Improvements in the Construction of Oil Cooking Stoves.
I, HOWARD WILKINS WRIGHT, of 39.) New John Street West, Birmingham,
in the County of Warwick, Lamp Manufacturer, do hereby declare the nature of
my said invention to be as follows:-
The object of my invention is to provide means for avoiding the wearing out of
oil cooking stoves by the action of the heat upon those parts of the stove nearest to
the flame, and also by the action of the water which, spilt from the kettle or other
boiling utensil, causes any parts formed of sheet iron to corrode, and, in time, to
become destroyed.
According to my invention, I construct the flue of cast iron, cast in one or more
piece or pieces of the required size, and provided with one or more flange or flanges,
by which it can be attached, by screws or otherwise, to the other parts of the stove.
Or the flue may be cast in one piece with the bottom of the oven; the object being
to construct the whole of those parts within which the flame is contained, and which
are most directly affected by the heat, of cast iron instead of sheet iron.
For the same purpose I construct the top of the stove with an inverted domed
cavity, having an opening with flange or otherwise at the bottom, to which the flue
is fitted by screws or otherwise.
Around the bottom opening of the said inverted dome, I may construct a sunken
well for the purpose of receiving any water which might be spilt, and preventing
such from reaching the flame. The rim of such well I specially arrange to act as
a support for small boiling utensils,
:
In the sides of this dome I may provide openings, for the passage of the heated
air and gases generated by the flame, which, after striking the bottom of the
cooking utensil placed over the dome would thereby be caused to pass over the top
of the oven.
It is evident that I may, if I prefer to do so, cast the domed cavity separately
from the top and so arrange it in relation to the top, that the edges of the opening
in the top upon which the boiling utensil rests, shall project over the upper edge
or flange of such domed cavity thus bringing the air holes in the domed cavity
under the cast iron top, thereby effectually preventing the possibility of any water,
boiling over or spilt, reaching the sheet iron under top.
It is further evident that I can, if I desire, cast my said flue with its flanges or
otherwise with part of the said inverted dome attached in two or more pieces so
arranged as to come together as a complete flue etc. by means of screws or other
arrangements.

I, HOWARD WILKINS WRIGHT, of 390 New John Street West, Birmingham
in the County of Warwick, Lamp Manufacturer, do hereby declare the nature
of my said 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 means for avoiding the wearing out of
oil cooking stoves by the action of the heat upon those parts of the stove nearest
to the flame, and also by the action of the water which, spilt from the kettle or
other boiling utensil, causes any parts formed of sheet iron to corrode, and, in time,
to become destroyed.
According to my invention, I construct the flue of cast iron, cast in one or more
piece or pieces, of the required size and provided with suitable means by which it
can be attached to the other parts of the stove. For the same purpose I construct
the top of the stove with an inverted domed cavity, provided with flanges, ribs and
suitable openings whereby water is prevented from reaching the flame the ribs
acting as a support to small boiling utensils.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a sectional elevation of a portion of a stove constructed according to
my invention and illustrating one method of carrying out the invention.
Fig. 2 is a plan view of Fig. 1.
a is the oven of the stove fitted with one or more shelf or shelves b. c is the flue
formed of cast iron, cast in one or more piece or pieces, the parts being fitted
together by means of flanges and projections or lips and screws, or by other suitable
Ineans. The flue is provided with the usual opening d in the side which is fitted
with a mica window as shown. The lower portion of the flue c is formed with a
flange e to which the bottom plate f of the oven is fixed, but in some cases I cast
the bottom plate integral with the flue. 9 is a shell fitting the lower end of the
flue c and secured thereto, one end being cut away to accommodate the cone of the
burner when being passed into position on the lamp.
The upper end of the flue is provided with an inverted dome h formed with
flanges i surrounding the opening of the flue to prevent water gaining access to the
flame, k. k being ribs for supporting utensils which are too small to rest upon the
opening in the top plate m. This dome may be cast integral with the flue or a
portion of the flue or it may form part of the top plate m, in either case being cast
in as many pieces as is found by experience to be best. Although the opening lis
shown larger than the dome h, I find it advantageous in some cases to limit the size
of such opening to the size of the dome or even smaller thus effectually preventing
any water which may boil over or be spilt reaching the sheet iron plate n of the
oven; the dome may be provided, if found necessary, with an outlet pipe or opening
for removing water collected by the dome.
When the dome is cast with the top plate m suitable openings are formed in the
side to allow the heated air and gases to pass out of the dome and travel over the
top of the oven.
It will thus be seen that the whole of these parts within which the flame is
contained and which are most directly affected by the heat and by spilt water are,
according to my invention, constructed of cast iron which is more suitable for
withstanding the corroding action of the heat and water than the sheet iron now
universally used.

page_text: 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. The improved construction of oil cooking stoves, substantially as described.
2. In oil cooking stoves, forming the flue, and other parts liable to corrosion by
heat or water of cast iron, substantially as described and illustrated by the
drawings.
3. In oil cooking stoves, the application and use of an inverted dome provided
with flanges ribs and openings, cast in one or more piece or pieces separate from or
integral with the top plate or flue substantially as and for the purposes herein before
described and illustrated by the drawings..
4. The method of and means for preventing water which has boiled over or
become spilt from gaining access to the flame, substantially as described and
illustrated by the drawings.
