Improved Acetylene Gas Generator and Apparatus.
-
I, LUDWIG PARTL, of Kertész utcza 32, Budapest, Hungary, Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of the present application consists of an acetylene gas generator
applicable both for separate lamps and also for systems with tubular connec-
tions for a number of lights.
The invention may be carried out in various forms some constructional modi-
fications of which are hereinafter described.
The generator consists of a suitable water vessel placed within a gasometer bell
or cover. Above the said water vessel a carbide receptacle is suspended. The said
carbide receptacle has a discharge opening underneath normally closed by means
of a stopper or valve. The said closing apparatus is fixed upon the gas-tube the
lower end whereof opens above the level of the water in the receptacle and serves
to conduct the gas evolved to the gasometer. The closing piece could, however,
also be fixed upon a simple rod or bar and the gas might be conducted to the
gasometer in some other way. The closing piece is preferaably connected to the
gasometer bell by such mechanical means that on the said bell sinking the
opening for the carbide is automatically opened; the rise of the bell on the other
hand automatically closes the same. For this purpose the closing piece is con-
nected with the bell either in a fixed manner or not fixed. The invention is
capable of sundry modifications, in one of these the gas-tube together with the
closing piece for the carbide receptacle is supported vertically adjustable in the
cover of the said carbide receptacle. A float is connected to the gas-tube in such
a manner that it continuously presses the said tube upwards and causes the
washer attached thereto to be permanently pressed against the opening in the
cover, so that the carbide in the receptacle is shut off air-tight and may be pre-
served for a long time. When the gasometer bell sinks through the consumption
of the gas it carries with it the gas-tube and causes the upper end thereof to
move downwards and thus opens the closing valve of the carbide outlet.
As soon
as the carbide is sufficiently discharged the bell will again rise, the tube is
released and raised to its original position by the float thus closing the opening
for the carbide again.
In another modification applicable especially to arrangements in which the gas
is generated at a distance from the consuming point or points the gas accumulated
in the bell is transmitted to the place or places of consumption through a flat-
tened tube and this either directly or with interposition of purifying apparatus.
Above the closing piece is attached another tube in order to assist the rising of
the closing piece. When the aforesaid closing piece and the gasometer bell are
connected together the upper end of the auxiliary tube is attached to the bell so

page_text: that the communication between the said tube and the said bell is effected through
apertures in the upper part of the tube. In this modification the float is done
away with and the outlet for the carbide is opened directly by means of the bell
itself when it sinks and closed again when it rises. The closing device is capable
of various modifications. In one form it is constructed of prismatic shape fitting
in the carbide outlet and placed adjustably upon the gas-tube. Above the same
is placed, also adjustably, a projection which closes the outlet of the carbide
receptacle at the end of the movement of the closing device in order to prevent
any excessive discharge into the generator. The greater the distance between
the closing device and the auxiliary projection aforesaid the more carbide will be
delivered to the water in the generator. Consequently these parts may be adjusted
to suit the consumption of gas. The closing piece is provided with a guide so
that on rising to the bottom of the carbide receptacle it is not liable to stick. In
another modification the closing piece is constructed together with the projection
in a single piece. This form of the apparatus has at its lower end a shape adapted
to fully close the outlet of the carbide receptacle and this stopper diminishes in
section upwardly so that the more the closing piece is depressed the greater the
area of the opening. Consequently the lower this piece is fixed upon the tube
aforesaid the more rapidly will the discharge opening increase in size so that this
arrangement is also capable of being adjusted to suit the consumption of the gas.
In another modification the closing device is provided with two parallel surfaces
serving as the guides and in this arrangement a special guide is not requisite.
Or it may be constructed with all the surfaces sloping as for instance wedge-
shaped, pyramidal, conical or the like, but in this case a special guide will be
requisite.
A further modificationof the closing device is as follows: On the tube already
mentioned a loosely adjustable disc is placed, which disc is supported by a weak
spiral spring. The said disc has a somewhat larger diameter than the outlet so
that when the generator bell is raised the disc completely covers the outlet and if
the bell rises still further the spring is compressed.
When the bell sinks
through the consumption of the gas the said disc is removed from the opening
and the carbide is again discharged into the generator. For the purification of
the gases developed filters of special construction may be adapted to the above
described generator. The first filter is preferably placed at the lower aperture
the gas conducting tube and the second filter immediately in front of the main
valve. These filters or scrubbers may be saturated with substances adapted to
purify the acetylene gas. A screen serves to keep the carbide from the first
filter and to cause the said carbide to pass sideways to the generator water.
second filter is preferably of cotton-wool, felt, or the like and by removing the
gas valve can easily be emptied and re-charged. For the further assistance of
the motion of the closing piece the following device may also be made use of:
Inside the carbide receptacle is placed another tube surrounding the gas tube
aforesaid but not sharing in its movements. By this means the carbide enter-
ing the generator is kept away from the gas-tube and the motion of the latter
is thereby assisted causing the pressure of the gas to become more uniform.
The outer tube is placed upon feet which do not hinder the access of the carbide
to the outlet. In order to prevent any water deposited on the bottom of the
carbide receptacle from reaching the opening it is advisable to arrange a little
ring surrounding the said opening and preventing any water from reaching the
same.

