PROVISIONAL SPECIFICATION.
Apparatus for Filling and Closing Metal Capsules or Containers
Submitted to Great Internal Pressure, and Having Fine Necks
with Small Inlet Apertures.
I, EMILE STERN, of 3 bls Rue d'Athènes, Paris, in the Republic of France,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object apparatus for filling and closing metal capsules
or containers submitted to great internal pressure, and having fine necks with small
inlet apertures which may be formed direct in the substance of the neck or in a
lining therein of a different material, such for instance as ebonite.
I place a capsule in a die formed with an aperture fitting the capsule and fitted
with a plunger formed on its end to fit the base of the capsule; in connection with
this die is a coacting die, which is movable within an adjustable sleeve screwing
into the framing and is pressed outwards by a spring. The two dies are separated
from each other a sufficient distance to enable the capsule to be placed within the
first-named die. This die with its plunger is then moved into contact with the
coacting die, which it moves, against the pressure of a spring, flush with the face
of the sleeve, when the nozzle of the capsule will be pressed against the month of a
small recess in a fixed die with sufficient force to make a tight joint. The fixed
die fits a recess in the coacting die, and its recess communicates by a passage with
the supply of gas or fluid under high pressure. Then, by opening an inlet valve
placed in a suitable position, the compressed gas or fluid is caused to pass through
the neck of the capsule and fill the latter. The said valve is then closed and the
plunger in the first-named die is moved outwards towards the coacting die, thereby
forcing the neck of the capsule into the small recess of the fixed die, which recess,
being smaller than the original size of the neck of the capsule, compresses or
crushes the neck so as to effectually close the inlet aperture thereof. The first-
named die and its plunger are then separated from the coacting die, when the
spiral spring or other suitable means will press the latter die outwards from the
sleeve, whereby said die, which is formed with a shoulder fitting the shoulder of
the capsule, will remove the closed up neck of the capsule from the closing recess
in the fixed die, thereby freeing the capsule and causing it to fall out. It will be
evident that the neck closing die may be caused to move to close the neck of the
capsule instead of moving the plunger in the first-named die for said purpose. If
desired other means may be employed for ejecting the filled and closed capsule.
It will be evident that various modifications may be made in the construction
and arrangement of the various parts without departing from the peculiar character
of my invention.

Submitted to Great Internal Pressure, and Having Fine Necks
with Small Inlet Apertures.
I, EMILE STERN, of 3 Rue d'Athénes, Paris, in the Republic of France,
Civil Engineer do hereby declare the nature of my invention for apparatus for
filling and closing metal capsules or containers submitted to great internal pressure
and having fine necks with small inlet apertures, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
The invention has for its object, apparatus for filling and closing metal capsules or
containers submitted to great internal pressure, and having fine necks with small
inlet apertures which may be formed direct in the substance of the neck or in a
lining therein of a different material, such for instance, as ebonite. I will describe
my invention by the aid of the accompanying drawings.
I place a capsule a in a die formed with an aperture fitting the capsule and
fitted with a plunger c formed on its end to fit the base of the capsule; in
connection with this die b is a die d which is movable within an adjustable sleeve e
screwing into the framing f and is pressed outwards by a spring g. The dies b
and d are separated from each other a sufficient distance, as shown at Fig. 1, to
enable the capsule a to be placed within the die b. The die b with its plunger c is
then moved into contact with the die d which it moves, against the pressure of the
spring g, flush with the face of the sleeve e as shown at Fig. 2 when the nozzle of
the capsule will be pressed against the mouth of the small recess in the fixed
die h with sufficient force to make a tight joint. The die h fits a recess in the die d
and its recess communicates by a passage h with the supply of gas or fluid under
high pressure. Then by opening an inlet valve, placed in a suitable position, such
ash, the compressed gas or fluid is caused to pass through the neck of the capsule
and fill the latter. The said valve is then closed and the plunger e in the die bis
moved outwards towards the die d thereby forcing the neck of the capsule into the
small recess of the fixed die has shown at Fig. 3, which recess, being smaller
than the original size of the neck of the cap-ule, compresses or crushes the neck so
as to effectually close the inlet aperture thereof. The die b and plunger c are then
separated from the die d when the spiral spring g or other suitable means will press
the die d outwards from the sleeve e, whereby said die d, which is formed with a
shoulder d fitting the shoulder of the capsule a, will remove the closed up neck of
the capsule from the closing recess in the die h, thereby freeing the capsule and
causing it to fall out. It will be evident that the parts e, f, h may be caused to
move to close the neck of the capsule instead of moving the plunger c for said
purpose. If desired other means may be employed for ejecting the filled and
closed capsule. It will be evident that various modifications may be made in the
construction and arrangement of the various parts without departing from the
peculiar character of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The apparatus substantially as herein set forth, for filling and closing metal
capsules or containers having fine necks and small inlet apertures.
2. In apparatus for filling and closing metal capsules or containers having fine
necks and small inlet apertures, the combination of a die to receive the body of the

page_text: capsule, a plunger in said die to fit the base of the capsule, a spring actuated die to
receive the shoulder of the capsule, a die fixed in the frame and having a recess
somewhat smaller than the neck of the capsule, a passage connecting said last
mentioned recess with the supply of gas or fluid under pressure and a valve to open
and close the conduit of the compressed gas or fluid, the whole being operated so as
first to press the neck of the capsule against the mouth of the small recess in the
die connected with the supply of compressed gas or fluid for the filling operation,
then to force the neck of the capsule into the said small recess to close the aperture
in said neck and finally to eject the filled and closed capsule substantially as herein
set forth.
3. In apparatus for filling and closing metal capsules or containers having fine
necks and small inlet apertures, the combination of dies to receive the capsule, a
recess in one of such dies communicating by a passage with the supply of compressed
gas or fluid and somewhat smaller in diameter than the neck of the capsule, means
for pressing the neck of the capsule against the mouth of said recess with sufficient
force to secure a tight joint during the filling operation, means for opening and
closing the passage for the compressed gas or fluid, means for closing the neck of
the filled capsule or container by forcing it into the small recess of the die
communicating with the supply of compressed gas or fluid and means for liberating
the filled and closed capsule or container substantially as herein set forth.
