Claims. (Cl. 662illi) This invention relates to new and improved weft knitted fabrics and methods of making the same, and more particularly to fabrics such as stockings or half-hose having clocking or other 5 efiects knitted therein by means of or including so-called wrap threads and wherein adjacent wales show threads having different colors or other characteristics.

In the drawings:

Fig. 1 is a view of one form of knitted fabric, the wrap or face threads being shown broken away in order to show the body yarn; and

Fig. 2 is a view of a modified form of knitted fabric, the wrap or face threads likewise being 16 shown broken away.

Referring to Fig. 1, the fabric is shown therein as being composed of a main or body yarn i, a wrap thread 2 of one color or characteristic, and a second wrap thread 3 of another color or characteristic', both threads 2 and 3 preferably being of a color or other characteristic different from the body yarn i.

The clock or other area includes courses il-it inclusive, course being shown as the last plain knitted course, i. e., the last course wherein all of the needles knit the body yarn 5. Immediately following the knitting of the course t all or the needles engage the yarn l and draw the same through the loops constituting the course 6, cer- 39 tain of the wales of which are indicated by the numerals ii, 52, i3, id, Hit, it, it, it, and i9, wales ii and is being plain wales, i. e., knitted throughout with yarn i only. Preferably, just prior to the needles, that knit the wales i2, i3, it, and is, engaging the yarn i, such needles are wrapped by means of the wrap thread 2 which wrapping may be accomplished in any suitable manner such as for example by a machine similar to that shown in the Lawson Pat- 48 cut No. 1,702,608, February 19, 1929 and more specifically disclosed in the patent Great Britain, No. 367,796, February 19, 1932. If the fabric be knit on a circular macln'ne of the type disclosed in the mentioned Lawson patent, continued roi5 tation of the needles causes the needles knitting the wales ii-iii inclusive successively to move past the knitting cams, whereby the stitches constituting the course 5 are drawn through the stitches constitut'mg the last plain course i. 5% Continued rotation of the needle cylinder carries the needles that knit wales i2-i8 around again to the wrapping mechanism. where the needles that knit wales i6, i5 and it are wrapped with thread 8. The needles that knit Wales 52, I3, 55 ii and 58, preferably, do not cast their stitches drawing cam, engage the body yarn l and draw the said yarn l and thread 3 through the loops constituting the course 5.

During the knitting of course i the needles knitting wales i2, i3, it, and 08 are again wrapped by thread 2, continued rotation of the needle cylinder causing such needles to engage yarn i, the stitch drawing cam then engaging such needles and causing them to draw loops or stitches of yarn i and thread 2 through the stitches of yarn I] and thread 2 which stitches were drawn through the stitches of course 4 during the knitting of course 5; at the same time drawing the yarn l and thread 2 through twowale loops formed respectively at wales- I2, l3 and ii, it by the yarn i which floats as shown at 253. During the knitting of said course i the needles knitting wales it, it, and it may engage the yarn i but are not actuated to cast the stitches of yarn t and thread 3 on their latches, the needles knitting the wales it, i5, and it accumulating loops or tucking.

Gourse i3 is then knitted and during the knitting of such course, the needles are all controlled and actuated as they were during the knitting of course 6, the only difference being that, whereas during the knitting of course 6 the stitches knitted by the needles knitting wales i l,

i5, and it were drawn through plain loops of course 5; in course 8 the stitches of yarn l and thread 3 are drawn through the stitches of yarn i and thread 3 which stitches were'drawn during the knitting of course it, the stitches of course 8 in wales til, it, it being also drawn through a three-Wale loop or stitch of yarn i which floats across such wales as at it.

While knitting the next course, i. e., course 9. the needles are actuated and controlled in the same manner as they were during the knitting of course 1, course 9 in the fabric being the same as course i; and following course in is likewise a duplicate of course 8, being knitted in the same manner.

As shown in Fig. 1, the loops knitted at the wrap wales are elongated, due to tucking, and are substantially two courses in length; also Wales i2, 93, ll, and is being wrapped during the knitting of one course, and the adjacent wales H,

another, results in a staggered or ofiset positioning of the wrap wales in the fabric.

The floats 22 of the wrap thread 2 between 5 courses l2, l3 and courses l1, l8 are closely adjacent to the inner face of the fabric and between the yales thereof and diagonally disposed floats 23 of thread 3, other and more or less diagonally disposed floats 24 of thread 2, which floats conl0 nect adjacent courses, are also disposed adjacent to the inner face of the fabric and between the wales thereof and the floats 23.

