Acoustical tile and the like are applied to a surface, following the herein described means and method, by attaching parallel channel members to a surface to be covered or to the studding or other base construction members which lie under the tile, applying to such channels acoutical tiles which span the spaces between parallel channels, and fastening the tileain place by means of clips, which on the one hand, have points that are forced into the bodies of the tile at the vertical edges thereof and on the other hand have bases which slide in and are supported by the channels.

In the embodiment of the invention chosen for illustration, and for illustration only, the base supporting members for the channels are wooden members 50 which may be joists or other parts of the permanent structure of a building. Channels I I are fastened across such joists, usually at right angles to them, by any suitable means, such as screws extending through holes in the bottoms of the channels. The channels H are parallel and from longitudinal center to longitudinal center are equal to the width of the tile to be suspended. The channels H are formed of metal, and have flanges comprising normally disposed and inturned sections, the inturned sections Ha defining a space between them less wide than the space between the normally disposed sections.

Clips I2 are of sheet metal. Each has a T shaped base IS. The width and height of the cross bar of the T is approximately the size and shape of the open cross section between the bottom, normally disposed sections and inturned sections Ila of the channels H. The bases [3 fit closely in the channels without binding.

From the base I3 in the four prong clip I 2, as shown in Figures 4 and 8, there extends a Y or V shaped Web I4 which, in the finished ceiling, lies between the vertical edges of contiguous tiles. From each of the two arms of the Y or V shaped web l4, extend two prongs l5 and I6. Each clip l2, therefore, comprises two pairs of prongs, two prongs being one hundred and eighty degrees from the other two, one pair being an inside pair, and the other pair being an outside pair.

Acoustical tile material usually consists of comparatively soft and yielding material, generally fibrous. Such material is pressed into the form of tiles I! or the like, of suitable thickness, and of predetermined length and breadth, with a binder holding the material together and preventing the ready breakage of the tile. The tiles are square or of some other shape such that they may be laid edge to edge to form a continuous flat surface. The tiles I! are placed over the channels II, which are fastened to the members I0. It has been found suitable, as previously 'stated, to space the channels ll apart, center to center, the width of the tile that is used therewith. The tiles I! are placed on the channels II with the edges of adjacent rows of tiles I! meeting over the centers of the channels H.

The bases it of the clips l2 are positioned within the channels H, either from the ends of the channels or by inserting the base I; into the channel lengthwise and then turning the clip until the base is across the channel withits ends locking under the inturned flanges Ha of the channels H. A channel H with flanges ila removed and with the clips l2 transversely thereof is shown at the rightof Figure 3.

The general procedure is to move the clip I2 along the channel 'll until the prongs, either i6 or ii, contact the tile. The prongs are then driven into the edge of the tile by a hammer or axe or by a block of wood and mallet. Generally but little force will be needed as the prongs are sharp and the tile is soft.

The first row of tiles i1 is generally laid against an abutment, blocks or a vertical wall. The channels H run to proximity or into contact with such wall.Clips 12 are seated at the ends of the channels. These clips l2 have one pair of wings H or iii) turned up by the tile setter as in Figure 5. Such bending may be done with a hammer or pliers. The other pair of wings project away from the wall and a tile I1 is secured thereon by having the tile driven onto the prongs by tapping the tile with hammer or mallet. This secures one edge of tile. The opposite edge is secured by driving home clips l2 in the manner described.

The second row of tiles is then secured in suspension on the channels by laying the tile against the second series of clips l2. The edge of each tile in such second row is forced against the outstanding prongs of the second laid series of clips. The tiles are forced home on to the second series of prongs by placing a board on the opposed edge of the tile and tapping the board with a hammer. The outer edge of the second row of tiles is secured by driving into it a clip in the manner already described. These several steps are'repeated until the surface is covered.

In some operations, the tile may be driven against one series of clips while the next succeeding series of clips is being driven into it.

It the tiles are placed to meet at the centers of the channels II, it is clear that each clip will be at the juncture of four tiles, as indicated at I! in Figure 3, and will have one prong in each tile. The four tiles will thus be fastened firmly together more or less as a unit. As the fastening is repeated on each corner of each tile, the entire wall covering is in effect a single unit firmly bound to the subjacent supporting structure through the medium of the clip bases in channels attached to the structure.

The channels H at the edge of the ceiling will rest against the side walls or be spaced therefrom and will not have centers coincident with the edge of the tile. If set in sufliciently, clips It may be used with such channels or if close to the wall, clips like those shown in Figure 7 may be employed.

abut against another surface parallel to the long axes of the channels, or the tile covering is to end on a line parallel with the axes of the channels, or an approximation thereof, the side wall channel Hb, must be spaced away from the ending line of the tile as shown in Figure 2, if clip H2 is employed. The modified clip I I2 of Figure 7 may be used with the channel against the wall it employed with its web pointed inwardly but requires an inset channel if used with its web Where as in the first case above, the tiles pointing outwardly. Clip H2 is applied in the same way as the clip I2 wi'h the prongs penetrating the tile adjacent the edge engaging the side wall.

The clip illustrated in Figure '1 has a base HI identical with base is of the clip shown in Figure 4. It comprises a web H4 which resembles onehalf of the Y or V shaped web of clip I2. The web H4 extends to one side of. a channel and does not bridge such channel as does the web ll of clip l2. Clip H2 has two prongs H5 and H6,

one pointing forwardly andrthe other rearwardly.

The laying of tile at one' side wall has already been described. The tile. laid at the other side wall may be laid in a similar manner, 1. e., with the channel wholly under the tile and not half under it. The clip l2 shown in Figure 4 may be used in the final channel or preferably the clip H2 in Figure 7 may be used.

When the terminal row of tiles I1 is at right angles to the axes of the channels H, clips l2 and H2 may be used as elsewhere if there is room for their insertion, only one of the prongs I 5 or H5 on one side of each clip being used. The other prong H6 or prongs l6 may be bent out of the way to provide more room. When clips I! or H2 are used, the edges of the tiles are blocked up or secured against movement along the channels ll.

When the prongs IE or ii and H5 or H6 on either side of clips are folded over against the V shaped web I, or the half V shaped web H4, they will not protrude appreciably from the surface of the web and the clip may be placed close to another wall, holding only one side of a tile, as indicated at IS in Figure 3.

The clip H2, shown in Figure '7, is used when it is desired to lay the tile staggeredly rather than have them in alignment at all edges. Staggeredly arranged tiles are shown in Figure 6. When the clips H2 are positioned, the web H4 extends wholly to one side of the center of the channel as shown at 20. This is true when the clip is reversed as shown at 2|. Each tile is thus supported by four clips H2, two at one side and reversed, and two others at the opposite side and in reversed position. The first and last rows of clips may be laid with clips H2 with one wing folded against the web as shown in Figure 8. The channels at the side walls need not be inset from thewall but may rest against the side walls. If extreme corner support is desired for the tile at the side wall, the channel is inset as shown at the left of Figures 2 and 3 and clips H2 with webs H4 pointing outwardly are employed.

It is sometimes necessary and at other times desirable to nail the wall abutting edge of the last row of tiles laid transversely of the channels. The tile, if it fits snugly against the wall at its edge, does not lend itself readily to support by either form of clip. It is diificult to get the clips into position. The usual procedure is to nail such last row of tile at its outer edge. The nails provide a stop to prevent movement of the tile longitudinally of the channels. If clips l2 or H2 are used, it is necessary to block the tile against such movement by nails or wooden plugs or otherwise.

Numerous modifications of the clips may readily be made without departing in any way from the spirit of the invention.
