PROVISIONAL SPECIFICATION.
Improvements in or relating to Valves for Stoppers of Bottles and
other Vessels.
I, CHRISTIAN HAMILTON GRAY, of The Indiarubber, Guttapercha, and Telegraph
Works Company Limited, of Silvertown, in the County of Essex, Indiarubber
Manufacturer, do hereby declare the nature of this invention to be as follows:-
-1
This invention relates to valves for stoppers of bottles and other vessels, the
principal object of the valve being to allow the bottle or vessel to be charged with
fluid under pressure, as in the case of aerated waters, the valve automatically closing
when the charging pipe or equivalent is withdrawn, and the stopper being perforated
for the reception of the charging tube.
In carrying out my invention I prefer to recess the inner end of the stopper and
in this recess to place a disc of any suitable shape-circular for example-of rubber
or other suitable material to form the valve and bear upon the bottom of the recess,
which would then form the valve seat.
may, be
The valve may be made of soft rubber and if desired, backed with hard rubber
or other material, or with metal, which if desired may be employed as a spring
to close the valve which may be secured in the recess in the stopper by an
opening in the wall surrounding the recess through which a tongue or portion of
the valve may be passed and secured. If the tongue be of soft rubber,
merely pulled into the hole in the wall, the contraction of the rubber when released
preventing it from afterwards escaping from the hole, but cement or other means
of securing the valve in the stopper may be employed if desired. The valve seating
is preferably conical, the valve resting upon the apex of the cone and if the pressure
be sufficient, then lapping round on the other portions of the cone.
More than one tongue may be employed if preferred and instead of making a hole
through the wall of the recess, an undercut or other opening may be employed in
which the tongue may be fastened as before or by special means such for example as
a wedge or the edge of the valve or the tongue may be secured by a rivet or other
means directly to the material of the stopper.

Improvements in or relating to Valves for Stoppers of Bottles and
other Vessels.
I, CHRISTIAN HAMILTON GRAY, of The Indiarubber, Guttapercha and Telegraph
Works Company Limited, of Silvertown, in the County of Essex, Indiarubber
Manufacturer, 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 valves for stoppers of bottles, and other vessels, the
principal object of the valve being to allow the bottle or vessel to be easily charged,
with fluid under pressure, as in the case of aerated waters, the valve automatically

perforated for the reception of the charging tube.
In carrying out my invention it is preferred to recess the inner end of the
stopper and in this recess to place a disc or piece of any suitable shape-circular for
example of rubber or other suitable material to form the valve and bear upon the
bottom of the recess, which would then form the valve-seat. The valve seating is
preferably conical, the valve resting upon the apex of the cone and if the pressure
be sufficient, then lapping round on the other portions of the cone.
In the accompanying drawings-
Figure 1 is a vertical central section of a perforated stopper fitted with an improved
valve according to this invention, the valve being in elevation;
Figure 2 is an underside view of the stopper shown in section in Figure 1 ;
Figure 3 is a plan of an alternative construction of valve;
Figure 4 is a view similar to Figure 1, of a stopper provided with a ball valve;
Figure 5 is another view similar to Figure 1 of a stopper provided with a hinged
flap valve.
Like letters indicate like parts throughout the drawings.
With reference first to Figures 1 and 2, A is the body of the stopper, in which is a
central charging-passage B; the central passage has a flared or bell-mouthed outer
end C to facilitate the entrance of the charging pipe into it. A' is a ring of soft
rubber or other packing material encircling the neck of the stopper as is customary.
At the lower or inner end of the stopper is a recess D containing the valve E, the
recess being so shaped that a rim A2, preferably coned as shown and constituting
an annular valve-seating, is provided at the lower end of the charging-passage B.
The valve E is secured in the recess D by a tongue or projection E¹ extending from
the valve into a counter-sunk or other suitable hole or cavity as at D³, in the wall
of the recess D.
The valve may be made of soft rubber, and if desired, be backed with hard
rubber or other material or with metal. If the tongue E' be of soft rubber, as is
convenient, it may be merely pulled or pushed into the cavity D2, the expansion of
the rubber into the hollow preventing it from afterwards escaping therefrom; but
cement or other means for securing the valve in the stopper may be employed
if desired.
In the alternative construction of valve illustrated in Figure 3 there are two
tongues or extensions E' which are similarly secured in two recesses appropriately
situated in the wall of the recess D.
In the stopper illustrated in Figure 4 the valve E is spherical and provided with
an extension E', which, where it joins the sphere is flexible, the latter being preferably
made of india-rubber for instance; whilst the extension normally keeps the sphere E¹
on its seating so as to close the lower end of the passage B, it will permit the sphere
to be thrust downward away therefrom by the charging pipe when required; on the
extension E is a shoulder E2 to prevent it from going too far into the hole D², the
outer end E³ of the extension having an external enlargement to keep it in place.
In the modification illustrated in Figure 5 the valve is in two parts, one part E
being soft material such as indiarubber secured upon a harder backing E, the
latter being for instance of ebonite; the wall at one side of the recess D is notched
as at F to receive the part E5 of the valve through which a pin G is passed to
secure the valve in place; the valve turns about this pin as about a hinge.
Instead of securing the valves in place by the devices bereinbefore explained they
may be secured by a rivet passed through them into the material of the stopper at one
side of the valve, or may be otherwise retained in position as desired. A metal or
other spring may be employed to close the valve.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. In a perforated bottle-stopper or the like of the kind described having an

page_text: opening to receive a charging tube, a non-return valve arranged and operating
substantially as and for the purpose specified.
2. In a perforated bottle-stopper or the like of the kind described in Claim 1
a non-return valve connected to it by a hinged or flexible connection such as E¹
substantially as and for the purpose specified.
3. In a bottle-stopper or the like the non-return valve substantially as and for the
purpose described and illustrated in Figures 1 and 2 or Figure 3 or Figure 4 or
Figure 5 of the accompanying drawings.
