Application filed September 22, 1916. Serial No. 121,663.

design worked into it retains its closeness and furthermore allows of innumerable designs to be produced thereon. .I achieve this object by placing the loops selected for the design diagonally, relatively to the direction of the normal loops and across the adjacent loops of normal position. By the latter feature the loops forming the design are slightly raised out of the face of the fabric, whereby a good prominency of the.

design is obtained in conjunction with the feature that the loops used for the formation of the design digress from the direction of the loops of normal position.

It is a further object of my invention to provide a method for producing frame work knitted fancy fabrics of the character and features hereinbefore described.

lVith these objects in view, I have illustrated some practical embodiments of my invention by way of example, in the accompanying drawings which form a part of the specification.

Figures 1 to 3 illustrate, in a diagrammatical manner, the formation of the design; while in Figs. 4 to 7 some of the designs are shown which can be produced by my invention.

Referring to the drawings, Fig. illustrates an ordinary plain course of loops a,

y 01 f7 ajb 117 the loops designated 0, (Z, and g, h, are selected for the formation of a certain design. The numerals 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 designate needle books of a straight bar knitting frame. f, g, h, i, is, hang upon the needle hooks 1, 2, 3, i, 5, 6, 7, 8, 9, 10,. In proceeding to produce the designs, the loops attached to the 10 are divided into three grou s; one group, comprising the loops d an h, being allotted to the formation of the design, a further group, comprising the loops 0 and g and being situated either'on being assumed that The loops a, b, 0, d, e,

the right or on the left of the loops of the first group, are selected to be transferred to cross the 'loops of the first group, while the third group comprises the remaining loops a, b, e, f,i, is. In producing the design, the

loops of both of the groups last named are 1 synchronously detached from their respective needle-hooks and shifted in the same direction, but for varying amounts, so much so that after the transference the loops 0 and 9 Will extend over and, hence, cross the. loops at and h which have not been taken off their respective needle-hooks. The crossing obtains on the rear of the fabric; see Fig. 2. The remaining loops a, b, e, f, i, is have only been shifted sufficiently to provide for the needle hooks 5 and 9 to become free to recelve the loopsc and 9,- while the needlehooks 2, 3 and 6, 7 and 10, 11, which also became temporarily empty, are now charged again so that no gaps are produced, as will be apparent from Fig. 3. It follows that for the production of this exampleof a design,

the loops 0 and g contributin to the formation of the design, are shifte for the space of two needle divisions, while the remaining loops at, b, e, f, i, and is are shifted but one needle division, terrupted course of loops occupying, as initially, an unbroken series of needlehooks; the consecutive order of the loops} being the same again,'except for the loops crossing each other which have exchanged their places. In Fig. 2 the shifted loops are shown in an oblique, position in order to more clearly illustrate the steps of the method employed, Fig. 3 reproducing the proper position of the course, for the shift to which a part of the loops is subjected extends to the entire fabric. After the per in order to obtain an'unlnformance of'the shift the columns of loops I are again disposed vertically as initially, compare Figs. 1 and 3; with the exception of the loops 'contr of the design which. loops now cross each other symmetrically.

In consequence of the fact that theloops ibuting to the formation I forming the design digress from theposition- I I I designs -may be produced by this invention,

by altering the relative position of adjacentloofp 1 between superposed courses.

' simple designs are reproduced in Flgs. 4 to crossings, both within the same course loops and Some such 6. In Fig.4 two adjacent loop crossings are placed side by side and the loop crosslngs of superposed courses form vertical co umns, while in the design reproduced in Fig. 5 two adjoining loop crossings of .su-

erposed courses form oblique columns. In v ig. 6 a design is shown, in which single loop crossings of superposedcorurses form zig-zag paths; while in Fig. 8 another va- 'r1ety is shown in which the number of loop c'rossmgs changes from course to course. In

1 the same manner the adjacent loop crossings of superposed courses may be composed to form figures of any shape and contents.

For carrying my present invention into effect any of'th'e well known mechanism designed for the production of top machine patterns will be found useful, such mecha nism usually comprising two bars having I covering needles and belng adapted to be from the closely 85' shifted longitudinally and independent of each other.

What I desire to secure by Letters Patent of the United States, as my invention, is:

1. A knitted fabric comprising a closely woven bed of straight loops and having pairs ofa jacent loops inclined relatively to' the straight loops and crossing, said crossed loops providing a pattern projecting woven body formed by the straight loops.

2. In the manufacture of frame work knitted fancy fabrics, the method of producing figures, consisting in laterally shifting within a course ,the loops not contributing to the formation 'of the figure to empty -needle-hooks disposed between adjacent por-- tions of the figure. I 3; In the manufacture. of frame work knitted fancy fabrics, the method of proname.

I ducing figures, consisting in laterally shifting within a course the loops not contributing to the formation of the design'to empty needle-hooks disposed between adjacent portions of the figure, and one of the figure forming loops sothat the same crosses the associated loop not shifted.

4. In the manufacture of iframe Work knitted fancy fabrics, the method of producing figures, consistin in allotting loops to the formation of the gure, and shifting the remaining loops to needle hooks disposed between adjacent portions of the figure and transference of said'loops, and shifting one of said design forming loops so that the same crosses-the associated design forming loop.

6. In the manufacture of. frame work figures, consisting in allottiifg groups of loops to the formation of the figure, shift-- ing the remaining loops toneedle hooks disure andwithin the same course, said needle knitted fabrics, the method of producing posed between adjacent portions of the fig hooks becoming temporarily empty during the action of transference of said loops, and

' shifting one part of a group of said figure forming loops so that the same crosses the other part of the same forming loops. 4 p
