I, MAX MOSES, Merchant, of Cologne, Blaubach 48, in the Province of Rhine-
land and Kingdom of Prussia, do hereby declare the nature of this invention to
be as follows:-
The acetylene gas generator which is the object of the present invention is
distinguished from other similar apparatus by the simplicity and cheapness of its
construction, being at the same time extremely easily and cheaply worked and
perfectly reliable and free from danger.
In the drawing Fig. 1 shows an elevation, Fig. 2 a vertical section, Fig. 3 the
top view of the complete apparatus, while Fig. 4 gives a cross-section through
the water tank, the two gas-holders and the carbide reservoir.
The apparatus consists essentially of four parts, the water tank a, the outer
gas-holder b, the inner gas-holder c, and the carbide reservoir e.
The water tank is a simple cylindrical vessel, open at the top, and having at
its upper margin towards the outside a cup-margin d for receiving the water
that may be displaced on the gas-holder being dipped in for the first time.
Outside at the upper margin of the reservoir a or the water-cup there are
secured two slide-rails f connected above by a cross-sleeper g. The sole object
of the latter is to give a greater hold to the slide-rails and to hold them fast at
the right distance.
The bell b has the shape of an ordinary gas-holder bell, i.e. that of a cylindrical
open vessel entirely closed at the top except for a circular opening to let through
the second inner gas-holder. On rising and descending the bell b is guided, partly
in the water tank a, either directly or by the use of special slides or rollers, partly
by guide rollers q placed on the roof of the bell, the edges of 9 holding the
above-mentioned slide-rails f and making an exact guide when the bell moves
up and down. On the roof of the bell there is an air-cock m and a stuffing box n
the object of which is explained later on.

The inner gas-holder has the shape of a cylinder more high than wide, which
is connected below by a conical intermediate piece with an enlarged lower part
closed by a bottom r. Above, however, it has an easily removeable, close fitting
cover h, in which there is a safety-valve p. In case of too much gas being.
developed or too little being withdrawn, when the bell has reached its highest
position this safety-valve p strikes against the cross rod g, thereby becoming
opened and allowing the superfluous gas to escape. This gas-holder c is tightly
soldered, riveted or screwed together with the outer gas-holder b just below the
flange on the upper margin on which the cover h fits, thus forming one piece with b.
By means of a tube placed outside the reservoir b and supplied with a cock,
the gas is conducted from tank c to tank b.

