AN IMPROVED CONSTRUCTION OF COOKING STOVE
Year: 1854

page_text: LETTERS PATENT to Matthias Walker, of Horsham, in the County of
Sussex, Ironmonger, for the Invention of "AN IMPROVED CONSTRUCTION OF
COOKING STOVE."
Sealed the 2nd January 1855, and dated the 11th July 1854.
PROVISIONAL SPECIFICATION left by the said Matthias Walker at the
Office of the Commissioners of Patents, with bis Petition, on the 11th
July 1854.
I, MATTHIAS WALKER, of Horsham, in the County of Sussex, Ironmonger,
do hereby declare the nature of the said Invention for "AN IMPROVED CON-
STRUCTION OF COOKING STOVE" to be as follows:-
This Invention consists in a novel construction of cooking stove, embracing
also an ironing stove and hot plate, the chief objects of which are to apply the
heat more economically than heretofore, and to facilitate the clearing out of
the flues. When constructing a stove with a boiler and oven, I set the fire-
place between them, and lead off the heat by lateral openings in the fire-place,
the one current to act upon the boiler and the other to circulate round the
oven. The boiler is set at a higher level than the fire-place, and a fluç is
made under or around it for the passage of the flame and heated gases. This
flue runs into the main flue of the stove or direct to the chimney, and it is
provided with a damper for regulating the draft. The flue for heating the
oven passes over the top of the oven, down the side thereof, and under the
bottom of the oven, and it is there met by an ascending flue which leads to
the chimney. In the top of the stove, just over the side flue, an opening is
made, to permit of the horizontal and vertical flues being readily cleared out,

and the underneath flue is reached by another opening below the oven.
fire-place is constructed of fire bricks, and loose bottom iron bars, easily
replaced; and is provided with a compound cover, which may either be entirely
removed, or merely the inner part thereof, to permit of different sizes of vessels
being placed in direct contact with the fire. A damper is also provided for
regulating the draft through the oven flues, and by means of this and the
before-mentioned damper, the direction of the flame and heated gases may be
directed entirely to the boiler or the oven. In some cases I propose to
construct the stove without the boiler or without the oven, according to the
requirements of the purchaser.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Matthias Walker in the Great Seal Patent Office on the
11th January 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I. MATTHIAS
WALKER, of Horsham, in the County of Sussex, 'Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
- Patent, bearing date the Eleventh day of July, in the year of our Lord One
thousand eight hundred and fifty-four, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Matthias Walker, Her special license that I, the said Matthias Walker, my
exccutors, administrators, and assigns, or such others as I, the said Matthias
Walker, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
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 AN IMPROVED
CONSTRUCTION OF COOKING STOVE," upon the condition (amongst others) that I,
the said Matthias Walker, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
"
NOW KNOW YE, that I, the said Matthias Walker, do hereby declare
the nature of my 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, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say): —

page_text: the flues.
This Invention consists in a novel construction of cooking stove, embracing
also an ironing stove and hot plate, the chief objects of which are to apply the
heat more economically than, heretofore, and to facilitate the clearing out of
When constructing a stove with a boiler and oven, I place the fire
between them, and lead off the heat by lateral openings in the fire-place, the
one current of heated gases to act upon the boiler and the other to circulate
round the oven. The boiler is set at a higher level than the fire-place, and
by means of a flue the flame and heat is made to pass under it. This flue
Funs into the main flue of the stove or direct to the chimney, and it is provided
with a damper for regulating the draft, and also with soot doors or openings
for clearing the flues. The flue for heating the oven passes over the top of
the oven, down the side thereof, and under the bottom of the oven, and it is
there met by an ascending flue which leads to the chimney.
In the top of the stove, just over the side flue, an opening is made, to permit
of the horizontal and vertical flues being readily cleared out, and the space
underneath is reached by another opening below the oven. The fire-place is
constructed of fire bricks, and loose bottom iron grate bars, any one of which
may be easily replaced; and it is provided with a compound cover, which may
either be entirely removed, or merely the inner part thereof, to permit of
different sizes of vessels being placed in direct contact with the fire. A
damper is also provided for regulating the draft through the oven flues, and
by means of this and the before-mentioned damper, the direction of the flame
and heated gases may be directed entirely to the boiler or the oven.
In the accompanying Drawing, Fig. 1 represents in front view, and Fig. 2,
in longitudinal vertical section, my improved cooking stove; Fig. 3 is a trans-
verse section, taken in the line 1, 2, of Fig. 2; and Fig. 4 is a similar view,
taken in the line 3, 4, of the same Figure. a, a, a, is the body of the
stove; 7, b, the fire-place, the sides and back of which are lined with fire
lumps, and the grate bars c, c, are all loose, for the convenience of removing
any that may become broken or damaged. A removeable lid or cover dis
adapted to the fire-place, and may be taken away when it is required to place
any vessel immediately above the fire. It will be seen that the flame and
heat from the fire pass along the lateral passages or flues c, e, and consequently
heat the top plate f, f, of the stove, and make it answer the purpose of a hot
plate. A removeable boiler g, g, is adapted to an opening in the top plate f,f,
so that the flame from the fire may act directly on its bottom. In the
Drawing I have shewn an oven h, h, immediately beneath the boiler; and
another and larger oven i, i, is placed on the other side of the fire-place, as
shewn at Fig. 2; and the heated gases from the fire, after passing along the

page_text: flues e, e, over the top of the oven, descend down the side flues j, j, and under
the ovens to the bottom of the back flues k, k, from whence they pass upward
to the main central flue or chimney.
These flues, k, are provided with dampers 1, 1, for the purpose of regu-
lating the draft, and soot doors for the convenience of clearing the flues. An
ash pan m is placed beneath the fire-place, and doors or openings n, n, are
provided in the flues under the ovens, in order to obtain easy access thereto
for the purpose of clearing the same. Openings, provided with covers o, are
made for the like purpose in the top plate f. f. In some cases I propose to
construct the stove either without the boiler or without the oven, according to
the requirements of the purchaser, but the arrangement of the flues for either
remaining portion will remain the same as above set forth.
I
I propose to effect a further economy of the heat, by applying the waste
heat to warm air that is made to traverse pipes placed in the flues.
In Figures 2 and 4, 8, s, are pipes supplied in any convenient manner
with air from the room or the external atmosphere, and as these pipes are
placed in the flues, the air contained therein becomes heated, and may be
conveyed by pipes to any other apartment or part of the house that requires
warning or airing.
Having now described the nature of my Invention of "An Improved Con-
struction of Cooking Stove," and explained the manner of its application,
I wish it to be understood that I claim the arrangement and construction of
parts herein shewn and described, or any mere modification thereof, whereby
the heat is more economically employed than in the ordinary construction of
cooking stoves, and more ready access is given to the several flues and passages
for the purpose of clearing the same.
In witness whereof, I, the said Matthias Walker, have hereunto set
my hand and seal, the Tenth day of January, in the year of our Lord
One thousand eight hundred and fifty-five.
