Improvements in or relating to Stoves or Fireplaces.
A communication from A. ERICHSEN, of Nyborg, in the Kingdom of Denmark,
Ironmonger.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to stoves for heating purposes and the like.
The stove consists of two parts, an inner and an outer one. The inner part
serves to receive the wood or fuel and forms a combustion chamber, while the
outer one is a chamber of the circulation of hot air.
The inner chamber consists of a foot piece having a grate basket and a movable
grate which by means of a hook may be shaken or vibrated from without. In
the foot piece there is also placed the ash box to this is attached a front piece
and door and the air inlet or damper.
In a fold of the foot piece is placed the so named 'pig' which on one side is
provided with a grate. To the pig is screwed a case having a cleaning floor and
mouth pieces, which may be closed by doors. One of these doors is provided
with an air inlet.
In the pig there is placed a reed' of cast iron which is fastened to it with
screws; this reed has partly around its upper circumference a collar, so that it
in this place lies close to the inner wall of the pig while there is an opening
before the mouthpiece so that a channel is formed here between the outer side of
the reed and the inner side of the pig. The reed is closed above by a cover
which may be turned around an axle projecting through the stove, so that the
cover may be opened and closed from without.
The pig and the case are closed by a cover in which is formed a hole. Above
the cover is placed a case in which is formed a cleaning hole, closed by a lid
or cover. Above this case is placed a cylinder having a tube for the smoke
and closed by a cover in the form of or provided with a hollow vessel or shell
so that it serves for the evaporation of water.
The outer stove consists of a foot piece provided with feet a cloak or casing
and perforated cylinders of cast-iron which are provided with doors.
When the stove is to be used, the door and its air inlet and the cover of the
reed are closed while the doors and the air inlet of the inner chamber are opened.
The wood and fuel are placed on the grate and lighted then coals are gradually
filled on through the door until the coals are burning to the required height in
the stove. Now the doors and the air inlet are closed, while the other door and
the cover are opened and the reed is filled with coals, after which this latter floor
and the cover are again closed, while the air inlet is opened sufficiently for
regulating the conveyance of air to the wood and coals. The air passes through
this air inlet and the channel down to the fuel in the pig and from here through
.

chimney.
At the same time air is sucked either through channels on the side of the
casing for through holes in its foot plate and a perforated ring up into the
chamber between the inner and the outer stove and passes out through the openings
in the perforated cylinders at the upper part of the stove.

Improvements in or relating to Stoves or Fireplaces.
A communication from A. ERICHSEN, of Nyborg, in the Kingdom of Denmark,
Ironmonger.
I, ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:--
This invention relates to stoves for heating purposes. The stove consists of
two parts, an inner and an outer one. The inner parts serves to receive the
wood or fuel and forms a combustion chamber, while the outer one is a chamber
of the circulation of hot air.
In the accompanying drawings,
Fig. 1 is a diagrammatic view of the stove while
Figs. 2, 3 and 4 are detail views.
The inner chamber consists of a base a having a grate-basket b (Fig. 2) and a
movable grate which by means of a hook or handle (Fig. 3) may be shaken
or vibrated from without. In the base there is also placed the ash box d; to
this is attached a front part e with door f and air inlet or damper g.
Above the base is placed the so called 'pig' A which on one side is provided
with a grater. To the pig is secured a casing G having a cleaning door y and
openings h and i, which may be closed by doors j and k. The door k is pro-
vided with an air inlet l.
In the pig there is placed a fuel receptacle 13 say of cast iron, which is fastened
to it by screws m¹ and n'. This receptacle has partly around its upper circum-
ference a collar o, so that it at this point lies close to the inner wall of the pig,
while there is an opening before the opening i so that a channel Z is formed here
between the outer side of the receptacle B and the inner side of the pig. The
receptacle B is closed above by a cover which may be opened or moved by a
rod projecting through the stove, so that the cover may be opened and closed
from without. The inclined dotted lines Fig. 1 show the cover opened.
The pig A and the casing G are closed by a cover m, in which is formed
a hole. Above the cover is placed a case in which is formed a
cleaning-hole ?, closed by a lid or cover q Above this case O is placed a
cylinder having a tube s for the smoke and closed by, a cover t; in the, form
of or provided with a hollow vessel, or shell so that it serves for the evaporation
of water.
The outer stove consists of a base C provided with feet D a casing E and
perforated cylinders F of cast-iron which are provided with doors.

page_text: When the stove is to be used, the door k and its air-inlet and the cover u
are closed, while the doors f and j and the air-inlet g are opened. The wood
and fuel are placed on the grate e and lighted, then coals are gradually filled on
through the door j, until the coals are burning to the required height in the, stove,
shown by the line N-N Fig. 1. Now the doors f and j and the air-inlet g are
closed, while the door k and the cover u are opened and the receptacle B is filled
with coals, after which the door k and the cover u are again closed, while the
air-inlet is opened sufficiently for regulating the supply, of air to the wood
and coals. The air passes through the air-inlet and the channel % down to the
fuel in the pig A and from here through the grater, the casing G, the hole n,
the case O and the cylinder r to the tube s and through this into the chimney.
At the same time air is drawn in either through channels on the side of the
casing E or through holes 1, 2, 3 (Fig. 4) in the base H and through a perforated
ring 4 Fig. 1 up to the chamber between the inner and the outer stove and
passes out through the openings in the perforated cylinders F at the upper part of
the stove.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed, I declare that what I claim is:-
1. A stove with an air-ventilation, comprising a base with door and air-hole,
a grate basket placed therein with movable grate and a pig placed above the base
with a coal receptacle 13 and a grate e, a casing G with air-hole 7, through which
the air that is needed for combustion passes along a channel Z between the pig
and the coal receptacle and through the grate and the casing G to the upper
part of the stove, to the smoke tube S, substantially as described.
2. The combination and arrangement of parts constituting the complete stove,
substantially as described and illustrated in the accompanying drawings.
Dated this 1st day of September 1897.
