Year: 1796

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HATELY, of the City of Worcester, Engineer, send greeting.
WHEREAS I, the said Joseph Hately, did, by my Petition, humbly repre-
sent to His most Excellent Majesty King George the Third, that I had, by
long study and application, and after much trouble, labor, and expence, found
out, invented, and discovered "A METHOD OF EXTRACTING AND MAKING FROM
VEGETABLE BODIES A NEW ASTRINGENT ACID LIQUID, APPLICABLE TO IMPROVEMENTS
IN DIVERS ARTS AND MANUFACTURES," which said Invention I, the said Joseph
Hately, conceived would be of general public utility, that I, the said Joseph
Hately, was the first and truc Inventor thereof, and that the same had
never been used, practised, or made by any other person or persons, to the
best of my knowledge and belief, I did therefore most humbly pray His Majesty
that He would be graciously pleased to grant unto me, my executors, ad-
ministrators, and assigns, His Majesty's Royal Letters Patent, under the
Great Seal of Great Britain, for the sole use; benefit, and advantage of
my said Invention, within that part of His Majesty's Kingdom of Great
Britain called England, His Dominion of Wales, and Town of Berwick-
upon-Tweed, for the term of fourteen years, according to the Statute in that
case made and provided; His said Majesty, being willing to give encourage-
ment to all arts and inventions which might be for the public good, was
graciously pleased to condescend to my request, and therefore, by His Royal
Letters Patent, under the Great Seal of Great Britain, bearing date at Wost-
minster, the Nineteenth day of February, in the thirty-sixth year of His
reign, of His especial grace, certain knowledge, and ineer motion, for Him-
self, His heirs and successors, did give and grant unto me, the said Joseph

page_text: Hately, my executors, administrators, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said Joseph Hately, my execu
tors, administrators, and assigns, and every of us, by ourselves, or by our
deputy or deputies, scrvants or agents, or such others as I, the said Joseph
Hately, my executors, administrators, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term of years therein and herein-after expressed, should and lawfully might
make, use, exercise, and vend my said Invention within that part of His
Majesty's Kingdom of Great Britain called England, His Dominion of Wales,
and Town of Berwick-upon-Tweed, in such manner as to me, the said Joseph
Hately, my executors, administrators, and assigns, or any of us, should in our
discretions seem neet; and that I, the said Joseph Hately, my executors,
administrators, 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 of years therein and herein-after mentioned; to have, hold, exercise,
and enjoy the said licence, powers, priviledges, and advantages therein-before
granted or mentioned to be granted unto me, tho said Joseph Hately, my
executors, administrators, and assigns, for and during and unto the full end
and term of fourteen years from the date of the said Letters Patent, next
and immediately ensuing, and fully to be compleat and ended, according to
the Statute in such case made and provided; in which said Letters Patent is
contained a proviso, that if I, the said Joseph Hately, should not particularly
describe and ascertain the nature of my said Invention, and in what manner
the same was to be performed, by an instrument in writing under my hand and
scal, and cause the same to be inrolled in His Majesty's High Court of Chan-
cery within one calendar month next and immediately after the date of the
said Letters Patent, that then tho said Letters Patent, and all libertios and
advantages whatsoever thereby granted, should utterly cease, determine, and
become void, anything therein-before contained to the contrary thereof in
anywise notwithstanding, as in and by the said Letters Patont, relation being
thereunto had, more fully and at large appears.
NOW KNOW YE, that in obedience to the said Letters Patent, and the
proviso therein contained, I, the said Joseph Hately, do hereby describe and
ascertain the nature of my aforesaid Invention, and the manner in which tho
same is to be performed, in manner following (that is to say) :-
Retorts composed of glass, earth, or other calcareous substances must be
made, erected, and prepared, of a convenient size or shape (such as cupola
stovas, kilns, ovens, or air furnaces, &c.), with apertures for the reception of
the vegetable bodies from which the astringent acid liquid is intended to be

page_text: extracted or made, according to my said Invention. To these retorts receivers,
made either of wood or of glass, carth, or other calcareous substances, must
be connected and placed in cold situations, or vermicular tubes surrounded by
water may be connected with the retorts. These receivers or vermicular
tubes must be united to the retorts by other tubes or ducts, so as to form a
communication from the retorts to the receivers or vermicular tubes. The
apparatus being thus prepared, vegetable bodies, either wood, bark, or other
vegetable substances, are to be placed in the retorts and fire applied thereto, of
sufficient heat to expel or evaporate the volatile matter or humidity from
such vegetable substances, which volatile matter or humidity, being
collected in the receivers (whether through a vermicular tube or otherwise),
produces the astringent acid liquid mentioned in the said recited Letters
Patent. Besides which, smoke, and a gross black burnt oil or bitumen, are
also produced therefrom, leaving in the retorts a firm strong charcoal; and by
admitting air into the retorts, so as to consume the charcoal to ashes, they will,
by dissolution in water, produce a fixt salt, and leave an earthy substance. In
order to produce the liquid in larger quantities, and of greater strength than
can be procured by placing the wood, bark, and other vegetable bodies in their
natural state into the retorts, the same will be effected by first saturating such
wood, bark, and other vegetable bodies in a liquor impregnated with aluminous,
nitrous, and vitriolous carths, either in their natural form, or in a purified state.
In witness whereof, I, the said Joseph Hately, have hereunto set my
hand and seal, this Twelfth day of March, in the thirty-sixth year of the
reign of our Sovereign Lord George the Third, by the grace of God
of Great Britain, France, and Ireland King, Defender of the Faith,
&c., and in the year of our Lord One thousand seven hundred and