In Fig. 2 there is shown a modified form of fabric wherein three wrap threads are knitted into the fabric, and wherein the wrap stitches are elongated to span three courses.

The body of the fabric is shown as being composed of a body yarn 25 which is knitted throughout the, plain portion of the fabric, 1. e., other than the wrap area or areas, and is knitted together with one or more of the wrap threads in the wrap area or areas. Wrap threads 26, 21, and 28 are shown as being knitted into adjacent wales of the fabric; thread being shown as 25 being knitted into the fabric throughout wale 29 and at wale 30 together with wrap thread 26; at wales 3i, 32 with wrap thread 21; at wales 33, 34, 35 with wrap thread 28; at wales 36, 31 again with wrap thread 21; at wale 38 again with wrap 30 thread 26; and throughout wale 39, at which wale none of the wrap threads are knitted into the fabric.

In Fig. 2 a course is shown as being the last plain knitted course, i. e., prior to the incor- 35 poration of the wrap thread, during the knitting of which course 46 all of the needles knit all of the wales in the usual manner.

During the knitting of the first wrap course, i. e., course 4|, the wales 29 and 39 are knitted in 40 the usual manner, whereas wales 36 and 38 are knitted by their needles drawing stitches of yarn 25 and thread 26 through the stitches in wales 30 and 38 which were drawn during the knitting of course 40; the thread 26 being wrapped around the needles knitting wales 3D and 38 prior to the needles reaching the stitch drawing cam at or adjacent to which cam the said needles engage yam 25, the stitch drawing cam then causing such needles to draw yarn 25 and thread 26 through the previous course loops. During the knitting of course 4| the stitches constituting wales 3l-31 inclusive are drawn in the usual manner, i. e., as in plain knitting.

During the knitting of the following course,

i. e., course 42, the needles knitting wales 36 and 38 remain in an inactive, tucking position and consequently do not cast the previously drawn stitches off their latches, but may engage the body yarn 25 in their hooks. During the knitting of said course 42 the needles knitting wales 3|, 32, 36, and 31, are wrapped with'thread 21 prior to being engaged by the stitch drawing cam, said needles also engaging the body yarn 25 in their hooks; and as said needles are engaged 5 by the stitch drawing cam, loops of yarn 25 and thread 21 are drawn through the plain stitches of course 4|. During the knitting of said course 42, the needles knitting wales 33, 34, 35 continue to knit in the usual manner, 1. e., as in plain 70 plating. 7

During the knitting of the next course, i. e., course 43, the needles knitting wales 39 and 38 and which needles drew loops of the yarn 25 and thread 26 through loops or sitches of the course 40 and remained inactive during the knitting of l5 and 16 being wrapped during. the knitting of course 42, likewise remain inactive during the knitting of course 43 excepting that they again engage the yarn 25 in their hooks. The needles knitting wales 3|, 32, 36, and 31 also remain inactive during the knittingof course 43 in that their-loops are not cast off their latches although such needles engage the yarn 25 in their hooks. However, during the knitting of said course 43, the needles knitting wales 33, 34, and 35 are wrapped for the first time by thread 28 and, at or adjacent to the stitch drawing cam, the said needles engage yarn 25 and when engaged by the stitch drawing cam, form loops or stitches of the yarn 25 and thread 28 and draw the same through the plain loops of course 42. 1

During the knitting of the next course, i. e., course 44, the needles knitting the wales 39 and 38 are again wrapped by thethread 26 and, when engaged by the stitch drawing cam, draw such wrap thread and yarn 25which such needles engage in their hooks at or adjacent to the stitch drawing camthrough the elongated loops drawn through the loops of course 40 during the knitting of course 4|. During the same course of knitting, the needles knitting wales 3|, 32, 36, and 31 remain inactive in that they do not cast their loops off their latches, but they may engage yarn 25 then having three strands of three courses of such yarn in their hooks, the strand which was engaged in the hooks of the needles during theknitting of course 43 being elongated as compared with such strand at the wales 30 and 38. Needles knitting wales 33, 34, and 35 remain inactive during the knitting of course 44, but engage the yarn 25 in their hooks.

