25 claims.

rlfhis invention relates to knitted fabric. A An object of the invention is to provide knitted fabric having unusual design elfects.

Another object is the provision of Various im- 5 proved types of fabric.

Other objects of the invention will in. part be obvious and will in part appear hereinafter.

The ordinary types of knitted design fabric depends for its pattern entirely on the use of yarn of various colors or characters. Such design fabrics, while highly desirable for many purposes and embodying in some instances a wide variety of design,- do not, in essence, differ Widely in design effect from the design effects of woven design fabrics or printed fabrics. Knitted fabrics are not, however; subject to such inherent limitations of design as are woven design fabrics and printed fabrics, and the present invention is accordingly directed to certain types of knitted design fabrics mi wherein unusual design effects may be obtained regardless of whether or not the yarns employed are of dierent color or character, and, also, to

' knitted fabrics wherein various knitted portions of yarn are interconnected in particularly effec- M tive and/or attractive manners.

In accordance with the invention warp yarns are employed in the fashioning of such fabrics whereby wide variability in design eects may be secured. Such yarns may be employed in only those portions of the fabric wherein design effects are desired or may be present thruout the entire fabric if desired; the invention in certain of its aspects contemplating the provision of fabric composed entirely of Warp yarns, each of at least a plurality of such yarns extending backland-forth coursewise of the fabric in at least a portion of its extent. Fabrics of the latter character may be of relatively light weight and may be economically produced, and at the same time may embody widely varying design Vformations whether the design .depends upon a difference of color or character of the yarns or on differences in knitting in certain portions or on both.

.among the features of the present invention are the provision of design portions resulting from knitting of yarns in a special manner as by knitting of certain yarns in additional courses than other of the yarns to provide Vbulge or other effects; the knitting of individual yarns of such manner that ends of successions of loops are drawn toward each other to provide rope-like or other edects; and the provision of fabrics wherein some or all of the portions of the fabric are composed only of warp yarns some or all of which bil bili

extend back-and-forth over a substantial number of wales.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the articles hereinafter described and the scope of the application of which will be indicated in the claims.

Fior a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

lin the form of construction shown in Figs. l and 2, there is illustrated a portion of a fabric embodying the usual coursewise-extending weft yarn t of which much of the body of the fabric is composed in the present instance; and warp yarns which provide design eects in the present instance, and three of which are shown at 5, t, and l. These yarns may all be of the same color and character, or may be of different colors or characters as may be desired in a particular case. For example, the body yarn t may be white yarn, the yarn 5 red yarn, the yarn d blue yarn, and the yarn 'l green yarn. The portion of the vfabric shown comprises wales o thru o, and the weft yarn 4 provides courses 8 thru 20. In the present instance the body yarn is knitted in wales a, b, h, i, lc, Z, n, and o; the warp yarn 5 extending back-and-forth thru wales c-g, and being knitted in one course as it extends in one direction and in a succeeding course as it extends in the other direction, the weft yarn 4 extending in an undulating manner thru these wales without knitting, being caught therein under the sinker loops of the yarn 5, in the present instance, in` such manner that it lies against the rear of the fabric. This may be performed by causing the yarn to extend behind one or more needles and then in front of one or more needles, as for example by partially raising certain spaced latch needles or spaced groups of latch needles in a latch-needle machine, as exemplified for instance in various of my patents, including Patents Nos. 1,541,230 and 1,728,293. The yarn 4 also extends under those portions of the yarn 5 which extend vertically across a Wale, as exemplified at 2I and 22. By thus extending under portions of the yarn 5, the weft yarn holds wales c thru g in the fabric. The yarn 6 is knitted in Wale j and extends vertically behind the weft yarn as exemplified at 23 and 24, so as to be held into the fabric, the weft yarn floating across Wale y' as indicated. The yarn 1 is knitted in Wale m and is held in the fabric in the same manner as the yarn 6.

