Improvements in or relating to Means for Regulating the Production
of Acetylene Gas and in Lamps therefor.
We, EMILE GOSSART and HENRY CHEVALLIER both of 45 Rue Cours d'Albret,
Bordeaux (Gironde) France Manufacturers do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in or relating to means for regulating
the production of acetylene gas and in lamps therefor.
The perfect autoregulation of our lamp, with the burners usually used for
burning acetylene gives to it an absolutely steady flame,
The water falls drop after drop from an upper receiver on the base of the lamp
which contains carbide of calcium, by passing through capillary tubes preferably
bent several times. When the pressure of the gas is insufficient, the water drop
falls in order to form gas; when on the contrary the pressure becomes sufficient,
the equilibrium is established between the amount of the hydrostatic and capillary
pressures of the drop on one side and the pressure of the gas on the other side, and
the formation of the gas stops, until a new quantity of water is necessary.
We thus avoid all complicated mechanisms which also give a much less delicate
autoregulation.
We may mention also that these same capillary tubes can serve as safety valves
in the case of a too large production of gas, and thus prevent any accident. The
gas under pressure then presses the water back in the capillary tubes and escapes
through the water in the receiver. Any chance of explosion is avoided and the
only possible inconvenience would be a slight odour caused by the escaped gas.
One can also remedy accidental obstruction of the capillary tubes by closing the
tap of the combustion burner, which forces the compressed gas in the lamp to open
a brisk passage through these tubes to clean them.
The lamp consists therefore only of a receiver in glass or metal or any other
material, composed of two parts, which we call the base and the capital to be
screwed or mounted by hooks securely one upon the other.
The base contains the carbide of calcium arranged in a basket, which is adapted
for the best possible distribution of the chemical action.
The capital or cover of the lamp, carries in its centre the water receiver, the
bottom of which is traversed by the tube of the gas burner and by one or more
capillary tubes.

page_text: One capillary tube alone is sufficient for a lamp of 10 candle power operating
3 hours with 150 grams of carbide. One uses. two of them, for.. a lamp. about
20 candle power and three for a lamp of 30 candle power.
The number of the tubes and the dimensions, of the Imp can also be calculated
very easily according to the candle power one desires and the duration of the
light.
We can adapt our autoregulating capillary tube to all forms of lamps and to
all burners for lighting by acetylene.

Improvements in or relating to Means for Regulating the Production
of Acetylene Gas and in Lamps therefor.
We, EMILE GOSSART and HENRY CHEVALLIER both af 45 Rue Cours d'Albret,
Bordeaux, (Gironde), in the Republic of France, Manufacturers 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 or relating to means for regulating
the production of acetylene gas and in lamps therefor."
The perfect autoregulation of our lamp, with the burners usually used for
burning acetylene gives to it an absolutely steady flame,
The water falls drop after drop from an upper receiver on the base of the lamp
which contains carbide of calcium, by passing through capillary tubes preferably
bent several times. When the pressure of the gas is insufficient, the water drop
falls in order to form gas; when on the contrary the pressure becomes sufficient,
the equilibrium is established between the amount of the hydrostatic and capillary
pressures of the drop on one side and the pressure of the gas on the other side, and
the formation of the gas stons, until a new quantity of water is necessary..
We thus avoid all complicated mechanisms which also give a much less delicate
autoregulation.
We may mention also that these same capillary tubes can serve as safety valves
in the case of a too large production of gas, and thus prevent any accident. The
gas under pressure then presses the water back in' the capillary tubes and escapes
through the water in the receiver. Any chance of explosion is avoided and the
only possible inconvenience would be a slight odour caused by the escaped gas.
One can also remedy accidental obstruction of the capillary tubes by closing the
tap of the combustion burner, which forces the compressed gas in the lamp to open
a brisk passage through these tubes to clean them.
The lamp consists therefore only of a receiver in glass or metal or any other
material, composed of two parts which we call the base and the capital to be
screwed or mounted by hooks securely one upon the other.
The base contains the carbide of calcium arranged in a basket, which is adapted
for the best possible distribution of the chemical action.
The capital or cover of the lamp, carries in its centre the water receiver, the
bottom of which is traversed by the tube of the gas burner and by one or more"
capillary tubes.
One capillary tube alone is sufficient for a lamp of 10 candle power operating
3 hours with 150 grams of carbide. One uses two of them for a lamp about
20 candle power and three for a lamp of 30 candle power.

page_text: The number of the tubes and the dimensions of the lamp can also be calculated
very easily according to the candle power one desires and the duration of the
light.
We can adapt our autoregulating capillary tube to all forms of lamps and to
all burners for lighting by acetylene.
The annexed drawing shows annaratus operating in a perfect manner, but which
could be modified considerably according to their intended use, size, and design.
In all the figures A indicates the water-receiver, B the bent capillary regulating
tubes which distribute the water in drops on the carbide; C the carburet receiver
or generator, D the tube through which the disengaged gas leaves the generator
in order to pass to the burner; this tube traverses preferably the water receiver
which serves thus as a refrigerator.
In the examples shown the carbide is contained in a movable basket which can
he easily put in place or taken away when the generator is opened.
In Figs. 1 and 2 this basket has a central cone which facilitates the uniform
distribution of the water on the carburet.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. Improved apparatus for producing, regulating, and burning acetylene gas
with an autoregulator composed essentially of a water receiver connected with a
carbide receiver by means of one or more capillary tubes, the number, length and
diameter of which are proportioned according to the power of the apparatus.
2. In an apparatus as under Claim 1 the arrangement which consists of bending
the capillary tubes as shown in order to give them the desired length without
occunving too much room.
3. In an apparatus as under Claim 1 the arrangement in the carbide receiver,
of a movable basket with a central cone in order to receive the carbide, for the
purpose of facilitating the cleaning as well as the equal distribution of water on
the carbide.
4. The apparatus for producing acetylene gas constructed and combined as
described and shown in the annexed drawing. All substantially as illustrated
and set forth.
