Improvements in and relating to Heating Stoves.
I, OSCAR SCHWIGGE, of 138 Müllerstrasse, Berlin, Germany, Engineer, 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 and relating to heating stoves and
my invention consists in the improved construction of heating stoves (such for
example as tiled stoves) as will be hereinafter described whereby greater economy
in the consumption of fuel will be attained.
In order that my invention may be readily understood reference is made to the
accompanying drawings wherein like letters of reference indicate corresponding
parts throughout the several figures and in which :-
Figure 1, represents a sectional front elevation of my invention.
Figure 2, represents a sectional side elevation of my invention, and
Figure 3, represents a sectional plan view thereof.
In carrying out my invention I construct a tiled stove having the usual crowning
and having a grate or fire place A. Said grate is partially surrounded with double
walls and is provided with an opening Chaving a suitable cover, through which
opening fuel and rubbish may be introduced into the grate A. The stove is also
provided with openings d and e the former opening being provided for the purpose
cf enabling the fire to be readily kindled, and also for the purpose of permitting
the ashes and other refuse being readily removed, and the opening e being provided
for the purpose of permitting a sufficient quantity of atmospheric air being
supplied to the fire, said air being compelled to travel through channels as will be
bereinafter described, said opening e being also provided with an adjustable cover
by means of which the supply of air to the fire may be regulated in quantity, or
if desired, entirely cut off. The air which is admitted at the opening e travels
through a channel h in which channel said air is heated, passing out at the opening i
under the fire bars g. I also provide a vessel k containing water, which water
becomes heated on account of its close proximity to the fire, so that the portion of
the air which passes through the movable grating f to the fire, becomes damped by
being mixed with the steam from the vessel k so that carbonic oxide and hydrogen
gas are formed. The smoke and other products of combustion are drawn through
openings into a channel m in which they are mixed with air which is also
admitted through the opening e and which air is warmed by passing through a
channel n, the whole mixture passing at the opening o into the flame channel p in
which the whole gases and other products of combustion are burnt in a smokeless
and odourless flame. The resultant hot gases next pass through winding channel r¹
and through the pipe 9 to the chimney. In order that the atmosphere in the room
in which my improved stove is situated may be more readily warmed, I provide
the lower part of the stove with an opening covered by a grating r said opening
communicating with a channel 6 leading to about the top of the stove, its upper
exit being covered by a grating s, the arrangement being such that while the
stove is warm a constant circulation of the air in the room goes on, the colder air
entering through the grating and after becoming heated passing back into the
room through the grating s. This circulation of the air within the stove continues
until the temperature of the air within the room is equal to the temperature of the

page_text: air within the channel b. For the purpose of warning the air which is admitted
into the room-through the aperture a in the wall-for the purpose of ventilation,
I connect said aperture a with the channel so that the cold air passing through
the aperture a from without the room is warmed in the channel b before being
admitted into the room. The channel connecting the aperture a with the channel b
is preferably provided with a damper or equivalent t so that the quantity of cold
air admitted may be regulated or, if desired, completely cut off.
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:
1. A heating stove having a fire place A partially enclosed by double walls and
provided with openings c d and e, the opening e being for the purpose of admitting
air, said opening being provided with means whereby the quantity of air admitted
may be regulated, chanuels and n, a removable grating f, a vessel k adapted to
contain water, fire bars g, apertures 1, channels m p, r¹ and b, all for the purposes
and substantially as described and illustrated.
2. In a heating stove constructed substantially as described, channels a and b
for the purposes and substantially as described and illustrated.
3. In a heating stove the general arrangement of parts, substantially as and for
the purposes described and illustrated.
Dated this 16th day of September 1895.
