page_text: We, CLARA BLAKEMORE, of 7, Prescot Street, New Brighton, Cheshire, and
JAMES CHANDLER, of 129, Field Street, Liverpool, Mechanical Engineer, do
hereby declare the nature of this invention to be as follows:-
A bottle stopper according to this invention has for its object the prevention of
the liability of bottles charged with aerated and other liquids to burst, and also to
provide a more easy means of opening said bottles.
In order to effect the above objects we provide the bottle stopper with a valve,
which is adapted to relieve pressure within the bottle.
Such valve may be arranged to be opened by the pressure within the bottle, or
by manipulation outside of the bottle, or both.
The valve may be arranged in various ways. Thus a central passage through
the stopper may be controlled by a valve on the outward end of the stopper, said.
valve being provided with a spindle passing through said passage and adapted to
close against pressure within the bottle by means of a spring. Such valve will
relieve excessive pressure within the bottle, and also, by mechanically lifting it,
will exhaust the pressure within the bottle, as for instance when it is desired to open
the bottle. For the latter purpose the valve may be provided with a projection to
enable it to be taken hold of. Or the valve may consist of a flat spring secured to
the stopper and adapted to lay over the outer orifice of the central passage in the
stopper. Or the central passage in the stopper may be closed by two balls of
india-rubber connected together by a strand of the same material passing through
the passage, the outward ball acting as the valve, in which case the central passage
would be provided with branch passages at its inner end; or the inner ball may
have passages formed in it, or may be dispensed with and the strand otherwise
suitably secured.
In a modification the valve may control the inner end of the passage through the
stopper and be adapted to be opened by depression from the outside.
It will be understood that the materials of which the stopper, valve, and spring,
may be composed may be varied to suit various requirements.

page_text: Improvements in Bottle Stoppers.
We, CLARA BLAKEMORE, of 7, Prescot Street, New Brighton, Cheshire, and
JAMES CHANDLER, of 129, Field Street, Liverpool, Mechanical 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:-
A bottle stopper according to this invention has for its object to prevent bottles
charged with aerated or other liquids from exploding, and also to provide a more
easy means of opening such bottles.
In order to effect the above objects we provide the bottle stopper with a valve,
which is adapted to relieve pressure within the bottle.
Such valve may be arranged to be opened by the pressure within the bottle, or
by manipulation outside of the bottle, or both."
Various ways of arranging such a valve are shewn in the accompanying
drawings.
Figure 1. A central passage a through the stopper b is controlled by the valve c
on the outward end of the stopper, such valve being provided with a spindle d,
disposed in the passage a, and adapted to close against pressure within the bottle
by means of the spring e. Such a valve will relieve excessive pressure within the
bottle, and also, by mechanically lifting it, will exhaust the pressure within the bottle,
as for instance when it is desired to open the bottle. For the latter purpose the
valve is provided with, a projection f to enable it to be taken hold of.
-
The type of stopper shewn in the drawings is that of the ordinary internal
stopper, 9 being the rubber washer, and the leaden sinker, which latter is of ring
form, surrounding-but not in contact with-the central passage a.
Figure 2. In this case the valve c controls the inner end of the passage a, and is
closed by the pressure within the bottle. To open the valve and relieve such
pressure, so that the stopper may be easily pushed into the bottle, the button i on
the spindle d is depressed by the finger.
Figure 3. The central passage a is closed by one of two balls of india rubber k, l,
connected together by a strand m of the same material passing through the
passage a. The ball k forms the valve, and in order that the inner ball I may not
obstruct the passage a, branch passages al are formed in the base of the stopper, as
shewn, or the inner ball may itself be perforated. In some cases the inner ball
may be dispensed with and the inner end of the strand m is nipped, sealed, or
otherwise attached to the base of the stopper.
Figure 4. The valve c here consists of a flat spring laying over the outer orifice
of the passage a, and secured to the stopper by a spike n. This valve relieves
excessive internal pressure and may also be raised by the finger when it is desired
to open the bottle.
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. An internal stopper penetrated by a passage a, and a valve c caused to
control the outer orifice of said passage, against internal pressure, by a spring e,
substantially as and for the purposes described with reference to Figure 1 of the
drawings.
2. An internal stopper penetrated by a passage a, a valve c caused to control the
inner orifice of said passage by the internal pressure of the bottle contents, and a
spindle d and button i connected with said valve, whereby the internal pressure of

page_text: the bottle may be relieved previously to opening the bottle, substantially as set
forth with reference to Figure 2 of the drawings.
3. An internal stopper penetrated by a passage a, and a valve k caused to
control the outer orifice of said passage, against internal pressure, by a rubber
strand m, connected to a ball or otherwise attached to the base of the stopper b,
constructed and operating substantially as and for the purposes herein described and
as shewn in Figure 3 of the drawings.
4. An internal stopper penetrated by a passage a, the outer orifice of which is
controlled against internal pressure by a flat spring c attached to the head of such
stopper, substantially as set forth with reference to Figure 4 of the drawings.
