To all whomt't may concern Be it known that I,'THo P'soN W; Bnao i, a subject of the King of, Great Britain, residing at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements-in Methods or Processes of Producing Mosaics,

f of which the following is a specificatiomreference beinghad to the accompanying drawing, forming a partithereof.

This invention relates to mosaics for orna-- mental. and building purposes and the objects of the invention are to produce such and the labor required to'setthe blocks or or pieces of mosaic work have to be pieces'inthe base or hinder, such labor being performed manually. Manual 'labor is expensive and slow especially where the blocks separately embedded in a base or binder. Moreover, it is diflicult to securely and firmly set the blocks or pieces in the binder or base by hand so that the binder sticks to all thelem; bedded parts of the blocks or pieces, Q

Myinvention overcomes the present difficulties in this'art because time and labor are reduced to the minimum. The blocks or pieces require no preliminary shaping nor any manual placing. Pieces of material, such as marble, for example,if obtainable of approximately the desi'redsizes can be used without any preparation Whatever. Ordinarily, however, in actual manufacture, it

will be foundto bechea'per, as well as actually necessary, to crush the material obtain able in a rock crusher of some suitable kind to approximately the size it is desired to use, and the roughness or irregularities of the surfaces of the blocks or pieces does not matter for reasons to be presently explained.

The gist of my invention consists in moldnn or casting the blocks or pieces, mixed throughoutthebody of a suitable binder, in suitable molds or forms and then cutting or sawing through "the conglomerate mass so .formed to provide the substantially smooth, exposed surface. of'the -1nosaic, which may then be polished, if desired, in any preferred unanner,

Referring to the drawings w pany' this specification and form a part here of, Figure 1. is a diagrammatic illustration, inperspective, of a molded or cast mass of my conglomerate mosaic material showing how such a mass may be sawed into" slabs, for example; Fig. 2 is a perspective view of a part of a slab sawed or cut from a mass such as that shown by Fig. 1, forexample;

the possibilities of adaptation of theinvention; Fig. 4 is a perspective view of a part of a slab out from the mass illustrated by Fig. 3 and Fig. 5.is a perspectiveview of a :mold. l I In the manufacture of my mosaic, marble or other suitable material or materials may 3 be crushed in a stone crusher and the crushed material may thenbe mixed with any suitable binder as, for example, cement. and water, in a concrete mixer. ing batch of conglomerate may then be poured into a suitable form or mold to .setand after it is sufiiciently hardened it may,

to more completely or to completely harden. The next step in the process is to out or saw the molded mass so as to cut into or through both the binder and the pieces of marble, or other. material or materials, embedded there in so as to produce a mosaic surface. Any pitting of the surface caused by'the cutting or sawing'can then be smoothed with cement On the drawings, the reference numeral 1 designates a molded or cast mass of the con glomerate which has been subdivided by saw cuts 2 into slabs 8, The reference numeral 4- designates the binder and 5 the pieces of marble, or other material or materials, embedded in the binder.

The front face of the part of the slab shown by Fig. 2- shows the completed Inosaic;

The binder may be colored in any selected manner and the pieces embedded therein may be of the same or ofdifferent colors.

if desired, be removed from'the form ormold Fig. 3 is a View similar to Fig. 1 illustrating The resultor binding material and the surface polished.

Figured effects may be readily obtained by placing in the mold or form for the mass supplemental forms or molds and filling the supplemental molds with mosaic material ofcontrasting appearance as compared with the body of the mosaic. Preferably this result is accomplished by using thin metal molds or forms, open at the ends, as

shown by Fig. 5 of the drawings, of the cross sectional shape of the figured eflect desired. The form or mold is filled with the mosaic material and. the supplemental forms or molds are filled with contrasting mosaic material and then the supplemental forms or molds are withdrawn before-the;

binder sets so that the different parts of the mass join together to form a single mass.

- If desired the supplemental molds or forms may be left embedded in the mass instead of being withdrawn.

Fig. 3 of the drawings illustrates a mass of mosaicfsimilar to that shown by Fig. 1

except contrasting material has been moldedinthe mass by supplemental molds like that illustrated by Fig. 5 of the drawings. Fig.

4 of'the drawings shows clearly how the contrasting material runs through 'a slab and the mass in the selected figured shape.

By mixing the blocks or pieces with the binder they are thoroughly incorporated and mixed with the binder so that they are firmly cemented in position thereby not only producing a solid mass but also insuring against their being torn out of the binder while the cutter orfsaw is at work on them.

While for simplicity bf illustration I have shown merely masses'of the conglomerate andslabs out therefrom, it should be undercut into the pieces embeddedxin' the binder stood that the. conglomerate may be molded in any form desired and'then so much of.

the surface or surfaces cut or sawed to to produce the mosaic surface desired The mere molding is net suflicient to produce the desired results because sufficient area of embedded pieces would not show as will be "readily understood but the part to be cut or sawed ofl to obtain the desired surface effect will depend on the character of the molded mass and may be little or much and may become waste or not. In the drawings I have illustrated a method of obtaining slabs with little waste.

. The mosaic produced by this method is a very strikingand handsome material which can be used for all ornamental and building 2. The method or process of producing mosaic which consists in mixing pieces of material throughout the body of a binder,

molding the conglomerate mass thus ob-' tained, allowing the mass to harden and then forming a surface by cutting through the binder and the pieces embedded therein.-

3. The method or process of producing ,mosaic which consists in mixing contrasting masses each composed ofpieces of material mixed throughout-the body of a binder, molding the contrasting masses into a design, and forming a surface by cutting through .the binder and the pieces embedded therein in a plane intersecting thedivision between the contrasting masses.
