IMPROVEMENTS IN GAS COOKING AND HEATING APPARATUS
Year: 1884

page_text: I THOMAS FLETCHER of Thynne Street Warrington in the County of Lancaster
Gas Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN GAS COOKING AND HEATING APPARATUS to be as follows:-
These Improvements have for their object the construction of a compact
apparatus for beating cooking and other similar purposes by means of gas and
consist in so arranging or constructing the apparatus that with one gas fire or gas
burner only the following operations may be simultaneously carried on, that is to
say the room in which the apparatus is fixed may be warmed by an open
incandescent asbestos gas fire, water may be heated under high or low pressure
and cooking may be performed by baking or otherwise in an oven.
In carrying out my Invention I employ a gas fire consisting of a vertical or
approximately vertical back plate upon or into which tufts of asbestos are secured.
At the foot of the back plate is a suitable gas burner so placed that the inflamed
gas arising therefrom may heat or render incandescent the asbestos fibres. Gas
fires constructed in the manner described are already in use but instead of forming
the back plate of fire clay or of fire clay and metal as usual I form the plate of iron
or other metal exclusively.
The back plate may form one side of a water heater or boilor or a water heater
or boiler may be placed behind and close to or in contact with the back plate.
By this arrangement heat from the gas fire will be conducted or conveyed to the
water in the boiler.
The boiler or water heater is by preference a closed cubical vessel provided with
openings for the inlet and outlet of the water.
Above the gas-fire and boiler I place an oven which may be of the type
ordinarily used with gas cooking apparatus, or of any other suitable construction
capable of being heated by the hot gases froin the gas fire below.
Between the top of the back plate and of the boiler or water heater a space is
left or provided through which the heated gases may pass on their way from the
gas fire. The provision of this space adds to the heating surface of the water
heater or boiler and the gases in passing through it raise or maintain the
temperature of the bottom of the oven.
From the space between the boiler and oven the gases may be conducted to the
interior of the oven or they may be caused to circulate around it and so raise it to
the desired temperature without entering the oven or coming in contact with the
food which may be cooking.

page_text: I, THOMAS FLETCHER of Thynne street Warrington in the County of Lancaster
Gas Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
GAS COOKING AND HEATING APPARATUS, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
These Improvements have for their object the construction of a compact
apparatus for heating, cooking and other similar purposes by means of gas and
consist in so arranging or constructing the apparatus that with one gas fire or gas
burner the following operations may be simultaneously carried on, that is to say.
The room in which the apparatus is fixed may be warmed by an open incandescent
asbestos gas fire, water may be heated under high or low pressure, and cooking
may be performed by baking or otherwise in an oven.
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of Drawings the various
Figures whereon are marked with letters of reference, similar letters being employed
to denote similar parts in the various Figures.
Fig 1 is a front elevation of the apparatus, Fig 2 is a vertical section, Fig 3 is a
horizontal section through A. B. Fig 2 and Fig 4 is a horizontal section through
CD Fig 2.
In carrying out my Invention I employ a gas fire consisting of a vertical or
approximately vertical back plate A upon or into which tufts of asbestos bare
secured. At the foot of the back plate A is a suitable gas burner C so placed that
the inflamed gas arising therefrom may beat or render incandescent the asbestos
fibres. Gas fires constructed in the manner described are already in use, but
instead of forming the back plate A of fire clay or of fire clay and metal as usual, I
form that plate of iron or other metal exclusively. The open fire may be used in
the ordinary manner with a "hastener " or a Dutch oven for roasting and similar
operations.
Behind the back plate of the gas fire I fix, place or mount a boiler or water
heater & in such a manner that the boiler is in contact with the back of the
plate A as shown in Figs 2 and 4. In some cases the back plate A may form one
side of the boiler or water heater but I generally prefer the method of construction
first described. In this position of the boiler, heat from the gas fire will be
conducted or conveyed to the water therein through the plate A and through the
top plate from the flue, passage or space e.
The boiler or water heater is by preference a closed cubital vessel provided with
an opening or inlet f for the admission of water and with an outlet g controlled by
a tap or cock h. The material of which the boiler is constructed and the details of
its arrangement will vary according to the conditions under which the apparatus is
to be used. The boiler may be of cast iron but it is preferably constructed of
sheet copper and carried upon bearings or brackets as shown in Fig 2, in this
case the top of the boiler may be protected by the plate i.
Above the gas fire and boiler I place an oven which may be of the type
ordinarily used with gas-cooking apparatus or of any other suitable construction
capable of being heated by the hot gases from the gas fire below.

page_text: Between the top of the back plate and of the boiler or water heater a space e is
left or provided through which the heated gases may pass on their way from the
gas fire. The provision of this space adds to the heating surface of the boiler and
the gases in passing through it comparatively slowly raise or maintain the
temperature of the bottom of the oven if a closed oven is used.
From the space e between the boiler and oven, the heated gases may be
conducted to the interior of the oven as shown in Fig 2 when they finally escape
therefrom by the flue M, or they may be caused to circulate around the oven so as
to raise its interior to the required temperature without coming in contact with
the food to be cooked.
The oven and boiler may be surrounded or partially surrounded by a casing N
between which and the oven and boiler an air space O is left. There may also be
attached to the apparatus any customary or suitable fittings or accessories such as
the plate warmera p p and if desired boiling burners may be placed on the top plate
of the apparatus.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The combination or arrangement of a boiler or water heater and an oven with
an open incandescent gas fire in such a manner that no other burner but that of the
gas fire is necessary for the oven or boiler, substantially as hereinbefore set forth
and described and as illustrated on the accompanying sheet of Drawings.
