WALL COVERING Filed Aug, 5. 1929 [Him 6 INVENTQ Patented Apr. 7, 1931 PATENT OFFICE HERMAN I-I. HUMMERT, OF SAN ANTONIO, TEXAS WALL COVERING Application filed August 5, 1929. Serial No. 383,566.

This invention relates to Wall coverings of the type which are particularly adapted to receive a plaster coat or similar plastic surface; and among other objects, aims to provide a covering in sheet form which may be rolled up, like manufactured roofing, which may be tacked in place, like fly netting, and which will not shrink and cause the plaster coating to crack. Further objects of the invention are to provide a very economical and easily manufactured wall covering of this character. I

In the accompanying drawings illustrating an embodiment of the invention,

Fig. l is a fragmentary elevation of the Wall covering shown tacked to a wall, the several layers of the covering and the final finishing coat, being indicated;

Fig. 2 is a longitudinal section through the improved wall covering;

Fig. 3 is a greatly enlarged section; and

Fig. i is a section on line 4e-4t of Fig. 3, to the same scale as the latter figure.

As is well known, wooden laths are not at all satisfactory supports for plaster, because of the virtual certainty of shrinkage with consequent cracking of the plaster. Metallic laths are better, but are rather expensive. The present invention seeks to provide an inexpensive wall covering which provides a satisiactory foundation for plaster and the like.

In accordance with the invention, a sheet of commercial wire netting, commonly called fly screening, is sent through a machine having corrugated rolls, to provide a corrugated reticulate wire sheet 5. Such a sheet may be tacked directly to the Wall boards such as ship-lap 6 and the plaster then applied; but preferably the corrrugated wire netting is first united with a paper backing 7 by means of a strong glue 8. The paper sheet should be of some thin, tough paper such as heavy jute Wrapping paper; and the glue should be applied so as to cover the depressions in the wire netting, leaving a series of projecting ridges 9, (Fig. 3) forming keys for holding the plaster 10. The keys should extend horizontally or transversely relative to the length of the sheet of Wall covering, so as to provide a maximum support for the plaster until the latter has had time to harden. The completed sheet is secured by tacks ll to the wall.

As both paper and wire netting are quite flexible the sheet may be rolled up and shipped and handled in rolls. When the covering is applied, it may be secured at the top, adjacent the ceiling, by several nails and tacks, and the workman may then tack the remainder of the sheet to the Wall.

Instead of glue, or in combination with the glue, thin wire staples may be used to secure the paper sheet and wire netting together.

Obviously, the invention may assume se veral different forms.

What I claim isz- A thin flexible wall covering particularly adapted to receive plaster or the like comprising, in combination, a sheet of tough thin paper; a sheet of commercial Wire netting of the type employed for screening windows against insects, said Wire netting having corrugations providing keys for holding a thin layer of plaster; and means securing the wire netting to the paper sheet.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

HERMAN H. HUMMERT.
