page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, ROBERT

WHEREAS by Letters Patent under the Great Seal of Great Britain,
bearing date the Twentieth day of July now last past, reciting that the said
Robert Hoakesly had invented "A METHOD OF MAKING BRITISH POT ASH FOR
THE USE OF ALL KINDS OF MANUFACTURE IN WHICH FOREIGN POT ASH OR ANY ALKALI
IS USEFUL," His most Gracious Majesty did grant unto the said Robert Hoakesly,

and authority, that he, the said Robert Hoakesly, his exors, adñiors, and

Great Britain called England, the Dominion of Wales, and Town of Berwick-
upon-Tweed, in such manner as to him, the said Robert Hoakesly, his exors,
aditiors, or assigns, should seem meet; and that he, the said Robert Hoakesly,
his exors, adЛiors, and assigns, should and lawfully might have and enjoy the
whole profit, benefit, commodity, and advantage from time to time coming,
growing, accruing, and arising by reason of the said Invention, for and during
the term therein mentioned, to hold the same unto the said Robert
Hoakesly, his exors, adiñors, and assigns, for and during the term of

page_text: contained a proviso that if the said Robert Hoakesly shall not particularly
describe and ascertain the nature of his said Invention, and in what manner
the same is to be performed, by an instrument in writing under his hand and
seal, and cause the same to be inrolled in the High Court of Chancery within
one calendar month from the date of the said Letters Patent, then the same
were to be void.
NOW KNOW YE, that tho said Robert Hoakesly, in pursuance of and
in compliance with the said Letters Patent, by these Presents under his hand
and seal doth describe and ascertain the nature of his said Invention, and in
what manner the same is to be performed, as follows (that is to say):-
The pot ash is made of the following materials, videlicet :-English, Scotch.
Welch, or Irish kelp, foreign barilla, or salts obtained from soap lies by evapora-
tion, or in their calcined state commonly called black ashes, or of soap wastes.
It may be made of any of the above materials mixed with a certain proportion of
the salts extracted from soap lies, or by mixing certain proportions of any two
or more together, so as to suit the particular manufacture it may be adapted
for. It is also made of rock salt mixed with a certain proportion of any foreign
or other alkali. The materials are pounded or ground into small pieces, and
such kinds as are designed to make a pot ash of a particular quality are mixed
together; they are then thrown into an oven or furnace of a particular
construction (a Drawing of which is hereupon delineated), and there by means
of an extraordinary degree of heat are melted into so liquid a state, as to run
out with great case at a channel made in a convenient part of the oven or
furnace, and there collected into pots. Either of the kinds when cold assume
the appearance of foreign pot ash, and are used without any further process.
In witness whereof, I havo hereunto set and put my hand and seal, this
Sixth day of August, in the thirty-sixth year of the reign of our
Sovereign Lord George the Third, King of Great Britain, and so forth,
and in the year of our Lord One thousand seven hundred and ninety-six.
Sealed and delivered (the parchment
appearing to be first duly stamped)
by the within named Robert
Hoakesly in the presence of us.
ROBERT HOAKESLY. (L.B.)
