PROVISIONAL SPECIFICATION.
A New or Improved Combination of Cooking Range Boiler and
Gas Stove.
We, WILLIAM HARLOW, Builder, and HERBERT WARWICK, Bank Manager, both
of 94, Baggrave Street, North Evington, Leicester, do hereby declare the nature
of this invention to be as follows:-
This invention relates to a new or improved combination of cooking range
boiler and gas stove, the object of the invention being to utilize in an effective
manner the heat arising from the gas stove, when the latter is in use, and which
is usually conveyed away to a flue or chimney without any use being made of it.
By our invention, we make provision for utilizing this heretofore wasted heat,
so that during the warm weather or at any time when it is convenient to go without
a fire in the range, the waste heat from the gas stove may be turned through a
chamber or pipe to any convenient point below or around the boiler of the
range usually set at the back of the fire and from which the hot water for the
bath or warm supply for the sink or other purpose is obtained.
To carry out our invention we preferably remove the ordinary side boiler of
the range and place a gas stove in the space usually occupied by the said boiler;
or construct a range having the usual oven and fire grate and leave a space into
which an ordinary gas stove may be placed; or the gas stove might be an
addition to a complete ordinary range.
In any case, however, it is essential that the top and side of the gas stove
should be encased, thereby forming a chamber for the waste heat, and back
boiler may also be suitably encased.
Preferably near the top of the chamber a conducting pipe or other suitable
outlet for the heat may be fixed, the said conducting pipe being turned down
to the underside of the back boiler before mentioned.

The top casing of the gas stove also may be hinged at a suitable point to
allow of free access to the top of the stove for any purpose.

We; WILLIAM HARLOW, Builder, and HERBERT WARWICK, Bank Manager, both
f 94, Baggrave Street, North Evington, Leicester, do hereby declare the nature
[Price 8d.1

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement;
This invention relates to a new or improved combination of cooking range
boiler and gas stove, the object of the invention mainly being to utilize in an
effective manner the heat arising from the gas stove, when the latter is in use,
and which has heretofore been conveyed to a flue or chimney without any use being
made of it.
By our invention we make provision for using this heretofore wasted heat,
so that during warm weather or at any time when it is convenient to be without
a fire in the range, the waste heat from the gas stove may be turned through a
chamber or pipe to any convenient point below or around the boiler of the range
usually set at the back of the fire grate and from which the hot water for the bath,
sink or other purpose is obtained.
To carry out our invention we preferably remove the ordinary side boiler of
the range and place a gas stove in the space usually occupied by the said boiler;
or construct a range having the usual oven and fire grate and leave a space into
which an ordinary gas stove may be placed; or the gas stove might be an
addition to a complete ordinary range.
In either case however, it is essential that the top and side of the gas stove
should be encased, thereby forming a chamber for the waste heat, and the back
boiler may also be suitably encased.
Preferably near the top of the chamber a conducting pipe or other suitable
outlet for the heat may be fixed, the said conducting pipe being turned down
to the underside of the back boiler before mentioned.
Provision may also be made for a side cheek or plate to be used at any desired
time. The top casing of the gas stove also may be hinged at any suitable point to
allow of free access to the top of the stove for any purpose.
Referring to the drawing accompanying this specification,
Figure 1 is an elevation showing an oven, back boiler and gas stove constructed
in one form of our invention.
Figure 2 is a vertical section taken through the fire grate and showing the
usual back boiler of a range and Figure 3 is a vertical section taken through
the gas stove.
A is the oven which may be of any convenient size and shape and provided with
the usual flues. B is the usual back boiler which may also be any convenient
shape and capacity and fixed in suitable position to the usual grate. C is a
gas stove which also may be of any desired shape and size and divided into
chambers C1 and C2. F is a gas pipe represented as a ring, but which might be
of any other shape or consist of straight lengths of pipe provided with jets.
The said pipe F is placed in the recessed top C of the gas stove C and is provided
with a top or cover F¹ which may be hinged at F2 to enable it to be turned back
for any desired purpose.
The said cover may however, be made detachable from the stove so that it can be
removed altogether when desired. It will be seen that the top C of the stove is
by means of the said cover turned into a chamber and the heat instead of being
wasted will pass through the outlet C³ down the pipe C4* and end in close
proximity to the back boiler B. The latter may be provided with an angular
iron cover B¹ to enclose the top and front and thus form a chamber for the heat.
E is a second boiler in sectional plan of shape, having a flue commencing
underneath at D with an opening at the top of the chamber C2 of the gas stove,
passing at I up at the back of the boiler and turning over the top and into the
chamber C and thence down through the pipe C as before described.
It will be readily understood therefore that at any time without a fire, by
lighting the jets in the usual pipe J (shown only in dotted lines in Figure 1) of
the bottom chamber C2 the water in the boiler É may be heated, or when jets H¹

page_text: in the chamber C₁ are lighted the heat may pass through the openings formed in
the back of the said chamber to the boiler E.
Water circulating pipes K pass from any convenient tank to the said boilers
and the gas pipes F, Hand J are supplied through the pipe L.
It will be readily seen therefore that the heretofore wasted heat from the gas
stove may be used as an auxiliary to the fire or the gas used alone for heating
the water in the boiler E.
Where necessary the back part of the recess into which the range, boilers and
gas stove are placed may be built in with brick work or covered with iron plates
as found most convenient for the purpose.
We do not confine ourselves to the precise arrangement herein described as
modifications may be readily made to suit the varying construction of parts of
ranges and gas stoves.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is;-
1. The combination with a cooking range boiler of auxiliary means for heating
the same by conducting the heat from a gas stove to the said boiler substantially
as described and illustrated in the drawing.
3. The combination with a gas stove of a boiler arranged substantially as
described and illustrated in the drawing.
