BUlLDlNG PLATE OR TILE.

SPECIFICATION forming part of Letters Patent No. 552,939, dated January l l, 1896.

Application filed June 13, 1895. Serial No. 552,6 98. (No model.)

To all whom may concern.-

Be it known that we, KARL 'WAHL and J- HANN RIXY, subjects of the Emperor of Austria-Hungary, residing at Prague-Smichew, Bohemia, Empire of Austria-IIungary, have invented certain new and useful Improvements in Building Plates or Tiles, of which the following is a specification.

The object of the present invention is a plate made of clay, plaster-of-pa-ris, cement, terra-cotta, or similar material, whichis especially appropriate for blending the fronts and walls of buildings. It may be also decorated on its outside surface, so as to be used for making cornices, stucco-work, (be. This new plate is shown in the accompanying drawings, in which Figure l is a perspective view of a plate for fronts. Fig. 2 is a perspective view of a plate intended for blending smooth walls. Fig. 3 is an under side view of the plate, Fig. 1. Fig. 4: shows several plates united for front walls. Fig. 5 shows several. plates united for other walls. Fig. 6 is a cross-section 011 line a: a, Fig. 5%.

The inside A and the outside 13 of the plate are of the same size, but they are shifted against each other in such a way that ofiset-s CL and Z2 are formed. By this shifting of the outer surfaces against each other we obtain in the simplest way that the joints of the upper and lower faces are not below each other, but, on the contrary, come considerably apart, and that the passing of moisture is thus absolutely prevented, as the individual plates overlap, when the blending of a wall is effected, Fig. (5. v

The insides of the plates are provided with grooves c to increase the adhesion of the cement or mortar and to produce a better binding on the walls. Besides these grooves c longitudinal and cross grooves (Z and e are provided on the inside of the plates, so that in case of need the plates can easily be separated in halves, quarters, and eighths. These grooves on the inside aretherefore so disposed on the plate that the outside surface can be divided in halves, &c., as stated. In order to enable the workman to cover also wooden walls or frame houses with these plates, holes f are provided, through which screws can be passed.

A groove g is provided for the object to receive a wire, in order to effect a solid-combination of the plates.

It is a great advantage of the plates for front walls that the placing upon the walls in accurate distances can be cii'ected very easily and quickly when bars h are made to project from the surfaces of the offsets a and I). These bars are so placed upon the offset 1) that the plates, when secured side by side, abut with their edges 2' against said bars, and that then the joints at the vertical edges fall exactly in the middle below the outside surface of the adjacent plate above. Thus quick work is possible to cover a wall, and also the greatest accuracy in the work is obtainable, whereby the outer appearance of a wall lined with these plates is highly improved.

These plates may also be employed for covering walls inside of buildings, kitchens,bathrooms, halls, &c., where, by dispensing with the bar h, the plates close completely together with their edges. This is of special advantage for walls inside of buildings which are damp, for the plates form with their closed joints an impermeable lining, as each joint is covered by the overlap of the adjoining plate, so that the passage of moisture and also the displacement of the plates are utterly impossible. This advantage cannot be obtained with the ordinary plates now in use.

These plates, as already stated, can also be employed with best advantage in frame houses, where the ordinary plates could not be used. In this case the plates are secured on the wall by means of screws and the joints are filled with cement or plaster. By this means the wall obtains an appearance equal to that of brickwork covered with mortar, and houses can be cheaply erected in elegant and durable style.

The output of cost for a frame house with these plates being about half the cost only of a brick building shows how great an advantage is oifered by these plates over the ordinary plates of known style.

Buildings erected with these plates admit also of a very effective ventilation of the walls and are fireproof in every respect.

The plates may be used also directly as material to erectwalls and offer the same advantages as walls of stone, brick, and other n1aplacement of the individual plates, and l1av-- ing the spacing bars h, substantially as described.

2. Facing plates of plastenclay, cement, terra-eotta or similar material with inside and outside surfaces A, B of equal size, being shifted against each other and forming offsets (a I) so as to overlap the joints, provided with grooves g for Wires and holes fin line with said grooves, as described.

3. Facing plates of plaster, cement, clay, terra-cottaor similar material with inside and outside surfaces A,I of equalsize, being shifted against each other and forming offsets a Z) so as to overlap the joints, provided with grooves 61 6, provided Withgrooves g and screw holes f and provided with bars 7L substantially as and for the purposes setforrh.

In Witness whereof We have hereunto set our hands in presence of two Witnesses.
