page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, WILLIAM
REDMAN, of the City of New Sarum, in the County of Wilts, Tinplate Worker,
sendeth greeting.
WHEREAS His most Sacred Majesty George the Third, by the grace of
God of Great Britain, France, and Ireland King, Defender of the Faith, and
so forth, in and by His Royal Letters Patent, bearing date at Westminster, the
Twenty-eighth day of July, in the thirtieth year of His said Majestie's reign,
therein reciting, that the said William Redman had, by his Petition, humbly
represented unto His said Majesty, that having by long study and experience, and
at a great expence, invented a "NEW IRON BACK ADAPTED TO ALL SORTS OF STOVES
AND GRATES USED IN FIRE PLACES IN ROOMS, WHICH BY RARIFYING THE AIR WOULD
ACCELERATE AND IMPEL THE ASCENSION OF THE SMOAK, CAUSE THE FIRE IN THE STOVE
OR GRATE TO BURN FREE AND CLEAR, PREVENT ANY SMOAK IN THE ROOM, AND GIVE A
MUCH GREATER HEAT THAN STOVES OR GRATES WITHOUT SUCH BACKS WOULD Do ;" and
that he, the said William Redman, hoping to be repaid for such his great labour
and expence, and wishing to make his said Invention known for the benefit of the
public, therefore humbly prayed that His said Majesty would be graciously pleased
to grant him, the said William Redman, His Royal Letters Patent, for the sole
making and vending the said new invented backs for stoves and grates, within
the Kingdom of England, Dominion of Wales, and Town of Berwick-on-Tweed,
for the term of fourteen years, did, of His especial grace, certain knowledge,
and mere motion, give and grant unto the said William Redman, bis exors,
admors, and assigns, His said Majestie's especial licence, full power, sole
priviledge and authority, during the term of years therein expressed, to make,

page_text: use, exercise, and vend his said Invention within that part of bis said Majestie's
Kingdom of Great Britain called England, His Dominion of Wales, and Town
of Berwick-upon-Tweed, in such manner as to him, the said William Redman.
his exors, admors, and assigns, or any of them, should in his or their discretions
seem meet, and that he, the said William Redman, his exors, ulniors, 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 mentioned,
to have, hold, exercise, and enjoy the said licence, powers, privileges, and
advantages therein granted unto the said William Redman, his exors, adñiors,
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, under and subject to the several proviso's and conditions therein
mentioned and contained, and particularly under and subject to a proviso or
condition, that if the said William Redman should, not particularly describe
and ascertain the nature of his said lnvention, 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 his Majestic's High Court of Chancery, within
one calendar month next and immediately after the date of the said Letters
Patent, that then the same Letters Patent, and all liberties and advantages
whatsoever thereby granted, should utterly cease, determine, and become void,
anything therein-before contained to the contrary thereof in anywise notwith-
standing, as in and by the said Letters Patent, relation being thereunto had,
will amongst other things more fully and at large appear.
NOW KNOW YE, that the said William Redman, in compliance with and
in pursuance of the proviso or condition last above mentioned, hath herein and
hereby particularly described and ascertained the nature of his said Invention,
and how and in what manner the same is to be performed, that is to
say:-
The said new-invented back (which is a false back) is fixed in the stove or
grate and leaves a cavity or space of three inches, or more or less, according
to the size of the stove or grate, between the false back and the real back of
the stove or grate; is made either of wrought iron, cast iron, copper, brass,
or other metal, or of earth, clay, burnt. or unburnt stone, lime, or plaster of
Paris, and of tho hight and width to fit the stove or grato in which it is used,
and is made either with barrs wrought or cast together at each end, of the
distance of a quarter of an inch from each other (except where wrought or
cast together at the ends) or any other distances thought necessary, or clso
made in a solid plate having holes therein of any distances from each other,

page_text: and of any size or figure thought proper, and which false back has close or
solid sides from the bottom to the top, and made to fit the stove or grate in
which it is used; and being fixed therein, and being open both at the bottom
and the top, the air underneath the stove or grate being admitted at the bottom
of the said false back into the cavity between that and the real back, the same
air will be there so rarified by the fire as to accelerate and impel the ascention
of the smoak at the top of the said cavity, will make the fire burn free and
clear, prevent any smoak in the room, and cause the fire to give a much greater
heat than otherwise; and by fixing the same false back in chimneys or fire
places, where there is no stove or grate, against the back of the chimney or
fire place, or by fixing the same to a back of iron leaving a cavity between the
false back and the back of the chimney or fire place, or the back of iron so
fixed to the said false back, the air in the cavity, by being so rarified by the fire
as above, will have the same effect by accelerating and impelling the ascension
of the smoak, and causing the fire to burn free and clear, and preventing the
smoak in the room, as when fixed in a stove or grate as aforesaid; all which
the said William Redman doth declare to be a full description of the nature
of his said Invention, and how and in what manner the same is to be per-
formed.
In witness whereof the said William Redman hath hereunto set his hand
and seal, the Twenty-fourth day of August, in the year of our Lord
One thousand seven hundred and ninety.
