page_text: LETTERS PATENT to Alfred Borgnet, of Swansea, in the County of
Glamorgan, South Wales, Manufacturer, for the Invention of "AN
IMPROVED COMPOSITION TO BE EMPLOYED AS A PAINT."
IMPROVED COMPOSITION TO BE EMPLOYED AS A PAINT."
Sealed the 7th September 1869, and dated the 22nd April 1869.
PROVISIONAL SPECIFICATION left by the said Alfred Borgnet at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd April 1869.
I, ALFRED BORGNET, of Swansea, in the County of Glamorgan, South
Wales, Manufacturer, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED COMPOSITION TO BE EMPLOYED AS A PAINT," to be as
follows:-
This Invention may be applied in the form of a paint or varnish, and
being to a considerable extent impervious to water I propose to apply
it to wood, metal, and other surfaces requiring protection from moisture.

The metallic base which I employ in the manufacture of the com-
position consists of globular zinc or grey oxide, otherwise known as
sweeps," and which is a product obtained in the smelting of zinc ores.
This substance, in the form of an impalpable powder, I mix with boiled
linseed oil in the proportion of sixty-six parts by weight of the grey
oxide to twenty parts of the boiled oil. These substances intimately
commingled make mixture No. 1.
I also make a siccative mixture by treating raw linseed oil in the
following manner:-I take oxide of manganese (in the natural state),
say, one part, and having broken it up to about the size of small peas
I boil it in, say, four parts by weight of the raw linseed oil in an open
vessel until the desired consistency is obtained. The manganese I
enclose in a strong linen bag and insert the bag in a basket or perforated.
vessel of iron that will allow of the raw linseed oil coming into. contact
with the oxide of manganese through the bag. This basket I suspend
in the oil so that it shall not touch the vessel containing it and when the
boiling is stopped I remove the basket and its contents. from the vessel..
By this treatment I obtain mixture No. 2.
For a third mixture I dissolve india-rubber or other equivalent
vegetable gum in turpentine or other suitable solvent, the proportions
being, say, two parts of the gum to seven parts of turpentine or other
solvent.
Of these several mixtures I take, say, eighty-six parts of No. 1, five
parts of No. 2, and nine parts of No. 3, and combine the same by
stirring or by any other means while cold, and when completely com-
bined a liquid compound is formed, which I pack in barrels or iron kegs
ready for use. If not liquid enough oil or oils may be added until
the proper consistency is obtained. The composition may be applied
like ordinary paint to the surface to be protected, and it will when dry
impart somewhat of an enamelled appearance to the coated surface.
When the composition is intended for coating ships' bottoms I may
find it desirable to add thereto an extract of aloes, which is a strong
repellent to animal life.

filed by the said Alfred Borgnet in the Great Seal Patent Office
on the 22nd October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
BORGNET, of Swansea, in the County of Glamorgan, South Wales,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of April, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Alfred Borgnet, Her special
licence that I, the said Alfred Borgnet, my executors, administrators,
and assigns, or such others as I, the said Alfred Borgnet, 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
COMPOSITION TO BE EMPLOYED AS A PAINT," upon the condition (amongst
others) that I, the said Alfred Borgnet, 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 Alfred Borgnet, 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 (that is to say) :-
:-
The chief object of this Invention is to protect ships' bottoms from
the adhesion thereto of marine, animal, and vegetable life by the
employment of a composition that may be applied in the form of a
paint or varnish. This composition being to a considerable extent

page_text: impervious to water I also propose to apply it to wood, metal, and other
surfaces requiring protection from moisture.
The metallic base which I employ in the manufacture of my improved
composition or paint consists of globular zinc or grey oxide, otherwise
known as "sweeps," and which is a product obtained in the smelting
of zinc ores. This substance, in the form of an impalpable powder, I
mix with boiled linseed oil in the proportion of sixty-six parts by weight
of the grey oxide to twenty parts of the boiled oil. These substances.
intimately commingled make mixture No. 1.
I also make a siccative mixture by treating raw linseed oil in the
following manner:-I take oxide of manganese (in the natural state),
say, one part, and having broken it up to about the size of small peas
I boil it in, say, four parts by weight of the raw linseed oil in an open
vessel until the desired consistency is obtained. The manganese I
enclose in a strong linen bag, and insert the bag in a basket or per-
forated vessel of iron that will allow of the raw linseed oil coming into
contact with the oxide of manganese through the bag. This basket I
suspend in the oil so that it shall not touch the vessel containing it,
and when the boiling is stopped I remove the basket and its contents
from the vessel. By this treatment I obtain mixture No. 2.
For a third mixture I dissolve india-rubber or other equivalent
vegetable gum in turpentine or other suitable solvent, the proportions
being, say, two parts of the gum to seven parts of turpentine or other
solvent.
Of these several mixtures I take, say, eighty-six parts of No. 1,
five parts of No. 2, and nine parts of No. 3, and combine the same
by stirring or by any other proper means while cold, and when com-
pletely combined a liquid compound is formed suitable for the purposes
of this Invention. The liquid compound I pack in barrels or iron kegs,
in which it may be kept ready for use. If not sufficiently thin for
application to the surface intended to be coated oil or oils may be added
until the proper consistency is obtained. The composition may be
applied like ordinary paint to the surface to be protected, and it will,
when dry, impart somewhat of an enamelled appearance to the coated
surface. When the composition is intended for coating ships' bottoms
I may find it desirable to add thereto an extract of aloes, which is a
strong repellent to animal life.

page_text: Composition to be Employed as a Paint," and explained the manner of
carrying the same into effect, I wish it to be understood that under
the above in part recited Letters Patent I claim, manufacturing a
composition or paint in the manner and for the purpose above set
forth.
In witness whereof, I, the said Alfred Borgnet, have hereunto set
my hand and seal, the Nineteenth day of October, in the year
of our Lord One thousand eight hundred and sixty-nine.
