KNITTED WEB Specification of Letters Patent.

Patented March 10, 1908.

Application filed April '5, 1907. Serial No. 866,589.

To all whom it may concern:

Be it known that I, ROBERT W. Soon, a citizen of the United States, residing in Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in Knitted Webs, of which the followingis'aspecification.

My invention relates to that class of knitted webs Whiclihave a" backing yarn com.-

bined therewith for fleecing or other purposes,

one object of my invention being to so construct such a web that the backing yarn can be confined thereto Without the use of an extra tying yarn, a further object bein to provide a well ventilated web of this 0 ass,

and a still further object being-to produce certain ornamental effects in the Web:

In the accompanying draWi n'g's Figure 1 is an exaggerated view of a piece of knitted web with backinlgl yarns secured thereto in accordance wit my invention, Fig. 2 is a similar view illustrating another embodiment of m invention, Figs. '3 and 4 are views'on a sti more exaggerated'scale illustratin the manher in which my invention may. e carried into effect, and Figs. 5 and6 are views of certain instrumentalities employed incarryout the invention. I

n the'fabrics shown in- Figs. 1 and '2 a represents the needle wales and b the'sinker' wales, extending from one needle wale' to they next, and 12 represents the-backing yarn which will usually be. of heavier material than the yarn of whichthe webis composed.

In order to secure this backing yarn to the web 100 s in certain wales of the'latter are dis lace and engaged with the adjoining wa es, and the backing yarn l one face of the web is inter aced'with the latter by passing it to the opposite face of'the;

dis laced loops. a

the web shown in Fig. 1 the displaced 100 s J are those of the-sinker wales, andsuc I isplacement may be effected in any of the ways set forth in my Letters Patent N 0-. 846,353 dated March 5th, 1907, that is to sa the displacedloops may be. loops of a sing 6 course, or; of a number ofsuccessive courses, and they may be displaced into' a needle Wale on one side of the sinker wale orinto needlewales on each side 'of the same. In the present Instance I have shown,'1n course I i, sinker wale loops of a single course, and, in I courses'm and n, sinker wale loops of two sucg loosely on ces'sive' courses. transferred to an adjoining needle wale. The result ma also be attained by deflecting needle wa es into an ad-- joining Wale or distending them so as to engage with'wales oneach side of the same,

and in F 2'is represented a web in which the firsto these methods has been adopted, as at g' the'backing yarn, in each of the webs shown,

assing .to t 6 other face of the, transferred oops. Either .a single backing yarn or a plurality of the same may be introduced at each transfer, both of these plans being illustrated in Fig. 1, and said 'backingyarn is preferably formed into loops between its successive oints of attachment to the web as shown 0th in Figs. 1 .and'2, in order, firstlyfthat-it .may not detract fromthe on onerface of the web and elast1cityof the web,. and secondly, that it may be more conveniently and effectively brushed'or'gigged to form a fleece, if such a fleeced backing'is desired. The transfer of sinker waleor'needle Wale loops in the man- 'ner described results in the formation of eyelet holes inthe knitted web where such transfers take place, and this not only increases the atttactiveness of such Web, but alsoimproves the same from a hygienic viewpoint,

with the knitted web in themannerv shown in Fig. 1 will beunderstood in reference to Fig. 3 in which 0: represents the needles for producing the face web and w represent transfer points for producing an elongated sinker wale' andtransferrin'g the same to an adjoining needle Wale, each of said transfer points consisting of a'stem 1 having an outer end '2. and a dlagonally inclined ortion 3 with shoulder! at its inner end. he transfer point is first projected until its outer end 2 occupies a POSltiOIl between two of the cylinder needles as shown at w in Fig. 3, such projection occurring either before or after the projection of-the needles to receive the yarn from the yarn guide.

gem at each e elet hole- When 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 oint, and the latter may retain its position or one or more courses of the knitting, de-

ending upon the number of sinker Wale oops to be included in the-transfer. The transfer point is then projected so as to bring its inclined member 3 into action upon the loop or loops hanging upon the end 2 as shown at w in Fig. 3, thereby causing a lateral displacement of such loop or 100 s, as well as a slight outward displacement ue to the action of the shoulder 4. This brings the loop or loops into the plane of the adjoining needle 00 and all that is necessary to complete the transfer is to project saidneedle into the loop or loops an then retract the transfer point as shown at 'w in Fig. 3, so as to cast said loop or loops onto the needle. Before the needle is thus projected however, a backing yarn guide 2 lays the backing yarn d behind the needles a: and under the transfer point, this operation preferably taking place before the transfer point has been projected so as to deflect the loop or loops hangingupon it. As a consequence of this operation the said backing yarn will be laid behind the stitches upon the needles and in front of-the loop or loops upon the transfer oint and hence will be bound into or inter aced with the fabric when the needle engages said loop or loops, and then draws a stitch through the same.

