Improvements in Stoves.
We, RUDOLF KESZLER, No. 37. Muranyi-Gasse, Budapest VII., Butcher, and
JULIUS KESZLER, Clerk, of 11, Tompa-Gasse, Budapesth, Hungary, do hereby
declare the nature of our invention and in. what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
The present invention relates to stoves and consists of the details of construction
herein after set forth.
In order to render the present specification more easily intelligible reference
is had to the accompanying drawings in which similar letters of reference denote
similar parts throughout the several views:

The stove consists of the fire box having grate m¹ fire door opening
pit s with ash pan o, bottom plate z with downwardly extending supporting rim
or feet and a casing t, which extends upwardly from the plate z to the point or
plane at which the cylindrical upper part of the stove joins the slightly down-
wardly tapered fire box. The bottom plate z is provided with openings PP
for the admission of cold air, and the casing or jacket is provided with
openings at the upper end, which allow the warmed air to escape. These
openings may be closed or partially closed by means of a ring k, which has
corresponding openings and which when turned will close the openings of the
jacket. At the top of the fire box and some little distance above the same an
oven his provided, a protecting plate i being mounted within the said fire box
below the oven to protect the bottom of the same from the immediate action
of the flames. The oven is provided with a fire door opening h. From the top
of the oven a tube f extents vertically upwards and is provided at the top with
a hinged cover f', the lower part of the tube is provided with outlet openings g,
which extend through the outer shell 6 and may be provided with cocks. The
tube itself is provided with a spiral flange b, which extends up to approximately
the top of the tube and which is covered by a cylindrical shell a formed of a
series of sections a a a a, placed one on the top of the other & on the interior
of which the spiral flanges may be cast. The smoke and gases of combustion
pass out of the stove at d, which is provided with a slide, said slide being
designated by e and constructed so as only to vary the opening at d. without
at any time entirely closing it, so that no danger can exist of the injurious
gases of combustion being prevented from escaping entirely. A hand hole c
for cleaning the spiral passage is provided at about the centre of the shell a.
If desired a mantle or casing a¹ (Fig. 2) may be provided around the shell a
and may be water-tightly closed on to the shell a at the top and bottom and
provided with water inlets and also outlet cocks at the lower end. Both the
tube f and the space between the shell and mantle may be employed as boilers,

page_text: and in the case of the former the cover f¹ may be weighted so as to act as a
safety valve or the tube and mantle may both be provided with safety devices
of any of the known constructions. In Fig. 2 the tube f is shown provided with
two outlet cocks as indicated at g g'. The boiler space between the mantle and
shell may be provided with a simple steam outlet leading into the spiral passage
between the shell and tube f.
The construction of the fire door is shown at Figure 4. The fire door opening
is provided with a frame E having lugs C C₁ to support a bar or rod B and the
fire door consists of two parts A A¹ having upper lugs D D₁ by which the said
doors are suspended on the bar B. The fire door is opened by pushing the two
doors apart as will be evident from the drawing.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
1: Improvements in stoves which consist in the arrangement of a mantle
or jacket surrounding the fire-box and having lower openings p p and upper
openings jj, the latter being capable of regulation or adjustment as to their
size by means of a moveable ring k, a protecting plate i mounted below the oven h
within the firebox, and a tube f mounted within the stove and provided with
an exterior spiral flange b a cover f¹, a safety device and with outlet cocks g g¹
substantially as described.
2: In a stove the combination of a shell, made in sections a aa and having
the spiral flange cast on the interior thereof substantially as described.
3: In a stove the combination of a mantle a¹ to enclose the shell a, said
mantle being closed on to the shell at the top and bottom as specified, and
serving as a water boiler, substantially as described.
4: In a stove the combination of a double fire door, the two parts of which
are arranged to be slid apart when the door is to be opened substantially as
. described and for the purpose specified.
5: The stove constructed substantially as described and illustrated in the
accompanying drawings.
