page_text: LETTERS PATENT to James Ballantyne Hannay, of Glasgow, in the County of
Lanark, North Britain, for an Invention of "A NEW OR IMPROVED ANTI-
FOULING AND ANTI-CORROSION COMPOUND OR MIXTURE APPLICABLE FOR
PREVENTING THE FOULING OF SHIPS' BOTTOMS AND OTHER SUBMERGED
STRUCTURES, AND GENERALLY FOR THE PROTECTION OF METAL, STONE, WOOD,
OR OTHER SURFACES."
PROVISIONAL SPECIFICATION left by the said James Ballantyne Hannay
at the Office of the Commissioners of Patents on the 21st February 1880.
JAMES BALLANTYNE HANNAY, of Glasgow, in the County of Lanark, North
Britain. "A NEW OR IMPROVED ANTI-FOULING AND ANTI-CORROSION COMPOUND
OR MIXTURE APPLICABLE FOR PREVENTING THE FOULING OF SHIPS' BOTTOMS AND
OTHER SUBMERGED STRUCTURES, AND GENERALLY FOR THE PROTECTION OF METAL,
STONE, WOOD, OR OTHER SURFACES."
The said Invention relates to a new or improved anti-fouling and anti-corrosion
compound or mixture applicable for preventing the fouling of ships' bottoms and
other submerged structures, and generally for the protection of metal, stone, wood,
or other surfaces. The said compound or mixture is composed of naptha, colophony,
soft turpentine, and linseed oil, to which any desired colouring matter may be added
to fit it for use as a paint. When the compound or mixture is to be used for anti-
fouling purposes arsenite of mercury and basic chromate of mercury (mercurouR
and mercuric salts), both or either, are to be added. Proportions which I have
found to answer well are.—

but these proportions may be varied. When mercury compounds are used in
manufacturing the anti-fouling composition they may be added in a proportion ⚫
of 12 to 20 per cent. (or thereabouts) of the compound.
The colophony, turpentine, and oil may be put into a tank containing the
naptha and the whole incorporated by stirring. The compound or mixture may
be applied to the surface to be protected in the ordinary manner of applying
paint.
Arsenite of copper may be used in place of the whole or part of the mercury
compounds, but I prefer the latter.

the said James Ballantyne Hannay in the Great Seal Patent Office on the
21st August 1880.

Britain. "A NEW OR IMPROVED ANTI-FOULING AND ANTI-CORROSION COMPOUND
OR MIXTURE APPLICABLE FOR PREVENTING THE FOULING OF SHIPS' BOTTOMS AND
OTHER SUBMERGED STRUCTURES, AND GENERALLY FOR THE PROTECTION OF METAL,

My said Invention relates to a new or improved anti-fouling and anti-corrosion
compound or nixture applicable for preventing the fouling of ships' bottoms and
other submerged structures, and generally for the protection of metal, stone, wood,
or other surfaces. The said compound or mixture is composed of naptha, colo-
phony, soft turpentine, and linseed oil, to which any desired colouring matter may
be added to fit it for use as a paint to protect surfaces from corrosion. When the
compound or mixture is to be used for anti-fouling purposes arsenites of mercury
and basic chromates of mercury (mercurous and mercuric salts), both or either, are
to be added. Proportions which I have found to answer well for the anti-corrosion
compound are.

The colophony, turpentine, and oil may be put into a tank containing the
naptha and the whole incorporated by stirring, and a colouring medium may
be added so that the anti-corrosion compound may be fitted for use as a paint.
The compound or mixture may be applied to the surface to be protected in the
ordinary manner of applying paint.
When mercury compounds are used in manufacturing the anti-fouling com-
position they may be added in a proportion of 12 to 20 per cent. (or thereabouts)
of the compound, the said mercury compounds being thoroughly incorporated by
stirring or otherwise.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner, in or under which the same is or may
be used, or practically carried into effect, I would observe in conclusion that what
1 consider to be novel and original, and therefore claim as the Invention secured
to me by the heroinbefore in part recited Letters Patent is,―
First. The herein before described compound, consisting of naptha, colophony, soft
turpentine, and linseed oil for protecting surfaces from corrosion.
Second. The herein before described anti-fouling compound, consisting of the
herein before described anti-corrosion compound (claimed in the preceding clause)
with the addition of arsenites or chromates of mercury, both or either of them.
In witness whereof, I, the said James Ballantyne Hannay, have hereunto set
my band and seal, this Twentieth day of August, in the year of our Lord
One thousand eight hundred and eighty.
