page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His present Majesty King George the Second, by His Letters
Patent, tested at Westminster, the Nineteenth day of July, in the eighteenth
year of His said Majestie's reign, of his special grace. certain knowledge, and
meer motion, did give and grant for Him, His heirs and successors, unto me,
WILLIAM RADLEY, of South Shields, in the County of Durham, Salt Maker,
my executors, admors, and assigns, His special lycence, full power, sole
priviledge and authority, that I, my executors, adññiors, and assigns, and every
of us, by myself and themselves, or by my and their deputy or deputys,
servants or agents, or such others as I, my executors, adñiors, or assigns,
should at any time agree with, and no others, from time to time and at all times
hereafter during the term of fourteen years from the date of the said Patent,
should and lawfully might, within that part of Great Britain called England,
the Dominion of Wales, and the Town of Berwick-upon-Tweed, make, use,
exercise, and vend, in such manner as to me, my exécutors, adiñors, and
assigns, or any of us, should seem meet, "A NEW SORT OF INVENTION BY
FURNACES FOR BOILING SEA WATER TO MAKE SALT THEREOF, BY WHICH MEANS SEA
SALT MAY BE MADE AS GOOD, MUCH QUICKER, AND AT LESS EXPENCE THAN BY ANY
OTHER METHOD HITHERTO USED OR DISCOVERED, AND WHICH I, BY AND AT GREAT
PAINS AND EXPENCE, HAVE BROUGHT TO PERFECTION," with such other powers and
liberties as is and are therein expressed; nevertheless subject to a provisoe
therein contained, that if I, the said William Radley, should not particularly

page_text: describe and ascertain the nature of the said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand
and seal, & cause the same to be inrolled in His Majesty's High Court of
Chancery within two kalendar months next and immediately after the date of
the said Letters Patent, that then the same Letters Patent, and all libertys
and advantages whatsoever thereby granted, should utterly cease, determine,
and become void, as in and by the said Letters Patent, whereunto relation
being bad, may and doth more fully and at large appear.
NOW KNOW YE, that I, William Radley, in pursuance of the said proviso,
do hereby declare that the said Invention doth consist of a pan or boiler, which
is both preparative and granulating, made of plates of iron fixed together upon
banks of iron, the bottom whereof is flatt, and may be either square, of about
sixteen feet by sixteen, or oblong, or of any greater or lesser size at pleasure,
the sides or ledges whereof are upright planes standing round the bottom so as to
form a vessell of fifteen inches deep or thereab", which said pan or boiler is
placed horizontally on or over a furnace consisting of two fires divided in the
middle by a wall, upon which are placed staples of stone or iron which supports
the middle of the said pan or boiler. The said furnace, consisting of two fires,
is made of stones or bricks, with air holes for giving air. Its sides and ends,
called hearths, are carryed up slooping, or with a batter, till it reach within ten
inches more or less of the pan or boiler, upon which the said pan or boiler
stands on staples of stone or iron of about ten inches high, more or less. The
fewell or coals are thrown into the said furnace at two or more mouths or
doors at the end or ends thereof, and the smoke is conveyed by flewes into two
chimneys, one at each end of the pan or boiler, and by which the fire is diffused
and spread to every part of the pan or boiler, operating so for the purposes
intended, which is as well for the readier making of salt as for the saving of
coals or fewell.
In witness whereof, I, the said William Radley, have hereunto sett my
hand and seal, this Seventeenth day of August, in the eighteenth
year of the reign of our Sovereign Lord George the Second, by the
grace of God of Great Britain, France, & Ireland King, Defender
of the Faith, & so forth, and in the year of our Lord One thousand
seven hundred and forty-four.
