other direction is clearly evident as is the effect of these irregularities upon the sharpness of outline of the wales. Also many of the individual loops such as 3'! are not only tilted but unsymmetrical which further impairs the appearance of the fabric.
  • Fig. 25 is a similar accurate reproduction of a piece of split fabric knitted by the new method in which the leg and instep yarn is drawn over the backs of the sinkers. Although traces of the washboard effect may remain, the great improvement obtained is clearly evident. The loops are much straighter, more symmetrical and of more uniform size. Consequently, the wales are more sharply defined and the general appearance of the fabric is far superior to that of the old.
  • stocking as used herein is to be understood as including the article as it is removed from the knitting machine before the toe opening is closed as well as the completely finished article.
  • a method of knitting split fabric upon a circular, independent needle, knitting machine which consists of simultaneously knitting upon two groups of needles with individual yarns, one yarn being drawn'over the backs of thesinkers and through the needle loops ofthe previous course, the previously formed needle loops being cast off by the sinkers acting upon the correspondingsinker loops only, and ':causing the newly drawn sinker loops to pass from the backs ,toithe throats of the sinkers'over the tops of thenibs.
