PILLION, of 1 Place Saint Jean, Dijon, France, Merchant and CHARLES BERTOLUS,
of 8 Place Paul Bert, St. Etienne, France Electrician, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to a construction of gasometer or gasholder for
acetylene gas suitable for use in carrying out the hereinafter described method of
producing the said gas for illuminating and other purposes.
According thereto the gasometer or gasholder comprises a fixed vessel or trough
in which is arranged a bell which dips into water in the said vessel in the saine
manner as in an ordinary gasholder. Around the vessel of the gasholder is arranged
an annular receptacle which serves to balance the weight of the bell. The annular
receptacle communicates with the lower part of the gas generator by means of an
india rubber pipe and also at its upper part with the upper portion of the gasholder
by means of another india rubber pipe so that the same pressure will obtain in the
annular receptacle as in the gasholder and gas generator. Another pipe serves to
effect communication between the upper parts of the gas generator and gas holder,
and serves to allow of the gas when generated passing into the gas holder whence it
can be distributed according to requirements. This connecting pipe (hereinafter
called the gas supply pipe) may pass through the bottom of the water vessel and
extend up within the same to the upper part of the bell.
The manner in which the apparatus operates is as follows:-
The gas as it is produced in the gas generator, passes into the gas holder through
the gas supply pipe, and if the production of gas is greater than that required by the
delivery from the gas holder, the bell is raised by the accumulation of gas therein.
The result is a lowering of the annular receptacle and since there is an equal pressure
in the receptacle and the gas generator the water level in the generator will fall and
contact will no longer be maintained between the water and the calcium carbide, and
as a consequence the production of gas will cease. It will be evident that when the
gas is drawn off from the holder for consumption the bell will descend in the water
vessel and the annular receptacle will simultaneously rise, and in consequence of the
manner in which the gas producer, holder and receptacle are connected together,
contact will be remade between the water and the carbide, thereby causing a fresh
generation of acetylene gas. The production of the gas is thus rendered automatic
and depends upon the amount of gas withdrawn from the holder.

page_text: The apparatus further comprises a safety device which comprises a gas exit pipe
which is arranged within and is made slightly shorter than the bell of the gas holder
to which it is fixed and which is provided at a suitable point with a cock, the upper
end of the pipe communicating by means of another pipe with the external
atmosphere. With this arrangement when the production of gas is in excess of the
requirements, any liability of the said excess raising the bell to its full height and
thus becoming a source of danger is avoided owing to the exit pipe provided with the
cock, which is always kept open, serving to moderate or regulate such excess by
allowing the superfluous gas to escape into the external atmosphere, all escape of gas
into the room wherein the gasholder is situated being thus entirely prevented.
must be understood that the pipe in the gas holder dips into the water in the water
vessel so long as there is no excess of gas in the bell, but when the said bell, by
reason of the pressure of the gas contained in the gas holder, rises unduly,
communication is established between the interior of the bell and the outer air by
means of the exit pipe which then no longer dips into the water (it being shorter
than the bell), although the bell itself has its lower portion still dipping into the
said water. By this means all danger is avoided, any excess of gas generated
escaping into the open air.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Generating and Storing Acetylene.
We, EMILE CHESNAY of 21 Boulevard Carnot, Dijon, France, Photographer LOUIS
PILLION, of 1 Place Saint Jean, Dijon, France, Merchant, and CHARLES BERTOLUS,
of 8 Place Paul Bert, St. Etienne, France, Electrician, 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:-
A gasometer or gasholder for acetylene gas according to the present invention
suitable for use in carrying out the hereinafter described method of producing the
said gas for illuminating and other purposes.
The apparatus is shewn in elevation in the annexed drawing. As will be seen the
gasholder comprises a vessel or trough J in which is arranged a bell K which
dips into water in the vessel J in the same manner as in an ordinary gasholder.
Around the vessel J is arranged an annular receptacle F which serves to halance the
weight of the bell to which it is connected by chains K' passing over pulleys J¹ fixed
on the vessel J. The annular receptacle F communicates with the lower part of the
gas generator Q (which is of the kind described in the Specifications of Applications
Nos. 18,992, and 20,090,") by means of an india rubber pipe 0 and also
at its upper part with the upper portion of the gasholder by means of another india
rubber pipe P so that the same pressure will obtain in the annular receptacle F as in
the gasholder and gas generator. Another pipe M serves to effect communication
between the upper parts of the gas generator and gas holder, and serves to allow of
the gas when generated passing into the gas holder whence it can be distributed
according to requirements. This connecting pipe (hereinafter called the gas supply
pipe) may as shewn pass through the bottom of the water vessel and extend up
within the same to the upper part of the bell.
The manner in which the apparatus operates is as follows:-
As the gas is produced in the generator Q, it passes into the gas holder through

page_text: the gas supply pipe M and if the production of gas is greater than that required by
the delivery from the gas holder, the bell is raised by the accumulation of gas
therein. The result is the lowering of the annular receptacle F and since there is an
equal pressure in the receptacle F and the gas generator Q the water level in the
generator will fall and contact will no longer be maintained between the water and
the calcium carbide, and as a consequence the production of gas will cease.
be evident that when the gas is drawn off from the holder for consumption, the bell
will descend in the water vessel J and the annular receptacle F will simultaneously
rise, and in consequence of the manner in which the gas producer, holder and
receptacle are connected together, contact will be remade between the water and the
carbide, thereby causing a fresh generation of acetylene gas. The production of the
gas is thus rendered automatic and depends upon the amount of gas withdrawn from
the holder.
The apparatus further includes a safety device which comprises a gas exit pipe T
arranged within and made slightly shorter than the bell K of the gas holder to which
it is fixed and which is provided at a suitable point with a cock r, the upper end of
the pipe communicating by means of another pipe x with the external atmosphere.
With this arrangement when the production of gas is in excess of the requirements,
any liability of the said excess raising the bell to its full height and thus becoming
a source of danger is avoided owing to the exit pipe t, the cock of which is always
kept open, serving to moderate or regulate such excess by allowing the superfluous
gas to escape into the external atmosphere, all escape of gas into the room wherein
the gas holder is situated being thus entirely prevented. It must be understood
that the pipe T dips into the water in the water vessel J so long as there is no
excess of gas in the bell, but when the said bell, by reason of the pressure of the
gas contained in the gas holder, rises unduly, communication is established between
the interior of the bell and the outer air by means of the pipe T and the former of
which then no longer dips into the water (it being shorter than the bell), although
the bell itself has its lower portion still dipping into the water. By this means all
danger is avoided, any excess of gas generated escaping into the open air.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to he performed we declare that what we
claim is
1. Apparatus for generating and storing gas substantially as shewn in and
described with reference to the annexed drawings.
2. Providing a gas holder with an escape pipe such as T so that excess of pressure
within the holder will not unduly raise the bell, substantially as described.
