' J1 claim. (c1. ses-169) My invention relates to a knitted fabric and a method of making the same, the principal object of the invention being to provide a run-resisting plain knitted fabric. The terni plain ,5 knitted fabric is used in this specification to distinguish on the one hand from v`warp fabrics which have a plurality of yarns running substantially lengthwise of the cloth and shogged laterrally so as to be interknit with other Warp yarns,
10 and on the other hand to distinguish from rib fabric or other special fabrics, the term indicating substantially such fabrics as are made by a single sexies of needles each formingloops successively from a yarn or yarns fed continuously tol a series courses running crosswise of a flat knitted fabric or round and round in the case of a tubular fabric.
When a stitch is broken in a plain knitted fabric the continuity of a NWale is interrupted and usually the successive concatenated loops slip successively out of one another, so making what is 1 i also taken by the needles at every Wale, it,being Yknownas a run or ladder. Such plain knitted fabrics arelsometimes provided with anti-run courses to stop runs. Warp fabrics are usually substantially or entirely free from runs and ribbed fabrics run in one direction .only but plain knitted fabrics run either up or down the Wale and commonly run very freely, particularly when madefrom slippery yarns such as silk or rayon yarns. The fabric of my invention is distinguished from 'other plain knitted fabri/cs by the fact that it does not run even under very rough treatment after a break in a Wale or Wales.
ance of the garment. My method of knitting provides for the lrsttime,so` far as known tc me, plain knitted fabrics Lthat canbe vmade on an vvrdinary plain knitting machine and which are runproof in every part of the fabric or tlie garment made therefrom. f
A further object of the invention is 'to provide a run-resisting fabric of the character described which shall be'light in Weight and thus suitable for use .in the manufacture of light-weight um,
derwear, pajamas, dress goods, etc.
Referring to the drawings. which are made i reference characters indicate similar parts:
Fig. 1 is'a plan on a greatlyenlarged scale showing one sidev ofthe fabric,
Fig. 2, a similar view showing the o of jneedles' in succession so as to be knitted into a part of this application andin which similar piosite'side,A

f Fig. 4, a vertical /section through a portion of a .circular independent needle machine on which the fabric has been made, and. 5
p Figs. 5 and 6, sections respectively onlines 5-5 and 6 6 of Fig. 3,` illustrating the positionof the needles with respect to certain needle cams.
Referring first to Figs. 1 and 2 Which illustrate the fabric structure made on a multiple-feed cir- 10 cular machine having independent spring needles, reference character I0 indicates a yarn whichy is taken by 'certain needles in each Wale of a course, i. e., it is formed into a loop at each needle, whichloop is interknitted With prior and succeeding stitches of the corresponding Wale so as to form a knitted stitch in each-wale of the fabric. The
yarnll of the second feed is knitted into the second', fourth and sixth wales, i. e., in alternate wales, but oats across the rst, third, iifth and seventh wales. The yarn' I2 ofthe third feed is similarn in this respect to yarn l0. The yarn l3 of the 'fourth feed is knitted-in Wales intermediate the alternate Wales where yarn Il is knitted For convenience the second, fourth and sixth 30 y Wales are hereinafter designated as alternate Wales vand the first, third, fifth and seventh Wales are designated as intervening wales. It will. be noted that the feeds in this linstance are shown asarranged in sets of four though I do not necessarily limit myself to such arrangement. Inin- ,terveni'ng wales the yarn I0 forms long stitches While in alternate wales it is drawn into short tight stitches; all stitches of yarns II and I3 are long; yarn I2 has long stitches in alternate wales 40 and short ytight stitches in intervening'v wales, or in opposite order as compared with yarn Ill.v It will be-seen that in each Wale two long stitches (-relatively speaking, for in the actual fine fabric all stitches are small and short, being made of ne 'yarn and forming a close fabric), are followed by a tighter stitch that embraces the neck of a long stitch and chokes it so as to stop a run at once. Each Wale has the same' number of stitches in, a given length, as the floats of yarns Il and |3150 occur in dierent wales-and are evenly divided. The floats conceal the body of thefabric to a considerable extent and4 this feature, together With the multiple feeds, etc., affords extensive possibilities in the Way of variations in appearance of the fabric, which can obviously be further varied by the use of yarns of diiferent color or quality at the various feeds. Y
In the preferred form of the fabric here shown the yarn I0, or at least /a yarn similarly knitted into each Wale, follows the yarn I3 in the next course and is followed successively by yarns Il, I2 and I3 in ensuing courses and so on, but it will be understood that I do not necessarily limit myself to the precise number and arrangement of yarns illustrated in the drawings.
