RESEDI
WO GEORGE GORDON BRODIE of Catherine Street Aston Birmingham, Ironfoundor
and JAMES DAMREL PRIOR of 143 Isledon Road Finsbury Park London Manager
do hereby declare the nature of this invention to be as follows:-
The arrangement of the two side doors and top flap which when closed form
the front of the flue for the closed fire and when open form the Hood for the
open fire in such a manner that the Hood can be opened or closed by one motion.
The two side doors are pivotted vertically and when closed either meet in the middle
or overlap each other and when open stand at right angles with the back of the Range.
Their top edges slope downwards from the top pivot at about an angle of 45 degrees.
The flap is hinged horizontally to the front plate of the hood at about the same level
as the top pivots of the side doors and when closed hangs down vertically on the front
surfaces of the side doors-When open and the side doors are also in their open position
the under side of the flap rests on the sloping top edges of the side doors thus forming
the roof of the Hood.
The right hand side door is provided at its back with a projection at right angles
to it which in its closed position stands back in the flue.
The left hand door is provided with a small projection or ear at its back.
From the extremity of the projection on the right hand door to the ear on the left
band door extends a connecting rod which is loosely jointed to the said projection and
ear respectively.
The front surface of one of the doors has a handle or ear with a suitable
hole into which a hook can be inserted for pulling it open. By pulling this
door open the connecting rod communicating with the other door pulls that door
open also.
The two doors in opening also open the top flap-To shut them all it is only
necessary to push in one of the doors and the other door and the flap will
close also.

Improvements in Convertible Open and Close Fire Hoods for Kitchen
Ranges.
We GEORGE GORDON BRODIE of Catherine Street Aston Birmingham Ironfounder
and JAMES DAMREL PRIOR of 143 Isledon Road, Finsbury Park, London, Manager
do hereby declare the nature of our 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 consists of the improvements in convertible open and close fire
hoods for kitchen ranges hereinafter described and illustrated in the accompanying
Drawings.
Our said invention consists of the arrangement of the two side doors and top flap
which side doors and top flap when closed form the front of the flue for the closed fire
and when open form the hood for the open fire in such a manner that the hood can be
opened or closed by one motion. The two side doors are pivotted vertically and when
closed either meet in the middle or overlap each other and when open stand at right
angles with the back of the runge. Their top edges slope downwards from the top.
pivot at about an angle of forty five degrees. The flap is hinged horizontally to the
front plate of the hood at about the same level as the top pivots of the side doors and
when closed hangs down vertically on the front surfaces of the side doors. When
open and the side doors are also in their open position the underside of the flap rests
on the sloping top edges of the side doors thus forming the roof of the hood.
The right hand side door is provided at its back with a projection at right angles to
it which in its closed position stands back in the flue. The left hand door is provided
with a small projection or ear at its back. From the extremity of the projection on
the right hand door to the ear on the left hand door extends a connecting rod which is
loosely jointed to the said projection and ear respectively.
The front surface of one of the doors has a handle or eye with a suitable hole into
which a book can be inserted for pulling it open. By pulling this door open the
connecting rod communicating with the other door pulls that door open also. The two
doors in opening also open the top flap. To shut them all it is only necessary to push
in one of the doors and the other door and the flap will close also.
Figure 1 represents in front elevation and Figure 2 in side elevation the flue of a
kitchen range provided with a hood constructed according to our invention, the said
hood being folded or closed as used with a close fire; Figure 3 represents a side
elevation of the hood opened as used with an open fire; Figure 4 represents a plan of
the closed hood and Figure 5 a plan of the open hood.
The same letters of reference indicate the same parts in the several Figures of the
Drawings.
a is the flue of the kitchen range to the front of which flue are pivotted the two
side doors b and c and the top flap d. The two side doors b, c turn upon the vertical
pivots ee at top and bottom and the top flap d turns upon the horizontal pivots f, f
working in the side bearings 9, g on the flue. When the side doors b, c are closed they

page_text: overlap one another as best seen in the plan Figure 4. The top edges of the side
doors are inclined downwards from the top pivots at about an angle of forty five
degrees as seen in Figure 3. When the side doors b, c are closed as represented in
Figures 1, 2 and 4, the top flap d hangs vertically in front of the closed side doors b, o
inside the flue a and when the side doors b, c are opened in the manner herein after
described, the top flap d is also opened and is supported on the inclined tops of the
open side doors and constitutes the roof or top of the open hood. The two side
doors b, c are so coupled together that the opening or closing of one door effects the
opening or closing of the other door.
The doors b, c are coupled together in the following manner. On the inner side
of the door bis a projection or arm h at right angles to it and on the inner side of the
other door c is a similar projection or arm the said projections or arms being coupled
ogether by a link or connecting rod k loosely jointed to the said projections or arms h
and i as best seen in Figure 4.
l
On the front face of the door b is a handle or eye linto which a hook can be inserted
for pulling it open or closing it. When the hood is required to be used with the open
fire of the kitchen range the handle or eye on the door is pulled outwards by the
hook before referred to. On opening the door & the link or connecting rod k coupling
the two doors together pulls open the other door c. In the act of opening the two
doors, the inclined edge of the door braises the top flap d which top flap when both
doors b, c have been opened is supported by them in the manner represented in Figures 3
and 5. In order to shut the hood the door bis pushed inwards. The pushing inwards
of the door b effects the closing of the door c, the door c closing in advanco of the
door b and the flap d being unsupported falls into the vertical position represented in
Figures 1. 2 and 4. The closing of both the side doors may be effected by closing the
door c but it is most conveniently effected by acting on the door b.
Thus, the hood at the front of the flue for an open fire can be brought into
use by one motion and the front of the flue closed by one motion when a close fire is
to be used.
The outward motion of the doors b, c may be limited so as to prevent them
opening beyond a right angle by a stop on the hot plate of the kitchen range
or by a knuckle near the pivot edge of one of the doors bearing against the front edge
of the flue a.
Having now particularly described and ascertained the nature of our invention
and the manner in which the same is to be performed we declare that we claim
as our invention of "Improvements in convertible open and close fire hoods for
kitchen ranges."
