20 Claims.

This invention relates to fastening devices in building constructions and has reference more particularly to a method of reenforcing acoustical tiles and securing them in place;

Acoustical tiles are generally made of a has of mineral wool with a suitable binder, or of other light weight fibrous material of a frangible nature. Such tiles are frequently fastened in place by means of an adhesive material applied to the exterior rear surface of the tile. This method of fastening when used alone has proved unsatisfactory for tiles subject to expansion and contraction, since the adhesive easily becomes loosened and allows the edges of the tile to curl m away from the wall or ceiling surface. In some constructions acoustical tiles are nailed to the building surface. Due to the composite nature of such tiles, the nailed. edges frequently become turn or otherwise weakened and pull away from the nails.

An object of this invention, therefore, is to provide a satisfactow mechanical attaching means for securing acoustical tiles or other tiles of a frangible nature to wall or ceiling surfaces.

Another object of this invention is to provide a reenforcing means for the edges of disintegrant fibrous tiles.

A further object of the invention is to provide acombined reenforcement and fastening means for securing tile to a wall or ceiling surface, also to. improve buildingconstructions in other respects hereinafter specified and claimed.

Reference is to be had to the drawing forming a. part of this specification, in which 3 Fig. 1'. is a perspective view of a tile having the reenforcing and fasteningmeans in place,

ularly disclosed in the patent to King and Stitt,

. No. 1,769,519 of July 1, 1930.

A wedge-shaped, metallic reenforcing and fastening member 8 shown in Fig. 4, is composed of of said reenforcing member.

The acoustical tiles 6, or other tiles of a similar These a thin sheet of tin-plated steel, or other suitable metal, having an integral double folded edge '9 which furnishes strengthening means lengthwise Ribs 10, preferably two or more in number, are formed integrally the reenforcing member 8, extending perpendicularly to the folded edge 9 and cutting edge 11, and serve to laterally strengthen said reenforcin member.

The cutting edge 11 of reenforcing member 8 is M pressed or driven into the edges 12 of tile 6, preferably centrally between and parallel to the back and front faces of said tile. Pressure of the hands or a hammer blow applied to the folded edge 9 is sufficient to force the reenforcing memher 8 into the edge 12 of a tile 6 in such a manner that the reenforcing means 8- is embedded in the tile 6 and the folded edge 9 of reenforcing member 8 is flush with the edge 12 of said tile. These reenforcing members are impressed at suitable intervals on the edges 12 of tiles 6.

The exterior rear surface 1 1- of tile 6 is then placed against the wall surface 15 of wall 15a, or, if desired, a layer of adhesive 16 may be interposed between said tile surface 14 and said wall W surface. 15 to hold the tile in place during and after the fastening operation. Nails 1'? are then driven into the tile 6 through the front surface 13 and extend through thereenforcing member 8 at the point 18, being countersunk to such a depth M that the heads 19 of said nails rest firmly against the reenforcing members 8 and the point 20 of said nail extends into the wall 15a and thus holds the tile 6 securely against the wall surface 15. As

shown in Fig. 3, the nails 17 are preferably driven into tile 6 at an angle to the surface 13 to more firmly hold the tile in place against the downward pull of gravity and to insure that the tiles are firmly crowded together'in close edge-abutting. relation. Insertion of the nails at a fairly sharp angle is of particular advantage where the tiles are attached against a plastered surface, since the nails .thus provide a substantially hook-like engagement for the tiles, whereas if they are driven perpendicularly into the plaster they become readily dislodged due to the poor holding qualities of the plaster. The openings left in the exterior face 13 of the tile by the insertion of nails 17 and the countersinking of nail heads 19 may be filled with a suitable material, but are preferably left 1 open, since acoustical tiles are ofnecessity of an extremely porous nature and additional openings in the exteriorface merely serve to further increase the sound absorption qualtities of such a tile without disturbing the general appearance. II.

Moreover, since the nails 17 are preferably inserted at a slanting angle, the opening in question will likewise be on a slant, and, as is readily apparent from an inspection of Fig. 3, the nail heads 19 will be substantially hidden from view when the tile covered surface is seen from even a short distance. Fastening members are preferably used on each of the four edges of each tile.

I would state in conclusion that, while the illustrated examples constitute practical embodiments of myinvention, I do not wish to limit myself precisely to these details, since manifestly, the same may be considerably varied without departing from the spirit of my invention as defined in the appended claims.
