STOCKING August A.

(Cl. 66-187) My invention relates to full-fashioned knit stockings and more particularly to a unitary stocking blank provided intermediately with a widened heel-forming portion. It is the object 2 the leg and ,anklerforming portion 9 of the blank is knit in any desired manner down to the course, A-A where widening for the heel is to begin. Beginning at course A—-A, a numberofstitches of my invention to produce a stocking blank 5 at the ends of certain subsequently» knit courses which can be knit completely on a single ?at are transferred outwardly, and the travel of the knitting machine and which when formed into thread carriers is increased at a rate correspond a- stocking will have a well-?tting heel of at ing to the rate of transfer so as to produce a tractive appearance. I gradual widening of the blank. As is well known, That portion of a stocking blank with which 10 the widening of a hosiery blank by the outward my invention is primarily concerned lies between transfer of stitches, even if each outward trans the leg-forming and foot-forming blank-portions fer is by only one needle, leaves in the fabric a and comprises three contiguous zones de?ned by small opening l0 adjacent each innermost trans the edges of the blank and by spaced courses of ferred stitch. The number of stitches transferred knit stitches. The ?rst of these zones in the 15 in each transfer course following course A—A is order of knitting is trapezoidal in shape and of gradually increasing width toward the second gradually increased, desirably at a rate such that the openings W in the fabric will be disposed in zone, the second zone is desirably of uniform a line extending obliquely inward of the blank. width; and the third zone is trapezoidal and of If desired, the holes I0 may be closed in any gradually decreasing width toward the foot-form 20 convenient manner, such, for example, as that ing portion of the blank. The ?rst zone is char set forth and described in U. S. Letters Patent acterized by the inclusion of longitudinally dis No. 2,330,683, granted September 28, 1943, on the tributed transfer courses ineach of which a group of‘ stitches, progressivelyv increasing in number application of Arthur J.

The third zone is 30 at the same rate as that obtaining between the characterized by its‘inclusion of transfer courses courses A——A and B-B, the travel of the thread in each of which a group of stitches at each end carriers is not increased.

The spliced courses A-A and 3-13 provides an increasing portion at each side of the blank at course A-—A circumferential elasticity as the instep line is extends inwardly beyond the innermost stitch approached; and the relatively large number of of the first set of outwardly transferred stitches. generally vertical wales at and below the lower Desirably, the number of spliced wales at course end of the line of openings ID add to the elas A—A is only slightly greater than the number ticity of the stocking longitudinally of the foot. of wales in which stitches are to be transferred These features all contribute to extending the outwardly at course A-A, and the number of range of foot-sizes and foot-shapes which a given wales including the splicing yarn is increased at a rate such as will maintain the inner edge of 10 stocking will ?t. the spliced portion generally parallel to and spaced inwardly from the line of openings I0. I prefer that the gradually widened spliced por tion attain its closest approach to the center-line I claim as my invention: 1. A ?at-knit hosiery blank the stitches of which are arranged in transverse courses and generally longitudinal wales, said blank having of the blank at or near the course B—B at which 15 a leg-forming portion, a foot-forming portion. widening of the blank terminates. ' and an intermediate portion, said intermediate The conformation of the blank and hence the portion being divided by longitudinally spaced shape of the ?nished stocking can, without de courses of stitches into a ?rst zone joining said parting from my invention, be varied widely, as leg-forming portion, a second zone joining the by varying the distance between the courses 20 first zone, and a third zone joining the second A-A, B—B, C-—C, and D-D, by varying the zone and said foot-forming portion, said ?rst and number of transferred stitches, and by varying second zones including a plurality of transfer the rate at which stitches are transferred. In courses in each of which a group of stitches at one procedure which I have followed to produce each end of the course are transferred outwardly a satisfactory stocking, 30 stitches are trans 25 to form obliquelyrextending wales, the number ferred outwardly for one needle at each end of of outwardly transferred stitches in transfer course A-A. The transfer points which e?ected the outward transfer are then moved inwardly . for two needles in preparation‘ for the next out courses of the ?rst and second zones progressively increasing throughout the ?rst zone and pro gressively decreasing throughout the second ward transfer, which occurs in the fourth course 30 zone, said third zone including a plurality of following course A--A_ This procedure is re transfer courses in each of which a group of peated at four-course intervals, accompanied by stitches at each end of the course are transferred increases in thread-carrier travel at the same inwardly, the number of stitches in the courses average rate, until twenty-eight outward trans fers have been made. The last of such transfers is made at course B—B, at. which point the width of the blank has been increased by twenty-eight of said intermediate blank-portion progressively increasing in the ?rst zone, being constant in the second zone, and decreasing in the third zone, whereby the width of the blank will progressively needles on each side and the number of outwardly increase throughout the ?rst zone, remain con transferred stitches at each side of the blank stant throughout the second zone, and progres 40 has been increased from 30 to 58. After the knit sively decrease throughout the third zone. ting of course 3-3, the outward transfer of 2. A ?at-knit hosiery blank the stitches of stitches at the sides of the, ‘blank is continued which are arranged in transverse courses and at the rate of one needle for every four courses, generally longitudinal wales, said blank hav but the travel of the thread carriers is not in ing a leg-forming portion, a foot-forming por creased and the transfer points are not moved 4. tion, and an intermediate portion, said inter inwardly of the blank between transfers. Course mediate portion being divided by longitudinally C—C, marking the end of the second zone, is spaced courses of stitches into a ?rst zone join reached after fourteen transfers; and following ing said leg-forming portion, a second zone join the last such transfer, the transfer points are ing the ?rst zone, and a third zone joining the moved outwardly in preparation for the first of second zone and said foot-forming portion, said ' the inward transfers which characterize the ?rst and second zones including a plurality of knitting of the third zone. That third zone, transfer courses in each of which a group of lying between courses C-C and D-—D, embodies stitches at each end of the course are transferred. 80 courses each fourth course of which is a trans outwardly to form obliquely extending wales, the fer course in which 20 stitches at each end of‘ ' number of outwardly transferred stitches in the course are transferred inwardly by two needles to effect narrowing in known manner. It is to be understood that the above speci?c example is illustrative only and that consider able variation therefrom may occur without de parting from my invention. The outward trans fer of stitches in the second zone can be elimi nated, or the second zone can be reduced to only a few courses in longitudinal extent or elimi nated altogether. When a blank widened intermediate its length as above described is seamed, the resulting stock ing has the characteristics illustrated in Fig. 2. transfer courses of the ?rst and second. zones progressively increasing throughout the ?rst zone, said third zone including a plurality of transfer courses in each of which a group of stitches at each end of the course are transferred inwardly, the number of stitches in the courses of said intermediate blank-portion progressively in creasing in the ?rst zone, being constant in the second zone, and decreasing in the third zone, whereby the width of the blank will progressively increase throughout the ?rst zone, remain con stant throughout the second zone, and progres sively decrease throughout the third zone. 3. The invention set forth in claim 2 with’the addition that the marginal portions of the blank are reinforced with splicing yarn, each reinforced number from course A—A to course B—B, and marginal portion beginning in the leg-forming the line of openings in curves downwardly and portion of the blank and continuing through said forwardly parallel to the adjacent edge of the spliced portion._ The progressive increase in the 75 intermediate portion into the foot-forming por The course B—-B is located at or near the instep line.
