Improvements in and connected with Apparatus for the Generation
and Combustion of Acetylene Gas..
We, JULES ALBERT AGERON, of 48, Rue du General Foy, and LOUIS PHILIPPE
WIRTH, of 22 and 24, Avenue Philippe-Auguste, both in Paris, in the Republic
of France, Engineers, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in and connected with apparatus for the
generation and combustion of acetylene gas chiefly designed for illuminating
purposes and wherein the said gas which is rich in carbon is caused to burn by
means of burners of novel construction in an artificial oxidizing atmosphere so as
to give to the flame a high illuminating power.
"
According to our invention we generate the acetylene gas by the decomposition
of carbide of calcium which falls into water contained in apparatus of novel
construction or acetylogenes" and we regulate its pressure when necessary in
a very efficient manner by causing it to pass into an automatic regulating apparatus,
hereinafter described, before conveying it away for consumption. The acetylene
gas then passes into burners in which its flame is constantly surrounded by an
oxidizing layer or zone formed by the impingement below or into the flame of a
jet or current of oxygen or ozone or of a mixture of these gases with air. Our
arrangement can be employed for illumination of all kinds from the simple light-
ing of rooms to the powerful illumination required for the lanterns of search-
lights, light-houses, etc.
A suitable construction of our apparatus or "acetylogene" comprises a vessel
formed conical or funnel-shaped at its lower end and resting upon feet and having
arranged upon its upper end the carbide holder with its distributer and a gasometer,
the said vessel being also at its lower part in communication with a closed receiver
for the reception of residues, deposits, etc.
The vessel is almost entirely filled with water so that the carbide, which in the
form of powder falls into this large mass of water in quantity according to require-
ment, is decomposed without at all heating the apparatus. The lime formed falls
to the lower part of the vessel and into the receiver; when the latter is full a
cock fitted between the vessel and the said receiver is closed, the latter is removed
and emptied, then filled with water and replaced, after which the cock is again
opened.
A
The carbide holder comprises a closed vessel conical or funnel-shaped at its
lower end and bolted upon a cylinder riveted to the water containing vessel.
register valve controls the feeding of the carbide into the funnel. The spindle
carrying the rotary disc of the valve is operated from the exterior by means of a
handle arranged above the filling plug of the carbide holder in such a manner that
it is necessary to close the valve when it is desired to recharge the carbide holder.
The spindle has keyed upon it scrapers for detaching any carbide which may

page_text: adhere to the walls of the funnel. The funnel is circular in section and its outlet
orifice is closed by a plate on a weighted pivoted lever. The bell or sliding
cylinder of the gasometer or gas-holder presses through the medium of a rod and
a roller upon the longer arm of this lever and a counterweight is arranged upon
the smaller arm thereof. When the bell or sliding cylinder is in its upper position
the longer arm is maintained horizontal by the counterweight and the rectangular
plate or plug on the lever closes the circular orifice of the funnel. If the consump-
tion of gas becomes greater than the production the sliding cylinder falls and
swings the lever upon its pivot so as to gradually open the outlet orifice for the
carbide. There thus always drops into the water in the vessel a quantity of
carbide proportional to requirement. This arrangement forms a very efficient
regulator. A removable window enables the regulator to be frequently examined
so as to ensure that it is in working order.
The gasometer or gas-holder comprises an outer vessel or cylinder and an inner
water containing vessel both fixed upon the upper end of the main water vessel.
The cylinder open at its two ends and to it are secured arms or collars carrying
rollers for guiding the rod for operating the weighted lever, and the bell or sliding
cylinder in its up and down movements.
The apparatus is provided with a safety valve consisting of two tubes which slide
one within the other and are guided by guide rollers, an annular space being left
between the said two tubes: one tube being fixed to the sliding cylinder and the
other to the main water vessel, the latter of the two tubes also being open to the at-
mosphere. If the pressure of gas from any exceptional cause should exceed the
maximum predetermined pressure, the lower end of the tube fixed to the sliding
cylinder would leave the water in the main vessel and the gas would escape through
the other of the two tubes.
