Improvements in Apparatus for Producing Acetylene
I, GUSTAV VOIGT of 12 Neuenburger-strasse, Berlin in the Empire of Germany,
Manufacturer, do hereby declaro the nature of this invention to he as follows:-
This invention relates to an apparatus for producing acetylene gas which is
developed by the dripping of water on calcium carbide; it has for its object a
convenient handling, a simple and automatic arrangement, and an exact regulation
of the supply of water to the carbide receptacles, which are protected against the
interference of unauthorised persons.
Frames or supports and a gasometer are mounted on a bed plate. The one
frame carries a plate to which the carbide receptacles are airtightly attached in
such a way as to be easily removable, so that the plate forms the cover of the
receptacles. Water feed pipes and pipes for carrying off the gas open into the
plate. The feed water pipes connect with a reservoir which supplies the water for
developing the gas, and the water of said reservoir also cools the gas which is
passed through a worm immersed therein. These feed pipes through which the
water trickles on to the carbide, have each an ordinary stop cock, capable of being
closed by hand, and also a second cock operated by gearing from the gasometer.
This gearing may be arranged in any suitable manner. For instance, it may
consist of two sectors mounted on the spindles of the cocks to be operated, said
sectors being 60 curved on its periphery at two parts as to embrace a revolublo
disc and be held thereby in one or other of two positions but without preventing
rotation of the disc. The said disc has a stud or pin o in front of a slot or recess
formed in the disc, which pin engages in a slot formed in the aforesaid sectors in
order to carry the latter to right or left along with it. On the spindle of the disc
is mounted a cogwheel to engage with a rack which is firmly connected with the
gasometer and is so adapted as to operate the cocks according to the position of
the gasometer bell.
The gasometer bell is immersed in the liquid of the gasometer and receives the
gas through a pipe, which after passing through the reservoir is carried down
again in order to open freely beneath the bell.
The mode of operation is as follows :—
When the gasometer bell is in its lowest position, that is to say, when the supply
of gas is small, water from the reservoir trickles onto the calcium carbide as soon
as the stop cocks are opened. Acetylene gas is then developed, which is cooled
by means of the worm, and, if necessary, purified, and flows under the gasometer
bell. The gasometer bell rises and at a given position, by means of the gearing,
closes simultaneously or in succession the other cocks. The supply of water to
the carbide vessels is thereby interrupted, and during the subsequent development
of the gas, which causes the gasometer bell to rise still higher, the cocks are kept
firmly closed. When so much gas is consumed that the bell has descended
sufficiently, the water supply is again opened and the development of gas.
commences afresh.
The number of carbide receptacles may be increased according to requirements.

page_text: 1, GUSTAV VOIGT of 12 Neuenburger-strasse, Berlin in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what mannor
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 producing acetylene gas which is
developed by the dripping of water on calcium carbide; it has for its object a
convenient handling, a simple and automatic arrangement, and an exact regulation
of the supply of water to the carbide receptacles, which are protected against the
interference of unauthorised persons.
In the accompanying drawings,
Figure 1 is a front elevation of the apparatus with 2 carbide receptacles and
Figure 2 is a side viow.
Frames or supports and a gasometer bare mounted on a bed plate p. The
one frame carries a plate s to which the carbide receptacles are airtightly
attached in such a way as to be easily removable so that the plate forms the cover
of the receptacles. Water feed pipes c and pipes e for carrying off the gas open
into the plate p. The feed water pipes connect with a reservoir d which supplies
the water for developing the gas, and the water of said reservoir also cools the gas
which is passed through a worm to immersed therein. These feed pipes c through
which the water trickles on to the carbide, have each an ordinary stop cock f
capable of being closed by hand, and also a second cock i operated by gearing
froin the gasometer.
This gearing may be arranged in any suitable manner. For instance, it may
consist as in this case of two sectors & mounted on the spiudles of the cocks i to be
operated, each of said sectors being so curved on its periphery at two parts as to
embrace a revoluble disc and be held thereby in one or other of two positions but
without preventing rotation of the disc. The said disc has a stud or pin o in front
of a slot or recess formed in the disc which pin engages in a slut formed in the
aforesaid sectors k in order to carry the latter to right or left along with it. On
the spindle of the disc is mounted a cog-wheel m to engage with a rack n which is
firmly connected with the gasometer bell g and is so adapted as to operate the
cocks according to the position of the gasometer bell.
The gasometer bell 7 is immersed in the liquid of the gasometer b and receives the
gas through a pipe e which after passing through the reservoir d is carried down
again in order to open freely beneath the bell.
The mode of operation is as follows:-
When the gasometer bell is in its lowest position, that is to say, when the supply
of gas is small, water from the reservoir à trickles onto the calcium carbide as
soon as the stop cocks are opened. Acetylene gas is then developed, which is
cooled by means of the worin to, and, if necessary, purified, and flows under the
gasometer bell g. The gasometer bell rises and at a given position, by means of
the gearing klo closes simultaneously or in succession the cocks i. The supply of
water to the carbide vessels is thereby interrupted, and during the subsequent
development of the gas, which causes the gasometer bell to rise still higher, the
cocks are kept firmly closed. When so much gas is consumed that the bell has
descended sufficiently, the water supply is again opened and the development of
gas commences afresh.
The number of carbide receptacles may be increased according to requirements.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is :-
1. An apparatus for producing acetylene gas characterised by the bell (9) of
the gasometer (6) being adapted to automatically aud exactly close and open
taps (i) for the supply of water to the carbide receptacles by means of a
gearing klo, as soon as the said bell has reached a given height, the cocks being
retained in their end position on the further movement of the bell, substantially as
bereiubefore described.
2. In an apparatus for producing acetylene gas such as described, suspending
the carbide receptacles (a) from a plate or cover (s) which parries the water and
gas pipes, and utilizing for cooling the gas the water which serves for evolving the
gas, substantially as hereinbefore described.
