An Improved Apparatus for Generating Acetylene-gas.
I, SÖREN CHRISTIAN SÖRENSEN, of 34, Klostergade Aarhus, in the Kingdom
of Denmark, Gas-fitter and Master Turn-cock, do hereby declare the nature of
this invention to be as follows:-
My invention relates to an improved apparatus for generating acetylene-gas
in which the calcium carbide is placed in special cases which I term cartridge-
cases, fastened outside the apparatus and easily removable.
My apparatus as is the case with other similar apparatus comprises a water-
tank in which is inserted a bell-shaped gasometer, closed at the top, in such a
way that it may move up and down, it being guided in a suitable manner.
On the bottom of the tank is placed a receiver open at the top.
Outside the water-tank are placed two or more cartridge-cases each of these
being connected with the receiver by means of tubes starting from the lower
extremity of the cases and projecting through the side of the water-tank.
From the upper covers of the cartridge-cases branch tubes run into a hori-
zontal pipe which, in its turn, by means of a bent pipe carried through the
bottom of the water-tank, is in connection with the upper part of the gasometer.
In this gasometer is further arranged another pipe which is carried through
the side of the water-tank and from which lead the consumption or distributing
pipes.
The horizontal pipe has a regulator of known construction by means of which
the connection between this pipe and the upper part of the gasometer is
automatically established and cut off whenever the gasometer is either almost
emptied of or filled with gas.
The apparatus works in the following manner:
It is assumed that the water-tank contains water and one of the cartridge-
cases contains calcium carbide.
When the cock on the branch tube which connects the cartridge-case with the
horizontal pipe and the cock placed upon the tube leading from the lower
end of the cartridge-case, are opened, the water from the water-tank rises into
the cartridge-case, and the generation of gas commences. The gas passes through
the horizontal and bent pipes to the gasometer, causing this to rise. When
the gasometer has almost reached its uppermost position the regulator auto-
matically closes the last named pipes and the gas not being able to pass any
longer this way finds an outlet through the pipe leading from the lower end of
the cartridge case. The water in the cartridge-case is thereby forced out and
back into the receiver, and the generation of gas will gradually decrease until
it stops, while the gas generated during this period passes through the said
lower pipe into the receiver and rises through the water into the gasometer.
The water from the cartridge-cases and which has been in contact with the
carbide, runs, as will be seen, into the receiver, the height of which is regulated
in such a manner that the lower edge of the gasometer can never rise above
the upper edge of the receiver so that the water which has a very offensive

page_text: smell, will always remain under the gasometer and not foul the air in the room
in which the apparatus is placed.
Gradually as the generated gas is consumed the gasometer will sink down until
the regulator, a little before the gasometer reaches its lowermost position, again
automatically opens the passage through the horizontal and bent pipes, so that
the water from the water-tank can again rise into the cartridge-case, whereby
the generation of gas re-commences. The cases are used, one after the other,
gradually as the carbide is consumed.
The cases are made of tin with conical tops and bottoms ending in cylindrical
necks. The upper neck is closed by a cover having a circular groove in which is
arranged an india-rubber packing ring. A strengthening ring, rigidly fixed
around the neck, presses up against the elastic packing-ring when the cover is
closed down. The cover is fastened by means of a clamp the ends of which
catch under the lower edge of the strengthening ring and which is provided with
a set-screw the point of which presses against the top of the cover.
The cartridge-cases are provided at the lower end with an elbow which is
fastened to the elbow of the lower pipe by means of a clamp or ring provided
with a clamping screw.
When the cartridge cases are to be put in place the lower end is first made
fast by means of its clamping screw; the cover is then fastened on by screwing
home its set-screw.
Inside the cartridge-cases are arranged a suitable number of screens shaped
like truncated cones, arranged one above the other with the broadest end down-
ward. The screens are perforated at the top with holes and are on the inside
provided with grooves. The holes give passage to the water, and the grooves
serve to collect the lime-powder produced during the generation of gas. In the
lower conical part of the cases the conical rings are replaced by cylindrical
rings. All the rings serve, besides the purpose stated, as supports for the re-
movable carbide cartridge, which is a perforated cylinder of tin that can be
inserted into the said rings. At the top the cartridge is provided with a handle
and its lower end is shaped like a cone which rests upon the upper edge of the
cylindrical rings in the lower end of the cartridge-case.
When the carbide of a cartridge is used up, the case can easily be removed, as
described above, the cartridge taken out, cleaned and refilled with carbide.
The bad smelling water from the receiver can be drawn off through a pipe.

