Improvements in and relating to Fire-places.
We WILLIAM ROBB, Manager THOMAS SCOTT, Foreman, and LIVINGSTONE
RAE RUSSELL, Pattern Maker, all of Callendar Iron Works, Falkirk, in the
County of Stirling, North Britain, do hereby declare the nature of this invention
to be as follows:-
This invention relates to fire-places, chiefly those of stoves and cooking ranges
and has for its objects ;
1st. To combine with them portable flue appliances whereby they may be adapted
for use alternately with an open top to the fire or a closed one:
2nd. To close the top of the fire and entrance to the portable flue simulta-
neously:
3rd. To open the top of the fire and entrance to the portable flue simulta-
neously:
4th. To effect either of the above named opening or closing operations with one'
movement.
.
In carrying out this invention we make a portable flue of rectangular form
having a top plate and two sides, right and left, open from front to back and fit
this into an opening in the cove, skirting or chimney front immediately opposite to
the back of the fire, the hob forming the base of the said opening and a support
for the loose flue. The roof of this loose flue is partially cut away at the back and
a flap shaped like the cut-away space is hinged thereto and linked to the chimney,
cove or skirting so that when the flue is pulled out upon the hob this flap lies
horizontally and forms part of the flue roof and when the flue is pushed back into
the chimney the flap is held back and rises erect leaving the cut-away space open
for the gaseous proceeds of combustion to pass from the lower flues into the
chimney.
When this flue piece is pulled out upon the hob towards the fire back and the
cover is removed from over the fire the products of combustion pass through this
flue piece into the chimney thus constituting the apparatus an open fire one.
A plate is fitted within the flue piece and serves the purposes of a door for its
front aperture. We pivot this door plate on its right and left extremities to the
hob within the flue piece and furnish the back of it with one or more flanges so that
it may be forced into an upright position or suffered to fall backwards into a sloping
one for closing and opening the front aperture of the flue piece whenever the fire
cover is moved forward or backwards beneath the said door plate. There are
certain projecting parts upon the fire cover which engage with the back flanges
upon this door plate and force the latter into an upright position when the fire cover
is moved in a forward direction.
Instead of this door plate being made to fall backwards with its face uppermost
and in a sloping position within the flue piece; in which position the smoke can
pass over its face and blacken it; we sometimes cause it to fall forward with
its face upon the hob when the flue piece is moved outwards from the chimney.
In this latter position the smoke passes over the back of the door plate and the
face of it is kept bright and clean. To effect this latter movement of the door plate
it is pivotted, as before named, to the hob and compelled to fall forward when the
flue piece is projected from the chimney, by means of stops contained within the

page_text: flue piece which serve to retain the door in its upright position when the flue
is pushed back into the chimney and to press forward the upper edge of door plate
when the flue itself is moved forward. One or more sloping flanges are made on the
inner walls of the flue piece for partially lifting up this door plate when the flue
piece is pushed backwards. When the flue piece is fully inserted in the chimney
this door plate closes its front aperture, the fire cover closes the fire top and the
apparatus is a "close-fire" one.
The simultaneous operation of these flue accessories and fire-cover is effected by
means of a pivotted lever frame fixed to the hob, right and left, behind the loose
flue and is in close contact with the flue piece and the fire cover.
When the fire cover is pushed backwards, uncovering the fire, it presses back the
lower part of the pivotted lever frame and causes its upper parts to bear against
the rear end of the flue piece forcing the latter outwards from the chimney and
operating the roof flap and entrance door plate in the manner before described.
This last named movement effects the opening of all the parts necessary to adapt
the apparatus for open fire purposes. In order thereafter to close them the flue
piece must be pushed backwards when it presses against the upper part of the
pivotted lever frame and simultaneously forces forward the fire cover by means of
those parts of the lever frame which are below its fulcrum.

