and the like upon Glass and other Surfaces
We, CHARLES FRANCIS BULLARD BIRCHALL and ALEXANDER WOOD both of No 5
Mark Lane in the City of London, Gentlemen, and JAMES BUDD of No 33 Peckham
Grove, Camberwell in the County of Surrey, Manufacturer do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
-
Our invention relates to an improved method or process of reproducing fic-similes,
portraits, designs, or the like, on smooth, rough, flat, convex, concave, or other surfaces
The main object of our invention is to provide for staining, coloring, embossing,
and decorating glass (whether transparent or opaque) porcelain, china, earthenware,
wood, marble, stone, plaster, papiermiche or other materials for windows, lights,
panels, tiles, advertising signs, tablets, or notifications, or for ornamentation or for
other purposes for which such colored, embossed, and decorated glass or other materials
are applicable
In practicing our invention we employ, in addition to the surface or surfaces upon
which the designs or the like are to be reproduced, lithographic stones, engraved
plates of copper, zinc, or other metal, wood-blocks, or the compressed plates in
common use in the lithographic printing trade
If we employ a lithographic stone, we draw thereon with a pen or brush, and with
lithographic-ink, lithographic chalk, or other suitable material, the facsimile design, or
the like to be reproduced If we use an engraved wood-block or plate, we roll on or
rub into the engraved parts thereof, lithographic-ink, dye, common paint or other
coloring matter We then, by the ud of rocher or roller, covered with the roller
composition usually employed by printers or with other suitable composition, convey
or transfer the facsimile, design or the like from the lithographic stone, wood block,
or plate, to the glass or other surface
It desirable, the facsimile, design, portrait, or subject is fixed by means of fluoric
acid, the glass or other material either being immersed bodily in the said cid or
being subjected to its influence in any other convenient manner, for a period of about
twenty minutes. When fixing is resorted to we find it desirable to mix with the inks,

page_text: dyes, or other paints or colors used, a small quantity of palm oil, which renders the
design less liable to be affected by the acid in the process of fixing
We may color the sud facsimile design or subject by land (drawing or painting
in the ordinary minner) or by machinery or otherwise, and we complete the same if
required by conting it all over with transparent or glassy coiting applied by
means of sprayer, splisher or the like The solution used for this conting is obtained
by mixing equal quantities of white shell c, (or gum), naptha, white varnish und
methylated spirits, (or spirits of wine) The object gained by the application of the
sud solution is, thit it holds fist the said facsimile, design, or subject, and protects
the same gunst atmospheric and other destructive influences
Our sud invention, in so fir as it applies to china, glass, earthenware, and the like,
19 substitute for the burning-in process
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
cl um 15
1st The improved method of reproducing designs, facsimiles, or the like, on gliss
and other surfices, by transferring them from a lithographic stone or a wood or
other block, and applying a protective conting to the sud suifice, substantially as
hereinbefore described
2ndly The use of a covered rocker or roller as above described for the purpose of
transferring the design from the stone or other block to the surfice upon which the
design is to be reproduced