At certain points in the portion of the fabric exemplified, the yarn 5 and 1 are knitted in supplemental courses to provide thickened eiects in the nature of bulges. The yarn thus knitted is connected with the fabric at the walewise ends of the bulges, but not at the coursewise ends thereof. One such bulge which is provided by the warp yarn 5 is exemplified at A. In the formation of this bulge, the loops of the weft yarn 4 in course I2 may be held on the needles while successive supplementary courses of the yarn 5 is knitted to provide a series of coursewise successions of loops. In the present instance eight such successions of the yarn 5 are knitted while the needles knitting the yarn 4 are inactive, so that abroad bulge, the outline of which will be seen clearly from Fig. 2, is provided. As will be seen, the bulge in substance includes these eight rows of the yarn 5, as Well as a ninth row cast at the same or nearly the same time that the course I3 of the weft yarn 4 is cast; the rows of the bulge being indicated at I2a--I2i in Fig. 2. The bulge in the present instance is ve wales wide thruout its extent. Another such bulge which is provided by the warp yarn 5 is exemplied at B. In the formation of this bulge, the loops of the weft yarn 4 in course I6 may be held on the needles while successive supplementary rows I6a-I6e of the yarn 5 is knitted to provide a series of successions of coursewise extending loops, which, together with the row I6f, which is cast at the same or nearly the same vtime as the weft yarn 4 in course I1, provide the ve-wale bulge B, which is, as will be seen from Fig. 2, narrower`than the bulge A. As will be seen, rows I2b-I2h and I6b-I6e are entirely unconnected with the fabric coursewise thereof, being bound to the fabric by the end rows I 2a and I 2i in the case of bulge a, and I6a and |61 in the case of the bulge B. Likewise, the vyarn 1 is formed into bulges C and D which are similar to the bulges A and B, and are similarly formed, except that the bulges C and D are only one wale in width. These bulges, like the bulges A and B, provide walewise successions of loops which are unconnected with the body of the fabric except by the end loops. As will be seen, the yarn which does not form the bulgethis yarn being the weft yarn 4 in the present instance-serves to interconnect the portions of the fabric at the upper and lower ends of the bulges at points laterally of the bulges. The yarn 6 provides no bulges in portion of the fabric exemplified, and its showing indicates that a warp yarn may be present Without being knitted to provide a curled portion, such for example as bulge, in the fabric. It may, however, be formed into bulges or otherwise curled portions in other parts of the fabric is desired.

In Figs. 3 and 4, there is illustrated a portion of a fabric embodying a somewhat different type of bulge. This bulge, shown at E, is longer than the bulges A and B, and, in order to prevent the fabric from flattening the center wales of the bulge by drawing it apart in a walewise direction, the portions of the fabric above and below the bulge are, in accordance with the invention, interconnected intermediate of the sides of the bulge as well as at the sides of the bulge. The bulge, in this instance, is even narrower than the bulges B and D, but it will be appreciated that long broad bulges may be employed as well as short narrow bulges, short broad bulges, and long narrow bulges in accordance with the various aspects of the invention. The fabric of Figs. 3 and 4 is generally similar to the fabric shown in Figs. 1 and 2, the portion illustrated comprising weft yarn 36 which extends coursewise thruout the extent of the fabric in the present instance. The portion of the fabric shown comprises` wales a' thru m' and courses 28 thru 35. The yarn 36 is knitted thruout wales a', b', e', i', l', and m'. The loops in the remaining wales are formed by a warp yarn 31, which extends backand-forth across wales c'-Ic'. The weft yarn 36 extends across wales c and d', f-h', and 7" and k', without being knitted. In al1 of its courses except course 32 it is caught under portions of the knitted Warp yarn as it extends past these wales, being caught in the present instance under the sinker loops between Wales c and d', under the sinker loops between wales f' and g', and between wales g and h', and under the sinker loops between wales j and 1c', and thus tending to hold the fabric together. The Warp yarn as it extends back-and-forth floats past wales e and i' without being knitted, extending at the rear of the fabric at these points, and additionally serving to hold the fabric together by providing an interwoven effect in those courses which are below and above the bulge.

In the formation of the bulge exemplified at E, the loops 'of the weft yarn 36 in course 32 may be held on the needles while a single supplementary roW of the yarn 31 is knitted. In addition, in the knitting of course 32, the weft yarn is left entirely free of the needles in wales c', d', f', g', h', 7", and k', so that this yarn, instead of holding the fabric flat, will float freely from Wale b to Wale e', from Wale e' to i', and from wale i' to Wale l without connection with the yarn 31. Thus in each Wale of the yarn 31 there are three loops which are not held flat in the fabric, and which provide a bulge consisting of rows 3Ia, 32a, and 32h. In these rows, since they are free from the holding effect ot the weft yarn 36, the loops tend to draw together, particularly in the center row 32a, so that the loop in the Wale d tends to draw close to the loop in wale -f and the loop in Wale h' tends to draw close to the loop in wale i', thus 75 asesinos providing a six-Wale bulge which extends over eight-wales, although it tends to draw inwardly somewhat in a coursewise direction.

