page_text: Improvements in and relating to Stoves and Cooking Ranges.
We, JOHN NICOL MITCHELL, Manager, and WILLIAM MORRISON, Foreman,
both of Parkhouse Iron Works, Falkirk, in the County of Stirling, North Britain,
do hereby declare the nature of this invention to be as follows:
It relates to Stoves and Cooking-ranges and has for its objects; 1st to adapt
them for being used with a closed top to the fire or an open one alternately as
required; 2nd to adapt them for use with a travelling flue for the fire which will
not obstruct the back or boiler flue; 3rd to adapt the metal case of a back flue or
flues for operating part or parts of the said travelling flue; 4th to simplify the
damping of the back flue or flues; 5th to increase the available hob space of a
stove or range; 6th to adapt the flue screen for being used as a grid, a trivet, or
bracket a pudding or toasting stand.
In carrying out one modification of this invention, a portable flue of rectangular
or other shape is fitted loosely within an aperture in that back plate of the range
or stove which is nearest to the fire. This back plate is either a Cove" plate or
one side (preferably the front one) of a metal chimney.
*
This portable flue is adapted for being moved backwards and forwards within
the said aperture. It can be drawn forward to the back of the fire space when the
latter is uncovered or pushed back through the aperture into the flue space behind
it when the fire space is covered.
Behind the said aperture an upright metal case is fixed containing one or more
vertical flues and dampers. In this modification the metal flue case is smaller
from right to left in its dimensions than the right to left breadth of the portable
flue, and the rear side plates of the latter extend along the right and left sides of
the metal case so that when the travelling flue is pushed completely back the
metal case is partly enclosed within a cut-away space in the roof of the travelling
flue. A sliding plate or horizontal shutter is fitted within guides upon the roof
plate of the flue and as the portable flue is drawn outwards through the aperture
this sliding plate is pushed back by means of a stop or stops which abut against
the chimney plate until the sliding shutter covers over the cut-away space in the
roof. When this fluo with the shutter is again pushed back the moving plate
abuts against the metal flue case and slides upon the roof plate as the flue is
pushed to its full extent backward.
Another modification of the invention comprises the aforesaid travelling flue
which is made in two principal parts, telescoped one upon the other and adapted
for being pushed back through the aforesaid aperture into a very small back space
between the metal case before named and the plate containing the aperture.
When this travelling flue is drawn out to its full extent a stop (or stops) unite the
two parts thereof together and prevent the hinder part being drawn too far

page_text: forward or becoming detached from the front part, and when it is pushed back
against the metal flue case its progress is arrested and the travelling flue is tele-
scoped, one half of it upon the other within the narrow space between the flue
case and the plate containing the aperture. If an extra long travelling flue is
required the cut-away part of the roof before named and its sliding damper are
associated with the hinder half of this telescoped flue, and the cut-away part is
sometimes in the foremost half also.
When the travelling flue is pushed into the back flue space its front opening is
covered by means of a perforated plate furnished with hooks adapting it for
being attached in a vertical attitude to the flue as a cover; or in a horizontal
position as a grid above above the fire when the flue is drawn forward; or it can
be attached similarly, in a horizontal position to the front of the fire breast, top
or bottom, as a hanging trivet or pudding stand; a separate interfitting part is
sometimes added to this perforated plate adapting it for use as an automatic
toasting appliance.
Each vertical flue within the aforesaid metal case is furnished with a damper
and handle which protrudes through the chimney or cove plate above the travelling
flue so that the back flue or flues can be closed or opened independently of this
travelling flue.
As one result of concentrating all the back flues of the stone or range within the
metal chimney in line with the fire back the hob plate can be extended further
back than ordinary.

