Improvements in or relating to Apparatus for Heating Purposes.
A communication from BRUNO FLEISCHER, of Neu-Mickten, near Dresden, Saxony,
in the German Empire, a member of the firm of C. B. Fleischer & Co.,
Dye-wood Extract Manufacturers.
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 :-
The main object of this invention is to combine or connect directly an arrange-
ment or net-work of steam-heating pipes with a steam-generator, heated by either
Equid or gaseous hydrocarbons. This enables the heating-plant to be carried out
in a more compact form than hitherto, so as to form as it were one independent
apparatus, which may without the aid of any central source of heating-medium, be
employed for heating rooms or apartments singly and separately, and be erected
wherever required, or carried from place to place, as readily as any ordinary
complete heating-stove. The invention is therefore a combination of the advantages
of steam-heating, viz.: cleanliness, a pleasant uniform warmth, etc., and of those of
gas-heating, viz.: convenience, facility of attendance, and also cleanliness; while
an additional advantage derived from the fact that the heat given off by the
steam-generator by radiation is not lost, but assists in heating the apartinent.
The invention will be best understood by reference to the accompanying drawings
in which
Figure 1 is a sectional elevation of the apparatus, the outer casing being shown
in section and
Figure 2 is a detail plan of the burner.
Upon a common bed-plate F is erected a series of preferably rib-shaped
heating-pipes A together with the steam-generator B. In the drawings it is
assumed that the generator is in the form of a small boiler of the tubular type
(with heating-tubes), but, of course, any other form of boiler may be employed at
will. Heat is imparted by a burner C preferably constructed as will be hereinafter
more fully described. c designates a pipe for the escape of the products of com-
bustion. From the steam-chamber of the boiler B a pipe d leads to the uppermost
steam-heating pipe, while a second pipe e connects the lowest point of the series of
steam-heating pipes with the boiler to which it conducts the condensation water.
The course and direction of the steam, whether condensed or not, is indicated by
arrows. Those flange-connections through which no arrows are marked on the
drawing are closed and cut off from the circulation. ƒ is a relief-cock; g a safety-
valve and h a pressure-gauge.
An arrangement hereinafter described serves to automatically regulate the
heating of the steam-generator by cutting off the supply of fuel when required.
The burner preferably consists of a number of concentric rings provided
with perforations, though practically the same result may be obtained by the
employment of a series of parallel burner-tubes. Each ring (or each row of tubes)
is in connection with a special gas-supply pipe k k k respectively.
These pipes open, one above the other, into a cylindrical chamber / to the lower
end of which is connected the main supply pipe m. Within the said chamber / a
tightly fitting piston valve n is adapted to move, being connected by a rod o with
the lever p. This lever, which may be weighted by means of an adjustable weight q
or similarly acted upon by a spring undergoes at its lower part the action of the
piston or plunger being acted upon by steam pressure. As the pressure increases,
the piston is raised, as it decreases, the piston sinks, and these movements are

page_text: transmitted to the slide-valve n. As a given temperature corresponds to a
determined steam-pressure, the steam-pressure itself can be utilized for controlling
the supply of fuel to the burners and also consequently the production of steam.
The slide valve n is so adjusted that the pipe for the inner burner ring always
remains open. This ring therefore remains permanently lighted and serves for
keeping up the flame. As the pressure increases the pipe k and then the pipe ¹
are closed and thus the communication with the rings i and successively cut off.
According as the pressure is relieved these burners are lighted again by the
constantly lighted burner *.
Should petroleum or a similar hydrocarbon be employed for heating the pipe m
would have to be connected with a fuel reservoir arranged at a suitable height.
The supply of fuel may then be regulated by means of any suitable device. The
heating arrangement may be operated at high or low pressure as may be desired.
The whole of the apparatus should preferably be surrounded by an outer casing M.
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 steam-heating plant consisting of a series of rib-shaped pipes A directly
connected with a steam generator B provided with a burner C adapted for heating
with liquid or gaseous hydrocarbons substantially as described and illustrated in the
accompanying drawings.
2. A burner C consisting of a number of rings provided each with an
independent fuel supply k k¹² substantially as described and illustrated in the
accompanying drawings.
3. The valve n provided with a weighted piston or plunger connected to a
lever and adapted to cut off the fuel-supplies k kone after the other as the
pressure of steam increases substantially as described and illustrated in the accom-
panying drawings.
