IMPROVEMENTS IN COOKING RANGES
Year: 1885

page_text: We ARTHUR HENRY OAKDEN and WILLIAM CHARLES SHARPE 116 and 118 Clee-
thorpe Road Grimsby in the county of Lincoln Wholesale and Retail Ironmongers
do hereby declare the nature of our invention for IMPROVEMENTS IN COOKING
RANGES to be as follows:―
The improvement claimed is the complete control of the draught by a new
arrangement of dampers and flues (as in accompanying Illustrations) whereby the
oven can be heated either at top or bottom.
The oven has flues all round and at back.
The advantage claimed is that anything placed inside the oven can be either
baked or roasted to perfection by simply changing the course of the draught by
means of the dampers, thereby obviating the necessity of removing the contents of
the oven from one shelf to another.
The arrangement of the flues insures a perfect heat either at top or bottom as
required.
It is therefore calculated to meet the requirements of an oven which will cook
and brown the contents as desired.
Figure 3. shows the direction of the draught when the top heat is required for
browning and roasting.
Figure 2 shows the direction of the draught when the bottom heat is required
for baking.
Figure 1. shows the direction of draught when the oven is not required for use.
Figure 4. shows an oven with the hot plate on a level with the fire and boiler
hot plate, the same arrangement applies to figure 4 as to figures 1. 2. 3 but with
1 damper less.
Figures. 1. 2. 3 and 4 accompanying this specification shows the oven only, with
the front plate removed, and also front plate of chimney flue.

We ARTHUR HENRY OAKDEN and WILLIAM CHARLES SHARPE of 116 and
118 Cleethorpe Road, Great Grimsby in the County of Lincoln Ironmongers, do
hereby declare the nature of our invention for IMPROVEMENTS IN COOKING
RANGES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The Improvement claimed is the complete control of the draught by an entirely
new arrangement of dampers and flues (as in Illustrations sent with Provisional
Specification) whereby the oven can be heated either at top or bottom as desired.
The oven has flues all round and at back,
The advantage claimed is that anything placed inside the oven can be either
Baked or Roasted to perfection by simply changing the course of the draught by
means of the dampers.
Another advantage claimed is that this Range is a decided improvement over
ordinary Ranges as the one oven can be used either as a Baker or Roaster which
makes it capable of doing the work of a Range with two distinct ovens.
The arrangement of the flues insures a proper heat either at the top or bottom
as required.
Figure 3 shows the direction of the draught when the top heat is required for
browning and roasting..
Figure 2 shows the direction of the draught when the bottom heat is required
for baking.
Figure 1. shows the direction of the draught when the oven is not required
for use.
Figure 4. shows an oven with the hot plate on the same level as fire and boiler
hot plate the same arrangement applies to figure 4. as to figures. 1. 2. 3 but with
one damper less.
As a substitute for the two dampers on the side of the oven, if desired the
draught can be controlled by one damper in shape representing an angle of
about 95° which is moved by a horizontal rod coming through the front of oven
frame, which by drawing out about 2 opens the bottom flue and by pushing
backward opens the top flue as shown on Figure 5.
Explanation of Figure 5.
A. Shows the opening through which the fire passes to the oven.
B The Rod by which the damper D is worked.
C. C Projecting tab for damper to fit against.
D. The Damper.
E. E. Shows top & bottom level of oven.
F. F. Shows the outlines of oven.
G. G. The sweep of damper D.
H. H. The openings from oven flues to chimney flue.
This does not in any way alter the draught or arrangement of the flues running
round the oven different to the two separate dampers before mentioned but is

page_text: simply a developement of the parts, described in our provisional specification, to
simplify the arrangement where any objection is formed against the use of two
separate levers to open and close the dampers.
To meet the wants of those who get confused by the use of three separate
dampers which necessarily require three distinct handles or levers we have
introduced, this developement which although not altering in any way the principle
of the range, reduces the number of handles or levers from three to one, which
obviates the possibility of the wrong use of the dampers at the same time making
the range the climax of simplicity.
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. The arrangement of the dampers.
2. The arrangement of the flues.
3. The means by which the combination of flues and dampers convey and
control the heat to and around the oven as set forth in this specification and
