JOHN Gr. LOV, OF CHELSEA, MASSACHUSETTS.
IMPROVEMENT lIN THE NlA-NUFACTURE OF DECORATIVE TILES.
Specification forming part of Letters Patent No. 212,47, dated February 18,1879 application iiled January 24, 1879.
To all whom it may concern:
Be it known that I, JOHN G. Low, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented an Improvement in the Manufacture of Decorative Tiles,
of which the following is a specification:
Decorative tiles may be classified, according to their decorations, into four general sorts: First, those made with liat surfaces, and either of a natural or artificial monochrome without designs, called self-colored tiles,77 or ornamented with surface-enamel, or painting in outline, monochrome, or polychrome; second, those made with liat surfaces, inlaid in chromatic `patterns to a slight depth, otherwise known as encaustic tiles, third, those made with designs in relief; fourth, those made with irregular, incised, indented, or depressed designs, having texture in the depressions. Either of the last two sorts may be painted in monochrome or polychrome, and either of the four sorts may be glazed either with a colorless glaze or with a colored glaze, or may be enameled.
The distinction now insisted upon is the condition of the exposed surface, whether plane or irregular, either by relief or intaglio ornamentation.
The first part of my improvements relates to means of decorating the surface by intaglio and relief ornamentation.
The second part of my improvements relates to means of providing the backs of tiles with dovetailed or cramping grooves or holding places for attachment.
State of the Art- Prior to 1840 all tiles, so far as known, were made from wet clay, beat up in molds, at first in plaster molds, and later in brass molds. In that year the Prosser patent was taken in England, June 17, for compressing buttons from clay-dust, and was subsequently applied to the manufact-ure of tiles by the Mintons, Maw, and others. By this process flat tile were produced by compression in molds from dry clay-dust; and either by arabesque designs on the face of the plunger or platen, usually the plunger, of the mold, or by engraving-tools, an indention was produced, into which slip 7 was introduced,
Another and later method of using dustclay. is known as the Boulton and Worthing- 'ton process, and used by Malkin 85 Co. It consists in the use of metallic boxes, fitted with plungers and fashioned like the arabesques or other patterns, to be used as ornaments, in which the design-clay dusts are compressed within a frame, which frame is afterward, the boxes and plungers being first removed, filled with clay-dust of the ground color, which is compressed within the frame and around the pattern made as stated, and the whole then fired, but up to the present time, so far as I am informed, no relief-tiles or intaglio tiles having texture in the depressions have been made in whole or in part by compression out of clay-dust, and certainly no tiles having undercut7 designs have been made in any part out of compressed clay-dust.
My present invent-ion, so far as it relates to surfacing tile, consists in the production and preparation of the molds for embossing or indenting tile made of clay-dust, to the preservation and use of such molds, to the formation of undercut gures by the aid of such molds, and to the making of compact homogeneous clay-dust tiles, having surfaces ornayproducing a flat thin plastic plate of about the thickness of a tile; or I take a quantity of clay-dust and similarly compress it, and saturate said dust with paraffne. The upwardlypresenting surface of this plate is then plentifully sprinkled with pulverized plumbago, which is compressed into the surface of the plate.
The compressed plate may now be engraved with any desired pattern, and, care being taken to cover with blacklead powder, brushed on which, on firing, formed the chromatic pattern with naphtha, or any other solvent of parafne as avehicle, or dusted onto a slightly-warmed inlaid on the at surface.
surface, or stippled on with a stippling-brush, the parts denuded by engraving can be used as an electrotype-mold to make a reverse, and the electrotype used as a matrix to make an obverse. These electrotypes, well backed, as when used for printing, and set in steel. or oth er strong boxes to prevent crush of the backing, will serve as dies for making the intaglios and reliefs for stamping tile in dry clay-dust.
.In case high reliefs are desired, the paraffine (or, better, the clay and parafne) plate may be carved as desired, carefully avoiding undercutting, and then covered with its plumbago surface, by the naphtha process or stipplin g, and electrotyped and used as the die.
Vhen high reliefs, which it is desirable to undercut, are to be made, the mold is made so that the compressed clay will draw, and, the main part of the design being thus formed, the modeller carves the undercutting byhand, the clay being sufficiently tenacious when compressed to allow this, and the iinished tile, partly hand-made and partly machine-made, is then fired.
