l webs, and a special object being to produce an effective eyelet hole in ribbed knitted webs.

.In the accompanying drawings: Figure 1 is an exaggerated view oi a piece of plain knitted Web'having eyelet holes formed therein in accordance with my invention; Fig. 2 is an exaggerated view of a piece of ribbed knitted web embodying the invention; Fig..3 is a like View of 'a piece of plain web illustrating another method of forming eyeletholes therein in accordance with my invention; Fig. 4 is a diagram illustrating the arrangement and operation of certain instrumentalities for the production of leyelet holes in accordance with my invention; and Figs. 5 and 6 are views illustrating said instrumentalities.

In Figs. land 3 a represents the needle wales of. which the fabric is composed, end in Fig. 2 a represent the needle 'wales of one face of the web which may,

for instance, be,v those produced upon the .cylinder needles of thei'ib knitting machine, and 'b represent the wales of the other face of the web, which may be those produced'uponthe dial needles of the machine, the web shown inthis figure constituting what is termed al two-and-two rib', that is to say it has pairs of cylinderneedle wales alternating 'with pairs of dial needle wale'sythe stitches constituting the wales b in the drawing being composed of heavier lines than those constituting the wales a in Vorder to better distinguish the wales from one another.

To produce 'leyelebholes in the knitted .web in accordance ywith my present invention stitches of adjoining needlewales are transferred one to the right` `and the other to the leit'into the wales adjacent therei to, as represented 'at c and d, and the formation of the then resumed. This resumption may be effected in different ways, for instance, after the transfer of Athe stitches from the two Walesinto the adjoining wales one of the needles may lirst be brought into action `to form the loop e as in course 5, and the other needle may subsequently be brought into action to form the loop f as in course 6, or both needles may be brought into action to form a loop g as in course 9 while in course 10 oneof the needles draws its stitch throughsaid loop but the other receive the knitting yarn Without casting preceding course.

the loopupon it so as to formthe extra loop i, this needle casting both of the loops g and 1I when it drawsv i'ts first full stitch asin course 11, or, instead of remainingin action after receiving the initial loop g the second needle may be held out of action while the other needle is drawing its first full stitch, as in course 10, Fig. 2, the

` first full stitch upon the second needle being drawn in courseell. This method of manipulating the needles, however, disposes a sin'ker 'Wale 'm across the top ofthe eyelet hole and hence is not considered as advisable a methodes that represented in '

courses

9, 10 and 11 in Fig. 1 in which theupper portion oi ithe eyelet hole is entirely unobstructed.

Still another method oi introducingthe needles singly but simultaneously after the transier of the stitches therefrom is that represented in Fig. 3 in which the first of the ytransfer needles is caused to draw a loop e as in course 5, While the otherneedle has transferred to it a loop 'n derived from the adjacent sinker walein a The disposition and manipulation of the instrumentalities for producing eyelet holes in the manner de scribed will be understood on' reference to Fig. 4, in which :z: represent cylinder needle?` for producing the Wales a of the web, and w represent Vtransfer points for conveying stitch'es from adjoining wales oi the web to wales on each side of the same. Each transfer point tu ,has 'a stem 1, an outer end'2, inline therewith, a diago- Rally inclined or stitch-deiiecting portion 3 with shoulder LLat the base ofthe same, a short sub-stern 5 parallel with themaiu stem, and a transverse neck 6 connecting said sub-stem to `the-main steni (see Fig. 5). Each needle from which a stitch is to lie transferred should be lprovided with a shoulder or offset which, when the needle is projected to an abnormal elevation, will engage 'and stretch the stitch last formed kupon said K proper position for the entrance of the outer endofthe transfer point. Continued movement of said 'transfer point then brings the stitch under the influence of the diagonally inclined member 3 oi the point, with the result that the yarn constituting oneside of the stitch'is deflected laterally to such an extent as to-overlie thev V`plane of movement oi .the next adjoining needle x, as

shown inFig. 4, said needle being then projected into position to engage the' deflected portion of tlie stitch, whereupon the transfer point is retracted, the transfer operation being completed by withdrawing 'the needle lupon which the stitch was originallygformed, so as toy cast o said stitch.

los

When it is not considered important to dispose the stem of the transfer point in line with the outer end oi the same, the said stem may form a continuation of the sub-stem 5, the transverse neck being dispensed with,

or the stitches maybe transferred from one needle to another by using needles such as shown in my Letters Patent No. 834,763; dated October 30, 1906, each needle having a stern at an angle to its shank, and the stitch to be transferred being deflected laterally to the desired extent by Aa lateral shogging of the needle after the same has been raised so as tov be free from the control of the cylinder.l

yThe formationV of an eyelet holerina ribbed web by transferring stitches from both wales of a rib of one face into adjoining wales of ribs of the other face practically discontinues the rib at the point Where such transfer is eected, and this is believed to constitute a novel idea in that class ofribbed webs which have eyeletholes formed therein.` l

1. A knitted web having stitches of adjoining needle wales transferred into wales on each side of the same, thereby forming an eyelet hole.

2. A knitted Aweb having stitches of adjoining needle wales .transferred into wales on each side of the same, thereby forming an eyelet hole, `said wales beginning again independently ot one another.

3. A knitted web having stitches of adjoining needle wales transferred into wales on each side of the same thereby forming an eyelet lrole, said wnles beginning again by means of a loop having a stitch of one wale drawn through in one course and astitch of the other Wale drawn through it in a succeeding course.

4. A knittedvweb having stitches ot adjoining needle wales transferred into wales on each' side ofthe same, thereby forming `an eyelet hole, one ot said 'wales being started again by a single loop having a stitch drawn through it in one'conrse and the other Wale beingstnrted again by a double loop having a. stitch drawn through it in a succeedingcourse'. y
