Heating or warning apparatus
Year: 1888

Specification Accepted, 5th Feb., 1889
I, AUGUST WILLGEROTH of Stadtoldendorf in the Empire of Germany, Engineer,
do hereby declare the nature of my said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Heating or warning apparatus as hitherto used are attended with disagreeable and
health-endangering effects, consisting more especially of smoke and dust,-which
penetrates through the joints and doors of the stoves into the rooms, where the sam
are located and of the waste occasioned by non-use of the greater part of the
combustible gases, by allowing them to escape without being burned. In consequence
of these defects the Inventor has been induced to design or invent a heating
apparatus, which whilst it effects a great saving affords simplicity of construction, not
only prevents smoke and dust from penetrating into the space in or in connection
with which it is placed, but also carries away dust, the smoke of tobacco and cigars,
and other health-endangering vapours or gases, that are created in dwelling-rooms.
The invention is illustrated in the annexed drawings, in which, Figure 1 shows an
outer view of the stove, and
Figure 2, a longitudinal section through the same.
Figure 3 is a section through the lower part of the stove at the line X X Figure 2.
Figure 4 is a horizontal section through the stove at t, u, Figure 2.
Figure 5, is a cross section at w. x. Figure 2.
Figure 6 shews a cross section through Figure 2 at the line y, :, and
Figure 7, a cross section at the line u, v. figure 2.
The apparatus comprises a tightly closed ash-pit A, which at the same time serves
to heat the air used in the furnace to support combustion of the fuel, and seldom
requires to be cleared out during the cold season. This clearing out is effected
through the door n. a is the fire place, having a hanging grate (the real hearth of
the fire). To the lower part of the hopper h is provided the bridge c which causes the
gases produced to be more readily burned. The waste gases pass up and through
the smoke pipe d' pipes i, d² ², d³, i³ d', i, d' and thence to the outlet see
Figures 2, 5 and 6. Above the centre of the fire place a there is arranged the coal
hopper h, which receives sufficient coals to last a considerable time, and delivers them

page_text: as required to the firing place a. The combustible matter can pass away only through
the fire, and in passing the point c is ignited.
The fire place a is kept filled by the coal in the hopper k.
The grate is constructed of fire bars resting on a back bearer and their front ends
on a rod p which supports them, by moving the rod p the fire bars are agitated and
the fuel falls from the hopper h onto the fire, the movement of the rod is limited by
the stop p p. The grate can be drawn to one side by the rod pas shown in dotted
lines so that the lower part of the fire place is sufficiently uncovered as to allow
objects that will not burn such as stones etcetra to fall into the ashpit A without the
necessity of opening the stove.
The ventilation pipe e is fixed in the heating pipe d³, so as to heat the air used in
the fire to a high degree and it can be, regulated by the valve e¹ by means of the
screw by which means. while it is open, air that has been made moist or damp by
the water in the bucket e is admitted to the grate, and so burns the gases more
effectually, the air entering partly through the opening e', but in the main part
through the opening in the hermetically closed preparatory heater.
The state of the fire is observed through the cover or door..
The cleaning of the smoke conduit is effected through the covers which are seated
in sand, in order to produce a hermetical closing.
For the reception of soot and its removal, I use the funnels m, and the removal
or cleaning can be effected during the firing, as the soot need not be drawn or
passed over the grate.
The whole arrangement is particularly characterized by the fact that the Invention
does without the principal parts of the heating arrangements known hitherto, namely
those above the grate, using instead of such, a fire place with a peculiar burner, and
a coal hopper in a tightly closed ashpit, with soot-collectors, and which serves also
as a preparatory heater of the air to support combustion of the fuel.
The objectionable interruption above the grate is thus removed, because by this
Invention a hermetically closed smoke conduit is. created from the head of the
chimney down to the entrance of the air e of the ventilation pipe, making any
escape of the smoke into the locality to be heated impossible.
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 hanging grate arranged in connection with the fire-place in such a manner
that air can have access to the fire, and adapted to be drawn sideways by means of the
lever rod p sufficiently to allow materials that will not burn, such as stones, etc., to fall
into the hermetically closed ash pit A, substantially as set forth.
2. In a stove with the arrangement characterized under claim 1, the application of
the ventilation pipe e in the heating pipe d³, in combination with the valve e¹ and the s
openings e and e³, said valve being arranged to operate in such a manner that a small
portion of the air passed through the pipe e can enter through the opening e of the
coal hopper, and the greater part through the opening e; substantially as set forth.
3. The combination of the flues d', d², d³, d, d, with the funnels m by which the
soot from said flues is collected in the ash pit A; substantially as and for the purposes
set forth.
