Year: 1874

page_text: LETTERS PATENT to Thomas Skinner, of Sheffield, in the County of
•
York, Etcher, for the Invention of "IMPROVEMENTS IN THE MODE OR
PROCESS OF ETCHING ON STEEL OR IRON OR OTHER METAL OR SUBSTANCE."
Sealed the 3rd November 1874, and dated the 4th May 1874.
PROVISIONAL SPECIFICATION left by the said Thomas Skinner at the
Office of the Commissioners of Patents, with his Petition, on the
4th May 1874.
I, THOMAS SKINNER, of Sheffield, in the County of York, Etcher, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MODE OR PROCESS OF ETCHING ON STEEL OR IRON OR OTHER METAL OR
SUBSTANCE," to be as follows:-
It has long been known that a process of etching can be performed
by the transferring certain letters, marks, drawings, and various designs,
first made on plates of iron, steel, copper, and other substances,
from which prints or transfers are taken on paper and other surfaces;
these are then laid on the articles to be etched and the impression
transferred thereto in the ordinary way, as well known,

page_text: My Invention has for its object the dispensing with the circuitous
mode above described, and it consists in the preparation of a composition
formed of materials to resist acids and convey or make deposits of this
substance upon or to flexible type and other moulds, models, or
designs.
And the Invention further consists in the application and use of the
above composition or substance, by and with flexible type and other
moulds, models, or designs, and for the transferring of the letters or im-
pressions direct from these agents to the articles to be etched on steel,
iron, metals, and other substances.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Thomas Skinner in the Great Seal Patent Office
on the 3rd November 1874.
-
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,-THOMAS
SKINNER, of Sheffield, in the County of York, Etcher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Skinner, Her special licence
that I, the said Thomas Skinner, my executors, administrators, and
assigns, or such others as I, the said Thomas Skinner, my executors,
administrators, and assigns, should at any time 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 "IMPROVEMENTS IN
THE MODE OR PROCESS OF ETCHING ON STEEL OR IRON OR OTHER METAL OR
SUBSTANCE," upon the condition (amongst others) that I, the said Thomas
Skinner, 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

page_text: in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Skinner, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement in writing, that is to say:
manner
This Invention relates to improvements in the mode or process of
etching on steel or iron, or other metal or substance, and the manı
in which the same is to be performed or carried into practical effect, is
particularly described and ascertained in and by the following statement
thereof, that is to say:
It has long been known that a process of etching can be performed
by the transferring certain letters, marks, Drawings, and various designs,
first made on plates of iron, steel, copper, and other substances, from
which prints or transfers are taken on paper or other surfaces, these are
then laid on the articles to be etched, and the impression is transferred
thereto in the ordinary way, as is well known.
My Invention has for its objoct the dispensing with the circuitous
mode above described, and it consists, firstly, in the preparation of a
composition formed or made of the following materials, and in the pro-
portions as follows or thereabouts, namely, I dissolve or melt two parts
of beeswax and one part of resin, two parts of beeswax and one part of
asphaltum, two parts of beeswax and one part of lampblack, two parts of
beeswax and one part of Venetian red. I use any two or more of
these or any other substances that will resist acids. This composition
thus formed is to be applied in such a manner as to convey or make
deposits of this substance upon or to flexible type or other moulds,
models, or designs of a flexible kind..
My Invention consists, secondly, in the application and use of the
above-named composition or substance by and with the flexible type and
other moulds, models, and designs that may be used for the transferring
of the letters or impressions made therewith direct from these agents
on to the articles to be etched either on steel, iron, metals, or on other
substances in place of the modes above described and hitherto adopted.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I have to state in conclusion that