page_text: From here the gas flows through a tube a reaching above the level of the water
and carried through the bottom of the water tank a to the gas-pipe which is
to be connected with it.
The carbide holder e has likewise the shape of a tall narrow cylinder closed
below with perforated sides and bottom, as shown in the drawing, and made of
woven wire. Below its upper margin there is a flange which lays itself on an
edge in the inner gas-holder e, so that the carbide holder hangs freely suspended
in the chamber c.
In the bottom of the tank c is close to the outer margin an opening formed like
a conical valve seat. The cone valve & fitting into it is opened or closed, as needed
for the generation of gas, by means of a rod passing through the conical middle.
piece in the outer gas-holder 6 and from here through the above-mentioned stuff-
ing-box n into the open air.
When the valve is open, water enters from the bottom into the gas-holder c
and thus reaches from all sides, with more or less force, the calcium carbide con-
tained in c, thus causing the gas to generate.
If more gas is generated than is used, then, as is also the case in other acety-
lene gas generators, the bell b rises, and with it also the inner gas-holder c, thus
gradually bringing the calcium carbide out of the water, until at last the gas
ceases to generate. The generation of gas commences again when the supply of
gas stored in the bell is consumed and the bell has sunk correspondingly in
the water.
By means of the valve kit is now possible to allow only a certain quantity of
water, also when the bell is low down-to reach the carbide, or else to shut off
the water supply altogether, so that the generation of the gas can be better regu-
lated and stopped more suddenly than was hitherto the case, when the chamber
was always quite open at the bottom.
If the amount of gas used becomes greater than the amount that is being
generated at the time, the bell sinks proportionately deeper into the water, where
on the one hand the valve k is automatically raised i.e. opened by the rarification
of the gas in the interior of c, on the other hand by the force of the water pushing
up from below so that by the fresh water entering in considerable quantities and
acting on the carbide, a greater amount of gas is generated either in proportion
to the demand or in excess of it, which on its parts, causes the bell b to rise
again.
If the generation of the gas proceeds too quickly in proportion to its consump-
tion the consequent higher tension in the interior of the chamber c, is sufficient
to act as a closed air-cushion on the water in the lower part of c, and therefore
to press it out through the opening of the valve, and thus not to allow fresh
water to enter. Thus the amount of gas generated is continually being regu-
lated in accordance with the amount consumed.
The working of the apparatus is simply as follows:
After the cross-piece g, which is secured in any way desired to the slide-rails,
has been removed, the gas-bell b—the air-cock m being open, the valve closed
and the cock in the connecting tube i being closed-is pushed into the slide-
rails and placed into the water tank a. Then the full carbide holder e, after
the cover has been removed, is put into the inner tank e.
If the valve and the cock in the connecting tube i is now opened, the gas
commences to generate when the gas that is being generated has displaced the
air at the top under the roof of the bell b, which is known by the escape of
acetylene gas-clouds or smoke from the air-cock m, the latter is closed and the
gas now enters the supply pipe which up till now must be shut off.
When the calcium-carbide in the holder e is used up, and the generation of the
gas has ceased, the opposite manipulations are carried out. The valve and the
cock in the connecting tube is closed, the cover is opened, the carbide-
holder e is taken out, and the sand or foam-like stuff, the solid refuse of the

the holder is freshly filled and again put in.

I, MAX MOSES, Merchant, of Cologne, Blaubach 48, in the Province of Rhine-
land and Kingdom of Prussia, 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:-
The acetylene gas generator which is the object of the present invention is
distinguished from other similar apparatus by the simplicity and cheapness of its
construction, being at the same time extremely easily and cheaply worked and
perfectly reliable and free from danger.
n the drawing filed with the Provisional Specification Fig. 1 shows an eleva-
tion, Fig. 2 a vertical section, Fig. 3 the top view of the complete apparatus,
while Fig. 4 gives a cross-section through the water tank, the two gas-holders
and the carbide reservoir.
The apparatus consists essentially of four parts, the water tank «, the outer
gas-holder b, the inner gas-holder c, and the carbide reservoir e.
The water tanka is a simple cylindrical vessel, open at the top, and having at
its upper margin towards the outside a cup-margin for receiving the water
that may be displaced on the gas-holder being dipped in for the first time.
Outside at the upper margin of the reservoir a or the water-cup d there are
secured two slide-rails f connected above by a cross-sleeper g. The sole object
of the latter is to give a greater hold to the slide-rails and to hold them fast at
the right distance.
The bell has the shape of an ordinary gas-holder bell, i.e. that of a cylindrical
open vessel entirely closed at the top except for a circular opening to let through
the second inner gas-holder. On rising and descending the bell b is guided, partly
in the water tank a, either directly or by the use of special slides or rollers, partly
by guide-rollers g placed on the roof of the bell, the edges of q holding the
above-mentioned slide-rails f and making an exact guide when the bell moves
up and down. On the roof of the bell there is an air-cock m and a stuffing-box n
the object of which is explained later on.
The inner gas-holder.c has the shape of a cylinder more high than wide, which
is connected below by a conical intermediate piece with an enlarged lower part
closed by a bottom, r. Above, however, it has an easily removeable, close fitting
cover h, in which there is a safety-valve p. In case of too much gas being
developed or too little being withdrawn, when the bell has reached its highest
position this safety-valve p strikes against the cross-rod g, thereby becoming
opened and allowing the superfluous gas to escape.. This gas-holder e is tightly
soldered, riveted or screwed together with the outer gas-holder just below the
flange on the upper margin on which the cover h fits, thus forming one piece with b.
By means of a tube i placed outside the reservoir b and supplied with a cock,
the gas is conducted from tank c to tank b.
From here the gas flows through a tube o reaching above the level of the water

