Year: 1856

page_text: LETTERS PATENT to John Gedge, of No. 4, Wellington Street South,
Strand, in the County of Middlesex, Patent Agent, for the Invention of
"IMPROVEMENTS IN PAINT OR COLORING MATTER, APPLICABLE TO COATING
METALS AND OTHER SUBSTANCES, WHEREBY THE OXIDATION OF METAL IS
PREVENTED, AND RESISTANCE TO THE ACTION OF THE ATMOSPHERE, RAYS OF
HEAT, OR ACIDS IS SECURED."-A communication from Allan Macpherson,
of Brussels, in the Kingdom of Belgium.
Sealed the 3rd March 1857, and dated the 11th September 1856.
PROVISIONAL SPECIFICATION left by the said John Gedge at the Office
of the Commissioners of Patents, with his Petition, on the 11th September
1856.
I, JOHN GEDGE, of No. 4, Wellington Street South, Strand, in the County
of Middlesex, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PAINT OR COLORING MATTER, APPLICABLE TO COATING
METALS AND OTHER SUBSTANCES, WHEREBY THE OXIDATION OF METAL IS PREVENTED,
AND RESISTANCE TO THE ACTION OF THE ATMOSPHERE, RAYS OF HEAT, OR ACIDS IS
SECURED," communicated to me by Allan Macpherson, of Brussels, in the
Kingdom of Belgium, to be as follows:-
I propose obtaining a varnish, paint, or coloring matter which when applied
to metals or other substances will adhere perfectly thereto, be impervious to
the several actions of humidity, atmospheric heat, and acids, prevent the
oxidation of any metal that may be coated with it, and in fact enable the

page_text: article so coated to resist exterior destructive action. To effect this, I take
a metal pot or vase in which I mix Jews' pitch with an essence known as
Bayonne essence," in the proportion of one-fourth Jews' pitch to three-
fourths essence, or thereabouts; I then submit the preparation to a moderate
heat, taking care to stir it during the operation. It may be applied by
immersion of the metal therein, or in the usual manner of painting by a
brush.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Gedge in the Great Seal Patent Office on the
10th March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GEDGE, of No. 4, Wellington Street South, Strand, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of September, in the year of our Lord
One thousand eight hundred and fifty-six, and in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Gedge, Her especial license that I, the said John Gedge, my
executors, administrators, and assigns, or such others as I, the said John
Gedge, 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 "IMPROVELIENTS IN PAINT OR
COLORING MATTER, APPLICABLE TO COATING METALS AND OTHER SUBSTANCES, WHEREBY
THE OXIDATION OF METAL IS PREVENTED, AND RESISTANCE TO THE ACTION OF THE
ATMOSPHERE, RAYS OF HEAT, OR ACIDS IS SECURED," the said Invention having
been communicated to me by Allan Macpherson, of Brussels, in the Kingdom
of Belgium, upon the condition (amongst others) that I, the said John
Gedge, 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 Patent.
NOW KNOW YE, that I, the said John Gedge, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement:-
The object of this Invention is to obtain a varnish, paint, or coloring
matter which when applied to metals or other substances will adhere firmly
thereto, be impervious to the several actions of humidity, atmospheric heat,
or acids. By admixture of the substances, herein-after named, I have succeeded
in obtaining a varnish, paint, or coloring matter possessing these properties,
the use of which prevents oxidation of any metal which may be coated with
it, and otherwise renders articles so coated or painted capable of resisting
exterior destructive action. To obtain this paint, varnish, or coloring matter
I mix in a metal pot or other appropriate vessel "Jews' pitch" with an essence
known in commerce as "Bayonne essence," in the following proportions, say,
to one quarter of a hundredweight of Jews' pitch I add three quarters of a
hundredweight of essence of Bayonne; I then apply moderate heat, taking
care to stir or mix up the composition till the two substances are completely
incorporated. The article to be coated with this composition may either be
immersed in the fluid mixture, or the paint may be applied by brush, in the
usual manner of coating substances with paint.
Having now described the nature of the Invention, communicated to me,
I would here remark, that while I have given the component parts of the
mixture as it is usually used, yet I do not confine myself to the exact pro-
portions of pitch and essence herein given, as some variation may be required,
from the better or inferior nature of the articles mentioned, as the component
parts of the said varnish, paint, or coloring matter.
In witness whereof, I the said John Gedge, have hereunto affixed my
hand and seal, this Tenth day of March, in the year of our Lord One
thousand eight hundred and fifty-seven.
Witness,
W. E. GEDGE,
Danes Inn, Strand, London.
JOHN GEDGE. (L.S.)
