PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Production of Acetylene.
We, EMILE VICTOR PREVOST, of 12, Impasse Saumon, OLIVIER RAUS, of 32,
Boulevard Haussman, and ALBERT CERKEL, of 26, Rue Bergère, all in the City
of Paris, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a generator employed in portable apparatus
for lighting rooms, vehicles, such as velocipedes and the like, by means of
acetylene.
The bottom of the lamp or generator carries a capillary tube which is slit longi-
tudinally in such a manner that it may contain a strip of blotting paper or other
material assuring capillarity.
The lamp properly so called is formed of tubes joined together to facilitate
cleaning. The upper portion of the lamp is closed by a cap in which openings
are suitably arranged for the outlet of the acetylene gas to the burner.
From the preceding it will be easily understood that the generator being filled
with calcium carbide and placed in a tube fixed to the receiver containing water,
this water will enter the lower end of the capillary tube will ascend the paper
strip and will moisten the calcium carbide contained in the generator.
The acetylene gas generated in the lamp will pass to the burner.
When the gas pressure rises, the water will be driven back and as soon as this
pressure decreases, the water will rise by capillarity in the tube and will gradually
inoisten the carbide and thus produce gas proportionally to its consumption.

We, EMILE VICTOR PREVOST, of 12, Impasse Saumon, OLIVIER RAUS, of 32,
Boulevard Haussman, and ALBERT CERKEL, of 26, Rue Bergère, all in the City
of Paris, 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 has for its object a generator employed in portable apparatus

page_text: In order that our said invention may be fully understood it is illustrated in the
accompanying drawings.
In this drawing Figure 1 is a vertical section of a lump or generator made
according to this invention.
Figure 2 is a horizontal section of the same on the lines 1-2 of Figure 1.
The bottom a of the lamp or generator carries a capillary tube b, which is slit
longitudinally in such a manner that it may contain a strip c of blotting paper
or other material assuring capillarity.
This tube may also be provided with holes and surrounded by a wick for assur-
ing moisture by capillarity.
The lamp d properly so called, is formed of tubes joined together to facilitate
cleaning. The upper portion of the lamp is closed by a cap e, in which openings f
are suitably arranged for the outlet of the acetylene gas to the burner.
From the preceding it will be easily understood that the gonerator being filled
with calcium carbide and placed in a tube fixed to the receiver containing water,
this water will enter the lower end of the capillary tube b, will ascend the paper
stripe and will moisten the calcium carbide contained in the generator.
The acetylene gas generated in the lamp will pass to the burner.
When the gas pressure rises, the water will be driven back, and as soon as
this pressure decreases, the water will rise by capillarity in the tube b, and will
gradually moisten the carbide, and thus produce gas proportionally to its con-
sumption.
It will be understood that the shape, dimensions, details and materials
employed for the construction of this apparatus, may be varied without in any
way altering the principle of the invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
י
The improvements in apparatus for the production of acetylene gas substan-
tially as described and shown in the drawings.
