RIBIBED KNITTED FABRIC.

Speccaton of Letters Patent.

y Patented Aug. 12,1913.

Application filed January 20,1911. Serial No. 693,715.

To all 'whom t may concern Be it known that I, ROBERT IV. SCOTT, a citizen of the United States, residing in Leeds Point, Atlantic count-y, New Jersey, have invented certain Improvements in Ribbed Knited Fabrics, of which the follow ing is a specification.

The obj ect of my invention is to so knit an interlocked ribbed web of the character shown in my Letters Patent No. 899,439, dated September 22, 1908, as to facilitate the application of the st-itches of the same to the needles of a machine for knitting a plain or single web continuation of said interlocked ribbed web.

This object I attain in the manner herein after set forth, reference being had to the accompanying drawing, in which- Figure l is a face view, on an exaggerated scale, of a piece of interlocked ribbed web constructed in accordance with my present invention; Fig. 2 is a transverse section of the same on the line m-m, Fig. l, and Figs. 3 to 7, inclusive, are diagrams illustrating the successive steps in the operation of the machine for the production of my improved web.

An interlocked ribbed web knitted in accordance with my Letters Patent No. 899,439, consists of two interlocked ribbed members with the sinker wales crossing each other. In such a web the wales of the two members of the web are in line with one another but the courses are not, consequently it is difficult to apply stitches of courses of both we bs to the needles of a plain web machine. Even if stitches of both members of the interlocked web are lengthened or slackened, the fact that the courses of stitches are not in registry interferes with the application of the slackened stitches of overlying needle wales of the web to the needles of the machine upon which the plain web is to be subsequently knitted. I find, however, that by forming a tuck course in those wales of the interlocked web in which the courses are in the lead and thus practically losing a course in these wales, the lead is taken by the courses of stitches of the other wales, with the result that in such wales the stitches corresponding with those of the other wales preceding the tuck stitches are drawn into alinement or registry with such preceding stitches, the lead being now taken by the courses of stitches in the wales other than those which previously held it.

By preference the course of stitches preceding the tuck course and the corresponding course of stitches in the other wales are slackened or elongated, as shown in Figs. 1 and 2. 1 represents the wales in which the courses were originally in the lead, and in which the tuck stitches 2 are formed after the formation of the elongated or slackened stitches 3, the wales of the other member of the web being shown at 4, their slackened stitches at 5, and the eXtra course of stitches, which serves to place these wales in the lead, at 6.

In knitting ordinary single ribbed web the tucking of the yarn in a single course upon all of the needles would simply result in the disposal of the yarn loosely between the needle wales of the opposite faces of the web, since there would be nothing to engage and hold the yarn of the tuck course. In knitting interlocked ribbed web, however, the tuck stitches of one member of the web are engaged and held by the crossing sinker wales of the other member of the web, as shown for instance at 7, in Fig. 1.

Referring now to Figs. 3 to 7, inclusive, A and B represent the needles of one member of the knitting machine, say the cylinder, and a and 5 represent the needles of the other member or dial of such machine. In Fig. 3 m represents yarn fed to the needles A a to form the stitches 1 of one member of the web and y represents the yarn fed to the needles B b to form the stitches 2 of the other member of the web. When the slack y courses are to be formed the desired extra draft is imparted to the needles A a to form the slack stitches 3 of one member of the web, as shown in Fig. 4, and to the needles B b to form the slack stitches 5 of the other member of the web, as shown in Fig. 5, after which the yarn m is tucked upon the needles A a, as shown in Fig. 6, the needles having previously been restored to their position of normal draft. Knitting of the normal interlocked ribbed web is then resumed, as shown in Fig. 7.

My invention can be used in connection with interlocked ribbed webs of any type, and in addition to that shown in my former patent I may refer to that shown in the patent of B. F. Steber, No. 951,033, dated March l, 1910.

I Claim:

l. An interloeked ribbed Web having, in those Wales in Which the stitches are in the lead, tuck Courses whereby in the knitting of the web the lead is shifted to the Wales of the other members of the Web and the stitches of the overlying Wales are drawn into registry.

2. A11 interlooked ribbed web having, in

Wales oi each member, a slack Course, the stitches of the slack course in those Wales in which the stitches are in the lead being fol- 15 lowed by a tuck course.

In testimony whereof, I have signed my name to this Specification, in the presence of tWo subscribing Witnesses.

ROBERT W. SCOTT.
