WIRE FABRIC FOR BEDSPRINGS AND OTHER ARTICLES Filed May 9, 1935 INVENTOR.

Patented June 1 6, 1936 WIRE FABRIC FOR BEDSPRINGS AND OTHER ARTICLES The invention relates to wire fabrics and has for its main object to provide a fabric of extremely simple and inexpensive construction which is made from two simple elements, can be built up to various sizes, and assembled with a minimum expenditure of time and labor.

Another object is to provide a wire fabric in which the whole upper surface is practically even with no upwardly-protruding members. A further object is to provide a wire fabric in which any weight which is placed thereon is distributed to all the members. A still further object is to provide a wire fabric which may be used for many purposes in the upholstery art.

These and various other objects and advantages will be readily understood from the following description and from the accompanying drawing of preferred embodiments of the invention, in which, however, modifications may be made without departing from the scope of the appended claims. In the drawing Fig. 1 is a fragmental plan view of the fabric shown attached to the end members of a bed spring frame,

Fig. 2 is a partial side view of Fig. 1,

Fig. 3 is a fragmental plan view showing a certain modification, and

Fig. 4 is a side view of one of the members shown in Fig. 3.

Referring now to Figs. 1 and 2, the fabric consists of a plurality of links l0, and a plurality of straps H which are formed of wires bent back and forth to form a zig-zag. The links l0 are U-shaped and the closed ends are twisted, as

' plainly shown at [2, while hooks 13 are formed on the free ends. The openings M in these hooks are of suificient size to allow the strap H to pass freely through them. The zig-zag straps may either be made with an open formation, as shown at H, or with each bend substantially closed, as shown at HA.

The fabric is assembled by passing a strap ll through the hooks in the links Ill and then pulling the links into the bends of the strips, as plainly shown in Fig. 1. The next row of links is added by inserting one of the legs of each hook between the legs of the hooks already assembled and then pulling the hook down until its closed end engages in one of the loops in the strap II. The lower row of links have their legs forced together and hooks I5, formed on a plurality of end zig-zag straps, are engaged in the hooks I3 of the links. Hooks l6 are formed in the other end of these straps and these hooks are engaged directly in holes in the frame member ll of a bed spring. Similar end straps are provided with hooks l8 which engage in the closed ends of the upper row of links, while hooks I9 are formed in the other end of these straps and engage in holes formed in the frame member 20 of the bed spring. These end straps act in a similar manner to ordinary tension springs, but have the added advantage of being flat so as not to cause wear to the padding or bedding placed on top of the fabric.

In the modification shown in Figs. 3 and 4, the closed end 21 of the link Ill is not oifset but an offset 22 is formed in a zig-zag strap II as plainly shown.

From the foregoing it will be seen that this fabric consists of only two elements, namely the hooks in and the zig-zag straps II. This construction makes it possible to manufacture the parts at a very low cost and makes it possible to assemble the fabric very rapidly and with the simplest of tools.

Having thus described the invention and its objects, what I claim is new and wish to protect by Letters Patent is:

1. A wire fabric of the class described comprising a plurality of straps each formed of a wire bent back and forth in alternate direction to form a zig-zag; a plurality of U-shaped links having hooks formed at their open ends; and the hooks of the links engaged in the bends of one side of the straps and the closed ends engaged in the bends on the other side of the straps.

2. A wire fabric of the class described comprising a plurality of straps each formed of a wire bent back and forth in alternate direction to form a zig-zag; a plurality of U-shaped links having hooks formed at their open ends; the hooks of the links engaged in the bends of one side of the straps and the closed ends engaged in the bends on the other side of the straps; and a twist imparted to the closed ends of the links to cause all the straps and all the links to lay in substantially the same plane.

3. A wire fabric of the class described comprising a plurality of straps each formed of a wire bent back and forth in alternate direction to form a zig-zag; a plurality of U-shaped links having closed hooks formed at their open ends; the openings in the hooks being of such size as to enable the straps to be passed through them; the hooks of the links engaged in the bends of one side of the straps and the closed ends engaged in the bends on the other side of the straps; and a twist imparted to the closed ends of the links to cause all the straps and all the links to lay in substantially the same plane.

4. A Wire fabric of the class described comprising a plurality of straps each formed of a wire bent back an Iorth in alternate direction to form a zig-zag; a plurality of U-shaped links having closed hooks formed at their open ends; the openings in the hooks being of such size as to enable the straps to be passed through them; the

hooks of the links engaged in the bends of one side of the straps and the closed ends engaged in the bends on the other side of the strap; and a twist imparted to the bends in the straps in which the closed ends of the links are engaged to cause all the straps and all the links to lay in substantially the same plane.
