PROVISIONAL SPECIFICATION.
Improvements in and relating to Bottle Stoppers.
We, ALFRED ALEXANDRE LEGRAND, of 9 Rue Saint Ambroise, Gunsmith,
and EMILE FURRER, of 3 Rue de Bondy, Merchant, both of Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to a bottle stopper which is designed to protect liquors of
hygienic qualities, mineral waters, special medicaments, alcohol and other liquids
against fraud.
This stopper, preferably made of metal, is provided with a valve and with a
spring for fixing it in the neck of the bottle, and for preventing it from leaving.
It is put in the neck of the bottle before the latter is finally closed, and it enables
the liquid to be poured out, but precludes the introduction of other liquid with
intent to defraud.
We will first describe one arrangement of our apparatus, and then proceed to set
forth a modification of the same, reference being made to the accompanying
drawing.
Figure 1 represents a section of a bottle neck made interiorly of cylindrical
shape.
A designates a circular groove provided in the cylindrical part of the bottle
neck.
Figure 2 represents a cylindrical tube B having at its upper part an inclined
plane C, this tube being traversed in proximity to the inclined plane by another
cylindrical tube E serving to receive a spring which has for its object to force the
two catches D outwards and fix them in the groove A, Figure 1, for retaining the
stopper in the neck.
At the lower end of the tube B is fixed a cone F pierced at its centre for the
passage of a rod G, around which are provided several openings for the outlet of
the liquid. At its upper extremity the rod G receives the valve H and at its
lower extremity is provided a ball I serving as a counterweight for lowering the
said valve.
The tube B, Figure 2, is provided on the outside with thin projections J of
metal or rings of cork or india rubber surrounding the said tube for facilitating the
adhesion of the stopper to the interior periphery of the neck. This stopper may
be constructed of any other suitable material, more particularly of tin, as the latter
does not deteriorate and leaves no taste.
A stopper constructed in this manner is placed in the neck of the bottle as shown
in Figure 3.
In the modification represented in Figures 5 to 10 the stopper valve is con-
structed so as to enable the same to be easily returned to its seat either by means
of a metallic ball or by the action of the valve itself by augmenting its bulk or the
height of the fall. Moreover, in the former arrangement we employ a cork stopper
for closing the bottle, whilst in the second arrangement the groove A is nearer to
the orifice of the neck in which case we use a metallic screw-stopper in lieu of the
said cork stopper.
Figure 4 represents the said modification of the stopper in section through the
centre.
Figure 5 shows a modification of the stopper valve which is slightly conical and
truncated.

displaced in a lantern d which may be slightly conical and truncated, or which may
be conical and have a rounded top, as shown in Figure 7.

certain bulk and falls easily back upon its seat as soon as the bottle is put upright
again.
In the arrangement illustrated in Figure 8 the lantern is truncated and has a
rounded top. It receives interiorly the valve which is likewise truncated and
provided with a rounded top, but this valve is hollow and receives a metallic ball.

which the said valve fits; this projection may also be provided on the valve seat
in the other modifications.

COMPLETE SPECIFICATION.
Improvements in and relating to Bottle Stoppers.
We, ALFRED ALEXANDRE LEGRAND, Gunsmith, of 9 Rue Saint Ambroise,
and EMILE FUERER, Merchant, of 3 Rue de Bondy, both of Paris, in the
Republic of France, 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 :-
Our invention relates to a bottle stopper which is designed to protect liquors of
hygienic qualities, mineral waters, special medicaments, alcohol and other liquids
against fraud.
The stopper, preferably made of metal, is provided with a valve and with a
spring for fixing it in the neck of the bottle and for preventing it from leaving the
same.
It is put in the neck of the bottle before the latter is finally closed and it enables
the liquid to be poured out but precludes the introduction of other liquid with
intent to defraud.
We will first describe one arrangement of our apparatus, and then proceed to set
forth a modification of the same, reference being made to the drawings left with
our Provisional Specification..
Figure 1 represents a section of a bottle neck made interiorly of cylindrical
shape.

