PROVISIONAL SPECIFICATION.
An Improved Bottle Stopper.
We, CHARLES WARREN, of 101, Hungerford Road, Camden Town, in the
County of London, Mechanical Expert and ERNEST CROSSLEY KNIGHT, of
Oxford Road, Guiseley, near Leeds, in the County of Yorks, Commission Agent,
do hereby declare the nature of this invention to be as follows:-
.
This invention relates to bottle stoppers of the kind provided with a nozzle or
spout through which the liquid is discharged and with a tube within or connected
with such nozzle or spout through which air enters the vessel as the liquid is
discharged.
According to our invention we provide for closing the mouth of such spout and of
the air tube in the following manner, that is to say, we pivot upon the spout a
weighted lever carrying a pivotted cap designed to be held by the lever over the
mouth of the spout during the time that the bottle to which the stopper is applied
is in an upright position. When, however, the said bottle is tipped the weight
causes the cap to be moved away from the spout so that the liquid can be
discharged.
To prevent the cap from becoming displaced relatively with the mouth of the
spout we arrange a horn or projection against which when the stopper is tipped the
cap impinges the said horn or projection also serving to cause the tilting of the cap
in such a manner that the liquid discharged from the spout will not come into
contact with the said cap.

COMPLETE SPECIFICATION.
An Improved Bottle Stopper.
We, CHARLES WARREN, of 101, Hungerford Road, Camden Town, in the
County of London, Mechanical Expert, and ERNEST CROSSLEY KNIGHT, of
Oxford Road, Guiseley, near Leeds, in the County of Yorks, Commission Agent,
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 of. the kind provided with a nozzle or
spout through which the liquid is discharged and with a tube within or connected
with such nozzle or spout through which air enters the vessel as the liquid is
discharged.
According to our invention we provide for closing the mouth of such spout and
of the air-tube in the following manner, that is to say, we pivot upon the spout a
weighted lever carrying a pivoted cap designed to be held by the lever over the
mouth of the spout during the time that the bottle to which the stopper is applied
is in an upright position. When, however, the said bottle is tipped the weight
causes the cap to be moved away from the spout so that the liquid can be
discharged.
To prevent the cap from becoming displaced relatively with the mouth of the
spout we arrange a horn or projection against which, when the stopper is tipped, the
cap impinges, the said horn or projection also serving to cause the tilting of the cap
ГР.

page_text: in such a manner that the liquid discharged from the spout will not come into
contact with the said cap.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figures 1, 2 and 3 are respectively a side elevation, a front elevation and a plan
of our improved bottle stopper :
section on the line 4-4, Figure 2:
Figure 4 is
Figure 5 is a view similar to Figure 4 shewing the position of the parts when the
stopper is tilted.
a is the cork or stopper adapted to be introduced into the mouth of the bottle
to which the stopper is applied. b is the pipe forming the discharge spout, and
c is the pipe or tube-inserted within the spout 6 and serving to permit the entrance
of air into the bottle as the liquid is discharged therefrom. d is a double armed
lever pivotted upon the projection e on the spout and carrying at one end a
weight and at the other end the pivotted cap 9 which serves to close the mouth of
the spout. In practice the lever d is made double, as shewn most clearly in
Figures 2 and 3, the two sides being connected at the lower end by the weight f
and at the upper end by the pin h forming the pivot of the cap g. i is the horn
formed upon the spout and serving to limit the movement of the cap g.
When the bottle to which the spout is applied is in an upright position, as shewn
in Figure 4, it is obvious that the gravity of the weight will hold the cap g in
close contact with the spout b, the mouth of the spout and the adjacent surface of
the cap being properly faced so as to form an air-tight joint. When, however, the
stopper is tilted, for instance to the position shewn in Figure 5, the gravity of the
weight tends to move the lever-arm carrying the cap g in the direction of the arrow
Figure 5, whereby the said cap g is moved away from the mouth of the spout band,
owing to its contact with the horn i, takes the position shewn in Figure 5. Our
improved stopper is not only very advantageously employed for bottles containing
spirits and other liquids which readily evaporate, but possesses the further important
advantage that it can be used on bottles containing aërated or other liquids under
pressure, this being chiefly due to the fact that any pressure within the bottle acts
upon the cap g in direction of the arrow 1, Figure 4, whilst to move the cap away
from the mouth of the spout it would be necessary for the pressure to act in the
direction of the arrow 2, Figure 4.
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
1. In a bottle-stopper having a discharge spout of the kind hereinbefore described,
the combination with the said spout of a cap carried by a lever provided with a
weight designed when the stopper is in a vertical position to hold the said cap in
contact with the mouth of the spout, substantially as described.
2. In a bottle-stopper having a spout and a cap designed to close the said spout
and carried by a weighted lever, a horn such as i for limiting the movement of the
said cap, substantially as described.
