PROVISIONAL SPECIFICATION.
An Improved Stopper for Internally Stoppered Bottles.
I, JOSEPH RICHARDSON of 160 Church Street, North Shields, in the County of
Northumberland, Salvage Contractor, do hereby declare the nature of this invention
to be as follows:-
My invention consists of a stopper which can be adapted in shape to suit the mouth
of any bottle without special elastic or other fitting within the mouth and which will
allow the pressure of gas or air within the bottle to be relieved before the stopper
leaves the neck and the contents to be poured out without waste.
The stopper may be made of any suitable material but I prefer wood and is tapered
and fitted with an India rubber jacket a little larger in diameter than the wood and
the larger end, which is the inner end, is formed with a cavity fitted with an India
rubber washer which forms the seat for a small valve on the end of a spindle which
passes through a hole in centre of the stopper and terminates outside with a button.
The hole in stopper is round and the spindle triangular in section so that spaces are
left between it and the hole by which the gas or air escape when the valve is opened
by the top button being pressed down by the finger on top of stopper in which
grooves are provided to leave an outlet for the gas or air beneath the button.
The pressure of gas or air being thus relieved the stopper falls into the bottle and
the contents flow freely out without an explosive charge of the gas or air and when
the bottle is to be refilled the stopper falls down into its proper position in mouth of
bottle and the pressure of gas or air closes the valve.
No force is necessary nor is any implement required to force the stopper from its
seat with risk of breaking the bottle neck.

An Improved Stopper for Internally Stoppered Bottles.
1, JOSEPH RICHARDSON of 160) Church Street North Shields, in the County of
Northumberland, Salvage Contractor, 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 consists of a stopper which can be adapted in shape to suit the mouth
of any bottle without special elastic or other fitting within the mouth and which will
allow the pressure of gas or air within the bottle to be relieved before the stopper
leaves the neck and the contents to be poured out without waste.
The stopper may be made of any suitable material, but I prefer wood, and is
tapered and fitted with an Indiarubber jacket a little larger in diameter than the
wood and the larger end, which is the inner end, is formed with a
cavity fitted
with an India rubber washer which forms the seat for a small valve on the end of a
spindle which passes through a hole in centre of the stopper and terminates with a
bution.
The hole in stopper is round and the spindle triangular in section so that spaces are
left between it and the hole, by which the gas or air escapes when the valve is opened
by the top button being pressed down by the finger on top of stopper in which
grooves are provided to leave an outlet for the gas or air beneath the button.
The pressure of gas or air being thus relieved the stopper falls into the bottle and
the contents flow freely out, without an explosive charge of the gas or air, and when
the bottle is to be refilled the stopper falls down into its proper position in mouth of
bottle and the pressure of gas or air closes the valve, or a spring or other elastic
fitting may be applied which will close the valve immediately the finger is removed.
No force is necessary nor is any implement required to force the stopper from its seat
with risk of breaking the bottle neck.
The accompanying sheet of drawings illustrates my invention as I propose to carry
it into practice but it will be apparent that the form of the stopper itself, as also the
details of the relieving valve, may be varied.
Fig. 1 shews a stopper in position in the mouth of an ordinary bottle for aerated
liquids of its natural size.
Fig. 2 shews a stopper twice the natural size for clearness of the parts and Fig. 5 a
plan in section through of Fig. 2.
Fig. 4 is another view of stopper looking at right angles to Fig. 2, and with the
valve shewn open, and Fig. 5 is a plan in section through of Fig. 4.
A is the body of stopper fitted with an India rubber jacket or washer B to make an
air and water tight closing of the bottle. is the relieving valve with a triangular
spindle D passing through a round hole E in the stopper and fitted at top with a

page_text: button F for the finger, the valve being kept closed against an India rubber seat G let
into bottom of stopper, by an elastic spring of India rubber H under the button
until pressed down and opened by the finger. The slots K K across upper end of the
stopper allow the gas or air to escape, the arrows on Figs. 4 and 5 indicating its
course when the valve is opened. The button F is always below the mouth of the
bottle so that there is no danger of the valve being opened by accident. The
immediate result of the valve being pressed down and the gas or air escaping is the
fall of the stopper into the bottle without any explosive discharge of the contents.
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 :-
First. The improved stopper adapted to close the mouth of any bottle-without
special formation or fitting therein-by means of an elastic jacket or washer and
fitted with a valve which, being opened, allows a portion of the contained gas or
compressed air to escape when, the stopper falling into the bottle the contents can be
poured out without explosion and waste substantially as described and illustrated.
Second. The application to any internal stopper, to which it is applicable, of a valve
for the purposes above set forth thus forming an improved stopper according to my
invention substantially as described and shewn.
