Year: 1863

page_text: LETTERS PATENT to Thomas Simmelkiar, of Blackrock, in the County
of Cork, Ireland, and John Ibbetson Spicer, of Park Road, Old Ford,
in the County of Middlesex, for the Invention of "AN IMPROVED COX-
POSITION FOR COATING OR PAINTING THE BOTTOMS OF SHIPS OR VESSELS TO
PREVENT THEM FROM FOULING."
Sealed the 2nd February 1864, and dated the 6th August 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Simmelkiar and
John Ibbetson Spicer, at the Office of the Commissioners of Patents,
with their Petition on the 6th August 1863.
We, THOMAS SIMMELKIAR, of Blackrock, in the County of Cork, Ire-
land, and JOHN IBBETSON SPICER, of Park Road, Old Ford, in the County
of Middlesex, do hereby declare the nature of the Invention for "Ar
IMPROVED COMPOSITION FOR COATING OR PAINTING THE BOTTOMS OF SHIPS OB
VESSELS TO PREVENT THEM FROM FOULING," to be as follows:-
This Invention consists in making a composition suitable for coating or
painting the bottoms of ships or vessels to prevent them from becoming foul
by the adhesion thereto of barnacles, seaweed, or other matters which
accumulate thereon, and retard the speed of the vessel when not so protected.
For this purpose we combine by boiling guano (by preference the best
Peruvian) with (by preference) boiled oil in the proportion of about twenty
pounds of guano to 1 gallon of oil. After boiling together for about a quarter
of an hour (more or less) we gradually stir in twenty-two pounds or thereabouts
of red lead, after which we add a few pounds of white lead. We then grind
the whole of these materials together, forming them into a paint by the
addition of oil if required, to which any suitable "dryer" may be added to

page_text: cause each coat when laid on to dry quickly if desired. We prefer to apply
two coats of this composition in order to protect the bottoms of the vessels to
which it is applied. We would remark that this composition is particularly
applicable for protecting the bottoms of iron ships or vessels from "fouling,"
and also for preserving the zinc or other metal sheathing of ships or vessels
when applied thereto for this purposo.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Simmelkiar and John Ibbetson Spicer in the
Great Seal Patent Office on the 5th February 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
SIMMELKIAR, of Blackrock, in the County of Cork, Ireland, and JOHN IBBET-
SON SPICER, of Park Road, Old Ford, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of August, 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 us,
the said Thomas Simmelkiar and John Ibbetson Spicer, Her special licence
that we, the said Thomas Simmelkiar and John Ibbetson Spicer, our
executors, administrators, and assigns, or such others as we, the said
Thomas Simmelkiar and John Ibbetson Spicer, our executors adminis-
trators, 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 "AN IMPROVED COMPOSITION FOR COATING OR PAINTING
THE BOTTOMS OF SHIPS OR VESSELS, TO PREVENT THEM FROM FOULING," upon the
condition (amongst others) that we, the said Thomas Simmelkiar and John
Ibbetson Spicer, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of
us or them, 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 John Ibbotson Spicer, on behalf of
myself and the said Thomas Simmelkiar, do hereby declare the nature of the
said Invention, and in what manner the same is to be performed, to be

page_text: particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention consists in making a composition suitable for coating or
painting the bottoms of ships or vessels to prevent them from becoming foul
by the adhesion thereto of barnacles, seaweed, or other matters which
accumulate thereon, and retard the speed of the vessel when not so protected.
For this purposo we combine by boiling guano (by preference the best
Peruvian) with oil, by preference boiled, in the proportion of about twenty
pounds of guano to one gallon of oil. After boiling together for about a quarter
of an hour (more or less), we gradually stir in twenty-two pounds or there-
abouts of red lead, after which we add a few pounds of white lead. We then
grind the whole of these materials together, forming them into a paint by the
addition of oil if required, to which any suitable "dryer" may be added to
cause each coat when laid on to dry quickly if desired. We prefer to apply
two coats of this composition, in order to protect the bottoms of the vessels
vessels to which it is applied. We would remark that this composition is
particularly applicable for protecting the bottoms of iron ships or vessels from
"fouling," and also for preserving the zinc or other metal sheathing of ships
or vessels when applied thereto for this purpose.
Having thus described the nature of our Invention, we would have it
understood that we do not confine ourselves to the exact details herein men-
tioned, so long as the peculiar character thereof be retained, but what wo
claim is the making of a composition composed chiefly of guano, combined
with other ingredients as herein described, for the purpose of coating or paint-
ing the bottoms of ships or vessels in order to prevent them from fouling, and
to preserve the zinc or other metal sheathing from corrosion, oxidation, or
decay.
In witness whereof, I, the said John Ibbetson Spicer, have hereunto
set my hand and seal, this Fourth day of February, in the year of
Witness,