We, JOHN NICOL MITCHELL, Manager, and WILLIAM MORRISON, Foreman,
both of Parkhouse Iron Works, Falkirk, in the County of Stirling, North Britain,
do hereby declare the nature of this invention and in what manner the same
to be performed, to be particularly described and ascertained; in and by the
following statement:-
It relates to Stoves and Cooking-ranges and has for its objects; 1st to adapt
them for being used with a closed top to the fire or an open one alternately as
required; 2nd to adapt them for use with a travelling flue for the fire which will
not obstruct the back or boiler flues; 3rd to adapt the metal casing of a back flue or
flues for operating part or parts of the said travelling flue; 4th to simplify the
damping of the back flue or flues; 5th to increase the available hob space of a
stove or range; 6th to adapt the flue screen for being used as a grid, a trivet, or
bracket, a pudding stand or toasting stand.
The invention will be better understood if reference is made to the accompanying
drawings in which:-
:-
Figures 1 and 2 are sectional views shewing parts of a stove or range in
elevation illustrative of this invention.
Figures 3 and 4 are side views in perspective shewing a portable flue apart from
the stove and other parts comprised in this invention.
Figures 5 and 6 are views in perspective of parts comprised in this invention.

page_text: Figures 7 to 11 are elevations and plans of parts comprised in this invention.
Similar letters of reference and mumerals throughout the illustrations indicate
corresponding parts.
In carrying out one modification of this invention as shewn in Figures 1 and 2
a portable flue A of rectangular or other shape is fitted loosely within an aper-
ture contained in that back plate 13 of the range or stove which is nearest to
the fire place C. This back plate B is either a "Cove" plate, "Skirting" or
one side (preferably the front one) of a metal or other chimney.
This portable flue A is adapted for being moved backwards and forward within
the said aperture 61 and chimney; the latter being marked B D, & in the draw-
ings. It can be drawn forward to the back of the fire space C when the latter is
uncovered as shown in Fig. 2 or pushed back through the aperture 61 into the
chimney or flue space D behind the said aperture when the fire space C is covered
as shewn in Fig. 1.
Behind the said aperture band within the chimney D an upright metal case E, el
is fixed containing one or more vertical flues each flue being fitted with a damper F.
In this, and each modification of the invention illustrated herein, the metal flue
case E, el is smaller from right to left (front view) in its dimensions than the
right to left breadth of the portable flue A, (similarly to that marked, L, in Fig. 9)
and the rear side plates a' of this flue extend along the right and left sides of the
metal case E, el so that when the travelling flue A is pushed completely back as
shewn in Fig. 1 the metal case E, el is partly enclosed within a cut-away space a
in the roof of the travelling flue A. A sliding plate or horizontal shutter a
Figs. 1 to 4 is fitted within guides or strips a upon the roof plate a³ of the 'flue A
and as this portable flue is drawn outwards through the aperture in the front
chimney plate B, this sliding plate a is pushed back by means of a stop or
stops which abut against the back of the chimney plate B which will not let it
pass until this sliding shutter is forced back and covers over the cut-away space a²
in the flue roof. When this flue A with the shutter a is again pushed back into
the chimney D the loose plate a abuts, in its backward transit against the plate e¹
of the flue case E and then as the flue A travels still further backward this loose
shutter is forced upon a portion of its roof plate a shewn in Fig. 1.
A perforated plate G Figs. 1 to 5, furnished with integral and detached hooks g¹
and H (Figs. 1, 2 and 6) adaping it for being attached either to the flue A or the
fire breast is designed to serve the various purposes of a screen or cover to the
front of the flue A as shewn in Figs. 1 and 3; of a grid above the fire as shewn in
Fig. 4 and indicated by dotted lines in Fig. 10; of a pudding stand or bracket
when fixed to the front of the fire bars J by means of the hooks Figure -1; of a
trivet when similarly fitted upon the hooks Figs. 1 and 2; also of a toasting
appliance when fitted in front of the fire bars by means of the hooks interfitting
within the slots g² (Fig. 5) as indicated by dotted lines in Fig. 2. A slot a' or 15
formed in the front end of the travelling flue as shewn in Figs. 2, 8, 9 and 11
enable the plate G, Fig. 5 to be fixed in front of the said flue as shewn in Figs. 3
or 4; the hook gl, Figs. 1 and 2 or ¹ Fig. 6 being inserted in the said slot a³.
The grid G, Figs. 4 and 5, can be fitted by means of the notch g³ upon either of
the hooks 2 Fig. 6; and in Fig. 1 the hook g' is indicated in elevation as occupying
the eye or slot a³.
Another modification of the invention relates to an extra long travelling flue,
constructed similarly to the one already described but made in two principal
parts Land telescoped one upon or over the other as shewn in Figs. 7, 8 and 9.
It is adapted for being telescoped into a very small compass comparatively (see
Fig. 9) and pushed back through the aperture into the chimney space 1) between
the plate B and the flue case E, also along the right and left sides of the latter.
The front part L has two cut-away parts 2 and the hinder part has two stop
pins for moving within the cut away parts 72. When the two parts L and of
this flue are put together as shewn in Figs. 7. aad 8 the stop pins 13, inserted
within the cut away spaces 12 serve to unite together the telescoped parts of this