A
In the case where it is desired to obtain gas at a high pressure, the above
described gasometer is replaced by a metal bellows fixed at its lower end upon the
main vessel. This bellows is formed of sheet metal rings connected in pairs around
their peripheries. A central rod fixed above the bellows is guided at its lower end.
A suitable form of portable apparatus constructed according to our invention
comprises a cylindrical vessel the lower part, which forms the gas generator, being
full of water up to the level of a cock and the upper part, which is-connected with
and fixed to the first part, forming the gasometer and the carbide holder.
sliding cylinder or bell annular in cross section slides in an outer jacket or vessel
and the carbide holder which is fixed at its lower end around its periphery to the
upper part of the gas generator is arranged in the centrai space of the said sliding
cylinder or bell. The carbide holder is provided with a funnel the outlet orifice
of which is closed by a wheel fixed upon an oscillating lever the pivot of which
also serves as the centre of the wheel and of the outlet orifice of the funnel. Upon
one of the arms of the lever the bell of the gasometer acts through the medium of
a rod and to the other arm thereof we pivot a rod provided with a counterweight.
The wheel is provided with a recess which allows carbide to fall in quantities
increasing as the sliding cylinder of the gasometer falls in its outer cylinder.
The carbide is distributed by a register valve similar to that herein before
described and operated by a rod which is also provided with a scraper.
For emptying the apparatus we form the bottom of the gas generator inclined
and we arrange the emptying hole at the lowest point in this inclined portion of
the gas generator. The lime is by this means easily removed.
In the double bottom of the gas generator there is a layer of water into which
the acetylene gas can bubble being drawn from the upper part of the apparatus
and escaping by a tube connected with the tube conveying the gas to the cou-
sumption apparatus.
For illuminating purposes we utilize burners in which the flame from the acety-
lene gas burns in an oxidizing atmosphere whereby the complete combustion of
the carbide is ensured and the flame is rendered more brilliant and powerful.
A simple burner comprises a tube in the form of a crescent and fitted to the supply

page_text: another.
pipe for the acetylene gas. The said gas escapes by two converging orifices formed
in two steatite blocks. The two jets of gas are broken or pulverized against one
A vertical tube opens below this flame, the said tube being provided
with a gauze cover and communicating with a reservoir of oxidizing and com-
bustible gas such as oxygen or ozone. This tube provided with a sleeve which
is held in place by friction, perforated with holes for the passage of air and provided
with a gauze plug or cover. The oxygen which flows into the central tube creates
a draught of air and forms with this air a mixture which immediately surrounds
the flame so that the acetylene gas burns in the said mixture.
To form luminous foci with round or polygonal flames for the lanterns of search-
lights, light-houses, etc. we employ an arrangement wherein the acetylene gas flows
in through a central tube into branches. The jets issuing through orifices from
the branches cut one another at a constant angle and form a round or polygonal
flame. Below these jets there are arranged vertical tubes which branch from a
ring into which the oxidizing gas, namely, oxygen or ozone flows.
In another construction of burner the oxygen also flows through two convergent
passages arranged parallel to the passages through which the acetylene gas
flows.
In the case of lanterns we advantageously provide a reflector at the focus of which
the burner is placed and a suitable lens. A chimney enables a draught to be
obtained and a second chimney or jacket covers the reflector.
In the case of a street-lamp the acetylene gas is provided from a cylinder in
which it is compressed and the oxygen from a similar cylinder, the two cylinders
being arranged in the foot of the lamp. Above each cylinder we arrange an
automatic pressure regulator consisting of a bellows the upper end of which is fixed
and the lower end of which is movable and hinged to the end of a lever keyed
upon the plug of a cock which controls the flow of acetylene into the bellows.
A counterweight maintains the bellows closed and the cock opened when the
apparatus is at rest. The acetylene gas or the oxygen flows through the cock and
into the bellows which expands more or less until the pressure equilibrates the
counterweight. The gas therefore always flows from the bellows at a constant
pressure.
It will be obvious that our apparatus for the production of acetylene gas can
be employed in all cases where this gas is used for illuminating or for heating
purposes and for fluid motors.

