8 Claims.

This invention relates to fabrics of the woven coil wire type and has for thev primary object the provision of means located within the fabric and extending from opposite edges thereof inwardly of said fabric and terminating within the latter to provide the fabric with selvages adapted to prevent the fabric from tearing or becoming out of shape and which will not affect the flexibility of the fabric or materially increase the cost of manufacture thereof.

Another object of this invention is the provision of coil strands of the same formation as the coil strands of the fabric andscrewed into or interwoven with the strands of said fabric from opposite edges of the latter inwardly of the fabric to provide reinforcing selvages to the fabric with means also .cooperating therewith to strengthen the fabric at its selvages for maintaining the reinforcing strands in the -same plane with the strands of the fabric so that the reinforcing strands will not drop outwardly of the strands of the fabric during theuse of the latter.-

With these and other objects in view this invention consists in certain'novel features of construction, combination and'arrangement of parts to be hereinafter. more fully described and claimed.

For a complete understanding ofA my invention, reference is to be hadto the following description and accompanying drawing, in which Figure 1 is a fragmentary plan view illustrating a fabric constructed in accordance with my invention.

Figure 2 is a fragmentary plan view showing vthe reinforcing strands woven with one another and with the strandsof the fabric.

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a similar view taken on the line 4-4 of Figure. 1.

Figure 5 is a perspective view illustrating one of the reinforcing elements.

Referring in detail to the drawing, the .numeral 10 indicates a woven wire fabriccomposed of coiled wire strands l1 woven or screwed one into the other. The strands l1 may be of either right hand coiled formation or left hand coiled Vformationand the ends of said strands are suitably secured together in pairs either by welding, knuckling or in any other manner well known in this art. A fabric thus constructed is useful for many purposes and primarily for the making of endless conveyor belts.` The strands ll of the fabric extendtransversely of the belt when the fabric is employed for this purpose and if desired and at spaced intervals of the fabric, reinforcing rods 12 may be extended through the con-v volutions of pairs of the strands, as illustrated in Figure 1, by a single rod having its ends secured to the ends of the respective pair of strands,

.(Cl. 24S-6) yfor the purpose of reinforcing the fabric and aiding in preventing the fabric from shrinking or spreading out of shape due to excessive strains' or loads thereon..

To prevent tearing and to strengthen the fabric my invention is employed and consists of selvages for the fabric, as clearly shown in Figure 1. The selvages .are constructed from coiled wire strands 14 of the same formation as thestrands .11 and the strands 14 of each selvage are woven or screwed one into anotherand also into the strands 11. -The strands14 are approximately of the same length and much shorter than the strands 11 so that the inner ends of the strands 14 terminate within the fabric and alsowithin the convolutions of the strands 11. The outer ends of the strands 14 are connected in pairs by welding or knuckling. The outer ends of the .strands 14 terminate in alignment with the ends of the strands 11. The strands '14 afford maxi- Ymum strength to the fabric where employed therein and do not prevent such portions of the fabric which ha've the strands woven therein from flexing. The strands 14 due to their connections'in pairs will be prevented from working out of the fabric or transversely of the fabric to any appreciable extent.

Elements 15 of substantially hairpin shape are passed into the convolutions of the strands 11 and 14 at the selvages of the fabric. Each element is composed of connected parallel leg portions and one leg portion lies in the convolutionsof the reinforcing strand 14 and the other leg portion lies in the convolutionsof the fabric strand llxinterwoven with the strand 14 so that the strands 11 and 14 will be maintained in the same plane, obviating the reinforcing strands 14 from dropping out or moving laterally of the strands 10 during the use of the fabric and especially when employed in the construction of conveyor belts, where the strands 14 would have a tendency to drop out of the strands 1l and present unevenness to the opposite faces of the belt. The elements 15 being constructed from flattened material, as shown in Figure 3, more readily maintain the strands 11 and 14. in the samehorizontal plane as said elements contact `with opposite sidesof the convolutions of the strands. The elements are inserted in the conv'olutions of the strands before the connecting `of the ends of the strands and are prevented from'moving out ofthe fabric by the con- -nected ends of thestrands. Theends of the elements 15 terminate in the fabric in substantial alignment with the inner ends of the strands 14. However, said elements. may be made. to-extend further into the fabricand would then reinforce the strands 11 of said fabric to a greaterextent.

The connected ends of the strands 11 and 14 and the connecting portions of the elements 15 form wear resisting edges to the selvages capable of effectively resisting wear and also materiallyr preventing the fabric from tearing at the edges when the fabric is employed in conveyor belts and which during use crowd or bear against guides and rollers placing thereon forces acting to wear or tear the belt.

Having described the invention, I claim:
