E. F. PINK WIRE FABRIC Oct. 4,1932.

v Filed Nov. 14, 1928 Patented Oct. 4, 1932 EDWARD F. PINK, F CAMBRIDGE, MARYLAND Winn rAnRIc Application filed November 14, 1928. Seria1;No. 319,379.

This invention relates to improvements in wire fabric, such as is used for conveyor belts, aprons, screens and the like, the general object of the invention being to provide a rein- 5 forced selvage edge to such fabric which will act to protect the edge of the fabric and also increase its tensile strength.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a plan view of a length of wire fabric provided with the improved edges;

Figure 2 is an edge view of Figure 1;

Figure 8 is a view similar to Figure 1, but showing a modification;

Figure 4 is an edge view of Figure 3; and

Figure 5 is a detail perspective view illustrating the connecting of the wire strands to a link of'a chain in my modified form of invention.

In these views, the numeral 1 indicates a length of wire fabric and 2 indicates a chain placed at each side edge thereof, each chain being composed of a plurality of links 3 preferably of the construction shown and which consist of a member looped upon itself so as to form a pair of limbs 4. The ends 5 of the wires forming the fabric are placed between these limbs of the links with their extremities flush with the outer edges of the links or substantially so, and the ends are suitably connected with the links, such as by brazing,

soldering or the like.

In the modification shown in Figures 3 and 4, the links are set on edge instead of being flat, as in the first form of the invention, and the ends 5 of the wires 11 forming the fabric extend through the eyes 6 of the links instead of in the limbs, as in the first form. The ends of the wires are brazed, soldered or otherwise connected with the links. Thus it will be seen that by connecting the links of the chains with the ends of the wires of the fabric, a reinforced selvage edge is provided for the fabric which will not only protect the edge of the fabric, but will also increase its tensile strength.

Attention is called tothe fact that the ends of the wires pass through the links either when the links are arranged fiat, as shown in Figures 1 and 2, or when they are arranged on edge, as shown in Figures 3 and 4, with the ends of the wires substantially flush with exterior portions of the links, so that the wires can be secured to the exterior parts of the links. By attaching these chains to the edges of the fabric, danger of the fabric becoming unraveled is eliminated.

As will be seen, each end of each pair of wires is attached to a link at the center of the link so that the chains will not interfere with the flexibility of the fabric.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1* I 1. A. wire fabric for belting comprising transversely arranged coiled interwoven strands for forming a flexible fabric, said I strands arranged in pairs with their end portions extending beyond the side edges of the fabric in parallel and contacting relation, chains including links arranged at the side edges of the fabric with the end portions of each pair of strands extending through opposite links of the chains, said end portions after extending through the respective links being bent at right angles to each other and in opposite directions toform attaching portions engaging faces of the links, and means rigidly fixing the attaching portions to the faces of the links. a

2. A wire fabric for belting comprising transversely arranged coiled interwoven strands for forming a flexible fabric, said strands arranged in pairs with their end portions extending beyond the side edges of the fabric in parallel and contacting relation, said pairs of strands hinging on each other to provide flexibility to the fabric, chains including pivotally connected links arranged at the side edges of the fabric with the end portions of each pair of strands extending through opposite links of the chains and rigidly fixed thereto with the pivots of the links arranged in transverse alinelnent with the hinges between said pairs of strands.

3. A wire fabric for bel'ti'ng comprising transversely arranged coiled interwoven strands for forming a flexible fabric,said strands being arranged in pairs and hinging on each other to provide flexibility to the fabric, linked elements arranged at the side edges of the fabric with the end portions of each pair of strands fixed to opposite linked elements and with the pivots 0f the linked elements arranged in transverse alinement with the hinges between said pairs of strands.

In testimony whereof I afiix my signature.
