Improvements in Oil Cooking Stoves.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
PORTER, Foreman, both of The Aston Brook Lamp Works, Birmingham, in the
County of Warwick, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in oil cooking stoves with a view
to obtaining a good bottom heat to an upper oven in addition to side and top heat
and at the same time heating a lower oven.
For this purpose we construct an oil cooking stove with a burner or burners and
a seat for culinary vessels at one side of a pair of ovens mounted vertically one
over the other.
The upper oven has its two sides, bottom and top, formed of double walls, a
short distance apart from each other, so as to form a flue around such parts of the
upper oven; the side flue next the burner or burners has a perforated diaphragm
placed therein to partially obstruct the draft therethrough, so as to cause the heat
and products of combustion to travel partly up such obstructed flue and partly
along the bottom flue to the further side flue and from the upper parts of said side
flues to the flue above the oven, whence they escape through openings in the top,
which latter may also be provided with a seat for culinary vessels.
The side flue next the burner or burners and the bottom flue are open to the
space above the chimney or chimneys, and the opening above the latter may be
closed by a culinary vessel or by means of a cover or damper.
The lower oven will be heated from the bottom flue of the upper oven and by
heat passing through the side next the burner or burners.

Improvements in Oil Cooking Stoves.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
PORTER, Foreman, both of The Aston Brook Lamp Works, Birmingham, in the
County of Warwick, do hereby declare the nature of our invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :--
The invention has for its object improvements in oil cooking stoves with a view
to obtaining a good bottom heat to an upper oven in addition to side and top heat
and at the same time heating a lower oven.
In carrying our invention into effect we construct an oil cooking stove with a
burner or burners and a seat for culinary vessels at one side of a pair of ovens
mounted vertically one over the other.

page_text: Our invention is illustrated in the accompanying drawings, in which :-
Figure 1 is a vertical longitudinal section and Figure 2 is a plan of one form of
our improved oil cooking stove, and
Figure 3 is a vertical longitudinal section and Figure 4 is a partial end view
showing a slight modification.
In all the figures like parts are indicated by similar letters of reference.
In the stoves represented in the drawings only one burner is used, which, with its
tank, is represented at Figures 1 and 3 by broken lines.
a is the body of the stove, is the cone, e is the chimney above the burner, dis
a seat for culinary vessels above the chimney c, which seat however may be
closed by a cover or damper as is well understood. e is the upper and fis the
lower oven.
The upper oven e has its two sides, bottom, and top, formed of double walls a
short distance apart from each other, so as to form a flue e¹ e² e 4 around such
parts of the upper oven e; the side flue e¹ next the burner or burners, has a
diaphragm e placed therein at the upper part thereof, which diagram may be
perforated as shown at Figure 1, or solid as shown at Figure 3.
The outlet from the flue et may be through holes e in the top plate e, as shown
at Figures 1 and 2, in which case the top plate e may be provided with a seat for
a culinary vessel, or such outlet may be through holes e formed in the oven body
at the end of the flue e, as shown at Figures 3 and 4, in which case the top e will
be solid. The side flue e¹ next the burner or burners, and the bottom flue e³, are
open to the space above the chimney cor chimneys, and the opening & above the
latter is closed either by a culinary vessel or by means of a cover or damper. The
lower oven will be heated from the bottom flue 2 of the upper oven e, and by
beat passing through the side next the burner or burners which is open to the space
around the chimney c.
By this construction of oil cooking stove the heat and products of combustion are
caused to travel partly up the obstructed flue e' and partly along the bottom flue e
to the further side flue e³, and, when using a perforated diaphragm e as shown at
Figures 1 and 2, they then pass from the upper parts of said flues el e³ to the flue e¹
above the oven e, whence they escape through the openings in the top plate e,
but when using a solid diaphragm e as represented at Figures 3 and 4, the heat
and products of combustion partly rise into the flue or space e¹ and partly travel
along the bottom flue e* through the flues e³ and e', whence they escape through
the openings e³.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In oil cooking stoves the combination of a pair of ovens mounted vertically
one over the other, a burner and flue at one side thereof, an obstructed flue or
space passing up one side of the upper oven, a flue below, at the further side, and
at the top of said upper oven, said Hlues communicating with the flue space above
the burner or burners, and suitable outlet or outlets from said top flue, substantially
as herein shown and described and for the purpose stated.
2. In oil cooking stoves the novel combination and arrangement of parts,
substantially as herein shown and described and for the purpose stated.
