Improvements in Apparatus for Heating by Hot Water.
A communication to me from FERDINAND EICKE, of 28, Waller-Chaussee,
Bremen, in the Empire of Germany, Merchant.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for heating rooms or other places by means
of hot water.
The improved apparatus is divided into three parts, namely, a generator below,
a heater or radiator above, and a compensating vessel above or near the top of the
latter. The generator consists of a vessel or boiler, preferably of somewhat larger
diameter at its upper part, which is filled with water. This water surrounds a
coiled pipe which is contained in the vessel, and to the lower end of this pipe three
pipes are attached of which two pass to the upper part of the hollow radiating
chamber above, the lower part of which chamber communicates by another pipe
with the upper end of the coil. In this way the water contained in the coil
circulates through it and through the radiating chamber above when the generating
chamber, which is supported upon feet, is heated by a burner below by means of
petroleum, spirit, gas, or other suitable fuel, the heat being transferred by the
circulation of the water to the radiating chamber.
This latter chamber is in the form of a vertical rectangular chest formed of flat
plates and provided with ribs or gill plates for the better radiation of the heat.
It is supported upon suitable feet or legs above the generating chamber below.
The third pipe communicating with the lower end of the coil leads at its upper
end to the lower part of the compensating chamber above, and the upper part of
the latter communicates by another pipe with the generating chamber below.
Moreover another pipe communicates from the bottom of the compensating
chamber to the generator below, in order that the apparatus may be filled in a
shorter time with water by means of the upper chamber.
The cover of this upper chamber is fitted loosely but sufficiently steam tight
upon it so that it serves as a safety valve, whilst the lower or generating chamber
is provided with a cover screwed tightly upon it, preferably by means of a cross bar
and strong central screw, so that the escape of water is prevented. Air-holes or
valves are provided at the upper part of the radiating chamber, opening inwards so
as to prevent the formation of a vacuum.
In a slightly modified form of arrangement the generator and radiating chamber
are arranged side by side instead of one above the other. The highest part of the
former is connected by a pipe with the lowest part of the latter, whilst another
pipe connects the lowest part of the generator with the highest part of the
radiator.
Moreover a pipe communicates from the bottom of the generator to the bottom
of a compensating chamber arranged at a sufficient height above. and finally
another pipe from the generator conducts away any steam which may be formed in
the latter.
The generator may be heated in this form of arrangement in the same way as iu
that first described.
Or the generator may be heated by means of an electric current passing through
wire soiled round the vassal the mine being of sufficient resistance so that when a

page_text: current of electricity is made to pass through it, a part of its energy is converted to
heat.

Improvements in Apparatus for Heating by Hot Water.
A communication to me from FERDINAND EICKE, of 28, Waller-Chaussee,
Bremen, in the Empire of Germany, Merchant.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, 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 :-
This invention relates to apparatus for heating rooms and other places by means
of hot water. The improved apparatus is illustrated by the accompanying drawings,
in which
Fig. 1 is a front elevation, Fig. 2 is a side elevation, and Fig. 3 is a vertical
section, Fig. 4 is a front elevation of an apparatus modified in order to be used in
rooms of small dimensions in vertical direction.
Fig. 5 represents in front elevation a modified generator.
The improved apparatus is divided into three parts, riz.: A generator A below,
a heater or radiator B above, and a compensating vessel C above, or near the top
of, the latter. The generator A consists of a vessel or boiler a preferably of
somewhat larger diameter at its upper part, which is filled with water. This water
surrounds a coiled pipe b which is contained in the vessel a, and to the lower end of
this pipe three pipes, c, d, e, are attached, of which two (namely c and d) pass to
the upper part of the hollow radiating chamber B, the lower part of which
chamber communicates by another pipe with the upper end of the coil b. In this
way the water contained in the coil circulates through it and through the
radiating chamber B when the generating chamber a which is supported upon
feet a¹ is heated by a burner g below by means of petroleum, spirit, gas, or other
suitable fuel, the heat being transferred by the circulation of the water to the
radiating chamber B.
This latter chamber is in the form of a vertical rectangular chest formed of flat
plates and provided with ribs or gill plates for the better radiation of the heat.
It is supported upon suitable feet or legs i above the generating chamber B.
The third pipe e communicating with the lower end of the coil leads at its
upper end to the lower end of the compensating chamber C, and the upper part of
the latter communicates by another pipe k with the generating chamber a.
Moreover another pipe 1, communicates from the bottom of the compensating
chamber C to the generator a in order that the apparatus may be filled in a shorter
time with water by means of the upper chamber C.
The cover m of this upper chamber C is fitted loosely but sufficiently steam tight
upon it, so that it serves as a safety valve, whilst the generating chamber a is
provided with a cover n screwed tightly upon it, preferably by means of a cross bar o
and strong central screw o', so that the escape of water is prevented. Air holes or
valves are provided at the upper part of the radiating chamber B, opening
inwards so as to prevent the formation of a vacuum.
In the slightly modified form of arrangement illustrated by Fig. 4, the generator A
and radiating chamber B are arranged side by side instead of one above the other.
The highest part of the former is connected by a pipe y with the lowest part of the

page_text: latter whilst another piper connects the lowest part of the generator A with the
highest part of the radiator B.
Moreover a pipes communicates from the bottom of the generator A to the
bottom of a compensating chamber C arranged at a sufficient height above, and
finally another pipef from the generator A conducts away any steam which may
be formed in the latter.
The generator A may be heated in this form of arrangement in the same way as
that first described.
Or the generator may be heated by means of an electric current passing through
a wire u coiled round the vessel A, Fig. 5, the wire being of sufficient resistance so
that when a current of electricity is made to pass through it, a part of its energy is
converted to heat.
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:
The combination in an apparatus for heating rooms and other places by hot
water, of a generator A, with a radiator B and a compensating chamber C,
substantially as set forth and illustrated in the accompanying drawings.
