structure, and particularly does the inventionrelate to the installation of such units formed of acoustical tiles which, as is known in the art, are formed in various designs, shapes and sizes, composed of bagasse or other fibrous material,

wherein the tiles have marginal bevels on their front faces which, when the tiles are juxtaposed in assembled relation, provide intervening junctional channels or grooves.

In certain instances it has been proposed to assemble and install these tiles as a ceiling or wall structure by nailing the separate tiles into the subjacent supporting wall or ceiling, or into the plaster or into the furring thereon. In other instances installations have been made by gluing the tiles in assembled position on, the sublacent surfaces. In those installations where nails have been used for holding the bagasse tiles in position, the tiles have pulled downwardly with referenee to .the nails into a sagging position or the tiles have fallen completely from the ceiling or wall structure. In other types of installations the glu or adhesive has, in a number of instances, been ineffective to hold the tiles in position and they have sagged or dropped down and it has been necessary to re-tile the entire surfaces, or to re-nail the entire surfaces in order to repair or restore the wall or ceiling to uniformity of appearance and secure assembly.

In the present invention I provide means for assembling a ceiling or wall construction formed of individual units of acoustical tile or of units having other construction, which will securely and omamentally hold the units or tiles in assembled position either as a repair job or as an original installation and I have provided this way to secure a firmly supported unit construction as well as an ornamental one. In addition, the means I have provided also acts to prevent projeetion or breathing at the juncture between the individual tiles making up the installation and, therefore, the objects of the present invention are to provide means for accomplishing the foregoing advantages and results as well as to provide a simple type of supporting means formed of a plurality of standardized shapes adapted to be used in conjunction with standard acoustical tiles or other construction units for permanently installing various combinations and arrangements of the tiles to iit and cover various sizes and shapes of walls or ceilings; another object of the present invention is to provide assembly means for holding acoustical tiles and the like firmly in assembled position with respect to a subjacent wall or ceiling structure in a manner such thata defectiv installation can be remedied without removing any of the tiles from position on the wall structure; to provide means for installing a plurality of straight edge tiles mechanically without the use of adhesive or nails, or to consolidate the present installations which have been put up with adhesive or nails but which are falling down; to Provide a. system for firmly holding in position an installation oi unit tiles or the like wherein a series of holding devices are employed to overlie the marginal meeting surfaces of the units to hold the same in place and in a manner such that the presence of nails, bolts or other similar fastening means is not discemable in the completed installation to provide these and other Fig. 9 is a modification of the installation I shown in Fig. 1 wherein strips only are used for holding the assembly in place.

Referring now to the drawings in detail, it is to be understood that the present invention relates to the installation of standard or nonstandard types of geometrical constructional shapes herein specifically illustrated as an acoustical tile which, in general, is formed of bagasse and which is utilized as a covering for wall or ceiling structures for buildings and the like. The acoustical tiles are generally formed at their margins with beveled surfaces in the manner shown in Figs. 3 and 14 so that when the tiles are juxtaposed in assembled relation a system of V-shaped channels is provided which may be either symmetrically arranged as shown in Fig. 1, or may be in staggered arrangement, as shown in Fig. 11. It is to be understood that any type of shape or any type of tile or construction unit may be utilized if the same are characterized by certain constructional features which are inherently suitable or adaptable for use in connection with the fastening devices forming the subject matter of the present invention.

In general, where I refer herein to acoustical tile, it is to be understood that I am not specifically limited to acoustical tile, but that any type of constructional units may be utilized provided they are adaptable to use in connection with the present invention. In general the acoustical tile is adapted to be assembled to cover a wall or ceiling, adapted to be held firmly in assembled position on the wall or ceiling by means of a series of strips and fastening clips, some of the forms of which are shown in Figs. 4 to 8, inclusive. Modifications of these clips may be utilized for forming further arrangements or assemblies of the acoustical tile.

Because of the nature of the present invention, it is peculiarly adaptable to installations which have been put on with adhesive or have been nailed on and wherein in the first instance the adhesive has crystallized and the tile has become loose, has sagged or fallen down. Since practically all of these acoustical materials are soft and porous in those installations where they have been held in place by nails, the nails have gone clearly through the acoustical tile so that the latter has come down over the heads of the nails and the tiles have fallen down and sagged.

It is to such installations, as well as to new installations, that the present invention is peculiarly adapted. Heretofore there had been no way known of patching up or re-fastening the tiles in position without removing all of the tiles and starting afresh. However, in the present instance, inasmuch asthe fastening means herein disclosed takes advantage of the V-groove formed at the marginal juncture of the variously assembled tiles, and wherein fastening means is utilized in connection with such V-groove which lies at the outer face of the tile when in a central position, whereby through the agency of the fastening means to hold the tile firmly in assembled position, it must be at once apparent that such defective installations can be immediately re-established and firmly re-assembled without removing any of the sagged or loose tiles from-the installation, but that, on the contrary, all of the tiles can be immediately and very quickly firmly re-united in assembled position in an economical, simple and expeditious manner.

