IMPROVEMENTS IN, COOKING.STOVES OR KITCHEN RANGES
Year: 1875

page_text: LETTERS PATENT to Frederick Thomas Davey, of No. 21, Wellington
Street, Blackfriars Road, in the County of Surrey, and Alexander
Paul Hutchison, of Upper Thames Street, in the City of London,
for the Invention of "IMPROVEMENTS IN, COOKING. STOVES OR KITCHEN
RANGES."
Sealed the 4th Janury 1876, and dated the 5th July 1875.
PROVISIONAL SPECIFICATION left by the said Frederick Thomas
Davey and Alexander Paul Hutchison at the Office of the Com-
missioners of Patents, with their Petition, on the 5th July 1875.
We, FREDERICK THOMAS DAVEY, of No. 21, Wellington Street, Black-
friars Road, in the County of Surrey, and ALEXANDER PAUL HUTCHISON,
of Upper Thames Street, in the City of London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN COOKING STOVES OR
KITCHEN RANGES," to be as follows:-
t
This Invention relates to certain improvements in convertible open
or close fire-cooking stoves or kitchen ranges, whereby they are rendered
more convenient and effective. For this purpose the hood which is used

page_text: for conducting the smoke and products of combustion from the open fire
is hinged or jointed to the back plate of the stove or range, and when
drawn forward sufficient space is left between the bottom edge of the
hood plate and the upper surface or hob of the stove to allow the plate
which covers the fire to be slid back, and thus close and cut off the draft
from the bottom flues.
The hood is formed in two parts, the outer part when pulled out
acting by means of studs to pull out the inner bottom plate which
is suspended on studs, so as to form a clear passage to the chimney.
The hood when closed to form a close cooking stove falls close up
against and level with the back plate of the range, thus affording
increased hob space to the stove.
Another part of our improvements consists in so forming the boiler and
arranging the flues that the split draft passes down flues formed between
the fire-place and the boiler or boilers, thence between the top ends of
the oven and the bottom of the boiler, which is curved off for this
purpose, returning below the oven, where the split draft meets and
passes up the back of the oven and stove to the chimney. The heat is
by this arrangement applied in the most advantageous manner for
heating the hot plate boiler, and oven space being also economised.
The improved hood may be applied to ranges and kitcheners of various
constructions.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Thomas Davey and Alexander Paul
.Hutchison in the Great Seal Patent Office on the 5th January
1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
DAVEY, of Wellington Street, Blackfriars Road, in the County of Surrey,
and ALEXANDER PAUL HUTCHISON, of Upper Thames Street, in the City
of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of July, in the year of our
Lord One, thousand cight hundred and seventy-five, in the thirty-

page_text: ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Frederick Davey and Alexander
Paul Hutchison, Her special license, that we, the said Frederick
Davey and Alexander Paul Hutchison, our executors, administrators,
and assigns, or such others as we, the said Frederick Davey and
Alexander Paul Hutchison, our executors, administrators, and assigns,
should at any time agree with and no others, from time to time and at
all times thereafter during the term therein expressed, should and law-
fully might make, use, exercise, and vend within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN COOKING STOVES OR KITCHEN RANGES;"
upon the condition (amongst others) that we, the said Frederick
Davey and Alexander Paul Hutchison, our executors or administrators,
by an instrument in writing under our or their hands and seals, or
under the hand and seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alexander Paul Hutchison on
behalf of myself and the said Frederick Davey, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
This Invention relates to certain improvements in convertible open or
close fire cooking stoves or kitchen ranges, whereby they are rendered
more convenient and effective.
And in order that our Invention, may be clearly understood and
readily carried into practice we will proceed to describe the Drawings
hereunto annexed.
plate removed; and Figure 3, a side view of a cooking stove or kitchen
range arranged and constructed in accordance with our improvements;
Figure 4 is a front elevation of the hood; Figures 5 and 6 being
sections thereof.

page_text: The hood a which is used for conducting the smoke and products of
combustion from the open fire (when the back flue is closed) is hinged
or jointed at a* to the back plate of the stove or range, and when drawn
forward, as shewn in Figure 6, sufficient space is left between the
bottom edge of the hood plate a and the upper surface or hob of the
stove to allow the plate which covers the fire (to form a close stove)
to be slid back, and thus close and cut off the draught from the bottom
and back flues, thereby converting the stove into an open fire-place with
draught passing direct to the chimney.
The hood a is advantageously formed in two parts a, a', the outer
part a when pulled out acting by means of studs a² to pull out the
inner bottom plate a¹ which is suspended on studs a³ so as to form a
clear passage to the chimney, but the construction and arrangement of
the hood a may be varied.
fit "
The hood a when closed (with the fire-plate or cover b drawn forward
over the fire) to form a close cooking stove, as shown at Figures 1 and 3,
falls close up against and level with the back plate of the range, thus
affording increased hob space to the stove.
Another part of our improvements consist in so forming the boiler c
and arranging the flues, as shown in Figures 2 and 3, that the split
draught passes down the flues c¹ formed between the fire-place A and
the boiler c (or boilers), thence between the top ends of the oven d and
the bottom of the boiler c which is curved off, as shown, for this purpose,
returning below the oven d where the split draught meets and passes
up the back of the oven d and stove to the chimney e. The heat is by
this arrangement applied in the most advantageous manner for heating
the hot plate boiler, and oven space being also economised.
The improved hood a may be applied to ranges and kitcheners of various
constructions.
Having thus described the nature of our Invention and the manner
of performing or carrying the same into practice, what we claim is,―
First. The improved arrangement and construction of the hood a, a¹,
of a cooking stove or kitchen range arranged to act, substantially in the
manner and for the purposes herein-before described and represented in
the Drawings hereunto annexed.
Secondly. We claim the improved arrangement and combination of
the flues, boiler (or boilers), and oven of cooking stoves or kitchen.

described and represented in Figures 2 and 3 of the Drawings hereunto
annexed.
In witness whereof, I, the said Alexander Paul Hutchison, have
hereunto set my hand and seal, this Fifth day of January, in
in the year of our Lord One thousand eight hundred and
seventy-six.
