An Improved Method of and Apparatus for Heating or
Cooking by Gas.
I, LEWIS WALKER LEEDS of 38 Old Jewry, in the City of London, Heating and
Ventilating Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to heating and cooking by the aid of gas.
The invention consists of an improved method of and apparatus for arriving at the
desired result, which is accomplished by means of one or more jets of gas burning
beneath an arch or layer of asbestos or other refractory material, preferably perforated
or provided with tortuous openings placed in or near the base of a superposed receptacle,
closed at its sides and top. Said receptacle may be made of iron or other suitable
material and may be capped with fire brick, upon or under, which an oven or other
arrangement for cooking may be placed while within the heat chamber water or
steam pipes can be located.
This method of heating can be adapted for varying requirements, such as for heating
not only the room in which the apparatus is placed, but also adjoining rooms, or by
means of hot air or water pipes, rooms overhead or at a distance.
Whatever the arrangement employed it is desirable that the gas should burn in the
open with a full supply of air. and the gases or impure products of combustion when
entering or attempting to leave the receptacle, be subjected to the heat of the asbestos
or other arch or layer, as by this means all unpleasant fumes will be destroyed, further
advantages being that the arch becoming thoroughly heated, radiates the heat in a
downward direction to the floor. and when the jets surround an internal polished cone,
secondary radiation as well as reflected heat will be secured, while for the purpose of
taking up any moisture generated in the receptacle, a box of sand may be placed
therein, and when desired an exit flue at the base of the receptacle is used to carry off
the products of combustion.

Cooking by Gas.
1, LEWIS WALKER LEEDS of 38 Old Jewry in the City of London, Heating and
Ventilating 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:-
This invention relates to heating and cooking by the aid of gas.
The invention consists of an improved method of, and apparatus for arriving at the
desired result, which is accomplished by means of one or more jets of gas burning
beneath an arch or layer of asbestos or other refractory material preferably perforated
provided with tortuous openings placed in or near the base of a superposed receptacle
or closed at its sides and top. Said receptacle may be made of iron or other suitable
material, and may be capped with fire-brick upon or under which an oven or other
arrangement for cooking may be placed while within the heat chamber water or steam
pipes can be located.
This method of heating can be adapted for varying requirements such as for heating
not only the room in which the apparatus is placed but also adjoining rooms, or by
means of hot air or water pipes, rooms overhead or at a distance.
To clearly explain how the invention may be practically carried into effect, reference
is made to the accompanying drawings which form part of this specification and in
which
Fig. 1 represents partly in sectional elevation, a gas stove constructed according to
this invention.
Fig. 2 is a plan of same on the line, the asbestos arch or layer being omitted.
Fig. 3 represents in sectional elevation a gas stove with many of the parts shown in
Fig. 1 omitted.
Fig. represents in end sectional elevation a stove placed close to a wall.
Fig. 5 represents in end sectional elevation a stove placed in the wall.
Fig. 6 represents a front elevation of the same.
Fig. 7 represents in sectional elevation a stove adapted to heat the air supplied to an
overhead or other room, and
Fig. 8 represents a plan of the same on the line y, y, the asbestos arch being
omitted.
Whatever the arrangement employed, it is desirable that the gas jets A. should burn
in the open with a full supply of air, and the gases or impure products of combustion
when entering or attempting to leave the receptacle B, be subjected to the heat of the
asbestos or other arch or layer C, as by this means all unpleasant fumes will be
destroyed, further advantages being that the arch C, becoming thoroughly heated,
radiates the heat in a downward direction to the floor, and when the jets A surround
an internal polished cone D, secondary radiation as well as reflected heat will be
secured, while for the purpose of taking up any moisture generated in the receptacle,

page_text: a box of sand E, may be placed therein, and when desired an exit flue F, at the
base of the receptacle is used to carry off the products of combustion.
Referring more in detail to the drawings it will be seen that in Figs. 1 and 2 is
shown the stove when employed not only for general heating purposes, but also as
adapted for heating water or air in the coils G, which have the usual induction and
eduction pipes, while oven H is let into or made to form part of the receptacle B, this
being preferably surmounted by a sand box E, and firebrick or other refractory top or
capping I. The sand box and basket for carrying the arch or layer C, are supported
on projecting lugs or brackets a so that the heat may pass entirely around them.
Receptacle B, is supported on feet or columns J, while cone D is truncated and
perforated at its base in order thai a free supply of air may enter to the centre of the
burners.
In Fig. 3 is shown a stove of somewhat similar construction, except that the water
or air coils, the oven, and exit pipe are omitted.
In Fig. 4 is indicated a rectangular stove adapted to be placed against a wall in
which arrangement an inclined plane is substituted for the reflecting cone.
In Figs. 5 and 6 a stove is represented as being built into and through the wall,
this construction being adapted for heating adjoining rooms by means of one and the
same stove.
In Figs. 7 and 8 an arrangement for heating rooms at a distance is represented, this
being accomplished by means of air supply pipes K which pass through receptacle B
and conduct the air thus heated to the desired points.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is:-
1st. In a gas stove the combination with gas jets burning in the open of a superposed
arch or layer of asbestos or other refractory material carried in or near the base of a
receptacle closed above said arch or layer substantially as described.
2nd. The combination with a gas stove of the kind described of a box of sand, adapted
to absorb the moisture generated, and give it off when the stove becomes thoroughly
heated, substantially as set forth.
Brd. The combination with a gas stove of the kind described of an oven, let into or
forming part of the closed receptacle, substantially as set forth.
4th. The combination with a gas stove of the kind described of water or air pipes
substantially as described.
