Application filed October 19, 1905. Serial No. 283.515- .1 '1

T c all whom it may concern:

Be it .known that 1, ROBERT W. Soon, a citizen of the United States, residing in Leeds Point, New J ersiag, have invented certain Im-- .a machineknit fabric of this character in which the chan e from rib-stitch 'to plain stitch can be readily effected by manipulation of the needlesand without stopping the machine or re uirin'g the intervention of anattendaht, t e invention being therefore especially adapted for use in the manufacture of hosiery upon automatic knitting-ma-.

chines. v

In the accompanying drawings, Figures 1, 2, 3, and 4represent, on a much exaggerated scale, 'variousfabrics made in accordance with my invention. Fig. '5 is a, diagram 3 showing an arrangement of needles suchas may be used in a machinefor producing the character of fabric shown in Figs. 1, 2, and 4.

Fig.16is a diagram representing an arrange ment of needles such as may be used in a machine for producing fabric of the character shown in Fi 3. Fig, 7 is a vertical sectional view of su cient of a knittin -machine to illustrate the method of transfer of a stitch from a dial-needle to'a cylinder-needle. Fig. 8 is a similar view, but showing the arts in different relations to each other; and ig. 9 is a view of a special form of cylinder-needle which is sometimes employed.

In Figs. 1 to 4 of the drawings, arepresents lain-stitch wales which extend throughout.

0th the ribbed and(plain webs. b I) represent rib-stitch wales, an (i represents plain-stitch wales resulting from the union of'a' pair of rib-stitch wales b b. "Plain-stitch wales may be described as those having all of their stitches drawn to the face of the web and ribdrawn to the back of the web.

= In the fabric shown in Fig. 1, the wales b stitch wales as those having all of their stitches have rib' stitches in courses 1, 2, and 3, but

' change to plain stitches in course 4, and in the latter courserib-stitches of wales b are doubled with the plain stitches which supplant r -i the rib-stitches in wales b, all of the stitchesin 5 5 course 5 being plain stitches. In the fabric shown in Fig. 2 the stitches of the rib-wales b b are united in course 3, a single rib-stitch being drawn through these doubledstitchcs 1 in course 4 and these single rib-stitches being then transformed into plain Wale-stitches in course'5. Both of these fabrics are instances of two-and-two rib webs transformed to plain web, a two-and-two ribbed web, meaning one in which pairs of plain wales alternate with pairs of rib wales in the ribbed portion of the fabric, In Fig. 3, however,;1 have shown an instance of'a change frolnra one-azid-one ribbed web to a plain web,f one r; a'nd-one*rib be d web meaning web in which single, plain, and ribwales alternate with each other. In this fabric the rib-stitch wales .1) change to plain-stitch wales in course ,anid

in said course 3 .t-hc stitches of the rib-walsbc-g are carried across a plain-stitch walc aia'nd are doubled with the stitches which supplant the rib-wales b, all of the stitches drawnlin course 4 being plain stitches. 2 1

In the needle-diagrams shown in Figszi-5 and 6, tri'epresents cylinder-needles which'are 8 always in action, to rep rcscn ts cyl ind er-needl'es which'in knitting ribbed fabric are outroi action, but are in action, together with the needles w, in knitting plain fabric, and "y y represent dial-needles which are in action during the knitting of ribbed web, .but which transfer their stitches to the normally inactive cylinder-needles w in effecting the change from ribbed web to plain web and are then put out of action. 1 n In effecting the production of fabricsuch as shown in Fig. 1 the stitches are first trans:- ferred from the dial-needles i ,-Fig '5, to the cylinder-needles w, and sai (lial needlesfly are then ut out of action. After the at mationo a course of stitches 4, Fig. 1, upon the cylinder-needles, including the needles to, and upon the dial-needles y the-stitchesar' transferred fr om said diaLnecdle's 7 to the if. needles w, and said dial-needles y are then I00 put out of action. v In producing the fabric shown in Fig. 2 'a stitch is first transferred from a dial-needle y to a dial-needle y bvshogging said needle 4/ lateral] past the adjoining needle y and then projecting the latter-so that it can enter the stitch upon' the needle y. The needle y having engaged the stitch is retracted"and the dial-needle if is put out of action, and after the production of a course of stitches upon the cylinder-needles c and dial-needles .y the stitches are transferred from said dialneedles y to the previously-inactive cylinderneedles to, the dial-needles y are'put out of are first transferred from the dial-needles y,

' shown, for instance, in Fig. 4.

Fig. 6, to the cylinder-needles wthe dial'-. needles y are put out of action, a course of stitches is knitted upon the cylinder needles m w and upon the dial-needles y, and the stitches upon the dial-needles y are then transferred to the cylinder-needles w and the dial-needles y are put out of action.

After the first transfer of stitches from the needles y tot-he needles w in either machine sad the retirement of said needles 3 more than one course may, if desired, be knitted upon the cylinder-needles a; .w and dialneedles y before transferring the stitches from the latter to the needles w and putting them out of action, and in like manner any desired number of courses of stitches may be.

formed upon the cylinder-needles ac and dialneedles'y after transferring the stitches from dial-needles y to said needles y and putting needles 1/ out of action before transferring the stitches from the needles y onto the previously-inactive cylinder-needles w, or, on the other hand, a complete transfer of stitches may be made in one and the same course, as In the fabric shown in the latter figure stitches of both ribwales b b are united in course 3, and a single plain stitch is drawn through these united stitches in course 4.

