I Application filed June 17, 1910. Serial No. 567,507.

To all whom'z't may concern:

Be it knownthat I, ROBERT W. SoOTT, a citizen of the United States, residing in Leeds Point, Atlantiocounty, New Jersey, have invented certain Improvements in Shaped Knitted Webs, of which the following is a specification."

he object of myinvention is to provide a simple and efficient means of shaping a knitted web and particularly a seamless tubular web, an Object which I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in

which' v Figure 1 rs a new of "a piece of seamless tubular ribbed lmitted web intended for the illustration of the knitting instrumentalities of a machine arranged for producing the wider portion of the fabric, as shown in Fig. 2; Fig. 6 is a similar view of said knitting instrumentalities as related to each other for the production of the narrow portion of the -web,- shown inFig. 3; Fig. 7 is a similarview of said knitting instrumentalities as modified in their relation to each other for the production of the web shown in Fig. 4; Figs. 8, 9 and 10 are views, similar, respectively, to Figs. 5, 6 and 7 but illustrating a modification of my invention.

The object of my invention is to effect 'changein the diameter of the tubular web so as to contract said web, as, for instance, in

the waist portion of a shirt or the, ankle or garter portion of a stocking, or to increase the diameter of the web as'for instance in the bust or skirt portions of. a shirt or the calf portion of a stocking.

My invention consists mainly in employing, usually in the wider portion of the garment, a composite web and in'an. adjoining.

portion of the garment, usual1y the narrower portion, a' web Of difierent character, usually a single web having fewer wales than the composite web but knitted continuously with the standing wales of said composite web, a special adaptation of my inventlon being that in which the web both in the composite and single portions is ribbed.

As shown in Flgs'. 1,2,3 and 4, I have employed, .in the wider portion .of the garment, ribbed knitted web Of the character set forth /in my Letters Patent No. 899,439, dated September 22, 1908, to which I have given the name interlock rib, the character of the web being changed to ordinary rib in the narrowed portion of the garment.

As shown in Fig. 2, the portion A of the web is composed of two ribbed webs with crossed sinker wales, one of these webs pre senting alternately produced face'wales 1 and back wales 2, and the other presentin alternately produced face wales 3, and bac wales 4, the sinker wales of one webcrossing those of the other web. In the contract ed portion B of the garment, however; ordinary ribbed web is produced, this web in the fabric shown in Fig. '3, consisting 0 an ordinary one-and-one rib presenting a1ter-' na'tely produced face wales 1 and back wales Patented Apr. 11,1916.

2, while in the fabric shown in Fig. 4, the

contracted portion of the web presents a two-and-one rib, adjoining facewales 1 and fabric, the needles 1 and 3' being hereafter,

for convenience referred to as cylinder needles and the needles 2 and 4 being referred to as dial needles, as they "will usually be disposed respectively in a. cylinder and dial in a circular knitting machine, although my invention in its broader embodiment is not limited to seamless tubular webs or to the use of a circular machine.

.The two webs are independently knitted,

the yarn being fed to the needles 1 and 2* in order to produce one web and to the needles 8, and 4 in order to produce the other web, and to cross its sinker wales with that of the first web, as indicated by the plain and dotted lines in Fig. 5.

In order 'to' change from the production of thisinterlock ribbed web to an ordinary one-and-one ribbed web for the contracted portion. of the garment stitches, are trans! ferred from the dial needles of one 'set to the cylinder needles of the other set, and

e 'linder needles of one setto the eedles of the other set, for instance, the e l-.3" may be transferred from the dies to the cylinder needles P and cm the cylinder needles 8* to the disl needles 2, the needles from which the stitches hove been transferred being then put out of action and one-end-one ribbed web knitted npon the remaining cylinder needles 1 and dial needles 2, as indi ceted in 6, thus producing e one-andbbed web having one-he d the number ot the interlock ribbed Web.

