Year: 1879

page_text: LETTERS PATENT to Léon Vallet, of Liverpool, in the County of Lancaster,
for the Invention of "IMPROVEMENTS IN AND RELATING TO STOPPERS AND
BOTTLES FOR AERATED OR GASEOUS LIQUIDS."
PROVISIONAL SPECIFICATION left by the said Léon Vallet at the Office of
the Commissioners of Patents on the 7th May 1879.

" IMPROVEMENTS IN
AND RELATING TO STOPPERS AND BOTTLES FOR AERATED OR GASEOUS LIQUIDS."
This Invention relates to that method of stoppering bottles where the bottle is
stoppered from the inside, and where the valve or stopper itself is contained inside
the bottle and kept up to its seat by the pressure of gas or air in the bottle.
The bottle to be used with this my present Invention has its neck and mouth of
a size enlarged over the present practice, to receive in such neck or mouth the
internally closing valve hereinafter described, so that when opening the bottle the
said valve will fall back on its hinge into the enlarged neck, and leave the mouth
of the bottle free from obstruction when the bottle is being emptied of its contents.
The stopper consists of an internally hinged valve, which is fitted on to and closes
against a cap or ferrule screwed inside the bottle neck, or outside and over the
bottle neck, or screwing over a split ring which is placed round and under a
shoulder formed on the outside of the bottle neck. In each case an india rubber or
other washer being provided between the cap and ferrule and the glass to hermeti-
cally seal or form an air tight joint. The stopper consists of a valve which is
hinged to the inside of the cap, and is connected to the cap by a lug on the cap and
a jaw on the stopper, or a jaw on the cap and a lug on the stopper. The novelty of
this part of my Invention consists in the way in which I hinge the stopper to the
cap, namely, I use an elongated slot cut in the lug or the jaw of the hinge, so that
the hinge pin, and thereby the stopper, is free to have vertical movement in such
elongated slot, and in this point my Invention differs from ordinary hinged stoppers,
and the stopper is thus allowed to be pushed up and closed by the internal pressure
inside the bottle freely and equally into the valve seat or aperture without a
resistance from the hinge; thus a perfect hermetical joint can be formed by the
stopper.

page_text: When the cap or ferrule is screwed in inside the bottle the washer packing may
be placed at the bottom of the ferrule to form joint with the bottom of the screwed
part, and thus prevent the liquid finding its way between the screwed ferrule and
the bottle.
Internally hinged stoppers constructed according to this my present Invention do
not fall into the liquid when the bottle is opened, which is of great advantage, as it
prevents the splashing of the liquid.
The bottle may be filled by the revolving apparatus as described in the Specifica-
tion of Letters Patent granted to me in 1875, No. 490, or by placing the bottle in
a horizontal position against a feeding tap, the hinged side being higher to allow
the stopper to be pressed in the closing aperture by the internal pressure when the
bottle is released from the feeding tap.
It will be understood that this stopper; as well as the cap or ferrule, may be
made of various suitable materials, such as wood, ebonite, glass, china, metal, silex,
and the stopper or cap is provided with an india rubber or other washer to make
joint.
I would here remark that hinged stoppers have been used prior to this my
Invention, but they have hitherto failed on account of not having been fitted in a
suitable manner to obtain a practical and effective result.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by 2
the said Léon Vallet in the Great Seal Patent Office on the 7th November
1879.
LÉON VALLET, of Liverpool, in the County of Lancaster. "IMPROVEMENTS IN
AND RELATING TO STOPPERS AND BOTTLES FOR AËRATED OR GASEOUS LIQUIDS."
This Invention relates to that method of stoppering bottles where the bottle is
stoppered from the inside, and where the valve or stopper itself is contained inside
the bottle and kept up to its seat by the pressure of gas or air in the bottle.
The bottle to be used with this my present Invention has its neck and mouth of
a size enlarged over the present practice, to receive in such neck or mouth the
internally closing valve hereinafter described, so that when opening the bottle the
said valvo will fall back on its hinge into the enlarged neck, and leave the mouth of
the bottle free from obstruction when the bottle is being emptied of its contents.
The stopper consists of an internally hinged valve, which is fitted onto and closes
against a cap or ferrule screwed inside the bottle neck, or outside and over the
bottle neck, or screwing over a split ring which is placed round and under a
shoulder formed on the outside of the bottle neck. In each case an india rubber or
other washer being provided between the cap and ferrule and the glass, to hermeti-
cally seal or form an air tight joint. The stopper consists of a valve which is
hinged to the inside of the cap and is connected to the cap by a lug on the cap and
a jaw on the stopper, or a jaw on the cap and a lug on the stopper. The novelty
of this part of my Invention consists in the way in which I hinge the stopper to
the cap, namely, I use an elongated slot cut in the lug or the jaw of the hinge, so

