IMPROVEMENTS IN COOKING STOVES
Year: 1885

page_text: I, JOSEPH TWYEROULD of 39 Ashton Road Oldham in the County of Lancaster
Machinest do hereby declare the nature of my Invention for "IMPROVEMENTS IN
COOKING STOVES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
My improvements are chiefly applicable to the class of stoves used for cooking
by means of oil or similiar liquids, fish, chipped potatoes &c but may be applied to
other descriptions of cooking stoves.
They consist of upright circular stoves provided with an external casing formed
in such a manner that an open airspace is left all round the outside of the fireplace
and cooking pan, The top is covered by a circular case of thin sheetmetal, in the
side of which is cut an opening of suitable size to admit of access to the cooking
pan. This opening can be closed if required by means of a door, also made of sheet
metal sliding in grooves round the outside of the circular case. This circular case
is made with an upper compartment in which is a sheetmetal drawer, which is
provided with a suitable hook or catch, so that it can be hung upon the circular
case in front of the opening, and so filled from the cooking pan, with perfect
convenience, and then replaced in the upper compartment, which is kept hot by the
fire beneath, until its contents are required for consumption.
For the convenience of the user, the whole of this upper case revolves and can be
turned to any side of the stove.
The lower part of the stove or ashpan is provided with a funnelshaped guide of
sheet metal, so that in case the oil or other liquid in the cooking pan should boil
over, it does not fall into the fire, but is conducted into the ashes and so
extinguished without risk.
The ashpan is also provided with an internal casing of sheet metal, in order to
prevent the heat of the fire from affecting the room in which the stove is standing
in summer. This can be removed when the heat of the stove is required to warm
the room.
The stove is also provided with a double flue, the external tube leading from the
outside casing of the stove and conveying away any offensive smell arising from
the cooking, when the damper of the internal tube is closed; when the damper is
open the draught of the stove draws the effluvia through the fire, thus destroying
its noxious qualities.

page_text: In order that the foregoing may be better understood I send herewith a sheet of
drawings in which Fig. 1 is a side elevation and Fig. 2 a section of the stove in
both Figures a indicates the outside casing b the circular case of sheetmetal in
which the opening c can be closed by the sliding door d. e is the upper compart-
ment containing the sheetmetal drawer with the hook or catch g. The dotted
lines show the drawer when hung in front of the stove for filling. The whole
top slides round at h. In Fig. 2 i is the funnelshaped guide to conduct any over-
flow into the ashpan, k is the removable inside casing of the ashpan. is the
outer flue which conducts the effluvia arising from the cooking pan m from the
airspace n when the inside flue o is closed by the damper p. When the damper p
is opened the effluvia is drawn by the draught of the stove through the firebars at r
into the fire and consumed.
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
1at The apparatus, substantially as described and shown hereinbefore and in the
accompanying drawing for the purpose set forth.
2nd A circular revolving top substantially as described and shown hereinbefore
and in the accompanying drawing for the purpose set forth.
3rd A sheet metal drawer, substantially as described and shown hereinbefore and
in the accompanying drawing for the purpose set forth.
4th A funnelshaped guide to ashpan substantially as described and shown
hereinbefore and in the accompanying drawing for the purpose set forth.
5th An internal casing to ashpan substantially as described and shown herein-
before and in the accompanying drawing for the purpose set forth.
6th A double flue, substantially as described and shown hereinbefore and in the
accompanying drawing for the purpose set forth.
