COMPLETE SPECIFICATION.
Improvements in or appertaining to Fire Places.
I, MORITZ LANDMANN, of 16, Reuschstrasse, Breslau, in the Empire of
Germany, Soap Boiler, 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:-
The subject of the present application for Letters Patent consists of a fireplace
in which the fuel is completely consumed and utilised to the fullest extent leaving
only a small quantity of ash behind.
The invention is illustrated in the accompanying drawing in which
Figure 1 shows the general arrangement with perforated fire basket.
Figure 2 shows the same with a filling hopper of different shape and a fire
basket provided with slits.
Figure 3 shows the shape preferred for heating, boiler, or evaporating furnaces
in which the fire basket possesses alternately perforations, holes or slits, and
Figure 4 shows the shape for iron stoves.
The mechanism consists as shown in Figure 1 of a fire basket C which may be
of cylindrical, oval, angular or other desired form and which is supported by
means of a ring D cast thereon in the cover A fitting air-tight upon the ring B
fixed inside the said cover.
The lower horizontal part of the fire basket is provided with slits in the same
manner as the usual grates and the middle vertical part is provided with holes,
slits or both and has underneath at the side an opening E serving for the removal
of the ashes and clinkers. The upper part may form one piece with the fire
basket C or it may be separate and simply placed upon it; the same can be
prolonged in the same width or be narrowed or widened and be with or without
holes or slits. Underneath the fire basket C is placed the ash-pit G.
kindling can be arranged from above or below and is preferably from below when
a quick fire is to be obtained and from above when a slow fire is desired whereby also
at the same time a fire most free from smuke is obtained, in the same manner the
supply of fuel can be arranged from above or below.
The
The apparatus can also be placed in almost any existing fire-place without
serious difficulties and outlay. For boiler furnaces, kitchen fires, boiling or
henting furnaces the usual grate K can, as shown by way of example (Figure 3)
be placed correspondingly lower. The fire basket C can be set upon it and he
made tight about at the level of the old grate. In the case of iron stores
(Figure 4) the fire basket C is simply placed upon the old grate K and is made
tight in the same manner above; in all these cases it is however more
advantageous to dispense with the cast ring D and instead of the same as shown
in Figure 4 to use the ring D independently constructed which may be made
either Hat as in Figure 4 or sloping (Fig. 3) of iron, fire-clay or other suitable
refractory material and made to fit air-tight to the fire basket C. In all cases the
previous fire door and ash-pit door can be utilised again in the same way, the
lower part K of the fire basket can be dispensed with because the old grate will
replace the same. A very important advantage in large works consists in that the
firing need suffer scarcely any interruption because the fire-bux door need only be
opened for the supply of fuel, the removal of ashes and clinkers takes place from
below. For the purpose of more easily filling the stove there is placed at the
upper end of the fire basket C a hopper capable of containing a quantity of fuel

page_text: exceeding the immediate requirement so that the same through the heat arising is
previously warmed. The section of this hopper may be of any suitable shape.
The object and intention of the invention is that the air is compelled to pass
over the burning material below the closing ring D in greater quantity in
consequence of the considerable surfaces presented by the same and so in
consequence of the increased supply of oxygen secures a more rational utilisation
of the fuel and effects a more intense and almost smokeless combustion.
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 :-
A fire-place in which the draught is obliged to come in contact with a large
surface of the fuel characterised by the use of a fire basket C provided with holes,
slits or both together with a flat grate K and hermetically fitting ring D for the
purpose of utilising the fuel to the best effect and of obtaining as smokeless a
combustion as possible.
Dated this 2nd day of March 1896.
