"IMPROVEMENTS IN COOKING
STOVES AND IN APPLIANCES CONNECTED THEREWITH FOR HEATING WATER FOR
BATHS AND SIMILAR PURPOSES."
ISAAC CHORLTON, of the City of Manchester.
This Invention relates to improvements in that class of cooking stove for which
Letters Patent, No. 1051, were granted to Amelia Louisa Freund on the 16th
March 1878.
Instead of leaving a space beneath the dust chamber as heretofore, I utilise such
space by constructing an oven therein, this oven being enclosed in an outer metallic
casing, the intervening space constituting the heating chambers or flues of the oven,
which are arranged to communicate at each side through suitable openings or side
flues with the bottom of the heat chamber, and at the back with the nozzle or flue
of the stove, a damper being applied to control or entirely shut off the communi-
cation between the oven and the heat chamber, as desired.
In this manner I allow the hot air and products of combustion from the heat
chamber to pass at will through such intervening space on their way to the chimney,
and thus to heat the oven.
This application of an oven as aforesaid not only ensures the top plate being
more equally heated than heretofore, but by avoiding excessive heat in any one
part of the said plate, so materially assists the heating or cooking operation in the
various utensils placed on the said top plate.
This Invention further consists in the application of a circulating hot water pipe
to this description of cooking stove, whereby water may be heated for baths or
other domestic purposes. In carrying out this part of my Invention I arrange a
pipe communicating with the bottom of a water cistern to pass into and through
the heat chamber, and thence to be continued up the flue of the stove in the form
of a coil, and finally to lead into the same cistern at a higher level.
In some cases I arrange the same description of stove and oven combined, to be
heated by gas instead of by coal or other fuel.

"IMPROVEMENTS IN COOKING
This Invention relates to improvements in that class of cooking stove for which
Letters Patent, No. 1051, were granted to Amelia Louisa Freund on the 16th
March 1878.
Instead of leaving a space beneath the dust chamber as heretofore, I utilise such
space by constructing an oven therein, this oven being enclosed in an outer metallic
casing, the intervening space constituting the heating chambers or flues of the oven
which are arranged to communicate at each side through suitable openings or side
flues with the bottom of the heat chamber, and at the back with the nozzle or flue
of the stove, a damper being applied to control or entirely shut off the communi-
cation between the oven and heat chamber, as desired.
In this manner I allow the hot air and products of combustion from the heat
chamber to pass at will through such intervening space on their way to the chimney,
and thus to heat the oven. This application of an oven as aforesaid not only
ensures the top plate being more equally heated than heretofore, but by avoiding
excessive heat in any one part of the said plate, so materially assists the heating
or cooking operation in the various utensils placed on the said top plate.
This Invention further consists in the application of a circulating hot water pipe
to this description of cooking stove, whereby water may be heated for baths or
other domestic purposes. In carrying out this part of my Invention I arrange a
pipe communicating with the bottom of a water cistern to pass into and through
the heat chamber, and thence to he continued up the flue of the stove in the form
of a coil, and finally to lead into the same cistern at a higher level.
In some cases I arrange the same description of stove and oven combined, to be
heated by gas, instead of and as well as by coal or other fuel.
And in order that this my said Invention may be the more readily understood
and carried into practical effect, I have hereunto annexed a Drawing illustrative of
my improvements, and will now proceed to describe the same by means of the
figures and letters of reference marked thereon.
Fig. 1 is a front and Fig. 2 a side exterior view of a cooking stove with my
improvements applied thereto. Fig. 3 is a front sectional view, and Fig. 4 a side
sectional view of the oven portion of the said stove. Fig. 5 is a sectional plan of
Fig. 1 across the line a, b, and Fig. 6 is a plan of Fig. 1 with the top plate
removed, shewing the mode of applying my improved circulating hot water pipe to
this description of cooking stove.
In all the views, A is the brazier or fire place, depending in the usual manner 4
from the heating chamber B. C is the top plate, and D the dust chamber. All the
foregoing parts of the stove are the same as have hitherto been used in the stove
patented by the said Amelia Louisa Freund as aforesaid, and no improvement is
claimed in them.
In accordance with this Invention I utilise the space which has hitherto existed 4
beneath the dust chamber D by constructing an oven E therein, this oven E being
enclosed in an outer metallic casing F, the intervening space G constituting the
heating chambers or flues of the oven, which communicate at each side through
openings and side flues I with the bottom of the heat chamber B, and the bottom
of such intervening space G also communicates through the opening J and 5
pipe K with the nozzle or flue L of the stove, a damper M being applied to control
or entirely shut off the communication between the oven and heating chamber B as

page_text: desired. In order to ensure the hot air and products of combustion spreading
more effectually over the bottom surface of the oven, I apply division plates N
(see Fig. 5) which compel such hot air and products to pass in the direction of the
arrows on their way from the side flues. In this manner I allow the hot air and
products of combustion from the heat chamber B to pass at will through such
intervening space G on their way to the chimney, and thus not only to heat the
oven E, but to materially assist in the consumption of the smoke. This application
of an oven not only ensures the top plate C being more equally heated than hereto-
fore, but by avoiding excessive heat in any one part of the said plate, so materially
assists the beating or cooking operation in the various utensils placed on the said
top plate. In Fig. 6, O is the hot water circulating pipe, which I prefer to fix in
the heating chamber immediately beneath the top plate, and I connect one end of
this pipe to the bottom of a cold water supply cistern, and the other end of the pipe
to the same cistern at a higher level, and thus I produce a circulation of water
through such pipe and so heat the contents of the cistern, or such hot water
circulating pipe may be employed in conjunction with the intervening copper or
other cylinders now employed for supplying dwelling houses with hot water.
In arranging this description of stove and oven to be heated by gas, I apply the
gas burners in the brazier A or immediately beneath the top plate; and if more
heat is required for the oven, I also apply gas burners in the intervening space
beneath the oven, the front plate P being capable of sliding sideways to obtain
access to such space for this or for cleaning out purposes.
Having thus particularly described the nature of this my said Invention, together
with the best methods with which I am acquainted for carrying the same into
practical effect, wish it to be distinctly understood that I do not confine myself
to the precise details, relative proportions, or dimensions herein before described
and illustrated on the accompanying Drawings, as the same may be considerably
varied without departing from the Invention; but what I claim is,-
1st. The improved combination and arrangement of cooking stove and oven,
substantially as hereinbefore described.
2nd. The application of a hot water circulating pipe under the hot plate of a
cooking stove, substantially as and for the purposes hereinbefore described.
3rd. The employment of gas burners as an alternative method of heating a
cooking stove, substantially as hereinbefore described.
In witness whereof, I, the said Isaac Chorlton, have hereunto set my hand
and seal, this 4th day of February, in the year of our Lord 1881.