I, LUDWIG PARTL, of Kertész utcza 32, Budapest, Hungary, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
The object of the present invention consists of an improved apparatus for the
production of acetylene gas, which apparatus is suitable for use either in the case
of a single lamp or for the production of gas for the supply of several lights.
In the accompanying drawings a single lamp of the improved construction and
a stationary generator is illustrated.
In these drawings:
Figure 1 represents a vertical section of a single lamp.
Figures 2 and 3 details of the same.
Figure 4 a stationary generator, and
Figure 5 a detail thereof.
The generator is arranged inside the gasometer bell a and consists of a water-
holder b above which is arranged the carbide holder c. The connecting tube c
which is attached to the gasometer bell and communicates through apertures r
with the interior of the said bell, penetrates the carbide holder and is provided
with two adjustable closing pieces which on the sinking of the bell leave the
outlet for the carbide free and when the bell rises close it again automatically.
The closing piece n has for its object to prevent over-charging. In order to
assist the motion of the tube e in the carbide holder and thereby to render the
regulation of the feed more sensitive, the tube e is surrounded in the carbide
holder with another tube r which keeps the material away from the tube e so
that the motion of the latter is not checked. The tuber rests at the bottom of
the carbide holder upon feet between which the carbide can freely approach
the exit.
A strainer y may surround the end of the tube e as shewn in Fig. 1.
Figure 2 illustrates an alternative construction of the closing piece d in which
the said piece consists of a disc d (Figure 2) having a somewhat wider bore than
the outer diameter of the tube e, which disc rests upon a weak spring w. When
the bell sinks the disc d is moved from the carbide outlet (Figure 4) and the
carbide falls into the generating water; when the bell rises the disc d closes the
carbide outlet and fits well to the opening being gently pressed against it by the
spring w.
In Figure 3 there is illustrated the connection of the tube e with the gaso-
meter bell in vertical section, having a filter t arranged under the cock, which
filter cleanses the escaping gas.
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:-
1. An improved acetylene gas generator having a gas conducting tube such
as e attached to the gasometer bell and passing through the carbide holder, and
which conducts the gas liberated directly into the gasometer bell a and is pro-
vided with adjustable closing pieces such as d n for the purpose of automatically
regulating the supply of carbide according to the amount of gas in the holder.
2. In an acetylene gas generator of the type set forth the provision of the
tuber inside the carbide holder, and surrounding the gas pipe e in such a manner

page_text: as to keep the said pipe e from contact with the carbide and permit the carbide
free access to the discharge opening.
3. In acetylene gas apparatus of the type set forth, the movable disc d held
by spring pressure against the orifice of the carbide holder c, substantially as
set forth.
4. The combination of parts forming the improved acetylene gas apparatus and
generator constructed and operating substantially as set forth.