Improvements in and relating to Fire-places.
We, WILLIAM ROBB, Manager THOMAS SCOTT, Foreman, and LIVINGSTONE
RAE RUSSELL, Pattern Maker, all of Callendar Iron Works, Falkirk, in the
County of Stirling, North Britain, 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 :-
The accompanying sheet of drawings is referred to.
In the drawings:
Figure 1 is a side view in elevation and section of a cooking range fire-place
illustrating our invention in its close-fire arrangements:
Figure 2 is a plan through A, A, of the parts shewn in Fig. 1:
Figure 3 is a side view similar to Fig. 1 but shewing the appliances open:
Figure 4 is a plan through B, B, of parts shewn in Fig. 3:
Figure 5 is a view in perspective of the pivotted lever described in this
Specification:
Figure 6 1s a fragmentary diagram shewing a bracket-piece within the
chimney.
Similar letters of reference throughout the diagrams indicate corresponding
parts.
These drawings represent our invention applied to the fire place and flue of a
cooking range made with a cast metal chimney fitted upon the hob. The same
mechanical contrivances, with the exception of d³ Fig. 6, are applicable to a range
having a brick chimney and metal front plate.
Referring to the drawings C represents a flue opening beneath the chimney D,
and E is a pivotted lever for effecting the simultaneous movement of the plate G
which covers over the fire space H and the moveable flue-piece F. The lever E is
pivotted at e' to brackets e: its upper parts have contact with the roof plate of the
portable flue at 1 and its lower parts with the fire-cover at g'. The loose part,,

page_text: of the moveable flue roof is controlled by the bracket-piece d¹ and the flue door ƒ³
is held in position between the toe part of the bracket' and the flue roof at fas
shewn in Fig. 1 the apparatus is adapted for close-fire purposes the smoke and heat
currents proceed upwards from below the hob G as shewn by the arrows.
If the plate G, Fig. 1, is pushed backwards it causes the lever E to rotate upon
its pivots el so that as the lower parts of E are pushed back by G the upper parts
of the said lever press forward the moveable flue F until the parts assume the
positions shewn in Figs. 3 and 4 adapting the apparatus for open-fire purposes: the
direction of the heat current into the chimney being indicated by the arrows in
Fig. 3.
As the moveable flue F is pressed forward the flap f' assumes a horizont il
position resting upon side bearers; its hinder edge being controlled by the
bracket d', and in a similar manner the door plate 3 is forced forward by the
forward movement off until it lies, face downwards, upon the fire cover G. After
the fire cover is pushed back as shewn in Fig. 3, the moveable flue F can be drawn
still further forward over the fire if it is necessary.
In order to reverse the foregoing process and close the apparatus, the moveable
flue-piece F, Fig. 3 must be pushed backwards against the lever E which again
rotates upon its pivots e', forcing back the fire-cover G, resting upon side ledges in
an ordinary manner, until it covers over the fire space again.
As the fine-piece F is pressed backwards the sloping part, fs, bears against the
projection and raises the door plate f³ into the upright position shewn in Fig. 1:
the flap f, by the backward movement of the flue F is forced against the
bracket until frises erect and leaves an open space for the hot currents to pass
through into the chimney as indicated by the arrows in Fig. 1.
We sometimes fix the bracket d upon the back wall, d, of the chimney, as shewn
We make recesses, d', in the
in Fig. 6, instead of the one marked d¹ Figs. 1 to 4.
back wall, d of the chimney, when necessary, for reception of the upper ends of the
lever E.
We are aware that prior to our invention fire places were made having moveable
Alue pieces and travelling fire covers adapting them for open and close fire purposes
alternately; also that various methods existed of simultaneously actuating such
moveable flue pieces and fire-covers in opposite directions; also various methods
for covering and uncovering the back portion of the roof of such moveable flue
pieces: it will therefore be understood that we do not claim any of 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 claim is:-
First. In a fire-place the combination therewith of the moveable flue and fire-
place devices substantially as herein described and drawn or any mere modification
thereof for the purposes specified.
Second. In a fire-place the combination therewith of a pivotted lever E all
substantially as herein described and drawn or any mere modification thereof for
the purposes specified.
