We, HUGH STEVEN of the firm of McDowall Steven & Co., Ironfounders, Milton
Iron Works, Glasgow, and JAMES WALKER, Foreman at said Works, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to improvements in kitcheners or cooking ranges of the
kind known as convertible ranges which are adapted to be used as open fire
ranges on removing the fire cover and opening up a flue piece on the hob at
the rear of the fire and as close fire ranges on replacing the fire cover and flue
piece.
In a modification in which the flue piece is composed of a single casting in the form
of a cover plate with vertical sides and is adapted to rest upon the hob with the
cover plate lying horizontally when the fire is open and lying vertically against the
back coving or skirting or the uptake with the vertical sides within the uptake
when the fire is closed, the use of pivot pins directly connecting the flue piece to
the uptake or back of the range is dispensed with and a link or strap jointed to each
side of the flue piece is connected at its inner end to a stud or pin in the uptake piece
entering a slot in the link or strap. The links or straps whilst retaining the flue piece
when set in either its open or closed position freely permit of its tilting or being
turned through a vertical arc.
In another modification the movable flue is composed of two vertical sides connected
together but having no cover plate attached to them the flue piece being adapted to
slide horizontally out and in through an opening in the coving or back of the range
leading into the chimney flue: or two such flue pieces may be fitted one within the
other so that they may be telescoped to give greater or less length to the movable flue
which is drawn forward more or less on the hob at rear of the fire on opening the
fire and pushed back into a suitable recess in tho uptake or chimney flue on closing
the fire. A flap hinged to the back part of the range just over the flue opening
hangs vertically and serves to close the orifice leading into the uptake when the
fire is closed. and on the flue piece being drawn forward it is thereby tilted

page_text: to the horizontal position in which it rests upon and forms. a cover to the flue
piece.
In still another modification adapted more particularly for use in cases in which the
depth of the hob from the rear of the fire to the coving is very great, the hinged flap
forming the cover of the flue piece is composed of two or more pieces hinged or
similarly connected together so that the forward portion or portions may be doubled
upon the rear portion in adapting it to cover the outlet orifice which is in such cases
usually of such depth that the cover plate when doubled closes it. The sides
of the flue are composed of plates which are hinged vertically one on each side
of the outlet orifice leading to the chimney so that they may be turned in a
horizontal are to lie across the outlet orifice when the flue is closed and to extend
forward at right angles to the back coving and support the cover plate or hinged flap
when the flue open.

page_text: Improvements in Cooking Ranges.
We, HUGH STEVEN of the firm of McDowall Steven & Co., Ironfounders, Milton
Iron Works, Glasgow, and JAMES WALKER, Foreman at said Works, 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 :-
Our Invention relates to improvements in kitcheners or cooking ranges of the kind
known as convertible ranges which are adapted to be used as open fire ranges on
removing the fire cover and opening up a flue piece on the hob at the rear of the fire
and as close fire ranges on replacing the fire cover and flue piece.
In a modification illustrated in front elevation by figures 1 and 2 and in transverse
section by figures 3 and 4 of the accompanying Drawings and in which the flue piece a
is composed of a single casting in the form of a cover plate with vertical sides 6 and is
adapted to rest upon the hob c with the cover plate lying horizontally when the fire is
open as seen at figure 1 and standing vertically against the back coving or skirting or the
uptake with the vertical sides 6 within the uptake a when the fire is closed as seen at
figure 2 the use of pivot pins directly connecting the flue piece a to the uptake or back d of
the range is dispensed with and as now particularly seen at figures 3 and 4 a link or
strap e journalled to each side 6 of the flue piece a is employed in lieu thereof, the said
straps being connected at their inner ends to the uptake by studs or pins ffixed in the
sides of the uptake and working through or in slots g in the links or straps-These
links or straps e whilst retaining the flue piece a when set in either its open position
as at figure 3 or in its closed position as at figure 4 freely permit of the flue piece
being tilted or being turned through a vertical arc to assume either position.
In another modification illustrated in elevation by figures 5 and 6 and in transverse
section by figures 7 and 8 the moveable flue is composed of two vertical sides b con-
nected together as at b¹ figure 6 but having no cover plate attached to them the flue
piece being adapted to slide horizontally out and in through an opening in the
coving or back d of the range leading into the chimney flue or as illustrated by
figures 7 and 8 two such flue pieces b 62 may be fitted one within the other so that
they may be telescoped to give greater or less length to the moveable flue which
is drawn forward more or less on the hob to give an open fire and pushed
back into a suitable recess in the uptake or chimney flue on closing the fire.
The parts 63 of the flue pieces have slots h made in them through which pins i fixed in
the parts b pass these pins at the same time acting to connect the parts together and
as guides in drawing out the parts 6. A flapj hinged to the back part of the range
just over the flue opening hangs vertically and serves to close the orifice leading into
the uptake d when the fire is closed. On the flue piece being drawn forward the flap
is thereby tilted to the horizontal position as at figure 6 in which position it rests upon
and forms a cover to the flue pieces 6 6. Instead of the flap j being so hinged it
may as seen in elevation at figures 9 and 10 and in transverse section at figures 11

page_text: and 12 be arranged to slide in vertical slotted guides I formed on or secured to the
sides of the uptake d the flap being drawn downwards and moved outwards through
an arc when it is desired to open the fire as at figures 9 and 11 and moved inwards
and upwards through an arc when it is desired to close the fire as at figures 10
and 12.
In still another modification illustrated in elevation at figures 13 and 14 and in
transverse section at figures 15 and 16 of the drawings and which is adapted more
particularly for use in cases where the depth of the hob c from the rear of the fire to
the coving is very great the hinged flap j forming the cover of the flue piece is
composed of two or more pieces hinged or similarly connected together as at ¹ so that
the forward portion or portions may be doubled upon the rear portion as seen by
figures 14 and 16 in adapting the range for a close fire. The sides b of the flue with
this arrangement are composed of plates which are hinged vertically one on each side
of the outlet orifice leading to the chimney so that they may be turned in a horizontal
arc to lie across the outlet orifice when the flue is closed as at figures 14 and 16 and
to extend forward at right angles to the back coving and support the cover plate or
hinged flap when the flue is open as at figures 13 and 15.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
--
1. In a cooking range connecting a flue piece composed of a single casting to the
uptake or back of the range by links or straps substantially as described with reference
to figures 1 to 4 of the annexed drawings.
2. In a cooking range a moveable flue consisting of two vertical sides each'of which
is or may be composed of two or more parts capable of extension to give greater or
less length and a top flap or cover hinged to or sliding in guides on the back part of
the range over the flue opening the whole operating substantially as and for the
purpose set forth with reference to figures 5 to 12 inclusive of the appended
drawings.
3. In a cooking range an adjustable flue consisting of two vertically hinged sides
and a flap or cover composed of two or more parts hinged or jointed to and capable of
being folded on each other substantially as and for the purposes set forth with reference
to figures 13 to 16 of the appended drawings.
