METAL FABRIC.

flriginal application filed October 21, 1908, Serial To all whom it may concern Be it known that I, AooLrH'F. RIETZEL, a citizen of the United States, add a resident of Charlestown, in the county of Washington and State of Rhode Island, have invented certain new and useful Improvements in Metal Fabrics, of which the following is a specification.

My invention relates to metal fabrics comprising members crossing one another and adapted for varioususes, as for instance, fencing, lathing, etc.

My invention is useful for metal wire fabrics and for such fabrics when constructed in roportions for use as fencing and, in setting forth the invention, 1 will, for purposes of illustration only, describe the invention as embodied in wire fencing.

Various expedients have been resorted to for securing crossing members of a metal fabric to one another at their intersections, such as the use of a piece of wire bent or coiled around the members of the fabric, or the bending of the wires of the fabric itself, or a simple welding of the crossing members of the fabric to one another at the point of intersection or the interweaving of the wires with a ring.

The object of my present invention is to provide a simple, cheap, rigid and yet light structure and one which may readily and conveniently be manufactured in an electric welding machine.

The invention consists in the construction of metal fabric, as hereinafter more particularly described and then specified in the claims.

'Referring to the drawings, Figure 1 shows a section of wire fencing constructed according to my invention. Fig. 2 is an enlarged side elevation at one of the intersections.

Fig. 3

is a vertical section through the strand member and fastener of Fig. 2. Fig. 4 is a vertical section through a strand memher and fastener of a 'modification. Fig. 5 is an elevation of another modification and Fig. 6 is an edge view of the same, one of the crossing or intersecting wires of the fabric being shown in cross-section. Figs. 7, and 8 illustrate some modifications in the form of the fastener. Fig. 9 illustrates a modification in which the fastener is applied to both sides of the fabric.

indicates the strand or longitudinal members of a metal. fabric and 2 the stay, crossing or transverse members of the fabric or vice versa.

as to be capable of engaging, by its side,

upon the sides of the crossing members 1, 2 of thefabric.

In Figs. 2, 4, 5, 7 and 8, the fastener is a single piece of wire cut to suitable length and bent to the desired form and so as to extend completely around the crossingpoint of'the fabric members 1 and 2 for making side contact with each of said members at two points located respectively at opposite sides of the crossingpoint. A' lateral bend or offset may be formed in one or both wires or members 1, 2, where they cross as at 5, in order that the wire fastener may more readily make contact by its side with the fabric at the four points surrounding the intersection when it is superposed on both members. The fastener might however lie between the fabric members as indicated in Figs. 5 and 6. This modification renders it unnecessary to bend either of the wires 1 and 2 or the wire fastener transversely to the plane of the fabric. might itself be slightly bent or distorted as shown in Fig. 4 to permit it to make side contact readily with both of the crossing members in case it is desired to make up a fabric without any bending of said members at the crossing point. When the fastener is a single piece of wire bent to form, its opposite ends 4 are preferably located over one of the- members 1, 2, and are side-welded at that point as shown in Figs. 2, 5, 7, 8, to prevent the ring or other endless form of fastener from opening or the ends from becoming displaced with reference to one another, as well as for securing greater rigidity or stiffness at all points.

The fastening piece of wire and the crossing members are superposed on one another at the intersections as shown in the various figures and the rounded side OffthQ fastening wire 3 engages the sides, bf the two crossing members of the fabric 1; points 7 and is welded thereto at such poi ts of contact by heating current and pressure applied sidewiseto-the fabric in a welding machine having suitable contact and pressure jaws Again the fastener I fabric members members have a rounded tion of an initial electric contact spot or point of limited superficial area Where the or electrodes. The pressure and contact electrodes of'such a machine are indicated at 6, 6 Fig. 3. In constructing the fabric, they are applied at opposite sides of the fabric in obvious manner and in addition to being of form to squeeze the fastener and together, at their points of side contact, they also feed an electric heating;1 current to the work which passes across sal of the fastener makes limited electric contact with the fabric members, thereby facilitating the heating of the parts to the weld ing temperature in the electric welding or unitingoperation.

y my invention a metal fabric of great stiffness and strength and small Weight may be produced at low cost. When the crossing side as in the case of a Wire fabric, this conduces to the formafastener crosses and makes contact by its side. with the, side of the strand or stay member.

Obviously for great strength a fastener may be applied to both sides of the fabric at the intersections in the manner already described in which cases the points of side contact on the two fasteners would preferably be opposite one another, as indicated in Fig. 9.

My present application constitutes a divicontact points where the rounded side sion of my prior application filed October 21, 1908, S. N. 458,818.

What I claim as my invention is:

1. A metal fabric having-crossing members and a fastening piece superposed on one another at the intersection and side- Welded together on the side of the fastening piece, said fastening piece lying between the crossing members.

2 A metal fabric comprising crossing Wires and a bent piece of fastening wire bent to extend completely around the crossingpoint, superposed on one another and having the bent wire side-welded to both crossing wires and on one of them at a point where the two ends of the bent wire meet.

3. A metal fabric comprising crossing wires and fastening pieces consisting of wire bent to surround the intersections, said fastening pieces being located between the crossing wires and side-welded to both of them.

4. A metal. fabric comprising crossing members and metal fasteners lying between the said members at their intersections and welded to both.