I have shown in the.drawings portions of a multiple-feed circular independent spring needle knitting machine, thisV machine comprising a rotary needle cylinder I4 on ra frame l5 which also supports a xed cam carrier I6 carrying the needle cams for reciprocating needles |1 to knit a fabric, it being immaterial, however, Whether the needle cylinder or the cam carrier rotates. The needles are arranged in two sets, one set having long butts I8 and the other set having short butts I9 as shown in Figs. 5 and 6, the series consisting of short butt and long butt needles occurring alternately. At such a feed as indicated at the middle of Fig. 3 there is a needle raising cam 20 for elevating all the needles, in
the manner indicated by the two broken lines,
the dotted line indicating the course of travel of the butts of the short butt needles and the dash line indicating the course of travel of the butts of the long butt needles. Cam 20 is followed by a stitch cam 2| and it will be seen from the drawings that allthe needles are raised at this .feed to take the yarn (e. g. yarn IU) and all the needles are lowered to draw loops, hence the yarn supplied at this feed forms loops at each Wale. The relative direction of travel of the needles with respect to the cams is indicated by the arrow in Fig. 3 and after passing stitch cam 2| the long butt needles only are elevated by cam 22, the butts of the short butt needles passing along the top of a ledge indicated at 23 and not being elevated sufliciently to take the yarn, but holding their old loops. The long butt needles which are elevated by cam 22 take a new yarn at this feed, e. g. yarn II of Figs. 1 and 2, and are then drawn down by a stitch cam 24 to draw loops of yarn I I in alternate Wales. Stitch cam 24 is suiiliciently lower than 'cam 2| to draw' somewhat longer stitches in each alternate Wale than lthose in the preceding course, and the stitches'o'f yarn Ill in intervening wales, being held by their needles,
rob the stitches of said yarn in alternate Wales so as to make the last-named stitches `very short and tight, whereby they hug the necks of the stitches of yarn |I closely so as to arrest any incipient run in the corresponding wales. The short butt needles which are holding loops of Vyarn IU drawn in the previous course also movev l cam like cam 2| to draw loops of yarn l2 on all tight stitch for arresting a run in such Wale.
-of yarn I3 and knit off the old loops of yarn I2.
The stitch cam 21, similarly to stitch cam 24, extends down to a lower level than does stitch cam 2| and the loops of yarn |2 in intervening wales are robbed in the manner above described, so l5 that in the final product yarn I2 has long loops in alternate Wales and short run-preventing loops in intervening wales.
In a fabric formed as above described, each Wale has stitches at brief intervals which ef- 20 fectively bind down the intermediate long loops to prevent them from running. At the same time the floats of yarns and I3 on one face ofthe fabric conceal the body of knitted yarns quite thoroughly and so form a characteristic effect, 25 which can be taken advantage of also for color `effects by the use of yarns of different colors,
or by using stronger yarns as binders With more expensive and ornamental yarns in the courses having floats, thus securing a sort of plated ef- 30;l
fect.
In addition to the parts above described the cam ring of the machine is provided at appropriate points with guard cams 28 and the machine has a sinker bed l28' for sinkers 29, which 35 sinker bed also forms part of the supporting means for pressers 30. Posts 3| on the support for the cam ring carry sinker cams 32 and means for actuating the pressers, all as known to those skilled in the art. 40.
types than that illustrated and that changes may 45,
be made in the machine and the` fabric all without departing from the spirit of my invention; therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claim.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patentis:
A run-resisting plain-knittedfabric having repeats comprising a yarn knitted with short tight 55 stitches in alternate wales and long stitches in intermediate wales, a second yarn knitted with long stitches in alternate wales and floated over intermediate Wales, a third yarn knitted with long stitches in alternate wales and short tight stitches in intermediate Wales, and a fourth yarn floated over alternate Wales and knitted into long stitches in intermediate wales, whereby in each Wale two long stitches are followed by a short DAVID SIEGEL.
