1 Claim.

One object of this invention is to provide arun-resisting fabric including plain stitches and tricks having a ribbed surface on one side forming an improved and highly attractive appearance.

A further object is to provide a fabric of the above nature made with a machine in which the closing of the needle beards is controlled by a series of pressers and presser cams of special shape, and so arranged as to omit the pressing of 5 the beards of certain needles so as to cause said needles to form tucks instead of casting oif the old loops.

A further object is to provide knitted fabric of the above nature having a linenlike appearance, which will be simple and easy to manufacture, flexible, having good elasticity in the width, which will not sagflinthe length, which will be .non-crushable, and very efiicient and durable in use.

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

In the drawings: Fig. 1 represents a diagrammatic plan view of a circular knitting machine upon which the improved fabric may be constructed.

Fig. 2 is a table showing the relative arrangement of the pressers and presser cams, and giving the sequence in which the stitches and tucks will take place in the respective wales and courses. y Y v c Figure 3a is a perspective view of a plain" presser cam.

Figure 3b is a perspective view of a high cut 40 presser cam.

Figure 3c is a perspective view of a low cut presser cam. e

Fig. 4 is a fragmentary perspective view of the twelve beard pressers arranged in sequence. I

Fig. 5 is a side fragmentary view showing the engagement of a low cut presser cam with a low cut presser, the needle beard being closed and casting off the stitch.

50 Fig. 6 is a similar view showing the engagepresser, the needle beard remaining open for making a tuck.

Fig. '7 is a similar view showing the engage- 55 ment of a high cut presser cam with a low cut .presser, resulting in the closing of the needle an improved.

ment of a low cut presser cam with a high out p presser, also allowing the needle beard to remain open for producing a tuck.

Fig. 8 is a similar view showing the engagement of a high cut presser cam with a high cut beard and casting off the stitch.

Figs. 9 and. 10 indicate the appearance of the front and rear sides of the improved fabric, re-

' spectively.

Fig. 11 is a view on an enlarged scale showing the stitch structure of the knitted fabric.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral III indicates a series of identical needles which are carried on a rotating cylinder, not shown, said needles being independently raised and lowered, at each knitting point by suitable cams, not shown, as in ordinary practice.

Each of the needles I0 is provided at its upper end with the usual spring beard H which is adapted to hook over the yarn or thread to form loops in the knitting operation. Located between the successive needles III are the usual cam-operated sinkers, not shown. Provision is also made of a plurality of beard closers or pressersone for each needle 1-, which are adapted to close'the needle beards [I when moved by the presser cams to be hereinafter described.

The beard closers or pressers are made in two forms; i. e., low cut, as indicated by l2, and high cut, as indicated by IS. The low-cut pressers l2 have slots it cut in their edges a short distance from the upper ends thereof, while the high cut pressers have their upper corners removed, forming angular slots I5, the

slots l4 and 15 being located at different heights and out of alinement with each other.

The presser cams are made in three difierent forms; 1. e. plain, low-cut, and high out", as 40 indicated in Fig. 3 by the numerals l6, l1 and I8, respectively, In the low cut presser cam I! the lower front corner is removed to provide an as:

gular recess l9 while in the high cut pressure cam it, the upper front comer is removed to provide an angular recess 20.

The low and high cut pressers l2 and I3 are arranged in succession around the knitting machine in the sequence indicated in the top horizontal row of the table of Fig. 2; to wit: L--L-- H-LHLI-I-H-LH-L-H, this sequence being repeated over and over again. This arrangement is also shown in Fig. 4.

The plain presser cams IS, the low cut presser cams- I1, and the high cut presser cams II are 55 located at the knitting points, and as shown in Fig. l, are arranged in the sequence given in the right-hand vertical column on the table of Fig. 2; to wit: P-H-L-L-LLPH+LL'LL. The locations of the twelve presser cams employed are clearly shown in Fig. 1.' The pressers and presser cams are so arranged that whenever a plain presser cam I 6 engages either a low cut presser I2 or a high cut presser [3, a stitch will occur; whenever a high cut presser cam I8 engages a low cut presser II, a tuck will occur; and the same result will also take place when a low cut presser cam I'I engages a high cut presser l3. In all other cases, the yarn will be cast off. The arrangement of the stitches and tucks thus produced in the knitted fabric is clearly indicated by the tabulation in the body of the table of Fig. 2, and the actual appearance of the fabric is shown in Figs. 9 and 10; Figs. 5 and 8 represent two of the conditions when stitches will be produced, while Figs. 6 and 7 indicate when tucks will occur.

In Fig. 5 the engagement of a low cut presser .cam with a low cut presser causes the needle beard to be closed, and the same result takes place in Fig. 8 where a high cut presser cam engages a high cut presser. In Figs. 6 and '7, however, the needle beards will remain open due to the fact that a low cut presser cam en- 22, 23, 2|, 25, 26, 21, 28, 29, 3|], 3| and 32, respectively in Fig. l. The strands are delivered to the needles 10 through the usual guides 33 and 34.

It will be noted by referring to Fig. 9 that than an attractive ribbed ratine or boucle" appearance is produced on the front of the fabric, and it will be understood that this construction contributes to run-resisting properties thereof. I While there has been disclosed in this specification one form in which 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 specific 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 claim.

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

A run resisting knitted fabric repeating every six courses and'every twelve wales, which comprises a yarn knitted in each of said wales in the first course, a yarn tucked in two wales, knitted, tucked, knitted, tucked, knitted in two wales,

tucked, knitted, tucked and knitted in that order,

in the said twelve wales of the second course, and four yarns, one in each of the third, fourth, fifth and sixth courses, knitted in two wales, tucked, knitted, tucked, knitted, tucked in two wales, knitted, tucked, knitted and tucked, in that order,

the said twelve wales of said four yarns.