As above indicated, the invention in certain of n its aspects contemplates the provision of fabric composed entirely of warp yarn. In Fig. there is exemplified a portion of a fabric wherein a number of warp yarns extends back-and-forth to provide a number of zones in the fabric, these Zones being held together by, a zigzag over-lap at their edges. In the present instance certain oi these warp yarns are knitted to provide bulges, and in addition there is another warp yarn which appears in a single wale of one of the'zones and which is knitted to provide bulges. the portion shown are indicated at I, II, III, and IV, which are formed respectively of yarns d6, ill, 6I, and 43; parts of a yarn 45 being shown at the left or Fig. 5, and parts of a yarn 66 being shown at the right of Fig. 5. A yarn 6I is knitted in` one wale of the zone IV. In the lowermost course of Fig. 5, the yarn lll is knitted in the rst live wales, the yarn di in the next rive wales, the yarn 6I in the next rive wales, the yarn dit in the next I6 wales, and the yarn. 66 in the last two wales. In the next course from the bottom, the yarn 66 is knitted in the rst Wale, the yarn 66 in the next five, the yarn ill in the next ve, the yarn 6I in the next iive, the yarn d6 in the next ten, and the yarn 66 in the last Wale. In the third course from the bottom the arrangement of the lowermost course is repeated, and the zig- Zag arrangement is thereafter continued, thus giving a one-Wale over-lap whereby, in the rlrst 6th, llth, 16th and 26th wales, yarns from alternate zones are interknitted so aslto securely bind the different zones together. The yarn 6I is incorporated in zone IV in the same manner that the yarns 6 and 'l are incorporated in Fig, I, the W yarn lil extending vertically behind the floats of the yarn d3, except where the yarn dl is formed into bulges.

Suitably spaced bulges are formed in zones II and III of the fabric, each of these bulges in the lll lili

m present instance comprising six rows, including the row corresponding to the omitted portion of the course in the ilat fabric. The alignment of the wales of the bulge with respect to the yarn in adjacent zones corresponding to what the 50 alignment of the loops would be lf the bulge did not occur. A portion of one of these bulges is shown at Fin zone II beneath the lowermost course shown. Another such bulge is shown at Gr in Zone III curling aboutthe space which would be occupied by the fourth course from the bottom if this were continuous. In zone II there is shown a bulge H at the eighth row from the bottom; and. in zone III a bulge at the twelfth row from the bottom oi' the figure. Each of these bulges is live wales wide.' 'Ihe yarn All is formed with bulges in coursewise alignment with each of the bulges F, G, H, and I, these bulges each having a number of loops corresponding with the nurnm ber of rows in the bulges in zones II and III.

In Figs. 6, 7, and 8 there is shown a form or construction wherein portions of warp yarns are knitted to form a walewise series oi coursewise successions of loops with the loops intermediate x The zones in nature oi ropes. The portion of the fabric exemplified in Fig. 6 is divided into ve zones. In each of zones I, III, and V, a weft yarn 50 which in the present instance extends coursewise thruout the extent of the fabric is knitted thruout four wales, In zone II, the weit yarn 5U is unknitted, but iive wales of a warp yarn 5I which extends back-and-forth thruout the portion of its extent shown are provided. In the 3rd, 4th, and 5th courses from the bottom and in the 2nd, 3rd, and 4th courses from the top, this yarn is knitted in one direction in each course, but is floated in the other direction, the weft yarn 50 being caught under the sinker loops of the knitted warp yarn 5l so as to lie predominantly at the rear of the fabric in the same manner as the yarn Il is caught under the loops of the yarn 5 in Fig, I. This arrangement is illustrated in the lowermost part of Fig. 7, wherein the yarn 6l is shown knitted in one direction as, at 52 and 63, and floated in the other direction, as at till and 65, and the weft yarn Ell is shown caught under the sinker loops of the knitted row 66 at 66 and 6I.

In the middle courses of zone II or Fig. 6, the yarn 6l is so knitted as to provide a rope-like eect J, the construction being more readily understood by references to Fig. 7 in which it will be seen that in the course above the lowermost part oi the gure the weft yarn 66, instead of being caught under the sinker loops so as to hold the warp yarn lil flat, is floated to provide a plurality ol extents 66 which extend under the floats f 56, 66, 6l, 62 and 66 of the warp yarn as it extends in the direction in which it is not knitted. As the warp yarn extends upwardly from the course 66, these floats tend to pull the end loops of the live-loop successions of knitted warp yarn together, the float 66 being shorter than the float 65, and the float 60 still shorter, etc., until the float 63 is substantially in the form of a sinker loop. Since the oats dll-66 extend at the rear of the floats 58 of the weit yarn, the end loops of the ve-wale successions of loops are connected with the weft yarn 66 but the three intermediate loops are unconnected with the weft yarn 56 and are free to curl around to provide a rope-like effect. In the top course. and the two lowermost courses of Fig. 6, the lower and upper parts, respectively, of additional rope-,like eiects are shown.

