Improvements in Apparatus for Making Acetylene Gas.
I, AUGUST DAUBER, of Bochum, Westfalia, Germany, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved apparatus for producing gas of acetylene
from calcum carbides and other suitable raw materials.
The new apparatus is provided with a gasholder containing a device by means
of which the production of gas is regulated according to the consumption and in
a surplus amount of water so that no heating can take place and that every
danger is excluded. The feeding mechanism is so arranged that gas produced
in the same can escape into the main gasholder or elsewhere and that the raw
material is admitted into the apparatus only in the middle of the tank so that no
gas can escape at the sides while the used out carbide can be drawn off without
interfering with the working of the apparatus. I attain these results by the
apparatus shown on the accompanying drawing in which:
Fig. 1 is a vertical central section along line I-I of Fig. 2:
Fig. 2 is a horizontal section along line II-II of Fig. 1;
Fig. 3 is a vertical section along the broken line III-III of Fig. 2.
The gasholder consists as usually in such apparatus of a fixed tank A and a
bell or movable top B; a waterpipe C having a float C regulates the admission
of water and keeps it at an uniform level; a discharge pipe D allows the escape
of the gas.
Suitable guides are provided so that the upper or movable part of the gas-
holder can conveniently move up and down in the lower one in a telescopelike
manner.
The feeding arrangement for admitting new raw-material into the central part
of the tank A is constructed as follows: A large tube E is fixed to the roof of the
bell B and hangs down into the latter; at the bottom it is closed and at the top
it is provided with a feeding hopper F, which is covered by a lid G and closed
below by a cone H, the latter can be raised and lowered so as to open or close the
communication from the hopper F to the lower part of the tube E. In the
center of this tube is arranged a perforated pipe J, the object of which will
be explained hereafter; a helix K is arranged between the pipe J and the sides
of the tube E, down upon which any rawmaterial entering into the tube E from
the hopper is guided to an opening L at the bottom of the tube.
The lower part of the tube E is guided in a fixed tube M standing upon an
oblique plate N carried on a girder O and an angle iron 01 at the bottom part
of the tank A. About half way up, in the middle height of the tank A a spout
or a funnel P is arranged in the tube M, forming an outlet sideways, and it
will be easily understood from the drawing that, when the bell B with the
feeding tube E has sunk so deep into the tank, that the side opening L in the
tube E arrives at the upper edge 1" of the funnel P and lower, the discharge of
the material upon the helix K in the tube E into the funnel P begins. In order

the opening into the funnel begins a fixed ring Q is arranged in the tube M.
The funnel P discharges its contents into a small tank V placed upon the
oblique plate N and reaching up to the water level in the apparatus. This has
for its object to prevent the distribution of the raw material over the whole area
of the bottom of the tank and that no formation of gas can take place near the
edges, where it could escape between the sides of the tank A and the bell B.
The lower front edge of the small tank V has an opening through which the
macerated material can get out of the small tank and get at the outlet cock W.
If there is any formation of gas going on in the tube E or other vapours formed
therein they can be let out through the perforated pipe J, which out side of the
hopper F by a tube X leads the gas back into the gasholder or which may con-
duct it to some other place for further destination.
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 acetylene gas producer a tank A in combination with a bell B work-
ing up and down in the tank, a filling tube E fixed to the cover of said bell, a
feeding hopper F fixed on the top of the filling tube and a helix K placed inside
of said tube E around a perforated tube J in the center of the tube E and leading
material put thereon to an opening L at the foot of said tube, the whole as
described and illustrated and for the purpose set forth.
2. In a gas producer, in combination with a tank A a small tank placed
inside of said tank upon an inclined plate N and a fixed tube M standing upon
said plate behind the small tank N, a funnel P, arranged at a certain height
of said tube M, the upper part of this tube surrounding the filling tube E and
guiding it, the whole as described and illustrated and for the purpose set forth.
