Improvements in Stoves for Lignite Cakes, Peat, and the like Fuel.
We, CLEMENS LINZEN, Jun., in the City of Unna, Westphalia, Manufacturer,
EWALD DEMMER, in the City of Barmen, Bismarckstr. 69, Chimney Sweeper,
EDUARD DISSELKAMP and ERNST DISSELKAMP, same place,. Berlinerstrasse 87,
Merchants, and RUDOLF DISSELKAMP, same place, Mühlenweg 2, Merchant, 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 follow-
ing statement:-
i
The nature of the said invention and improvements herein contained and set
forth consists of an arrangement of the fire chamber within an outer casing and
forming in its upper portion a conically shaped fuel chamber in the manner and
by the means substantially as herein described and set forth. It also consists
in the employement of a sort of blast pipe being applied to the top of the fuel
chamber communicating therewith and with the air above the stove or heater in
the manner and for the purposes substantially as herein described and set forth.
It also consists in the arrangement and employment of a chamber arranged for
the admission of air which is arranged in front of the stove or heater in the
manner as herein described and set forth.
Like letters of reference represent and refer to like or corresponding parts
of the said invention and improvements.
Figure 1 represents a vertical section of a lignite cakes burning or heating
stove on a vertical line through the centre of the exit pipe;
Figure 2 is a vertical section taken at right angle;
Figure 3 is a horizontal section along line A-B of Figure 1;
Figure 4 is a horizontal section along line CD of Figure 1.
a is the base of the stove or heater of any suitable or desired form which
contains the ash pit and is closed at its top by a suitable plate c. From said
plate projects a circular or otherwise shaped flange which is for the purpose of
receiving the lower end of the outer casing d the form of which may
be either circular or otherwise suitably shaped Within this outer
casing is seated upon the base and secured thereto in a similar manner, as the
casing da cylinder e forming, the combustion or fire chamber. Upon it is seated
and secured in a suitable manner a hollow cone which forms the
fuel chamber. By means of the outer cylinder 7, the inner cylinder e and
the cone is formed between the two a chamber E which is closed at the top by a
plate g but has connection with the ash pit b by slots or apertures / cut in the
plate c. The plate a projects within the top portion of the cone f being thus a
support for an annular plate which diminishing the opening of the conc is
provided with a collar 2. By means of this collar a blast pipe k is held in position
which is fastened to the cover of the stove the upper opening of the blast pipe
is covered by a lid but so that air may enter the blast pipe and can be admissed
to the fuel and the fire chamber e. The latter communicates with the chamber E
by means of an aperture n and has arranged in front of the door oa vertical
grate p. Over this grate is arranged in front of the stove an air admission
7.

consists of a fixed portion & and a movable portion ", which either may be placed
over or under the fixed grate. When the stove is burning the grate is closed so
that no fuel or ashes can be passed into the ash pit b. ut is a horizontal partition

smoke and gas exit pipe w the door for removing the ash from the ashpit.
v is the
The operation of our stove is as follows: The stove is charged with fuel after
opening the cover and removing the ring i by filling the fuel chamber f. The
stove is closed and the fuel ignited through the door o and the vertical grate p.
Air is admissed through the channel q. When the fuel has thoroughly ignited
the gases and smoke evolved pass through the aperture n into the chamber E
descend this chamber pass round the plate and enter the exit pipe v. On its
way they heat the fuel chamber f containing a stock of fuel drying thus the fuel
and causing thus the separation of the bituminous gases and moisture. The
latter is kept downwards by the air coming from below the stove through the
blast pipe and also dried whilst the gases are pressed by the said air by and by
into the flames so that they are perfectly burned and prevented from entering
into the room. The fuel being contained uppermost in the chamber f will be
prevented from being ignited it can be kindled when coming into the fire
chamber e and thus an economical burning of the stove will be obtained in as
much as the admission of air can be perfectly and securely regulated.
The grate which is normally closed allows a perfect burning up of the fuel, by
moving the grate the ashes will be pulverized before coming in the ash pit.
Gases evolving therein from kindling ashes can enter through the slots h the
chamber E and join the gases therein contained. The admission of air from above
the stove improves the air in the room.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1) The base a constructed to receive the outer casing 6 having seated upon it
a cone f which together with the casing forms a flue space or chamber E said
chamber communicating with the ashpit through slots hand with the fire chamber
with an aperture n said chamber having arranged therein an air admission
channel opening in the upper part of the stove and ending before a vertical
grate disposed in front of the fire chamber and forming part of the same as
illustrated and for the purpose set forth.
"
2) The base a combined with the outer casing & and containing the fire
chambere having seated upon the cone f forming the flue E with the gas
directing plate u, communicating with the base through slots and with the
fire chamber through an aperture n and having arranged in it the air admission
channel 9 said cone having arranged on its top a blast pipe fixed to the cover l
and communicating with the air above the stove for the purpose as illustrated
and set forth.