nter number of wales in the con" portion of the'germent is desired, lisng'e may be from the composite ribbed web .0 ordinary two-nnd-one ribbed web havin l' ee-fourths as many wales ss there are in t .c composite ribbed web, this change by transferring stitches from every other dial or cylinder needle to the corresponding cylinder or dial needle and one needle carrier in respect ther, so that the remaining active J needles of one carrier will alternate with active of needles of the other carrier, :or instance, the stitches may be transferred rom the dial needles 4? to the cylinder needles l and the dial then shogged so as to cause the needles 2 to alternate with the tiv - pairs or needles 1* and 3*, as shown in Fi l i", the niting yarn rollowing the course shown in said figure.

lit in not necessary that the composite ribbed web shell be one-end-one rib sis-some or all of the ribs of each member of said web may be composed of e plurality of Wales, thus in Fig. 8: I have illustrated an arrangement of knitting instrnrnentnlities for the production of a composite ribbed web, each member of which is composed of tWo-end-two rib. In order to chenge this web into web having one-half the number of wales, two out of three of the needles or one needle carrier may transfertheir stitches to the corresponding needles of the other needle carrier, the third needle in the latter errier transferring its stitch to the corresconding needle 01" the other needle carrier, in 9 stitches have heestrensferred irons third cylinder needle 5 to every l oni every third cylr needle 6 to every third dial 8",

.' every "hird cylinder needle 7 to every hel needle 5 and iron; every' third stitches hole the on ones to remain in i, the stitches b transferred from c dial needles to the corresponding c'fnder needles and said disl needles being '1, of scti'on; the knitting rern being in Fig. t n it is desired to produce a. two-endn to every third ditil needle di'il needles which thus receive the upon the nce lles in manner rus es one web haying three-fourths of the number of wales of the composite 'ribbedwcb produced shown in Fig. the stitches transferred from Very other needle of one needle carrier to the corresponding needle of the other needle carrier, and the needle carriers are then shogged so as to bring the remaining needles of one needle carrier between successive pairs of needles of the other needle carrier, thus, as shown in Fig. 10, the stitches have been transferred from every other needle 5 and 7 oi the dial to the corresponding cylinder needles 5 and 7, and the dial has then been shogged so as to bring the needles 8 between the needles 6 and 7 of the cylinder andthe needles 6 between the needles 5 and S of the cylinder, the yarn being applied to the needles in the manner indicated in Fig; 10. 7

When the dial needles are normally in line with the cylinder needles transfer oi stitches from the needles of one carrier to those of the other can. be eil'ec'ted by What 1 term straight transfer and in making suchtransfer it is preferable to so manipulate each trsns'ferring needle as to transfer the stitch oi 2i, course preceding that carried by the needle, or when this is not done, the stitch which is transferred, is, by preference, that of s coursennderlying the conrse upon the needles which receive the transferred stitches.

- In changing from the narrower to the wider portion of the web the needles which transferred their stitches in effecting the narrowing are reintroduced and resume the formation of stitches for the further prodno'tion of composite ribbed web, no eyelet holes being produced for the reason that the open loops in the initial coursejiiormed on the reintroduced needles are covered by may, if desired, be cast from the needles,

the standing wales of the web preventing the straining of the Wales trom which the stitches were dropped to such an extent to cause said stitches to run back.

, 1 1 claim:

1. A knitted web ribbedthronghout and ha ving contiguous portions, one composed of sepiir'ate webs interknitted with one another and the other composed of a single ribbed web, wales of the composite web being discontinued at the point of change.

2. A knitted web ribbed throughout and having contiguous portionsfone composed oi separate llblOGCl' webs interknitted with one another and the other composed "of a single ribbed Web hovlngstswsles started by merging wales of one member of 'the com posite ribbed web into corresponding wales or the other member of the some.

3. The mode herein described of produc-i ing a knitted fabric said mode consisting in "first knitting a composite web upon a plurality of sets of needles by first drawing stitches with one yarn upon one set of-nee- (lles, then drawing stitches with another yarn upon another set of needles and interlocking these stitches with those first'produced, then discontinuingthe formation of stitches upon certain of the needles and transferring the stitches upon the latter to needles which still remain in action, and

stitches first upon-one set of needles with one yarn and then upon the other set of needles with anothenyarn so as to interlock the two .ribbed Webs'one with the other, then discontinuing the formation of stitches upon the needles of one set and transferring the last formed stitches upon said first set to corresponding needles of the other set, and then producing stitches upon the latter set of needles only.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
