page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHANIEL
MERRIMAN, of Crutched Friars, in the City of London, Tin Manufacturer,
send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Eighth day of May,
in the forty-fourth year of His reign, give and grant unto me, the said
Nathaniel Merriman, my exors, adñiors, and assigns, His especial licence,
that I, the said Nathaniel Merriman, my exors, adñiors, and assigns, during
the term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "A STOVE, GRATE, OR RANGE, UPON AN IMPROVED CON-
STRUCTION, THE IMPROVEMENT ON WHICH IS LIKEWISE APPLICABLE TO THOSE ALREADY
IN USE FOR THE PURPOSE OF CLEARING AWAY FOUL AIR FROM CHURCHES, CHAPELS,
AND ALL OTHER PLACES OF PUBLIC RESORT, AS WELL AS HOUSES, BUILDINGS, AND
ROOMS OF EVERY DESCRIPTION;" in which said Letters Patent there is contained
a proviso, obliging me, the said Nathaniel Merriman, by an instrument in
writing under my hand and seal, to cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled in His Majesty's High Court of Chancery within one calendar
month after the date of the said recited Letters Patent.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Nathaniel Merriman, do hereby describe and ascertain the nature of my said
Invention in manner following, that is to say :--

page_text: My air stove has a hollow or cavity, which surrounds those parts thereof
that contain the fire and are heated thereby, marked in the Drawing, Figure 1,
A, A, A, A, and likewise in Figure 2; and the said hollow or cavity is formed
by a hollow back and sides to the stove, made of iron or other materials, and is
not entirely enclosed, but has two apertures, the one for receiving the foul air
into it to be heated, thereby marked B, Figure 1, and the other for carrying
off the air when so heated, marked C, Figure 1; the aperture, marked B,
communicates with a pipe, passage, or channel marked D, D, D, Figure 1,
which passes upwards, comes through the brickwork of the chimney, is then con-
cealed behind the wainscot, and terminates in an aperture, seen in the room
at E, Figure 1, between the common height of the head and the ceiling, being
the same as E, Figure 2; the other aperture, marked C, is connected with a
pipe, passage, or channel marked F, Figure 1, leading up the chimney and
terminating in or near the small part thereof, about the height of the ceiling,
forming upon the whole a passage for air similar to that of an inverted cyphon
or liquor crane with the ends upwards, the one end in the room and the other
up the chimney, that part being-heated through which the air is to pass off, with
a design to draw off the foul air from the upper part of the room in a rapid
manner, causing it to enter at the aperture marked E, and from thence descend
down the pipe, passage, or channel marked D; D, D, into the hollow or cavity
of the stove marked A, A, A, A, to be heated, and then to ascend and be
