More spaci?qally, it has reference to plain-and ribbed ' fabrics knit ‘from courses have in each instance been distinguished, . one from another, by conventional surface ?ne count silk,'rayon, etc.; as shading._ well-as to methods of producing such‘ fabrics ' 5 commercially. ‘ The aim ofmy invention ' a _ l _ ‘ Referring to Fig. I, successive courses of the is to make ‘possible’ fabric A there shownv are designated by the nu " - merals IA. The needle wale loops of ‘the courses the production from a single thread of fine count, a plain knit sheer-fabric for stockings and the like which is of- closer texture than possible of '10 ‘attainment heretofore, and which moreover is "ringless” i. e. devoid of horizontal streaks. ' The foregoing advantages I realize in practice, as hereinafter more fully disclosed, through‘ a 1, 2, 3, and 4 areindicated» at ll, l2, l3 and Id .and the sinker wale loops of said courses at 2|, 22‘, 23 and 24. The- characterizing features of the‘ 10 fabric A in 'Fig. I are that the sinker wale vloops ‘ of ' each "course of the knitting are transposed to . adjacent courses; 'andthat said sinker wale loops form inverse loop wales between the, needle wale new method of knitting as a result of which the loops at one side of the'fabric... Thus the sinker 15 sinker wale loops connecting neighboring needle wale loops 2| of thecourse _l are interknitted wale loops of one course of the fabric are .con- , with the needle wale loops l2 of the course 2, the sis'tently transposed‘ to other courses more or less sinker "wale loops 22 of the course [with the ‘ ‘remote from" the courses in which said sinker , needle wale loops is of the course‘ 3, and so on wale loops originated," and forming distinct wales throughout the fabric, the needle and sinker wale 20 20 of interlooped sinker loops between the needle loops being however montinubus in the needle wales. As a consequence of such consistent transposal of the sinker, wale. loops, the in equalities inherent in the yarn used in the knit and sinker Iwales as in ordinary knitted fabrics. The fabric A of Fig.‘ I may be'produced on a . flat knitting machine of the “Cotton” type ‘provided, as shown in. Figs. IV-VII, with two-sets 25 ting are effectively distributed throughout the fabric ‘with avoidance of streaks ‘or rings. Fur ther advantages resulting from‘my new?method, are that the fabric produced is of a gauge twice . as fine as fabric'produced in the ordinary way on commercial knitting machines, and character-. 30 ized by having the loops in alternate wales in of needles 50 and 5|, a press edge 52 for closing the beards of the needles'i?,‘ and a ?xed supple- I mental presser bar 53 for the-needles 51, the usual sinkers and ‘knock-overs being shown] re ' spectively at 54 and '55. In Fig. IV, the needle‘ 50' 80 is about to descend to draw the loop II for .the verted in respect to the loops of the other wales. Other objects and attendant advantages will I appear from the detailed description which fole ‘ lows of the attached drawings, wherein Fig. I 35 is. a diagrammatic view showing the texture of ‘one form of my improved fabric. ; » Figs.

The needle 5| ' 'on the other hand is. ascending through the loop 12 vof the .85 course 2_ and the loop l3 of the course 3 previous’ , - ly cast from the needle 50. The relative posi ' _' , tions of the loops _l I, I2 and I3 at this stage of the knitting cycleis shown in plan in Fig. VIII. Figs. IV, V, VI and VII are fragmentary per ‘ 'In Fig._ V the needle 50' is in its lowered position, 40 spective views showing how the fabric of Fig. I and the needle Si in its raised position.- During may be produced on a modified ?at___knitting ma chine of the “Cotton” type.‘ ' ~ 'Figs.

Incidentally-it will be noted from ’ V‘ Figs. XI, X11 and XIH are views like Figs.

