page_text: TAYLOR'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of the Old Park, in the Parish of Dawley, in the County of Salop,
Forgeman, send greeting.
WHEREAS His present most Excellent Majesty King George the Third, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Sixth day of November, in the thirty-fourth year of His reign,
did give and grant unto me, the said William Taylor, my executors, adminis-
trators, and assigns, His especial licence, full power, sole privilege and authority,
that I, the said William Taylor, my executors, administrators, and assigns, by
myself and themselves, or by my or their deputy or deputies, servants, or agents,
or such others as I, the said William Taylor, 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 expressed, should and law-
fully might make, use, exercise, and vend my new, invented "AIR FURNACE ON
AN IMPROVED CONSTRUCTION, MORE SIMPLE IN ITS PRINCIPLE AND MECHANISH, AND LESS
EXPENSIVE IN WORKING AND CONSUMPTION OF FUEL, AND PRODUCTIVE OF A GREATER
PROPORTIONABLE EFFECT, THAN ANY OTHER HITHERTO DISCOVERED," 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 William
Taylor, my executors, administrators, and assigns, or any of us, should in our
discretion seem meet; in which said Letters Patent is contained a proviso that if
J, the said William Taylor, should 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

page_text: inrolled in Flis Majesty's High Court of Chancery within one calendar month
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,
should utterly cease, determine, and become void, anything therein-before con-
tained to the contrary thereof in anywise notwithstanding, as in and by the said
Letters Patent, relation being thereunto had, may more fully, and at large
appear.
NOW KNOW YE, that I, the said William Taylor, in pursuance of and
compliance with the said proviso, do hereby describe and ascertain the nature
of my said Invention, and declare the same is to be performed in manner
following (that is to say):-
The air furnace now invented is built with brick and cast iron, and also
some wrought iron, and may be built for the purposes of this Invention with
stone or any other material that will stand fire, and cast or wrought iron. It
consists of two fire grates or fire-places at each end of the furnace, which may
open either to the front or back, each of which fire grates communicates by a
flew, which is taken out of the bottom or the side, with a stack or chimney
built with brick or stone, which is situate at the back of the furnace and in the
middle between the two fire grates, or as near to the middle as possible. The
furnace might be built of various dimensions so as to suit the different purposes
to which it may be applied, but it must necessarily consist of the two fire grates
and flew, with the stack or chimney in the middle, as above described, which
forms the principle of this Invention and the advantage which it has over other
furnaces. The mode of working it is upon au iron bottom covered with sand or
any other material that will stand fire, which is kept cool by a draft of air passing
under it. The men work in the same way as at the furnaces that are now usod
for the same purposes. The said furnace may be used for making or refining
pig iron sufficient to hammer or roll into stampt iron or half blooms, or for
beating stampt iron to a sufficient heat to shingle under a hammer or roll into
half blooms, or for heating half blooms to draw under a hammer or roll into
bars, or for heating bar iron to roll or slit into nail rods, or any other purpose
that bar, rolled, or rod iron is used for, or for melting pig iron into a proper
state to make castings of any kind. The said furnace is so contrived through-
out the whole process of making malleable iron, from the pig to the nail rod,
that the following great savings are made in the manufacturing, that is to say:
first, that no blast is wanting, and that iron of the same quality and quantity
as that made by this Invention cannot be made with pit coal without blast;
secondly, that it takes less fuel, pit coal being used in its raw state; and,
thirdly, that iron is by this Invention made with les waste, in greater quanti-

page_text: ies, and of a better quality, from the pig to the nail rod, than by any other
process now in use.
In witness whereof, I, the said William Taylor, have hereunto set my hand
and seal, the Twenty-eighth day of November, in the thirty-fourth 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,
and so forth, and in the year of our Lord One thousand seven hundred
and ninety-three.
Sealed and delivered by the above-
named William Taylor (being first duly
stamped) in the presence of us,
ROBT PEMBERTON, jun".
W COUPLAND.
AND BE IT REMEMBERED, that on the Twenty-eighth day of November,
in the thirty-fourth year of the reign of His Majesty King George the Third,
the said William Taylor came before our said Lord the King in His Chancery,
and acknowledged the instrument aforesaid, and all and everything therein
contained and specified, in form above written. And also the instrument afore-
said was stamped according to the tenor of the several Statutes made in the
sixth year of the reign of the late King and Queen William and Mary of
England, and so forth, and in the seventeenth and twenty-third years of the
reign of His present Majesty King George the Third.
Inrolled the Second day of December, in the year above written.
