Improvements in Heating Stoves or Radiators.
A communication to me from HUGO CAESAR, of Malaja Possadskaja Nr. 7, St.
Petersburg, in the Empire of Russia, Engineer.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent Agents
and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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 and accompanying drawing, that is to say:-
The heating arrangements ordinarily heretofore used for the rooms of dwelling
houses, such as those in which steam or hot water are used, or earthenware stoves,
each possesses advantages which are combined in the apparatus which forms the
subject of the present invention.
For this purpose a system of wrought iron tubes is used, so arranged that each
set of two tubes, one inside the other, is surrounded by an outer casing of earthen-
ware or porcelain, a space between the latter and the outer tubes being filled with
loose sand.
By this method of arrangement the following relative proportion of the heat is
utilized; If the temperature of the steam in the inner wrought iron tube reaches
to 100 to 105° C., the temperature of the outside of the earthenware casing is
about 65° to 70° C., a temperature which is usual in ordinary hot water heating
apparatus or earthenware stoves.
Or, by using low pressure steam heated to from 140° to 150° C., the temperature
of the outside of the earthenware casing will be 100° to 105° C.
It is essential that in the improved arrangement a too quick cooling of the
heating apparatus should not take place, as is the case where direct steam heating
is used, and by the arrangement of the earthenware casing and the thickness of
sand inside, the heat is maintained for a long time.
A still greater advantage of such a stove is that the heating parts of the apparatus
are always kept clean and bright, with very little trouble, and no disagreeable
vapours or odours are given out, as there is no metal part covered with paint,
lacquer, or bronze, and the stove causes no dirt or annoyance in the room where
it is used.
In the accompanying drawing, which is in illustration of the invention:---
Figure 1 shows the arrangement and relative proportions of the iron tubes in
the earthenware casing;
Figure 2 is a longitudinal section through a stove or radiator;
Figure 3 is a transverse section of the same;
Figure is a plan of the apparatus;
Figure 5 is a front view of a stove made ornamental.
The base a for the system of tubes has two chambers B and C.
The chamber B serves for the reception of steam admitted through an adjustable
regulating valve, and for its distribution to the inner steam tubes D. The steam
passes up through these tubes which are open at their upper ends, and displaces
the air in the upper closed ends of the outer steam pipes E, and as it becomes

be drawn off. The pipes D and E are held by a plate F which can be covered
with sand.
The earthenware pipes or casings G can be made as ornamental as desired in
their appearance, and the architectural or other design of the entire stove may be
varied as desired, without being confined to the precise shape shown in the drawing.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The arrangement of a casing of earthenware, or porcelain, or the like, round
steam heating apparatus with a thickness of sand or the like material between
them, for retaining and equalizing the heat, so as to form a stove by which the
heat of the steam introduced through a regulating valve, is distributed and utilized,
substantially as described and illustrated.
2. The arrangement of a casing of earthenware, porcelain, or the like, outside
steam heating apparatus described and claimed in Claim 1, of any desired archi-
tectural or ornamental shape or design, substantially as described and illustrated.
