' i lj ti n filed June 21.1906. Serial No. 822.735.

T0 at whom it may cancer/1 Be it known that I, ROBERT VJ. Soon, 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 that class of knitted fabrics in which ornamental open-work effects are produced by the formation of eyelet-holes in the knitted web, object of my invention being to produce such eyelet-holes without the necessity of transferring stitches of one needle-wale to an adjacent needlewale, my improved web being one which can be produced upon a machine having ordinary latch-needles instead oi the spring-beard needles usually employed in machines for making this character of fabric.

In the accompanying drawing, Figure 1 is an exaggerated view of a piece of knitted web, illustrating the manner of forming eyeletholes in the same in accordance with my invention; and 2 is likewise an exaggerated view illustrating the arrangement and manipulation of the needles of a knitting-machine whereby such eyelet-holes can be produced.

Referring in the first instance to Fig. 1 of the drawing, a a represent the needle-wales of the fabric produced by the stitches drawn by the needles of the machine, and 7) b represent the sinker wales or portions of the knitting-yarn passing from one needle-Wale to the other over the sinkers or partitions between the needle-grooves of a l-n1ittingmachine. In order to produce an oyelet-hoie in the web, I displace the sinker-Wale yarn at the point where the eyelet-hole is to be produced and cause it to engage either with one of the adjoining standing wales, as shown at c in Fig. 1, or with both of said adjoining standing wales, as shown at d in said figure. I/Vhen it is caused to engage with but one of the adjoining standing Wales, the yarn of the sinker-Wale passes diagonally from a course in one needle-wale to an adjoining course in the adjoining needle-Wale, and when the yarn of the sinker-Wale is caused to engage both of the adjoining needle-wales it is displaced bodily into the adjoining course. W here a larger eyelet-hole is to be formed, the sinkerwale yarn in a plurality of adjoining courses may be displaced and caused to engage either one or both of the adjoining needle-wales, as

l l i shown, for instance, at e in Fig. 1.

The disposition and manipulation of the needles for effecting the operations described will be understood on reference to Fig. 2, in whch a represent cylinder-needles for producing the wales a of the fabric, and b represent needles, pins, points, or other instruments for producing elongated sinker-wales and transferring the same to one or both of the adjoining standing Wales.

In knitting plain web the cylinder-needles a alone are in action; but when it is desired to form an eyelet-hole a needle I) is projected between adjoining cylinder-needles to such an extent that the knitting-yarn is laid behind its latch, and before said needle b can reach the yarn-feed it is projected and shogged laterally to carry the loop of yarn thereon into such position that the adjoining cylinder-needle a, when projected, will enter said loop, whereupon the retraction of the needle I) willcause the casting of the loop therefrom onto the cylinder-needle, said needle 6 being then restored to its normal position preparatory to a repetition of the operation, when another eyelet-hole is to be produced.

If the enlarged sinker-Wale is to engage with both of the adjoining needle-wales, the needle I), after being projected, is first shogged in one direction for applying its loop to one cylinder-needle and then in the opposite direction for applying said loop'to the adjoining cylinder-needle, and is then retracted to cast its loop and restored to its normal position, or asplit needle of the character shown in the patent of Lee, N 0. 535,705, dated March 12, 1895, may be used for spreading the loop and applying it to both cylinderneedles at once.

IVhen it is desired to displace the yarn of a plurality of adjoining courses of a sinkerwale, the needle I) receives two or more successive feeds of yarn before being manipulated, as described, in order to transfer the loops upon it to the adjoining cylinder needle or needles.

It will be observed that knitted web in acand f, respectively,

.cordance with my invention can be readily produced upon a machine equlpped wlth ordinary latch-needles.

Heretofore, so far as I am aware, knitted webs of the character to which my invention relates have only been produced upon machines equipped with spring-beard needles, the formation of the eyelet-hole demanding transfer of a stitch from one needle-Wale to an adjoining needle-Wale, so as to interrupt the continuity of the needle-wales, and such transfers can only be effected by the use of special mechanism supplementary to the needles. In carrying out my invention the use of needles I) is not absolutely essential, as it will be evident that in very many cases a simple pin for receiving the elongated sinkerloop and transferring the same onto an adjoining needle will answer the same purpose as the needle which I have shown and described.

I claim- 1. A knitted web having eyelet-holes therein formed by laterally dis lacing the yarn of a normal sinker-Wale ac jacent to a sinker-Wale wlich is not thus displaced and causing said displaced sinkerwale to engage an adjoining needle-Wale.

2. A knitted web having eyeletholes therein produced by laterally displacing the yarn of a sinker-Wale and causin it to engage both of the adjoining needle-wa es.

3. A knitted web having eyelet holes therein produced by laterally displacing yarns in a plurality of adjoining courses of a sinkerwale, and causing said displaced yarns to en gage with an adjoining needle-Wale.

4. A knitted web having eyelet-holes therein produced by laterally displacing yarns in a plurality sinker-Wale and causing said displaced yarns to engage both of the adjoining needle-wales.

5. The mode herein described of producing a knitted web having eyelet-holes therein, said mode consisting in manipulating sinker-wales between adjoining needles of the set upon which the web is produced, by elongating a sinker-Wale in a plane different from that in which the stitches are formed, and then transferring said elongated. sinkerwale to one or both of the adjoining needles.

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