page_text: flue. A cut away part such as a² Figs. 3 and 4 is formed in the part and a sliding
damper such as a Fig. 4 is associated therewith similarly to Figs. 1 to 4 the
parts are bevilled so that a bevilled back edge of L may enter beneath them and
cause the plate at, l, to ride upon the top of L as shewn in Fig. 9.
When this travelling flue L, is drawn out to its full extent as shewn in
Figs. 7 and 8 the parts 12, 13 unite its front and back parts together and prevent
their inadvertent dismemberment; the rear stops Figs. 7 to 9 prevent the
hinder part being drawn out of the aperture 6¹ and the rear stops 78 upon the
sliding plate a, 16, prevent that plate being drawn through the opening wha
the flue is in use. These rear stops 7 and 78 abut against the plates B, and e¹
in their forward and backward movements. The rear stops are sometimes
made to project upwards, like those marked a¹0 Figs. 1 to 4 as this form enables A
or 1 to withdrawn through the aperture if they are suitably manipulated
by tilting.
A cut away space a² Figs. 3 and 4 is sometimes made in the part L as well as
in that marked 14.
Another modification of the invention is shewn in Figs. 10 and 11 and relates
to a telescoped flue piece L, similar to L, except that this flue is minus the
cut-away part a² and sliding plate a³, a; this flue is designed as a medium sized
one.
When either of the moveable flues L, 1, or L, have been drawn out upon the
hob plate K to their full extent as shewn in Fig. 7 the front portion can be pushed
back for the length of the slot or cut away past 2, without moving the hinder
part (or) after which either of the telescoped combinations L, 1, or L, 14 can
be still further moved back if the current up the flue is strong whilst the fire
space C remains uncovered.
The fire cover & Figs. 1 and 2 can be pushed back into the recess as shewn in
Fig. 2.
The perforated plate G and hook H are designed for combination with any or
all of the flues A; L, l, or L, herein described.
Each vertical flue within the aforesaid metal case E is furnished with a
damper F and handle f¹ which protrudes through the chimney (or "Cove") plate
above the travelling flue A or L so that the back flue or flues within the case E
can be closed or opened independently of the said travelling flue or flues.
As one result of concentrating all the back flues of the stove or range within a
chimney and metal case (indicated herein by D and E) in line with the fire back,
the hol plate K can be extended further back than ordinary.
We are aware that previous to our invention telescopic and other moveable
flues with and without cut-away parts and dampers for covering over said parts;
also metallic boiler flues with dampers enclosed within chimnies above the level
of the hob; also hook-on brackets trivets and toasting appliances have been made
and combined with stoves and ranges; it will therefore be understood that we do
not claim these things broadly as our invention.
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
we claim is:-
First, in a stove or range the combination therewith of the flue devices all
substantially as herein described with reference to Figures 1 to 6 of the drawings
or any mere modification thereof for the purposes specified.
Second, in a stove or range the combination therewith of the flue devices all
substantially as herein described with reference to Figures 1 to 4 of the drawings
or any mere modification thereof for the purposes specified.
Third, in a stove or range the combination therewith of the flue devices all
substantially as herein described with reference to Figures 5, 7, 8 and 9 of the
drawings, or any mere modification thereof for the purposes specified.
Fourth, in a stove or range the combination therewith of the flue devices all

page_text: substantially as herein described with reference to Figures 5, 10 and 11 of the
drawings or any mere modification thereof for the purposes specified.
