The invention relates to woven Wire fabric and involves an improvement in means for hing ing together adjacent helical coils of such a (Cl. 24S-46) description, taken with the .accompanying draw ing wherein: Fig. 1 is a plan View showing a section of belt fabric and for providing wear resistant edges ing made in accordance with the present inven ' tion, with a portion thereof broken away; 5 5 for such fabric when it is used for belting. Fig. 2 is a side elevational View of the struc One of the primary objects of the invention is the provision of a hinging rod structure which ture shown in Fig. 1; Fig. 3 is a longitudinal sectional View taken is so designed that it serves not only as a hinge element between adjacent coil elements of the on the line 3_3 of Fig. l; and woven fabric, but is so constructed as to form 1 Fig. 4 is an inverted plan view of one of the wear resistant edges for they fabric when> it is hinging units, partly broken away. While the present improvements may be made up as a belt. 'I‘he use of a hinge rod for the purpose of connecting the helical coils of a woven wire fabric is well known. It has also been suggested heretofore that onev end of such a hinge rod be joined to the end of an 'adjacent hinge rod in such a manner that the rods of successive pairs are connected together at one end of the hinging unit. In such structures the 2 O unjoined ends of the rods which form the pairs are free to move laterally with respect to each other, so that the opposite edges of a belt con structed in this manner do not have the same ner as to be confined within the same marginal N 0 limits.- The adjacent ends of the two coils form ing this composite structure are welded together in one direction transversely of the belt. These disadvantages are overcome in the present im as shown at I2 and I3 in order to provide a rigid coil unit in which each coil element is held against movement with respect to the other. A plurality of such coil units are successively interwoven with each other to form a continuous length in a manner well understood in the art. provement by rigidly connecting the adjacent As will be apparent from the drawing, the loop degree of flexibility, resilience and stretch. Fur thermore, such structures provide no means for preventing endwise movement of the hinge rods ends of successive pairs of hinge rods- so that each of the pairs of rods forms a rigid structural unit, and the rods are restrained against end wise movement thereof in both directions with respect to the belt. 35 Another object of the invention is the pro vision of a wear resistant edge for wire belting, so constructed that the wear thereon when the belt is in use does not affect the coil elements of which the woven fabric is made. With such 40 a structure, the wear resistant elements may be made of a material which is more resistant to wear than the material of the coils, and they may be repaired or replaced at a cost much less 45 utilized with other forms of woven wire fabric and belting made therefrom, I have illustrated the same in the drawing in connection with a 15: fabric in which the helical coils are of a com posite character in that each coil element com -prises two independent coils I0 and II of similar structure and threaded together in such a man-_ than the cost of repairing or replacing the coils themselves. A further object of the invention is the pro' Vision of a wear resistant edge for a wire belt, so constructed that one edge of the wear resistant 50 element is positioned substantially in the plane of one surface of the belt in order to provide a con tinuous operating surface throughout the width of the belt. Still further objects and advantages of the im 55 provements will be apparent from the following portions I4 of the turns of the coils Iii overlap U and interengage with loop portions I5 of the coils II in the adjacent coil unit. It will also be ap parent that loop portions i6 of coils II overlap and interengage with loop- portions I'l of coils Ill in the adjacent coil unit. The loop portions 35 of adjacent coil units overlap to such an extent as to provide openings I8 extending transversely of the fabric for receiving hinge rods I9. As is well understood in the art, the tension which is exerted upon the loop portions of one of the coil elements by an endwise pull upon a belt of this character is transmitted through the hinge rod, and not directly, to the interengaging loop portions of the adjacent coil elements, to there by provide a more flexible belt structure. 'I'he hinge rods I9 are not attached to the loops, but extend freely through the overlapping por tions of the adjacent coil units and are thus freely movable with respect to the coils to provide a flexible hinge structure. Each of the rods pro jects outwardly beyond the opposite edges of the fabric as shown at 20. The adjacent ends of successive pairs of hinge rods are rigidly con nected together by means of short bars 2l made of wear resistant material and having the oppo '2,135,333 site ends thereof Weldedto theY projecting ends 20 of the hinge rods as shownrat 22. , of adjacent coils to forma continuous fabric, a hinge rod extending through each coil within 'I‘he bars 2|VV are preferably of such a length the overlapping portions of adjacent coils and » as to extend laterally slightly beyond the hinge` projecting slightly beyond the opposite ends of rods I9„and thelateral dimensions of the bars the coils, and-means rigidly connecting the pro are preferablysuch that one ,edge 23 is posi jecting.v ends of successive pairs of saidY rods to tioned'substantially injthe plane of the operating form wear resistant edges for said belt. 4.
