IMPROVEMENTS IN KITCHEN RANGES
Year: 1876

page_text: LETTERS PATENT to John Shaw, of Glasgow, in the County of Lanark, North
Britain, for the Invention of "IMPROVEMENTS IN KITCHEN RANGES."
PROVISIONAL SPECIFICATION left by the said John Shaw at the Office of
the Commissioners of Patents on the 20th June 1876.
JOHN SHAW, of Glasgow, in the County of Lanark, North Britain. " IMPROVE-
MENTS IN KITCHEN RANGES."
This Invention, which relates to improvements in kitchen ranges, consists in
constructing the plates which extend along the back of the range with a moveable
portion capable of being turned upwards on a hinge joint, so as to project over or
partly over the fire-place. The said moveable portion is provided with sides, each
of which is constructed in two parts, the separate portions being so hinged to the
back plates of the range that when the moveable part is lifted upwards the sides
will of themselves turn outwards. By means of this arrangement an opening or
flue may, when desired, be made through the back plates of the range, so as to
communicate with the main flue, which opening constitutes a ventilating flue,
through which the effluvia arising from cooking on the close range pass off into the
main flue, and are not disseminated through the kitchen as heretofore.
The plate covering the fire-place is also removeable, by which means the range is
adapted for employment as an open range, with or without the ventilating flue, or
as an open fire-place, in which latter case the products of combustion pass off
through the ventilating flue, suitable dampers being provided to regulate the
draught.

"IMPROVE

page_text: constructing the back wall or plate extending (behind the fire-place) from end to end
of the range, with a moveable portion capable of being turned upwards on a hinge
joint, so as to project over or partly over the fire-place. The moveable portion is
provided with sides, so that when it is lifted upwards an opening or flue is made
through the back wall or plate of the range, and communicating with the main flue
thereof. This opening constitutes a ventilating flue, through which the effluvia
arising from cooking on the close range pass off, and are thus not disseminated
through the kitchen as heretofore.
The plate covering the fire-place of the range is also removeable, so that the
close range may be converted into a range with an open fire-place when desired, the
products of combustion in this latter case passing off through the ventilating
flue.
And in order that my said Invention may be properly understood I now proceed
more particularly to set forth the system, mode, or manner, in or under which the
same is or may be used or practically carried into effect, reference being had to the
annexed Sheet of Drawings and to the letters and figures marked thereon, that is
to say:―
On the Sheet of Drawings hereunto appended Figure 1 is a front elevation of a
kitchen range with the improvements constituting my said Invention illustrated in
conjunction therewith.
Figure 2 is a transverse section through the fire-place of the range, whilst
Figure 3 is a plan of that part of the range in which the fire-place is situated.
As shewn by these Figures the back wall or plate A of the range is formed with
a moveable portion B which is hinged to the back wall A at x, Figures 2 and 3, 80
as to be capable of turning upwards and projecting over or partly over the fire-place
in the manner illustrated at Figure 2.
In conjunction with the moveable part B side plates or cheeks C are provided,
these being hinged to angle iron or other plates D secured to the back wall A, or
instead of the plates D projecting portions may be cast or formed on the back wall
itself for this purpose. The lower hinge w of cach of the side plates or checks C is
preferably placed further out from the back wall A than the upper hinge v, as is
shewn on the Drawings, in order that when the plate B is lifted the side plates C
may of their own accord swing outwards, so as, with the top plate B, to enclose a
spaco which constitutes a flue leading from above the fire-place of the range into
the main flue at the back thereof. This flue so made forms the ventilating flue
herein-before referred to, through which the effluvia arising from cooking on the
close range pass off into the main flue, and are thus not disseminated through the
kitchen, and from thence through other parts of the house, as heretofore.
In order to facilitate cooking on the range with wide pans or other vessels which,
on account of the area covered by them might not be capable of being introduced
into the space enclosed between the sides of the ventilating flue, each side cheek or
plate C is formed in two parts, the lower one of which is capable of being folded
inwards and upwards on hinge joints, whereby space for such wide pans or other
vessels is provided. The moveable plate B may, when in its lowered position
terminate at the lower edge of the back wall A, in which case it covers in the side
cheeks or plates C, or, as shewn on the Drawings, the moveable plate B may be
terminated short of the lower edge of the back plate and a separate moveable
plate E, Figure 1, employed to cover in the exposed parts of the side cheeks or
plates C, or the said plates, at the parts projecting under the lower edge of the
moveable plate, may be left uncovered.
When the ventilating flue is closed, as herein last set forth, the damper at y in
the main flue is or may also be closed, thereby diverting the products of combustion
in the fire-grate through the other flues u, t, and 8 of the range.
The flue composed of the plates B and C besides acting as a ventilating fluc and
carrying off the effluvia arising whilst cooking on the close range also enables the
range to be used with an open fire, when desired, by acting as a vent or flue,
through which the products of combustion in the fire-grate may pass off, the

page_text: plate F covering the fire-place being removeable, as in the ordinary close range.
Figures 4, 5, and 6 illustrate respectively in part front elevation, part plan, and
part transverse section, the range with the fire-place open.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner, in or under which the same is or may
be used or practically carried into effect, I would observe in conclusion that what I
consider to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is,-
First. Providing kitchen ranges with a ventilating flue or opening, substantially
as and for the purpose herein-before described with reference to Figures 1, 2, and 3
of the Drawings hereunto annexed.
Second. Adapting close kitchen ranges for employment as open ranges or as open
fire-places by providing a flue for the passage of the products of combustion from
the open fire-place into the main flue of the range, substantially as herein-before
described with reference to Figures 4, 5, and 6, of the accompanying Drawings.
In witness whereof, I, the said John Shaw, have hereunto set my hand and
Beal this Fifteenth day of December One thousand eight hundred and
seventy-six.
JOHN SHAW. (L.S.)
