4 Claims.

' This invention relates to knitted fabrics, and more particularly to a fabric having floated and inlaid loops'combined with plain stitches so arranged that the fabric is substantially run-resisting'.

One object of the present invention is to prov'ide a knitted inlaid fabric of the' above nature having a novel sequence of stitches, floats, andL inlaid pile loops, whereby the resultant fabric may readily be napped to produce a thick woolly appearance.

A further object of this invention is to provide a knitted pile fabric of' the above nature and meansr to produce the same, which will be relatively simple in construction, easy to manufacture,` flexible-relatively nonelastic, non-crushable, substantially run-resisting, and'very durable and efficient in use.

With these and other objects in View, there have been illustrated by the accompanyingdrawings two forms in' which the invention Vmay be conveniently-embodied in practice.

In the drawings: y Figure 1 representsa diagrammatic' plan vie of a circular twelve station knitting machine for producing the improved knittedfioated and inlaid fabric of -this invention.

Figure 2 is an enlarged View of the front sur'- face of one form of knittedA pile fabric embodying the features and principles of this invention, in which three yarns are fed to the stations where the inlaying occurs.`

Figure 3 is a view similar to Figure 2 but'showing another form of knitted pile fabric embodying the features and principles of this invention, in which a single enlarged yarn is fed toi-the inlay stations.

Figure 4 is a sectional view, taken on the line 4 4 of Figure 2, looking at one course of the fabric.

Figure 5 is a sectional View, taken on the line 5 5 of Figure 2, looking at one wale of the fabric.

Figure 6 is a development view of a portion of the stationary needle actuating cylinder cam.

Figure 7 is an enlarged vertical sectional view taken through the rotating. needle' carrying -cylinder and the cam mechanism for actuating the needles and sinkers.

Figures 8, 9, and 10 are sectional views illus- .trating the three different arrangements of the long and short butt needles taken through the .lines 8 8, 9 9, and I I0, respectively of Figure 6; v

Figure 11 is an underside -view of the sinkeractuating. cam;

'I'he inlaidknitted` fabric of the presentinvention is made on an ordinary twelve feed Wildman machine in which thevarious cams and other parts of the machine have been arranged in a novel manner.

Referringnow to the drawings wherein like reference numerals designate like parts throughout the several views, the numeral Ill (Figure '7), indicates a circular stationary base, or table, upon which va plurality of upstanding brackets II are mounted. VThe brackets II serve to support a stationary ring member I2, which carries a plurality ofA segmental cam plates I3 adapted to actuate a series of sinkers I4. The snker or cam plates I3 are adapted to be adjusted radially of the ring member I2 in the usual manner by means of a thumb-screw I5 which may be turned to vary the length of the loop orv stitch measured off from the yarn.

lMounted on the base I0 are a continuously rotating needle carrying cylinder Iii, and a sta;- tionary annular needle-actuating cam I'I (see Figure 7), the latter being rigidly secured to the table I0 and located below the ring member I2. The needle carrying cylinder IS carries the usual series of alternating long and short butt needles I8 and I9 having long butts 29 and short butts 2| respectively, which'are adaptedto -be engaged successively by lower and upper cam plates 22 and 23, respectively, forming part ofthe needle cam to alternately move said needles up and down in the usual-manner. In Figure 6, the dotted line-represents the movements of the long butt needlesl I8, while thev dot and dash line indicates the movements of the short butt needles I9. Each of the needles I8 and I9 is providedat its top with the usual form of normally open spring beard 24 which is adapted to `catch the yarn `on the downward stroke of the needle, and when closed by the pressers 25, to cast off a stitch in the-usual manner.

Operating between the successive needles I8 and I9, and cooperating therewith, are the sinkers I4 which lare arranged to reciprocate horizontally underthe control of the sinker cams I3, the length of the stitches being determined by the adjustment of the thumb-screw I5.

The pressers 25 are arranged in vertical position, one opposite each needle, andsaid pressers are adapted to close the beards 24 of the needles I8 'and I9, and produce plain stitches when engagedby presser cams 26 which are located at stations A, C, D, E, G, H, I, K, and L. The presser cams are omitted at stations B, F, and J, for a purpose to be described laterll In order tolhold thebeard pressers`^25 normally awayfroxnL the 30, 3l, and 32, which cooperate with theupper and lower cam plates 22 and 23 (see Figure 6), to raise and lower the long and short buttneedles I8 and I9, according to the novel sequence of the novel fabric. The three sets of needle actuating cam members 30,"`3I,'and 321arefeacl'1A different-the set being used atcourses "Ap,

D, E, H, I, and L, to produce plain stitches at every wale, the set 3| being `used at courses B,

F, and J, to produce alternating floats and inlays 34, and the set 32 being used to produce alternating oats and plain stitchesfat# courses IC, G, and K, `The cam members 30 are`-th`e 'regular form of cams used for plain knitting; and as indicated in Figures 6` and 8, both the -long and short butt needles I8 andfIII are"alternately i raised and lowered-stitches b'e'in'g cast olf at every Wale in the usual manner. The cam members 3| differ from `thecam-members 30 by-fincluding aspecial cut-away plate: 33, which is adapted to act on thelongbuttneedle I8 ito raise it only partway, as shown in Figure 9, so that the yarns fed at this course Will'be looped over the beard 24 of said needle I8 by its cooperating sinker I4, while the short `butt needle I9 is in full raised position. i The cam members 32 differ from the sets 3D in that the short butt needles I9, as` shown in Figure 10, remain down out of actio'n" while the long butt needles I8 are up and in knitting position, thus producing alternating floats 36 and plain stitches at courses C, G, Vand K cam members 33 are provided, the omission of the presser cams 26 produces a courseV of alter- I every even numbered Wale and plain stitches at odd Wales, and a course of plain stitches.

nating pile floats 35 and loose inlays 34.

In the fabric shown infFigure 2, one yarn is fed at each of the stations A, C, D, E, G, H, I, K, and'L, while three yarns are fed at'the remaining stations B, F, and J, where the floats and inlays are produced. 4

The fabric shown in Figure 3iis identical with that of Figure 2, exceptthat instead of feeding three yarns at stations B, F, and J, asingle enlarged yarn is supplied at said stations. In both At the stations B, F, and J Where the special'.

cases, the inlaid yarns 34 will be firmly tiedinto the fabric as indicated at 3'I, i. e.,the yarn from the courses D, H, and L,-serving to hold the inlaid loops 34 formed at the courses B, F, and J, respectively. The above described sequence is repeated at each succeeding set of four feeds, or f courses, as long as the machine is operated;

As all of the floats 35, inlays 34, and floats 36 are disposed upon the same, or outer surface of the fabric, the back surface thereof Will be relatively smooth. The front surface of the fabric containing such floats and inlay loops or piles, will then be subjected to the action of a napping machine whereby the fibres of the yarn will be spread apart and raised to produce a surface having woolly characteristics. l

The layout of the 'fabric of Figure 2, which repeats every four coursesand four wales, is indicated by the following table Where P-represents a plain knitted stitch, F a float 36, I an elongated raising the lower needle to bring its beard into line with a sinker and cause more yarn to be measured off:

In short, the invention includes all the modifications and embodiments coming Within the scope` of the appended claims.
