METHOD OF MANUFACTURING TILES.

SPECIFICATION forming part of Letters Patent No. 666,963, dated January 29, 1901. Application filed October 4, 1900. Serial No. 31,944- (No specimens.)

To all whom it may concern:

Be it known that we, BERNARD JAOQUART, a resident of South River, in the county of Middlesex and State of New Jersey, and JOHN FRANCIS BOORAEM, a resident of the borough of Manhattan, in the city and State of New York, citizens of the United States, have invented a new and useful Improvement in Methods of Manufacturing Tiles, of which the following is a specification.

Our invention relates to an improvement in the method of manufacturing tiles, and relates more particularly to the method of manufacturing thin enameled tiles in the wet process, whereby a thin tile may be successfully manufactured which will be perfectly straight when completed.

In the accompanying drawings, Figure 1 represents a face view of a brick-blank from which a bull-nose return-tile is formed. Fig. 2 is an end view of the same. Fig. 3 is a top plan View. Fig. 4 is a top plan view of the blank after the tile portion has been partially severed from the refuse portion of the blank. Fig. 5 is a section taken in the plane of the line 5 5 of Fig. 4:. Fig. 6 is a section taken in the plane of the line 6 6 of Fig. 4. Fig. 7 is a top plan view of the refuse portion of the brick-blank after it has been severed from the tile. Fig. 8 is a top plan view of the tile. Fig. 9 is a View in isometric perspective of the tile. Fig. 10 is a view in isometric. perspective of a full return-tile without the bullnose. Fig. 11 is a View in edge elevation of a brick-blank from which a straight enameled tile is formed. Fig. 12 is an end view of the same. Fig. 13 is a top plan view. Fig. let is a top plan View of the blank after the tile portion has been partially severed from the refuse portion of the blank. Fig. 15 is a transverse section taken in the plane of the line 15 15 of Fig. 14. Fig. 16 is a top plan View of the refuse portion of the'blank after it has been severed from the tile. Fig. 17 is a top plan view of the straight tile, and Fig. 18 is an isometric perspective View of the same.

In manufacturing thin tiles in the wet process there has been great difficultyin keeping the tiles straight and avoiding warping the same while being burned in the kiln. To obltile which is held perfectly straight while being burned, the refuse portion being very readily removed from the tile after it has been completed, which refuse portion may be again utilized in the man ufact ure of the brickblank, and because of its having once been burned it serves to lessen the shrinkage of the new blanks thus formed from the material.

We will proceed to describe our improved method of making tiles.

A blank is formed of the full size ofa brick by the wet process commonly used. While the brick-blank is in its wet state, the portion of the same which is to form the tile is nearly severed therefrom. When it is' intended to manufacture a straight tile, the tile portion a of the blank A is nearly severed from the refuse portion or, by forming in the opposite faces of the blank two deep inwardly-extended kerfs a a extending the entire length of the blank and leaving a long narrow web of solid material connecting the refuse portion with the tile portion. When a return-tile is to be formed, the kerfs a a extend from one end of the blank to a point a short distance from the other end of the blank between the tile portion a and the refuse portion ct of the blank A, where they meet a kerf a which completely severs the return portion a of the tile from the refuse portion a of the blank. These kerfs may be formed in any desired manner and at the required distances from the faces of the tiles. The faces of the tile portion of the brick may be treated to an enamel coating either before or after the kerfs are formed, as may be found convenient. The blank is then completely dried and burned in a kiln in the usual manner. Because of the connection between the refuse portion and the. tile portion the tile portion is prevented from warping. Af-

ter the brick-blank has been completely dried and burned the refuse portion a may be readily broken away from the tile portion a.

This process enables us to form a full return-tile, which has hitherto been impossible in a thin tile. This process also enables us to save a large amount of material in each tile, serving the double purpose of enabling us to construct a very thin facing-wall and also saving the cost of the additional material which it has heretofore been necessary to utilize in the drying process.

What we claim is 1. The method of manufacturing returntiles consisting in forming a brick-blank, then nearly severing the tile portion in one direction and Wholly severing it in the opposite direction from the refuse portion of the blank, while in its wet state, then drying and burning the blank and finally separating the tile from the refuse portion of the blank, substantially as set forth.

2. The method of manufacturinga thin enameled tile consisting in forming a brickblank, nearly severing the tile portion from the refuse portion of the blank by forming deep kerfs in its opposite faces While in its wet state, drying and burning the blank,

coating the face of the tile portion of the blank With an enamel intermediate the formation of the blank and the drying and burn- ,ing of the same and finally separating the tile portion from the refuse portion of the blank, substantially as set forth.

In testimony that we claim the foregoing as ourinvention we have signed our names, in presence of two Witnesses, this 21st day of September, 1900.
