Improvements in or connected with Oil Cooking Stoves.
We, ELIZA THORPE, formerly Eliza Rippingille, Lamp and Stove Manufacturer,
and WILLIAM BRANDON, Foreman, both of The Albion Lamp Company, 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 or connected with oil cooking
stoves whereby an oil stove consisting of a tank, two burners, two chimneys and
a seat for culinary vessels on the top of each chimney is provided with a large
tray or box resting on the top of the aforesaid seats for culinary vessels and con-
sisting of a bottom, enclosed sides and ends and a top, the bottom having two
openings therein corresponding with the upper parts of the chimneys and having
other seats for culinary vessels surrounding said openings whilst the top is pro-
vided with two large circular openings through which boilers or pan can be
passed to rest on the seats fixed on the bottom of said box or tray. The underside
of the bottom of said box or tray has descending webs which serve as guides in
placing it in position on the chimneys and at the same time as guards against
undue draughts. The top of this box or tray is preferably of cast iron with
corrugated rising flanges or with studs all round and partly across the same. This
box or tray serves as a seat for an oven which is of special construction, with a
view to enabling it to be used successfully for baking bread. This oven is formed
with double bottom, ends and top and with extra flue plates a short distance below
the double bottom. The space between these extra flue plates and the double
bottom forms two flues, each of which communicates with one of the spaces at
the ends of the oven and these latter communicate with the space at the top of
the oven, thus forming flues underneath, at the ends and over the top of the oven
from which latter the products of combustion pass through holes across the centre
of the top into a space between the top of the upper flue and an outer plate from
which latter space thev pass away into the open air through openings in the ends
thereof.
The double bottom is employed to prevent the heat from the burners striking
directly upon the bottom of the oven and it is formed preferably of two juxtaposed
plates flanged on sides and ends and meeting along the centre line of the oven and
fixed to the bottom of the oven by the outer flanges but not fixed together along
the meeting line thereby avoiding the effects of expansion and contraction that is
to say any undue warping or twisting of the same. The bottom flue plates herein-
before mentioned extend from each end a certain distance toward the centre so as
to leave an opening for the entry of the heat and products of combustion to the
bottom flues.
A plate preferably of cast iron is placed in the interior of the oven on the bottom
thereof to prevent burning the contents.

secure the same in position on the box or tray and to guard against interfering
draughts.

Improvements in or connected with Oil Cooking Stoves.
We, ELIZA THORPE, formerly Eliza Rippingille, Lamp and Stove Manufacturer,
and WILLIAM BRANDON, Foreman, both of The Albion Lamp Company, Aston
Brook Lámp Works, Birmingham, in the County of Warwick, 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:-
We will describe our invention in connection with the accompanying draw-
ings, in which Fig. 1 is partly a longitudinal section and partly a front elevation
and Fig. 2 a vertical cross section showing our invention applied to an oil stove
and Fig. 3 is a plan of part separately.
The invention has for its object improvements in or connected with that class
of vil cooking stoves consisting of a tank one or more burners, and chimneys and
a seat for culinary vessels on the top of each chimney. In the drawings only the
upper portions of said chimneys a and the seats 6 for culinary vessels are shown, as
this class of oil stove is well known.
According to our invention we provide such a stove with a large tray or box
resting on the top of the aforesaid seats 6 for culinary vessels, and consisting of
a bottom, enclosed side and ends, and a top, the bottom having two openings
therein corresponding with the upper parts of the chimneys a, and having other
seats for culinary vessels surrounding said openings c, whilst the top is pro-
vided with two large circular openings, through which boilers or pans can be
passed to rest on the seats c² fixed on the bottom of said box or tray c. The under-
side of the bottom of said box or tray c has descending webs, which serve as
guides in placing it in position on the seats b for culinary vessels carried by the
chimneys a, and at the same time as guards against undue draughts. The top
of this box or tray c is preferably of cast iron with corrugated rising flanges
or with studs all round and partly across the same. It will be evident that the
number of openings in this box or tray may be varied without departing from the
peculiar character of our invention. This box or tray c may be used for cooking
purposes, or it may serve as a seat for an oven d, which is of special construction
with a view to enabling it to be used successfully for baking bread.
This oven d is formed with a double bottom d. d, ends d. d and top d³, 6 and
with extra flue plates d a short distance below the double bottom d. The
space between these extra flue plates and the double bottom d d forms two
flues d³, each of which communicates with one of the spaces or flues do at the ends
of the oven, and these latter communicate with the space or flue 10 at the top of
the oven, thus forming flues underneath, at the ends, and over the top, of the
oven, from which latter flue do the products of combustion pass through holes "
across the centre of the top plate d into a space between the top plate d of the
upper flue do and an outer plate 3, from which latter space they pass away
into the open air through openings d in the ends thereof. The double
bottom is employed to prevent the heat from the burners striking directly
upon the bottom of the oven d, and the plate d² is formed preferably of two

page_text: juxtaposed plates flanged on sides and ends and meeting along the centre line of
the oven and fixed to the bottom of the oven by the outer flanges, but not fixed
together along the meeting line, thereby avoiding the effects of expansion and
contraction, that is to say, any undue warping or twisting of the same. The
bottom flue plates d' extend from each end a certain distance towards the centre,
so as to leave an opening for the entry of the heat and products of combustion to
the bottom flues d³. A plate e preferably of cast iron is placed in the interior of
the oven on the bottom thereof to prevent burning the contents.
The sides and ends of the oven descend a short distance below the bottom as
shown at 15 to secure the same in position on the box or tray c and to guard
against interfering draughts.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:
1. The improvements in or connected with oil cooking stoves substantially as
herein set forth.
2. The combination with oil cooking stoves of the character herein referred to,
of a tray or box such as c supported on the seats for culinary vessels of said stove,
and an oven such as d supported on the top of said tray or box, substantially as
herein set forth.
3. The combination with an oil cooking stove of substantially the character
herein referred to, of a box or tray having a bottom provided with one, two or more
openings corresponding with the upper parts of the stove chimneys, studs or pro-
jections around such openings forming seats for culinary vessels, enclosed sides
and ends, a top provided with one, two or more large openings, descending webs
on the bottom, and corrugated rising flanges or studs all round and partly across
the centre of the top, substantially as herein set forth, and for the purpose stated.
4. The combination with an oil cooking stove and a tray or box of substantially
the character herein referred to, of an oven having a double bottom, ends and top,
plates below the double bottom forming flues communicating with flue spaces at
the ends and over the top, an extra plate over the double top forming an extra
flue, openings in the upper plate of the double top, and outlet openings in the end
plates leading from such extra flue substantially as herein set forth and for the
purpose stated.
