KNITTED FABRIC.

Application led May 24, 1919. Serial No. 299,595.

To all whom t may concern:

Be it known that I, EDWARD H. WALTER, a citizen of the United States, residing at |VVoodlynne, county'of Camden, and State of New Jersey, have invented a new and useful Improvement in Knitted Fabrics, of which the following is a full, clear, and exact del scription, reference being had to the accompanying drawings, which form a part of this specification. i s

The object of m invention is to producey a knit fabric one ace of which is dominatingly of one material or color while the other face is dominatingly of another material or color. Another object of my invention is to provide a fabric comprising two threads or series of threads, which may have thesame or different characteristics, and a third thread having differential characteristics, as, for example, a fabric with a silk face, a cotton body and a woolen backing, the latter, if desired, being napped by a subsequent operation.

A preferred embodiment of my invention is shown -in the accompanying drawings, wherein- Fig. l is a front view of the fabric showing the general appearance.

Fig. 2 is a greatly enlarged view of a portion of t-he same showing the appearance of the stitches on the front of the fabric.

Fig. 3 is a view similar to Fig. 2 showing the appearance of the stitches on the back of the fabric.

The fabric comprises a series of longitudinally extending warp threads a, a, etc., each of Which is interlooped with itself and with the binder weft thread; a transversely extending weft thread I) interlooped with `the warp threads and successive ,'courses of which are interlooped with each other, and (in order to secure all the advantages of the invention) a backing weft thread c which lies against one face of the fabric and is held or bound in by the warp threads a.

Reference to the Fdrawings will make it clear that the binder weft thread b, considered apart from the remainder of the fabric, forms a self-contained fabric which, structurally, is the same as an ordinary plain knit fabric such as is customarily made on` standard knit-ting machines of either the fiat or circular type. That is, the thread b extends alternately back and forth along the fabric. The yokes of the loops of each course extend around the necks of the loops of an adjacent course, forming longitudinally extending wales of loops.

Each warp thread a comprises a self-con tained chain of loops. Starting with any given loop, the thread .extends upward, around and downward to form a second loop; then through the first or given loop, upward, around in the opposite direction and downwardA to form a third loop; then through the third loop, upward, around, again reversing direction, and ldownward to form a fourth loop and so on. It will be` noted that in forming adjacent loops the thread travels in opposite directions.

The loops formed by the warp threads a are, respectively coincident with the loops formed by the weft threads b, and wherever `a warp thread extends through its own loop it coincidentally extends through a weftI thread,loop, thereby uniting each wale of Warp thread loops to the correspondingA Wale of weft thread loops. In the fabric illustrated, the warp threads a extend in front of the weft thread b throughout, except just before a` warp thread reverses its direction of extension to extend through coincident warp thread and weft thread loops to form its own loop.

The backing weft thread c extends back and forth with weft thread b, there being as many shots of thread a as there are shots of weft b. Thread c, however, is not interlooped with the other threads, but extends substantially straight, being virtually laid upon the back of thev fabric and being bound in by the warp threads (t where they temporarily pass to the back of the fabric preparatory to forming theirloops, as above described. u

A typical fabric embodying the above construction comprises a facing warp a of silk,

a binder weft b of cotton and a relatively thick backing thread o of wool. Such a fabric presents a silken appearance and feel on its face, it is rendered structurally strong and complete by the relatively.inconspicuous cotton binder, .while -great warmth is imparted to the fabric by the substantially concealed woolen backing. If desired, the fabric may be napped `on its back in the manner known in the art. Fabrics of man f other characteristics may be knit in accor ance With my invention. y

It Will be understood that the invention is not limited to the plain knit fabric illusvtrated, the invention residing not in any particular stitch or loop, but in the interlooping and interweavin' of the threads as hereinafter claimed. s an exampler of a permissible and obvious deviation, the threads may be manipulated at intervals, to form tuck stitches, in the manner Well known in the art.

The improved fabric may be knit by hand,

Known machines must be Having now fully described my invention, what I claim and desire to protect by Letters Patent is: I

A knitted fabric having a weft thread which extends alternately back and forth and which forms transversely disposed rows of loops and vertically-disposed Wales, the loops of each row o weft being interlocked with the loops in the adjacent rows, and a plurality of longitudinally disposed looped Warp threads, each Warp thread being looped with a different loop in each row of weft loops and in a different Wale in each row, the adjacent loops of the Warp threads being reversed-With relation to each other.

In testimony of which invention, I have hereunto set mv handVat Philadelphia, on

this 22nd day of May, 1919.
