invented certain` Improvements `in Ribbed Knitted Webs, of which the following speciticetion.. u i

The object of my invention fis to provide e ribbed fabric of uniform character and pos-I sessin the quelity'of elasticity eharncterlstic of a ri bed fabric but havlug a closerdisposition of the waies and a heavier or hrm'crv `texture than eA ribbed knitted fabric produced in the usual way, my invention alsd providingy a ready means for producing ver tical stripes or other ornamental etlects in the web. l

In producing e liebric of the'cheructergdescribed en ordinary rib knitting machine n 1e 5o be employed but the ncedlesol'l both the cy inde-r and dial of said machine are disposed in independently lop'creijile sets, s needle of one set alternating with :t needle of the other set both around the'cylinder and around the dial, thus, as shownin Figy, the cylinder Specification of Letters atent.

needles 1' which produce the'face wales 1 of one web alternate with the cylinder needles 3 which produce the face wales 3 ofthe other web, and in like manner the dial needles 2 which produce the lmck'wales 2 of one web alternate with diztl needles 4 which produce the back /wnles 4, of 'the other web, the dial 4needles 2 being in line with the cylinder needles-3 und the die] needles 4 being in `line with the cylinder needles 1,

In order that they may beindependently operated the needles of one set may be longer then the needles of the other set, or` may have their projectin r'butts in different plaines so as to be opereb e by diflerent sets of rams, and the machine will be e uipped with one or more yarn guides for eac i set of needles, one guide feeding its yarn to the 'nrwdles la and 2 in the production'of one -eourse 'of the web und the next guide feeding its yarn to the needles 3 and 4f* in -the production ot' the next course et' the web, where'- by, while'the two webs ere, in effect, independent of 'eachother and inde endently produced, they are so interlocked y means of their crossing sinker wales as to constitute, in eil'ect, one fabric.

The value of my invention in the production of ribbed fabrics of close or heavy'teX- ture will beunderstood when it is borne in mind that it is impracticable on an ordinary rib knitting machine, to produce a web hav` ing more tha-n about fourteen wales to t-he inch, on each fece, for in such ordinary rib knitting machine the dial needles alternate with the cylinder needles und consequently the-whole twenty-eight needles must be crowded into one inch of space.. In e machine for producing my improved web, however, the dini needles are in line with the cyl-v inder needles, hence the only limit to thev number ol' wales in the web is the" limit of iineness to which euch needle-carrying member of the mur-.hinecun be cut, and I can produce ribbed webs having as many estwent four wales to thc inch on each fece, while t ie knitting opere-t ion een be :nrricd on with the seme facility es in unordi-nztry rib knitting machine having n gage of but twelve t0 the inch, in euch noodle cnr-rior, owing to the fact that but one hall' of the total number 0f needles ero'knitting at euch feed. I can therefore produce ribbed fabric having a much iiner texture than usual, arising from the closer disposition ot' the Wales and l can prodrawing, each of the ribbed webs composingA the same constitutes a one-and-one ri with' needle wales of one face alternating with needle wales of the other face, the ribs of either ,I

or both faces of 'either or both webs may conf l sist of a plurality of wales, if desired, de-

pending upon the dis )osition and mode of operation of the needles of the two sets in each of the needle carriers, and the character of the stitches inthe webs may be varied b tucking upon the needles of either or bot of the needle carriers in the customary man- It may, in some cases, be necessary to produce a welt on my improved fabric, such welt consisting of a `series of plain courses of stitches, such for instance, as shown at 6 in Fig. 3, these stitches being produced while the formation of theribbed webs is tempoi rarily suspended. In order to produce such a-welt, the Canis for operating both sets of rendered inopdial needles are tempoiaril erative while both sets pf cylinder needles are caused to knit4 at the same yarn feed, a special cam beingv employed in the cylinder for actuating that set of the cylinder needles.;

which, in the normal operationof the mai chine, is not caused to engage the yarn at that feed.

By providing the yarn feed for the needles of one set with yarn of a differentcolor from vertical stripes can be produccdin the sinieacli yarn feed Awith any of the usual means connection' with such a web. I aiu also aware that it has been proposed to combine a ribbed web with a plain web havin its needle wales disposed between the nee e wales ol' one face of said ribbed web, but such a composite fabric is of uneven character owing to the fact that single wales alternate with double wales throughout the fabric and its elasticity is reduced to that ofthe )lain web which limits the stretching of the rilbbed web and therefore deprives the composite fabric of one of the principal characteristics of a ribbed web.

I claim: 1

1. A knitted fabric comprising two ribbed webs with crossiiiggsinker wales, each face of the fabric presenting first a ribA of one web and then a rib of the other web.

2. A knitted fabric comprising two ribbed webs withcrossed sinker wales, the ribs of one web being dis osed in the spaces between the ribs of the ot er web.

3. A knitted fabric com )rising two interlocked ribbed webs, with crossed sinkei wales and a welt composed of a plurality of successive plain courses.

4. The mode herein described of producing a knitted fabric, said mode consisting in feeding one yarn to one set of needles drawing stitches first in one direction and then in the and feedin another yarn to-an alternating.
