page_text: TO. ALL TO WHOM THESE PRESENTS SHALL COME, JOSEPH
JACKSON, of Liverpool, in the County of. Lancaster, Pawnbroker,. sendeth
greeting.
WHEREAS His most Excellent Majesty King George the Third did,
by His Letters Patent under the Great Seal of. Great Britain, bearing
date at Westminster, the Nineteenth day of May, in the fourteenth year
of His reign, give and grant. unto the said Joseph Jackson, His especial
licence, full power, sole priviledge and authority, that the said Joseph Jackson,
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within that part of the Kingdom of Great Britain
called England, the Dominion of Wales, and Town of Berwick-upon-Tweed,
his Invention of "THE WORKING OF A WATER MILL BY THE FORCE OF WATER,
FROM ANY RIVER OB PLACE WHERE THE TIDE EBBS AND FLOWS, AT ALL TIMES,
WHETHER AT HIGH OR LOW WATER, OR WHETHER THE TIDE EBBS OR FLOWS BY A
PARTICULAR CONTRIVANCE AND INVENTION OF CONVEYING THE WATER TO AND FROM
THE WHEEL, BY WHICH MEANS THE WHEEL IS. IN CONSTANT MOTION AND NEVER
STOPS BUT AT THE MANAGER'S PLEASURE; in which said Letters Patent there is
contained a proviso, obliging the said Joseph Jackson, under his hand and
seal, to describe and ascertain the nature of his said Invention, and in what
manner the same is to be performed, and to cause the same to be inrolled
in His Majesty's High Court of Chancery within four calendar months after

page_text: the date of the said recited Letters Patent, as in and by the same, relation
being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, the said
Joseph Jackson doth hereby declare that his said Invention of the Working of
a Water Mill by the Force of Water, from any River or Place where the Tide
Ebbs and Flows, at all Times, whether at High or Low Water, or whether the
Tide Ebbs or Flows by a particular Contrivance and Invention of Conveying
the Water to and from the Wheel, by which Means the Wheel is in constant
Motion, and never Stops but at the Manager's Pleasure, is described in the
manner following (that is to say):-
To convey the water to and from the wheel is to have two revisers, both of
an equal size, the one to receive the water at high water by a sluce or slide,
the other to receive the water from the wheel and to discharge it at low water
by a sluce or slide, to divide the flowing and ebbing of the tide into three
parts; (that is to say) where the tide flows fifteen feet high, five feet for
the upper reviser and five feet for the fall in the wheel and five feet
for the lower reviser, and so by taking in a proper quantity of high water
to carry the wheel, and by discharging it at low water from the lodge below
the wheel, the wheel is in constant motion, and never stands but at the
manager's pleasure. There are two ways of placing revisers, either to have
them right over one another, or to place them side by side, hut one over
another is most compleat, and will take no more ground than if there was but
one reviser, and may be very easily done where the tide flows fifteen to twenty
or twenty-five feet high, by placing a strong floor at a proper height to convey
the water to the wheel, but where the tide runs but a little they must be
placed side by side.
In witness whereof, the said Joseph Jackson, hath hereunto sett
his hand and seal, the Seventh day of June, in the fourteenth 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 seventy-four.
