Improvements in Generators for Acetylene Gas.
I, SZYMON KON, of 22 Senatorska, Warsaw, in the Empire of Russia,
Manufacturer, 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 an apparatus for the generation of acetylene gas, in
which the generation of the gas is regulated automatically by means of the gas-
holder bell, and the gas is mixed with air in a safe manner before it passes into
the main or service pipe.
The accompanying drawing illustrates one arrangement of the improved
apparatus:-
Figure 1 being a general arrangement in section while,
Figures 2, 3, 4, and 5 are views of details.
The generated acetylene gas flows from the generating vessel through the
piper into the annular space in the bell g which is guided in the receptacle & filled
with water. The generating vessel receives its charge of water from the vessel b
through a supply pipe z that is provided with a cock h. The carbide is charged
into a perforated trough or basket t which is suspended on a rods that passes
through a stuffing box. At the bottom of the vessel e there is provided a cock for
discharging residual matters.
For the purpose of automatically regulating the generation of the gas to corre
spond with the position of the gasholder bell, i.e., with the consumption of the gas,
the rod s of the carbide trough is provided with two stops or projections a¹ a³ and
the bell is fitted with regulating device m; and a corresponding or co-operating
disengaging device n is provided on the vessel. The regulating device has two
spring fork-arms f, (Figure 2) which are kept together by means of a spring.
These arms bear against the stop a' so as to push the rod downward, or they engage
with the stop a from underneath so as to raise the said rod. In the former case
which occurs when the consumption of gas is considerable, the carbide trough is
immersed in the water so as to cause the generation of gas to take place anew.
In the latter case when the bell is at a certain height that is to say when there is
a sufficient quantity of gas in the holder, the carbide trough is raised out of the
water.
The disengaging device has in this connection the function of spreading apart;
by means of its wedge shaped end (Figure 3), the spring arms of the regulating
device, when the rod has arrived at the end of its stroke, so as to cause the arms
to release the stop, and thus allow the bell to rise still higher while the gas
continues to be generated. The rod s is held stationary by the friction in the
stuffing box.
The cock k which is provided on the acetylene gas pipe leading from the vessel e,
is preferably connected with the hermetically closing cover of the vessel, as shown
by way of example in Figures 4 and 5.
The cover is fitted with a rotary fastening device, with a strap or bridge-piece
between the legs of which the lever of the cock is arranged in such a manner that
the cock is closed when the cover is unfastened, whilst the said cock is opened
when the cover is fastened.
For the purpose of mixing the acetylene gas with air, which is of great
importance for the use of the gas for illuminating as also for heating and motive
power purposes, the bell carries in its interior an air cylinder c which draws in air

page_text: through the air pipe when the bell rises, and allows said air to escape through
the U-shaped pipe u into the annular space where the air becomes mixed in the
nozzle d with the acetylene gas.
The mixture of acetylene gas and air is conveyed by the pipe v to the place
of use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is-
1. An acetylene gas generator in which the gasholder bell carries an air
cylinder c, the arrangement being such that the acetylene gas on entering the
main or service pipe v becomes mixed with air that is under the same pressure.
2.. In the generator specified in Claim 1, the arrangement of a device for
automatically regulating the generation of the gas in the generating vessel, the
arrangement being such that the carbide trough t which dips in the water, is
mounted on a rod s which is provided with projections or stops a¹ a² said rod being
adapted to be actuated by means of a regulating device that is fixed on the bell g
and is operated by a disengaging device n.
3. An acetylene gas generator substantially as herein before described and
illustrated.
