KNITTED FABRIC.

Application filed March 26, 1921. Serial No. 455,894. 2

To all whom it may concern Be itknown that VINCENT LOMBARDI, a citizen of the United States, residin at Brooklyn, in the county ofKings and. tate of New York, has invented new and useful Improvements in Knitted Fabrics, of which the following is a specification.

The invention relates to the manufacture of knitted fabrics with the object in view of providing an improved knitted fabric consisting of a plurality of independent, in

one part transversely extending yarns,

forming interlocking loops in another part and particularly adapted for producing .a fabric of peculiar uniformity on both sides thereof, capable of various designs, particu-' point 1 and, thereafter, itself forms acourse of loops or stitches, whereas an adj acent yarn 2, forms loops or stitches .to. be

traversed by the substantially straight portion of yarn 1, before it, at 2', itself begins to form a substantially straight portion traversing the loops formed by yarn 1. Yarns 3 and 4 and any number. of succeeding yarns may be similarlyarranged and it is obvious that a variety of designs may be produced by proper selection of the num-, ber, dimensions and color of the different yarns.

The interlocking of the independent yarns is clearly shown in Fig. 2, and it will be seen that at the left of the. figure, the yarn 1 is located entirely behind the strands 4, 2, 2 and 4, forming the first vertical row of loops of Fi 1, the closed portions of the loops exten ing upwardly. The next adjacent vertical row of loops, having the closed portions of the loops extending upwardly, is traversed by yarn 1,'in passing between yarns 4 and 2, so as to be located behind yarn 4, 4, but in front of yarn 2,2.

The next adjacent verticalrow of loops corresponding to the first row and alternating with the adjacent rows, may appear repeatedly and in variations, and there is practically no limit to the modifications of arrangement of the yarns resulting in different designs. The change from traversing straight yarn into looping or stitching yarn is clearly shown at points 1 and 2', and it is obvious that by a proper disposition of this point of change, an additional element is provided useful in the production of designs of any desired character.

The greatly enlarged representation of a number of adjacent rows of loops or stitches, shown in Fig. 3, discloses at5, 6 and 7, three rows of stitches with upwardly extending closed portions of the loops, interlocked by alternating rows of stitches with downwardly extending closed portions of the loops. The traversing, substantially straight portions are shown at 8 and 9, and the bights engaging adjacent rows 'of' stitches,

at 10, 1 1, '12 and 13. Rear bight 10, of Fig.

3, shows the engagement by yarn 1,0f the first group of strands'4, 2, 2, 4, at the extreme left of Fig. 2, while front bight 13, shows the engagement of yarn 1 and the second group of strands 4, 2, 2, 4, in which the two outer strands 4, 4, are in front, and the two inner strands 2, 2, behind the traversing yarn 1. Theabsence of floats peculiar to the arrangement of yarns according to the present'invention, is of importance resulting in. an increased uniformity and durability of the fabric.

The above described arrangement wherein the unlooped portion is interlocked in alternate rows has special advantages since the unlooped portion is interlocked between the loops of the other yarn in a maximum number of positions. It has been found necessary to pass the unlooped yarn behind alternate wales in order to insure locking in the remaining wales. Thus, if the unlooped yarn in every wale were knitted between the loops of the other yarn, the unlooped yarn would be substantially straight between its knitted portions and, as a consequence, no interlocking would result, since the interlocking depends upon the zigzag path given the unlooped yarn. It has, theredone in alternate or every other Wale rather than in any other manner. 'On the other hand, if. an attempt is made to interlock the unlooped yarn every fourth or every fifth Wale, for example, passing the looped yarn behind the remaining wales, objectionable floats are formed as previously described. Even in the case where the unlooped yarn is interlocked every fourth Wale, the unlooped yarn being carried back of only two successive wales, the part carried back hangs away from the fabric an amount far more than would be expected from the appearance of a fabric wherein the yarn is carried back of only one Wale at a time as shown in the drawings illustrating this invention. The dangling yarn is, of course,

highly objectionable since it is likely to be broken by being caught or snagged. Since dangling portions are formed by carrying the unlooped yarn behind even only two wales at a time and since these dangling portions are entirely absent when the unlooped yarn is carried behind only one Wale at a time, it is, therefore, essential that the unlooped yarn be interlocked in alternate Wales rather than every fourth Wale or in any other manner.

What is claimed is A knitted fabric comprising a plurality of independent yarns making certain portions of the front of said fabric one color and other portions another color, each of said yarns in turn forming a looped portion and a transversely extending unlooped portion, the looped portion in each instance determinin the color of the front of the fabric, eac of said yarns in its unlooped portion being interlocked in alternate wales between the two sides of a loop in one row I and the two sides of a loop in an adjacent row of yarn of the other color, each unlooped portion in the remainingwales being carried entirely behind the looped yarn
