1 WILLIAM JOHN BERRY Sui veyor 5 Harbut Road, St. John's Hill New
Wandsworth London S. W. do hereby declare the nature of this invention to be as
follows:-
My invention relates to a hot an or smoke chamber, and to a combination of
this and other special features which I hereinafter describe, the combined use of
which secures, for the portable self-setting range advantages that are more efficient -
than have hitherto been adopted.
The range can be used as A close range for baking. A slow combustion range
for economising fuel when not cooking. An open fire range with drop bar when
cheerfulness and heat are required in the 100m. And it will also assist in preventing
a down draught in the chimney.
In constructing the range 1 fix a chamber of extin large size on the top plate
immediately at the back of the fireplace, into which the whole of the smoke passes.
This chamber is therefore always full of hot air which, when the chamber is closed
tends to resist a down draught; consequently what is known as a smoky chimney
may be cured by the use of this improvement.
The front of this chamber is fitted with folding doors and a flap which opens and
forms a hood over the fireplace so that by removing a section of the top plate the
range can be used with an open fire for drying purposes.
The fireplace is of such a depth that a portion of it is under the hot air chamber;
this affords by the adjustment of a damper, a means by which the smoke from the
fireplace can be taken direct into the flue, without first going around the oven.
This feature when used in conjunction with the hinged door and blower, which are
designed to close the entire front of the fireplace, renders the lange practically a
slow combustion one.
The frout of the fireplace is fitted with vertical bars for a portion of its height.
These bars are in one casting with the bottom, the whole inovable. Above the
vertical bars in place of the ordinary fixed bar or plate, there is a set of horizontal
drop bars which turn on centres.
The top plate is made in sections with rings of convenient size, the section
Immediately over the fire being somewhat wider than the fire itself; and when
removed allows of a large utensil being placed directly over the fuel.
Dated this 19th day of October 1895.

I WILLIAM JOHN BERRY Survey or 5 Hat but Road, St. John's Hill New
Wandsworth London S W. do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascei-
tained in and by the following statement:-
My invention relates to improvements in portable self setting cooking ranges,
more especially to a hot air oi smoke chamber, and to a combination of this and
other special features hereafter described, the combined use of which secures
advantages which are more efficient than have hitherto been obtained, whereby it
can be used, viz
(1) As a close range for baking,
(2) As a slow combustion range for economising fuel when only a small fire 13
1equired,
(3) As an open fic range with diop bar, when cheerfulness and heat are requied
in the room.
This range is thus particularly suitable for artizans' and other dwellings where
the one fire in the living room has to meet all requirements.
The following is a full and detailed description, reference being mado to the
drawings filed herewith.
Figures 1 & 2, 1cpiesent a large smoke or hot an chamber, Fig 1. shows the
front elevation of the chamber when closed, and Fig. 2 a perspective sketch of
the chamber when open as applied to the range.
Fig. 3. represents a portion of the front of the range indicating the other special
features.
Fig. 4. is a cross section showing the combination of the whole of the features.
The same letters indicate the same parts in each figure.
((a) Fig. 1. 2 & 4) is a chamber fixed on the top plate of the range, into which
the whole of the smoke has to pass, the chamber therefore when in uso (and
particularly when closed as shown in Fig. 1.) is full of hot air, the whole of which
passes through a small outlet ((b). Fig. 1. 2 & 4) on the top into the chimney and
thereby causing a strong current of hot air which will resist a down draught and
cure what is known as a smoky chimney. This chamber will in all cases be
one foot in height, (from the top of the range to the bottom of the small outlet on
the top of the chamber forming the connection between the chamber and the flue,)
SIX inches in depth, and in width equal to the space occupied by the section of top
plate immediately over the fine, the size of the last dunension being governed by
the size of the range. The front of the chamber is fitted with folding doors and a
flap which opens and forms a hood over the fireplace (Fig. 2.) so that by removing
a section of the top plate the range can be used as an open fire range.
The fireplace is constructed in such a manner that a portion of it extends under
the hot air chamber, and affords by the adjustment of a damper ((e) Fig. 4,) a
means by which the smoke from the fireplace can be taken diect into the chamber
without first passing around the oven.
The front of the fireplace is fitted with vertical bars foi a portion of its height,
these bars are in one casting with the bottom, the whole movable ((d) Fig. 3 & 4,).
Above the vertical bais in place of the ordinary fixed bar or plate is provided a
set of horizontal drop bars which turn ou centres ((e) Fig. 2, 3 & 4). These drop
bais will be from four to five inches in height and in width equal to the space
occupied by the section of top plate immediately over the fire A hinged door (()
Fig. 3 & 4) and a specially designed blower ((g) Fig. 3 & 4) which has a cuived
flange at the botton that fits into the rim of the ash tray ((h) Fig. 3 & 4) nie

page_text: provided for the purpose of entirely closing the front of these bars and by so doing
making the range practically a slow combustion one.
The top plate of the range is made in sections with rings of convenient size, the
opening to be filled by the section immediately over the fire indicated in Fig. 2
& 3 by the letter (1) is from two to three inches wider than the fire itself, thus
allowing of a large utensil being placed directly over the fuel.
My improvements can be applied to portable self setting cooking ranges of any
size, which can be provided with boilers or without.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
(1.) A large hot an or smoke chamber fixed at the back of the fireplace of the
range, as described and for the purposes specified.
(2.) A combination of the before mentioned large hot air or smoke chamber with
a drop bar in the front of the fireplace, combined movable front & bottom bars to
the fireplace, which fireplace can be entirely closed by the hinged door and blower
of the shape delineated, and the extra wide section of hot plate over an essentially
small fireplace, the whole combined as herein before described and illustrated in
the accompanying diawings, for the purpose of efficiency and economy in the
portable self-setting cooking range.