In carrying out my invention various forms of machine may be employed; but in Figs. 7 and 8 I have shown suflicient of the elements of one form of machine which has 'proven effective in practice to impart a proper understanding of the method of manipulating the needles to effect a transfer of stitches from one to another. In these views 10 represents part of a needle-cylinder, and 11 part of a dial on the inside of the cylinder. The dial-needles y y are carried'by the lower ends of jacks 12, pivotally mounted upon a fixed ring 13, and having their upper ends acted upon by cams carried by a'cam-plate 14, this p ate having two sets of cams, one for acting upon the jacks for causing operation of the d ial-needles for ordinary knitting and another set for causing abnormal projection of the dial-needles, so as to carry them outwardly beyond the cylinder-needles, as shown. This has the effect of drawing or stretching the web, so as to dispose rib-stitches over the cylindersggeedles, as shown in- Fig. 7, so that said cylinder-needles may be projected and caused 'the-transfer-cains are disposed at to enter said rib-stitches, as also shown in said Fig. 7, it being understood that thedialneedles before being projected in the manner described have, if such movement is necessary, been shogged or moved laterally into line with the cylinder-needles'which are to has been to such an extent as to draw a precedently-formedrib-stitch over the cylinder-needle such lateral shogging of either cylinder or dial needle preparatory to the retraction of the dial-needle will not be-nec- 'essary, since the slacking of said precedentlyformed stitch on the retraction of the dialneedle will cause it to en age with the projected c 'lind'er-needle. n like manner a dial-neecle may after having been abnormally projected be shog ed laterally, so as to carrv it slightly beyond an adjoiningi dialneedle, and the latter may be. rojecte so as to engage the neighboring ial-stitchand' after engagement with the latter can be withdrawn, so as to permit of the shogging back of the transfer-needle and the retraction of the same to castits stitch.

In any of the machines used for my improved fabric the cylinder is, y preference, cut or grooved so as to present a uniform gage, whereby a correspondingly uni form age of plain web is insured, the spreading of the wales shown in the various views .of the drawings not being apparent'in the roducing finished fabric, as the contractile power of? the ribbed web causes its surface Wales to lie 4'1.

as closely together as those of the plain web.

My improved fabric can be knitted without arresting the operation of the machine and by the use of a continuous thread, it being understood that the knitting-cams 'and"'.

remote from each other that the knitting operation can be going forward 11 on certam of the needles of the machine whi e stitches are being transferred from and to other needles of the machine at a point more or less remote from the knitting-point.

My invention is not limited to a web composed of a single. continuous yarn, nor does the" term continuous? necessarily imply unbroken continuity, as yarns'of different color or character may be used in different portions of 'the web so long as the meeting ends of said yarns overlap or rovide for a continuous feed of yarn to need es of one and the same machine. Y

oints so "Vlhen the transfer of stitches is to be effected from cylinder-needles to dial -nee dles, said cylinder-needles will have butts or projections-such. for instance, as shown 9in order that when abnormall projected they will stretch the plainstitc wales to such an extent as to permit the dial-needles to enter and engage the same.

A fabric produced in accordance with my invention is distinct .from one in which the stitches of a ribbed web are run onto a lesser number of needles in a lain-knitting machine in the usual way, or in the ordinary method of runnin on the doubling of two stitches of the rihbed web onto a single needle of the plain-knitting machine is a haphazard operation, and such doublings are conse uentlymatters of chance and are therefore iiistributed without any regard to uniformity of s acing throughout the. web, whereas in a fa ric produced in accordance with my invention the sin le wales of the plain web produced by doubiing wales of the '25 ribbed web are disposed at uniformly-spaced intervals throughout the web. A further distinction between my improved fabric and onemade by running on in the usual manner is that in my fabric there is a continuous yarn common to both webs, whereas in the ordinary fabric the plain web is necessarily knitted with a yarn independent of that of which the ribbed web is composed.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. A machine-knit fabric, partly ribbed and partly plain, and having in the ribbed web wales in excess of those in the plain web, standing wales in both webs, and a plurality of wales of one web continued as a single wale of the other web at uniformly-spaced intervals throughout the web.

2. A machine-knit fabric, partly ribbed .and partly plain, and having a continuous yarn common to both webs and having also in the ribbed web wales in excess of those in the plain web, standing wales in both webs, and a plnralitv of wales of one web continued as a single walc of the other web.

3. A machine-knit fabric, partly ribbed and part1} plain, and having in the ribbed web wales in excess of those in the plain web, standing wales in both webs, and a lurality of wales of one web inde endent j" interknitted with, and continued as a single wale of the other web.

4. A machine-knit fabric, part1 ribbed and partly plain, and having a continuous yarn common to both webs and having also in the ribbed web wales in excess of those in the plain web, standing wales in both webs, and a plurality of wales of one web inde endentlv interkni-tted with and continue as a single wale of the other web.

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

ROBERT W. SCOTT.
