Year: 1855

page_text: LETTERS PATENT to Joseph Westwood, of Poplar, in the County of
Middlesex, Tron Ship Builder, and Robert Baillic, also of Poplar, in the
County of Middlesex, Iron Ship Builder, for the Invention of "IMPROVE-
MENTS IN PRESERVING TIMBER-BUILT SHIPS, ALSO TIMBER OR WOOD AND
WROUGHT IRON USED IN SITUATIONS EXPOSED TO THE ACTION OF WATER OR OF
WEATHER."
Sealed the 12th January 1856, and dated the 24th July 1855.
PROVISIONAL SPECIFICATION left by the said Joseph Westwood and
Robert Baillie at the Office of the Commissioners of Patents, with their
Petition, on the 24th July 1855.
We, JOSEPH WESTWOOD, of Poplar, in the County of Middlesex, Iron Ship
Builder, and ROBERT BAILLIE, also of Poplar, in the County of Middlesex,
Iron Ship Builder, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PRESERVING TIMBER-BUILT SHIPS, ALSO TIMBER OR WOOD AND
WROUGHT IRON USED IN SITUATIONS EXPOSED TO THE ACTION OF WATER OR OF
WEATHER," to be as follows :-
Our Invention has reference to the preservation of timber ship's wood,
piles, planking, or other timber or wood used in the construction of piers,

page_text: docks, wharfs, or foundations, also for railway sleepers, telegraph poles, tensing
posts, and other similar purposes. It likewise has reference to the preservation
of wrought-iron plates, girders, bolts, and other wrought-iron work used in the
construction of roofs, bridges, piers, docks, and other similar structures.
And our Invention consists in applying to the wood or iron used for such
purposes a preparatory coating of black varnish, or other composition having
similar properties thereto, and afterwards a coating of asphalte or bituminous
composition, whereby the latter will be made to adhere with increased tenacity
to the surface to which it is applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Westwood and Robert Baillie in the Great Seal
Patent Office on the 12th January 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPII
WESTWOOD, of Poplar, in the County of Middlesex, Iron Ship Builder, and
ROBERT BAILLIE, also of Poplar, in the County of Middlesex, Iron Ship
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of July, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Joseph Westwood and Robert Baillic, Her special license that we, the
said Joseph Westwood and Robert Baillie, our exccutors, administrators, and
assigns, or such others as we, the said Joseph Westwood and Robert Baillie,
our 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 IMPROVEMENTS IN PRESERVING
TIMBER-BUILT SHIPS, ALSO TIMBER OR WOOD AND WROUGHT IRON USED IN SITUATIONS
EXPOSED TO THE ACTION OF WATER OR OF WEATHER," upon the condition (amongst
others) that we, the said Joseph Westwood and Robert Baillie, by an instru-
ment in writing under our hands and seals, or under the hand and seal of
one of us, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the

page_text: 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 we, the said Joseph Westwood and Robert Baillie,
do hereby declare the nature of our 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):-
Our Invention of " Improvements in Preserving Timber-built Ships, also
Timber or Wood and Wrought Iron used in Situations exposed to the Action
of Water or of Weather," has reference to the preservation of timber ship's
wood, piles, planking, or other timber or wood used in the construction of
piers, docks, wharfs, or foundations; also for railway sleepers, telegraph poles,
It likewise has reference to the
tensing posts, and other similar purposes.
preservation of wrought-iron plates, girders, bolts, and other wrought-iron
work used in the construction of roofs, bridges, piers, docks, and other similar
structures.
And our Invention consists in applying to the wood or iron used for such
purposes a preparatory coating of black varnish, or other composition having
similar properties thereto, and afterwards a coating of asphalte or bituminous
composition, whereby the latter will be made to adhere with increased tenacity
to the surface to which it is applied.
The manner in which we apply the said coatings to the surfaces intended to
be protected by them is as follows:-We first pay on the varnish composition
with a paint brush, and afterwards we pour on the melted asphalte or bitumen
on the surface of the wood or metal; or we immerse the wood or metal
to be preserved in the melted asphalte or bitumen; or we take a brush and
it over the surface.
pay
Having thus described the nature of our Invention, and in what manner the
same is to be performed, we would have it understood that we do not intend
to confine ourselves to the mode described of applying the above compositions;
neither do we claim as of our Invention any precise proportions in the ingre-
dients used in the manufacture of the black varnish or other composition
intended to form the preparatory coating for the wood or iron; neither do we
claim as of our Invention any particular mode of manufacturing the asphalte or
bituminous composition intended to form the subsequent coating for the wood
or iron; and we have not thought it necessary to describe the manufacture
of such compositions, as they are well known, being used separately for various
purposes. But we declare that we claim as of our Invention, the application to
timber-built ships, and to wood and wrought iron used for the purposes above

page_text: referred to, of a preparatory coating and a subsequent coating of the compo-
sitions respectively, as described.
In witness whereof, we, the said Joseph Westwood and Robert Baillie,
have hereunto set our hands and seals, the Twenty-second day of
December, in the year of our Lord One thousand eight hundred and
fifty-five.