Improvements in and connected with Apparatus for the Generation
and Combustion of Acetylene Gas.
We, JULES ALBERT AGERON, of 48, Rue du General Foy, and LOUIS PHILIPPE
WIRTH, of 22 and 24, Avenue Philippe-Auguste, both in Paris, in the Republic
of France, Engineers, 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:-
Our invention relates to improvements in and connected with apparatus for the
generation and combustion of acetylene gas chiefly designed for illuminating
purposes and wherein the said gas which is rich in carbon is caused to burn by

page_text: -
means of burners of novel construction in an artificial oxidizing atmosphere so
as to give to the flame an illuminating power similar to that of an electric arc
lamp and the intensity of which can be varied as required.
According to our invention we generate the acetylene gas by the decomposition
of carbide of calcium which falls into water contained in apparatus of novel con-
struction which we term 66
acetylogenes" and we regulate its pressure when
necessary in a very efficient manner by causing it to pass into an automatic regulat-
ing apparatus, hereinafter described, before conveying it away for consumption.
The acetylene gas then passes into burners of novel construction in which its flame
is constantly surrounded by an oxidizing layer or zone formed by the impingement
below or into the flame of a jet or current of oxygen or ozone or of a mixture of
these gases with air. Our arrangement can be employed for illumination of all
kinds from the simple lighting of rooms to the powerful illumination required for
the lanterns of search-lights, light-houses, etc.
In the accompanying drawings we have represented the various apparatuses
employed in our installations.

Figure 15 is a vertical section of a street lamp arranged to use compressed

Figure 16 is a section shewing our automatic gas regulator.
Referring to Figures 1 to 5 our apparatus or acetylogene" comprises a gas
generator or vessel A formed conical or funnel-shaped at its lower end and resting
upon feet D and having arranged upon its upper end the carbide holder with its
distributer and a gasometer the said vessel being also at its lower part in communi-
cation with a closed receiver C for the reception of residues, deposits, etc.
The vessel is almost entirely filled with water and the receiver C is also filled
with water.
A cock D placed horizontally between the vessel A and the receiver C and
operated by means of a hand-wheel D², allows of closing communication between
these two vessels when the receiver C is full of lime and it is necessary to remove it
in order to empty it. Before replacing the receiver it is filled with water and when
the cock D is opened the said water will mingle with that of the vessel A and
become, in turn, rapidly saturated with gas.
The carbide holder comprises a closed vessel E conical or funnel-shaped at its
lower end bolted upon a cylinder F riveted to the water containing vessel A. A
register valve M, N controls the feeding of the carbide into the funnel or hopper.
This register valve is composed of two overlaying discs or plates both provided with
identical radial openings. One of these discs is stationary and the other is movable
round its axis, so that the openings of the two discs can be brought into position
immediately above one another and allow the carbide to fall, or the full portions

page_text: of the movable disc can be brought above the openings of the stationary disc so
as to stop the falling of the carbide. The spindle P carrying the rotary disc of
the valve is operated from the exterior by means of a handle PI arranged above the
filling plug of the carbide holder in such a manner that it is necessary to close
the valve when it is desired to recharge the carbide holder. Escape of gas is thus
prevented. The spindle P has keyed upon it scrapers R and R' for detaching any
carbide which may adhere to the walls of the funnel or hopper. The funnel E
is circular in section and its outlet orifice is closed by a plate on a lever G pivoted
at O on the sides of the funnel. The bell or sliding cylinder I of the gasometer
or gas-holder presses through the medium of a rod J and a roller J¹ upon the
longer arm of this lever and a counterweight H is arranged upon the smaller arm
thereof. When the bell or sliding cylinder I is in its upper position the longer
arm G2 is maintained horizontal by the counterweight H and the rectangular plate
or plug G¹ on the lever closes the circular orifice of the funnel. If the consumption
of gas becomes greater than the production the sliding cylinder I falls and swings
the lever upon its pivot O so as to gradually open the outlet orifice for the carbide.
There, thus, always drops into the water in the vessel a quantity of carbide pro-
portional to requirement. This arrangement forms at once a very efficient dis-
tributer and regulator. A removable window S enables the regulator to be
frequently examined so as to ensure that it is in working order.
