wlan-CLOTH.

SPECIFICATION forming part of Letters Patent No. 450,165, dated April 14. 189] Application led July 3l, 1890. Serial No. 360,530. (No model To all whom, it may concern:

Be it known that I, JOHN W. LI'r'rLEEIELD, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in lVire-Cloth, of whichv the following description, in connection with the accompanying drawings, is a specification,like letters on the drawings representing like parts.

Prior to this invention what is known commercially as wire-cloth has been woven in a loom, the warp and weft being composed of single strands of wire, the said strands being coarse or fine, according to the fabric.

A This invention has for its object the production of a strong wire-cloth which shall, however, be very flexible longitudinally; and to accomplish this I employ a wire Warp composed each of sever-al strands of wire braided together. The wires when braided together loosely are not stiifened, yet their accumulation aords the necessary strength and leaves the fabric produced flexible longitudinally and strong. The wire forming the weft may be braided or otherwise.

Figure l shows enlarged a piece of wirecloth embodying my invention; and Fig. 2 shows a modification to be referred to.

The wire cloth or fabric shown in Fig. 1 is made from warps A and weftB interwoven or united asone Wire.

in the usual manner. composed of several small wires cm. a., braided These warpsAin Fig. l are united by the weft B, and therein the weft is shown as composed of several strands b b ZJ, braided or united together. The warps and weft are crossed one over the other; but the several separate strands of the warps and weft are not interlocked or interlooped one with the other at these crossing-points. The weft maybe a single strand, as in Fig. 2, and yet leave the fabric flexible longitudinally. It is obvious that if the wire-cloth should be made very wide the weft might be of braided wire and the cloth be cut up in lengths and the weft be run in the line of greatest strain.

A Wire fabric composed of warp and weft, at least one of which is of braided wire, the warp and weft being crossed one over the other without interlocking at their intersections, substantially as described.

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

JOHN W. LITTLEFIELD.