In zone IV of Fig. 6, there is provided a warp yarn 6d. Ihe arrangement'in the 3rd, 4th and 5th courses from the bottom and the 2nd, 3rd, and 4th courses from the top, is the same as in zone II, the yarn 64 being knitted in rive wales in one direction and floated in the other direction, and the weft yarn 56 extending in an undulating manner at the rear of the knitted warp yarn and being caught under the sinker loops of the warp yarn. In the middle of the zone,

Vthere is formed a curled portion K of rope-like conformation similar to the rope-like portion J in the middle of zone II, except that the weft yarn 56 is knitted along with the yarn 64 in the right hand `wale so as to provide a plated effect as illustrated at 65 in Fig. 6. In the upper course and the two lower courses of zone IV of Fig. 6 parts of similar rope-like effects are shown.

In. Fig. 9 there is shown a portion of a fabric wherein weft yarn 66 is unknitted, wherein warp yarns 6I, 68, and 66 are knitted in zones I, III, and Vto provide stripes which are five wales wide, and wherein warp yarns 'ld and 'il are knitted in zones II, and IV to provide five-Wale rope-like eiects L and lVI which never flare as does the yarn 5| at the bottom of Fig. 7, but which thruout their extent correspond to the uppermost part of Fig. '1, so that there is a continuous gap in the fabric between the ropes in zones II and IV and the stripes in zones I, III, and V. The arrangement of the yarn 61 in zone I is similar to the arrangement of the yarn 5 in the uppermost part of Fig. l, for example; the arrangement of the yarns 68 and 69 in zone III and V, respectively, being similar to the arrangement of the yarn 61 in zone I. The weft yarn 66 extends only thru portions of the walewise extent of the fabric. In the upper center of the fabric, there are shown four strands of the weft yarn 66 whichvextend at the rear of the fabric in zones I, III, and V in an undulating manner and are caught under the sinker loops of the yarn 61, 68, and 69, in the same manner that the yarn 4 is caught under the sinker loops of the yarn 5 in Fig. 1. These four strands are caught into the ropes formed by the yarns and 1| in the same manner as the strands 58 are caught into the ropes shown in Fig. '7. In the lower center of Fig. 9 there are shown five strands of weft yarn 66 and which similarly extend at the rear of the fabric caughtunder sinker loops of the yarn 61, 68 and 69 in zones I, III, and V, in the same manner that the yarn 4 is caught under the sinker loops of the yarn 5 in Fig. 1. However, instead of extending directly across zones II and IV, in the present instance, these five strands are gathered together where the upper two strands extend downwardly and the lower two strands extend upwardly, and the group of strands are caught in zones II and IV together. Except for the grouping, they are caught into ropes formed by the yarns 10 and 1| in the same manner that the strands 58 are caught into the fabric in Fig. '7. As will be apparent other strands of weft yarn caught in the different zones in one of the above manners, for example, may be present in the fabric above and below the portion of the fabric illustrated in Fig. 9. In this manner, the fabric is held together so that the various warp yarns in conjunction with the weft yarn provide a distinctive fabric having a highly attractive lace-like effect.

As above indicated various types of fabric embodying the invention may bepformed without the provision of weft yarn. In Fig. 10 there is indicated a portion of a fabric wherein rope-like effects are provided but wherein weft yarn is not present. 'I'he portion illustrated comprises three zones, II, III and IV, and portions of two other zones, I and V, and the fabric is composed of a plurality of warp yarns each of which, in the portion of the fabric illustrated, is formed into a walewise series of coursewise successions of loops.

