IMPROVEMENTS IN OR APPLICABLE TO COOKING RANGES OR STOVES
Year: 1885

page_text: We ABRAHAM SHEARING COOPER, of Nos 32 & 33, Market Place, Great Yarmouth,
in the county of Norfolk, Ironmonger, and THOMAS HARBORD, of Priory Plain,
Great Yarmouth aforesaid, Smith, Engineer and Fitter do hereby declare the
nature of the said invention for IMPROVEMENTS IN OR APPLICABLE TO COOKING
RANGES OR STOVES" to be as follows:-
This invention relates to improvements in or applicable to cooking ranges or
stoves, whereby the heat is more efficiently utilized for cooking purposes than
hitherto, the smoke is partly consumed, greater facilities are provided for cleaning
out the flues and an economy of fuel is effected.
Our invention consists in so constructing the oven flue that, by operating a slide
or door, the flue can be divided so as to cause the heated air and products of
combustion to pass over the oven before escaping through the fiue or, when the
range is not required for cooking purposes, the said heated air and products of
combustion can pass direct into the flue without passing over the oven.
In carrying out our invention we construct the vertical flue leading from the top
of the range into the chimney, of iron, and the lower part of the same, where it
communicates with the flue over the oven, is provided with a slide or door adapted
to be operated by a handle placed in a suitable position outside the flue.
By this arrangement when the slide or door is raised the heated air and products
of combustion from the fire will pass directly into the flue without passing over
the oven, but when the slide or door is closed, the heated air and products of
combustion pass over the top of the oven and down the side thereof and escape
into the flue from the back of the oven.
Our improved oven flue is provided with a suitable cleaning out door and with a
damper.

Improvements in or Applicable to Cooking Ranges or Stoves.
We ABRAHAM SHEARING COOPER of Nos 32 and 33, Market Place, Great
Yarmouth, in the county of Norfolk, Ironmonger and THOMAS HARBORD of Priory
Plain, Great Yarmouth aforesaid Smith, Engineer and Fitter 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 :-
This invention relates to improvements in or applicable to cooking ranges or
stoves whereby the heat is more efficiently utilized for cooking purposes than
hitherto, the smoke is partly consumed, greater facilities are provided for cleaning
out the flues and an economy of fuel is effected.
Our invention consists in so constructing the oven flue that, by operating a slide
or door, the flue can be divided or cut off so as to cause the heated air and products
of combustion to pass over the oven before escaping through the flue or, when the
range is not required for cooking purposes, the said heated air and products of
combustion can pass direct into the flue without passing over the oven.
In carrying out our invention we construct the vertical flue leading from the
top of the range into the chimney, of iron, and the lower part of the same, where
it communicates with the flue over the oven, is provided with a slide or door
adapted to be operated by a handle placed in a suitable position outside the flue.
In order to enable our invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1 is
a front elevation, figure 2 a back elevation and figure 3 a vertical cross section of
the vertical flue of a cooking range or stove with our improvements applied thereto.
Similar letters in all the figures represent similar parts.
a, represents the vertical flue made of iron and leading from the top of the
range into the chimney; b, is the slide or door which we provide at the lower part
of the flue a, where it communicates with the flue over the oven; c, c, are guides
in which the door b, slides, and d, is the handle outside the flue for operating the
door b; the spindle e, of the handle d, passes through an angular slot f, in the front
of the flue a, and is fixed to a rod g, pivotted at its lower end to the slide or
door b; the angular slot f, allows of the slide or door b, being fixed in its raised
position as shewn in figure 2, by the spindle e, of the handle being passed into one
of the lateral portions of the slot while the vertical portion of the slot allows of
the upward and downward movement of the spindle when raising or lowering the
slide or door b; h, is the cleaning out door and i, is the damper of the flue.
•
By this arrangement when the slide or door b, is raised the heated air and
products of combustion from the fire will pass directly into the flue a, without
passing over the oven but when the slide or door b, is closed, the heated air and
products of combustion pass over the top of the oven and down the side thereof and
escape into the flue from the back of the oven.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is:
1. In a cooking range or stove the use of a slide or door so constructed and
arranged that by operating the same the heated air and products of combustion
can be caused to pass over the oven before escaping through the flue, or direct into
the flue without passing over the oven substantially as herein before described.
2. The improved flue for cooking ranges or stoves herein before described and
represented in the accompanying drawing.