In Figures 3bis, 4 bis and 5 bis we have illustrated a modification of the carbide
distributer.
•
On the funnel or hopper E and within the cylinder F is pivoted at o a movable
box a
guided by its upper spherical wall. In the box a is fixed a cross-piece b
having thinned edges which is adapted to exactly close the lower aperture of the
funnel E when the box a moves upon its pivots o. The lower opening of the box
is itself closed when the apparatus is at rest by a fixed plug or stopper c having
thinned edges suspended and fixed to the cover of the cylinder F by two parallel
tubes a, d which embrace the box a and by the connecting pieces i, d¹.. When
the aperture of the funnel is open the carbide falls into the box a but cannot fall
into the gas generator because the box is at this moment closed by the stopper or
shutter c; on the other hand when the box oscillates and uncovers its lower
aperture, the cross-piece b closes the funnel so that only a quantity of carbide
corresponding to the capacity of the box a can fall at one time into the gas
generator, whereby we prevent any eventual over production which might arise
from the aperture of the funnel remaining open by accident or being wilfully held
open.
To the exterior of the box a are also connected a counterweight f and a horizontal
arm on which the bell or sliding cylinder I constantly bears through the medium
of its central guiding rod J and of the roller J¹.
When the bell I is in its uppermost position, the arm g is kept horizontal by the
counterweight f and the box a has its aperture above the plug or stopper c.
When the apparatus is started, the bell I is brought to its uppermost position
and kept lifted during a certain time. At this moment the funnel E is open and
the box a is closed by the plug c; consequently if the register valve is opened, the
box a gets filled with carbide and if the bell I be then released it will bear heavily
on the arm g and force the box a to swing; as the aperture of the latter moves
away, the carbide falls into the vessel A, but only the amount contained in said
box a can fall, because when the aperture of this box is entirely open, the aperture
of the funnel by which the carbide enters, is closed by the cross-piece b.
The gas produced lifts up the bell I, and the counterweight f forces the box a
to swing in the opposite direction, thus bringing the aperture of this box above
the plug and uncovering the aperture of the funnel; the box becomes refilled
with carbide, but it will only become empty when the gas has been consumed, that
is to say, when the bell I comes back to its lowermost position.
It will be understood that this arrangement prevents any untimely falling of
the carbide into the vessel A, even if the apparatus be maliciously interfered with,

page_text: for example if a rod be introduced into the aperture of the funnel in order to
keep it open when it ought to be closed, it would not matter because the box is
necessarily closed. It will be seen that if by any means the aperture of the box a
is kept away from the plug, only the amount of carbide contained in the box a
will be able to fali, for the funnel is necessarily closed at that time; now, as the
capacity of the box a is adapted for containing only the amount of carbide the
decomposition of which gives a quantity of gas corresponding to the capacity of
the gas-holder bell, no over-production is to be feared.
A carbide feeding device perfectly regulated and preventing over-production is
thus provided.
The gasometer or gas-holder, as will be seen by reference to Figure 3 and
Figure 3b, comprises an outer vessel or cylinder T and an inner water containing
vessel U both fixed upon the upper end of the main water vessel A. The quantity
of water necessary for the hydraulic joint is thus reduced to a minimum. The
cylinder U is open at its two ends and to it are secured arms or collars V, Vi
carrying rollers X, X' for guiding the rod J for operating the weighted lever and
the bell or sliding cylinder I of the gas holder in its up and down movements.
The gas is conveyed through a tube Y which extends to the upper part of the
apparatus and projects down into the water in the vessel A in order to allow the
water carried along by the gas to deposit before the latter passes out through
the branch pipe Y¹ to the consuming apparatuses. The water deposited in this branch
tube Y which rises vertically to its outlet from the apparatus also falls
back into the vessel A.
