4 Claims. (Cl. 86-191) This invention relates to knitted fabrics, and more particularly toan inlaid knitted fabric wherein the threads or yarns constituting the same are so arranged that the fabric is substantially run-resisting and includes plain stitches, oats and loose laid-in yarns.

One object oi' this invention is to provide an inlaid knitted fabric of the above nature having a novel sequence of stitches, floats and loose laid-in yarns.

A further object is to provide a knitted fabric of the above nature which will be simple and easy to manufacture, flexible and elastic, non-crushable, substantially run-resisting, and very eiiicient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawings one form in which the invention may bel conveniently embodied in practice.

In the drawings:

Fig. l represents a diagrammatic plan view of a circular twelve-feed hitting machine for producing the improved fabric.

Fig. 2 is an enlarged open view of the rear surface of an improved inlaid knitted fabric embodying the invention.

Fig. 3 is a similar view oi the reverse surface of the fabric.

Fig. 4 is a development view of a portion ci the needle-actuating cylinder cam.

Fig. 5 is an enlarged vertical sectional view of a portion of the knitting machine.

Fig. 6 is a sectional view of a portion of the needle-actuating cam, taken on the line 6--6 of Fig. 4, and

Fig. 7 is a sectional view of another portion of the needle-actuating cam, taken on the line 1-1 of Fig. 4.

One important advantage obtained by the present invention is that the improved inlaid knitted fabric may be made on an ordinary plain knitting machine without employing complicated mechanisms or special attachments, it merely being necessary to omit the use of the usual needle 45 beard-closing or presser cams wherever laid-inthreads or yarns are desired, and to arrange the needle-actuating cams to produce oats at any desired points.

Referring now to the drawings, wherein like 50 reference numerals denote corresponding parts throughout the several views, the numeral I (Fig. indicates a circular stationary base or table upon which a plurality of upstanding angle brackets II are mounted. The brackets II sup- 56 port a stationary ring member I2, which carries a plurality of horizontal arcuate plates i3 form-- ing a segmental substantially circular sinkeroperating cam member.

Provision is also made of a needle-carrying cylinder Il which is adapted to rotate'within a stationary annular needle-actuating cam cylinder i5, the latter being rigidly secured to the stationary table I0 in the usual manner and located below the level of the stationary ring member I2. The rotary needle cylinder I4 carries a plurality of long butt needles I6 and short butt needles il which are arranged alternately around the circumference of the needle cylinder It. The needles I6 and Il are adapted to be successively engaged by the grooves of the cam cylinder I5 (see Figs. 4-7) to cause said needles to travel upwardly and downwardly during the operation of the machine. Each of the needles I8 and Il is provided at its upper end with a spring beard I8 which, when in the open position shown in Fig. 5, is adapted to catch the yarn or thread on its downward stroke.

Operating between the successive needles I6 and I 'I are a series of horizontal reciprocating. sinkers I9, which are provided on their upper edges with substantially rectangular projections 20 adapted to travel within. a horizontal cam groove 2l formed in the sinker-operating arcuate cam plates i3. The cam groove 2i serves to control the outward and inward movement of the sinkers I9 at the proper times.

Provision is also made of a series of vertical pressers 22 which are adapted to close the spring beards I8 of the needles I6 and II when engaged by the presser cams 25, herein shown as located at every alternate one of the twelve feeding points.

In order to hold the pressers 22 away from the pressers 22 against the spring beards I8 of thef needles I 6 and I1 as they pass by so that the yarn will be knitted oif the needles to form loops or stitches. It will be understood, however, that where the presser cams 25 are omitted or released, the thread or yarn will not be knitted oil. but will be carried in the needle beards until the next station where the yarn will be knitted oif and inlaid with the thread or yarn of this course.

Por producing the improved fabric of this invention, the machine is provided with twelve yam- feeding stations 24, 21, 2l, 29, 24, 2|, l2, 32, 34, I5, 3Q and 31, to each of which different threads or yarns are fed through guides Il and II. As most clearly. shown in Fig. 4, the cam cylinder is provided with a set of needle-actuating cams 4I, 4i and 42 to control the' up and down motion of the alternating long butt and short butt needles I6 and l1, respectively. Three different arrangements are employed, as indicated in Fig. 4, wherein the dotted line 43 represents the movements of the short butt needles l1, and the dot-and-dash line 44 represents the movements of the long butt needles Il. At the cam 40, only the short butt needles I1 will be held up; at the cam 4I, both short and long butt needles will be up; while at the cam 42, only the long butt needles Il will be up.

At the three feeds A", "C" and E, only the short butt needles I1 will be up, causing floats 44 to be formed at every odd numbered wale and, due to the omission of the presser cams at these feeds, the yarns will be retained in the spring beards Il of the needles i1 and carried along to the next wale where they will be knitted o3 with the yarns of the next feeds B, D and "F", forming loose inlay loops 45. It will thus be seen that the noats 46 will alternate with the inlay loops 4I, as is clearly shown in Figs. 2 and 3.

At the three feeds "G", 1" and K, the long butt needles il will be up, which will cause iloats 4l to be formed at every even numbered wale and the yarns will be retained in the spring beards Il of the needles I6 and carried along to the next wales where they will be knitted oi'f with `the yarns of the next feeds H, "J" and L,

-ing a knitted fabric of repeating courses and wales as long as the machine continues to operate. It will be noted by reference to Figs. 2 and 3 that the oats 44 formed at odd numbered wales at feeds A, C and E, and the floats 48 formed at even numbered walesat feeds G, 1" and K will form run-resisting means for the fabric, and that the floats 48 and 48, and inlaid loops 45 and 41 will provide relatively loose floats and loops which may bereadily napped to give the fabric woolly characteristics. It will be further noted that the inlaid loops 45 and 41 and the floats 44 and 4l are all disposed on the rear surface of the fabric, and that the front surface of the fabric will be relatively smooth.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specinc disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to` secure Letters Patent, is:

l. An inlaid knitted fabric repeating every six courses, each repeat consisting of six separate yarns each knitted at every wale in one of said six courses, yarns floated at odd-numbered wales and inlaid at even-numbered wales in each of the first, second and third courses, and yarns floated at even-numbered wales and inlaid at odd-numbered wales in each of the fourth, nfth and sixth courses.

2. An inlaid knitted fabric repeating every six courses, each repeat consisting of six separate yarns each knitted at every wale in one of said six courses, yarns floated at odd-numbered wales and inlaid at even-numbered wales in each of a plurality of courses, and other yarns oated at even-numbered wales'and inlaid at odd-numbered wales in each of another plurality of courses.

3. An inlaid knitted fabric repeating every six courses, each repeat consisting of six separate yarns each knitted at every wale in one of said six courses, yarns floated at odd-numbered wales and inlaid at even-numbered wales in each of a phu'ality of successive courses, and other yarns floated at even-numbered wales and inlaid at `odd-numbered wales in each of another plurality
