Improvements in Apparatus for Generating, Storing, and Delivering
Acetylene Gas.
We, EMILE CHESNAY of 21 Boulevard Carnot, Dijon, France, Photographer
and LOUIS PILLION of 1 Place Saint Jean, Dijon, France, Manufacturer do
hereby declare the nature of this invention to be as follows:-
This invention relates to an apparatus for the production storage and delivery
of acetylene gas and comprises:
1. The gas generator.
2. The gasomoter or holder.
3. An automatic arrangement or device designed to produce, increase, diminish
or arrest the action of the water upon the carbide employed.
1. The generator comprises (1) a cylinder or other vessel of suitable shape
pierced with holes and formed of one continuous piece of material or it may be
built up or composed of bars or pieces of materials arranged in various ways and
directions or of a network of material.
This cylinder is closed at its upper end by means of a cover opening outwardly
and which may be kept closed by means of a turn button. To facilitate the escape
of the gos the cover should also be pierced with several holes. The lower end of
the cylinder is entirely open.
2. A series of small metallic rods branching from a central rod, thereby forming
an enlargement said branches extending substantially across the internal diameter.
of the cylinder after the manner of a piston. Instead of rods, metallic plates,
strips, threads or wires arranged in different ways may be employed.
3. A receiver adapted to open at its upper end to admit the introduction of the
apparatus above. described. This opening has a cover by which it can be
bermetically closed. At the base of the receiver a siphon is arranged to which is
connected a flexible pipe for the purpose hereinafter described. The syphon is for
the purpose of maintaining a sufficient water seal or trap and also to prevent the
residual products of the reaction from choking the communication pipe between
the receiver and a hydraulic counter weight. The receiver is so constructed as to
allow the aforesaid cylinder to fit and slide therein with moderate friction or
otherwise suitably guided.
11. The gasholder comprises :-
1. A well or trough,
2. A bell.

page_text: III. An automatic arrangement or device, which acts as a counter-weight to the
gasholder, and consists of a receiver containing water and communicating with the
generator by means of a flexible pipe. The method of using the apparatus is as
follows:-The perforated or built-up cylinder or vessel is closed at its base by
means of a drop or lozenge of sugar or any other rigid substance soluble in water
and of suitable shape adapted to close the aperture, and then filled with pieces of
carbide after which it is closed by means of the cover situate at its upper end.
This cylinder is now introduced into the receiver, in which has been previously
placed the iron tod with enlarged portion forming a stationary piston, until
contact takes place between the surface of said piston and the lozenge closing
the lower end of the cylinder. The receiver is then hermetically closed by means
of its cover.
Water is poured into the automatic device until passing through the flexible
pipe it enters the generator and reaches the level of the soluble lozenge the
recoiver being situate meantime on the ground level. The counter-weighting
receiver is now lifted by hand to a height of say about 30 metres. The result of
the movement being to raise the level of the water contained in the generator as
soon as the lozenge with which it is in contact dissolves. The carbide is attacked;
the points of the surface of the piston assisting the action by disintegrating the
carbide facilitating the dilution of the residues of the reaction. Acetylene gas is
now generated and passes to the bell of the gasometer which rises; in consequence
the counterweight simultaneously descending thereby stopping the action of the
water on the carbide by sufficiently lowering the level of that liquid. When the
gas is being discharged, the gasometer descends, and causes the counterweight to
rise, whereby the carbide is again attacked by the water according to the extent of
the discharge.
Improvements in Apparatus for Generating, Storing, and Delivering
Acetylene Gas.
We, EMILE CHESNAY of 21 Boulevard Carnot, Dijon, France, and LOUIS
PILLION, of Place Saint Jean, Dijon, France, 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 an apparatus for the production storage and delivery of
acetylene gas, comprising :-
1. A gas generator.
2. A gasometer or holder aud
3. Au automatic arrangement or device designed to produce, increase, diminish
or arrest the action of the water upon the carbide employed.
The accompanying drawings illustrate apparatus according to our invention
Fig. 1 being an elevation partly in section of the complete apparatus the gas
holder being in its raised position.
Fig. 2 a similar view but showing the gas holder in its lowered position, and
Fig. 3 detail views hereinafter more particularly referred to.

The automatic arrangement or device C which acts as a counter-weight to the
gas-holder, consists of a receiver containing water and communicating with the
generator by means of the flexible pipe I. The method of using the apparatus is
as follows: The perforated or built up cylinder or vessel D or D' is closed at its
base by means of a drop or lozenge of sugar or any other rigid substance soluble
in water and of suitable shape adapted to close the aperture, and then filled with
pieces of carbide, after which it is closed by means of the cover D* at its upper
end. The cylinder is now introduced into the receiver F, in which has been
previously placed the iron rod E with enlarged portion forming a stationary piston,
until contact takes place between the surfaco of said piston and the lozengo closing
the lower end of the cylinder. The receiver F is then hermetically closed by
means of the cover G.
Water is now poured into the automatic device C until passing through the
flexible pipe I it enters the generator and reaches the level of the soluble lozenge,
the receiver F being situate meantime on the ground level. The counter-weighting
receiver C is now lifted by hand to a height of say about 0.30 metres, the result of
the movement being to raise the level of the water contained in the generator to such
an extent that it will come in contact with the lozenge at the lower part of D.
As soon as the lozenge is dissolved the water attacks the carbide; the points of
the surface of the piston assisting the action by disintegrating the carbide
facilitating the dilution of the residues of the reaction. Acetylene gas is now
generated and passes to the bell of the gasometer which rises; in cousequence the
counterweight simultaneously desconding thereby stopping the action of the water
on the carbide by sufficiently lowering the level of that liquid. When the gas is
being discharged, the gasometer descends, and causes the counterweight to rise,
whereby the carbide is again attacked by the water according to the extent of
the discharge.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the saine is to be performed we declare that what we
claim is :-
1. Our improved apparatus for generating storing and delivering acetylene
gas substantially as shewn in and described with reference to the accompanying
drawings.
2. In apparatus of the kind referred to in the preceding claim a gas generator
comprising a carbide receptacle open at its lower end and formed or provided
with openings or spaces through which gas can pass, in combination with a fixed
piston formed of rods or the like, both the carbide receptacle and the piston and its
stem being enclosed within a receiver and the arrangement being such that the
carbide receptacle will descend as the carbide within it is converted into gas
substantially as described.
