AN IMPROVED COOKING STOVE
Year: 1884

page_text: We THOMAS BARROW of Rock Ferry in the County of Chester, Coal Merchant
and CHARLES HENRY BERRY, of Chester Street, in the Borough of Birkenhead,
in the County of Chester, Hotel Keeper do hereby declare the nature of our said
Invention for AN IMPROVED COOKING STOVE to be as follows:-
Our Invention has for its object the arrangement of a stove, that the fire therein
shall be so fed as to cause the smoke and gases from the fresh charges of fuel to
pass over an incandescent portion of the fire and so consume such smoke and gases
and at the same time maintain a fire in such a condition that it is most suitable
for cooking purposes and the heat is applied in such a manner, as to thoroughly
utilize it for the various purposes of the stove.
A stove according to our Invention consists of the following parts, a horizontal
rotary fire grate which is arranged to rotate within a casing and under a " hot-
plate" and ovens, the front of the casing being provided with a charging door for
supplying fuel to the grate, and an opening is formed in the casing to serve when
it is required to expose a portion of the fire, for roasting, or like purposes, such
opeuing being provided with a closing door. The ovens are situated at the back of
the stove and above the fire place and are placed in the casing in such a manner
that the heat from the fire place comes under the ovens and over the sides and top.
A series of return tubes are set round the fire place to serve for heating water
either for circulating purposes, or for direct use and for supplying a steaming
apparatus placed over the "hot-plate" of the stove.
A convenient form of the stove case is cylindrical, the charging door, open fire
space and chimney flue being in the front and the ovens at the back, the "hot-
plate" covering the front half of the stove and provided with suitable openings
for pans and the like as usual in kitcheners.
The fire grate is formed of side bars being rings one over the other and bottom
bars and a fire brick back, the whole being connected together and supported by
brackets. A groove is formed on and underneath the bottom of the grate, in which
run balls or rollers, which support the grate from brackets. The grate is also
provided with a rack and pinion and handle, or with holes to receive a lever so
that the grate can be revolved as required.

page_text: By constructing a stove according to our Invention, we are enabled to keep a
constant and uniform heat of the required temperature at those portions of the
stove requiring such temperatures by always having a portion of the fire in an
incandescent state, about, or near such parts of the stove, and a small portion of
the fuel being non-incandescent, its gases and smoke are caused to pass over the
incandescent portion and are consumed; also we are enabled to position the fire to
suit the particular cooking requirements of the moment.

Figure 3 is a part sectional plan taken through the line Z Z Figure 1.
The stove consists of the following parts. A rotary fire grate A which rotates
within the casing B and under the hot plate C and ovens D. The front of the
casing B is provided with a charging door E for supplying fuel to the grate A.
An opening provided with doors F is formed in the casing B to serve when it is
required to expose a portion of the fire for roasting, or like purposes. The ovens D
are situated at the back of the stove and above the fire grate A and are placed in
the casing B in such a manner that the heat from the fire grate A circulates under
the ovens D and round the hollow sides and top a. H is a coil of water tubes
placed round the fire place A and connected to the boiler J through which the
water circulates and is heated. A pipe I is led from the boiler J to the steamers K.
The back of the grate A is lined with fire bricks b and the inside of the casing B
is lined with fire bricks d. The fire grate A is formed of ring bars e supported by
the brackets e¹ which are carried by the base plate h. The bottom of the grate is
formed of the bars i carried by brackets supported between the brackets e¹ and
the interior cylinder f which forms part of the rotating grate. The rotating grate A
is supported by and runs on the balls L, which run between the groove h¹ on the
plate h and the groove m in the base plate M. The grate A is provided with a
central spindle N, the top of which is connected by the bevel gear n to the
horizontal shaft O carried by brackets on the top of the stove and turned by the
handle P. This gear serves as the means of rotating the grate A as required in
working the stove. The centre portion Q of the stove is utilized as an oven and
is heated by the hollow spaces at the sides and by the flue R at the bottom,
access being obtained by the door Q¹. The main flue S extends round the stove
over the grate A and is enclosed at the open portion F by diaphragms T and U.

page_text: The grate and gases of combustion travel in the direction of the arrow t and the
gases and smoke pass round the flue S over the fire to the diaphragm U they rise
up under the boiler J and enter the flue R as indicated by the arrows and after
passing round through the flue R ultimately escape up the chimney V. The
diaphragm r is fitted in the flue R to form the lead. Apertures are provided in
the casing B to admit air to the flue S to assist combustion of any unconsumed
gases and smoke which may exist therein.
By constructing a stove according to our Invention, we are enabled to keep a
constant and uniform heat of the required temperature at those portions of the
stove requiring such temperatures by always having a portion of the fire in an
incandescent state, about, or near such parts of the stove and a small portion of
the fuel being non-incandescent its gases and smoke are caused to pass over the
incandescent portion and are consumed; also we are enabled to position the fire to
suit the particular cooking requirements of the moment by rotating the grate A
by the gear before spoken of.
We would have it understood that our Invention is not limited to the precise
details shown in the Drawings as it will be evident that the arrangement of ovens,
water heater and details of turning gear may be varied to suit circumstances.
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 :-
First In a cooking stove the use of a rotating fire grate, such as A substantially
as set forth for the purposes specified.
Second The combination of a rotating grate such as A, a flue such as S a feeding
door such as E and passages for air such as g, whereby the gases and smoke of the
fuel are caused to pass over the fire and are consumed, substantially as set forth.
Third The combination of the grate A, casing B, flues S and R ovens D and Q;
water pipes H and boiler J substantially as set forth and as shown in the
Drawings hereto annexed.
Fourth The combination of the grate A provided with turning gear and balls L
provided with a railway such as the grooves m and ' substantially as set forth
and shown in the Drawings hereto annexed.
