Year: 1870

page_text: LETTERS PATENT to Achille Thomas-Anquetil, of Boulevard de
Strasbourg, No. 23, Paris, France, for the Invention of "AN IM-
PROVED TREATMENT AND APPLICATION OF OLEIC AND STEARIC ACIDS FOR
PROTECTING METALLIC SURFACES FROM OXIDATION, AND PRESERVING WOOD
AND OTHER MATERIALS."
Sealed the 24th September 1870, and dated the 4th April 1870.
PROVISIONAL SPECIFICATION left by the said Achille Thomas-Anquetil
at the Office of the Commissioners of Patents, with his Petition, on
the 4th April 1870.
I, ACHILLE THOMAS-ANQUETIL, of Boulevard de Strasbourg, No. 23,
Paris, France, do hereby declare the nature of the said Invention for
"AN IMPROVED TREATMENT AND APPLICATION OF OLEIC AND STEARIC ACIDS FOR
PROTECTING METALLIC SURFACES FROM OXIDATION, AND PRESERVING WOOD AND
OTHER MATERIALS," to be as follows:-
:—
The object of my Invention is a new method of treating oleic and
stearic acids in order to obtain a composition which I call “Thomassine
,,

page_text: for use as a pigment, glaze, coating, or varnish, or polish, either in a
hot or cold state, and which may be applied by the brush like an
ordinary pigment upon any surface or object. Olcic and stearic acid
treated according to this Invention may also be employed to lubricate
the parts of machines.
This Invention consists in the following process:-Oleic or stearic
acid are treated upon an open fire in an uncovered vessel. When the
inflammable substances are evaporated and the superabundant fatty
matters have been burned (which will be when the flame of the liquid
expires of itself, or when the vapours are no longer very heavy and
odorous) the oleaginous liquid is filtered in the ordinary way. It is
then again filtered through charcoal, animal black, chlorate of potash,
or other matters which will absorb the acid particles which it may still
contain. The product from this second filtration is a fatty liquid,
resembling oil, and is suitable for the base of paints, coatings, stuccoes,
glazes, enamels, varnishes, and all other similar materials. The com-
position is applied by the brush, and it may be thickened or thinned at
pleasure like ordinary paint. One or more coatings of it may be applied
according to the effect desired to be produced. In order to more
perfectly fix the composition upon metals, glass, pottery, earthenware,
or leather, the objects are passed once or twice through a furnace or
stove after the application of one or two coatings.
Varnishes, by way of polish for different sorts of wood, furniture,
wainscoatings, panels, and other purposes, are produced by raising by
means of a rough cloth the coating of paint upon the material, and then
rubbing it with a soft cloth or piece of wool dipped in alcohol. This
composition may also be made to adhere to objects made of india-rubber
by the previous application of a known preparation called mixtion.
This composition has the remarkable property of protecting the objects
which are coated by it from the oxidation, decomposition, and decay
produced by atmospheric and other causes, and also of rendering them
almost incombustible and indelible.
I have successfully used the composition with wood, grit stone, rubble
stone, mortar, plaster, cement, slate, tiles, bricks, pottery, and earthen-
ware, cast iron, iron, tin, steel, lead, bronze, pewter, nickel, gold, silver,
platina, vitreous compositions; the quicksilvering of mirrors, leather,
india-rubber, conducting pipes, iron and copper wire ropes, and a great
number of other materials.

