WIRE MAT.

SPECIFICATION forming part of Letters Batent No. 532,508, dated January 15, 1895.

Application filed December 1, 1893. Serial No. 4921538. (Model.) K

My invention relates to woven wire fabrics i for employment in fencing, oflice railings and screens, and particularly indoor-mats.

Y The object of this invention is to increase the durability of a finished piece of fabric by.

thoroughly securing the edges thereof, my particular object being to provide a firm and durable, but at the same time iiexible and neat appearing border for the fabric. i

My invention will be more readily under! stood by reference tothe accompanying drawings, in Whicht Figure lV illustrates a portion or section of a piece or mat of wire fabric provided with a borderembodyingmyinvention. Fig.2shows a slightly modified construction. Fig. 3 illustrates the position and form of the locking parts of the fabric edge and the border. Fig. 4 illustrates the substitution of sheet metal for wire in the border. In the drawings, I have illustrated my border as applied to a fabric of the particular construction shown and described in my Letters Patent No. 507,865, dated October 3l, 1893, but it may be understood that my border may be applied to any fabric which from its formation exhibits a series of notches or indentations in its edges.

The fabric shown is composed of a series of primary and transverse coils 2 and 3 arranged at right angles to each other in such manner that all parts intersect and interlock with the others and are -firmly held in place at the edge of the fabric, as shown in Fig. l. The last coil 5 parallel to the edge intersects with the turned ends 7 and 9 of'these coils which extend at right angles thereto. The border coils ll are coiled in an opposite direction to the last parallel coil 5 of the edge and are of such in Fig. 3, and the inwardly curved parts 7.

and 9 of the transverse coils form so much of a bar as is necessary to effectually prevent the pulling out of those parts of the border contained therein. A

Where, as shown in Fig. 2, the last parallel coil of the fabric is omitted, the ends 7 and 9 of the transverse coils collapse slightly upon one another, and thus permit the insertion of an extra or additional coil in the border. The bordel` coils are preferably of the same pitch as the coils making up the fabric. The closely pressed series of coils complete a practically full and solid, but flexible, border or roll upon the edge of the fabric and entirely cover the sharp point-s or ends of the fabric wires from sight and touch. As the border coils do not interlock with any part ofthe fabric, the border may be very readily removed by simply uncoiling one or more of the coils of the group, after which the remainder will slip out of the notches in a body. The coil or group of coils which make up the solid border roll may be forced into place in the notches by pressure, or they may be coiled into place one after the other, the last coil pressing' forward the others and completely filling successive gaps or notches. 'Ihe latter 'method is preferred owing to the great power which is necessary to force the coils laterally against the edge of the fabric and into the notches.

The wires ofthe border and fabric are coiled in opposite directions, that is to say, if the fabric is made up of left hand coils, the border is of right hand coils, andv vice Versa. This is essential, as a border formed of wires coiled in the same direction as the body of the fabric could not be connected to the edges of the fabric-bytlling the spaces between the ends of the wires in the manner shown and described by applicant.y

In place of using aseries ot' coils of wire to make up the border, I may substitute the sheet metal coilll composed of a strip of metal IOO of the same width as the group of coils of which it takes the place. (See Fig. 4.)

A further and greater advantage than that of simple neatness lies in the fact that the solid border perfectly locks the ends of the coils extending into the same, thusprevenb ing the loosening or uncoiling of the wires. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with the woven Wire fabric, of a border coil confined in the edge thereof and filling the spaces between the intersections of the fabric `wires and pressing upon and locking the wires at such intersections,substantially as described. i

2. The combination with the woven wire fabric, ofa border coil made up ofk a series of coils of wire,said coil containing so many wires as to fill thefspaces betweenithe inter sections of the fabric wires andnpress upon and lock said ywires at such intersections, and said coil covering the ends of said fabric wires, substantially as described.

The combination of the fabric composed of the interwoven transverse and longitudinal coils of wire with a border coil confined Within the spaces between the intersections of the fabric coils at the edge of the fabric,

t said border coil iillingsaid spaces and locking the ends of the fabric coils and said ends extending within and being covered by said border coil, substantially as described.

4. The combination with the fabric composed of interwoven transverse and longitudinal coils of wire, of a border coil confined within the spaces between the intersections of the fabric coilsat the edge of the fabric and filling said spaces and said fabric coils being coiled in one direction and` `the .border coil4 being a coil of theiopposite hand or direction, substantiallyastdescribcd. y

Intestimony whereof Ihave. hereunto set my hand this 28th day of October, 1893.
