IMPROVEMENTS IN STOVES OR FIRE-PLACES
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BROWN, of Luton, in the County of Bedford, Ironmonger, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fourth day of September, in the fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick Brown, Her especial licence, full power, sole privilege and authority,
that I, the said Frederick Brown, my exors, adiñors, and assigns, or such
others as I, the said Frederick Brown, my exors, adiñiors, or assigns, should
at any time agree with, and no others, from time to time and at all times
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 "IMPROVEMENTS IN STOVES OR FIRE-PLACES;" in
which said Letters Patent is contained a proviso that I, the said Frederick
Brown, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be enrolled in
Her said Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more
fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Brown, do hereby declare that the nature of my Invention, and
the manner in which the samic is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say)
DESCRIPTION OF THE DRAWING.
Figure 1 represents an elevation of a stove or fire-place constructed accord-
ing to my Invention. Figure 2 shews a section thereof. In each Figure the
same letters are used to indicate similar parts. A is the external cylinder,
containing the fire-place B, but it should be remarked the external casing A
may be made of a different shape, provided the mode of its combination with
the internal chamber B containing the fire be retained. At the lower end of
the interior chamber B, is placed the grating of fire-bars, as is shewn. a is a
piece of talc fixed in the cover b, such cover being applied to the upper part
of the chamber A, there being a sand joint f formed between the upper surface
and the loose cover b. The air for supporting combustion enters at the
opening d, which has a ventilator or regulator to control and regulate the
quantity of air passing to the fire. The air which passes through the ven-
tilator or regulator & passes up the pipe i, and is conducted to the upper
compartment A' of the chamber A, such upper compartment being formed by
means of the partition 7, through which the pipe i passes. In the partition
is formed an opening, through which the chamber B is passed, and by means
of a sand joint h, the air in the upper and lower compartments of the
chamber A are prevented mixing. c is an opening, with a regulator or
ventilator, for the passage of air into the lowest compartment A³ of the
chamber A, such compartment being formed by the partition n, through
which the pipe or tube k passes; hence any air which is admitted at c will be
conducted to the lower compartment A³ of the chamber A, and pass off by the
pipe m to the pipe m', from whence it may be conducted in any direction
or permitted to flow into the room in which the stove is placed. e is a close
door of the ash-pit, and it will be seen that when in use there is no air
intentially admitted into the compartment A², within which the chamber B
is placed: hence whatever atmosphere or vapour may be contained in that
chamber will be from the fire, and the products of combustion will pass from
the chimney A by the pipe o to a chimney. is the entrance into the
chamber or fire pail B. I will now describe the mode of using the stove:-
Observe that there is a suflicient quantity of sand in the two grooves to render

page_text: them air-tight; take care that the fire pail and the ash hole are properly
cleaned out previous to lighting the fire; put some shavings, straw, or paper,
into the ash-hole; also put some shavings or paper in the fire pail with a few
pieces of dry wood; close the ventilator at the back, take off the top b, open
the ash hole door, and ignite the shavings or paper, and as soon as they are
lighted close the door and light the fuel in the fire pail; then put on a few
pieces of coke, and as-soon as they are fairly lighted the pail may be filled up
with fuel, the ventilator c at the back opened to its full extent; the cover
or top 6 put on, and the draught regulated by the ventilator & in front,
according to the degree of heat required. If the bottom of the fire pail should
require cleaning out while the stove is in action, open the ash hole door and
rako it with a hook; as soon as this is done close the door again or the fire
will soon go out. Coke or anthracite coal is preferred to any other fuel. It
will thus be seen that the atmospheric air for supporting combustion is intro-
duced above and descends down amongst the fuel, the products of combustion
passing down between the fire bars into the compartment A², and from thence
as described.
Having thus described the nature of my Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not confine
myself to the precise details shewn, so long as the peculiar character of my
Invention be retained; but what I claim is, the mode of placing a chamber B,
(having fire-bars or suitable grate), within a chamber A, when the air for
supporting combustion of the fuel in the chamber B is caused to pass down-
wards through and amongst the fuel, and the products of combustion pass
between the fire-bars or grating, as described.
In witness whereof, I, the said Frederick Brown, have hereunto set my
hand and seal, this Twenty-second day of March, in the year of our
Lord One thousand eight hundred and forty-two.

page_text: AND BE IT REMEMBERED, that on the Twenty-second day of March,
in the year of our Lord 1842, the aforesaid Frederick Brown came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute made for that purpose.
