This invention relates to improvements in wire fabric which is particularly designed for use as conveyor belts, aprons, screens, and the like; the generalobject of the invention being to produce a wire fabric of maximum flexibility and great tensile strength and one in which the interstices are very small.

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 drawings, and specifically pointed out in the appended claim.

In-describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote likeor corresponding parts throughout the several views, and in which Fig. 1 is a perspective view, showing the improved fabric used as a conveyor belt;

Fig. 2 is an enlarged detail view showing how the fabric is formed;

Fig. 3 is a View showing how two left-hand spirals are connected together by a rod with a right-hand spiral between them;

Fig. 4 is a view of one of the left-hand spirals; i Fig. 5 is a view of a right-hand'splral;

Fig. 6 is a view of one of the staples;

Fig. 7 is an end view of portion of the fabric; and

Fig. 8 is a sectional view through part of the fabric.

As shown in these drawings, the fabric is composed of a plurality of spiral coils of wires 1 and 2, which may be termed the warp of the fabric, and the staples 3 which connectthe spirals together. The spirals 1 have their coils inclining to the leftor are left-hand spirals while the coils of the spirals 2 incline to the right or are right-hand spirals, and the spirals 1 are alternately arranged with the spirals 2 with one limb 3 of each staple connecting together each pair of the spirals 1, andthe' other limb 3 of each staple connecting together each pair of the spirals 2. As shown, the spirals are flattened and the limbs of the staples pass through the. vertices of the spirals, and these limbs als pass through the spirals, the vertices of whici are. engaged by the opposite limbs, intermediate the ends of said other spirals, with parts of each spiral entering the spaces between the coils of the adjacent spirals. Thus the parts are closely arranged together as shown in the drawings to provide a fabric, the interstices in which are very small.

The closed ends of the staples prevent any portion of the coiled wire from being unwound at the ends, and the extremities of the staples may be bent around the outer coils of the spirals to hold the staples in place and to prevent the coils from unwinding adj :icent the free ends ofthe limbs of the stap es.

As before stated, this arrangement of parts produces a wire fabric of open mesh and which has great flexibility and tensile strength. The fabric can be made endless and used as a conveyor belt, as shown at A in Fig. 1, or its ends may be separated if desired. A

It is thought from the foregoing description that the advantages and novel features of my 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 claim.

What I claim is A wire fabric formed of wires twisted into spiral shape, some of the spirals being righthand ones and others left-hand ones, the right-hand spirals being alternately ar ranged with respect to the left-hand spirals,

and staple-shaped wires connecting the spirals together, one limb of each staple passing through the vertices of each pair of righthand spirals, and the other limb of each staple passing through the vertices of each pair of left-hand spirals.

In testimony whereof I afiii: my signature.

EDWARD F. PINK.