An Improved Apparatus for Generating Acetylene-gas.
1, SÖREN CHRISTIAN SORENSEN, of 34, Klostergade Aarhus, in the Kingdom
of Denmark, Gas-fitter and Master Turn-cock, 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:-
1
My invention relates to an improved apparatus for generating acetylene-gas
in which the calcium carbide is placed in special cases which I term cartridge-
cases, fastened outside the apparatus and easily removable.
The invention is illustrated in the accompanying drawing in which-
Figure 1 is a vertical section through the gas generating apparatus on the
line A-B of Figure 2:

page_text: Figure 2 is a horizontal section on a smaller scale on the line C-D of
Figure 1:
Figure 3 is a similar section on the line E-F of Figure 1:
Figure 4 is a section through a cartridge-case; and
Figure 5 is a side elevation of a cartridge-case.
My apparatus as is the case with other similar apparatus comprises a water-
tank a in which is inserted a bell-shaped gasometer 6, closed at the top, in such a
way that it may move up and down, it being guided in a suitable manner.
On the bottom of the tank is placed a receiver e, open at the top.
Outside the water-tank are placed two or more cartridge-cases d, each of these
being connected with the receiver e by means of tubes f starting from the
lower extremity of the cases d and projecting through the side of the water-
tank .
From the upper covers of the cartridge-cases tubes run into a pipe which, in
its turn, by means of a bent pipe h carried through the bottom of the water-
tank, is in connection with the upper part of the gasometer. In this gasometer
is further arranged another pipe which is carried through the side of the
water-tank and from which lead the consumption or distributing pipes.
The pipe g has a regulator k of known construction by means of which the
connection between the pipe g and the upper part of the gasometer is auto-
matically established and cut off whenever the gasometer is either almost
emptied of, or filled with, gas.
The apparatus works in the following manner:
It is assumed that the water-tank contains water and one of the cartridge-cases
contains calcium carbide.
When the cock 1, placed upon the pipe which connects the cartridge-case with
the pipe 9, and the cock m, placed upon the pipe leading
from the cartridge case, are opened, the water from the water-
tank rises into the cartridge-case, and the generation of gas commences. The
gas passes through the pipes and to the gasometer causing this to rise.
When the gasometer has almost reached its uppermost position the regulator k
automatically closes the pipes g, h and the gas not being able to pass any
longer this way finds an outlet through the pipe f. The water in the cartridge-
case is thereby forced out and back into the receiver e, and the generation of gas
will gradually decrease until it stops, while the gas generated during this period
passes through the pipe f into the receiver e and rises through the water into
the gasometer b.
The water from the cartridge-cases and which has been in contact with the
carbide, runs, as will be seen, into the cylinder e, the height of which is regulated
in such a manner that the lower edge of the gasometer can never rise above the
upper edge of the receiver e so that the water which has a very offensive smell,
will always remain under the gasometer b and not foul the air in the room
in which the apparatus is placed.
Gradually as the generated gas is consumed the gasometer will sink down
until the regulator k, a little before the gasometer reaches its lowermost position,
again automatically opens the passage through the pipes g, h so that the water
from the water-tank can again rise into the cartridge-case, whereby the genera-
tion of gas re-commences. The cases are used, one after the other, gradually
as the carbide is consumed.
The cases are made of tin with conical tops and bottoms ending in cylin-
drical necks. The upper neck is closed by a cover a having a circular groove in
which is arranged an india-rubber packing ring. A strengthening ring p, rigidly
fixed around the neck, presses up against the elastic packing-ring o when the
cover is closed down. The cover n is fastened by means of a clamp 7 the ends
of which catch under the lower edge of the ring p and which is provided with
a set-screw the point of which presses against the top of the cover n.
The cartridge-cases are provided at the lower end with an elbows which is

page_text: fastened to the elbow ₺ of the pipe ƒ by means of a clamp or ring u provided
with a clamping screw .
When the cartridge cases are to be put in place the lower end is first made fast
by means of the screw; the cover is then fastened on by screwing home the
set-screw r.
.:
Inside the cartridge-cases are arranged a suitable number of screens w shaped
like truncated cones, arranged one above the other with the broadest end down-
ward. The screens are perforated at the top with holes and are on the inside pro-
vided with grooves y.
The holes give passage to the water. The grooves y serve
to collect the lime-powder produced during the generation of gas. In the lower
conical part of the cases the conical rings are replaced by cylindrical rings. All
the rings serve, besides the purpose stated, as supports for the removeable carbide
cartridge z, Figure 5, which is a perforated cylinder of tin that can be inserted
into the rings w. At the top the cartridge is provided with a handle and its
lower end is shaped like a cone which rests upon the upper edge of the cylindrical
rings in the lower end of the cartridge-case.
When the carbide of a cartridge is used up, the case can easily be removed, as
described above, the cartridge taken out, cleaned and refilled with carbide.
The bad smelling water from the receiver e can be drawn off through a pipe c.
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. In an apparatus for generating acetylene gas wherein the carbide is placed
in cartridges which can be inserted in cartridge-cases fixed outside upon the
water-tank of the apparatus, the arrangement of water-pipes leading from the
lower ends of the cartridge-cases and opening out into an open receiver e placed
in the water-tank a of the apparatus and inside the gasometer b, the height of
the said receiver e being regulated in such a manner that the lower edge of
the gasometer will never reach above the upper edge of the receiver, substantially
as set forth.
2. A form of construction of the cartridge-cases mentioned in Claim 1, charac-
terized by a tin cylinder d which is provided below with an elbows and above with
a ring which two parts can, by means of screw clamps be pressed tightly
against the elbow of the pipe f, and against the cover on the branch pipe
leading from the pipe g, the said cylinder d being, moreover, provided inside
with conical rings w, placed above one another with the widest end downward
and having holes and grooves y on the inside, the inside diameter of the said
rings w being such that the carbide-cartridge can be inserted in the rings, sub-
stantially as set forth.
