improvements in Heating Apparatus.
A communication from PAUL RICHARD HORN, Manufacturer, of Dresden-Neustadt,
Saxony, German Empire.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 a hot-water stove or heating apparatus not only entirely
independent of any central heating-station but also in itself constituting a complete
self-contained heating apparatus heated by gas and consisting of a battery or range
of vertical pipes with external ribs or gills.
On the accompanying drawing,
Figure 1 is a view of the hot-water heating stove, partly in elevation, and partly
in longitudinal section ;
Figure 2 is a vertical cross section of one of the ribbed pipes, showing behind the
central tube which forms the boiler;
Figure 3 is a cross section of the fire-box (shown in Figure 1) with diametrically
arranged boiler tubes;
Figure 4 shows in elevation an arrangement of fire-tubes which may be used in
the boiler instead of that shown in Figure 3; and Figure 5 is a cross section of
the same.
In the drawings the ribbed pipes A are shown as of the ordinary construction
with oblique oval disc-shaped ribs and are joined together and supported at the end
by the pipes b and c running across their longer axis and thereby also connected
with the central pipe D which serves as a boiler.
a whole.
In this manner two horizontal pipes B and C (with closed ends) are formed
connecting the vertical pipes A'A DAA and constituting the battery or range of
pipes forming the independent self-contained heating apparatus as
Attached to the upper pipe B at one end is the thermometer T and at the other
end the expansion vessel E, together with any other needful or desired fittings.
The apparatus is enclosed in a suitably perforated case ornamented in any manner
desired, or it may be secured to the wall of a room, corridor etc.
The heating of the stove takes place by means of D, below which a gas-burner
or equivalent heating device d of any desired suitable construction is fixed, being
supplied with gas by the pipe d' fitted with a cut-off cock d³. Secured to the
bottom flange of D is the flange of the cylindrical fire-box F to the top of which
the escape pipe G of the gases and combustion products is attached and which can
as shown either find a single outlet at the top of D, or be arranged so as to divide
in two and pass through B to right and left. The firebox is traversed by a number
of diametrically arranged boiler-tubes f so varying in horizontal position one above
another (Figure 3) that their opposite ends f form two perforated spirals around
the fire-box as shown in elevation in Figure 1, and through which the water
circulates freely, while the burning gas and heated combustion products play freely
upon the outside of the tubes f.
For the same purpose the arrangement shown in Figs. 4 and 5 can be substituted
or the firebox Finside the boiler D. Herein two cylindrical end chambers H
nd H are connected by a bundle or group of vertical flue tubes h (similar to the
orizontal flue-tubes of a locomotive boiler). The gas-jet d is located in the lower
ylinder H and the escape-pipe or flue G for the combustion products is fixed to
Price 81

page_text: the upper cylinder H¹. In this arrangement therefore the flames and combustion
products ascend through the sheaf of tubes around which the water circulates
freely.
It is obvious that as regards the essential nature of this invention, it matters
nothing how many ribbed pipes A are combined to constitute the stove or heating
apparatus. In the larger class of stoves several tubular boilers D F and as many
gas-jets may advantageously be employed.
When the apparatus is in operation a constant and brisk water-circulation
is established the water will naturally be the most heated in the vicinity
of the fire-box F or fire-tubes f, and it would flow upwards, in the direction
of the arrows shown in Figure 1, issuing from D passing right and left through B
down the pipes A and so returning through C, from right and left, to the
boiler D, and so on (as long as the source of heat is maintained at the gas-
burner d) parting with its heat to the range or battery of pipes A, whence the heat
is radiated by the gills or ribs.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is ;-
1. A heating apparatus comprising a range or group of upright externally ribbed
pipes such as A through which water circulates and one or more pipes such
as D each of the latter acting as a boiler and having an escape-pipe such as G
for combustion products passing through it and heated from below by a gas or other
flame substantially as described and illustrated in the accompanying drawings.
2. In heating apparatus such as described in Claim 1 a fire-box such as F with
cross tubes (f) in the lower part of the pipe (D) and having the escape pipe (G)
secured to it at the top substantially as described and illustrated in the accompanying
drawings.
3. In heating apparatus such as described in Claim 1 the arrangement inside the
pipe (D) of two chambers such as H H' connected by a sheaf or group of flue
tubes (h) the lower chamber (H) being provided with a gas or other heating
device (d) while the upper chamber (H) forms the connection between the flue-
tubes (h) and the escape flue G of the combustion products substantially as described
and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete heating
apparatus substantially as described and illustrated in the accompanying drawings.
