If two yarns or threads only are fed to the needles, the lap stripe shows or other figures or designs, extending generally lengthwise of the stockingand characterized by ' clearly; but if it is desired to combine 'the lap the knitting-in of -a supplemental yarn or yarns stripe with reverse plating then it'becomes dimf. in addition to- the main or body yarn and more -cult to knit vthe main, the plain plating and the .specifically to the knitting ~of stripes or ñgures by means of a wrapping of yarn or thread fed to certain selected needles in each course of knit ting, in the manner disclosed in the patent to Lawson and Lawson‘1,702,608, February 19, 1929, of winch the present application is a continua -tion as to all common subject matter. This ap plication is also a continuation, as to all common subject matter, of application Ser. No. 333,318, filed January 18, 1929. For purposes of illustration, Flgs.'2-6 of the drawings, which show the inner or rear faces of the several fabrics, show body yarns as well as plating yarns in the plain plated wales, and all three yarns-including the Wrap stripe 4yarn---in some of the wrap stripe wales; although actually ' the body yarns alone show, or show more promi -nently, at the inner faces of the fabrics.. Of course, where reverse plating occurs the body wrapping yarns, when knitting wide stripes, with out the plain plating yarn breaking the continuity of the lap stripe. ' - The various forms of the fabrics disclosed in the drawings and speciñcation all have two yarns, namely, a main or body yarn and a plain plating yarn, both yarns being knit-in throughout the wales not within the lap stripe areas, designs being knitted by reversing the body and lplain plating yarns, as indicated at D, Fig.` 1, in' the wales not supplied with the .lap'stripe plating yarn; or the body yarn may be knit-in throughout andthe plating yarn substantially throughout but ñoated back of the body yarn wheredesigns or other figured effects are desired as at E, Flg.‘1, the body yarn showing upon the face of the fabric at the 25 ’ wales where the plain plating yarn ñoats. During the knitting of the lap stripe, the plain plating yarn is floatedl back of all the lap stripe yarn shows at the face wales, and the plain plat- . wales or some of .them only, . whereby, at. said wales, not more than two yarns will be knit-in, ing yarn on the inner or rear face of the fabric. the plain plating andin some cases also the main 30 In» the accompanying'drawings: » ~ ‘ yarn or thread floating back of such wales -to Fig. 1 shows a side view of a half hose or stock ing having stripes knitted therein, which stripes vgether with the rear stretches of the lap stripe .

In this form the plain In the form of fabric shown in Fig. 6, plain plated Wales 4I, 42 are followed by intermediate, lap stripe wales 43, 44, 45, such lap stripe wales being, in turn, followed by plain plated Wales 46, plating yarn 8 floats across all of the wales of the 41. The plain plated wales are knitted With the lap stripe areas, which though shown in Fig. 2 plain plating yarn 48 and the body yarn 49; where and Figs. 3, 4, 5 and 6 as consisting of the same as the lap stripe wales are knitted with the lap stripe yarn 5I) only, the plain plating and body number of Wales, from course to course, may, as ` disclosed in Fig. l at C, Vary from course to course. 10 The body yarn 9, Fig. 2, on the other hand, is knit in throughout the lap stripe areas as Well as in yarns 48, 49, floating across the intermediate Wales. The interlocking of the lap stripe floats 10 with the floats of the plain plating and body the plain plated portion of the stocking or fabric. _yarns is availed of to connect the intermediate The lap stripe plating yarn I0 is fed to the selected wales with the plain plated wales. . 