During the knitting of the next course, i. e., course 45, the needles knitting the wales 30 and 38 remain inactive without casting the loops of! the latches, but may engage a strand of yarn 25. The needles knitting wales 3|, 32, 3'6, and 31, however, are again wrapped by the thread 21 and again engage yarn 25,- the stitch drawing cam then causing the needles to draw stitches through the elongated loops originally drawn through the stitches of course 4 l. During the knitting of said course 45 the needles knitting wales 33, 34, and 35 are inactive to the extent that they do not draw stitches, but they may, however, engage a strand of yarn 25 in their hooks, such strand subsequently appearing as a float in the completed fabric.

During the next following course of knitting, i. e., course 46, although a strand of yarn 25 is engaged by needles knitting wales 36 and 38. such needles do not cast the old loops off their latches, having three strands of yarn 25 in their hooks.

During the knitting of said course 46 the needles knitting wales 31, 32, 36, and 31 remain inactive,

not casting the loops oflf their latches although they engage yarn 25 in their hooks. However,

during the knitting oi said course 46 the needles knitting wales 33, 34, and 35 are again wrapped by thread 28 and again engage a strand of yarn 25, subsequent engagement of the needles by the stitch drawing cam causing such needles to draw loops of yarn 25 and thread 28 through the loops originally drawn through the plain loops of course 42 and through the three-wale loops of the strands of yarn 25 engaged by the hooks of the said needles during the knitting of courses 44, 45, such three-wale loops floating'across the wales as at".

The immediately following course of the fabric is identical in formation and structure to the aoraaia course til, each succeeding three courses duplicating courses Mi, 45', and t6.

In the fabric shown in Fig. 2, the wales 3t and 38 are wrapped by the thread 26 and the inter- 5 vening wales, namely, iii-3i inclusive, not being wrapped by said thread, said thread floats across said wales, as at as; likewise the thread 21 is knitted at wales 3!, 32 and 36, 3f, floating across wales 33, 35, and 35 as at 49.

The fabric shown in Fig. 2 includes wrap and other loops which are elongated to span three courses, the loops of the respective threads 26, 2?, and 28 being drawn during the knitting of successive courses, the wrap stripes thus appearing more or less staggered or offset in the knitted fabric.

Floats 48 of thread 26, which floats connect wales 30, 38 and are formed during the knitting of single courses, are adjacent to the inner face of the fabric, being between the inner face thereof and more or less diagonally disposed floats 50 of thread 21 which diagonal floats 5!! connect adjacent courses. Between the floats 50 and the inner face of the fabric are also the diagonal 25 floats 5| of thread 26 which diagonal floats connect adjacent courses. The diagonal floats 52 of thread 28, which floats connect adjacent courses, are on the inner face of the fabric, the other floats, namely, 48, 49, 50, and 51 being he- 30 tween the said floats 52 and the knitted wales of the fabric. J

Although as hereinbefore disclosed, the portions of the fabrics other than the wrap areas, are knitted with one yarn i or 25, two or more yarns may be knitted into such portions of the fabrics in plating relation or otherwise; and other designs may be knitted into the fabrics in any well known manner if desired.

By knitting a fabric with a. plurality of wrap threads in a manner hereinbefore described, it is possible to wrap adjacent or other needles having threads of different colors or other characteristics, whereby the completed fabric shows a color or colors within another color or colors;

and, futhermore, the number of wrap theads which may be knitted into the fabric is not limited to three.

By knitting a wrap thread into the tuck stitches of the fabric, such thread reinforces the tuck stitches thus avoiding the usual weakness inherent in tuck stitch fabric.

Although as shown in Figs. 1 and 2, the wrap stripe area is knitted with wrap threads which wrap the same number of needles or wales from course to course, nevertheless clocking or other efiects may be knitted into the fabric wherein the number of needles or wales wrapped with a thread vary from course to course, the needles being selectively raised in any convenient manner to ensage such wrap threads in their hooks.

Wherever in the appended claims reference is made to alternate courses, there is no intention of thus limiting the claims to the first, third, fifth, etc. courses of the fabric; but by such lan- (i5 guage it is the intention to cover as well the first, fourth, seventh, etc. courses, or any other methods of fabrics wherein one or more intermediate courses are provided.

Although in the foregoing description specific terms have been used in describing the parts, nevertheless it is not the intention to limit the invention otherwise than as required by the claims.
