page_text: Improvements in Acetylene Gas Generators,
I, HEINRICH DANT, of No. 6, Tolgerstrasse, Nuremberg, in the Kingdom of Bavaria,
and Empire of Germany, Fitter, 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 improvements in apparatus or plant for generating
acetylene gas, the object being by the peculiar construction and arrangement of the
cells containing the calcium carbide, to ensure the contents of each one in succession
being converted into gas, and again successively recharged when the carbide is
completely consumed and without causing any disorganization in the operations of
the apparatus.
Such being the nature and object of my said invention, the following is a complete
description of same, reference being had to the accompanying drawing which is a
vertical sectional view of the improved apparatus.
In
According to this invention I employ a reservoir 1 arranged in and fastened to the
bottom of the cistern 3 and closed at the top by a cap 4, the lower part being
provided with holes 2 allowing water to pass to the interior from the cistern 3.
the cap 4 are a series of airtight cylinders 5 which contain the calcium carbide
vessels 6. The said cylinders 5 are furnished with cocks 7 serving for water inlet and
gas outlet, and each one differs from the others in that they are at various heights
or points above the water level, so that by this arrangement one cylinder comes in
operation at the time when the other lower lying one has been flooded and has
finished its operation, i.e., all its carbide is converted into gas and is submerged.
In the middle of the cap 4 is a cleaner or cooler 82 communicating with the
reservoir 1 by a syphon tube 8, said cleaner or cooler 8* having two cocks 9 and 10,
of which the former serves for the water outlet, and the latter for controlling the
level of the water in the cleaner.
When the apparatus is not in operation, the vessel 3 is filled with water up to the
cock 11, the carbide cells are charged, and the cylinders 5 closed and the cocks 7
opened. Water is now allowed to pass in until all the carbide cylinders 5 are
submerged and the pressure drives the water into the lowest lying cylinder through
its cock, and gas is generated. When the development of gas is proceeding the gas
forces the water through the cock and into the reservoir 1 whence it is forced
When the contents of the first
through the tube 8 into the cleaner or cooler 8*.
cylinder are completely converted into gas, it is filled with water by the water
compressure in the cistern 3, and after this the water ascends to the cock of the
cylinder lying next higher than the first one, in order to cause the generation of
gas in it, and so on to the last cylinder. When the carbide in the cylinders is to be
renewed the cocks 7 must be closed and the cylinder can be filled with new carbide
without any disorganization of the operation of the apparatus.

invention, and in what manner the same is to be performed, I declare that what I
claim is
The general construction, arrangement, and combination of parts constituting the
improved acetylene gas generator as herein described and substantially as illustrated
by the annexed drawing.