page_text: and carried through the bottom of the water tank a to the gas-pipe which is
to be connected with it.
The carbide holder c has likewise the shape of a tall narrow cylinder closed
below with perforated sides and bottom, as shown in the drawing, filed with the
Provisional Specification, and made of woven wire. Below its upper margin there
is a flange which lays itself on an edge in the inner gas-holder e, so that the
carbide holder hangs freely suspended in the chamber c.
In the bottom of the tank c is close to the outer margin an opening formed like
a conical valve seat. The cone valve k fitting into it is opened or closed, as needed
for the generation of gas, by means of a rod 7 passing through the conical middle
piece in the outer gas-holder 6 and from here through the above-mentioned stuff-
ing-box into the open air.
When the valve is open, water enters from the bottom into the gas-holder c
and this reaches from all sides, with more or less force, the calcium carbide con-
tained in c, thus causing the gas to generate.
If more gas is generated than is used, then, as is also the case in other acety-
lene gas generators, the bell rises, and with it also the inner gas-holder 2, thus
gradually bringing the calcium carbide out of the water, until at last the gas
ceases to generate. The generation of gas commences again when the supply of
gas stored in the bell is consumed and the bell has sunk correspondingly in
the water.
By means of the valve k it is now possible to allow only a certain quantity of
water, also when the bell is low down-to reach the carbide, or else to shut off
the water supply altogether, so that the generation of the gas can be better regu-
lated and stopped more suddenly than was hitherto the case, when the chamber
was always quite open at the bottom.
If the amount of gas used becomes greater than the amount that is being
generated at the time, the bell sinks proportionately deeper into the water, where
on the one hand the valve k is automatically raised i.e. opened by the rarification
of the gas in the interior of c, on the other hand by the force of the water pushing
up from below so that by the fresh water entering in considerable quantities and
acting on the carbide, a greater amount of gas is generated either in proportion
to the demand or in excess of it, which on its parts, causes the bell to rise
again.
If the generation of the gas proceeds too quickly in proportion to its consump-
tion the consequent higher tension in the interior of the chamber c, is sufficient
to act as a closed air-cushion on the water in the lower part of c and therefore
to press it out through the opening of the valve, and thus not to allow fresh
water to enter. Thus the amount of gas generated is continually being regu-
lated in accordance with the amount consumed.
The working of the apparatus is simply as follows:
After the cross-piece 9, which is secured in any way desired to the slide-rails,
has been removed, the gas-bell the air-cock m.being open, the valve k closed
and the cock in the connecting tube i being closed is pushed into the slide-
rails and placed into the water tank a. Then the full carbide holder e, after
the cover has been removed, is put into the inner tank c.
If the valve and the cock in the connecting tube i is now opened, the gas
commences to generate when the gas that is being generated has displaced the
air at the top under the roof of the bell b, which is known by the escape of
acetylene gas-clouds or smoke from the air-cock m, the latter is closed and the
gas now enters the supply pipe which up till now must be shut off.
When the calcium-carbide in the holder e is used up and the generation of the
gas has ceased, the opposite manipulations are carried out. The valve and the
cock in the connecting tube i is closed, the cover his opened, the carbide-
holder e is taken out, and the sand or foam-like stuff, the solid refuse of the
decomposition of the carbide which sticks in the mesches of e is removed. Then
the holder is freshly filled and again put in.

page_text: 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:
Acetylene gas generator thereby characterized that the chamber c placed in
the bell and containing the carbide-holder e and supplied at the top with a
detachable cover c and closed below by a bottom in which a valve, actuated
at will from the outside but in case of rarification of the gas in the bell opened
automatically by the pressure of the water, alternately allows the water to reach
the carbide or shuts it off, whereby a better and quicker regulation of the gas
generation in proportion to its consumption is obtained than by the sole rising and
sinking of the bell, the carbide-holder being open at the bottom.
