IMPROVE- MENTS IN THE CONSTRUCTION OF STOVES OR FIRE-PLACES
Year: 1862

page_text: LETTERS PATENT to John Tow, of Poland Street, Oxford Street, in
the County of Middlesex, Ironmonger, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF STOVES OR FIRE-PLACES."
Sealed the 15th July 1862, and dated the 18th January 1862.
PROVISIONAL SPECIFICATION left by the said John Tow at the Office
of the Commissioners of Patents, with his Petition, on the 18th January
1862.
I, JOHN Tow, of Poland Street, Oxford Street, in the County of Middlesex,
Ironmonger, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF STOVES OR FIRE-PLACES," to be as follows:-
This Invention has for its object improvements in the construction of
stoves or fire-places for heating apartments or buildings, whereby the draught
can be easily regulated, and the escape of smoke into the room or apartment
prevented. There is also an arrangement by which hot air may be conducted
from such stoves to any part of a building.
Stoves or fire-places constructed according to my Invention are formed in
several parts in order that they may be readily taken to pieces for exami-
nation or repair, and for facility in fixing. The front consists of a plate formed
with an opening to the fire-chamber or grate; this plate fits into a recess
communicating with the flue or chimney. To the lower part of the back

page_text: of the front plate the fire chamber or grate is attached, and above it an arched
or other suitably-shaped -chamber is formed extending from the back of the
front plate, and having an opening into it from the front and below over the
fire. From the upper part of this hood or chamber a flue of suitable size
rises into and communicates with the main flue or chimney. Into this upper
chamber a sliding hood of suitable form is introduced with an opening in the
upper part which corresponds, when the parts are together, with the opening
in the upper part of the chamber leading to the flue; but when it is desired to
reduce or cut off the draught to the chimney, the sliding hood is drawn out
so as to contract or close the passage to the chimney. Between the slide and
the inside of the chamber above described a space is left in which the air
becomes rarefied, and may be conducted by suitable pipes or other channels
to warm or ventilate other parts of the building. The spaces between the
back of the front plate around the sides of the fire-place and air chamber are
filled up to avoid air spaces. Ornamental parts are attached to the front
plate by screws or otherwise, which serve to assist in drawing the stove out of
position when required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Tow in the Great Seal Patent Office on the 18th
July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
Tow, of 10, Poland Street, Oxford Street, in the County of Middlesex, Iron-
monger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Tow, Her special licence that I, the said John Tow,
my executors, administrators, and assigns, or such others as I, the said
John Tow, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF STOVES OR FIRE-PLACES," upon the condition
(amongst others) that I, the said John Tow, my executors or administrators,

page_text: by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Tow, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in the construction of stoves
or fire-places for heating apartments or buildings, whereby the draught can
be easily regulated, and the escape of smoke into the room or apartment
prevented. There is also an arrangement by which hot air may be conducted
from such stoves to any part of a building.
Stoves or fire-places constructed according to my Invention are formed in
several parts in order that they may be readily taken to pieces for exami-
nation or repair, and for facility in fixing. The front consists of a plate
formed with an opening to the fire-chamber or grate; this plate fits into a
recess communicating with the flue or chimney. To the lower part of the
back of the front plate the fire-chamber or grate is attached, but above it an
arched or other suitably-shaped chamber is formed, extending from the back
of the front plate, and having an opening into it from the front and below
over the fire; from the upper part of this hood or chamber a flue of suitable
size rises into and communicates with the main flue or chimney. Into this
upper chamber a sliding hood of suitable form is introduced with an opening
in the upper part which corresponds, when the parts are together, with the
opening in the upper part of the chamber leading to the flue, but when it is
desired to reduce or cut off the draught to the chimney, the sliding hood is
drawn out so as to contract or close the passago to the chimney. Between
the slide and the inside of the chamber above described a space is left in
which the air becomes rarefied, and may be conducted by suitable pipes or
other channels to warm or ventilate other parts of the building. The back of
the front plate, around the sides of the fire-place and air chamber, are filled up
to avoid air spaces. Ornamental parts are attached to the front plate by
screws or otherwise, which serve to assist in drawing the stove out of position
when required.
And in order that my Invention may be most fully understood and readily
carried into practice, I will proceed to describe the Drawing hereunto

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 shows a plan; Figure 2, a front view; Figure 3, a transverse
section; and Figure 4, a vertical section of a stove or fire-place constructed
according to my Invention. a is the front plate, which is fixed in position by
the screws a¹, so as to be readily removed for the purpose of examining or
cleansing the back plate of the stove when required; 6 is an arched plate
forming the upper or outer surface of the air chamber c; and d is another
arched plate or hood forming the lower or inner surface of the air chamber c
through which there is a flue or opening c¹ above the fire into the chimney.
The plate d is capable of sliding to and fro, and when drawn outwards, the
flanch d¹ at the back contracts or partially closes the opening to the flue c',
or, if desired, the parts may be so arranged as to close the flue c¹ altogether.
e, e, are passages leading from the outer atmosphere into the air chamber c,
and f, f, are passages closed by valvular discs f¹, f, by which heated air
can be admitted into the apartment from the chamber c, or the heated air
may be conducted from the chamber c by the pipe h to warm or ventilate any
other part of the building.
The stove is formed and put together in parts, as shewn, or in any other
convenient manner so as to be readily separated or drawn out of position
for the purpose of examination or repair. Ornamental parts may be applied
to the front according to the taste of the maker, and the form and arrangement
of the parts may be varied without departing from the character of my
Invention..
In witness whereof, I, the said John Tow, have hereunto set my hand
and seal, this Seventeenth day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
Witness,
WILLIAM A. LANDER.
