PROVISIONAL SPECIFICATION.
Improvements in Bottle Stoppers for Gaseous Beverages.
We, HAMILTON BREAR of 9 Broom Close, Ginger Beer Manufacturer, and
JOHN DRAKE of 30 Newbould Road, Brightside Lane, Engineer, both in the
City of Sheffield, do hereby declare the nature of this invention to be as
follows:-
This invention is for improvements in screw stoppers and other like fastening
stoppers for bottles, to enable the bottles to be filled with hop-bitters, aerated stone
beer, and similar gaseous beverages while under pressure, and which will close
automatically.
We prefer to use the form of the ordinary composition screw stopper, with a
milled head, but we do not confine ourselves to such stopper.
We make a hole through it longitudinally, which when the stopper is in position,
will give communication from the outside to the inside of the bottle, and a shoulder
is formed by reducing the hole at a short distance from the screw end.
A valve pin fits freely in this longitudinal opening having a head at its outer end,
and a rubber plate upon its inner end to form a valve, which bears upon the end of
the screw part and closes the opening.
It is pressed against it by the action of a coiled spring placed round the valve
pin and bearing against the shoulder beforenamed in the hole through the stopper,
and also against the head of the pin.
When the stopper is in position, and the bottle is placed in the filling machine,
the pressure of the liquid lifts the valve and fills the bottle, and the instant such
pressure is removed the valve closes and prevents the escape of either gas or
liquid.
In some cases the enring may be dispensed with:

Improvements in Bottle Stoppers for Gaseous Beverages.
We HAMILTON BREAR, of 9 Broom Close, Ginger Beer Manufacturer, and
JOHN DRAKE of 30 Newbould Road, Brightside Lane, Engineer, both in the
City of Sheffield 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 improvements in screw stoppers, and other like stoppers
for bottles, the object being to enable the bottle to be filled with a gascous
beverage, (and more particularly hop bitters) while the stopper is in the bottle, and
which will automatically close so as to prevent escape.
The construction of the improved stopper is shown in the annexed sheet of
drawings, in which
Fig. 1. is a section of a screw stopper showing the valve.

page_text: We prefer to use a stopper of the form of the ordinary composition screw stopper
with a milled head, such as shown in Fig. 1, but we do not confine ourselves to this
form.
We take such a stopper and make a hole through it longitudinally, this hole A,
is made smaller at the end which enter the bottle, thus forming a shoulder at the
junction of the two diameters as shown.
A valve pin B, fits freely in this longitudinal hole, having a head at its outer.
end, and a neck at its inner end, upon which is placed a rubber washer or disc C,
which forms the valve, and which bears upon the end of the stopper and closes the
opening.
It is pressed against the stopper by the action of a coiled spring D, placed
round the pin B, and bearing against the shoulder before mentioned, and the head
of pin.
Thus when the stopper is screwed into the bottle, and the bottle placed in the
filling machine, the liquid under pressure will lift the valve and fill the bottle, and
the moment the pressure is removed the valve closes and is kept closed by the
gaseous pressure within..
The bead of the pin B, is made of such a form that it will readily permit the
liquid to pass it, and in some cases we dispense with the coiled spring D, and rely
entirely upon the action of the gas within the bottle.
We may also substitute a ball valve E, for the one previously described, in which
case we prefer to construct a seating. F,,of rubber, or vice versa, the ball of rubber
and the seat of hard material:
One or more passages either as round holes, or as slots or saw gates may be used
as may be found preferable, and instead of a ball, an elongated form of valve may
be used.
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. A screw stopper for bottles, provided with a valve that will permit the bottle
to be filled with gaseous liquid through a central opening, and will automatically
close when the bottle is full, or the pressure removed from the outside, substantially
as described and shown.
2. A stopper for bottles, which when in position will permit liquid under gaseous
pressure to enter the bottle through a valve, the said valve closing so as to prevent
escape of liquid when outside pressure is removed, substantially as herein before
described, with reference to the drawings.
