PROVISIONAL SPECIFICATION.
Improvements in Stoppers or Closures for Vessels, such as Jars, and
the like.
We PAUL BREDEVILLE, and ROBERT PATUREL, both of 15 Rue des Halles, Paris,
France, Merchants, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in stoppers or closures for vessels such as
jars and the like.
An arrangement of stopper or closure according thereto is illus-
trated in the annexed sheet of drawings,
Fig. 1 being an elevation, partly in section, of the stopper applied to a jar,
Fig. 2 a sectional view of the stopper to an enlarged scale.
B is the stopper
A is the jar or vessel which may be of any shape and material.
which at first enters the neck of the vessel loosely after which, on the knob C being
turned, the peripheral collar or ring D consisting of a thin circular flexible rubber
strip is caused to swell up in the form of a half-cable moulding and bears firmly against
the circular wall of the neck of the vessel.
Referring to the detailed view Fig. 2,
E is a metal plate whose circular rim receives a flange or collar F fastened thereto
by solder or by turning over the same.
The bottom of this plate rises to receive a central screw to which it is attached by
means of two nuts a a' tightened up and then soldered as shewn.
Around the collar F is placed the flexible rubber ring D.
The parts just described constitute the lower portion of the plug of the stopper.
The intermediate portion comprises a metallic cap G, of nickel or other metal, per-
forated at the centre with a hole through which the central screw passes and ending
at its lower part in a thin rim d which fits accurately and externally around the
collar F. This rim, when pressure is applied to the cap G, enters between the collar F
and the ring D with the result, after the seat d' has come to bear upon the top of the
ring, of depressing it, causing the said ring to swell out all around and thus increase
the diameter of the part between its upper and lower edges. This tightening move-
ment of the cap is effected by means of the knob C which is screwed upon the
central stem b. By the use of our invention jars and other vessels can be effectively
stoppered and unstoppered very quickly.

COMPLETE SPECIFICATION.
Improvements in Stoppers or Closures for Vessels, such as Jars, and.
the like.
We, PAUL BREDEVILLE, and ROBERT PATUREL, both of 15 Rue des Halles, Paris,
France, Merchants, 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 stoppers or closures for vessels such as
jars and the like.
An arrangement of stopper or closure according thereto is illus-
trated in the sheet of drawings filed with our provisional specification. Referring to
these drawings.

page_text: Fig. 1 is an elevation, partly in section, of the stopper applied to a jar ;
Fig. 2 is a sectional view of the stopper drawn to an enlarged scale."
A is a jar or vessel which may be of any suitable shape and material; B is a stopper
or closure (hereinafter called a stopper) provided with a peripheral collar or ring D
of suitable flexible material such as india rubber. The arrangement is such that the
stopper can freely enter the neck of the vessel, and on the knob C being turned, the
collar or ring D will be caused to swell or bulge out in the form of a half-cable
moulding and bear firmly against the inner surface of the circular neck of the
vessel.
Referring to the detailed view Fig. 2, E is a metal plate whose circular rim
receives a flange or collar F fastened thereto by solder or by turning over the
adjacent edges of the same. The bottom of this plate rises at the centre to receive
a central screw to which it is attached by means of two nuts a a¹ tightened up and
then soldered as shewn. Around the collar F is placed the thin flexible rubber
ring D.
The parts just described constitute the lower portion of the plug of the stopper.
The intermediate portion comprises a metallic cap G, of suitable metal such as nickel
formed at the centre with a hole through which the central screw 6 passes, and ending
at its lower edge in a thin rim d which fits accurately and externally around the
collar F.
This rim, when pressure is applied to the cap G, enters between the collar F and
the ring D so that after the seat d' has been caused to bear upon the top of the ring,
it depresses the ring and causes the same to swell out all around as indicated in dotted
lines and thus increase the diameter of the part between its upper and lower edges.
The flange or collar F supports the thin ring D and ensures that this ring when
compressed between the bottom plate a and the seat d¹ shall swell outward and not
inward and shall thereby effect a tight closure with the bottle neck. This tightening
movement of the cap is effected by means of the knob C which is screwed upon
the central stem b. The plate E can be connected to the upper edge of the flange F,
instead of to the lower edge as in the example shown, the Hange being then formed
at its lower edge with an annular grooved seat to receive the ring D. By the use of
stoppers or closures according to this invention, jars and other vessels can be quickly
and effectively stoppered and unstoppered.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
―
1. A stopper or closure for vessels such as jars and the like, constructed in two
parts adapted to be moved to and from each other and with a flange or collar such
as F, surrounded by a thin ring of suitable flexible material such as india rubber,
substantially as herein before described for the purpose specified.
2. Our improved stopper or closure for vessels such as jars and the like, substantially
as described and shown.
