HANGINGS AND ALL SORTS OF PAPERS MADE WATERPROOP BY A NEW PROCESS
Year: 1858

page_text: LETTERS PATENT to Jacques Grassay, residing at Ivry, Rue du Chevaleret,
7, Paris (Seine), in the Empire of France, for the Invention of "HANGINGS
AND ALL SORTS OF PAPERS MADE WATERPROOP BY A NEW PROCESS."
Sealed the 12th October 1858, and dated the 17th April 1858.
PROVISIONAL SPECIFICATION left by the said Jacques Grassay at the
Office of the Commissioners of Patents, with his Petition, on the
17th April 1858.
I, JACQUES GRASSAY, residing at Ivry, Rue du Chevaleret, 7, Paris, (Seine,)
in the Empire of France, do hereby declare the nature of the said Invention
for "HANGINGS AND ALL SORTS OF PAPERS MADE WATERPROOF BY A NEW PROCESS,"
to be as follows:-
The present Invention has for object the composition of a waterproof
coating, which can be used for all kinds of decorative & other papers
without spoiling or changing their appearance. The advantages resulting
from this Invention are too evident to need enumeration; we will only say,
that for preserving decorations and paper for the walls of rooms our system
surpasses all others hitherto used, as the papers spread with this coating not
only retain all the brightness of their colors, but remain perfectly unaffected
by the dampness of the walls.
The coating spread in a layer on both sides of the paper permits of its
being rolled and carried in the ordinary way; it remains perfectly smooth and
dry, and can be cut into festoons, borders, and in fact used in the same manner
as unprepared paper.

Hydraulic or common lime
-
3 oz.
All these ingredients are well mixed together and reduced to a liquid state,
then spread quite warm on the paper, which dries almost immediately, when
it can be rolled up or used as the case may require.
All painted or gilt papers, of whatever color or nature, may be spread over
with this coating, without its producing the slightest alteration in color or
ornamental design.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jacques Grassay in the Great Seal Patent Office on the
15th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACQUES
GRASSAY, residing at Ivry, Rue du Chevaleret, 7, Paris (Seine), in the Empire
of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jacques Grassay, Her special licence that I, the said Jacques Grassay;
my executors, administrators, and assigns, or such others as I, the said
Jacques Grassay, 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 "HANGINGS AND ALL
SORTS OF PAPERS MADE WATERPROOF BY A NEW PROCESS," upon the condition
(amongst others) that I, the said Jacques Grassay, my executors or adminis
trators, 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 Jacques Grassay, do hereby declare the

page_text: nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
The present Invention has for object the composition of a waterproof
5 coating, which can be used for all kinds of decorative & other papers
without spoiling or changing their appearance. The advantages resulting from
this Invention are too evident to need enumeration; we will only say that,
for preserving decorations and paper for the walls of rooms, our system
surpasses all others hitherto used, as the papers spread with this coating not
only retain all the brightness of their colors, but remain perfectly unaffected
by the dampness of the walls.
This coating, spread in a thin layer on both sides of the paper, permits of
its being rolled and carried in the ordinary way; it remains perfectly smooth
and dry, and can be cut into festoons, borders, in fact, used in the same
manner as unprepared paper.
Composition for the coating:-
Mineral tar-
Resin
-
Litharge
Hydraulic or common lime

this coating, without its producing the slightest alteration in color or in
ornamental design.

hand and seal, this 15th day of October, in the year of our Lord
One thousand eight hundred and fifty-eight.
