page_text: WILLCOX, of the City of Bristol, Mason, send greeting.
WHEREAS His present Majesty King George the Third in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-eighth day of April last past, for Himself, His heirs and
successors, did give and grant unto me, the said Thomas Willcox, His special
licence, full power, sole privilege and authority, that I, the said Thomas
Willcox, my exors, adñiors, and assigns, and every of them, by myself and

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 lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick upon
Tweed, my Invention of a "PNUEMATIC STOVE FOR HEATING ATMOSPHERIC AIR AND
DIFFUSING THE SAME THROUGH HOUSES, HOT-HOUSES, GREEN-HOUSES, AND OTHER BUILD-
INGS, UPON THE PRINCIPLE OF INTRODUCING A COLUMN OF ATMOSPHERIC AIR INTO A
CHAMBER CONTAINING A STOVE OF A NEW AND PECULIAR CONSTRUCTION, THEREBY
CREATING A RESERVOIR OF HOT AIR CAPABLE OF BEING DIFFUSED BY MEANS OF FLUES
THROUGHOUT BUILDINGS OF ANY DIMENSIONS;" in which said Letters Patent there is
contained a proviso obliging me, the said Thomas Willcox, by an instrument
in writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be per-
formed, and to cause the same to be inrolled in His Majesty's High Court
of Chancery within two calendar months next and immediately after the date
of the said recited Letters Patent, as in and by the same, reference being thereto
had, will more fully appear.

Thomas Willcox, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by the Plan or
Drawing in the margin of these Presents and the following description thereof
(that is to say): -

.
his stove is inclosed in a brick or stone chamber, into v
mitted through an opening at the bottom or under sid
t fourteen inches square, but varying in dimensions
tity of warm air required; the cold air then encircles th
pipes, which are heated by a fire, as marked A at the
; the stove been of a serpentine form, the fire first ascen
again ascends into the smoke flue; by which means it retai
a greater surface of heated metal is exposed to the col
ning rarified, ascends into conducting flues to any part
e it may be required.

page_text: The stove is about four feet high, of a circular plan, and the principal part
of it of a conical shape; the bottom part, marked A, is sixteen or eighteen
inches diameter, and regularly diminishes to the top, which is about ten inches
diameter, and, forming a semicircle, descends the same length about eight
inches diameter, with a connection at the bottom for the purpose of cleaning
that part when required; then, turning in the same manner as before, ascends
about seven inches diameter into the smoke fluc.
The outside or damping door, marked M, is nearly air-tight, to prevent the
fuel being consumed unnecessarily, with a small regulator in the bottom to
admit air when wanted.
The ash box E is of cast iron, resting on small stone or brick pillars, under
which the cold or atmospheric air is first admitted; the flanch, or bearing plate
for the bars and stove, marked D, is fixed on the box E in a sunk rebate three
inches deep, and cemented, on the inside part of which rest the fire bars. The
stoking place, C, about nine inches by three, is on a level with the bars, hopper-
like for convenience of stiring the fire.
The charging door is kept nine inches above the bars, for the purpose of
more easily feeding the fire.
The stove being circular, the fire acts on all parts of it at the same time. It
is manufactured of cast or wrought iron.
The place in which the stove and chamber are erected is generally on the
basement story, and may be kept either cold or warm.
In witness whereof, I, the said Thomas Willcox, have hereunto set my'
hand and seal, the Twenty-first day of June, in the year of our Lord
One thousand eight hundred and nineteen.
