Improvements in Apparatus for the Production of Acetylene Gas.
I, VICTOR DAIX, of 72, Rue Louis Blanc, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-
-
The present invention relates to an apparatus for the production of acetylene
gas, and the special object thereof is to improve these apparatus, with a view
to simplify their construction, and to obtain automatically during the consunip-
tion, a supply of gas proportioned to this consumption.
The generator which is the object of the present invention secures a great
compactness in the arrangement by the combination, in one apparatus, of the
gas-generator, the gas-holder and the automatic distributor of feed water.
In the methods of this kind employed hitherto it is difficult, if not impossible,
to obtain a perfect tightness; furthermore the introduction of carburet is only
operated with difficulty and frequently causes the escape of the gas contained in
the gas-holder or the entrance of air therein; there is also much overproduction
and incomplete utilization of the carburet.
With the new apparatus, which will be completely described in the following
specification, these disadvantages are suppressed by the arrangement of the
charge of carburet in a hermetical casing placed at the lower part of the gas-
holder, by the division of this charge of carburet, and by the special arrangement
of the pipe leading the gas from the generator or gasometer and which forms
a hydraulic joint.
The tank of the gasometer is provided at its lower part, with an opening
serving as a passage for the casing or gas-generator, which is located air-tight
in the lower part of the said tank.
The casing is supported at its inner end and is hermetically closed at its outer
end by a plate fixed by means of screw-nuts or any arrangement allowing its
asy removal.
Within said casing is arranged a drawer which is divided by transverse vertical
artitions in several compartments, to receive the carburet baskets of perforated
heet iron.
On the outside of the casing is secured a pipe extending upwardly, said pipe
eing provided at its upper end with a furnel into which falls the feed water
hich flows through the cock of the syphon, the small branch of said syphon
ing immersed in the water of the reservoir communicating with the tank
rough an opening.
Further, the casing has within the gasometer, a pipe extending upwardly from
e top of said casing and provided with holes on its upper end, on which is
aced a cap provided on its lower part, which is beneath the line of the water
said tank, with a centring ring and with openings.
The bell or gas-holder of the gasometer is advisably guided and supports a
fety-pipe. Moreover the gas escapes from said gas-holder through a pipe,
ssing through the water-tank at the lower part thereof
ΓΥ

page_text: on the outside of said tank with a cock, arranged to open or to cut off communica-
tion between said pipe and the supply service for consumption.
The operation of the improved apparatus is as follows:-
When, on account of consumption of gas, the gas holder descends, the syphon
becomes immersed in the reservoir and as the small branch of said syphon is
under the line of the water, this water is free to flow through the cock of said
syphon. This water falls into the funnel of the feeding pipe and through this
pipe on to the carburet contained in the first compartment of the drawer. Then
occurs production of acetylene gas which, passing through the gas pipe and the
holes enters the safety cap, from whence escapes by the holes and is discharged
into the gas-holder, after being deprived of the steam which it contains and
being cooled by passing through the water in said tank.
The production of acetylene gas causes the receiver to rise, carrying with it
the distributing syphon, and as the small bent branch of said syphon is above the
water-line, the flow through the cock ceases.
As the production of gas is less than the consumption, the gas-holder descends
again and with it the syphon which becomes immersed in the reservoir; the flow
of water recommences, a fresh quantity of carburet is attacked and the produced
gas causes the gas-holder to rise again, the flow ceasing as soon as the small
branch of the syphon is above the water-line and so on.
When the carburet in the first basket is consumed and the corresponding com-
partment filled with water, the excess overflows into the second compartment
which now enters into action and so on until the last basket of carburet is con-
sumed and all the compartments of the drawer are filled with water. It will
be then sufficient in order to recharge the apparatus, to pull out the drawer, empty
it and refill it with carburet, after having cleared the baskets of the residuum
they contain.
During the operation of the apparatus, the produced gas cannot escape from
the casing by the feeding pipe as the latter contains in its bent lower part a
certain quantity of water which forms a seal against the escape of the gas.
In the same way, during the charging of the apparatus and the periods of non-
production, the return of the gas contained in the gas-holder towards the casing
is impossible because it would be necessary for said gas to pass through the upper
part of the water, contained in the tank, to enter by the holes of the safety cap
and thence the gas pipe.
With this apparatus the arrangement of the gas generator on the bottom of
said tank of the gasometer has the advantage of preventing any abnormal heat-
ing of the apparatus, the greater quantity of the heat produced by the reaction
being absorbed by the water in the said tank.

Improvements in Apparatus for the Production of Acetylene Gas.
I, VICTOR DAIX, of 72, Rue Louis Blanc, Paris, France, Engineer, 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:-
The present invention relates to an apparatus for the producting of acetylene
gas, and the special object thereof is to improve this apparatus. With a view

