page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIP
BROOKES, of Shelton, in the Potteries, Staffordshire, Engraver, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-first day of June, One thousand eight
hundred and twenty-five, in the sixth year of His reign, did, for Himself,
His heirs and successors, give and grant unto me, the said Philip Brookes,
His especial licence, that I, the said Philip Brookes, my exors, admors, and
assigns, or such others as I, the said Philip Brookes, my exors, admors, and
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT IN THE PREPA-
RATION OF A CERTAIN COMPOSITION, AND THE APPLICATION THEREOP TO THE
MAKING OP DIES, MOULDS, OR MATRIXES, SMOOTH SURFACES, AND VARIOUS
OTHER USEFUL ARTICLES;" in which said Letters Patent is contained a pro-
viso obliging.me, the said Philip Brookes, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my
said Invention, and in what manner the same is to be performed, and to cause
the same to be inrolled in His Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Philip Brookes, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are parti-
cularly described and ascertained in the following description thereof (that is
to say):-
In the first place, I declare that my said improvement applies to the manu-
facturing and preparing of dies, moulds, matrixes, or stamps of a certain
combination of siliceous, argillaceous, calcareous, vitrescent, and barytic
earths, or other natural earthy compounds, as granite, felspar, clays, marls,
flint, cank stone, or any other material used by potters, which dies, moulds,
matrixes, or stamps, as aforesaid, undergo a certain degree of vitrification by
heat, then to be used and applied for the purpose of embossing, by stamping or
otherwise, representations or resemblances of figures, vases, buildings, ruins,
and all other fancy and ornamental subjects, articles, matters, or things, in
paper, leather, horn, Bristol board, mill board, bone, tortoiseshell, ivory,
imitation pearl, papier mache, composition, cement, or paste.
In the second place, for manufacturing and preparing a certain combination
of siliceous, argillaceous, calcareous, vitrescent, and barytic earths, or other
natural earthy compounds, as granite, felspar, clays, marls, flint, cank stone, or
any other material used by potters, into tabular plates with smooth surfaces
resembling tiles or slates, by means of mechanical pressure between metallic
blocks, which artificial slates or tiles are to undergo a certain degree of vitrifi-
cation by heat, and to be used and applied for the purpose of drawing, writing,
printing, and painting upon with blacklead, chalk, crayons, water colours, oil
colours, or any other material used by painters; also for manufacturing and
preparing, by means of mechanical pressure between metallic blocks and by
the subsequent application of heat, slates or tiles with smooth surfaces,
vitreous or absorbent, with enamelled surfaces of the above-mentioned materials
used by potters for the purpose of enamel painting, guilding, &c.; also for
manufacturing and preparing of the last-mentioned materials by means of
mechanical pressure between metallic blocks, and by the subsequent application
of heat, smooth surfaces to be used and applied either with or without a
coating of glaze for chimney pieces and all architectural purposes for which
they are adapted.
In witness whereof, I, the said Philip Brookes, have hereunto set my
hand and seal, this Thirteenth day of December, in the year of our
Lord One thousand eight hundred and twenty-five.
PHILIP (LS.) BROOKES.
