Improvements in Stoves.
I, HERMANN BRIESEMEISTER, of Goltzstrasse 24, Berlin, W. in the Empire of
Germany, Tailor 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 following statement :-
This invention relates to improvements in stoves, in which by the production of
a counter draft before the escape flue the warmth is prevented from escaping into
the chimney.
In the annexed drawing
Fig. 1 shows the stove in vertical section.
Fig. 2 is a plan view and Figs. 3 and 4 are detail views thereof.
The stove consists of the base A and the upper part B. In the base A is the
ash plate a and over the latter is the fire plate b. In the latter is arranged a
circular hole which shows behind a square cut d for the grate c and a hole c¹
beneath the stove door. The plate 6 has further two semi circle like cuts d' for
producing counter draft. On the grate c, fitting exactly thereon, stands the
combustion cylinder e which shows on the front à door hole g and behind a wide
slot f. The enlargement d of the grate cut is provided in order that the slot fis
not obstructed by ash. On the rear side of the stove immediately over the fire
plate b is the escape flue h and between the ash and fire plate is the draft hole i
which allows the air to enter to the fire. In the centre of the draft hole i is kept by
means of cross pieces the counter draft tube 1. The latter reaches up to the
escape flue and ends in a large nozzle. The draft hole i can be closed by a
plate while however the counter draft tube 1 remains opened. The base A is
closed behind by the plate k. The latter has a hole, which receives the combustion
cylinder e and is so large that the smoke can escape between the combustion cylinder
and the plate k.
In the wall of the base under the plate k are two closable slots n through which
air can pass direct to the escape flue .
In the upper part B a little above the combustion cylinder e is arranged a
partition o in which is left a round hole for a cover plate or rings or for the
prolongation of the combustion cylinder.
The action of this stove is as follows:-
But
Through the draft hole i in the base A air enters through the grate to the fire.
The combustion gases escape above between the combustion cylinder and the
plate o and pass towards the lower part of the upper piece B and thence between
the combustion cylinder e and the plate k up to the counter draft tube l.
simultaneously air enters through the holes c d and the slots n before the escape
flue and produces counter draft thus tending to prevent the currents from escaping
to the chimney.
According to the drawing a tube p is also arranged in the combustion cylinder c,
which tube p is fixed on the plate o and serves as a filling hopper but it may
however be omitted at pleasure, in which case the stoking is effected through the
door at g. The stove represented in the drawing may of course receive various
forms according as it is to be used as heating or cooking stove etc.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :--
(1.) An improved heating oven having a tube at the place of escape of the
fire gases from the stove by which tube an air current enters into the stove, to
produce an arresting effect on the fire gases passing downwards over the fire tube e
to cause these gases to remain longer in the stove.
(2.) A form of construction of the stove described in Claim 1 having a filling
tube to be suspended in the combustion cylinder a for the purpose of using the
apparatus as a self feeding stove.