to simply their construction, and to obtain automatically during the consump
tion, a supply of gas proportioned to this consumption.
The generator which is the object of the present invention secures a great
compactness in the arrangement by the combination, in one apparatus, of the
gas-generator, the gas-holder and the automatic distributor of feed water.
In the methods of this kind employed hitherto it is difficult, if not impossible,
to obtain a perfect tightness; furthermore the introduction of carburet is only
operated with difficulty and frequently causes the escape of the gas contained in
the gas-holder or the entrance of air therein; there is also much overproduction
O and incomplete utilization of the carburet.
With the new apparatus, which will be completely described in the following
description and specified in the claims, these disadvantages are suppressed by the
arrangement of the charge of carburet in a hermetical casing placed at the lower
part of the gas-holder, by the division of this charge of carburet, and by the
special arrangement of the pipe leading the gas from the generator or gasometer
and which forms a hydraulic joint.
In the annexed drawing is shown, as an example, a vertical section of the
apparatus showing the operation thereof.
A is a water-tank, B a gas holder, C indicates a regulating siphon for the
admission of water, D is the water reservoir of the siphon G communicating with
the water-tank A by the opening .
by a plate b. F is a carburet drawer divided in several transverse compartments
E is a casing forming gas generator closed
formed by vertical walls c, G shows the carburet baskets, I is a pipe leading the
gas into the bell B of the gas-holder and which has openings d, J is a cap
placed on the pipe I and provided with openings e, K is a safety pipe of the
gas-holder, and finally L is an outlet pipe, having a cock M, and communicating
with the conduit of the burners.
The tank A of the gasometer is provided at its lower part, with an opening
serving as a passage from the casing E or gas-generator, which is located air-
tight in the lower part of the said tank A.
The casing E is supported at its inner end by the part f and is hermetically
closed at its outer end by the plate fixed by means of screw-nuts or any arrange-
ment allowing its easy removal.
Within said casing E is arranged the drawer F which is divided by transverse
vertical walls c, in several compartments, to receive the carburet baskets G of
perforated sheet iron.
On the outside of the casing E is secured the pipe H extending upwardly, said
ipe being provided at its upper end with a funnel into which falls the feed
vater which flows through the cock of the siphon C, the small branch of said
iphon being immersed in the water of the reservoir D communicating with the
ank A through the opening a, and the cock C may be replaced by a simple
djutage.
Further, the casing E has within the gasometer, a pipe I extending upwardly
rom the top of said casing and provided with holes on its upper end, on
hicli is placed a cap J provided on its lower part, which is beneath the line
the water in said tank, with a centring ring and with openings c.
The bell or gas-holder B of the gasometer is advisably guided and supports
e safety-pipe K. Moreover the gas escapes from said gas-holder through the
pe L said pipe passing through the water-tank A at the lower part thereof and
ing provided on the outside of said tank with a cock M, arranged to open or
cut off communication between the pipe L and the supply service for con-
mption.
The operation of the improved apparatus is as follows:-
When, on account of consumption of gas, the gas holder B descends, the syphon
comes immersed in the reservoir D and as the small branch of said syphon C
under the line of the water, this water is free to flow through the cool

page_text: said syphon. This water falls into the funnel of the pipe H and through this
pipe on to the carburet contained in the first compartment of the drawer F
Then occurs production of acetylene gas which passing through the pipe I and
the holes enters the cap J, from whence it escapes by the holes e and is dis-
charged into the gas-holder B, after being deprived of the steam which it contains
and being cooled by passing through the water in said tank.
The production of acetylene gas causes the receiver B to rise; carrying with
it the distributing syphon, and as the small bent branch of said syphon is above
the water-line, the flow through the cock ceases.
As the production of gas is less than the consumption, the gas-holder descends
again and with it the syphon which becomes immersed in the reservoir D; the
flow of water recommences; a fresh quantity of carburet is attacked and the pro-
duced gas causes the gas holder to rise again, the flow ceasing as soon as the small
branch of the siphon is above the water-line and so on.
When the carburet in the first basket is consumed and the corresponding
compartment filled with water, the excess overflows into the second compartment
which now enters into action and so on until the last basket of carburet is con-
sumed and all the compartments of the drawer F are filled with water. It will
be then sufficient, in order to recharge the apparatus, to remove the plate b
pull out the drawer E, empty it and refill it with carburet, after having cleared
the baskets of the residuum they contain.
During the operation of the apparatus, the produced gas cannot escape from
the casing by the pipe H as the latter contains in its bent lower part a certain
quantity of water which forms a seal against the escape of the gas.
In the same way, during the charging of the apparatus and the periods of non-
production, the return of the gas contained in the gas-holder B towards the
casing E is impossible because it would be necessary for said gas to pass through
the upper part of the water contained in the tank, to enter by the holes e the
cap D and thence the pipe I.
With this apparatus the arrangement of the gas-generator on the bottom of
said tank of the gasometer has the advantage of preventing any abnormal heating
of the apparatus, the greater quantity of the heat produced by the reaction being
absorbed by the water in the said tank.
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 the automatic production of acetylene gas, comprising a
gasometer and an automatical distributor of feed water, the combination of a
gas generator arranged air-tight on the bottom of the water-tank of the gasometer
and formed of an external envelope hermetically closed by a door, arranged on the
outside of said water-tank, a drawer placed in the external envelope and divided
into several compartments by transverse vertical partitions, carbide baskets of
perforated sheet iron placed in the compartments of the drawer, to be successively
used, and means for leading the water from the gasometer to the gas generator,
conducting the gas from the gas-generator into the gas-holder and preventing
its return to said gas generator, substantially as and for the purpose set forth.
2) In an apparatus for automatic production of acetylene gas comprising a
gasometer and an automatic distributor of feed water, the combination of a gas
generator located within the water-tank of said gasometer, a feed pipe discharging
into said gas generator and leading there the water taken alternately from said
water-tank of the gasometer by a siphon worked by the gas-holder or bell of
said gasometer, and means for conducting the gas from the gas-generator into said
gas-holder and prevent its return into said gas-generator, substantially as and
for the purpose set forth.
3) In an apparatus for automatic production of acetylene gas comprising a
gasometer and an automatic distributor of feed-water, the combination of a gas-

page_text: generator located within the water-tank of said gasometer, a pipe perforated with
side openings near its upper end, and leading the gas from the gas-generator
into the gas-holder, a cap forming a hydraulic-joint on the orifice of said tube to
prevent the return of the gas to said gas-generator, and means for leading the
water from the gasometer into the generator, substantially as and for the purpose
set forth.