For obtaining textures, low reliefs, or intaglios of natural objects, and the like, I may, if I desire, usethe paraffine plate made, as Ihave described above, with plumbago surface, for
electrotyping; but, instead of engraving it, I
form an impression in its blaclcleatled surface by the objects I wish to represent, in the manner hereinafter described for unleaded parafine or clay-dust. I prefer, however, as it gives me great variety in design with slight expense, to adopt the following manipulation: Having formed the compressed plate, as already described, I raise in the tile-frame of the tile-machine the lower platen till the upper surface of the compressed plate is conveniently near the top of the frame, and compose upon the surface, by laying thereon bits of woven stuff, lace, pieces of embossed paper, leather or other fabric, leaves, grasses,owers, or other objects having suitable textures and outlines, such a design as I think will be attractive. I then lower the platen to place, and bring down the plunger with strong' compression upon the objects. By this means they are indented in outline and texture in the plastic or clay-dust surface, even overlays being represented with an accuracy absolutely true to nature, and always in intaglio.
As already said, this intaglio may be used as a mold for electrotypes, when properly made, by use of pulverized plumbago as a surfacing agent; but I usually take this matrix so made and place over it a diaphragm of thin tough materiala rubber iilm will serve, and many other materials but the best and cheapest I have yet found is the thin Japanese paper, of uniform texture and great toughness, such as appears in the Japanese handkerchiefs` and napkins, so called. This diaphragm must exactly cover the surface of the intaglio. Upon it is next laid the dust of surface and bodyclay of the tile to be embossed, which is subjected to compression in the ordinary way, and
thereupon, on raising the plunger and platen, the intaglio and relief may be separated, the diaphragm peeled by aid of a sharp tool `to start it from the die, usually the relief, vto which it generally, if not always, adheres, and the intaglio will usually, with proper care in handling, b'e found perfectly uninj ured during several hundred impressions.
When the surface is of one clay and the body of another, each clay is to be separately compressed, unless sgmzito effects are desired, in which case the surface-layer must be carefully applied, so as to not cover the pattern desired to be of the color of the body-clay.
The sharpness and definition of texture of reliefs made from dust-clay intaglios are very remarkable, an d tile compressed from dust from its homogeneous quality is much less likely to warp or shrink unevenly in ring than any other, particularly if packed in a less fusibleV powder, like quartz grains or ganister in firing, as is not unusual with terra-cotta relief-work. By these means I obtain what has long been a desideratum in relief tile-work-a compact homogeneous embossed tile of uniform quality and slight shrinkage-more surely than has ever been done before. f
It may often be desirable to obtain .in tile both the relief and intaglio of the impression in the clay-dust. In this case the relief can be used upon the platen in the same way as the intaglio. Two of these tile, an intaglio and a relief', may be placed face to face in the seggar for firing, and usually will separate on removal; but I prefer to insure this by leaving the paper diaphragm between them.
In case the design is to be reproduced smaller, the shrunk ired tile may be blackleaded and electrotyped. f
Of course these tile may have their intaglios l filled with, or their reliefs covered with, kiln colors, slip, or enamel, either while simply vclay or after firing, in any way and at any l. time proper in tile-making for such application 5 but this is no part of my invention.
No good method of fixing wall-tiles has yet been contrived, except those used by the ancients of Hanging or beveling the edges backward and forward on alternate sides or in al ternating section on the same side, or in constructing them with holes partly parallel 'to their surfaces for cramps or wires extending into the plastic cement, all of which are costly, and none of which are adapted for compressed clay-dust work.-
Lately on occasions, in wet-clay work, undercut cramp-grooves have been made by hand; but these are costly and inapplicable to dustwork.
I employ the following means for forming dovetailed grooves on the backs of tile:' I cut one or more pieces of wood of dovetailed cross-section to such length as may be desirable, usually long enough to extend clear vacross one way, and lay them on the platen of the tile-machine, narrow side down, and fill in the clay-dust upon them, or I place them on top of the lled-in dust narrow side up, according as the face of the tile is to beup or down. In compression the narrow face of the wood will be level withthe back of the tile, and the clay-dust will mold round it. In firing these formers will burn out, leaving their grooves, and this, if the wood be soft, light, and dry, without much, if any, chance of injury to the tile.
Many things may be used as substitutes for parattines, such as waxes, and compounds of waxes, resins, gums, &c. 5 but I have not considered it requisite to enumerate them, as they would clearly be equivalents if their qualities of toughness, exibility, and plasticity resembled those of parafne.
The dust used should be fine enough to pass a one-hundred-mesh sieve at largest.
I claim as my inventionl. The carved paraffme matrix surfaced with plumb-ago, as an electrotype-mold for tile-dies.
2. 'The paraflne matrix formed by compression, coated with plumbago, as described, and carrying incised or indented patterns, as an electrotype-mold for tile-dies.
