Improvements in Boilers for Warm Water or Low Pressure Steam
Heating Purposes.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Bucking-
ham Street, Strand, W.C., Patent Agent, do hereby declare the nature of this
invention, a communication to me from abroad by Hans Schuppmann, of the
Firm of C. A. Schuppmann, of Kaiserstrasse 31, Berlin, in the Empire of Ger-
many, Manufacturer of Stoves, to be as follows:-
The object of the present invention is a boiler composed of columnar hollow
bodies of cast iron formed by addition of corner elements into a box like
chamber.
The elements thus combined form the walls of the fire box for receiving the
combustibles and also the flue for the fire gases. Only the flue or part of the
flue nearest to the chimney is bounded on the outside by cast iron plates. The
columnar corner elements opposite the fire door do not extend entirely to the
upper end boxes joining the single elements together to leave a space forming
thereby at the same time the fire bridge. The elements are fixed or movably
joined together by means of nipples or similar devices.
This boiler can be used as well for warm or hot water heating as for low
pressure steam heating and its construction is such that it can be fired with solid
liquid or gas like combustibles. In using solid combustibles the combustion
space of the boiler can be provided with a plane grate or with a shaking or
shifting grate. If the boiler is heated with coal, the elements are provided
with vertical ribs lying close together towards the feeding hopper and prolonged
to under the great plane for favoring the disengagement of the gases. The
introduction of water for warm water heating is effected from above through a
vertical tube and the elements lying beside one another are only joined together
below whilst their upper joining pieces are provided with perforated stoppers.

many, Manufacturer of Stoves, 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 boilers for warm water or low pres-
sure steam heating purposes.
In the accompanying drawing a boiler constructed according to this invention
is represented.
Fig. 1 shows this boiler in section on the line A B of Fig. 3.
Fig. 2 is a section on line CD of Fig. 3.
Fig. 3 is a plan view thereof.
The improved boiler consists of hollow columnar cast iron bodies a formed by
addition of corner elements b, into a box like chamber. The elements thus
formed or combined form the walls of the fire box d for receiving the combus-
tibles and also the flue f for the fire gases. Only the flue or part of the flue f
nearest to the chimney e Fig. 2, is bounded or encased on the outside by cast
iron plates g. The fire gases, move in the direction indicated by the arrows.
The columnar corner elements b opposite the fire door h do not extend entirely
to the upper end boxes k joining the single elements together, thus leaving a space,
forming thereby at the same time the fire bridge c (Fig. 2). The elements a
and bare fixed or movably joined together by means of nipples or similar
devices.
The boiler described can be used for warm or hot water heating as well as
for low pressure steam heating, and its construction is such that it can be fired
with solid, liquid or gas like combustibles. In using solid combustibles the
combustion space of the boiler can be provided with a plane grate or with a
shaking or shifting grate. If the boiler is heated with coal the elements are
provided towards the feed hopper with vertical ribs lying close together and
extending to below the horizontal grate space for favoring the disengagement
of the gases.
The introduction of water for warm water heating is effected
from above through a vertical tube and the elements lying beside one another
are only joined below, whilst into the upper joining pieces perforated plugs are
placed.
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. A boiler for warm water or low pressure steam heating purposes with per-
pendicular columnar elements of cast iron joined together so that their interiors
form a chamber for reception of the water to be heated.
2. A boiler for warm water or low pressure steam heating purposes with
perpendicular columnar elements of cast iron joined together so that their in-
teriors form a chamber for reception of the water to be heated, said elements
being so composed that they surround a shaft chamber for receiving the com-
bustibles.
3. A boiler for warm water or low pressure steam heating purposes with per-
pendicular columnar elements of cast iron forming with their interiors a chamber
for reception of the water to be heated and surrounding a shaft for the reception
of the combustibles, the elements being so connected that the fire gases pass
between them to the chimney.
4. A boiler for warm water or low pressure steam heating purposes with
perpendicular columnar elements of cast iron forming with their interiors a
chamber for reception of the water to be heated and surrounding a shaft for
the reception of the combustibles and being so composed that the fire gases
escape between said elements to the chimney, openings being provided in the
elements enabling the fire gases to escape from the feed hoppers into the shaft
formed by the arrangement of the elements.
5. A boiler for warm water or low pressure steam heating purposes with per-

page_text: pendicular columnar elements of cast iron forming with their interiors a cham-
ber for reception of the water to be heated and surrounding a
врасе for reception
of the combustibles, the junction between the fire space and the flue being
effected by insertion of shorter cast iron elements b.
6. The combination of cast iron columnar elements a and (shorter) cast
elements substantially as and for the purpose described.
7. The combination of cast iron columnar elements a provided with end
boxes k, cast columnar elements 6 forming passages c and the bridge for the fire
gases and a casing g substantially as and for the purpose described.
8. In boilers for warm water or low pressure steam heating purposes a cast
iron columnar element provided with end boxes k substantially as described.
9. In boilers for warm water or low pressure steam heating purposes a cast
iron columnar element provided with a recessed portion or passage c substan-
tially as described.
