page_text: I, JOHN EDWARD GIBSON, of the Camelon Iron Works, Falkirk, in the County
of Stirling, North Britain, Managing Partner, do hereby declare the nature of this
Invention to be as follows, that is to say:-
My said Invention has for its object to improve the construction of certain parts
of cooking ranges and stoves, so that such apparatus may be easily and conveniently
converted from a close-fire range or stove to one with an open fire, or vice versa,
the improved parts being of simple and economical construction and not liable to
become deranged.
In carrying out my Invention the range or stove is made with the usual vertical
flue pipe rising upwards from the back of the fire box. This flue pipe is made
with an opening in front at the bottom and above the hob, which opening, when
the parts are arranged for a close fire, is closed by a vertical plate attached to or
cast in one piece with a narrow horizontal plate or slip extending forwards from
the front plate. The usual fire cover extends from the front edge of the horizontal
slip to the front of the firebox; and this fire cover is made with pins or hooks
projecting downwards at its back edge so as to enter eyes formed at the front edge
of the horizontal slip. The parts so far described when combined with the usual
parts of a close-fire range or cooking stove are all that are required for the close-
fire condition of the apparatus. For the purpose of converting the apparatus into
an open-fire range or stove there is provided a flue box, which when the parts are
arranged for a close fire is beneath the horizontal slip and the back part of the fire
cover. The flue box consists of vertical sides connected to each other by transverse
bars at the top and bottom, and it is guided so as to be capable of moving vertically,
its bottom being connected by a link or otherwise to a lever by means of which
the flue box is raised or lowered. The lever passes through the front vertical plate
of the range or stove and turns on a fulcrum pin fixed in projections on the inner
side of that plate whilst a front arm or bar is fitted to it with a socket or other
joint so as to be removable when not in use for raising or lowering the flue box.
When converting the close-fire to the open-fire arrangement the fire cover is pushed

backwards along with the horizontal slip at the back of it.
then closes the opening from below into the bottom of the flue pipe, whilst the
front opening is opened in consequence of the vertical plate being pushed back with
the horizontul slip to which it is attached. The flue box is next raised, and in

passage for fire draught into the back flue pipe. The flue box is supported in its
raised position by its lever being pushed backwards so as to rest on a bracket
provided for the purpose; or it may be secured in any other convenient way. For
changing from the open-fire to the close-fire arrangements the operations are
simply reversed.
A rack and pinion or other analogous appliance may be used for raising and
lowering the flue box.
The improvements are applicable to ranges and stoves having built flues as well
as to those having iron flue pipes.

page_text: I, JOHN EDWARD GIBSON, of the Camelon Iron Works, Falkirk, in the Countý
of Stirling, North Britain, Managing Partner, 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, that is to say :-
My said Invention has for its object to improve the construction of certain parts
of cooking ranges and stoves, so that such apparatus may be easily and conveniently
converted from a close-fire range or stove to one with an open fire, or vice versâ,
the improved parts being of simple and economical construction and not liable to
become deranged.
:
In carrying out my Invention the usual flue pipe is formed with an opening in
front at the bottom which opening when the parts are arranged for a close fire is
closed by a vertical plate attached to or cast in one piece with a narrow horizontal
plate or slip formed with eyes into which pins or hooks formed on the back edge
of the usual fire cover enter. To convert the apparatus into an open fire range or
stove there is provided a flue box which, when the parts are arranged for a close
fire is beneath the horizontal slip and the back part of the fire cover. After the
fire cover, horizontal slip, and vertical plate, are pushed back thus closing the
opening from below into the flue pipe and opening the opening in front the flue
box is raised by means of a lever connected to its bottom and passing out through
the front plate of the range. The flue box in rising lifts the fire cover which then
forms a cover to it.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing a cooking range as fitted with my
improvements.
Figure, 1, on the accompanying sheet of explanatory drawings is a perspective
view showing the range as arranged for an open fire. Figures, 2, and 3, are
transverse sections showing the close and open fire arrangements respectively. In
these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
The range or stove is made with the usual vertical flue pipe, 4, rising upwards
at the back of the fire box, 5. This flue pipe, 4, is made with an opening in front
at the bottom and above the hob which opening, when the parts are arranged for
a close fire, is closed by a vertical plate, 6, having attached to it or cast in one
piece with it, a narrow horizontal plate or slip, 7, extending forwards from the
front plate, 6. The usual fire cover, 8, extends from the front edge of the horizontal
slip, 7, to the front of the firebox, 5; and this fire cover, 8, is made with pins or
hooks projecting downwards at its back edge so as to enter eyes, 9, formed at the
front edge of the horizontal slip, 7. The parts so far described when combined
with the usual parts of a close-fire range or cooking stove as shown are all that are
required for the close-fire condition of the apparatus. For the purpose of converting
the apparatus into an open-fire range or stove there is provided a flue box, 10,
which when the parts are arranged for a close fire, (figure, 2,) is beneath the

page_text: horizontal slip, 7, and the back part of the fire cover, 8.
The flue box, 10, consists
of vertical sides, connected to each other by transverse bars, 12, at the top and
bottom, its sides being guided in recesses formed for them in the hob so as to be
capable of moving vertically. The bottom transverse bar, 12, of the flue box, 10,
is connected by a link, 13, to a lever, 14, by means of which the flue box, 10, is
raised or lowered. The lever, 14, passes through the front vertical plate, 15,. of the
range or stove and bas a slot near its front end which works on a fulcrum pin
fixed in projections, 16, on the inner side of the plate, 15, whilst a front arm or
bar, 17, is fitted to it with a socket or other joint so as to be removable when not
in use for raising or lowering the flue box, 10. When converting the close-fire to
the open-fire arrangement the fire cover, 8, is pushed backwards along with the
horizontal slip, 7, at the back of it. The horizontal slip, 7, then closes the opening
from below into the flue pipe, 4, whilst the front opening is opened in consequence
of the vertical plate, 6, being pushed back with the horizontal slip, 7, to which it is
attached. The flue box, 10, is next raised, and in rising it lifts the fire cover, 8,
the pins being withdrawn from the eyes, 9, on the horizontal slip, 7. The fire
cover, 8, then forms a cover to the flue box, 10, and both form a direct passage for
the fire gases into the back flue pipe, 4. The flue box, 10, is supported in its raised
position by its lever, 14, being pushed backwards so as to rest on a bracket, 18,
provided for the purpose, or it may be secured in any other convenient way. For
changing from the open-fire to the close-fire arrangements the operations are simply
reversed.
A rack and pinion or other analogous appliance may be used for raising and
lowering the flue box. The fire box may be made with a firebrick back, 19, as
shown in figure, 2, or with a water heating box, 20, as shown in figure, 3.
The improvements are applicable to ranges and stoves having built flues as well
as to those having iron flue pipes.
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:
1-The constructing of a cooking range or stove so as to be convertible into a
close-fire or open-fire range or stove, by means of a part formed with vertical and
horizontal plates for respectively closing front and bottom openings in the flue
pipe, such part being combined with a flue box placed behind the fire box in the
close-fire arrangement and arranged to be raised along with the fire cover for the
open-fire arrangement substantially as herein before described.
.
2-The constructing of cooking ranges or stoves with a flue box and with a
space behind the fire box for the said flue box and with mechanism for raising or
lowering the flue box out of or into the space so as to form an open-fire or close-fire
arrangement substantially as hereinbefore described.
