Year: 1866

page_text: LETTERS PATENT to Samuel Parry, of 10, Thackeray Street, Liverpool,
in the County of Lancaster, Master Mariner, for the Invention of "AN.
IMPROVED COMPOSITION FOR THE COATING OF THE BOTTOMS OF SHIPS AND OTHER
VESSELS."
Sealed the 11th June 1867, and dated the 20th December 1866.
PROVISIONAL SPECIFICATION left by the said Samuel Parry at the Office
of the Commissioners of, Patents, with his Petition, on the 20th December
1866.
I, SAMUEL PARRY, of 10, Thackeray Street, Liverpool, in the County of
Lancaster, Master Mariner, do hereby declare the nature of the said Invention
for "AN IMPROVED COMPOSITION FOR THE COATING OF THE BOTTOMS OF SHIPS AND
OTHER VESSELS," to be as follows:―
The improved composition is applicable to ships or other vessels constructed
of either wood or iron for the protection of them from the formation of
barnacles and from other accumulations.
The ingredients and proportions of them which I prefer are as follows:-
20 gallons of palm oil; 2 gallons of boiled linseed oil; 14 lbs. of arsenic ;
6 lbs. of red lead; 6 lbs. of dryers, preferring that description of dryers com-
monly called "patent dryers;" 4 lbs. of oxide of iron. Of these the boiled
linseed oil, arsenic, red lead, dryers, and oxide of iron are first mixed, and
then with the palm oil when that oil is in a boiling state, and the whole is
then well mixed together.

page_text: The application to the ships' or vessels' bottoms should be when the com-
position is in a boiling state; brushes are useful in applying the composition,
and it may be kept boiling in small pots kept over fires arranged along the
ships' or vessels' bottoms. Before applying the composition I prefer to give
the bottom of the ship or vessel-two-coats of zinc white with which has been
mixed a small quantity of oxide of iron; I then generally apply two coats of
the composition. The proportions of the ingredients may be varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Parry in the Great Seal Patent Office on the
15th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
PARRY, of 10, Thackeray Street, Liverpool, in the County of Lancaster,
Master Mariner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Iler reign,
lid, for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Parry, Her special licence that I, the said Samuel Parry, my executors,
administrators, and assigns, or such others as I, the said Samuel Parry, 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 THE COATING OF
THE BOTTOMS OF SHIPS AND OTHER VESSELS," upon the condition (amongst others)
that I, the said Samuel Parry, my executors or administrators, by an instru-.
ment 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 Samuel Parry, do hereby declare the
nature of the spid Invention, and in, what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof; that is to say:-
The improved composition is applicable to ships or other vessels constructed

page_text: of either wood or iron for the protection of them from the formation of
barnacles and from other accumulations.
The ingredients and proportions of them which I prefer are as follows:-
20 gallons of palm oil; 2 gallons of boiled linseed oil; 14 lbs. of arsenic;
6 lbs. of red lead; 6 lbs. of dryers, preferring that description of dryers com-
monly called patent dryers; 4 lbs. of oxide of iron. Of these the boiled
linseed oil, arsenic, red lead, dryers, and oxide of iron are first mixed together,
and then with the palm oil when that oil is in a boiling state, and the whole
is then well mixed together.
The application to the ships' or vessels' bottoms should be when the com-
position is in a boiling state; brushes are useful in applying the composition,
and it may be kept boiling in small pots kept over fires arranged along the
ships' or vessels' bottoms. Before applying the composition I prefer to give
the bottom of the ship or vessel two coats of zinc white with which has been
mixed a small quantity of oxide of iron; I then generally apply two coats of
the composition.
Having thus described my Invention, and the means which I adopt in the
use of the same, I would have it understood that although I have given the
proportions of the various ingredients which I have found to answer well, I do
not confine myself to these proportions, as the same may be varied without
departing from the peculiar character of the Invention.
In witness whereof, I, the said Samuel Parry, have hereunto set any hand
and seal, this 28th day of December, in the year of our Lord One
thousand eight hundred and sixty-six.
SAMUEL PARRY. (L.S.)
