RIBBED KNITTED WEB.

To all whom it may concern:

Be it known that I, ROBERT W. SCOTT, a citizen of the United States, residing in Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in Ribbed Knitted 1Webs, of which the following is a specification.

The object of my invention is to produce ornamental effects in ribbed knitted fabrics by special manipulation of the stitches of said fabrics.

In the accompanying drawings-Figure 1 is an exaggerated view of a piece of ribbed knitted web in accordance with my invention, Fig. 2 is a diagram illustrating the arrangement and operation of certain instrumentalities whereby the same can be produced, and Figs. 3 and 4 are views illustrating certain of said instrumentalities.

Referring in the first instance to Fig. l of the drawing c represent the wales of one face of the web which may, for instance, be those produced upon the cylinder needles of the rib knitting machine, and b are the wales of the other face which may be those produced upon the dial needles of the machine, the web shown constituting what is termed a three-and-three rib, that is to say, it has cylinder needle wales in groups of three alten nating with dial needle wales in groups of three. In the present instance the ribs produced by the needles o are normal but those produced by the needle wales c have eyelet holes formed in them by transferring a stitch from the central needle wale of the rib to a wale on one side of the same, as shown at c, and then drawing a new loop d upon the needle from which the stitch has thus been transferred.

In order to better distinguish the ribs from one another I have, in the drawing, shown the stitches constituting the ribs of one face in heavier lines than those constituting the ribs of the other face.

It will be observed on reference to Fig. l that the outer needle wales c recede from each other at the point where the eyelet hole is formed, consequently the rib of which these wales form part is alternately distended and contracted, the normal ribs formed by the needle wales being of uniform width but pursuing a waved or undulating course corresponding to the expansion and contraction ol' the ribs of the other face, the expanded Specification of Letters Patent.

Application filed April 1, 1907, Serial No. 365,740.

Renewed July 6, 1909. Serial No. 506,214.

-instrumentalities for producing eyelet holes in the ribs in the manner described will be understood on reference to Fig. 2, in which a: represent cylinder needles for producing the wales c of the web, y represent dial needles for producing the wales b, and w represents a transfer point for conveying a stitch from one -v wale of a rib to another wale of the same.

The transfer point w has a stem l, an outer end 2 in line therewith, a diagonally inclined or stitch-deiiecting portion 3 with shoulder 4 at the base of the same, a short sub-stem 5 parallel with the main stem and a transverse neck 6 connecting said sub-stem to the main stem (see Fig. 3). The needle from which the stitch is to be transferred should be provided with a shoulder or offset, which, when the needle is projected to an abnormal elevation, will engage and stretch the stitch last formed upon said needle, in order to permit of the entry of the outer end ofthe transfer point w into said stitch, the stem 1 of the transfer point being radially guided in the needle dial or other convenient support in a plane co-incident with the vertical plane of movement of the needle. In the present instance the needle has an outwardly projecting loop 'u whose upper member, when the needle is abnormally projected, engages the stitch and moves the same into proper position for the entrance of the outer end of the transfer point. Continued movement of said transfer point then brings the stitch under the influence of the diagonally inclined member 3 of the point, with the result that the yarn constituting one side of the stitch is deflected laterally to such an extent as to overlie the plane of movement of the next adjoining cylinder needle a, as shown in Fig. 2, said needle being then projected into position to engage the deflected portion of the stitch, whereupon the transfer point is retracted, the transfer operation being completed by withdrawing the needle upon which the stitch was originally formed so as to cast off said stitch, the needle, however, being immediately restored to action, in order to Patented Aug. 24, 1909.

Y ,aries of the eyelet hole.

If it is desired to form eyelet holes in the ribs of both faces of the Web the cylinder may be provided With transfer points of the character described for action upon the dial needle stitches in a manner similar to that set forth in connection with the cylinder needle stitches.

When it is not considered important to mount the stem of the transfer oint midway between the groups of needles o that member of the machine which carries said transfer point, said stem need not be in the plane of the outer end of the point, and thel transverse neck 6 can then be dispensed with, and, if desired, the transferred stitch may be distended in both directions so as to engage With the Wale on each side of the same by the use of duplex transfer hooks, such as are shown and described in my Letters Patent No. 846,430 dated March 5, 1907.

