METAL FABRIC.

SPECIFICATION forming part of Letters Patent No. 759,760, dated. May 10, 1904:.

Application filed February 28, 1903. Serial No. 14:53:58. (No model.)

To all whom it may concern:

Be it known that LPETER J. SI-IRUM, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Metal Fabric, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a top plan view, partly in section, showing one form of my mat constructed in accordance with my invention. Fig. 2 is a detail View showing the method of forming a section. Fig. 3 is a perspective view of the hinge-rod. Fig. 4 is a side elevation showing a portion of the mat. Fig. 5 is a top plan View showing another form of the invention. Fig. 6 is a perspective view showing a portion of one of the bent strips of the Fig. 7 is a plan view, partly in section, showing another form of the mat. Fig. 8 is a side elevation of the form of Fig. 7, and Fig. 9 is a detail view showing the manner of weaving the mat fabric of Fig. 7.

My invention relates to metal fabrics, especially those used in the class of metallic mats, and is designed to provide a light, attractive, and strong mat or fabric which may be cheaply and rapidly formed. It is also designed to provide for using plugs of rubber or other material, thus enabling me to utilize waste material in the fabric and increase its nonslipping and other desired qualities.

In the drawings, referring to the form of Figs. 1 to 4, inclusive, 1 show a mat formed of sections hinged together, each section formed of wire twisted about circular disks or plugs. In this form I twist the wires 2 20f each section together for a short distance, then bend them apart into circular form with hinged loops 3 3 at each side, then twist them together at 4c, and so on for the width of the mat desired. In the holes or meshes thus formed I place plugs or disks 5, which are preferably cut from rubber, such as old wornout rubber mats, though wooden plugs or other material may be used for the purpose. These plugs may either be inserted after the section is twisted or preferably the wires are Woven around the plug during the forming of the meshes. The wire meshes firmly bind and hold the plugs in place. The sections thus formed are hinged together, preferably by threading the hinge-rod 6 through the eyes 3 of adjacent sections, the end of the hinge-rod then being bent back or looped, as shown at 7. I may, however, use separate rivets or connections between the pairs of eyes.

In the form of Figs. 5 and 6 the units are formed of flat metal strips, and in this case the strips 2 are bent into semicircles, then twisted and flattened to form the portions 4!, then bent into semicircles, and so on throughout their length. The two strips are then woven or interlaced, and between the flattened twisted portions 431 insert connectingpieces 8, formed of short strips with intermediate flattened portions twisted into a horizontal plane. The ends of these short connectors are perforated, and each section is hinged to the next by rivets 9, extending through these perforations. I have shown in this form the plugs 5 held between the two curved or semicircular portions of the strips of each section, and I prefer to use the plugs, though they may or may not be used in this form, as desired.

In the forms before described a flexible hinged mat is provided; but I may use the plug and wire or strip construction without hinging sections together to give flexibility. Thus in Figs, 7 8, and 9 I show the plug 5 as secured within the meshes of a twisted-wire fabric 10. The method of weaving this fabric is illustrated in Fig. 9, the plugs being pinched and held securely within the meshes either by weaving the meshes about them or by forcing them into the meshes after the fabric is woven. The wires are preferably woven to form the twisted portions 11 between the plug-holding portions, as shown.

The advantages of my invention will be apparent to those skilled in the art. The plugs add greatly to the non-slipping quality of the mat. The mat in its preferred form may be rolled up and presents a neat and attractive appearance, while being strong an d long-lived. The plugs may be made from waste material and may be replaced when worn out. he fabric is strong and may be used for machinebelts and other purposes.

Many variations may be made in the form and arrangement of the meshes, the manner of securing the plugs, the method of hinging where this is used, &c., without departing from my invention.

I claim 1. A metallic fabric comprising a plurality of interwoven strips forming open meshes, each mesh being bounded by port-ions of different strips, and plugs held in the meshes by such portions of the different strips; substantially as described.

2. A mat formed of units hinged together to give flexibility, each unit having inter woven strips forming meshes containing plugs, the sections having hinge members pivotally connected together; substantially as described.

3. A mat formed of sections hinged together to give flexibility, each section consisting of a metal fabric with open meshes, each bounded by a plurality of strips and having oppositelyprojecting hinge members, plugs held within the meshes, and means forhinging the sections together; substantially as described.

4. A fabric formed of sections hinged together to give flexibility, each section containing a wire fabric with open meshes containing plugs, and having twisted hinge-loops; substantially as described.

5. A metallic mat formed of a wire fabric with open meshes formed by a plurality of wires, plugs held in the meshes, and twisted portions holding the fabric between the meshes; substantially as described.

In testimony whereof I have hereunto set my hand.
