Improvements in Bottle Stoppers.
I, SÉBASTIEN LACAVALERIE, of Salvador de Leon & Locarras No. 95, Caracas,
Venezuela, 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 bottle stoppers, and the object thereof is to provide an
improved device of this class which is simple in construction and operation an1
which is pivotally connected with a bottle and arranged in such position as to be
reused when desired; a further object being to provide means for securing the
stopper in place on the bottle so as to close the same.
The invention is fully disclosed in the following Specification, of which the
accompanying drawings form a part in which;
Fig. 1, is a side elevation of the neck of a bottle, provided with my improve-
ment;
Fig. 2, a similar view at right angles to that of Fig. 1 ; and
Fig. 3, a transverse vertical section of the neck of a bottle with the stopper
removed, the stopper being also shown in section.
In the practice of my invention, I provide the neck A, of a bottle with an annular
shoulder B, near the top thereof, and below said annular shoulder is placed an open
ring or band C.
My improved stopper D is preferably composed of wood and is of the form in
longitudinal section shown in Fig. 3, being provided with a circular head d and being
tapered to the inner end as shown at d¹ and being provided with an annular groove
or recess d², in which is placed a rubber or other flexible washer E having a central
opening or perforation, and below the washer E the stopper is provided with a
head d, by which the washer is held in place.
The stopper D, is pivotally connected with the ring or band C, by means of a
link F, provided with ends which are inwardly directed and adapted to enter
perforations formed in the outwardly directed ends C₁ of the ring or band C.
Pivotally connected with the ring or band C, on opposite sides thereof, is a
yoke the ends of which are connected with said band and the upper part of which
is adapted to bear upon the top of the stopper D, when the latter is in position as
shown in Figs. 1 and 2, the upper part of said yoke being inwardly bent or curved
as shown at g so as to give a spring action thereto, said yoke being also composed
of spring wire.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing. When the stopper is placed
in position to close the bottle, the washer E will be contracted and folded adjacent
to the sides thereof, and thus securely close the nozzle of the stopper and the
yoke G will be pressed over the top of the bottle, said stopper being provided in
the upper surfaces of the head thereof, with a groove or recess K in which the
transverse portion g of the yoke is adapted to rest.
By means of this construction, I provide a simple and effective stopper which
may be used to close or seal a bottle, and which may be reused as often as desired
and which is always in position for use.
My invention is not limited to the exact form, construction and arrangement of
parts herein described, and I therefore reserve the right to make such alterations

page_text: therein, and modifications thereof, as fairly come within the scope of the
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. A bottle, the upper end of the neck of which is provided with an annular
shoulder, a ring or band secured below said shoulder, a stopper pivotally connected
with said ring or band, and a yoke pivotally connected with said ring or band and
adapted to hold said stopper in position, substantially as shown and described.
2. The combination with the neck of a bottle, which is provided with an annular
shoulder, of a ring or band secured below said annular shoulder, a stopper
pivotally connected with said ring or band, and adapted to be held adjacent to the
side of the neck when not in use, and a yoke pivotally connected with the ring or
band and adapted to hold said stopper in position to close the neck or nozzle of
the bottle, substantially as shown and described.
3. A bottle stopper, composed of wood or similar material and provided near its
smaller end with an annular washer of rubber or similar material, substantially as
shown and described.
4. A bottle stopper provided near its smaller end with an annular washer of
rubber or similar material which is adapted to be folded adjacent to the sides of
the stopper, when the latter is placed in the neck or nozzle of the bottle, and
means connected with the neck or nozzle of the bottle for holding the stopper
therein, substantially as shown and described.
5. The combination with a bottle, of a stopper connected with the neck thereof,
said stopper being provided with an annular washer of rubber or similar material
which is secured thereto, near the smaller end thereof, and means connected with
the neck of the bottle for holding the stopper therein substantially as shown and
described.