1t win be understood than in au the forms ' needles by wrapping the said yarn therearound, disclosed, the main or body yarn, the plain plat 15 15 the rear or non-knitted portions of the wrapping yarn appearing as floats back of the knitted , ing yarn, and the lap stripe, plating yarn may wales. Each lap stripe float passes to the rear havedifferent characteristics as to Weight, color of the plain plating yarn float, then around again forward of the said float Where it is caught by the 20 ñrst needle in the following course and knit-in t0 gether with the main yarn, the lap stripe and plain plating yarn floats thus interlocking. The striped fabric shown in said Fig. 2 is uniform throughout to the extent that there are two knit-in yarns in _ 25 all of the wales._l In the form shown in Fig. 3, the first Wale, which is plain plated, is indicated by the numeral II: the first lap stripe Wale is indicated by I2, and has three knit-in yarns; I3, I 4, I5 are the intermediate 30 lap stripe wales whereat two yarns only are knit in, the plain plating yarn floating; I6 designates the last lap stripe Wale and has three knit-in yarns; ‘ I1 designates the next following plain plated Wale beyond the lap stripe area. 'I‘he plain plating yarn I8 is thereby effectively hidden by floating back of the intermediate wales of the lap stripe, being knitted together with the main yarn I 9 and lap stripe yarn 20 at the ilrst and last lap stripe wales only of a given course. In the form shown in Fig. 4, 2| is the last plain plated Wale; 22 is the first lap stripe Wale, at which Wale all three yarns are shown as being knitted; 23, 24, 25 are the intermediate wales hav ing one knitted yarn only,” namely, the lap stripe 45 yarn, there being three floats including the rear stretch of the lap stripe yarn; 26 is the last lap stripe Wale, all three yarns being knitted-in in said Wale; 2'|_ is the following plain plated Wale and is and quality, cotton, silk and artificial silk ordinar ily being used. ' The fabric shown in Fig. '7 corresponds to that shown in Fig. 2 excepting that the designs knitted into the fabric are stepped, in other Words, the Wrap stripe thread 5I is knitted into the fabric at one or tWo- wales (two such wales 52 and 53 being shown) and thereafter is knitted into adjacent 25 Wales 54 and 55 only, floating across wales 52 and 53,-'following which the said wrap stripe thread 5I is knitted into wales 56 and 51 only, floating across wales 52-55 inclusive. The fabric design disclosed in Fig. '7 has, for 30 illustrative purposes only, been shown and de scribed as corresponding to the form of fabric dis closed in Fig.I 2; however, the broken or stepped designs may obviously be knitted into the fabric and either or both body yarns may be floated 35 across somewales and knitted into others as dis closed in Figs. 3-6. - Although a striping yarn has been referred to throughout this specification, it is not the inten tion to restrict this invention to the use of a single 40 striping yarn as, ordinarily, and as disclosed in the Lawson and Lawson Patent 1,702,608, several such striping or lap stripe, plating yarns are used, certain needles‘lmitting one of the said striping yarns and other needles-knitting another such 45 yarn. - In all the forms disclosed, the plain plating and lap stripe plating yarns are knitted, preferably composed of two yarns only. The fabric disclosed ' though not necessarily, under tension, 'as light a tension as possible being maintained on the lap 50 50 in Fig. 4 differs fro-m that shown in Fig. 3 in that the intermediate Wales 23, 24, 25 are composed of a single knitted yarn, the plain plating yarn 28 as well as the main or body yarn 29 floating back of and across the intermediate wales 23, 24, 25 of the 55 lap stripe, the lap stripe yarn 30 only, being knitted-in at the said wales. Fig. 5 discloses still another form more like the form shown in Fig. 2 than those of Figs. 3 and 4 in some respects; both Figs. 2 and 5 showing fab 60 rics wherein there are not more than two yarns knitted at any Wale. In the form disclosed in Fig. stripe or reinforcing yarn; the body yarn, on the other hand, being free from tension or ~substan tially so. In the several modifications disclosed herein, float threads are the result of the knitting of 55 the striped fabric, the lap stripe itself leaving floats and, the main or body yarn and the plain plating yarn appearing as floats in certain of the modifications; the ñoats may, however, be cut, if desired, the cutting aiding the elasticity. 60 The cutting would, preferably, be by an operation 5 the last plain plated Wale 3| is followed by the first lap stripe Wale 32 adjacentv to which are the intermediate wales 33, 34, 35 or the lap stripe- area, 65 said intermediate Wales being identical with the intermediate wales 23, 24, 25 of Fig. 4, in that the subsequent to the knitting Aof the stocking or other fabric and is therefore not herein disclosed, not forming a necessary part of the invention.