Referring now to Fig. 1 of the drawings, I have shown at 2 any type of subjacent supporting means which may comprise rock lath, old plaster or furring strips and upon which the acoustical tile is adapted to be assembled for ornately covering the ceiling or wall support. The acoustical tile or construction units are indicated at 4 as being disposed in square formation with'their marginal edges in juxtaposition and held firmly in such positionby the various types of fastening means shown in Figs. 3 to 8, inclusive. Referring particularly to Figs. 3 to 8, it will be seen that Fig. 4 shows one of the many elongated strip fasteners, which strip fasteners 6 have a re-entrantly bent central portion I which extends longitudinally of the strip. On either side the sheet metal of the strip is provided with inwardly bent fianges I0, the marginal edges 12 of which project inwardly or, as shown in Fig. 4, upwardly. In Figs. 1 and 2 these strips are shown as extending along the sides of the square tiles 4 in position so as to overlie the marginal beveled walls l3 of each tile and, in this position, it will be noted by reference to Fig. 3, the re-entrant portion 8 of each strip 8 lies within the V-shaped channel l3 whereby each strip 6 is automatically positioned with respect to the juncture of two or more adjacent tiles. In Fig. 2 the strip to the left is shown as being one-half the width of the double width strip 6. This is because the particular tile shown in Fig. 2 is positioned at the outermost edge of the installation and therefore its single beveled portion is adapted to be overlaid with a single width of strip 6', whereas to the right hand side of Fig. 2 the double width strip 6 is adapted to overlie the double, or V-shaped channel lying between two adjacent tiles 4, as shown in cross section in Fig. 3 so that the oppositely and outwardly extending wall flanges 10 of the strip shown in Fig. 4 are adapted to be bent reentrantly toward the outer wall of the tile with the edges I2 thereof entering or digging into the front face of the acoustical tile 4 and sealing the junctions along such lines of contact. In this position clips of various construction are utilized for firmly holding the strip or strips in thus assembled position. For instance, at the end, the L-shaped clip I4 is utilized, the detail of which is shown in Fig. 6. This clip is provided with an aperture 16 at the junction of the two arms l8 and 20 which lie at a degree angle, or at right angles to each other, one leg of this right angle clip 14 overlying the strip 6' shown at the top, and the other leg, 20 of the clip overlying another strip 6' shown extending vertically in Fig. 2. The hole or opening it for this clip is adapted to receive a toggle bolt, nail or screw which passes through the clip and through the junction of the beveled edges of the two adjacent acoustical tiles and enters a furring strip or other subjacent support to hold the clip firmly in position and which clip, in turn, is adapted to firmly hold two adjacent strips in position.

At the juncture of the side strip 6 and the center clip 6 I provide an additional T-shaped clip 24. These clips are preferably composed of heavy sheet material. Fig. 5 shows the details of 15 construction of this clip which is composed of threeradially extending arms, the arms 20 being formed of single width, and the man being" formed. double, thwe, arms radlating'irom a center 38 which is pcrforated to a bolt. nail or other fastener. Thus a toggle bolt, screw or I nail is adapted to pass through the opening 88 of this clip, throughthe comer juncture of the two adjacent acoustical tiles and thenceintothe subjacent structure. The single arms of the clips are adapted to overlie a pair ofstrips 8', as shownin Fig. 2, in such a manner that the strips are capable of longitudinal adjustment to take up any variation in size either in the strips or in the size type of'installationwill be seen. In certain m-' ,stances-it i'spreferred to have installations where v width, the re-entrant central portion 52 is adaptthis T-shaped clip firmly in position.-

By reference to Fig. 13. still another modified no nail heads or bolt heads are observable. 7 Therefore, in order to accomplish this I have provided short clips 58 of the cross section shown in Fig.

of the acoustical tile. A nail or other fastener thus holds the ends of two adjacent strips in position. Similar T-shaped clips 24 are utilized 1 for the other junctures of this tile. These T- shaped strips are used at the very border line '15Wll5h bolt or wood screw holes 80. These clips 88 ,are provided at each of the corner intersections running in a single direction only and at the end sections and corner of the room sections.