Fig. IHV shows still another alternative form formation of the completed invert sinker loops of‘fabric generally like‘ the fabric of Fig. III; and 22. In Fig. VI, the needle‘ 50 is ascending, and Figs. XV, XVI-and XVII are views similar to the needle 5| descending. Incident to its descent Figs. XII-XIII showing how the fabric of Fig. XIV' in Fig. VI, the needle 5| engages the loop l2 of may be produced commercially. , _.the course 2 within its book and draws the same, In order that the construction of the different 2 2,129,385 through the loop II of the course I, after which the beard of said needle is depressed by contact with the supplemental presser bar 53. In Fig. VII, the needle 50 is raised to its highest posi~ tion, and the needle 5| depressed to its lowest position. In moving from the position of Fig. VI to that of Fig. VII,,the loop I2 is drawn through the loop I3 of the course 3 of the fabric and said loop I3 is cast from the needle 5| immediately 10 after the closing of the beard of said needle and the descent of the same below the knockover 55, which, by suitable means not illustrated, is po sitioned below the supplemental presser bar ‘53 inorder to sustain the loop I3 and thereby assist 15 casting thereof. As a consequence of the last described step, the loops I2 are completed in course 2 as shown in Fig. X. In Fig. VII, the needle 50_ is ready to receive new yarn Y for the knitting of another course of the fabric, and 20 the needle 5| ready to ascend after the m'anner described in connection with Fig. IV to repeat the loop forming cycle. From the foregoing it will be seen that a loop is first, formed by the needle 50 and thereupon cast from the latter and 25 caught by the needle 5I, this operation contin uing throughout the knitting of the fabric with the resultthat the sinker wale loops of the re spective courses assume transposed positions in line with the loops of adjacent courses. Any .30 suitable means ‘may be provided for actuating the needles 5!) and 5| and the knock-over bits 55 in the manner described. If the machine ex empli?ed be say of thirty-‘six gauge, (24 needles loops 32b connecting the needle wale loops I 2b and the corresponding sinker wale loops 22b lie in the intervening course 3b; and so on through out the fabric. Here again, the alternate wales of the fabric are formed of interlooped sinker loops which are inverted in respect to the loops of the other wales at the same side of the fabric as in Fig. I; with the addition however of lines of > half loops between the wales. A knitting machine arranged as shown in Figs. 10 IV-VII, but with an additional set of needles, that is to say, three sets of needles in- all, oper ated in succession will produce the fabric of Fig. II in the manner similar to that explained in connection with the fabric A featured in Fig. I. 15 The fabric C illustrated in Fig. III resembles the fabric described and claimed in U. S. Patent No. 1,981,471 in that thepcorresponding needle wale loops “0, I 30, I 50, etc. of alternate courses I0, 30 and 5c engage each other after the manner 20 of plain knitting; and in that the bends or bights of such loops overlie the shanks or sides of cor responding wale loops of alternate intermediate courses I2c, I40, I60, etc. likewise interengaged ‘ after the manner of plain knitting, with the 25 sides or shank of all the needle wale loops ap pearing on one face .of the fabric, and the bends or bights of all the loops appearing on the other face of the fabric. The fabric C however differs from the patented fabric in thatthe. sinker wale 30 loops 2|C—-25C, by virtue of being transposed to courses remote from the courses containing ‘the corresponding needle wale loops I Ic-—I5c, form distinct wales between the needle loop wales. gauge double that of the needles, namely, forty The sinker wales of alternate courses, it will be observed, are also engaged with each other after eight gauge. The fabric is furthermore charac terized by having, at one side thereof, alternate the mannef'of plain knitting with the bends or wales (the-sinker wales) wherein the loops are in- - bights of said loops overlying the shanks or verted in respect to the other (needle) wales. sides of the corresponding sinker wale loops of alternate intermediate courses, and with vthe 40 .The method of starting this knitting of the fab ‘ shanks or sides of said sinker wale loops all ap to the inch) it will be seen from the above pro cedure that the resultant fabric will be of a ric is as follows: A starting course, say a course 3 is ?rst formed on the needles 50 as shown in Fig. VHIa and the'sinker wales 23 of such course engaged with the hooks H of a hook bar B as in 4 . ‘ 5 the starting of any knitting on a ?at knitting machine. A second course 2 is then formed as in Fig. IXa and the needle loops I2 drawn through the needle loops I3 of the previous course 3, said 50 loops I3 falling back upon the needles 5I. A third course I is next formed on the needles 50 as in Fig. Xa with casting of the needle loops I3 of the course 3 from the needles and release of the needle loops I2 of the course 2 to-fall back onto 55 the needles 5|. This cycle is continuously re peated as described in connection with Figs.