Year: 1863

page_text: LETTERS PATENT to Marius Vian, of Marseilles, in the Empire of
France, Ship Builder, for the Invention of "CERTAIN COMPOSITIONS FOR
PRESERVING IRON SHIPS AND OTHER SUBMERGED IRONWORK FROM CORROSION
AND FROM FOULING."
Sealed the 15th April 1864, and dated the 26th October 1863.
PROVISIONAL SPECIFICATION left by the said Marius Vian at the
Office of the Commissioners of Patents, with his Petition, on the
26th October 1863.
J, MARIUS VIAN, of Marseilles, in the Empire of France, Ship Builder, do
hereby declare the nature of the said Invention for "CERTAIN COMPOSITIONS FOR
PRESERVING IRON SHIPS AND OTHER SUBMERGED IRONWORK FROM CORROSION AND
FROM FOULING," to be as follows:-
I first mix together about 1½ lbs. of yellow or unbleached wax, 13 lbs. of
essence of turpentine, and 3 lbs. of linseed oil, containing about 10 per cent. of
manganese. To a pound of this mixture or composition I add a pound of
zinc white, and apply one, two, or more coatings of the paint thus obtained to
the iron surface to be preserved. To obtain a composition of the consistence
of cement I mix a pound of the first mixture or composition with a pound and
a half of zinc white, and add 30 per cent. of arsenious acid, or 10 per cent.
of binoxide of mercury, and 20 per cent. of arsenious acid. The proportions
before given may be considerably varied.

by the said Marius Vian in the Great Seal Patent Office on the
25th April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARIUS
VIAN, of Marseilles, in the Empire of France, Ship Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of October, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Marius Vian, Her special licence that I, the said
Marius Vian, my executors, administrators, and assigns, or such others as
I, the said Marius Vian, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "CERTAIN
COMPOSITIONS FOR PRESERVING IRON SHIPS AND OTHER SUBMERGED IRONWORK
FROM CORROSION AND DECAY," upon the condition (amongst others) that I, the
said Marius Vian, 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 Marius Vian, do hereby declare the
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:-
This Invention relates to an improved fero-manganic mixture for preserving
surfaces of iron exposed to the action of water by preventing oxidization and
adhesion of weeds, animalcules, and other substances. In the first place two
coatings of the following paint are given to the whole surface to be protected.
This paint is composed as follows:-I take seven 7 parts of yellow wax; sixty
60 parts of essence of turpentine; seventeen 17 parts of oil saturated with
manganese in the proportion of 10 per cent. Total eighty-four 84 parts of
oil mixture. To make up the paint I take, one 1 part of oil mixture, one 1
part of white lead; forming two 2 parts of liquid paint, having a light yellow
tint.

page_text: Here it is important to mention that the wax is melted separately, and then
mixed with the oil saturated with manganese and the essence of turpentine
and well stirred. I recommend the exact quantities above given. The final
operation consists in spreading with a trowel over the coatings of paint a sort
of putty. This putty I make as follows, I take ten 10 parts of oil mixture;
fifteen 15 parts of white lead. To this mixture I add fifteen 15 per cent. of
by-oxide of mercury, and fifteen 15 per cent. of arsenic acid; or simply with
twenty 20 per cent. of by-oxide of mercury. Any required tint may be given
to the composition by adding a small quantity of colour; but a grey tint is
preferred as being easily distinguished from the paint already spread, and thus
preventing unpainted spaces being left on the iron. This grey colour is
obtained by adding a little black to the putty composition.
Having thus described the nature of the said Invention, what I claim is
preserving hulls of iron ships, and other submerged iron surfaces, by the
means above described, whatever colour may be given to the paint or putty.
In witness whereof, I, the said Marius Vian, have hereunto set my hand
and seal, this Twenty-third day of April, in the year of our Lord One
thousand eight hundred and sixty-four.
MRIUS. VIAN. (L.S.)
