Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
JEFFERY, of Brunton Works, Limehouse, in the County of Middlesex, Gen-
tleman, send greeting.
WHEREAS Her present most Excellent Majesty hath granted unto me
Her Letters Patent, bearing date at Westminster, the Nineteenth day of
February, in the seventh year of Her reign, for making, using, exercising, and
vending, within that part of the United Kingdom of Great Britain and
Ireland called England, Her Dominion of Wales, and Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN TREATING WOOD AND CER-
TAIN OTHER SUBSTANCES REQUIRING TO BE EXPOSED TO WATER," subject to the
usual proviso, obliging me to particularly describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, and to cause the same to be
inrolled in the High Court of Chancery within six calendar months next after
the date of the said Letters Patent.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Alfred Jeffery, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, as follows
(that is to say) —
My Invention consists in using or applying a solution of corrosive sublimate,
videlicet, corrosive sublimate dissolved in spirit, as a wash to wood and
certain other substances requiring to be exposed to water, for the purpose of

page_text: preventing the adhesion of animalculæ and vegetable matter, and protecting
the same from much of the injury which they sustain from animalculæ.
To prepare the solution which I use for this my Invention, I mix one part
by weight of corrosive sublimate (which is first to be reduced to a state of fine
powder) with three parts by weight of white naptha in a glazed earthenware
vessel; I cover the vessel; I stir the mixture occasionally to facilitate the
dissolving of the sublimate, and so soon as the sublimate is dissolved I add
one like part by weight of coal oil (sometimes called heavy or dead oil), and stir
the whole until the several ingredients are well mixed. I call this mixture
the solution of corrosive sublimate, and I apply it to such wood and other
substances requiring to be exposed to water as are coated or covered with the
glue, which I call "Jeffery's Marine Glue," or "my Marine Glue," herein-after
mentioned, or pitch, or tar, or mixtures of pitch or tar with other materials,
after such glue, or pitch, tar, or mixtures aforesaid have been applied to such
wood or other substances; and I apply the said solution of corrosive sublimate
to them by rubbing or dressing the surfaces which are to be exposed to the
I
action of water with a sponge containing such solution. For this purpose
use a sponge fixed to a piece of wood, in order to avoid bringing the hands in
contact with the solution.
The glue which I mean by "Jeffery's Marine Glue," or "my Marine Glue,"
'is the glue described in my Specification inrolled in Chancery on the Fifteenth
day of October, One thousand eight hundred and forty-two, under the Letters
Patent therein mentioned granted to me, dated the Fifteenth day of April, in
the same year, for a New Method of preparing Masts, Spars, and other Wood
for Ship Building and other Purposes.
.
Other spirits may be used for dissolving corrosive sublimate besides that
which I use for this purpose as above-mentioned. I do not claim the exclu-
sive right to make the said solution of corrosive sublimate, nor do 1 claim the
exclusive use of the said solution, except as herein-after mentioned; but I claim
as my Invention the use or application of solution of corrosive sublimate,
'videlicet, corrosive sublimate dissolved in spirit, as a wash, for treating such
wood and other substances requiring to be exposed to water as have been coated
or covered with my said marine glue, or pitch, or tar, or such mixtures thereof,
as aforesaid.
In witness whereof, I, the said Alfred Jeffery, have hereunto set my
hand and seal, the Seventeenth day of May, in the year of our Lord
One thousand eight hundred and forty-four.
ALFRED (L.S.) JEFFERY.