page_text: that the hinge pin, and thereby the stopper, is free to have vertical movement in
such elongated slot, and in this point my Invention differs from ordinary hinged
stoppers, and the stopper is thus allowed to be pushed up and closed by the internal
pressure inside the bottle freely and equally into the valve seat or aperture without
a resistance from the hinge; thus a perfect hermetical joint can be formed by the
stopper.
When the cap or ferrule is screwed inside the bottle the washer packing may be
placed at the bottom of the ferrule to form joint with the bottom of the screwed
part, and thus prevent the liquid finding its way between the screwed ferrule and
the bottle.
Internally hinged stoppers constructed according to this my present Invention do
mot fall into the liquid when the bottle is opened, which is of great advantage, as it
prevents the splashing of the liquid.
The bottle may be filled by the revolving apparatus as described in the Specifi-
cation of Letters Patent granted to me in 1875, No. 490, or by placing the bottle in
a horizontal position against a feeding tap, the hinged side being higher to allow
the stopper to be pressed in the closing aperture by the internal pressure when the
bottle is released from the feeding tap.
It will be understood that this stopper, as well as the cap or ferrule, may be made
of various suitable materials, such as wood, ebonite, glass, china, metal, silex, and
the stopper or cap is provided with an india rubber or other washer to make
joint.
I would here remark that hinged stoppers have been used prior to this my
Invention, but they have hitherto failed on account of not having been fitted in a
suitable manner, to obtain a practical and effective result.
The beforegoing being the nature, object, and purposes of my Invention, I will
now proceed to illustrate how the same may be practically applied, and describe
forms of stoppers (and bottles such as are suitable for carrying my Invention into
practice, and for that purpose I have hereunto attached a Sheet of Drawings marked
with letters and figures of reference corresponding with those in the following
explanation, like letters and figures being used to denote the same or corre-
sponding parts throughout the various views and Figures.
Figure 1 is a sectional elevation illustrative of a bottle and a stopper constructed
according to my Invention.
•
Figures 2, 3, 4, 5, and 6 are modifications of my Invention.
A is a portion of a bottle, shown broken off. The neck or mouthpiece B is
slightly enlarged over the present practice to receive an internally closing valve C,
hereinafter described, so that when opening the bottle the valve C will fall back
into the enlarged neck B, and leave the mouth D free from obstruction.
The stopper consists of an internally hinged valve C, provided with an india
rubber ring J, which is fitted onto and closes against the cap or ferrule E,
which is screwed inside the bottle neck as shown at Figure 1 or as shown
at Figure 2, or outside the bottle neck, as shown at Figure 3, or outside the
bottle neck and round a split screwed washer G, as shown at Figure 4. An
hermetical joint between the cap E and the bottle A being obtained in each
instance by the elastic washer F. The stopper or valve C is hinged to the inside
of the cap E at H by a jaw a on the cap E and a lug b on the stopper C. The
novelty of this part of my Invention consists in the use of an elongated hole or
slot e arranged so that the hinge pin, and thereby the stopper C, is free to have
vertical movement up against the seat, which is formed by the cap or ferrule E.
The stopper C is thus allowed to be pushed up freely and equally, and closed
against the seat formed by the cap E by the internal pressure inside the bottle.
Figure 1 illustrates the cap or ferrule E in plan.
Upon reference to Figure 5 it will be seen that the hinged stopper C is provided
with a collar K, and the seat of the cap E is arranged to receive the india rubber
washer J, so as to practically conceal it and keep it from contact with the liquid in
the bottle.

In Figure 6 it will be seen that the valve C is of spherical or ball shape, and it is
held by the forked hinge piece b. Figure 6ª is a plan of the stopper shown at
Figure 6.
