Year: 1864

page_text: LETTERS PATENT to Laurent Paviola, of La Ciotat, in the Empire of
France, Joiner, for the Invention of "AN IMPROVED ANTI-SALINE COATING
CHIEFLY APPLICABLE FOR PRESERVING FROM CORROSION AND INCRUSTATION THE
BOILERS AND PIPES OF MARINE STEAM ENGINES."
Sealed the 13th April 1865, and dated the 21st October 1864.
PROVISIONAL SPECIFICATION left by the said Laurent Paviola at
the Office of the Commissioners of Patents, with his Petition, on
the 21st October 1864.
I, LAURENT PAVIOLA, of La Ciotat, in the Empire of France, Joiner, do
hereby declare the nature of the said Invention for "AN IMPROVED ANTI-SALINE
COATING CHIEFLY APPLICABLE FOR PRESERVING FROM CORROSION AND INCRUSTATION
THE BOILERS AND PIPES OF MARINE STEAM ENGINES," to be as follows:-
The anti-saline coating, the subject of this Invention, is chiefly applicable
to the preservation of the boilers of steam ships. It is composed of alum
and of white powder of saponaria, mixed and dissolved in soft water, and in
equal proportions and not only has the property of preserving the metals com-
posing the body of the boiler and its apparatus from the corrosive action of the
salt, but further (and this appears to me the most important point), that of
removing without any injury to the metal the salt coatings or incrustations

page_text: which form in the interior of the pipes and of the body of the steam boiler.
This coating is applied with a brush, or in any other manner which may be
deemed suitable.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Laurent Paviola in the Great Seal Patent Office on the
20th April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LAURENT
PAVIOLA, of La Ciotat, in the Empire of France, Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Laurent Paviola, Her special licence that I, the said Laurent
Paviola, my executors, administrators, and assigns, or such others as I,
the said Laurent Paviola, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and 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 ANTI-SALINE COATING CHIEFLY APPLICABLE FOR PRESERVING
FROM CORROSION AND INCRUSTATION THE BOILERS AND PIPES OF MARINE STEAM
ENGINES," upon the condition (amongst others) that I, the said Laurent
Paviola, 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 Laurent Paviola, 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 fol-
lowing statement :-
The anti-saline coating, the subject of this Invention, is chiefly applicable to
the preservation of the boilers of steam ships. It is composed of alum and of
white powder of saponaria, mixed and dissolved together in soft water, and in
equal proportions, and not only has the property of preserving the metals com-

page_text: posing the body of the boiler and its apparatus from the corrosive action of the
salt, but further (and this appears to me the most important point), that of
removing without any injury to the metal the salt coatings or incrustations
which form in the interior of the pipes, and of the body of the steam boiler.
The preparation of this anti-saline coating is as follows:-The alum is
melted in soft water in a state of ebullition, the powder of saponaria, or still
better the plant itself, is then introduced, and the boiling continued until
perfect extraction of the essence contained in the said plant, which is then
thrown away. The coating thus made may be applied with a brush, or in
any other convenient manner.
In witness whereof, I, the said Laurent Paviola, have hereunto set my
hand and seal, this Fifteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-five.
L. PAVIOLA. (L.B.)
