IMPROVEMENTS IN GENERATORS FOR HYDROCARBON ENGINES
Year: 1880

page_text: LETTERS PATENT to Israel Rudolf Blumenberg, of Washington, in the District
of Columbia, United States of America, but at present of 33, Chancery Lane,
in the County of Middlesex, for an Invention of "IMPROVEMENTS IN GENERATORS
FOR HYDROCARBON ENGINES."
PROVISIONAL SPECIFICATION left by the said Israel Rudolf Blumenberg at
the Office of the Commissioners of Patents on the 17th November 1880.
ISRAEL RUDOLF BLUMENBERG, of Washington, in the District of Columbia,
United States of America, but at present of 33, Chancery Lane, in the County
of Middlesex. "IMPROVEMENTS IN GENERATORS FOR HYDROCARBON ENGINES."
The object of this Invention is to produce an efficient, compact, convenient, and
fuel and labour saving generator or vaporizer of bisulphide of carbon or other
hydrocarbon, such vaporized hydrocarbon being especially used as an impelling
agent in vapour engines.
According to this my Invention I combine the boiler with the vaporizer or
generator proper all in one structure. The fire box may be circular, and is fitted
with any suitable grate or gas burner appliances, or any other suitable heat
producing appliance. On the top of this firebox there is a circular chamber with
a bottom, by preference bulged downwards, or otherwise formed with corrugations
or cups, or so as to present a large heating surface so as to economize fuel and
water. This bottom is exposed to the fire from beneath; this chamber contains
water or other liquid suitable for communicating the heat to a system of pendent
pipes closed below and fixed by screwing or otherwise to a tube plate which forms
the top of the aforesaid chamber. Or the pendent tubes may be in U form, each
shank being fixed to the tube plate.
On the top of the heating chamber containing the tubes, which dip more or less
in the liquid, there is a chamber which I call the vaporizing or spray chamber.
The bisulphide of carbon or other hydrocarbon to be vaporized is admitted into it

page_text: by a rose or other spreading appliance from the top. The holes in the rose are
preferably made slanting, and the rose is swivelled so that the jets issuing therefrom
set the rose in rotary motion, thus spreading the jets effectually and causing them
to enter the tubes. The tubes being heated from the liquid in which they dip,
cause the bisulphide of carbon to be vaporized, and this vapour is passed off to be
used in the engine or otherwise by a pipe.
The vaporizing chamber is fitted with pressure gauge, and the heating chamber
has pressure gauge, safety valve, and other usual boiler fittings.
The three parts of the apparatus, viz., the firebox, the heating chamber, and the
vaporizing chamber may be connected together by means of flanges and bolts.

ISRAEL RUDOLF BLUMENBERG, of Washington, in the District of Columbia,

The object of this Invention is to produce an efficient, compact, convenient, and
fuel and labour saving generator or vaporizer of bisulphide of carbon or other
hydrocarbon, such vaporized hydrocarbon being especially used as an impelling
agent in vapour engines. According to this my Invention I combine the boiler
with the vaporizer or generator proper all in one structure. The fire box may be
circular, and is fitted with any suitable grate or gas burner appliances, or any other
suitable heat producing appliance. On the top of this fire box there is a circular
chamber with a bottom, by preference bulged downwards, or otherwise formed with
corrugations or cups, or so as to present a large heating surface so as to economize
fuel and water. This bottom is exposed to the fire from beneath; this chamber
contains water or other liquid suitable for communicating the heat to a system of
pendent pipes closed below and fixed by screwing or otherwise to a tube plate
which forms the top of the aforesaid chamber, or the pendent tubes may be in
U form, each shank being fixed to the tube plate.
On the top of the heating chamber containing the tubes, which dip more or less
in the liquid, there is a chamber which I call the vaporizing or spray chamber.
The bisulphide of carbon or other hydrocarbon to be vaporized is admitted into it
by a rose or other spreading appliance from the top. The holes in the rose are
preferably made slanting, and the rose is swivelled, so that the jets issuing therefrom
set the rose in rotary motion, thus spreading the jets effectually, and causing them
to enter the tubes equally. The tubes being heated from the liquid in which they
dip, cause the bisulphide of carbon to be vaporized, and this vapour is passed off, to
be used in the engine or otherwise by a pipe.
The vapourizing chamber is fitted with pressure gauge, and the heating chamber
has pressure gauge, safety valve, and other usual boiler fittings.
The three parts of the apparatus, viz., the firebox, the heating chamber, and
the vapourizing chamber may be connected together by means of flanges and
bolts.
In the accompanying Drawings I have illustrated a convenient mode of carrying
this Invention into effect. Figure 1 is a vertical cross section of the generator, and
Figure 2 a vertical section of a generator connected to a steam boiler. A, Fig. 1, is
the fire box with ashpit y, furnace bars a, and smoke outlets. To the top of the
fire box A is connected by bolts g and flanges b the heating chamber B, which is
here shown with a part spherical bottom B'; the lower part of the chamber B
contains the water, and the upper part the steam; d is a tube plate bolted to the
top flange b'. A number of tubes e closed below are fixed in this tube plate and
dip into the water; ' is a feed pipe for supplying water to the heating chamber B.
The vaporizing chamber D is by flanges and bolts connected to the tube plate d
and the heating chamber B. J is a pipe for supplying the chamber DD with
bisulphide of carbon or other hydrocarbon; it terminates in a rose I, which is
swivelled, and in which the jet holes are slanting, so that the issuing jets cause it
to revolve, thus spreading the issuing liquid and causing the same to enter the
tubes e equally. The bisulphide of carbon dropping into the tubes e is vaporized,
and the vapour is carried off by the pipe K to the place where it is to be stored or
used. The chamber D is fitted with pressure gauge g', and if desired also with

page_text: safety valve. is a pressure gauge on the heating vessel, which is also fitted with
safety valve and other usual boiler fittings. The supply of bisulphide is regulated
by the valve o on the pipe J.
In Figure 21 have shewn a modified arrangement, in which the generator proper
is made separate from the source of heat, which in this case is a steam boiler A
connected to the heating chamber B of the generator by means of the pipe m from
the boiler steam space and by the pipe n from the boiler water space.
o is a valve
for regulating the steam admission, and by means of this valve o and the valve p
on the bisulphide supply pipe (which two valves may be connected by suitable
gear) I obtain perfect control over the evolution of bisulphide vapours in the
chamber D.
And having thus described and ascertained the nature of this Invention, and
the manner
in which it is or may be carried into effect, I declare that I
claim,―
First. A combined apparatus for vaporizing bisulphide of carbon or other
hydrocarbon liquid, consisting of a bottom firing chamber or fire box arranged
under a heating chamber containing water or other suitable liquid, and a space for
steam, and a system of pendent tubes closed below dipping into the water and open
to an upper chamber in which the bisulphide of carbon is supplied in a spray form
to the pendent tubes and the vapor is carried off by an outlet, substantially as set
forth.
Second. A cylindrical vessel or generator divided into an upper vaporizing
compartment and an intermediate heating compartment containing a system of
pipes which are heated externally, substantially as set forth.
Third. The construction of the heating chamber with the pendent tubes, as
described and shewn.
Fourth. The generator in combination with a steam boiler for supplying heat
thereto, as described with reference to Figure 2.
In witness whereof, I, the said Israel Rudolf Bluinenberg, have hereunto
set my hand and seal, this Fourteenth day of May, in the year of our
Lord One thousand eight hundred and eighty-one.
