PROVISIONAL SPECIFICATION.
Improvements in and relating to Cooking Ranges.
I JAMES NUTTALL of Castle Works, Dane Street Rochdale in the County of
Lancaster Cooking Stove Manufacturer do hereby declare the nature of this
invention to be as follows:-
My invention relates to cooking ranges but more particularly to circular ranges
or apparatus for cooking chipped or sliced potatoes in oil or oleaginous matters.
My invention has for its object to adapt and apply coal gas as a source of heat
for cooking purposes in such cookers as hitherto coal has and is generally used
for heating.
According to my arrangement I provide or employ jets of gas below the pans
containing the potatoes to be cooked and in combination therewith I employ or
arrange certain means for carrying away the waste gases after the same have been
fully utilised for cooking and heating purposes.
is
According to my present construction I provide immediately below the cooking
pan or pans a series or any convenient number of gas burners of any suitable
shape to which access may be had when required to be ignited-when coal gas
emitted therefrom thro' the connections from a gas main-by means of suitable
openings at the upper part of the range.
In connection with the heating space or cavity I provide a suitable conduit pipe
leading from the said space to or terminating at or immediately below a chamber
or "hot chamber" in which the potatoes may be placed after being cooked, by
this means the waste heat may be utilised thence the said waste gases are allowed
to pass out into a flue or orifice into an exit flue or pipe at the lower part of
which is provided a body or well of water by which means the gases become
condensed such condensed gases are allowed to pass out and away through an
overflow pipe.
Dated this 8th day of June 1894.

Improvements in and relating to Cooking Ranges.
I JAMES NUTTALL of Castle Works Dane Street Rochdale in the County of
Lancaster Cooking Range Manufacturer 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 :-
My invention relates to cooking ranges but more particularly to circular or other
ranges or apparatus for cooking chipped or sliced potatoes, in oil or oleaginous
matter.
My invention has for its object a means whereby I adapt and apply coal gas as
a source of heat for cooking purposes in such cookers also an arrangement for
carrying away the waste and condensed gases from the burners and from the
•

page_text: cooking pan also utilizing the waste. heat from the burners for warming the cooked
viands.
It is well known that with stoves at present in use the condensed gases pass back
into the cooking pan and the gas at the air and gas passages of the burners ignite
such being in contact with the heat in the heating space.
According to my construction I provide immediately below the cooking pan a
series or any convenient number of burners-of any suitable form-to which access
may be had conveniently for ignition purposes and the air supply to which
burners is so arranged that the same shall not be liable to fire or ignite.

In connection with the heating area I provide a conduit pipe or connection which
is capable of being adjusted so as to direct or carry the waste heat to or in
aproximity to the "hot chamber used for storing the cooked potatoes and this
being effected before the said heat is allowed to pass into the exit orifice or may if
desired be carried by such pipe direct into the exit flue in either case being carried
away from the cooking pan. At the lower part of the exit flue provide a
collecting surface or cavity and an outlet for the withdrawal therefrom of the
condensed gases, also in the said lower part I place therein water thus forming a
well or reservoir thro' or into which the gases from the pan and the heating
chamber or area are caused to pass before passing out into the atmosphere by
which means the said gases may be divested of odours or at least minimised.
Fig. 1. is a side elevation of my invention applied to an ordinary cooking
stove.
Fig. 2. is a front elevation shewing a detail of Fig. 1. viz. the conduit pipe
for passing the fumes from the heating chamber to the outlet orifice...
Fig. 3. is a plan of Fig. 1. shewing two outlet orifices J. J which are in
connection with one exit flue which said flue may serve two or a double cooking
stove.
The burners A three of which are shewn in Fig. 3 are carried into the heating
chamber B. underneath the cooking pan C. the air supply to which burners is
provided at D. outside the chamber B. which arrangement admits of a free access
of air thereto obviating firing or igniting as would be the case if the air supply
orifices were within the chamber B. the manipulation of the burners or access
thereto being effected under the lift up or hinged tray E. and ignition is effected
thro' the orifice E' communicating with the chamber B. combustion being supported
within the chamber B thro' the air orifice F.
The waste gases or heat from the burners is allowed to pass through the orifice G
into the adjustable flue H. which may be adjusted so as to direct the waste gases
or heat in proximity to the underside I of the "hot chamber" I' as shewn in dotted
lines Fig. 1. or passed into the exit orifice J. together with the gases from the
pan C, or may impinge on a deflecting piece or plate K then on the water surface K¹
which is or may be provided in the outlet or exit flue L. and thus condensed. The
odours of the gases being thus arrested by the means before described before the
same are allowed to pass out into the atmosphere or such odours are or may be
greatly minimised.
When desired the condensed gases may be withdrawn from L. by means of the
cock or tap M.
I arrange or provide the lower part of the casing as at N. with a hinged front
or part O. by means of which arrangement the front or part O. may move about
the fixed point or hinge O' which allows of the said part being drawn back as
shewn in Fig. 3, which I arrange in order to facilitate the control or manipulation
of the cooking or other necessary operations in and about the pan.
"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 :
**
1. In combination the chamber.B having an air inlet orifice F and the burner
or burners A situated relatively to the chamber whereby air may be supplied to

page_text: the said chamber and combustion supported also to the burner or burners outside
the said chamber as and for the purposes herein fully set forth.
2. In combination the exit flue L. with or without the deflecting plate K.
provided with water or having a collecting surface for collecting the condensed
gases and means for drawing off the same thus forming a special receptacle for the
reception of condensed gases as and for the purposes herein fully set forth.
3. The hinged front or part O. as and for the purposes herein fully set forth.
4. In combination the air inlet orifices D. of the burner or burners A. and the
lift up tray E. as and for the purposes herein fully set forth.
