page_text: LETTERS PATENT to James Robert Casbay, of Newman Street,
Oxford Street, in the County of Middlesex, Chemist, for the In-
vention of "AN IMPROVED COMPOUND TO BE APPLIED TO THE SURFACES OF
WOOD OR METAL TO PRESERVE THE SAME FROM CORROSION OR DECAY."
Sealed the 3rd January 1873, and dated the 11th July 1872.
PROVISIONAL SPECIFICATION left by the said James Robert Casbay
at the Office of the Commissioners of Patents, with his Petition,
on the 11th July 1872.
I, JAMES ROBERT CASBAY, of Newman Street, Oxford Street, in the
County of Middlesex, Chemist, do hereby declare the nature of the
said Invention for "AN IMPROVED COMPOUND TO BE APPLIED TO THE SURFACES
OF WOOD OR METAL TO PRESERVE THE SAME FROM CORROSION OB DECAY," to be
as follows:-
My said invention relates to a compound or composition which when
properly applied to the surfaces of wood or metal will effectually preserve
the same from the destructive action of salt or other water, the attacks

page_text: of marine insects or animals, the growth or deposit of vegetable or other
substances, the effects of moisture or exposure to the atmosphere, and
from other similar destructive agencies.
The said compound may be advantageously employed for coating or
covering wood or iron ships, the wood or ironwork of piers, bridges, &
docks, and other like structures, buoys, chains, and other articles exposed
to the above-named or other similar destructive influences.
The said compound consists of cressol, phenol, or carbolic acid,
or phenol-alcohol in a neutral or acid form, or in a hydrated or
dyhydrated form, mixed with pitch, resin, or bituminous or silicic 1
varnish or paint, in such proportion as will give the compound about
the consistency of ordinary paint or varnish. For some purposes I also
mix with the above compound metallic soap, mercury, arsenic, copper,
or other metal.
The said compound is applied to the surface to be covered, either hot 1
or cold, and with a brush, or in any other ordinary or convenient manner
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Robert Casbay, in the Great Seal Patent
Office on the 11th January 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
ROBERT CASBAY, of Newman Street, Oxford Street, in the County of
Middlesex, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of July, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Robert Casbay, Her special
licence that I, the said James Robert Casbay, my executors, adminis-
trators, and assigns, or such others as I, the said James Robert Casbay,
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

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
" AN IMPROVED COMPOUND TO BE APPLIED TO THE SURFACES OF WOOD OR METAL
TO PRESERVE THE SAME FROM CORROSION OR DECAY," upon the condition
. (amongst others) that I, the said James Robert Casbay, 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 James Robert Casbay, 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 :—
My said Invention relates to a compound or composition, which when
properly applied to the surface of wood or metal will effectually preserve
the same from the destructive action of salt or other water, the attack
of marine insects or animalculae, the growth or deposit of vegetable or
other substances, the effects of moisture or exposure to the atmosphere,
and from other similar destructive agencies.
The said compound may be advantageously employed for coating or
covering wood or iron ships, the wood or ironwork of piers, bridges,
docks, and other like structures, and buoys, chains, and other similar
articles exposed to the above-named or other similar destructive
influences. It will also afford protection to the surfaces of stone,
brick, plaster, and other like materials.
The said compound consists of oressol, phenol, or carbolic acid, or
phenol-alcohol or kreosote, in a neutral, acid, or alkaline form, and in a
hydrated or dihydrated form, mixed with pitch, resin, or bituminous
silica or alumina varnish, or other suitable varnish, paint, or size, and in
such proportions as may be required to render it protective against insects,
vegetable growths, gases, damp, and other destructive agencies. I prefer
to use such proportion as will give the compound about the consistency
of ordinary paint or varnish.
I may use the phenol or other substances in a crude form, or I may

page_text: other foreign matter. Or I may mix with the phenol or other substances
about an equal quantity of naphtha, which will separate from the phenol
or other substance any water that may be held in solution.
I also mix with the above compound metallic soap, mercury, arsenic,
copper, or other metal or metallic oxide salt.
The said compound is applied to the surface to be covered, either hot
or cold, and with a brush, or in any other ordinary or convenient manner
of applying paint or varnish.
Having thus fully described the said Invention, and the manner of
performing the same, I wish it understood that I claim,—
The herein-described compound of cressol, phenol, or carbolic acid,
phenic-alcohol kreosote, or any of their derivatives mixed with varnish,
or any similar suitable substance, and either with or without the
metals, metallic oxide salts, or metallic soap, as herein set forth.
In witness whereof, I, the said James Robert Casbay, have here-
unto set my band and seal, this Ninth day of January, in the
year of our Lord One thousand eight hundred and seventy-three.
Witness,
JAMES ROBERT CASBAY. (L.S.)