, some instances where the tile is of a larger proportion than ordinary construction intermediate where a four-armed fastening clip is not neces- At the juncture of four adjacent or contiguous tiles, the clip 25 shown in detail in Fig. 7 is utilized. This clip has a central web or hub 82 provided with a central aperture 34 and from this central web four arms 38 radially extend outwardly, each formed to correspond ith the cross section of the strip 6 except that each one 01' these arms is made of suflicient dimensions so that it will overlie the strip in the manner shown in Fig. 3 in a manner such that the outer edge 88 of each arm 86 is adapted to dig into or make a sealing contact with the surface of the tile on opposite sides of the re-entrant portion 31 of the arm in the manner shown in Fig. 3. By reference to this latter figure, it will be seen that a toggle bolt 48 may be passed through the hole 34 of the center clip whence it can be forced through the material at the corner junction of four of these square tiles and will thence pass through the subjacent supporting means such as rock, lath, furring or old plaster and will be thence held in position, as shown in Fig. 3, so that in this manner four of these strips 8 and 6' will be held firmly in position by means of the L-shaped clip, two

T-shaped clips and one four-armed clip, in the manner shown in the central lower portion of Fig. 4, or, as shown in the central portion of Fig. 4, the central tile will be held in assembled position to the surrounding tiles by means of four double width strips 8 and four-armed clips 25.

The clip shown in Fig. 8 is a modification of the clip shown in Fig. 7 wherein the web portion between the various arms as shown at 42 is rounded; otherwise the clip is the same.

For those installations where ornateness or final appearance of the assembled structural tile wall or ceiling cover is not of utmost importance, the tiles may be held in position, in the manner shown in Fig. 9, by means of continuous, relatively long strips 48 which are provided at spaced points 48 with holes for the reception of nails, toggle bolts, or screws which pass through the junction of the tiles in the manner hereinbefore described to engage the furring or other subjacent support. In this type of construction no cross strips are necessary.

In the installation shown in Fig. 11, the tiles 4 are arranged in staggered formation and in order to provide for this an additional shape or design of clip is utilized, much along the lines of the type of clip shown in Fig. 5, the same being a T-shaped type of clip, except that the. upper portion of the clip is formed as a double width clip 58, in this manner only distinguishing from the clip shown in Fig. 5. By forming this portion 58 as a double clips may be used, as shown in the dotted lines at the bottom of the upper square l in Fig. 13. These clips 58 are provided with free ends substantially S-shaped in cross section, as shown at 82, whereby to form shoulders, 64 hereinafter described. These clips with the fastening means attached thereto are inserted through the juncture of two tile pieces into subjacent supporting means and are thus held permanently in position, after which an intermediate elongated strip 65 identical in function with the strip of Fig. 4, but of the cross section shown in Fig. 14, is installed in association with the clip 58. Each one of these strips 65 comprises an imperforate central web 68, the opposed free ends of which are provided with flanges 68 having free ends adapted to grip in the shoulder 84 of the clip 58, the imperforate part 88 closing the space between the free ends of this clip 58. In addition, corner clips 69 are provided of the construction shown in Fig. 16, the

same comprising a central web portion 12 and two or more arms radially projecting therefrom. In Fig. 16, four such arms are shown. Each arm comprises an outer lmperforate wall portion 14 having opposed, in-turned flanges 18, each formed with a bent-in toe portion 18. The cross sectional dimensions of these leg or arm portions of this clip are of larger dimensions than the corresponding cross section of the strips 65 so that the arms can overlie and snap into the shoulder portion 62 of the clip 58, as shown in Fig. 14. Thus each one of these clips will overlie the space between the elongated strips 65. The outer upper surfaces 82 of these clips make sealing contact with the front face of the tile to prevent breathing at these points.

In all of the various types of installation it will be apparent that these central clips and and clips permit of a longitudinal adjustment of elongated strip members 6 and 65 in the event that there is a variation in the marginal dimensions of a tile or in the longitudinal dimensions of the strips 6 and 65. By reference to Fig. 14 it will be noted that the curved surface 10 of the center clip is adapted to hide a head 84 of the bolt 86.

It will also be noted that in all of these tiles the clip members are provided with the overlying edge portions 38 and 82 which are adapted to make sealing contact with the front face of the tile at the gap between the ends of the elongated strips 6 and 65, respectively, whereby to prevent breathing between the spaces of the adjacent tiles. In other words, the edges II of the strips and the edges 38 of the clips form breathing stops. In short, when the clips are pulled up on the tile the edges- I2 and 38 bite into the tile and form the sealed breathing stop.

It must also be apparent that the various clips and strips are capable of special design for any type of installation to fit any type of geometric configuration desired in the acoustical tiles or other shaped constructional units.

It is to be understood that the type clip shown in Fig. 15 may be made with a number of legs or arms to conform to the type of shape shown in Figs. 4 to 8, inclusive.
