PROVISIONAL SPECIFICATION.
Improvements relating to Kitchen Cooking Ranges, and to the
Distribution of Heat for Domestic Purposes.
I, JOHN TOPHAM, of High Street, Arlesey, Hitchin, Bedfordshire, Bookseller,
do hereby declare the nature of this invention to be as follows:-
This invention relates primarily to the cooking range for domestic use and
consists in certain improvements therein by means of which the cooking is effected
wholly or principally by the intervention of steam, the latter being used also for
various purposes of heating such as the warming of rooms or greenhouses, the
boiling or heating of water, the working of engines for electric lighting purposes
or for filling tanks or generally for any object of domestic economy requiring
heat.
The kitchen range resembles ordinary ranges in appearance but the ovens and
the grate are surrounded on every side that can practically be so surrounded with
a water jacket which forms a steam producing boiler. The cooking is thus done
not by direct heat but by the intervention of steam, which latter so far as it is
available may be led off from the boiler as from other steam generating boilers for
the purposes before mentioned. The waste steam may be carried up to the top of
the building and there condensed so that hot water may be had or provided as a
service to any floor, or may be used to supply the boiler. Suitable stop-cocks and
valves, gauges and safety valve or valves should be provided.
The flues from the grate may pass under the ovens to assist in heating the
latter also by the direct use of the waste heat in the gaseous products from the
grate.
The oven may be above the grate and serve the purpose of a steam chest or may
be cut down or removed so as to make the front of the range level and the back
thereof may be carried up for the purpose of providing a steam chest. The flue
may be continued over the oven down the side of the stove under the bottom and
up the opposite side and back on top to the outlet near where it commenced.

Improvements relating to Kitchen Cooking Ranges, and to the
Distribution of Heat for Domestic Purposes.
I, JOHN TOPHAM, of High Street, Arlesey, Hitchin, Bedfordshire, Bookseller,
do hereby declare the nature of this invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates primarily to the cooking range for domestic use and
consists in certain improvements therein by means of which the cooking is effected
wholly or principally by the intervention of steam the latter being used also for
DQ77

page_text: various purposes of heating such as the warming of rooms or greenhouses, the
boiling or heating of water, the working of engines for electric lighting purposes or
for filling tanks or generally for any object of domestic economy requiring heat.
The kitchen range resembles ordinary ranges in appearance but the ovens and
the grate are surrounded on every side that can practically be so surrounded with a
water jacket which forms a steam producing boiler. The cooking is thus done not
by direct heat but by the intervention of steam which latter so far as it is
available may be led off from the boiler as from other steam generating boilers
for the purposes before mentioned. The waste steam may be carried up to the top
of the building and there condensed so that hot water may be had or provided as
a service to any floor or may be used to supply the boiler. Suitable stop cocks
and valves, gauges and safety valve or valves should be provided.
The flues from the grate may pass under the ovens to assist in heating the latter
also by the direct use of the waste heat in the gaseous products from the grate.
The back of the oven jacket may be carried up for the purpose of providing a
steam chest. The flue may be continued over the oven down the side of the
stove under the bottom and up the opposite side and back on top to the outlet near
where it commenced.
In order to more clearly explain the method of constructing the improved stove,
reference may be made to the annexed drawings in which Fig. 1 is a front elevation
thereof. Fig. 2 a plan view, Fig. 3 a vertical section on the line 3. 3. of Fig. 2.
Fig. 4 a vertical cross section on the line 4. 4. of Fig. 2. Fig. 5 is a horizontal
section on the line 5. 5. Fig. 3.
A designates the combustion chamber or cavity in which the grate A¹ is placed,
the latter being of any suitable construction to divide the chamber horizontally or
substantially so into two parts, the upper part to receive the fuel, the lower part
to serve as ash pit. A drawer G is fitted in said lower part for more convenient
removal of the ashes. The chamber A is arranged at one end of the interior of a
tank-like chamber E and at the other end of said chamber E is similarly arranged
the chamber B which serves as the oven. Intermediate of said chambers A and B
the pipe or flue Fl passes from the upper to the lower plates of chamber E.
The combustion chamber A extends from the back to the front of chamber E
and is closed at the back and open at the front, where it may have doors or a door
such as A. It is also preferably closed above though it may be continued upward
as regards its walls at A (Fig. 3) to the top plate of chamber E which top plate
is provided with an opening within the circumference of the flange of walls A³
in which opening is fitted a tubular extension A' extending to the top plate A of
the stove. The chamber A is spaced from the wall of chamber E at the side and
also at the bottom and a similar space separates it from the flue F with which
however it is in communication through the connecting sleeve F. The flue F¹
may be spaced from the back and front of the chamber wall E and it is open at
the top at Fand at the bottom at F to the exterior of chamber E. The oven B
extends to the back of chamber E where it is closed, and to the front where it is
open and provided with a door such as B. It is spaced from the end, the top, and
the bottom of chamber E and also from the flue F
It will thus be apparent that the chamber E is adapted to form a water jacket
for the oven B the combustion chamber A and the flue F, and this chamber E is
utilized as such jacket and forms the water heater or steam boiler of this invention.
It is in open relation at the back with the upwardly extending chamber C which
in its upper part therefore forms the steam chest.
The top plate A³ of the stove is spaced from the top of boiler E and it is
provided with any convenient orifices with removable plates, rings, disks or lids as
in other stoves and cooking ranges. The sides A and the bottom A of the
stove jacket are also spaced from the walls and bottom respectively of the
boiler E.
"D is the smoke stack, and D₁ a deflecting plate which may be rocked on its
axis D2 by means of the exterior handle D³ D'is a diaphragm in the flue F

page_text: forming a continuation of the plate D¹ and separating the flue F into two parts in
the vertical plane of the axis Dr. By this means the products of combustion may
be made to pass direct to the flue and smoke stack to the left of diaphragm D' or
to circulate around the oven B and the jacket of chamber A to the other side of
said plate D', according as the plate D is swung to the right or left respectively.
To provide for combustion of the smoke, air may be admitted through the
pipe H extending from the front of the stove into the flue F' at about the
position shown in Fig. 4 where it opens upwardly as shown in Fig. 5. H¹ Fig. 1
shows an adjustable slide or damper for regulating the admission of air from outside
to pipe H.
Connection with the steam chest C may be made by pipe in any suitable way.
Cocks may be provided to the boiler E.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The improved cooking range or stove having the combustion chamber and
oven jacketted in such a way that said jacket forms a steam boiler substantially
as described.
.
2. The construction of range or stove with oven and combustion chamber
jacketted by and within a steam producing boiler and have the steam chest C
arranged in conjunction therewith substantially as described.
3. The improved cooking range or stove with jacketted combustion chamber
and oven and jacketted flue F¹, said parts being arranged substantially as
described for passage of products of combustion about said jacket, the latter being
adapted to receive water.
4. The construction of cooking rauge or stove as herein described and substan-
tially as illustrated in the drawings hereto annexed.
