0F I-IOLLYDALE, CALIFORNIA TILE BOARD Application filed April 7, 1930. Serial No. 442,114.

This invention relates to tile board, and has for its object the provision of an improved method and means for forming and mounting tile blocks on suitable sheets of stiff material such as ply wood, plaster board, and the like.

It is an object of this invention to provide a tile board formed of a stiff and substantially non-expansible back having one surface of said back covered with wire mesh,

screen, metal lath, or the like, to which is distort, warp, expand or contract the assembled board will be offset or compensated for by the interposition of the carrying material between the back and the tile facing.

In the accompanying drawing I have shown a preferred embodiment of my invenn tion in which the figure is a. perspective view of a section of tile board embodying my improvements.

In said drawing a suitable back 1 is provided, which may be formed of a plurality of plies 2, 3 and 4 of wood,which are arranged with the grain of alternate sheets at right angles to the grain of the other sheets. Such a backing is substantially non-eXpansible. In lieu of the wood back l I may use plaster board or composition lath or any other suitable and sutliciently non-expansible material.

To a face of the back 1 I apply a metallic cushioning member 5 which may be formed of wire mesh afiXedvto the back l by means of staples 6, or by other suitable means. In lieu of the wire rmesh I may employ perfo; rated material, expanded metal lath, or any other suitable light weight material. The wire mesh, however, is deemed to be most suitable for the purposes ofy my invention.

The member 5 forms a carrier and atthe same time a cushion for the facing of tile, and is adapted to be covered bya coating of a semiplastic cement 7 which fills the interstices between the wires of the mesh and underlies certain portions of the mesh, thus forming a smooth adhesive coat outwardly lof the wire mesh 5. An example of said semiplastic cement 7 may comprise a-composition of asphaltum, sal soda, marble dust and water. To this coat a facing 8 of tile lis applied by pressure or otherwise. The blocks of tile 8 are pointed as at 9 in the usualqmanner and by the usual means, and the arrangement of the tile blocks is such as to produce ornamental and decorative effects.

It will be observed that the coating of cement 7 and the eXpansible wire mesh5 form an expansible cushion between the substantially stiff and non-expansible lback ll and the facing of tile8, so that any tendency to warp, distort, expand or contract is compensated for by the intermediate cushion, thus reventing damage to the tile facing. I pre er to use a cement which may combine certain vegetable and mineral ingredients in such manner that a maximum tenacity and a suHcient resiliency will be provided, and which will at the same time provide against the entrance of moisture and bacteria. By semi-plastic cement is meant a composition which when set and dry will not be brittle, but will retain a substantial amount of resiliency so as to compensate for the expansion and contraction of the mesh carrier 5. For instance, assuming that the back l is non-eXpansible, it is apparent that the wire mesh 5 is highly eX- pansible due to differences of temperature. The coating 7 should be sufficiently resilient tol compensate for the expansion of the Wire mesh 5 without cracking or pulling the tile blocks 8 apart.

It Will be observed that I have provided a substantially economical method and means for producing tile board in sheets or panels of suitable size whereby the erection of the same in a building may be quickly and economically done as compared to other methods.

Vhile ply Wood or composition panels, as at l, are substantially stif and proof against warping and distortion, I may provide any suitable means on the backs of said panel for additionally stiifening the same, as taught by others in the art.

What I claim is:

1. A Wall structure comprising a panel l formed of a non-expansible back, an eXpansible metallic sheet of material applied to a face thereof, a semi-plastic cement applied oversaid metallic sheet and a facing of tile attached to said cement.

2. A Wall structure comprising a panel formed of a stiff back, a sheet of Wire mesh attached to a surface of said back, a semiplastic cement applied over said Wire mesh and a tile facing attached to said cement.

3. A structure formed of separate panels having non-expansible backs, sheets of apertured metallicmaterial attached to the surfaces of said backs, a coating of semi-plastic cement applied over said metallic material and tile facings attached to said cement. p

4. A structure comprising a panel formed of a stiff back, an eXpansible metallic cushion attachedv to a surface of said back, a semiplastic cement applied over said cushion and a tile facing adhesively applied to said cement.l

5. 4A. structure comprising a panel formed of a non-expansible back, an eXpansible metallic cushion attached to a surface of said back, a semi-plastic cement covering said back and said cushion, and a tile facing covering said cement.