In all cases the apparatus is provided with a safety valve. In Figures 1 to 3
this valve consists of two tubes Z, Z' which slide one within the other and are
guided by guide rollers, an annular space being left between the said two tubes,
one tube Z being fixed to the sliding cylinder and the other to the main water
vessel A, the latter of the two tubes also being open to the atmosphere. If the
pressure of gas from any exceptional cause should exceed the maximum pre-
determined pressure, the lower end of the tube Z would leave the water in the
main vessel A and the gas would escape through the tube Z' as will be readily
understood by reference to Figure 3.
In Figure 3bis the safety valve is a float valve.
The arrangement comprises a short tube h with a valve i and a second short
tube from which a tube extends into the interior of the vessel a and dips into
the water in the said vessel; the water rises in this tube to a height above the
level in the vessel which corresponds to the pressure of the gas. When the pressure
of the gas is normal, the float k carried by the lever to which is also fixed the
valve i does not touch the liquid in the tube, but as soon as the pressure of the gas
exceeds the predetermined pressure the liquid rises in the tube j, lifts the float k
and the lever and forces the valve i to leave its seat thereby allowing the gas to
escape until the pressure becomes normal. Any risk of explosion is thus avoided.
To provide against cases in which, the water having fallen below a given level in
the vessel A, the float would cease to act, the top of the bell I is connected to the
lever of the valve by a cord or chain, so that if the bell I should rise above a
given limited position it would pull upon the lever and open the valve i thus
allowing any excess of gas to escape into the atmosphere.
In the case where it is desired to obtain gas at a high pressure, the above
described gasometer is replaced by a metal bellows I Figure 6, fixed at its lower
end upon the main vessel A. This bellows is formed of sheet metal rings connected
in pairs around their peripheries.
It will be understood that this bell or gasometer arranged as a bellows forms a
spring and is enabled to expand more or less according to the increasing of the
pressure of gas. But as the resistance offered by the elastic rings which form
the bell, augments rapidly. while the bell extends, the latter can thus be utilised for
high pressures which otherwise would need very heavy ordinary bells. A central
rod 2 resting on the long arm of the regulator is fixed to the top of the bellows and is
guided at its lower end.

page_text: A suitable form of portable apparatus constructed according to our invention is
illustrated in Figures 7 and 8 and comprises a cylindrical vessel the lower part 3,
which forms the gas generator, being full of water up to the level of a cock 4 and
the upper part 5, which is connected with and fixed to the first part, forming the
gasometer and the carbide holder. A sliding cylinder or bell 6 annular in cross
section slides in the outer jacket or vessel 5, and the carbide holder 7, which is
fixed at its lower end around its periphery to the upper part of the gas generator 3
is arranged in the central space of the sliding cylinder or bell. The carbide
holder is provided at its lower part with a funnel or hopper 8 which opens into
the gas generator and the outlet orifice of which is completely closed by a wheel 9
fixed upon an oscillating lever 10 the pivot of which is in the centre of the wheel
and of the outlet orifice of the funnel. Upon one of the arms of the lever 10 the
bell of the gasometer acts through the medium of a rod 11 and to the other arm
thereof we pivot a rod provided with a counterweight 12, the action of which
increases in proportion as the lever approaches the horizontal and the bell 6 rises.
The wheel is provided with a recess 13 which allows carbide to fall in quantities
increasing as the sliding cylinder of the gasometer falls in its outer cylinder.
Figure 7 shews this fall-regulating device in its open position.
The carbide is distributed in the funnel by a register valve 14 similar to that
herein before described and illustrated in Figures 1 to 5 and operated from outside
by a central rod P which passes through the upper end of the carbide holder 7
into a stuffing box and which is provided with a scraper 15 fixed between the
register valve and the stopping or shutter wheel 9.
In the bottom of the gas generator between its base 20 and the inclined plane 18
there is a layer of water into which the acetylene gas can bubble, being drawn from
the upper part of the apparatus through the tube 21 and escaping by a tube 22
connected with the tube conveying the gas to the consumption apparatus.
For illuminating purposes we utunze burners which may vary slightly in con-
struction but which are all based upon the same principle which consists in
surrounding the flame from the acetylene gas with an oxidizing atmosphere whereby
the complete combustion of the carbide is ensured and the flame is rendered more
brilliant and powerful.
