Year: 1866

page_text: LETTERS PATENT to Richard Jarraud Gay, of Badshot-Lee, Farnham, in
the County of Surrey, for the Invention of "AN IMPROVED COMPOSITION"
FOR COATING WALLS OR OTHER SURFACES SO AS TO RENDER THEN IMPERVIOUS
TO THE ACTION OF WATER OR MOISTURE."
PROVISIONAL SPECIFICATION left by the said Richard Jarraud Gay
at the Office of the Commissioners of Patents, with his Petition, on the
3rd November 1866.
I, RICHARD JARRAUD GAY, of Badshot-Lee, Farnham, in the County of
Surrey, do hereby declare the nature of the said Invention for "AN IMPROVED
COMPOSITION FOR COATING WALLS OR OTHER SURFACES SO AS TO RENDER THEM
IMPERVIOUS TO THE ACTION OF WATER OR MOISTURE," to be as follows:-
This Invention consists in combining together the following ingredients,
matters, or substances:-I take from 140 to 150 parts of mythilated finish,
50 to 60 parts of shell-lac, 50 to 60 parts of any resinous matter, 1 to 3 parts
of litharge, and 9 to 12 parts of any boiled vegetable oil. I proceed as
follows:-I first mix the mythilated finish with the shell-lac and resinous.
matters, and subject them to heat sufficient to dissolve the shell-lac and
resinous matters, by preference I use a boiler or vessel surrounded by a jacket,
into which steam or water is admitted; I then mix the litharge with the boiled
oil in a separate vessel, and submit them to the action of heat sufficient to

page_text: expel or evaporate all the water contained in the oil; I then mix the oil and
litharge thoroughly together, and place them in the boiler containing the
dissolved shell-lac and resin, and mix the whole thoroughly together whilst
they are under the action of heat. I propose, if desirable, to color the above
composition with any coloring matter capable of amalgamating therewith.
The above composition when cool I strain and. place in air-tight vessels ready
for use.
The composition may be applied. to the surface of walls by any
ordinary brush such, as is used by painters.,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Jarraud Gay in the Great Seal Patent Office on the
3rd May 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
JARRAUD GAY, of Badshot-Lee, Farnham, in the County of, Surrey,' send

said Richard Jarraud Gay, Her special licence that I, the said Richard
Jarraud Gay, my executors, administrators, and assigns, or such others as
I, the said Richard Jarraud Gay, 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 "AN
IMPROVED COMPOSITION FOR COATING WALLS OR OTHER SURFACES SO AS TO RENDER"
THEM IMPERVIOUS TO THE ACTION OF WATER OR MOISTURE," upon the condition
(amongst others) that I, the said Richard Jarraud Gay, 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

Patent.
:
NOW KNOW YE, that I, the said Richard Jarraud Gay, do hereby
declare the nature of the said Invention, and in what manner the same is

page_text: to be performed, to be particularly described, and, ascertained in and by the
following statement, that is to say:-
This Invention consists in combining together the following ingredients,
matters, or substances:-I take from 140 to 150 parts of mythilated finish,
50 to 60 parts of shell-lac, 50 to 60 parts of any resinous matters, 1 to 3 parts
of litharge, and 9 to 12 parts of any boiled vegetable oil. I proceed to mix
these ingredients, matters, or substances together as follows:-I first mix the
mythilated finish with the shell-lac and resinous matters, and subject them to
a degree of heat sufficient to dissolve the shell-lac and resinous matters, by
preference I use a boiler or vessel surrounded by a jacket, into which steam
or hot water is admitted; I then mix the litharge with the boiled oil in a
separate vessel of any convenient size and form, and submit them to the
action of heat sufficient to expel or evaporate all the water contained in the
oil; I then mix the oil and litharge thoroughly together by any suitable means,
and place them in the boiler containing the dissolved shell-lac and resin, and
mix the whole thoroughly together by any suitable means whilst they are under
the action of heat. I propose, if desirable, to color the above composition
with any coloring matter capable of amalgamating therewith, the above com-
position when cool I strain and place in air-tight vessels ready for use. TLe
composition may be applied to the surface of walls or other surfaces by any
ordinary brush, such as is used by painters.
Having now described and set forth the nature and object of my said
Invention for "An Improved Composition for Coating Walls or other Surfaces
so as to render them Impervious to the Action of Water or Moisture," together
with the best means I am acquainted with for carrying the same into practical
effect, I would remark in conclusion that I hereby declare my Invention
to consist in and I claim combining the ingredients, matters, or substances
above mentioned into a composition suitable for coating walls or other surfaces
as above stated. .
.
In witness whereof, I, the said Richard Jarraud Gay, have hereunto set
my
hand and seal, this Third day of May, in the year of our Lord
One thousand eight hundred and sixty-seven.
