An Improved Device for Producing and Burning Acetylene Gas.
I, JUSTUS WINDM" LLER of the Firm of Windmüller and Co., Commandit
Gesellschaft, of Hansaring 82/84, Cologne in the Empire of Germany, Manufac-
turer, 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 improved apparatus for producing acetylene gas.
In ane annexed drawing:-Fig. 1 shows the apparatus in combination with a
cycle lamp and a regulator g. Fig. 2 is a longitudinal section of the apparatus
and Fig. 3 is a cross section on line 3-3 of Fig. 2.
The upper part of the apparatus a serves as a water receiver, the production
of the acetylene gas taking place in the lower part.
By means of a cylindrical tube a¹ in the lower part of the apparatus an annular
space is formed between the exterior of this tube and the interior sides of the
apparatus a, into which space water coming from the upper part enters and
passes into the interior of the tube a' through the opening a³ provided near
the under end of the tube a¹. The upper end of the tube a is connected to the
cross plate b.
The space formed by the interior of the tube a¹ is in connection by means of
an opening in the plate b with a tube e, which placed in the upper part of
the apparatus a is connected with a cock h.
In the space within the cylindrical tube a¹ a tubular piece d is inserted which
is open at the top, and provided with a lateral slot and stands by means of a
foot on the bottom of the socket which closes the apparatus at its under end.
This piece d serves for receiving the composition for producing the gas.
The apparatus is also provided on the top with an opening closed by a per-
forated screw cap a which serves also as a safety valve. Through this opening
water is introduced into the apparatus on removing the screw cap.
The generator is put in connection with the lamp by means of a rubber tube r
which is attached to the cock hand in which tube a rubber ball g serves as a
regulator (this ball is more or less inflated according to the gas pressure), and
the gas developed in the producer is lighted in the lamp.
The lamp has between its casing 1 and the plate s a free space through which
air is admitted unhindered and also the burner f¹ carried by a bridge f fixed
on the casing reaches only partly into the casing.
The apparatus operates in the following manner.
The water passing from the upper part of the apparatus a through the annular
space downwards enters through the opening a³ into the lower part of the interior
of the tube a¹ and slowly impregnates the composition in the inserted piece d,
so that a successive development of the gas takes place. Owing to the arrange-
ment, that the water is always between the exterior casing of the apparatus and
the inner tube a', the apparatus cannot become over heated. The gas pressure
itself regulates the admission of water and thus the production of the gas.
As soon as the lamp connected with this gas producer is extinguished and the

page_text: cock h closed, the further developing gas will prevent (by means of the increased
pressure consequently the water from passing through the opening a³ and thus
a further development of gas is rendered impossible. On the extinc-
tion of the flame the production of the gas is interrupted. By
opening or closing the cock hand by lighting or extinguishing the lamp,
the operation or interruption of the working of the apparatus is effected that
is to say the gas production. Also when regulating the flame by the cock a
corresponding quantity of gas is produced. The gas passing through the cock h
passes through the rubber tube provided with the regulator g to the lamp,
where it is lighted. Fluctuations in the pressure are completely avoided by the
rubber ball g.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is: -
1. An improved apparatus for producing acetylene gas in which the upper
part serves as water receiver, whilst the always cooled under part provided with
a double wall serves for receiving the inserted piece d containing the material
from which the gas is evolved the water receiver being connected by means of
an opening a³ on the under end of the under part with the interior space con-
taining the inserted tubular piece and the pressure of the developed gas after
closed the cock being sufficient to hinder. the further admission of the water and
to interrupt the gas production.
2. In combination with a lamp and the gas producing apparatus substantially
as above described in Claim 1, of a hollow rubber ball inserted in the connecting
pipe between the gas producer and the lamp and serving as gas pressure
regulator.
3. The combination with the gas producing apparatus substantially as above
described in Claim 1, of a lamp in which an air chamber is provided between
the casing and the disks and the burner reaches only partly into the casing.
