IMPROVEMENTS IN KITCHEN RANGES AND COOKING APPARATUS
Year: 1884

page_text: I HOWARD MATRAVERS ASHLEY of Ferrybridge in the County of York Manager
of Ironworks do hereby declare the nature of my Invention for "IMPROVEMENTS
IN KITCHEN RANGES AND COOKING APPARATUS" to be as follows:-
My Invention relates to improvements in Kitchen ranges and other similar
cooking Apparatus, and more particularly, to the Ovens and the flues connected
therewith, being particularly applicable to such Kitchen ranges as described in
the Patent granted to me in January 1882, N° 324. The object of my present
invention is to construct an effective double chambered Oven, having but one door,
and each compartment or chamber by my improved arrangement of the flue, to be
capable of baking from the underside, and browning from the upper side, and I
accomplish this by carrying out my invention in the following manner.
I prefer to make both compartments of my dual Oven, with the corrugated or
waved bottom and sides, as described in my former Patent, one being placed over
the other, so that one door will conveniently close them both. Sufficient space is
left between the top of the lower, and the bottom of the upper chamber to form a
flue. This space is closed by the front and back plates, and one of the side plates,
the other side being open to the main flue. The main flue from the fire passes
under the bottom of the lower compartment, and through a divided vertical flue,
up the side. This vertical flue is divided unequally, the smaller opening leading
to the side of the upper compartment, the larger one being turned into the space
between the two compartments by means of a top plate which extends to the small
flue. To prevent the flame and heated gases from escaping at once through the
small opening or flue, and to diffuse the said heat over all the area of this horizontal
Hue, I arrange a midfeather or partition extending from the division of the vertical
flue near the back plate, diagonally and partially across towards the front plate.
The flame or heated gases are thus caused to pass over the whole of the surface of
the horizontal flue, passing forward in conjunction with the heated gases from the
smaller flue, up the side, and over the top of the upper compartment and finally
escaping into the chimney. In order to regulate the current of heat and cause it
to flow in the desired direction, I fix a sliding plate in such a position that the
opening of the small flue may be contracted, or opened to the full extent as
required.

I HOWARD MATRAVERS ASHLEY of Ferrybridge in the County of York Manager
of Iron Works do hereby declare the nature of my invention for IMPROVEMENTS
IN KITCHEN RANGES AND COOKING APPARATUS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement that is to say :—
My invention in Kitchen ranges and other cooking apparatus relates more
particularly to the ovens and flues, being specially applicable to the Kitchen
Ranges described in my Patent N° 324-1882.
The object of my invention is the construction of an effective double chambered
oven, having but one door, and each compartment capable of taking on the underside,
and browning on the upper side.
The compartments of my dual oven are placed one over the other, so that one
large door will conveniently close them both.
Space is left between the compartments to form a flue; this space is closed by
the front and back plates, and one of the side plates, the other side being open to
the main fluc.
I annex a sheet of explanatory drawings in which the same letters of reference
indicate the same parts in all the figures.
Fig. 1. is an elevation of a Kitchen Range, with the oven front plate removed to
show the flues.
Fig. 2. is a plan of middle flue cut through X. Y.
Fig. 3. is a plan of the top of the upper compartment or oven.
A is the main flue from the fire passing under the lower oven C, and continuing in
a divided vertical flue B, this part is divided unequally, the small opening D leading
directly to the side and top of the upper oven E, the larger opening leading into
the space F between the two ovens, and being covered over with a top plate G.
To prevent the flame and heated gases from escaping at once, directly through
the small opening or flue, and to cause the heat to pass over the whole area of the
top of the oven C before escaping, I arrange a midfeather, or baffle plate H
extending from the top of the division of the vertical flue, diagonally and partly
across the top of the oven C towards the front plate. The flames or heated gases
are thus caused to pass round the end of the baffle plate H, before escaping through
the smaller flue D, with the heated gases and flame coming direct from the fire,
and passing up the side J, of the upper oven, and over the top K to the exit L and
thence to the chimney.
In order to regulate the current of heat, and cause it to travel in the desired
direction, I fix a slide plate M preferably over the flue cover G, so that the opening
of the small fiue D, may be closed or contracted, or be opened to the full extent.
On the top of the upper compartment or oven a somewhat similar baffle plate N
prevents the heated air escaping in a direct line to the escape L. The flue may be
carried at the back of the top oven if desired as well as at the side.
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:-
In Kitchen Ranges and other Cooking Apparatus, the arrangement of the ovens
and flues, as herein described and illustrated.
