Patented Sept. 1, 1931 UNETD STATES PATENT OFFICE NELSON W. WEBB. F BELLEVILLE, NEW JERSEY, ASSIGNOR TO EASTWOOD WIRE CORPORATION, OF BELLEVILLE, NEW JERSEY, A CORPORATICN OF NEW JERSEY WOVEN-WIRE BELT FOR PAPER-.MAKING MACHINFS Application filed December 12, 1929. Serial No. 413,575.

The present invention relates to woven wire belts, particularly for paper-making machines of the Fourdrinier type. and has for an object to provide an improved seam or jointure between the ends of the length of wire mesh, and whereby a substantially endless belt is produced. It is particularly proposed to secure the ends by welding. braz-- ing or soldering in such manner that the 0 joint will have substantially the same characteristics of porosity, flexibility and strength as the body of the wire mesh.

A further object is to provide a novel end structure for the wire mesh. whereby the 5 joining of the ends may be carried out in a convenient, uniform and economical manner.

Another object is to provide a seam structure which will present an increased wearresisting surface to the suction boxes over a which the belt passes.

ll'ith the above and other objects in view, embodiments of the invention are shown in the accompanying drawings, and these embodiments will be hereinafter more fully de- 5 scribed with reference thereto and the invention will be finally pointed outv in the claims. 7

In the drawings:

Fig. 1 is a plan view of a portion of a p woven wire belt at the seam;

Fig. 2 is a longitudinal sectional view, taken along the line 22 of Fig. 1;

Fig. 3 is a bottom plan view;

Fig. 4 is a top plan view of a modified form'of the invention; and

Fig. 5 is a sectional view, line 55 of Fig. 4.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring particularly to Figs. 1 to 3 of the drawings there is shown, greatly enlarged, a portion of the two ends of the wire cloth which are seamed together to form a belt, the portion. as shown. representing a piece of the belt which in its actual size is. about of an inch in width. The wire cloth consists of warp wires 10 and weftwires 11 of brass, bronze, or other suitable material for the purpose. The end weft taken along the wire at one end of the cloth is removed and the warp wire ends which would normally be above the weft wire are bent downwardly as at 12. so that they are in line with the other warp wire ends, and are preferably curved. as shown, thus presenting a continuous upwardly disposed bearing forming a recess or groove along the edge of the belt. The end weft wire 13 at the other end of the belt is thereupon engaged in the bearing groove formed by the warp ends atthe opposed end. the warp ends of one end being disposed between the warp ends of the other, and in this relation the ends of the belt are brazed, welded or soldered together.

lVhile th'c brazing, welding or soldering may be done in any suitable manner, I preferably provide solder coated end wire 13 inserted in the end of the cloth in subs-titut-ion of a removed end weft wire, and which upon the application of heat will produce solder joints at the points of intersection with the Warp wire ends, this method resulting in a strong, uniform union along the entire width. of the belt, the interstices between the wires being at the same time maintained free of lumpy spots.

The seam 0r jointure according to my invention may be produced with facility, speed, and economy. and will have substantially the same strength. flexibility and po-- rosity as the body of the wire mesh. The warp wire ends underlying the end weft wire provide an increased wear resisting surface so that the seam will not be subject to excessive w ir and breakage through engagement with the suction boxes.

In Figs. 4 and 5 I have illustrated a modified form of the invention. in which the end weft wires are removed at both ends of the belt, the warp ends at one end which would normally be beneath the weft wire being bent, as at ll. so that they are in line with the other warp ends. while the warp ends at the other end which would normally be above thewcft. wire are bent, as at 15, so that they are in line with the other warp ends- One end of the belt is thus provided with an upwardly offset hearing at the under side, while the other end is provided with a downwardly ofi'set bearing at the upper side. These ends are overlapped with the warp wire ends staggered and with a weft wirc'lG engaged with the opposed bearings, and are joined by b 'azing, soldering or welding. The weft wire 16 is preferably solder coated, so that upon the application of heat solder joints will be produced at the points of intersection with the warp wire ends.

I have illustrated and described-preferred and satisfactory embodiments of the invention, but it will be obvious that changes may he made therein within the spirit and scope thereof, as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In a wire cloth belt, a length of woven wire cloth comprising warp and weft wires and having its ends adjacent, all of the warp wire ends at one end of said length of cloth being disposed in line with each other and engaged at one side of a weft wire at the other end of the cloth. and means connecting said warp wire ends to said weft wire.

2. In a wire cloth belt. a length of woven wire cloth comprising warp and weft wires and having its ends adjacent. the warp wire ends at one end of said length of cloth being disposed in line with each other and having a bearing surface disposed upwardly and extending across the width of the belt. said bearing surface being engaged by a weft wire at the other end of the cloth, said warp wire ends being connected to said weft wire by a heat-produced metallic union.

3. In a wire cloth belt, a length of woven wire cloth comprising warp and weft wires and having its ends adjacent, the warp wire ends at one'end'of said length of cloth being disposed in line with each other and having av bearing surface disposed upwardly, the

warp wire ends at the other end being disposed in line with each other and having a bearing surface disposed downwardly, and a weft wire engaged with said bearing surfaces between said warp wire ends and'conneeted thereto by a heat-produced metallic union.

4. In a wire cloth belt, a length of woven wire cloth comprising warp and weft wires and having ts ends adjacent, the warp wire ends at one end of said length of cloth being disposed in line with each other and having a grooved bearing surface disposed upwardly and extending across the width of the belt, said bearing surface being engaged by a weft wire at the other end of the cloth, said warp wire ends being connected to said Weft wire by a heat-produced metallic union.

In a wire cloth belt, a length of woven wire cloth comprising warp and weft wires vember, 1929.
