AN IM- PROVEMENT IN VESSELS FOR CONTAINING LIQUIDS
Year: 1813

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
DICKINSON, of Great Queen Street, Lincoln's Inn Fields, in the County of
Middlesex, Esquire, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of Ja-
nuary, in the fifty-third year of His reign, give and grant unto me, the said
Robert Dickinson, my exors, admors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said Robert Dickinson, my
exors, admors, and assigns, should and lawfully might, during the term of
years therein mentioned, make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "AN IM-
PROVEMENT IN VESSELS FOR CONTAINING LIQUIDS;" in which said Letters Patent
there is contained a proviso that if I, the said Robert Dickinson, shall not
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 cause the same to be enrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, shall utterly
cease, determine, and become void, as in and by the same (relation being
thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Dickinson, do hereby declare that the nature of my said Invention,
and in what manner the same is to be performed, are particularly described
and ascertained as follows, that is to say:-
In place of wood I make casks or barrels of plates of iron rivetted or
soldered together, but I prefer rivetting, and I line or coat the inside of them
with a japan or varnish, or paint, suited to the nature of the materials intended
to be contained in them, which japans or varnishes, or paints, I compose of
the materials in common use for such articles, as ails, rasins, gums, wax,
charcoal, and different earths or oxides, taking care that the vehicle or base
employed in the varnishing, japanning, or painting the inside of casks or
barrels intended for specific purposes be of a kind on which the liquor or fluid
to be contained in them exerts no chemical action. or solution; and in applying
the japan or varnish, or paint, I take particular care to apply a number of
coatings sufficient to prevent the possibility of the fluid getting through any
flaw or crack to the iron of which the cask or barrel is made. This last-
mentioned circumstance is of great importance to be attended to, for when
iron is to be defended by paint, varnish, or japan, from the action of fluids, if
only one or two coats of the material employed for defence be applied, it
generally happens that small imperfections and blemishes; so minute that: the
eye cannot perceive them, do escape detection, and permit the contained.fluid
in time to penetrate to the 'iron, and then to undermine the coating and cause
it to scale off.
In witness whereof, I; the said Robert Dickinson, have hereunto set
my hand and seal, this Fourteenth day of July, in the year of our
Lord One thousand eight hundred and thirteen.
