After the Great pressure is an acute angle I2 is a binding the edges of the metal lath binding I2 has placed over the edge of the then applied to the U-shaped binding l2. This great pressure clamps or binds the binding material I2 on the expanded metal ll. As the pressure is applied to the U-shaped binding forcing the two legs of the'binding closer together the expanded metal '5 is somewhat flattened. This flattening of the expanded metal causes the sharp edges l3 to dig in or'cutin the binding 12. Fig. 2 shows how the grooves I 4' have been cut in the binding ma terial by the edges 43.

Any tendency for the binding material l2 to spring apart is counteracted by the tendency of the compressed expanded metal H to return to its original position. After the binding is clamped to the expanded metal or metal lath 5 it is practically impossible to remove the binding. Any force tending to remove the binding from the expanded metal causes the points of the expanded metal to grip or dig in. the notches or grooves l4 more firmly. Thus it will be noted that the greater the force exerted on the binding tending to remove it the greater the resistance.

Figs. 3 and 4 show a modification of our invention. The binding l2 has an integral portion l5 extending at right angles to the plane of the expanded metal. This extended portion l5 has various uses. It adds strength to the binding. In connection with the floor mat shown in Figs. 3 and 4.- it may be used for a foot scraper in addition to the sharp edges l3 of the metal lath ll.

Fig. 5 shows a fire screen embodying our invention. Several pieces of expanded metal are bound in accordance with our novel idea, as shown in Fig. 2. These pieces are hinged together by means of rings IS. The unit may be finished in various ways and various decorations added to make it attractive.

Fig. 6 shows how the ends of the binding may protrude beyond the end of the expanded metal. The unit shown in Fig. 6 makes an ideal screen door protector. The protruding ends of the bindingare used to fasten the unit to the frame of the screen door.

While we have described several embodiments 4.5 of our invention, we do not wish to be limited to the particular forms shown and described as it will be apparent that many modifications therein may be made without departing from the scope of our invention as set forth in the appended claims.

Having thus described our invention, what we claim is:

1. In combination, a sheet of expanded metal lath and a U-shaped binding, said binding being fastened to said expanded metal lath by means of pressure, whereby the sharp edges of the flat portion of said metal lath, which form an acute angle with the plane of said expanded metal lath cut into said binding.

2. In combination, a sheet of expanded metal lath, a substantially U-shaped binding, and the opposite side portions of said U-shaped binding pressed so that the sharp edges of said expanded metal lath are substantially embedded in said binding.

3. In combination a sheet of metal lath, a substantially U-shaped binding, and the opposite side portions of said U-shaped. binding pressed so that the sharp edges of said metal lath are substantially embedded in said binding whereby a force tending to pull said binding from said metal lath will tend to cause the sharp edges to cut deeper into the binding.

4. In combination a sheet of expanded metal lath and a frame comprising sideand end bars each composed of a plate folded longitudinally substantially midway between the longitudinal edges thereof and the opposite side portions of the foldv pressed so that the sharp edges of said expanded metal lath are substantially embedded in said binding.

5. In combination a sheet of expanded metal lath and a frame comprising side and end bars, each composed of a plate folded longitudinally substantially midway between the longitudinal edges thereof and the opposite side portions of the fold pressed so that the sharp edges of said expanded metal lath are substantially embedded in said binding, whereby said sharp edges tend to cut deeper into said frame when a force tends to pull said frame from said expanded metal lath.

6. In combination a sheet of expanded metal lath, a U-shaped binding, said binding being fastened to said expanded metal lath by means of pressure, whereby the edges of the flat portions of said expanded metal lath which form an acute angle with the plane of said expanded metal lath, cut into said binding in such a manner that a force tending to pull said binding from said expanded metal lath will tend to twist said flat portions in such a manner that they tend to cut deeper into said bin-ding thus holding the binding more securely.

7. In combination a sheet of expanded metal lath and a substantially U-shaped binding therefore, said binding being uniformly pressed over the edges of said expanded metal lath, whereby all the sharp edges of said expanded metal lath which come in contact with the binding are substantially embedded therein.