In producing a fabric of the character shown in Fig. 2 the transfer point acts upon a needle Wale, as shown in Fig. 4, so as to distend the stitch upon one needle until the adjoining needle can enter the same, the stitch being then cast from the transfer point onto said receiving needle. In this case the needles from'which the stitches are to be transferred should be provided with offsets, shoulders, or the like, whereby an abnormal rojection of the needle will so locate the stitch upon it that they outer end of the transfer point can readily enter the same, as shown for instance at w, in Fig. '4. One form of needle available for the purpose is that,

shown in Fig. 6, said needle having an outwardly extending 1001p1 '0 for the entrance of the transfer point, w 'ehengages the stitch hanging upon the upper member of said loop. In this case, the needle should be withdrawn after the loop has been engaged by the transfer point, in order to permit ofthe laying of the backing yarn behind the needles and be low the transfer point, as shown at wiin Fig. 4, slight shogging movement of either needle or point being effected in order to prevent engagement of the outer end of the point with the loop o of the needle when the atter is retracte or the needle or point springing laterally out of the way, as a result of such contact. A needle having a stem at an angle to its shank, such as shown in my Letters Patent No. 837,763 dated Oct. 30, 1906, may be used, and in such case the transfer of the stitch may be effected by a shogging of the needle itself, and without the use of a special transfer point, the needle being first raised high enough to permit of the introduction of the backing yarn behind the standing wale stitches and in front of the stitch which is to be transferred. The looping of the backing yarn may be effected by sinkers or loopers disposed in any desired relation to the transfer point, one arrangement f such loopers being shown at s in Fig. 3.

I am aware hat rior to my invention filling strands of rubber have been combined with knitted webs, by laying them between. needle Wale stitches and transferred sinker wale loops, but such transfer have been effected in every sinker Wale and every course. The introduced strands therefore were not exposed on either face of the fabric, and were not susceptible of forming a fleeced back thereon, nor did the transferred 1003s form, in the face web, eyelet holes of the character which I have shown and described, there being no plain courses in the sinker wales between the courses in which the transfers were effected and no needle wales between the sinker wales in which the transfers were made.

One of the advantages of my invention is the facility which it affords for the production of webs having a back composed of linen yarn which material is preferred in many cases where the web is to be used for the making of undergarments.

Owing to the relatively harsh and unyielding character of such linen yarn, it does not lend itself readily to the formation of a knitted web u 'on an ordinary knitting inachine, especia y when the latter is of fine gage.

A knitted web such as that constituting my invention can, however, be composed of cotton or other soft yarn with a backing yarn of linen, which, owing to the fact that it does not have to be drawn into stitches by the needles of the machine, can be as heavy as may be desired.

I claim:

1. A knitted web having a backing yarn exposed across one or more needle wales on oneface of the web, and secured to said web by loops transferred from one Wale to another.

2. A knitted web having a backing yarn exposed in the form of loops on one face of the same, and secured to said web by loops transferred from one Wale to another.

3. A knitted web having eyelet holes therein and a backing yarn exposed on the back of the web, and crossing said eyelet holes, whereby, at such eyelet holes itis also I therein, and having groups ofbacking yarns exposed on the other face of the web. 4. fA knitted web having a backing yarn exposed across one'or more needle wale's on one face of the web, and secured'tosaid web by loops transferred from one-wale to another and forming eyelet holes in saidweb.

5. A knitted web having a backing yarn secured thereto by engagement with'sinker wale loops transferred to an adjoining needle wale or wales, said backing yarn be ingex posed on the back of the web.

6. .A knitted web having eyelet holes formed therein by transfer of sinker wale loo s to an adjoining needle'wale or wales, an having a backing yarn secured thereto by engagement with said transferred loops, said backing yarn being exposed on the back of the web. I

7. A knitted webhaving eyelet holes formed therein by transfer of sinker wale loops of a plurality of successive courses to an adjoining needle wale or wales, and having' a backing yarn secured thereto by engagement with said. transferred loops, said backing yarn being exposed-on the back of the web. i

8, A knitted web having eyelet holes crossing said eyelet holes.

9. A knitted web having eyelet holes formed therein by transferring sinker wale loops of a succession of courses to an adjoining needle wale or wales, and a plurality of loops. 1

10. A knitted web. having eyelet holes separated from each other by one or more normal courses, and a backingyarn lying bebacking yarns engaged with said transferred hind'the web, but crossing said eyelet holes 40 and thereby exposed on the opposite face of th'e-web. i i

.11. A knitted .web' having eyelet holes separated from each other by one or more normal courses and one or more needle wales,

and a backing yarn lying behind said needle wales, but crossing the eyelet holes and thereby exposed on the face of the web.
