I, ROBERT NISBET of the Star Foundry (Kinning Park) 100 Portman Street
Glasgow in the County of Renfrew, Ironfounder and Manufacturer, trading
under the style of A. Nisbet and Son do hereby declare the nature of my invention
for IMPROVEMENTS IN COOKING RANGES to be as follows, namely:-
The formation of a portable and self adjusting flue (for the purpose of applying
it to ordinary close fire ranges) which may be used when the cooking range to
which it is applied is required as an open fire range, or, when it is not so required,
may be placed in a receptacle at the back of the range.
Briefly described, this portable flue is hinged to the fire cover, and all its
alternations, from "open fire" to "close fire" or vice versa are effected by simply,
lowering it, pushing it back, pulling it forward and tilting it upwards by means of
handles held in the hands of the operator.
The appearance, and construction of, and mode of using this portable flue may be
thus described.
It is rectangular in form, and resembles a broad but shallow box, made of iron
and composed of two or more parts, the lower portion having upright flanges on the
right and left sides only, the upper part, cover or lid being similarly made, with
two flanges inversely placed to the lower ones and fitted, within, outside or
partially upon, the flanges of the lower part of this box flue, and so constructed
that they will slide, one within the other and by so doing contribute to lengthen
the flue.
The lower portion of this box shaped flue is connected with the fire cover, or its
continuation, by means of a hinge, or hinges, and when this flue is not required it
may be raised by means of this hinge and handles attached to the flanges of the
box flue and tilted into an upright position against the back of the range where it
is, or may be enclosed in a recess provided for it within, upon, or attached to the
back cove plate of the same during the period when the range is not required with
an open fire.
The further purpose or purposes to be served by the handles just named, is, or
are, that the box flue, coupled or hinged as described to the fire cover, may be
propelled backward or forward by means of them..
The hinge arrangement, or arrangements, being horizontally related to and
parallel with the hot plate and the front parts of the range.

COMPLETE SPECIFICATION.
I, ROBERT NISBET, of the Star Foundry (Kinning Park) 100 Portman Street,
Glasgow in the County of Renfrew Ironfounder and Manufacturer, trading
under the style of A. Nisbet and Son, do hereby declare the nature of my 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, namely :-
>
A plan by which I am enabled to convert ordinary close fire ranges into
combined open and close fire ranges and consists in the particular formation of,
and the particular manner of applying a portable iron flue to an ordinary close fire
range by which the range may be used with an open fire when so required and
at other times the portable flue may be conveniently placed at the back of the
range.
"
This portable flue is hinged to the fire cover and placed erect at the back of the
range and the several alternations from "close fire" to "
open fire or open fire "
to close fire" are effected by first lowering the flue upon the fire cover and
pushing the two parts backward, thus producing an open fire arrangement, or
thereafter pulling them forward and tilting up the flue, when it is again a "close
fire range," the manipulation being assisted by handles held rigidly in the hands of
the operator and attached to the flue. These handles are not rigidly attached to the
flue but somewhat loosely so that they will work freely and with a kind of swivel
action when the flue is lowered, tilted, or otherwise moved with them.
The appearance, and construction of, and mode of using this portable flue may
be thus described.
It is rectangular in form and resembles, when in use, a broad shallow box, made
of iron, and is composed of two or more parts, the one forming the top and the
other part forming the bottom of the flue: the lower portion having upright
flanges on the right and left sides only, and the upper part, (cover or lid) being
similarly made with two flanges inversely placed to the lower ones and made so as
to fit within, outside, or partially upon the flanges of the lower part of the flue.
These two parts are so constructed that they will slide, one within the other and
by so doing contribute to lengthen or shorten the flue as required.
The flue, as just described is illustrated by Figures 1, 2, 3 and 4 in the
accompanying series of diagrams. Fig. 1 gives the general appearance of it with
the two flanged parts adjusted so as to resemble a broad but shallow box, with open
ends. Fig. 2 shews the lower part of the flue, and Fig. 3 the upper part of it, and
Fig. 4 shews the upper part drawn forward beyond the lower one, so as to elongate
the flue.
Although it is made of two flanged parts, the one part sliding loosely within the
other, they each control the other by means of notches and catches arranged upon
or against the flanges so that neither part can exceed its proper limits backward or

page_text: forward and when the flue is tilted into an
rectangular and box-like form.
upright position, it retains its
These notches and catches are shewn in Figs. 2 and 3 and in several of the other
illustrations by parts marked A, B, C and D. The parts marked A and B limit the
forward movement of the flue cover, whilst C and D restrain and limit the back-
ward movement of the same and so connect the upper and lower parts of the flue
that when the latter is tilted into an erect position the two parts of the flue
cannot fall asunder.
The circular aperture in the upper part of the flue, and marked E in Figs. 1. 3. 4. 7
is not an essential part of the construction but is intended for the insertion of a kettle
or other vessel and may be closed by the circular part, or parts, of the fire cover (F
or G) as required, or the upper part of the flue may be made without any such
aperture.
The lower portion of this flue is connected with the back part of the fire cover,
(or the continuation of the latter) by means of clasps or hinges which materially
assist the lowering or raising of the flue, the process being effected with handles
attached to the side flanges, or other parts of the box flue.
"
An upright recess is formed at the back of the range, within, upon or attached to.
the back " cove plate or "skirting" of the range, and is designed to enclose,
(wholly or in part) the flue, during the period when the range is not required with
an open fire.
The clasps or hinges previously referred to are formed by the projections
marked H. H and J. Jon Figs. 2 and 5 and are shown in their proper positions,
complete for working, by K. K on Figs. 6 and 8.
The handles before named, and which are, or may be, attached, by means of
rivetting, screwing or other mode, or modes, of fastening them on, either
permanently or otherwise, to the box flue, and on any convenient part thereof, are,
for purposes of example only, shewn in various positions in Figs. 1. 2. 4. 6. 7. 8
and 9.
In Fig. 6. the box flue is shewn tilted upwards and the handles in the positions
suited to the movement (as well as to that required for lowering the flue from its
recess) and Fig. 7 shews the flue lowered and lying upon the fire cover preparatory
to being pushed back into the aperture marked L. L.
The further purpose, or purposes, to be served by the handles is, or are, the
moving backward or forward of the box flue in its recumbant position according as
the flue is required or removed.
In Fig. 9 the box flue is represented as pushed back into the aperture
marked L L in Fig. 7.
The recess, formerly described, is indicated by M. M in Figs. 6. 7. and 9 and
Fig. 8 is a representation of the flue in its normal and upright position as enclosed
in this recess.
The binge arrangement or arrangements (otherwise called clasps) before described
are horizontally related to, and parallel with the hot plate and the front parts, or
face, of the range, and is, or are, fairly shewn in Figs. 6 and 8 where it, or they,
serve the purpose of uniting the upright flue to the back part of the fire cover.
The principal purpose, or purposes, to be served by this bingeing of the flue to
the fire cover is, or are, that the flue may be lowered from, or raised into, its erect
position with ease, and when lowered may act simultaneously with the fire cover in
the necessary backward or forward movements of the same, and, further, may guard'
the apparatus by this mode of coupling it against accidental dismemberment or
dislocation.
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
First. For a portable flue, composed of two or more parts which slide, one
within the other, as already described and drawn herein.

page_text: Secondly. For the hingeing of the said flue to the fire cover of the range in such a
manner, or similarly to the plan, as herein described and drawn, and

Thirdly. For handles attached to such portable flue, of the character and in the
manner, as well as for the purposes herein before described and illustrated.