‘ VIII-X, the fabric being maintained under con stant tension with the result that the needle and sinker wale loops of the successive courses take positions as'shown. ’ - lathe fabric B of Fig. II, the sinker wale loops 2Ib corresponding to the needle wale loops Nb of the course Ib are disposed between the needle wale loops I3b of the course 3b; the sink 65 .. er wale loops 22b corresponding to the needle vwale loops I2b of the course 2b between the needle wale loops I 4b of the course 4b; and so on - throughout the fabric. The fabric B of Fig. II is further characterized by vertical rows of in 70 terengaging half loops 3lb, 32bv and 33b‘ interme diate the needle'and sinker wale loops IIb, I2b, I3b and ~2Ib, 22b, 23b. The half loops 3Ib con ‘ necting the needle wale loops I Ib and the cor responding sinker wale loops 2Ib, it will be ob 75 served, lie in the intervening course 2b; the half pearing on one face of the fabric, and the bights or bends of said loops all appearing at the other face of the fabric. Inthe fabric C, the sinker wale loops are transposed from the correspond 45 ing needle wale loops to other courses further remote than in the fabric of Fig. IL, Thus, for example, the sinker waleloops 2| 0 corresponding to the needle wale loops No of the course Ic lie between the needle wale loops I5c of the course 50; the sinker wale loops 220 corresponding to the needle wale loops I 20 of the course 20, be tween the needle wale loops I60 of the course 60: and so on throughout the fabric. The fabric of Fig-III may beproduced upon a 55 ?at knitting machine arranged as shown in Figs. XI-XIII, the machine having two sets of needles 50c and 5Ic; the usual presser edge 520 for the needles 50c; sinkers 54c; knockovers 550 to coact with the needles 500. The machine is further provided with toothed loop detaining wheels 56 and 51 in the plane of the needles 50c and 5Ic, said wheels being mounted on shafts 58 and 59 adapted for intermittent '_ rotation by ‘quarter turns in the direction of the arrows; a supple mental knock-over bar ' 530; a‘ supplemental 65 presser edge 60 forrthe needles5lc; and supple mental knock-overs BI to coact with the needles 5Ic. In Fig. XI, the needle 500 is about to de scend and in so doing takes a loop IIc for the 70 course Ic of the fabric C just kinked by the sinker 540. In continuing its descent, the needle carries the loop IIc downv through two previously formed intertwisted loops I20 and I30 temporar ily held in superimposed relation by the wheel 56, 3 - ‘ 7 _ ' 2,129,385 loop I3d falling back against the newly drawn and is in turn inter-twisted with the loop I20. in loop lld and the loop l5d. dropping onto the shank of the hook 5| d, which, in the meantime, 'nection with the ?rst embodiment of my inven has been advanced through the intertwisted - tion. When the'needle 500 has reached the posi- . loops l5d, Md and the- loop Hd'inreadiness to tion shown in Fig. XII, the wheel 56 is turned engage the loop l3d. ‘With the foregoing accon'ié and releases the-loop l3c.which fallsb'ackupon plished, the needle 50d moves leftward from the the needle 5lc, which,‘ in the‘ meantime has been position of Fig. XVI beneath, the wheel 56d and a manner identical with that described ‘in con .raisedfrom the position of ‘Fig. XI to that of . then upward-between said wheel and the presser Fig. XII and passed‘ upward through two pre- ‘_ edge 52d and lifts the loop I id to the level of the 10 viously formed andintertwisted loops I40, I50 knockover 5511 which advances from theposition temporaril held in superposed relation by the - of Fig. XVI to the position of Fig. XVII to hold wheel 51. n continuing from the position of Fig.. ’ said loop.

Immediately upon being released by the needle 50d, the loop I Id by virtue of the tension thereon is drawn laterally from ‘ teeth 56a:' and 51a! of the‘ wheels 56 and 51. Finally, the needles 50c and 510 move back to the positions shown inFig. XI to complete the loop ,the knockover 55d and caught by the vacant ’ forming cycle, which is continuously repeated. The fabric'of Fig. 111 is thus produced under the I ‘tooth 56y of the wheel 56d.
