PROVISIONAL SPECIFICATION.
Improvements in Gas Cooking and Heating Stoves, applicable also
for Lighting Purposes.
We, ALFRED PULLAR of 78 Beulah Hill, Norwood in the County of Surrey,
Physician, and LEWIS WALKER LEEDS of 70 Berners Street, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in stoves which are applicable both for
cooking and heating purposes.
One form of stove constructed according to this invention consists of a bottom-
less chamber provided with suitable doors and with a heating device such as that
described in the Specification to Letters Patent No. 5841 of 1886 which consists
of luminous flame gas jets burning in the open beneath a refractory arch or
overhanging block which may be faced or not with asbestos. Where the arches
or blocks employed do not cover the top of the chamber a sheet of asbestos or
the like is preferably placed above for the purpose of throwing down the heat.
In this chamber and below the gas jets are placed grooves or like devices for
holding trays or pans in which articles to be cooked by the downward radiation
of beat may be placed. Above this chamber may be arranged a removeable oven
or chamber having suitable inlets for the entrance of the heat in which various
things may be cooked water boiled and the like, suitable arrangements being
provided for the object aimed at. The lower or heating chamber may if desired
be provided with a double casing so as to retain the heat and to form a boiler
or water jacket in which water may be boiled or heated means being provided
for drawing off the water and for the escape of steam.
The heating chamber and oven above are preferably mounted on long legs or
supports which will enable the stove to stand on the floor and yet to be within
convenient reach while it will also give sufficient heighth for the downward
radiation of heat onto the floor at a wide angle, when the stove is being used
for the purpose of heating the room.
The body of the stove may be made of pottery ware, enamelled iron, or other
ornamental material so as to present a handsome appearance.
The legs or supports may be made telescopic so that the stove may be raised
to various heights. At about the highest point it will serve the purpose of a
floor lamp for illuminating purposes. On the legs may be arranged clips or like
devices for the purpose of holding a tray in which articles to be cooked may
be placed such tray being preferably of a double form, the lower or outer having
a lining or bottom of asbestos for the purpose of retaining the heat radiated
thereon which it subsequently gives off to the under side of the inner or cooking
pan when the latter is in place.
Dated this 28th day of April 1893.

Improvements in Gas Cooking and Heating Stoves, applicable also
for Lighting Purposes.
We, ALFRED PULLAR, of 78 Beulah Hill Norwood in the County of Surrey,
Physician, and LEWIS WALKER LEEDS, of 70 Berners Street, in the County of
Middlesex, 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 improvements in stoves which are applicable both for
cooking and heating purposes and to a certain extent for lighting also.
To clearly explain our invention reference is made to the accompanying
drawings in which
Fig. 1 is a sectional elevation of one form of heating and cooking stove con-
structed according to our invention the section being taken on the line A B of
Fig. 2 which is a plan of Fig. 1 with the oven removed the right hand
portion shewing same with the cover also removed.
Fig. 3 is an elevation on a reduced scale of the stove, shewn in Figs. 1 and 2
and
Fig. 4 is a view illustrating our invention in the form of a floor lamp adapted
both for heating and cooking.
In the form of stove illustrated in the drawings, we employ a bottomless
chamber a provided with a door and with a heating device such as that
described in the Specification to Letters Patent No. 5841 of 1886 which in the
form shown consists of luminous flame gas jets c (supplied by a pipe d terminating
in a nozzle e to which may be affixed a flexible supply tube) burning in the
open beneath refractory arches or overhanging blocks which may or may not
be faced with asbestos filaments g such block being suitably held on one two or
more sides of the chamber a. When the arches or blocks employed do not cover
the top of the chamber a sheet of asbestos'h or the like may be secured beneath
the cover a similar piece k being secured beneath the pot or kettle opening
cover if the stove is provided with same. Such sheet of asbestos assists in
throwing down the heat. In the chamber and below the gas jets are provided
projections or like devices for holding a tray or pan m in which substances to
be cooked by the downward radiation of heat may be placed. Above this
chamber may be arranged a removeable oven or chamber n having suitable inlets
formed of perforations in the cover i for the entrance of the heat, in which
various things may be cooked, water boiled and the like, suitable arrangements.
being provided for the object aimed at. The lower or heating chamber a may
if desired be provided with a double casing so as to retain the heat and to form
a boiler or water jacket in which water may be boiled or heated means being
provided for drawing off the water and for the escape of steam.
The heating chamber a and oven n are preferably mounted on long legs por
supports which will enable the stove to stand on the floor and yet to be within
convenient reach while it will also give sufficient heighth for the downward
radiation of heat onto the floor at a wide angle, when the stove is being used
for the purpose of heating the room in which case the pan m is removed.
The body of the stove may be made of pottery ware, enamelled iron, or other
ornamental material or of cast iron as illustrated so as to present a handsome
appearance.
In place of the legs or supports p a telescopic leg 9 as shown in Fig. 4 may
be employed so that the stove may be raised to various heights, this arrange-
ment being particularly advantageous where the stove is arranged as a combined
floor lamp and stove as illustrated in Fig. 4.

page_text: In this form the chamber a is supported on brackets secured to the tele-
scopic leg ga shades supported by a suitable wire frame adding an ornamental
appearance to the lamp.
On the legs p or 9 may be arranged projections t or like devices for the
purpose of holding the tray m in which substances may be cooked which do not
require so much heat as they would receive if the tray were placed on the pro-
jections. Such tray m is preferably of a double form, the lower or outer
part m having a lining or bottom of asbestos v for the purpose of retaining the
heat which it subsequently gives off to the under side of the inner or cooking
pan wo when the latter is in place. If preferred the asbestos may be placed
beneath the pan m in which case the pan w need not be employed except it is
desired to have a hot chamber beneath the article being cooked.
In the case of the lamp illustrated in Fig. 4 the gas may be supplied through
the support q from a suitable connection in the floor.
It will be evident that our invention may be embodied in stoves of other forms
and may be modified in various ways.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A stove consisting of a bottomless chamber carrying two or more refractory
arches and burners adapted to produce a luminous flame beneath said arches
substantially as and for the purposes set forth.
2. A stove consisting of a heat chamber containing refractory arches therein
burners adapted to produce a luminous flame beneath said arches a pan for
cooking carried by the framework and a heat collecting chamber below said pan
all substantially as set forth.
3. The general arrangement and combination of parts forming the improved
stove substantially as described
