A NOVEL CHEMICAL COMPOSITION FOR THE PRESERVATION OF WOOD, METAL, AND OTHER SUBSTANCES
Year: 1871

page_text: LETTERS PATENT to Guillaume Alphonse Vivien, Merchant, and
Paul César Vivien, Merchant Captain, both of Honfleur, in the
Department of Calvados, in the French Republic, for the Invention
of "A NOVEL CHEMICAL COMPOSITION FOR THE PRESERVATION OF WOOD,
METAL, AND OTHER SUBSTANCES."
caled the 19th April 1872, and dated the 23rd October 1871.
PROVISIONAL SPECIFICATION left by the said Guillaume Alphonse
Vivien and Paul César Vivien at the Office of the Commissioners
of Patents, with their Petition, on the 23rd October 1871.
We, GUILLAUME ALPHONSE VIVIEN, Merchant, and PAUL CÉSAB
VIVIEN, Merchant Captain, both of Honfleur, in the Department of
Calvados, in the French Republic, do hereby declare the nature of the
said Invention for "A NOVEL CHEMICAL COMPOSITION FOR THE PRESERVATION OF
WOOD, METAL, AND OTHER SUBSTANCES," to be as follows:-
:-
The nature of this Invention consists in mixing sulphate of carbon
with the resin known as colophony.
To prepare this composition take, say, about 60 parts of sulphate of
carbon and 40 parts of colophony. Then mix the whole, that is to say,

page_text: the two parts together, at three different times, and the affinity of the
two bodies is perfect, from which results the following formula : –
CS+0=00*+*80*
Ca T3 O',
-
which forms a liquid product replacing with advantage all the com- E
positions employed hitherto for the same purposes.
This preparation is used with advantage upon wood or metal, parts of
which are in water or in the ground, as well as to coat damp buildings
before papering or painting.
Our composition is particularly applicable for coating ships' bottoms
whether of wood or iron, preserving them for an indefinite period; it
may even be applied with advantage upon copper or zinc sheathing.
Our composition may be applied to metals either before or after they
are finished for delivery to commerce in preparing them for the
manufacture for which they are intended, it is only requisite to coat
them with one or two layers of the composition, and they may then with
impunity be left exposed to damp or in water without fear of rust or
deterioration.
The preceding remarks apply equally to looking glasses, pictures, and
all articles liable to injury from damp. No looking glass will lose its
silvering if before applying the blind frame the silvering be coated with
a layer of our composition. It is the same for wood as for metals, it is
only necessary to coat them with one or two layers, and they are
instantly preserved not only against any possible decay, but further
from becoming worm eaten.
For buildings, whether of stone, brick, or plaster, all that is required
to render them healthy is to apply two coats of our preparation upon
the damp places, and neither paper or painting subsequently applied
will be injured by damp or saltpetre.
Railway engineers will find great economy in the application of this
composition to wooden railway sleepers.
We have arrived at these various results only after numerous experi-
ments and continuous research, and it will be evident that we cannot
here enumerate all the articles or products which may be preserved by
means of our composition.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Guillaume Alphonse Vivien and Paul César Vivien
in the Great Seal Patent Office on the 22nd April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GULL-
LAUME ALPHONSE VIVIEN, Merchant, and PAUL CÉSAR VIVIEN, Merchant
Captain, both of Honfleur, in the Department of Calvados, in the French
Republic, send greeting.
WHEREAS Her most Excellent Majesty, Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of October, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Guillaume Alphonse Vivien and Paul César.
Vivien, Her special licence that we, the said Guillaume Alphonse Vivien
and Paul César Vivien, our executors, administrators, and assigns, or
such others as we, the said Guillaume Alphonse Vivien and Paul César'
Vivien, our 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, excrcise, and vend within the United Kingdom of Great Britain
and Ireland, the Channel Islands and Isle of Man, an Invention for "A
NOVEL CHEMICAL COMPOSITION FOR THE PRESERVATION OF WOOD, METAL, AND
OTHER SUBSTANCES," upon the condition, amongst others, that we, the said
Guillaume Alphonse Vivien and Paul César Vivièn, our executors or
administrators, by an instrument in writing under our, 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 we, the said Guillaume Alphouse Vivien and
Paul César Vivien, do hereby declare the nature of our said Invention
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The nature of this Invention consists in mixing sulphate of carbon
with the resin known as colophony.
To prepare this composition take, say, about 60 parts of sulphate of

page_text: carbon and 40 parts of colophony. Then mix the whole, that is to say,
the two parts together, at three different times, and the affinity of the
two bodies is perfect, from which results the following formula :—
which forms a liquid product replacing with advantage all the com-
positions employed hitherto for the same purposes.
This preparation is used with advantage upon wood or metal, parts of
which are in water or in the ground, as well as to coat damp buildings
before papering or painting.
Our composition is particularly applicable for coating ships' bottoms
whether of wood or iron, preserving them for an indefinite period; it may
even be applied with advantage upon copper or zinc sheathing.
Our composition may be applied to metals either before or after they.
are finished for delivery to commerce, or in preparing them for the
manufacture for which they are intended; it is only requisite to coat
them with one or two layers of the composition, and they may then_
with impunity be left exposed to damp or in water without fear of rust
or deterioration.
The preceding remarks apply equally to looking glasses, pictures,
and all articles liable to injury from damp. No looking glass will lose
its silvering if before applying the blind frame the silvering be coated
with a layer of our composition. It is the same for wood as for metals,
it is only necessary to coat them with one or two layers, and they are
instantly preserved not only against any possible decay, but further,
from becoming worm caten.
For buildings, whether of stone, brick, or plaster, all that is required
to render them healthy is to apply two coats of our preparation upon
the damp places, and neither paper or painting subsequently applied will
be injured by damp or saltpetre.
Railway engineers will find great economy in the application of this
composition to wooden railway sleepers.
We have arrived at these various results only after numerous experi-
ments and continuous research, and it will be evident that we cannot
here enumerate all the articles or products which may be preserved by
means of our composition.

page_text: Having now described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we would have it
understood that we do not limit ourselves to any exact proportion of the
components of our preparation, that the proportions above given are
only approximative, and will vary with the quality of the ingredients
and other considerations, and that we claim the within described com-
position or coating compounded of the ingredients specified, substan-
tially as and for the purposes set forth.
In witness whereof, we, the said Guillaume Alphonse Vivien and
Paul César Vivien, have hereunto set our hands and scals, this
Thirtieth day of March, in the year of our Lord One thousand
eight hundred and seventy-two.