page_text: The composition also possesses the advantage of permitting the
employment as colouring agents in painting of the earths of umber,
sienna, and others; of lacs, ochres, tales, sulphate of baryta, the different
bronze powders, and others to replace those substances, the employment
and preparation of which are injurious, as ceruse, minium, litharge,
chromate of lead, and such like, and that with great economy and
facility.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Achille Thomas-Anquetil in the Great Seal Patent
Oflice on the 1th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ACHILLE
THOMAS-ANQUETIL, of Boulevard de Strasbourg, No. 23, Paris, France,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Ierself, Her heirs and successors, give and
grant unto me, the said Achille Thomas-Anquetil, Her special licence
that I, the said Achille Thomas-Anquetil, my executors, administrators,
and assigns, or such others as I, the said Achille Thomas-Anquetil, 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
TREATMENT AND APPLICATION OF OLEIC AND STEARIC ACIDS FOR PROTECTING
METALLIC SURFACES FROM OXIDATION, AND PRESERVING WOOD AND OTHER MA-
TERIALS," upon the condition (amongst others) that I, the said Achille
Thomas-Anquetil, 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

page_text: 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 Achille Thomas-Anquetil, 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 following statement thereof, that is to say :-
"3
The object of my Invention is a new method of treating oleic and
stearic acids in order to obtain a composition which I call "Thomassine
for use as a pigment, glaze, coating, varnish, or polish, either in a hot
or cold state, and which may be applied by the brush like an ordinary
pigment upon any surface or object. Olcic and stearic acid treated
according to this Invention may also be employed to lubricate the parts

inflammable substances are evaporated and the superabundant fatty
matters have been burned (which will be when the flame of the liquid
expires of itself, or when the vapours are no longer very heavy and
odorous), the oleaginous liquid is filtered in the ordinary way. It is
then again filtered through charcoal, animal black, chlorate of potash,
or other matters which will absorb the acid particles which it may still
oontain. The product from this second filtration is a fatty liquid
resembling oil, and is suitable for the base of paints, coatings, stuccoes,
glazes, enamels, varnishes, and all other similar materials. The com-
position is applied by the brush, and it may be thickened or thinned at
pleasure like ordinary paint. One or more coatings of it may be applied
according to the effect desired to be produced. In order to moro
perfectly fix the composition upon metals, glass, pottery, carthenware,
or leather, the objects are passed once or twice through a furnace or
stove after the application of one or two coatings.
Varnishes by way of polish for different sorts of wood, furniture,
wainscoatings, panels, and other purposes are produced by raising by
means of a rough cloth the coating of paint upon the material, and then
rubbing it with a soft cloth or piece of wool dipped in alcohol. This
composition may also be made to adhere to objects made of india-rubber
by the previous application of a known preparation called "mixtion."
This composition has the remarkable property of protecting the objects
which are coated by it from the oxidation, decomposition, and decay

page_text: produced by atmospheric or other causes, and also of rendering them
almost incombustible and indelible.
I have successfully used the composition with wood, gritstone, rubble-
stone, mortar, plaster, cement, slate, tiles, bricks, pottery, and carthen-
ware, cast iron, iron, tin, steel, lead, bronze, pewter, nickel, gold, silver,
platina, vitreous compositions; the quicksilvering of mirrors, leather,
india-rubber, conducting pipes, iron and copper wire ropes, and a great
number of other materials.
The composition also possesses the advantage of permitting the
employment as colouring agents in painting of the earths of umber,
sienna, and others; of lacs, ochres, tales, sulphate of baryta, the different
bronze powders and others to replace those substances, the employment
and preparation of which are injurious, as ceruse, minium, litharge,
chromate of lead, and such like, and that with great economy and
facility.
And, lastly, oleic and stearic acids treated as above and transformed
into the composition called "Thomassine" possess the property of being
suitable for serving as a lubricating agent for the parts of machinery.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,―
Firstly. Treating oleic and stearic acids as hercin-before described in
order to obtain the new substance hercin-before called "Thomassinc."
Secondly. Mixing the said substance or Thomassine with the earths
of umber, sienna, and others, and with ochres, tales, sulphate of baryta,
bronze powders, and other substances in substitution for ceruse, minium,
litharge, and other substances before used, in order to form a protective
coating for wood and other surfaces.
And, thirdly. The employment of the said substance or Thomassine as
a lubricant for machinery.
In witness whereof, I, the said Achille Thomas-Anquetil, have
hereunto set my hand and scal, this Third day of October One
thousand eight hundred and seventy.
