KNITTED FABRIC FOR HYD RAULIC HOSE.

SPEGIFIGATION forming part of Letters Patent No. 630,783, dated August 8, 1899 Application filed February 9, 1897. Serial No. 622,602. (No specimens.)

. To ctZZ whom it may concern:

produce a knitted fabric suitable for the pur-' poses named and which shall be of uniform density and present smooth and compact su rfaces with no tendency to roll or curl in either direction.

The invention will be described first with reference to the accompanying drawings, and afterward the distinguished characteristics thereof will be particularly pointed out and distinctly defined in the claim at the close of this specification.

Figure 1 of the drawingsisaview showing in elevation a portion of a fabric embodying the invention, the threads being represented as separated from each other somewhat the better to illustrate the construction. Fig. 2 is a view in section on the line 2 2 of Fig. 1, looking in the direction of the arrows at the ends of such line.

The body of the fabric shown in the drawings is substantially like that shown and described in United States Patent No. 567,308, dated September 8, 1896, and comprises a knitting-thread 1, Warp-

threads

2 and 21, and weft-threads 3 and 31.

My improvement consists in the addition of a third weft-thread A, which splits the warp-threads, as hereinafter set forth.

The knitting-thread 1 is knit in rib-stitch that is to say, the alternate vertical wales or lines of stitches formed thereof are located on the opposite faces of the the fabric, as is clearly shown in Fig. 2, the wales or lines 11 being at one face of the fabric, while the wales or lines 12 are at theother face thereof.

The set of warp-threads 2 is located between the wales or lines of stitches 11 of the one face of the fabric, while the set of warpthreads 21 is located between the Wales or lines of stitches 12 of the other face thereof, the respective warp-threads of a given set thereof alternating in.position with the wales or lines of stitches of the corresponding face of the fabric. Thus in the fabric shown in the drawings the spaces between the ribs on the opposite faces of the fabric are occupied and filled by the warp-threads.

' The Warp-threads are held in place by the weft-threads 3 and 31, which latter lie at the two faces ofthe fabric outside of the warpthreads, and in turn the weft threads are bound by the loops or stitches of the knittingthread 1, all as is clearly shown in the draw ings.

As will be perceived from inspection of the drawings, my fabric, as there shown, is of uniform density, and the surfaces thereof are smooth and compact.

While I have shown and described but a single knitting-thread and two weft-threads as embodied in the fabric, it will be under stood that in practice I contemplate producing the fabric on a knitting-machine having two or more knitting-feeds, at each of which will be supplied a knitting-thread and two weft-threads, as aforesaid. These additional feeds will not change the construction of the fabric. In other words, for the sake of economy and to expedite the production of the fabric I contemplate employing in the machines two or more duplicate feeds, eachfeed comprising a knitting-thread 1 and weftthreads 3 31. This will be understood as being in accordance with the principles of modern practice in knitting and. involves no departure from the spirit of my invention.

To further strengthen, thicken, and solidify the fabric, my present invention comprehends laying between the warp-

threads

21 and 2, to thus split them, athird weft-thread A, which splits the warp-threads.

So far as known to me, I am the first to introduce three weft-threads at each of the feeds of a rib-machine, thereby to produce a novel rib fabric, as here disclosed,'- having'.

three weft-threads for each spiral row or series of knitting-stitches, and especiallywhen warp-threads are introduced at both-sides of the fabric, as here disclosed.

between and splitting the warp-threads, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE E. STEVENS.
