page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66,. Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "AN IMPROVED COMPOUND FOR COATING SHIPS
BOTTOMS AND OTHER SURFACES."-A communication from abroad by
Charles James Eames, of the City of New York, in the United States
of America.
Sealed the 26th February 1867, and dated the 20th December 1866.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on the
20th December 1866.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "AN IMPROVED COMPOUND FOR COATING SHIPS'
BOTTOMS AND OTHER SURFACES," to be as follows:-
The object of this Invention is to coat ships' bottoms and woodwork or iron
of any description, which from being exposed to the action of salt or fresh
water is liable to become foul or perforated, and thus to prevent the growth,
of vegetable matter, marine shells, and the action of worms thereon. The
composition employed for this purpose is made of asphaltum, naphtha,
carbolic acid, red oxide of mercury, and white arsenic, and mixed together in
or about the following proportions:-Asphaltum, 7 lbs.; naphtha, 4 lbs. ;
carbolic acid, 95% purity, b.; white arsenic, lb.; red oxide of mer

page_text: cury, 2 oz. The alphaltum is melted and to it is added enough naphtha to
give to the mixture the consistency of paint when cool. To this mixture,
when cool, a preparation of the remaining ingredients is added, the same
being first mixed together and ground to the consistency of paint.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office on
the 20th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Alfred Vincent Newton, Her special licence that I, the
said Alfred Vincent Newton, my executors, administrators, and assigns, or
such others as I, the Alfred Vincent Newton, 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 COMPOUND FOR COATING SHIPS' BOTTOMS AND OTHER
SURFACES," being a communication to me from abroad, upon the condition
(amongst others) that I, the said Alfred Vincent Newton, my executors or
adminstrators, 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 Vincent Newton, do hereby
declare the nature of the 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) :-
This Invention relates to the preparation of a composition which is known
as "Eames' compound paint," and is particularly intended for coating ships'
bottoms, but can be used. for coating woodwork or iron of any description;

page_text: which from being exposed to the action of salt or fresh water is liable to
become foul or perforated by worms, and the said composition is intended to
prevent the growth of vegetable matter, marine shells, and worms in the
bottom of wooden or iron vessels, and on all wood or iron substances
exposed to the action of salt or fresh water. This composition is made of
asphaltum, naphtha, carbolic acid of ninety-five per cent. purity, red oxide of
mercury, and white arsenic, and the ingredients are mixed together in or
about the following proportion:-Asphaltum, seven pounds; naphtha, four
pounds; carbolic acid, ninety-five per cent. purity, three quarters of a pound;
white arsenic, one quarter of a pound; red oxide of mercury, two ounces.
I
take the requisite quantity of asphaltum, heat the same until it is melted, and
then add enough naphtha to give to the mixture the consistency of paint
when cool; after this mixture has become cool I add a preparation of the
remaining ingredients, which are mixed together and ground to the con-
sistency of paint, and then mixed or added to the other mixture. The
preparation thus obtained I stir into the first mixture, and when both are
thoroughly mixed the composition is ready for use.
Having now set forth the nature of the Invention of "An Improved Cons-
pound for Coating Ships' Bottoms and other Surfaces," 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, a compound made of the
ingredients herein named for the purpose described, substantially as specified.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Nineteenth day of June, in the year of our
Lord One thousand eight hundred and sixty-seven.
Witness,
J. W. MOFFATT,
66, Chancery Lane.