A simple burner for domestic lighting purposes, such as is represented in
Figures 9 and 10, comprises a tube 40 in the form of a crescent and provided with
a. screw socket 25 whereby it can be fitted to the supply pipe for the acetylene gas.
The said gas issues through two converging orifices 24, 24 formed in two blocks of
A vertical
steatite or other suitable material fixed on the ends of the tube 40.
tube 26 opens below the points of intersection of the two jets of acetylene gas, the
said tube being provided at the upper part with a gauze cover 27 and communicat-
ing with a reservoir of oxidizing and combustible gas such as oxygen or ozone.
This tube 26 is provided with a sleeve 28 which is held in place by friction and
is perforated with holes 29 for the passage of air and provided with a gauze plug
or cover 30 between the outlet openings for the acetylene gas and the oxygen.
The oxygen or suitable burning gas which flows into the central tube 26 with the
required pressure creates a draught of air and forms with this air a mixture which
immediately surrounds the acetylene gas flame so that the acetylene gas burns in
the said mixture,
The combustion is much more complete than in air and the brilliancy of the
flame is increased in considerable proportions. We can besides vary the intensity of
the flame by varying the proportion of oxygen injected into the said flame.
To form luminous foci with round or polygonal flames for the lanterns of search-
lights, light-houses, etc. we employ an arrangement illustrated in Figures 11
and 12 wherein the acetylene gas flows in through a central tube 31 terminated by
a conical surface and into a series of branches 32 distributed around the said central
tube. Opposite each outlet aperture of the tubes 32 the conical surface which
terminates the central tube has an aperture 33 at a like inclination so that the jets
issuing from the central tube and the branches 32 cut one another at a constant

page_text: angle and form a round or polygonal flame. Below these jets there are arranged
vertical tubes 34 which branch from a ring into which the oxidizing gas, namely,
oxygen or ozone flows.
In another construction of burner illustrated in Figure 13 the acetylene and
oxygen issue into the air in the same manner. The burner is formed of two
crescents or two concentric U-shaped tubes 35 and 36.
The acetylene gas enters the outer tube 35 and escapes in converging jets through
the apertures 37 whilst the oxygen enters the inner tube 36 and also escapes in
converging jets through the apertures 38.
Our burners can in each arrangement be employed singly or in groups or series
of groups upon a single support. They can burn in free air or in lanterns. They
can also be employed in the lanterns of search-lights and the like having lenticular
lenses such as those which are used in warfare, in forts, at sea, in public offices etc.,
in fact, in all apparatuses for projecting light.
We have shewn in Figures 14 and 15 of the drawings our burners applied
respectively to the lanterns of search-lights and the like and to street lamps.
A
In Figure 14 we have shewn a multiple jet burner 40 at the focus of a suitable
lantern reflector 41 which lantern is provided with a lenticular lens 42.
chimney 43 enables a draught to be obtained and a second chimney or jacket 44
perforated with holes covers the reflector and insures the circulation of air in
contact with its sides for preventing them from becoming over heated. In
Figure 15 we have shewn a burner 45 placed in the lantern of a street-lamp;
compressed acetylene gas is employed provided from a cylinder 46 in which it
is compressed and compressed oxygen from a similar cylinder 47, the two cylinders
being arranged in the base of the lamp. Above each cylinder and on the gas
outlet tube leading to the burner we arrange an automatic pressure regulator
shewn more clearly in Figure 16 consisting of a bellows 48 the upper end of which
is fixed and the lower end of which is movable and hinged to the end of a lever 49
keyed upon the plug of a cock 50 which controls the flow of acetylene gas into
the bellows 48. A counterweight 51 on the opposite end of the lever 49 maintains
the bellows 48 closed and the cock 50 opened when the apparatus is at rest.
acetylene gas or the oxygen flowing to the burners passes through the passage 52
and cock 50 and into the bellows 48 which expands more or less until the internal
pressure of the gas equilibrates the counterweight. The gas therefore always flows
from the bellows at a constant pressure, as, directly this pressure tends to increase,
the bellows will gently open and bring back the said pressure to its normal state
and, as soon as the pressure tends to decrease, the bellows will gently close under
the action of the counterweight.
