PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Bottles and Jars.
I, CARL RUDOLPH GUSTAV HÖVERMANN, of No. 3, Lüneburgerstrasse, Hamburg,
in the German Empire, Engineer, do hereby declare the nature of this
invention to be as follows;
-
The present invention relates to improvements in stoppers for bottles and jars
and more especially to such stoppers designed to serve as outlet for the contents
of the vessel; the outlet being kept closed by a sort of valve integral with the
stopper; and the object of this invention is to provide means for securing the
outlet valve as well as the bottle stopper by means of one and the same device
to the mouth of the bottle or jar.
The outlet valve forming part of the bottle stopper is pressed against from below
by an elastic tightening ring or seat lodged in the mouth of the bottle, not only
by the pressure of the gas within the latter but also by lateral bars, which engage
within suitable recesses under a shoulder at the upper end of the stopper, whereby
an absolutely tight closure of the bottle is effected.
In this position of the stopper a bow provided for connecting the lateral bars,
bears against another shoulder of the stopper in such a manner that a lifting of the
latter on increased pressure of the gas within the receptacle is prevented. In this
position the stopper acts as an ordinary bottle stopper, outwardly connected to the
mouth of the receptacle by means of a lever and pivots. The lever by means of
which the lateral rods are pushed on the upward motion of the lever against the
first-named shoulder is at the position of rest and secured in this position on the
one hand by reason of the said pivots of the lateral rods having passed the line of
pressure between the working point and the fulcrum of the lever, and on the other
hand, by the spring action of the latter. By this means an accidental opening
of the bottle-stopper is entirely prevented.
The opening of the bottle or jar for the purpose of emptying the latter is
effected by actuating the said lever whereby the latter is caused to swing down-
wards and to occupy a more horizontal position. In this position the valve is still
kept closed, the upper ends of the lateral rods freely moving within vertical notches
in the stopper, thus admitting the lever to occupy a convenient position for its
further actuation. On proceeding with the turning of the lever, the stopper is
further drawn into the bottle mouth and thereby the valve lowered from its seat
so that the contents of the bottle or jar may be discharged by tilting it in the
ordinary manner.

I, CARL RUDOLPH GUSTAV HÖVERMANN, of No. 3, Lüneburgerstrasse, Hamburg,
in the German Empire, Engineer, 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 improvements in stoppers for bottles and jars and more
especially to such stoppers designed to serve also as outlet for the contents of the
vessel; the outlet being kept closed by a sort of valve integral with the stopper;
and the object of this invention is to provide means for securing the outlet valve
as well as the bottle stopper, by means of one and the same device, to the mouth
of the bottle or jar.
I attain this object by means of the mechanism particularly described herein-
after with reference to the accompanying drawing, in which;
-
Fig. 1, is a vertical section of my improved stopper as affixed to the mouth of an
ordinary bottle, showing the outlet valve in closed position;
Figure 2, a side elevation of the same;
Figure 3, a vertical section at right angles to Figure 1 but showing the position
of parts in the state when the outlet valve is open, and
Figure 4, is a top view of Figure 2.
Similar letters refer to similar parts throughout the several views.
The outlet valve b, forming part of the bottle stopper a, in the position illus-
trated by Figures 1 and 2, is pressed upwards against the elastic tightening ring
or seat c lodged in the mouth of the bottle, not only from below by the pressure
of the gas within the latter but also by the lateral bars f, the upper end of which
engage suitable recesses under the projection or shoulder g at the upper end of
the stopper, whereby an absolutely tight closure of the bottle is effected.
In this position of the stopper the bow f¹, provided for connecting the lateral
bars f, bears against another projection or shoulder a¹ of the stopper a in such a
manner, that a lifting of the latter on increased pressure of the gas within the
receptacle is prevented. In this position the stopper acts as an ordinary bottle
stopper, outwardly connected to the mouth of the receptacle by means of the lever e
and the pivots 1. The lever e, by means of which the lateral rods f are pushed
on the upward motion of the lever against the shoulder g, is at the position of rest
and secured in this position on the one hand by reason of the pivots 7 of the lateral
rods having passed the line of pressure between the working point and the fulcrum
of the lever e, and on the other hand, by the spring action of the latter. By this
means an accidental opening of the bottle stopper is entirely prevented.
As will be seen, the stopper is provided with a central bore communicating with
the interior of the vessel.
The opening of the bottle or jar for the purpose of emptying the latter is effected
by actuating the lever e whereby the latter is caused to swing downwards and to
occupy the position illustrated by dotted lines, Figure 3. In this position the
valve is still kept closed, the upper ends of the lateral rods f freely moving
within the vertical notches as of the stopper a, thus admitting the lever e to occupy
a convenient position for its further actuation. On proceeding with the turning
of the lever e by means of the thumb the stopper is further drawn into the bottle
mouth and thereby the valve b is lowered from its seat c so that the contents of
the bottle or jar may be discharged by tilting the same in the ordinary manner.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;.
-
The combination with a stopper for bottles and jars, provided with a central
bore designed to communicate when in its open position with the interior of the
vessel, and a valve forming the lower part of the stopper and designed to bear from
below against a valve seat secured in the neck of the vessel, of a locking device,
consisting of a hand-operated lever having its fulcrum on the vessel, lateral rods
connected to the lever and bearing against a shoulder of the stopper, and a bow
bearing against another shoulder of the stopper, all connected and actuating sub-
stantially as set forth.
