I, THÉODORE STERNE, of 49, Rue de la Victoire, Paris, in the Republic of
France, Civil Engineer, do hereby declare the nature of this invention to be as
follows:
My invention has for its object a new arrangement of closing means for cap-
sules or cartridges containing compressed or liquefied gases or liquids under pres-
sure; it is applicable to all capsules or cartridges whatever may be their form
or construction, or whatever may be the material of which they are made.
It consists in forming in any convenient part of the capsule or cartridge, an
opening through which it is charged with any kind of compressed or liquefied
gas or liquid under pressure. These capsules or cartridges, made of any kind
of material which is capable of resisting the pressure of the gas, are closed by
a cover with or without nozzle which has no fixed connection with the surface
to be closed, but only a movable connection obtained by adherence between the
cover and the capsule by any suitable means.
As an example, for capsules made of iron or steel, the means of adherence
resulting from the magnetisation of the parts. Equally, in the case of capsules
made of iron or steel or of all other suitable materials, I may employ the adher-
ence caused by the interposition between the cover and container, of any suitable
agglutinant body.
The essential characteristic of this invention consists in the fact that the
dimensions of the charging orifice are calculated in such a manner that the
pressure of gas or liquid in contact with the surface of the cover with which it
comes into contact may be less than the adhesive force existing between the
cover and the container.
To fill the capsules or cartridges I may place them in a receiver or charging
chamber, setting each row of capsules or cartridges in trenches or channels
formed in the said receiver or charging chamber. This being done I close
hermetically this said receiver, and I cause the current of compressed or liquefied
gas or liquid under pressure to pass therein. Each of the capsules or cartridges
is placed a little distance from its cover, which latter is held by pins, hooks, or
claws which form a part of the cover of the receiver or charging chamber. It
results from this arrangement that the charging is effected very rapidly owing
to the space existing between the capsule and its cover, which remain held at
the same distance apart.
To apply the capsules or cartridges upon the covers, it is only necessary to give

page_text: the receiver or charging chamber a slight inclination. From this it results
that each of the capsules or cartridges, in sliding in the groove in which it is
supported, comes into contact with the cover, which is then automatically held
upon the body of the capsule or cartridge by the agglutinant which has been
previously placed upon the surface of the capsule or cartridge and of the cover,
or if the agglutinant is replaced, as herein before described, the closing may be
effected by the movable cover of the receiver or charging chamber being caused
to slide and thus press the covers against the openings of the capsules, cart-
ridges, &c.
To use capsules or cartridges thus filled and closed, it is sufficient to place
them in a stopper or closing apparatus of any suitable form attached to a bottle
or other receiver (if, for example, capsules containing carbonic acid gas are being
employed to manufacture aerated water) and, by means of any convenient instru-
ment, to detach the cover of the capsule or cartridge to allow the immediate
escape of the gas which it contains into the water to be aerated.
The immense advantage of this system of closing capsules will be readily
understood because it permits of replacing the perforation which has hitherto
been employed to allow the escape of gas or liquid contained in the capsule or
cartridge, which perforation placed the capsule or cartridge out of use and pre-
vented it ever being used a second time. There results from this arrangement
of closing an appreciable economy because the same capsules or cartridges may
be used very many times.

A New or Improved Method of Closing Capsules or Cartridges con-
taining Compressed or Liquefied Gases or Liquids under Pressure.
I, THÉODORE STERNÉ, of 49, Rue de la Victoire, Paris, in the Republic of
France, Civil Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention has for its object a new arrangement of closing means for cap-
sules or cartridges containing compressed or liquefied gases or liquids under pres-
sure; it is applicable to all capsules or cartridges whatever may be their form
or construction or whatever may be the material of which they are made.
It consists in forming in any convenient part of the capsule or cartridge, an
opening through which it is charged with any kind of compressed or liquefied
gas or liquid under pressure. These capsules or cartridges, made of any kind
of material which is capable of resisting the pressure of the gas, are closed by
a cover with or without a nozzle or projection which has no fixed connection with
the surface to be closed but only a movable connection obtained by adherence
between the cover and the capsule by any suitable means.
As an example, for capsules made of iron or steel, the means of adherence
may be that resulting from the magnetisation of the parts.
Equally, in the case of capsules made of iron or steel, or of all other suitable
materials I may employ the adherence caused by the interposition between the
cover and container of any suitable agglutinant body.

page_text: The essential characteristic of this invention consists in the fact that the
dimensions of the charging orifice are calculated in such a manner that the pres-
sure of the enclosed gas or liquid on the free surface of the cover with which it
comes into contact may be less than the adhesive force existing between the cover
and the container.
In order that the invention may be more clearly understood I have shown in
the accompanying drawings by way of example only at Figures 1, 2, 3 and 4
different forms of capsules A, A1, A2, A3 and of their covers B and B¹, the latter
being provided with a nozzle or projection B² to enter the aperture in the capsule.
Fig. 5 shows a longitudinal section, part being broken away, of the arrange-
ment which I employ to fill the capsules.
Fig. 6 is a transverse section on a smaller scale of the same arrangement.
Fig. 7 shows in longitudinal section one of the means which I employ to place
the covers upon the capsules.
To fill the capsules or cartridges I may place them in a receiver or charging
chamber D, setting each row of capsules or cartridges A in trenches or channels b
formed in the said receiver or charging chamber D; this having been done, I
close hermetically this said receiver or charging chamber and I cause the current
of compressed or liquefied gas or liquid under pressure to pass therein. Each of
the capsules or cartridges A is placed at a little distance from, and with its
charging orifice a adjacent to its cover B which latter is held by pins, hooks or
claws C which form a part of the cover of the receiver or charging chamber D.
It results from this arrangement that the charging is effected very rapidly
owing to the space existing between the capsule and its cover which remain, held
at the same distance apart.
To apply the capsules or cartridges upon the covers, it is only necessary to
give the receiver or charging chamber Da slight inclination as shown at Fig. 7.
From this it results that each of the capsules or cartridges by sliding in the
groove in which it is supported comes into contact with its cover which is then
automatically held upon the body of the capsule or cartridge by the agglutinant
which has been previously placed upon the surface of the capsule or cartridge
and of the cover or if the agglutinant is replaced as hereinbefore described the
closing may be effected by the movable cover of the receiver or charging chamber
being caused to slide from right to left and thus press the covers against the
openings of the capsules, cartridges &c.
To use capsules or cartridges thus filled and closed, it is sufficient to place
them in a stopper or closing apparatus of any suitable form attached to a bottle
or other receiver, if for example capsules containing carbonic acid gas are being
employed to manufacture aërated water and by means of any convenient instru-
ment to detach the cover of the capsule or cartridge to allow the immediate escape
of the gas which it contains into the water to be aërated.
The immense advantage of this system of closing capsules will be readily
understood because it permits of avoiding the perforation which has hitherto
been employed to allow the escape of gas or liquid contained in the capsule or
cartridge, which perforation placed the capsule or cartridge out of use and pre-
vented it ever being used a second time.
There results from this arrangement of closing an appreciable economy because
the same capsules or cartridges may be used very many times.
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: -
A new or improved method of closing capsules or cartridges containing gas
or liquids under pressure, consisting in forming at any convenient point of the
capsule, cartridge or receiver whatever an opening in combination with a movable
cover held by simple adherence, cohesion or magnetism, said opening having

page_text: such dimensions that the pressure exerted thereon by the enclosed gas or liquid
may be less than the force of adherence produced by the contact of the capsule
and its cover substantially as herein set forth.
