G. H'. WOOLLEY KNITTED FABRIC Feb. 12, 1952 original Filed Dec. 24, 194e Patented Feb. l2, 1952 George Henry Woolley, Woodside, England Original application December 24, 1946, Serial No.V 718,156, now Patent No. 2,529,207, dated November 7, 1950. Divided and this application February 18, 1948, Serial No. 9,151. In

Great Britain June 1, 1945 4 Claims. (C1. (i6-201) l This invention is for improvements in knitted fabrics and has particular reference to intarsia or argyll patterns. Intarsia fabric or split work is weft knitted fabric composed of a plurality of different weft yarns which are substituted one for another at predetermined intermediate points in each or certain of. the coursesv so that a given course consists of a predetermined number of stitches of one yarn followed by a predescribed with reference to the accompanying drawing which illustrates a portion of fabric (looking on the rear face thereof) and the carrier movements for producing it.

' In thedrawings there is shown the narrowed upper part of one diamond flanked by the widened lower parts of two adjacent diamonds; the yarn, of which the first mentioned diamond is composed'is shaded in order to render the diamond visually distinctive. The said diamond is termined number of stitches of another yarn l produced by a representative carrier on a rod without the withdrawn yarn floating behind the which, throughout thev courses shown, has its yarn substituted for it. An object of the inventraverse progressively reduced and may therefore tion is to improve the appearance of such patbe termed the narrowing rod. The two flankterns. ing diamonds are produced by two of the carriers It is already knownto provide fabric incorporl5 on the other rod, which, in the courses shown ating a series of diamonds and to knit an emhas' its traverse progressively increased, and may broidery thread over the diamonds to produce be termed the widening rod. At the end of each well known argyll patterns. Heretofore' howtraverse or draw of the rods, the widening rod is lever the fabric at vthe junction of each diamond shogged through one needle space (to widen the with the next succeeding diamond has been diamonds produced by its carriers) and the narsomewhat thick or bulky because at such juncrowing rod is shogged through two needle spaces tion at least one loop and usually two in each in the opposite direction (to narrow the diacourse has beencomposed of two threads (one mond produced by its carrier) .while the carfrom each of two adjacent patterns). riers are at the plain side. Thus, for example An important object of the present invention considering carriers 4a as being widening caris to reduce this bulkiness and the invention riers and carriers 4b as being a representative therefore provides intarsia fabric having at each narrowing Carrier it Will be Seen that in Course of selected points whereat the yarns are sub- A, at the end of the traverse to the right-the stituted one for another, a single composite loop carriers are swung t0 the plain Side of the needles of the stitch loops of the different yarns which 3.5, and while the widening carriers 4a are ShOgged are located at said point.

In one needle spaces to the right (in a narrowing direcexample the fabric may be produced by the mation) while at the back of the needles, while the chine described in the specication ofapplicawidening carriers 4a are shogged one needle tion Serial No. 718,156, led December 24, 1946, space to the left (in a widening direction). This now Patent Number 2,529,207 of which this apresults in there being one duplex loop 30' in course B, at the left hand juncture, which'is knitted of two yarns. If the carrier traverse is adjusted at every course a duplex loop (30 or 30') appears in each juncture only at every second course and at every second Wale, and it will readily be appreciated that by virtue of the spacing of the duplex loops the joint is much less bulky than if a duplex loop appears in every Wale and every course of the juncture.

As previously stated the fabric may be produced by any suitable means but preferably it is produced on the machine described in the U. S. patent application Serial No. 718,156, filed December 24, 1946, now Patent Number 2,529,207 of which this application is a division.

I claim:

1. A at knit fabric comprising three coursewise adjacent areas each knit of a separate yarn, said areas being joined by sutures which extend at an angle to the wales and courses, the yarn of the intermediate area being knit together with the yarn of one adjoining area in single stitches in alternate courses only and being knit together with the yarn of the other adjoining area in single stitches in intervening courses only, the yarn of said intermediate area being oated across at least one stitch coursewise adjacent one of said single stitches and being drawn through the next coursewise adjacent stitch to form the end stitch in an adjacent course of said intermediate area.

2. A at knit fabric comprising three coursewise adjacent areas each knit of a separate yarn, said areas being joined by sutures which extend at an angle to the wales and courses, the yarn of the intermediate area being knit together with the yarn of one adjoining area in single stitches in alternate courses only and being knit together with the yarn of the other adjoining area in single stitches in intervening courses only, the yarn of said intermediate area extending, without being formed into a knitted loop, across at least one stitch coursewise adjacent one of said single stitches and being drawn through the next coursewise adjacent stitch to form the end stitch in an adjacent course of said intermediate area.

3. A flat knitted fabric comprising two coursewise adjacent areas, each knit of a separate yarn, said areas being joined by a suture which extends at an angle to the Wales and courses, the yarns of said areas being knit together in single stitches in alternate courses only and the yarn of one of said areas being floated across at least one stitch coursewise adjacent one of said single stitches and being drawn through the next coursewise adjacent stitch to form the end stitch in an adjacent course of that area to which said floated yarn belongs.

4. A flat knitted fabric comprising two coursewise adjacent areas, each knit of a separate yarn, said` areas being joined by a suture which extends-at an angle to the wales and courses, the yarnsof said 'areas being knit together in single stitches in alternate courses only and the yarn of'one of said areas extending, without being formed into a knitted loop, across at least one stitch coursewise adjacent one of said single stitches and being drawn through the next coursewise adjacent stitch to form the end stitch in an adjacent courseA of that area to which said floated yarn belongs.
