Year: 1871

page_text: LETTERS PATENT to Edward Thomas Hughes, of the Firm of Hughes
and Son, Patent Agents, 123, Chancery Lane, London, for the
Invention of "AN IMPROVED PROCESS FOR PRINTING ON ENAMELLED OR
VITREOUS SURFACES."-A communication from abroad by Samuel
James Hoggson, of New Haven, County of New Haven, State of
PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition, on
the 21st November 1871.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent
Agents, 123, Chancery Lane, London, do hereby declare the nature of
the said Invention for "AN IMPROVED PROCESS FOR PRINTING ON ENAMELLED
OR VITREOUS SURFACES," a communication to me from abroad by Samuel
James Hoggson, of New Haven, County of New Haven, State of
Connecticut, United States of America, to be as follows:-
This Invention relates to an improved process for ornamenting, letter-
ing, or figuring enamelled or vitreous surfaces, such as china, porcelain,

page_text: glass, or similar materials.
This has heretofore been done on enamelled
articles previous to enamelling, the enamel covering the figures made
upon the unglazed surface.
The object of this Invention is to improve the process by producing
the required figures or ornamentation in a simpler and more perfect t
manner, and it consists in printing directly upon an enamelled or
vitreous surface with elastic or flexible type, employing as a printing
material an enamel, and after so printing to fuse the enamel of the
printed figures by means of heat in an oven or otherwise.
I take the article to be ornamented, its surface having been previously 1
finished, and having prepared an enamel of the required color, I coat an
elastic or other suitable type with this enamel, then press the type upon
the surface where the figure is to be set, removing the type the enamel
is left on the surface, and is then submitted to the heat to fuse the
enamel of the figure; the work is now complete, and is much more 1
perfect than the ordinary handwork on the unglazed surface, as the best
press work is better than hand printing.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent
Office on the 21st May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents, 123,
Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 1
Letters Patent, bearing date the Twenty-first day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Thomas Hughes, Her special
licence that I, the said Edward Thomas Hughes, my executors, adminis- 3
trators, and assigns, or such others as I, the said Edward Thomas
Hughes, my executors, administrators, and assigns, should at any time

page_text: agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED PROCESS FOR PRINTING ON ENAMELLED OR VITREOUS SURFACES,"
a communication to me from abroad by Samuel James Hoggson, of
New Haven, County of New Haven, State of Connecticut, United
States of America, upon the condition (amongst others) that I, the
said Edward Thomas Hughes, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters

page_text: perfect than the ordinary hand work on the unglazed surface, as the best
press work is better than hand printing.
The same process of printing may be applied to a glass surface.
Having now described my said Invention, and the manner in which
the same is to be performed, I wish it to be known that I claim the
herein described process for printing on enamelled or vitreous surfaces,
consisting in the employment of a fusible enamel applied by a type or
similar device to give the requisite impression.
In witness whereof, I, the said Edward Thomas Hughes, have here-
unto set my hand and seal, this Twenty-first day of May One 1
thousand eight hundred and seventy-two.
