Improvements in Bottle Stoppers.
I, BERNARD DREYFUSS, of 7 East 46th Street, in the City, County and State
of New York, United States of America, Manufacturer, 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:---
My invention relates to that class of stoppers which are used for bottles which it
is desired to re-fill after having been once emptied of their contents, and by means
of which a bottle may be closed so as to becamo air tight, and more particularly,
to that kind of stoppers in which an elastic material is combined with a more solid
substance to close the aperture of the bottle.
I am aware that there have been a number of devices for this purpose but most
of them are open to the objection that the elastic packing is so arranged as to be
worn out speedily or that a large surface of rubber is presented to the fluid and is
liable to affect its taste. My invention reduces the exposed surface to a minimum
and at the same time the rubber affords a certain and durable packing.
To accomplish this I make a solid stopper, preferably of porcelain, and provide
it with an elastic ring or packing at its lower end. This stopper is fastened to the
bottle by means of a wire passing through the solid portion of the stopper and
connected with any of the well known lever devices by means of which it is pressed
firmly into the neck of the bottle.
In the drawing
Fig. 1 shows a side view of my stopper in which A is the body of the stopper,
provided with the cone shaped lower end K which terminates in the button C.
B is the rubber ring which is slipped over the end and fits into the recess which
forms the cone point. The interior surface of the rubber ring is shaped to
correspond to the surface of K. O is the opening through which the wire H.
passes, by means of which the entire stopper is pressed down into the opening of
the bottle.
Fig. 2 is a cross section of Fig. 1 at 2-2 and shows the same parts. A'indicates
the inner corner of the recess in the porcelain head into which the ring B fits, and
I is the recess in the ring into which the neck of the bottle fits.
Fig. 3 shows a modification O' of the opening for the wire in which the ellipse
is placed transversely to the stopper and a depression E provides a means by
which the wire H is brought to and retained in the centre of the stopper.
Fig. 4 shows another form of opening in which the opening is a curve through
the porcelain. The opening O2 is but a little higher than the diameter of the bail
wire and the curve as shown in Fig. 7 is constructed so that the bent end of the wire
can be passed through. The porcelain is cut away at D to prevent its chipping
from the pressure of the wire.
Fig. 5 is a cross section of Fig. 4 at 5-5. and Fig. 7 is a cross section of the
same figure at 6-6. The dotted line in Fig. 7 shows the direction of the bail
wire when in position, having the contact points G, G and F.
Fig. 6 is a view of the rubber packing B.
Fig. 8 shows another form of opening O3 which is an exact half circle, the
upper part being wide enough to admit the bent end of a bail wire.
Figures 9 and 10 are a view and cross section of a modified form of packing B',
to which the shape of the porcelain is adapted. This can be used with either form
of opening.
In all figures like letters represent like parts.

page_text: The action of my invention is simple. As the wire mechanism presses the
stopper into the neck of the bottle, the rim of the bottle opening fits into the
recess of the rubber ring B, and with the lower part of the rubber completely
closes the opening of the bottle. It will be seen that there is no considerable
friction on the portion of the ring which presses against the rim of the bottle_but
only a direct pressure, so that there is little or no wear on the rubber, and at
the same time the porcelain button so nearly covers the bottom of the ring that
only the narrow strip around it will be brought into contact with the fluid. In the
practice of my invention I use the form of rubber shown in Figures 9 and 10 for
bottling fluids having the greatest amount of gas and exerting the greatest pressure,
as the effect of the pressure of the bottle rim on the rubber is to draw down the
outer circumference of B' so that it closes the opening most absolutely.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A bottle stopper having a solid body adapted to receive a fastening wire and
provided with a conical bearing below a recessed shoulder adapted to receive an
elastic packing above a button suitable for retaining such packing in place,
substantially as described.
2. A bottle stopper, having a solid portion provided with an opening adapted to
admit the bent end of a bail wire; such solid portion having a recessed shoulder
adapted to receive an elastic packing arranged upon a conical bearing and retained
in position by a button placed below the packing and made integral with the said
solid portion, substantially as described.
3. The combination in a bottle stopper of a solid body provided with means for
holding a fastening wire, a conical bearing below a recessed shoulder on said solid
portion, a rubber packing having a shoulder arranged above the cylindrical portion
of such packing and adapted to enter the neck of a bottle, and button on said
conical bearing made integral with it, and adapted to retain said packing in
position, substantially as described.
4. The combination in a bottle stopper of a solid head provided with a curved or
circular opening substantially as described adapted to admit the bent end of a
fastening wire, a solid bearing below such head adapted to receive a rubber
packing, a rubber packing arranged upon said bearing and having a recessed
shoulder above a cylindrical or conical portion, such portion being adapted to enter
a bottle neck, and the shoulder being arranged to press upon the rim of such bottle,
and a button made integral upon said solid portion and adapted to retain said
packing in position, all substantially as described.
