designed to maintain its position on the driving pulleys or rolls as contradistinguished to the pulleys in its movement; to provide a wire fabric belting'in which the edging or selvage, .while maintaining the elements of the fabric intact, permits freebending of the fabric, so that it may readily pass around the rolls or pulleys in close contact'with the peripheral surface thereof; and' the Figure 3 is a sectional view taken on the plane indicated'by the line 3-3 of Figure l.

The improved fabric is constructed of a series of intercurrent right and left hand wire coils 10 and II, which are coupled together by means ofsinuous cross connectors l2 formed of wire strands. The coils l and 'II are open coilsthat is, their convolutions are separated and, cross-sectionally, are of oval form, as clearly shown in Figures 2 and 3. The oval form of convolution makes for a belt or fabric of generally fiat form, as distinguished from the form that convolutions .of the connected coils l0 and H rest, the convolutions of the adjacent coils lying in successive oppositely disposed seats inthe cross connectors, to maintain spacing of the, coil convolutions.

formed with eyes l3 engaging the terminal seats of the cross connectors |2..

' Selvaging ofthe' fabric is accomplished by means of links [4 and I5 arranged in intercurrent relation along the side edges of the belt or fabric; these links'being made of wire strands of preferably the same gauge as that of which the The terminal convolutions of the coils are ties of the strand in opposite directions. The links I4 bridge each successive pair of cross connectors I2 and are preferably. welded or otherwise secured to the extremities thereof. The links l5 bridge'adjacent connectors of adjacent pairsbut, having eyes'formed in, the same manner as those of the links l4, are preferably loosely mounted on the connectors and are retained in position there-'- on by the rigidlyjconnectedlinks I l. The links M are preferably mountedv correspondingly on the several connectors, as are the links I5 on the connectors with which they engage, butthe manner of mounting the links l5'is preferably the reverse of the manner of mounting the links HI, so that the selvage provided by the series of links follows a sinuous line of regular form as clearly shown in Figure 2.

Constructed as described, the belt or fabric comprises a series of alternate units each made up of a coil ID, a pair of cross connectors l2 and a pair of oppositely disposed links 14 which constitute substantially an. assemblage of rigidly connected elements. These separate units are interconnected by the coils I l and their associated links I5. But this arrangement of parts provides for free relative swinging movement of interconnected units, so that the belt or fabric may readily conform itself to the periphery of the engaged pulley or roll and the edging provided by the links l4 and IS, in conjunction with the seats formed in the cross connectors, is means to prevent lateral displacement of the units while taking up but a minimum space at the side edges of the belt, so that the belt need be no wider, practically, than the width of the desired working area'thereof.

' The invention having been described, what is rent right and left hand wire coils having the convolutions thereof uniformly spaced, sinuous wire cross connectors threaded through'the convolutions of adjacent coils, and a selvage comprising links bridging the extremities of successive cross connectors, certain of the links being loosely mounted on the cross connectors and the remaining links beingrigidly secured to said cross connectors and maintaining the loosely mounted links in place. I x 2. A wire fabric comprising a series of transversely arranged wire coils, cross connectors threaded alternately through the succeeding convolutions of adjacent coils, and a selvage for the fabric comprising links bridging the extremities of adjacent connectors and being in part rigidly connected with said connectors and in part loosely connected with the same.

3. A wire fabric comprising a series of transversely arranged wire coils, cross connectors threaded alternately through the succeeding convolutions of adjacent coils, and a selvage for the fabric comprising links bridging the extremities of successive pairs of cross connectors to which they are rigidly connected, and additional links arranged in intercurrent relation with the first said links and bridging but being loosely connected with the adjacent connectors of adjacent pairs.

4. A wire fabric comprising a series of transversely arranged wire coils, cross connectors threaded alternately through the succeeding convolutions of adjacent coils, and a selvage comprising a series of links formed of wire strands terminally bent to provide terminal eyes, said cross connectors having their extremities passed through the eyes of the links and the alternate links being rigidly secured to the connectors while the intervening links are loosely engaged therewith.
