I, HEINRICH DEMPEWULF of Willebadessen in the province of Westphalia,
Kingdom of Prussia and Empire of Germany, Inventor do hereby declare the
nature of this invention to be as follows:-
The improvements forming the subject of this application for Letters Patent
consist essentially in causing the products of combustion, which have hitherto
been allowed to escape freely from the surface of the piled up fuel, to pass .through
the lower layers of the fire, which are at an intense heat, and thus securing complete
combustion of the smoke.
In the application of the invention to an ordinary chamber stove, a funnel
shaped receiver is let into the casing of the stove, the open end of which reaches
down nearly to the grate. This cover is closed at the top and is connected at one
side with the stoke hole. The poking hole and the door of the ash box are her-
metically closed so that the air requisite for combustion must pass in through the
stoke hole. By the current thus induced all the combustion products will be
forced to pass through the layers of fuel resting on the grate which are in active
combustion, and are thereby exposed to as complete a combustion as possible.
The receiver may be constructed, either with a simple smooth edge and slits or
with a crenelated edge.
The invention is applicable to various patterns of fire places and the receiver
may be constructed of any suitable shape or material, provided its "lower edge
come sufficiently close to the grate, so that the products of combustion may pass off
in the manner above described.

⚫I, HEINRICH DEMPEWULF of Willebadessen in the Province of Westphalia
Kingdom of Prussia and Empire of Germany, Inventor, 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 following statement :-
The improvements forming the subject of this application for Letters Patent
consist essentially in causing the products of combustion which have hitherto
been allowed-to escape freely from the surface of the piled up fuel to pass through
the lower layers of the fire which are at an intense beat and thus securing complete
combustion of the smoke.
Referring to the accompanying drawing which shows the application of the
invention to an ordinary chamber stove. A funnel shaped receiver b is let into
the casing ȧ of the stove, the open end of which reaches down nearly to the
grate r. This cover is closed at the top and is connected at one side with the
stoke hole c. The poking hole d, and the door of the ash box e are hermetically
closed, so that the air requisite for.combustion must pass on through the stoke
hole c. By the current thus induced all the combustion products will be forced to
pass through the layers of fuel resting on the grate which are in active combustion,
and are thereby exposed to as complete a combustion as possible. The holder b
may be constructed either with a simple smooth edge and slits as shown in
Figure 1, or with a crenelated edge as shown in Figure 3.
The invention is applicable to various patterns of fire-places, and the part b may
be constructed of any suitable shape or material, provided its lower edge come
sufficiently close to the grate so that the products of combustion may pass off in
the mannor above described.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In fire-places the directing of the draught in such a manner. that the products
of combustion are passed from the upper layers. of fuel, through the lower more
intensely ignited layers for the purpose of securing a smokeless combustion.
2. The combination of parts consisting of a funnel shaped holder b connected at
top with the charging opening c of the fire-place, and reaching down almost to the
fire bars provided either with openings, crenelations, or pieces cut out all round its
lower edge, for the purpose of directing the combustion products in the manner set
forth in claim No. 1.
