.in themanner hereinafter set forth, reference being` had to the accompanying drawings, in which- Figure 1 isan` exaggerated View of a piece of 'ribbed knitted web produced in accordance with my invention; Figs. 2 and 3 are diagrams illustrating the arrangement and eperation of instrumentalities whereby ribbed knitted webs in accordance with my .invention can be produced, and Figs. 4, 5 and 6 are perspective vlews of certain of sald m strumentalities.

' In Fig. 1 of the drawing, a' represents the vneedle wales of the ribs on one face ofthe web, and al represents the needle Wales of the ribs on the other faceof the web, thus the wales a maybe those produced by the needles of the cylinder of an ordinary circular rib lao knittingmachine, and the Wales a1 may be those produced'by the dial needles of such a machine, b'reprsenting the sinker lwales or portions of the-knitting yarn passing from one needle wale to the other of the ribs of either face of the web and b1 re 'resenting vthe sinker wales passin from need e wales ofthe ribs of one v.face of t e .web to needle wales of the ribs of the other face. of the same. In order to better distinguish the wales from each other, I have, in the drawing, shown the stitches of one face of the web in heavier lines than those. 'of the other face. It will be the formation of eyelet holes between ,the

needle'wales of the rib at definite intervals, such eyelet holes being produced by transfer of sinker Waleloops into adjoining lneedle wales, the eyelet holes being formed in the ribs of but one face. of the web, the ribs on the other face of the web being normal.

The disposition and' manipulation of the instrumentalities'for effecting the production of eyelet holes of the' character shown in Fig. 1 will be understood on reference to Figs. and 3, in which w represents cylinder needles for producing the wales .(1. of the fabric, g/ represents dial needles for producing the wales a* of the fabric, and erin Fig. 2 representsaJ transfer point for producing elongated sinker Wales and transferring the same to aduioining standing wales. The

transfer point consists of a stem 1 having an outer end 2 in the same plane as thestem, a diagonally inclined portion 3 and a short sub-stem 4 connected to the stem 1 by a neck 5 substantially at right angles to said stems 1 and 4, the diagonal member having, near itsvinner end, a shoulder' 6, as shown in Fig. 4. The stems of these transfer pointsy are guided in grooves in the dial midway hetween the needle grooves of the same.v In order to effect transfer of a sinker Wale between adjoining needle' wales a e to one of saidneedle Wales, the transfer point isfirst projected until its outer end 2 occupies aposition between the adjoining cylinder needles either before or after the projection of the needles to receive the yarn from the yarn guide. Vhen the needles are retracted in order to engage and draw stitches of the knitting yarn the sinker Wale yarn will be engaged and held by the outer end 2 of the transfer point, and the latter may retain this position for one or more coursesofthe knitting until as many sinker Wale loops as may be desired have been deposited upon the end 2 of the point, the fabric shown in Fig. 1 having loops of two successive courses thus caught and retained although but one loop or more than two may be thus acted upon.l When itis desired to transfer the sinker Wale loops the transfer point is projected so as to bring the inclined member 3 of the same into action upon said loops, thus causing the lateral displacement of the same as well as a slight outward displacement due to the action of the shoulder 6 thereon, the parts being now in the relation to cach other shown in 2. The transfer' point remains 'in its projected position until the receiving needle has -been projected to such an extent as to enter the sinker Wale loop or loops which have been deflected into the path of said-needle, whereupon thefullwithdrawal of the transfer point releases the lo'op or loops and causes the same to engage the needle so that in the next course of the knitting the new stitch will be drawn not only through the stitch already upon the needle but also through the sinker Wale loop or loops previously de -posited upon said needle.

`In order to effect lateral spreading of a smker Wale loop orplurality of loops to engage a needle Wale on each side of thesame,

as shown in the bottom row of Fig. 1, I may.`

- hooks of the needles 'to spread said outermembers so as to pass between them when' the transfer point is retracted,' and the same being true of the double transfer points shown in Fig. 5.

The eyelet holes may be produced in` any desired sinker Wale courses of the Web, a plurality of plain sinker Wale courses intervening between those sinker Wale Acourses' in which transfers are effected and a .plurality of needle wales 'intervening between the sinker wales in which transfers re eiiected.

In Fig. 1 of the drawing, I have shown my invention as applied to a web having a twoand-two rib butl it will be evident that it is applicable to ribbed Webs of any character having a `plurality of needle wales in ribs of either face in'which the eyeletholes are to be formed, and either single or multiple wales in the ribs which are not to be thus distended, preference beinggiven to webs having an' even number of needle Wales in theribs, in order that the eyelet vholes may occupy a central position in the ribs in which they are formed.` f

The production of eyelet holes ina certain course or courses of a ribbed web has the effect of expanding the web to some extent at said coursewand this reduces to aA corresponding degree the elasticity of this portion of the web` In order to'lessen this expansion without corresponding lessening of the number of eyelet holes formed inthe `web I prefer to form the leyelet holes of successive rows in different wales, thus the eyelet holes 'of the first row in the Web shown in Fig. 1 are formed in the wales marked bm while the eyelet holes of the second row are formed in the wales marked lm. l

Independent of the ornamental effects'4 dueto the expansion-and contraction of the ribs of the web, eyelet holes, when formed'in 65 A the ribs constituting the outer face of a garment', serve their intended pu ose better than eyelet holes formed in a p ain'web orbetween the ribs of the two faces of a rib'bed web, because the needle wales between which such 'eyelet holes are formed are supported freey from contact with the person of the wearer of the garment.

I claim l. 'A knitted web havin on either face, 75 i A ribs, each composed of a p urality of needle" wales, said ribs having eyelet holes formed therein by displacement of sinker Wale loops between the needle wales of which the rib isl l composed, said displaced sinker Wale loops 80.
