PROVISIONAL SPECIFICATION.
Improvements in Regenerative Gas Heating and Cooking Apparatus.
I ANDREW HIGGINSON of Hurst Street Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide simple and efficient apparatus for the
economical utilization of gas for heating and cooking purposes.
Under my invention heating and cooking apparatus is constructed with a case or
chamber having in the interior thereof one or more series of gas jets placed close
together; when such jets are supplied with air to support combustion through
ways heated by the gas-jets and delivering the air beneath the said jets. A flue or
chimney being provided to carry off the products of combustion.
Second. In heating apparatus or ranges any or all of the walls are made hollow
to serve as ways for heating air to support combustion and for delivery into the
space to be heated.
Third. In cooking apparatus or ranges one or more pockets or openings are
provided to receive pans or utensils directly above the gas jets in connection with
a chamber or oven through which the products of combustion pass. The said
chamber or oven has an opening or openings at or near the bottom and the door is
made hollow and serves as a flue for the products of combustion. A chimney may
be used in addition if required.
Fourth. I combine with the chamber or oven under the second part, apparatus
at the top for heating water or liquids by the products of combustion before finally
passing away.
Fifth. A. door or doors are provided for heating or cooking ranges or apparatus
under my invention so as to partly cut off the supply of gas when open.
Sixth. The walls of the apparatus are made double and are filled with material
having low heat conducting capacity, or walls are coated with non-conducting
material.

Improvements in Regenerative Gas Heating and Cooking Apparatus.
I ANDREW HIGGINSON of Hurst Street Liverpool in the County of Lancaster
Engineer, 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:―
The object of my invention is to provide simple and efficient apparatus for the
economical utilization of gas for heating and cooking purposes.
Under my invention heating and cooking apparatus is constructed with a case or
chamber having in the interior thereof one or more series of gas jets placed
close together; and such jets are supplied with air to support combustion through
ways heated by the gas jets and delivering the air beneath the said jets. A flue or
chimney is provided to carry off the products of combustion.
Second. In heating apparatus or ranges, any or all of the walls are made hollow
or double to serve as ways for heating air to support combustion and for delivery
into the space to be heated.

page_text: Third. In cooking apparatus or ranges, one or more pockets or openings are
provided to receive pans or utensils directly above the gas jets in connection with
a chamber or oven through which the products of combustion pass. The said
chamber or oven has an opening or openings at or near the bottom, and the door is
made hollow or with double walls and serves as a flue for the of products of
combustion. A chimney may be used in addition if required.
Fourth. I combine with the chamber or oven under 'the second part, apparatus at
the top for heating water or liquids by the products of combustion. before finally
passing away.
Fifth. A door or doors are provided for heating or cooking ranges or apparatus
under my invention, to partly cut off the supply of gas, when open.
Sixth. The walls of the apparatus are made double and are filled with material
having low heat conducting capacity or walls are coated with non conducting
material.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical section, and Fig. 2 a plan of a heating stove under my
invention.
!
a are the walls of a case or chamber having in the interior thereof a gas pipe b
made with a series of apertures or jets c, d way and cock for connecting the pipe b
to the gas supply. e are ways heated by the combustion of the gas and formed by
double walls a a and partitions a' through which air enters the chamber beneath
the said jets. The case or chamber a being in this case narrow is carried up
sufficiently high to constitute a chimney or flue for inducing the air to support
combustion to pass through the ways e. f is a cap or hot plate on which a kettle
or pan may be placed if desired.
Fig. 3 is a vertical section, and Fig. 4 a plan of a simple form of apparatus for
cooking. Here there is within the chamber a frame g having openings h directly
above the gas jets for carrying cooking utensils i, whilst that portion of the chamber
between the wall a and the depending or vertical portion g' of the frame acts as a
flue and space in which chops, steaks, or the like may be cooked by means of a
movable carrier j. The portion g' of the frame is perforated to allow of the
passage of the products of combustion and heated air from beneath the utensils
into the flue portion of the chamber.
Fig. 5 is a vertical section, and Fig. 6 a plan of cooking apparatus under my
invention in which two series of jets cc' are used so that the food may be cooked
equally on both sides at once. a a' are the double walls of the chamber or case
divided by partitions k horizontally so as to make water boilers above the jets,
or one or both of the spaces may be filled with non-conducting material. gare
vertical perforated partitions the spaces between which and the walls a' form flues
and through which the products of combustion and heated air pass into the centre
of the chamber or case.
Fig. 7 is a vertical section, and Fig. 8 a plan of a modification of cooking range
in which a a' mm' are the double walls, the space between m m¹ being filled with
non conducting material. 66 are gas pipes with jets cc, d gas supply ways and
cocks, a partitions to direct the air between the double walls beneath the gas jets.
openings for cooking utensils above the gas jets. n is the portion of the case
or chamber forming an oven. o are the oven shelves and frame. There is a
space p between the oven frame and the walls m m' up which the products of
combustion and heated air pass. The oven door is made hollow or with double
walls gq as shown in the transverse section Fig. 9 so as to form an exit flue
for the products of combustion and heated air, is a boiler forming the top
of the oven.
The oven door q is fitted with an arm r connected by a rod s with
a regulating valve t in the main gas supply pipe so that when the door is opened
and there is not sufficient air induced through the ways e to support combustion
the supply of gas is reduced. f cover or hot plate, u air openings leading to

page_text: the ways e.
When there are two sets of utensils slides as shown by the dotted
lines v may be used to separate such utensils as are not wanted from the chamber.
The arrows shew the direction of motion of the air currents and products of
combustion. In all the views the same letters denote equivalent parts.
It will be obvious that many modifications of heating and cooking apparatus
may be made without departing from my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:-
First. In heating and cooking apparatus the combination of a case or chamber
with gas jets supplied with air to support combustion through ways heated by the
said jets and delivering air beneath such jets.
Second. In heating and cooking apparatus making walls hollow or double so as
to serve as ways for air to support combustion substantially as set forth.
Third. Cooking apparatus consisting of a case or chamber, utensil holders, oven,
gas jets and air ways, substantially as set forth.
Fourth. In combining with cooking apparatus under my invention a boiler
substantially as set forth.
Fifth. Combining with the doors of cooking apparatus under my invention a
gas supply regulator substantially as set forth.
Sixth. Cooking apparatus under my invention packed with material having low
conductivity to heat substantially as set forth.
Seventh. Heating and cooking apparatus
illustrated.
