Description

Fig. 3 illustrates the form which this suture assumes when the sole is widened as in portion 5 of Fig. 1. 'Ihis is knit as follows: Starting with course `E which is knit from right to left the sole is knit by the short butt group of needles at the main knitting cams to the loop I1. When the next course F is knit from left to right, the sole yarn is knit through loop I1 into loop I8. Simultaneously, the corresponding instep portion is being of needles at the auxiliary knitting cams but before needle I9 by which loop I8 was knit reaches the auxiliary knitting cams, it is raised so that it will function as a long butt needle and knit loop 20 of the instep yarn through loop I8 of the sole yarn.

At the end of this course F needle I9 is raised again into the long butt group and knitsv loop 2l of the instep yarn through loop 20 also of that yarn during the next course G of knitting from right to left. Before the main knitting cams are reached by needle I9, it is lowered vinto the short Ibutt group again and4 along with the adjacent needle 22 so that they knit loops 23 and 24 of the sole yarn through loops 2| and 25 of the instep yarn. The sole fabric has now been widened to the extent of one wale.

The cycle above described is now repeated beginning with course I-I on needles 22 and 4I and so on for the requisite number of times to produce the widening suture 5. In this section of the suture the characteristic referred to in relation to Fig. 2 persists, i. e., in the wale nearest the instep portion each of the two yarns of which the foot is composed is knitted through itself in alternation.

The portion 4 of the suture where the sole is narrowed may be produced in the following way. Referring to Fig. 4 and starting for convenience with the knitting of the sole yarn from right to left in course I, this knitting terminates with the loops 26 and 21. For the next course J which is knit from left to right a needle 28 is raised so that it takes this sole yarn around its shank but will not knit and needle 29 knits the sole yarn through loop 26 of itself into loop 30. At the auxiliary side of the machine at which the knitting of the instep is going on needle 28 is raised into the long butt group before it reaches the knitting cams so that it will knit loop 3| of the instep yarn through loop 21 of the sole yarn and also through the bight of the same yarn resulting from the fact that needle 28 did not knit, as above described. This is the last needle of the long butt group toknit in this course.

At the end of this course, needles 29 and 32 are raised so that when course K is knit from right to left needle 32 will knit the instep yarn through loop 33 of the sole yarn into loop 34 and needle 29 will knit the instep yarn through loop 30 of the sole yarn into loop 35. Before needles 29 and 32 reach the main knitting cams they are lowered so that at these cams they will knit loops 36 and 31 respectively of the sole yarn through loops 34 and 35 respectively of the instep yarn. Beginning with the next course L, the cycle is repeated. This course corresponds to knit by the long butt group l 4 of the split foot is illustrated by Fig. 5. This differs from that shown in Fig. 3 primarily in the wale adjacent the instep. The sole yarn is not knitted through itself in adjacent courses but is confined to single courses separated by two interknitted loops of the instep yarn. The manner of knitting described in connection with Fig. 3 may be followed with the exception that in course M corresponding to course F of Fig. 3, needle I9 is raised into the long butt group so that it takes "the sole yarn around its shank but does not knit course J. In this way, the sole may be narrowed to the desired extent. y

A modified suture for the widened portion 5 it with the result that needle I9 knits loop 20 of the instep yarn through loop I1 of the sole yarn and through the bight 38 of the sole yarn which, as just stated, was not knit by needle I9. Otherwise the knitting of this suture proceeds as described in connection with Fig. 3.

The suture of the high splice 39, if its sides are parallel as shown in Fig. 1, is the same as that of portion 3. The suture of portion 40 which is a rearward extension of portion 4 but is obtained by widening the sole instead of by narrowing as in portion 4 may have the form of either Fig. 3 or Fig. 5 the same as the other widened portion 5.A

This description has been` conned to a suture at one side of the stocking. Of course, it will be understood that there is a corresponding suture on the other side.

Reference has been made to short and long butt needles and short and long butt groups of needles. It is well-known that short butt needles are sometimes manipulated so that they function as long butt needles. It is also well known that needles having butts of intermediate length may also be used with long and short butt needles sometimes functioning as long butt needles and sometimes as short butt needles. 'Ihe reference to long and short butt groups of needles is not intended to define the length of the butts but the function of the needles at a given time regardless of the characteristics of their butts. The long butt group knits the instep yarn and the short butt group the sole yarn. The number of needles in each group depends upon the widths of the instep and sole and may vary as needles are transferred from one group to the other for widening and narrowing,

I claim:

A two wale split foot suture of which one Wale is composed of two courses of one yarn and two courses of another yarn in alternation and the other wale of two courses of the rst mentioned yarn in alternation with one course of the other yarn.