The purpose of permitting the needle from which the stitch is to be transferred to retain its hold upon said stitch until the receiving needle has entered it, is to cause the spreading of the stitch by the discharging needle and thereby provide, for the entrance of the receiving needle, an opening of larger area than would be presented if the stitch was cast from the discharging needle before said receiving needle had entered it, for, in the latter case, the transfer point Would deflect the stitch directly from the upper edge of the knitted Web and would thus tend to contract said stitch and render it more difficult for the receiving needle to ass through the same. When such distentlon of the stitch is not desired, however, the needle from which the stitch is to be transferred may be constructed as shown in my Letters Patent No. 834,763, dated October 30, 1906, With a stem at an angle to its shank and the stitch to be transferred can be deflected laterally to the desired extent by a lateral shogging of the needle after the same has been raised so as to be free from the control of the cylinder, or, even in the latter case, distention of the stitch may be effected bycausing a straight point to be projected into engagement With the stitch before the shogging movement of the needle is effected, or the shogging movement may be imparted to such stitch-engaging point instead of to the needle.

I prefer to carry out my invention in connection with that class of ribbed webs Which have three, or some other uneven number of Wales in each of the ribs in Which the eyelet holes are to be formed, and to transfer the stitches from the intermediate Wale of the group in order to locate the eyelet holes in the center of the rib, but my invention is applicable to any ribbed Web having a plurality of Wales in a rib, and the ribs in which no eyelet holes are to be formed may have but a single Wale if desired.

The production of eyelety holes in certain courses of a ribbed Web has the effect of expanding the Web to some extent at such courses, and this reduces, to a corresponding degree, the elasticity of such portions of the Web. In order to lessen this expansion Without correspondingly lessening the number of eyelet holes formed in the Web, I prefer to form the eyelet 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 hole of the second roW is formed in the Wale marked fm.

Independently of the ornamental effects due to the distention and contraction and to the Waving of the ribs of the web, eyelet holes, when formed in ribs constituting the outer face of the garment, serve their intended purpose better than eyelet holes formed in a plain Web, or between the 'ribs of the two faces of a ribbed Web, because the needle Wales between which such eyelet holes are formed are supported free from contact With the skin of the wearer of the garment.

I claimzf 1. A ribbed knitted Web, having, in ribs of either face, a plurality of needle Wales and eyelet holes formed by transferring stitches from one of said Wales to another Wale or Wales of the set.

2. A knitted web, having, in ribs of either face, an odd number of needle Wales, and eyelet holes formed by transferring stitches vof the intermediate Wale of the setto a Wale on either side of the same.

3. A knitted Web having normal ribs on one face, and, on the other face, ribs containing a plurality of needle Wales With eyelet holes formed by transferring stitches from one of said Wales to another Wale or Wales of the set.

4. A knitted Web having normal ribs on one face, and, on the other face, ribs containing an odd number of needle Wales With eyelet holes formed by transferring stitches of the intermediate Wale of the rib to a Wale on either side of the same.

5. A ribbed knitted Web, having, in ribs of either face, a plurality of needle Wales'and eyelet holes formed by transferring stitches from one of said Wales to another Wale or Wales of the set, the eyelet holes of one rib registering With the spaces between the eyelet holes of the adjoining ribs.

6. A knitted Web, having, on one face, normal ribs which follow a waved or undulating course, and, on the other face, ribs, each containing a plurality of needle Wales, the latter ribs having eyelet holes formed by transferring stitches from one Wale of the rib to another Wale or wales of the same, the eyelet holes of one rib registeringl with the spaces between the eyelet holes of the adjoining 1 ribs.

7. A knitted web7 having, on one face, normal ribs which follow a waved or undulating course7 and, on the other face, ribs, eneh containing an odd number' of needle i either side of the same, the eyelet holes of one rib registering with the spaces between the eyelet holes of the adjoining ribs.

In testimony whereof, I have signed my 15 name to this speeiiieation, in the presence of two subscribing witnesses.
