SPECIFICATION forming part of Letters Patent No. 621,851, dated March 28, 1899.

Application filed December 27,1897. Serial No. 663,755. (No model.)

To aZZ whom it may concern:

Be it known that I, STANISLAS ROSENBERG, a citizen of the Republic of France, and a resident of 14 Rue Singer, Paris, France, have invented certain new and useful Improvements in Decorative Plates, Tiles, &c., of which the following is aspecification.

The present invention relates to improved plates, tiles, and other wall or ceiling coverings which are designed to replace the tiles hitherto used in decorating and which owing to their plane and v enameled surfaces produce cold, shining, and glaringly-lustrous effects. Y

Myinvention consists in the production of relief designs in connection with plates, tiles, dcc. said designs composed of projecting and transparent semispheres of glass, &c., which break the ordinary plane surface and by substitutin g an irregular reflecting-surface break up the glaringly-luminous rays.

In order that my said invention may be particularly described and ascertained, reference is hereby made to the accompanying drawings, in which similar letters of reference indicate corresponding parts and by the aid of which the process of manufacture will be readily understood.

Figure 1 is a section of a matrix. Fig. 2 illustrates a suitable tool; Fig. 3, a section illustratingthe method of forming a tile, and Fig. 4 an example of a design produced on a tile.

A layer or plate'of plaster-of-paris A serves as a matrix and is shown in section in Fig. 1. The outlines of the designs required to be produced are transferred by known means onto this plate, and by means of bodkins or tools B with rounded points, Fig. 2, small cavities are formed having the shape of a spherical segment equal to about one-third of a sphere. By providing tools of various sizes cavities of different sizes, a a, can obviously be formed. hen the number of cavities required by the design have been formed, the surface of the matrix A is besmeared with suitable fat or grease, such as Vaseline and the like, and in each cavity is placed a small colored transparent glass ball or bead c c, Fig. 3, corresponding to the colors of the design required to be reproduced. The balls or beads are covered with cement O of corresponding colorthat is to say, if, for instance, a green leaf is required to be reproduced green beads are used and the interwalls between them are filled with green cement, which thus incloses approximately twothirds of the spherical surface of the beads, as shown in section in Fig. 3. This operation having been concluded, cement or plaster-ofparis is cast thereon in the form of an upper layer D in order to impart to the whole covering sufficient strength and consistence. The whole is then allowed to dry. The plate is afterward detached, the Work being completed and assuming the appearance shown by Way of example in Fig. 4.

The balls or beads are transparent and 0011- sist of glass, and they may cover the whole or only a part of the plate, tile, or covering.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. An improvement in the art of making decorative plates which consists in forming depressions in a suitable design-plate, then placing balls orbeads of colored glass in said depressions, then spreading a layer of cement over said plate and balls and finally removing said plate from the hardened cement and balls, substantially as described.

2. An improvement in the art of making decorative plates which consists in forming depressions in a plastic design-plate, then smearing the depressions with grease, then placing balls or beads of colored glass in said depressions, then spreading a layerof cement of the same color as said balls over said plates and balls, then spreading a renforcing-layer of plastic material over said cement, and finally removing said plate from the hardened cement and balls, substantially as described.

3. An improvement in the art of making decorative plates which consists in providing a suitable design-plate with depressions therein, then placing balls or beads of colored glass in said depressions, then spreading a once of two witnesses, this 11th day of Delayer of cement over said plate and balls and IOGIDIJBI', A. D. 1897.

finally removim said plate from the hardened 7 T cement and balTs which adhere thereto, sub- STANISLAS ROSEN LERG' 5 stantially as described. \Vitnesses:

In testimony that I claim the foregoing as I EDWARD P. MAOLEAN,

myinventionI have signed my name, in pres- 1 PHILIPPE OARDENT DE SERGNIAL.