effect shown in the center of zone 1I of Fig. (j,

and illustrated in further detail in Fig. '7, rexcept that no weft yarn is present. In the fourth course from the top of Fig. 10, and in the fth course from the bottom of Fig. 10 the yarns 12 and 14 are knitted only in three wales and yarn 1|', 13 and 15 are knitted in seven wales, so as to extend into the outer wales of zones II and IV to be interknitted walewise with the yarn 12 or 14, as the case may be, thus tieing the yarns in the different zones together and holding the fabric flat at these points. It is to be noted that in the top course and in the two bottom courses of Fig. 10, the ends of the rope-like effects similar to those shown in the center of the figure are shown. In the second course from the top and the third course from the bottom, the yarns 1|', 13 and 15 are knitted in seven wales and the yarns 12 and 14 are knitted in only one Wale so as to assist in tying together the different yarns of the fabric and the holding of the fabric flat at these points, and also to give desirable design effects when, for example, the odd-numbered yarns are one color, for instance blue, and the even numbered yarns are of another color, for instance white. In the present instance, each of the yarns composing the fabric is knitted only in one direction and is floated in the other dlrection, as in the case of the yarns 5| and 64 in zones II and IV of Fig. 6. It will be appreciated, however, that, if desired, a yarn, instead of being floated in Athe second, third, and fourth wales from the top and the third, fourth, and fth wales from the bottom as it extends in the said other direction, may be caught under suitable sinker loops of the knitted yarn, if desired, or may be otherwise caught without knitting, or even knitted in certain instances.

In Figs. 11 and 12 there is exemplified a form of fabric having a design portion wherein a bulge and a rope-like e'ect are combined. The p0rtion of the fabric illustrated in Fig. 11 embodies courses 16-83 and wales r-z. Weft yarn 84 is knitted in wales 1', .'c, y, and e, and a warp yarn 85 extends back-and-forth thruout wales s-w, being knitted as it extends in one direction and being floated as at 86 as it extends in the other direction. 'I'he weft yam 84 in all its courses is caught under sinker loops of the warp yarn 85 so as to extend in an undulating manner across wales s-w and to hold the fabric together. Between the courses 19 and 8| the warp yarn 84 is knitted to provide ten additional courses which, together with the courses corresponding to the course 80, provides an eleven-row five-course bulge. This bulge differs from the bulges of Figs. 1-5, however, in that the warp yarn 84 is only knitted in one direction, being floated in the other, so that the floats will tend to draw the edges of the bulge together to provide a ropelike effect in the bulge, the construction of this rope-like portion being similar to that of Fig. '1 with the exception that the weft yarn does not extend therethru as in Fig. '1. As Iin Fig. '1, the floats tend to become shorter and shorter until they are similar to the sinker loop near the center of the bulge, these floats being indicated at 86a-86k. There is thus provided a design effect which curls in both a coursewise and walewise direction.

Since certain changes may `be made in the above articles and different embodiments of the invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

A knitted fabric comprising weft yarn and warp yarns, each of at least a plurality of said warp yarns comprising a portion containing a walewise-extending series of' short coursewise rows of loops with the end rows of said portion caught by weft yarn and intermediate rows unconnected with the Weft yarn or with the other of said warp yarns.

20. A knitted fabric comprising weft yarn and Warp yarns, a plurality of said Warp yarns being knitted to provide a plurality of walewise-extending plural-Wale strips connected at at least one of their ends by weft yarn and unconnected intermediate their ends, the weft yarn being absent from a portion of the vfabric containing said strips.

21. A knitted fabric comprising a. portion including a pluralityof walewise and coursewise successions of loops, each of certain of said coursewise successions having its end loops drawn together in the knitting thereof so that the succession Will bend back upon itself, and each of other' of said coursewise successions being substantially flat.

22. A knitted fabric formed of a plurality of yarns and comprising a portion composed of Warp yarn knitted to form a plurality of 'wales and rows of loops, said portion being free of loops of other yarn, the end loops in at least each of certain of said rows being interconnected by an extent of said warp yarn which is shorter than its row.

23, A knitted fabric including a walewise succession of loops of yarn which succession is connected with the fabric only thru its end loops and in which the end loops are drawn together so that the succession will bend back upon itself, said yarn extending into adjacent portions of the fabric.

24. A knitted fabric comprising a warp yarn extending back and forth in a portion of the fabric of limited coursewise extent and incorporated in the fabric in such manner as to lie flat in certain coursewise extents thereof, said yarn being incorporated in certain other of its coursewise extents to form a series of coursewise and walewise successions of loops with the central loops of the coursewise successions projecting to form a bulge.

25. A knitted fabric comprising a warp yarn extending back and forth in a portion of the fabric of limited coursewise extent and incorporated in the fabric in such manner as to lie flat in certain coursewise extents thereof, said yarn being incorporated in certain other of its coursewise extents to form a series of coursewise and walewise successions of loops with the end loops of the walewise successions drawn together so that the walewise successions will bend back upon themselves.
