KNITTED FABRIC.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed April 8, 1909. Serial No. 488,543.

To all 'whom it may concern:

Be it known that I, ROBERT WV; SCOTT, a citizen of the United States, residing in Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in Knitted Fabrics, of which the following is a specification.

My invention relates to knitted fabrics Icomposed in part of ribbed web and in part tionable because a laterally displaced stitch does not present itself in the best position for the entrance of the needle to which it is to he transferred.

The object ofmy present. invention has therefore been to overcome this objection in effecting such doubling transfers and at theV same time to make a less abrupt change in the width of the .web at the point where the Wider web joins the narrower web.

In the accompanying drawings-Figure 1 is an exaggerated view of a piece of Web knitted in accordance with my invention, in which a change is effected from two-and-two ribbed web to plain web having a lesser number of wales; Fig. 2 is an exaggerated view ofa piece of web in which change is effected in accordance with my invention from a one-and-one ribbed Web to plain web having a lesser number of wales;A Figs. ,3, 4; and 5 are diagrammatic representations of the different dispositions of the needles resorted to in knitting the web shown in Fig.v l, and Figs. 6, 7 and 8 are diagrammatic representations of the different dispositions of [the needles resorted to in knit-tingV the web {f sh'own in Fig. 2.

Myinventioncanbe practiced upon any I V type of rib knitting machine provided-With means for shogging the needles of one set 'in respect to those of the other set so as for transferring stitches from needles of one set to needles`of the other set, and with means for independent control of the needles in the manner hereinafter set forth.

Usually my invention will be practiced in' connection with a circular rib knitting machine having the needles for. producing plain web contained in the cylinder and the ribbing needles contained in the dial, hence, for convenience, I will, in my specification and claims, refer to the plain web needles as cylinder7 needles and to the ribbing needles as dial needles, without, however, intending thereby vto limit myself to a machine of this type.

As 'an instance of a machine which, without much change is adapted for the carrying out of my present invent-ion l may refer to that forming the subject of my Letters Patent No. 834,763, dated October 30th, 1906.

The main difference between my present invention and previous inventions of its with the standing Wale but a subsequently produced stitch, the object being to permit the stitch which is actually transferred to be drawn out straight over the receiving needle instead of being pulled diagonally across the same, as -it must be when the transferred stitch is the shogged stitch.

In carrying out my present invention one or more, and preferably a plurality, of stitches are formed upon the shogged dial needles while the same occupy their new relation to the cylinder needles and before effecting the transfer ofthe stitches from the dial needles to the cylinder needles, and in effecting the transfer the dial needles are preferably projected to such an extent as to draw into line' with thereceiving needles the stitches of the course preceding that actually carried by said dial needles, both the preceding stitches and those cast from the dial needles being caught by the receiving cylinder needles when said dial needles are retired, this having been found in practice to be the best 'method of effecting the transfer, valthough in carrying out my invention it is not absolutely necessary to resort to this method, as but one course vof ribbed web may be formed upon the needles when they occupy their new relations, the stitches upon the dial'needles being transferred vto v t b, c and By preference, ltwo of each of the receiving cylinder needles. In either case the stitch to be' transferred will, on the projection of the dial needle be drawnout directly over the receiving `cylinder needle, there being no tendency to lateral deflection vof said transferred stitch, because the stitches upon the cylinder needles on each side of the dialneedle-exercise 'substantially the same. degree of lateral. pull-fuponthe dial needle stitch.

In Fig. Laf'and bf represent the standing Wales which continue throughout both the ribbed and plain webs, mf represent Wales which are rib wales in theribbedweb landplain Wales in t'he plain Web, and 'y' repre--V sent wale'swhich appear only lin the ribbed y web, the Wale bbeing the same throughout, the rib Wale y being doubled intothe standing Wale a., and the rib Wale beingjdoubled into a freshly started yplain web Wale 0'.'

