PROVISIONAL SPECIFICATION.
Improvements in or relating to the Stoppering of Bottles and
the like.
I, JOHN JONES of 17 Ravenscourt Park, Hammersmith, in the County of
Middlesex, Gentleman, do hereby declare the nature of this invention to be as
follows:
This invention relates to the stoppering of glass bottles and the like by which
I dispense with the rubber washers now commonly used with various stoppers and
at the same time obtain a ground glass joint.
In carrying the invention into effect I employ a movable glass stopper similar to
the ball stoppers commonly used for aerated drinks, but instead of being round it
is approximately cylindrical, but slightly tapered and having rounded ends, the
tapered portion being ground into the seating in the neck of the bottle. This
stopper travels in a suitably curved channel 'formed for it in the bottle so that when
it is desired to open the bottle the stopper is forced inwards and runs down this
channel out of the way and allows the escape of the contents of the bottle. If it
be desired to close the stopper again before all the contents have been discharged
this can easily be done by quickly tilting the bottle so as to allow the stopper to
slide down the channel back into its seat when the two surfaces being ground the
stopper will remain even when the pressure of gas inside the bottle has entirely
escaped.

Improvements in or relating to the Stoppering of Bottles and'
the like.
I, JOHN JONES, of 17 Ravenscourt Park Hammersmith, in the County of
Middlesex, Gentleman, 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 the stoppering of glass bottles, and the like by which
I dispense with the rubber washers now commonly used with various stoppers and
at the same time obtain a ground glass joint.
The word "bottle" as hereinafter used includes bottles and all other receptacles
of a like nature.
The invention will be best understood' by reference to the accompanying
drawings, in which
Fig. is a vertical section of the upper part of a bottle and a stopper
constructed according to this invention, the stopper here being shown in its closed
position.

page_text: Fig. 2 is a view similar to Fig. 1 with the stopper in its open position and the
bottle tilted for pouring out the contents, and
Fig. 3 is a section on the line 3-3 of Fig. 2.
Like letters indicate like parts throughout the drawings,
In carrying the invention into effect as shown in the accompanying drawings
1 employ a movable glass stopper A similar to the ball stoppers' commonly used for
aerated drinks, but instead of being spherical it is approximately cylindrical, but
slightly tapered as at A" and having rounded euds, the tapered portion A being
ground to fit the seating B' in the neck B2 of the bottle B this seating having its
larger end presented towards the interior of the bottle. This stopper A-travels in
a suitably curved channel CC (the part constituting a pocket) formed for it in
the bottle so that when it is desired to open the bottle the stopper A is forced
inwards and runs down this channel, and when the bottle for pouring out the
contents, is tilted towards the side at which the pocket C₁ is located, 'the stopper
enters said pocket so as to be out of the way and allows of the free escape of the
contents of the bottle. If it be desired to close the bottle again before all the
contents have been discharged this can easily, be done by quickly tilting the bottle
so as to allow the stopper A to slide out of the pocket down the,channel Cland
back into its seat B when, the surfaces of the neck Band stopper A being ground,
the stopper will remain in that position even when there is no pressure of gas inside
the bottle.

The channel C C is of such. diameter or sectional area throughout its length
that at no part of it can the stopper Albecome inverted oriturn end for end; the
stopper therefore always being in proper position, when the bottle is open, to
properly fit into its seating B.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is;-
1. In a device for stoppering bottles and the like wherein an internal movable
stopper is used the employment of a non-spherical stopper.
2. In a device for stoppering bottles and the like wherein an internal movable
stopper is used the employment of a stopper whose length is sufficient to prevent it
from turning end for end in the channel wherein it is free to rotate.
3. In a bottle or the like the combination with a taper seating with its larger
end presented towards the interior of a channel in direct communication with the
seating and a stopper adapted to fit into the seating and capable of moving in the
channel but prevented from turning end for end therein.
4. In a bottle or the like the combination with a taper seating with its larger
end presented towards the interior of a curved channel such as C C¹ in direct
communication with the seating aud a taper stopper such as A adapted to fit into
the seating and capable of moving in the channel but prevented from turning end
for end therein substantially as described and illustrated in the accompanying
drawings.
5. A bottle-stoppering device in which a taper stopper such as A is movable
within but prevented from leaving the bottle and closes the aperture by fitting into
a seating substantially as described and illustrated in the accompanying drawings.
6. The combination and arrangement of parts forming the complete device for
stoppering bottles and the like substantially as described and illustrated in the
accompanying drawings.