page_text: A designates a circular groove provided in the cylindrical part of the bottle
neck.
Figure 2 represents a cylindrical tube B having at its upper part an inclined
plane C, this tube being traversed in proximity to the inclined plane by another
cylindrical tube E serving to receive a spring which has for its object to force the
two catches D outwards and fix them in the groove A, Figure 1, for retaining the
stopper in the neck.
•
At the lower end of the tube B is fixed a cone F pierced at its centre for
the passage of a rod G, around which are provided several openings for the outlet
of the liquid. At its upper extremity the rod G receives the valve H and at its
lower extremity is provided a ball I serving as a counterweight for lowering the
said valve.
The tube B, Figure 2, is provided on the outside with thin projections J of metal
or rings of cork or india-rubber surrounding the said tube for facilitating the
adhesion of the stopper to the interior periphery of the neck. This stopper may
be constructed of any other suitable material, more particularly of tin, as the latter
does not deteriorate and leaves no taste.
A stopper constructed in this manner is placed in the neck of the bottle as shown
in Figure 3.
In the modification represented in Figures 5 to 10 the stopper valve is con-
structed so as to enable the same to be easily returned to its seat either by means
of a metallic ball or by the action of the valve itself by augmenting its bulk or the
height of the fall. Moreover in the former arrangement we employ a cork stopper
for closing the bottle whilst in the second arrangement the groove A is nearer to
the orifice of the neck in which case we use a metallic screw-stopper in lieu of the
said cork stopper.
Figure 4 represents the said modification of the stopper in section through the
centre.
· Figure 5 shows a modification of the stopper valve which is slightly conical and
truncated.
Figure 6 illustrates a conical valve.
Figure 7 represents a valve with a metallic ball which can be displaced in a
conical lantern, the ball being shown in its upper position.
Figure 8 shows a truncated hollow valve with a metallic ball, these two parts
shown in their upper position being displaced in a truncated lantern.
Figure 9 represents the metallic screw stopper which we employ in lieu of the
cork stopper.
Figure 10 shows the same metallic screw-stopper without its screw-cap.
As shown in Figure 4, we place above the valve a a metallic ball b the weight
of which facilitates the return of the valve to its seat c. The valve and ball are
displaced in a lantern d which may be slightly conical and truncated or which may
be conical and have a rounded top as shown in Figure 7.
In the arrangement shown in Figures 5 and 6 the valve is truncated, it has a
certain bulk and falls easily back upon its seat as soon as the bottle is put upright
again.
In the arrangement illustrated in Figure 8 the lantern is truncated and has a
rounded top. It receives interiorly the valve which is likewise truncated and
provided with a rounded top, but this valve is hollow and receives a metallic ball.
The seat varies a little in this arrangement. It has a small projection upon
which the said valve fits; this projection may also be provided on the valve seat
in the other modifications.
The stopper e
is screwed with its lower part fupon the valve stopper. It forms
a kind of double stopper, being provided for transport with a cap g screwed on or
fixed by a bayonet joint, which is removed. A small screw cap arranged upon
the adjutage i serves for the outlet of the liquid. In the interior of the stopper is
a disc or a cross k having for its object to prevent the introduction of any

page_text: substance designed to deteriorate the apparatus. We may employ two crosses for
the same purpose.
Such is the principle of our improved stopper, but the details, forms, accessories,
materials and dimensions may be varied without departing from the nature of our
invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
First. The new kind of stopper adapting itself automatically by catches D or
spring projections in an interior groove A formed in the interior of the neck of the
bottle or receptacle, and preventing the introduction of another liquid into this
receptacle by the use of a valve with a counterweight.
Second. The application to our stopper apparatus for bottles, flasks and other
receptacles, of a valve falling automatically upon its seat by its own weight, as
shown in Figures 5 and 6.
Third. The application of a metallic ball acting by its weight either in the
interior of the valve shown in Figures 4 and 7 or in the interior of the valve
shown in Figure 8 for facilitating its expansion and ensure certain and rapid
obturation, the whole in principle substantially as described and represented.