In producing the two-and-two ribbed portions of this web the needles are disposed as shown in Fig. 3, the web being produced upon the cylinder needles aand b, and upon the intervening dial .needles :c andy, empty and inactive cylinder needles c 4being interposed between lthe dialneedles m andy'of each pair. l

The first step in the transfer operation'is to shog the needlesw and y into line respectively with' the needles c and a, as .shown in Fig. 4, and two independent and interlocked ribbed Webs are then produced, Y, one a one-V and-one rib upon the needles and. (L, and. the other a tWo-and-one rib, upon the needles these independent courses'are thus knitted, and the stitches upon the needles y as Well as the stitches of the precedingcourse are then transferred to the needles a, and the like stitches ,are transferred from the needles zu, to the'needles c, th'e needles and gj being lthen retired from action and plain Web knitted upon'the cylinder as shown in Fig. 5.

. In the web shown in Fig. l', m2 and y2 represent the stitches upon the needles .and gf at the time they are"shogged, w3 and 'f1/f3 stitches of the frstcourse knitted upon the needles a, '22, and c,

needles and g/ in their new relation, m4 and y* stitches ofthe secondcourse produced upon said needles w, y, in such new relation,

and c2, c3, a2, a3 and b2, b3 respectively the.

first and Second stitches formed upon the needles c, a and b in the new relation, both stitches w3 and being transferred to the needles'c, and both stitches ya and ybeing transferred to the needles a preparatory toA the productionof plain Web. In this Web a thirty-threeandfone-third per-cent. doubling is effected, that is to say the'ribbed web has thirty-three-and-one-third per y cent. more Wales than the plainweb.` Y

`In the web shown inv Fig.`2 va somewhat similar method of transfer is adopted in connection with a web in which change is effected from a one-and-one ribbed web to a plain web. In this web a and b represent the standing wales which continue through- 'out both the ribbed and plain webs, and aj and y the wales which'appear only in the lribbed web, the wales w being. doubled into the standing wales a and the Wales y being doubled into the standing wales 'b'. In producing this'web the dial needles primarily `alternate in regular order. With the'cylinder needles, as shownin Fig. 6, and ordinary one-and--one'ribbed web is'produced upon" the needles While they are in such relation.

The first step in the transfer operationis to shog the' dialneedles, so that the needles a' will be in line with the cylinder needles a,

and the needles y'will be in line With the cylinder needles b, as shown in Fig. 7 and two independent and interlo'clred ribbed webs are then produced,.a course of one-andoneribbed web being first knitted upon the needles 'b and a", and a course of one-and-one ribbedl web being then Vknitted uponA the needlesv aand y, as shown in Fig. A7, each of these courses being then, `byjpreference, followed byl a second course, after which, the

needle stitches and those just preceding them l are transferredV from the needles. a: to the needles a, and from the needles y to the needles b, the needles and g/ being then retired from 'action and plain Webbe'ing prof' duced upon the cylinder needles and as indicated in -Fig. v8. This produces. a Web` in which there is a one-hundred per cent.

doubling, there being` twice as many wales in -the ribbed web asin the plain web. In Fig.

2 the stitches are'designate'd in the same manner as in Fig. l.

-' In both of he fabrics which I have showin the stitches transferred from the dial to the cylinder needles are subseand describe quent 1 to the laterally displaced .stitches caused bythe shoggingvof the dial needles and each transfer is 'what I term a straight 1 transfer caused by direct 'outward movement of the transfer needle" over-fthe receiving needle` instead of a doubling transfer"effectl 4 ed by a compound.movementfofthe transfer needle which sl1 'ogs. or `laterally' deflectfsa ceiving needle. {In'bo'th of the fabricsshown and described, m orec ver',lthev changefroln one'character of'web yto, the othersis effected through the medium vof an` intermediate Web'-v of a` characterdiiferent from that-'of either "5 is eh'ected'- through thel intervention'v of 'twd and in the web shown in Fig. 2 change from one-and-one ribbed web to plain web is ef' `fected through the'intervention of two independent one-andone ribbed webs. By reason of the plurality ofcourses of stitches contained in the intervening web, the reduction in the width or diameter of the web is effected less abruptly than when the shogged stitches are directly transferred.
