PROVISIONAL SPECIFICATION.
Improvements connected with Bottles and other Necked Vessels, and
in Appliances for Closing same and Regulating the Pouring of
the Contents from such Vessels.
I, Alfred CooPER, of Belgrave Terrace, Lambeth, Surrey, Carriers Agent,
do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in bottles and other necked vessels
and in the apparatus for stoppering and regulating the withdrawal of their contents,
this being mainly effected and controlled by screw action, and when there is gas
pressure or a charge of vapour, scent &c. without lessening it, or admitting air,
except proportionately as the contents decrease.
In applying my invention to the ordinary ginger beer, or lemonade bottle where
the joint is of the ordinary plug and elastic, or globe and elastic kind made tight
by internal gas pressure, the plug is made long enough to project somewhat above
the bottle top, the globe stoppers being made with a shaft or plug end, and the
upper part of the plug has a screw thread formed on it.
After the bottle has been filled and the joint made in the ordinary way, what I call
a controller or fulcrum ring or collar bored in the centre and screw threaded inside
and out, or at two parts of its inside, is screwed down upon the plug until it reaches
the bottle top to which its outer thread also screws, a threading being there provided
for the purpose, and as the controller goes further down the plug it finally reaches
the end of the bottle top thread and by screwing hard up is tightly fixed there. An
abutment or fulcrum is thus obtained, by means of which, the plug can be screwed
up or down and the joint formed with non pressure liquors, or if already formed by
gas pressure, it can be tightened or slackened by siezing the top of the plug with
the fingers, or otherwise, and turning it.
The top of the plug is flattened to give a better hold to the fingers, and holes are
made, through which, if preferred, a headed pin, or a lever can be passed, by turning
which a joint of exceeding tightness is quickly obtained, which can be thus opened,
or closed again with facility.
When the controller ring or collar is thus screwed on and the plug screwed up,
so as to make the joint of the required tightness, the bottle is ready to send out, or
store away. The screw threads on the outside and the inside of the ring or collar
are of the same pitch so as to operate upon the plug and bottle top simultaneously.
Opening is effected by back turning the plug, which will thus open the joint by
screw action, force the plug inwards gradually, and the bottle being partially
inverted, as usual, let all, or any part of the contents out at an opening provided in the
bottle neck between the joint at the shoulder of the bottle, or elsewhere, and the
controller collar. At any time during the discharge returning the plug will cut off
the discharge and re-make the gas-tight joint as before.
During the discharge of as much of the contents, as may be desired, the gas &c.
would remain in the upper part of the now inverted bottle, and would not be
discharged, or its pungency wasted, while successive intermittent draughts were
drawn until but little liquor remained in the bottle, and thus by this means real
screw control" and genuine "intermittent discharge " are obtained, the opening is
rendered easy and quiet, this being effected quickly by screw action, waste and
splashing avoided, while the bottle can be screwed up again when empty, and so
kept clean and sweet.
66
Instead of the discharge being made from the side of the bottle neck, the controller
collar can be made larger and higher, and in cap form and screwed on to a thread
at the bottle top, and the exit be made from the bottle top into a chamber in the

page_text: cap, and thence from an opening in the side of the cap, the plug turning in a thread
in the centre of the cap, and the joint being made at the shoulder or against a rim
near the bottle top.
The plug is made much smaller below its threaded part, and above the head, than
the bore of the bottle neck, so as to allow the liquor to pass out quickly opposite the
exit opening in the side of the neck of the bottle, a hole is made to admit air to
facilitate the discharge, and the same thing is done in the cap form of controller.
The opening in the cap for discharging the contents can be prolonged in the form of
a nozzle of any desired length or form, and that in the bottle neck can be treated
similarly. The nozzle can also in some cases be made large enough to act as a
measure, and terminate in a tap.
Sometimes when cork is used instead of elastic to make the joint, a groove is
made in the plug just above the cork, and a rubber ring is fitted into the groove, so
as to press down the cork as the plug is screwed downwards.

COMPLETE SPECIFICATION.
Improvements connected with Bottles and other Necked Vessels, and
in Appliances for Closing same and Regulating the Pouring of
the Contents from such Vessels.
I, ALFRED COOPER, of Belgrave Terrace, Lambeth, Surrey, Carriers Agent,
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 relates to certain improvements in bottles and other necked vessels
and in the apparatus for stoppering and regulating the withdrawal of their contents,
this being mainly effected and controlled by screw action, and when there is gas
pressure or a charge of vapour, scent &c. without lessening it, or admitting air,
except proportionately as the contents decrease.
In applying my invention to the ordinary ginger beer, or lemonade bottle where
the joint is of the ordinary plug and elastic, or globe and elastic kind made tight by
internal gas pressure, the plug is made long enough to project somewhat above the
bottle top, the globe stoppers being made with a shaft or plug end, and the upper
part of the plug has a screw thread formed on it.
After the bottle has been filled and the joint made in the ordinary way, what I
call a controller, or fulcrum ring, or collar bored in the centre and screw threaded
inside and out, or at two parts of its inside, is screwed down upon the plug until it
reaches the bottle top to which its outer thread also screws, a threading being there
provided for the purpose, and as the controller goes further down the plug it finally
reaches the end of the bottle top thread and by screwing hard up is tightly fixed
there. An abutment or fulcrum is thus obtained, by means of which, the plug can
be screwed up and the joint formed with non pressure liquors, or if already formed
by gas pressure, it can be tightened, or slackened by siezing the top of the plug
with the fingers, or otherwise, and turning it.
The top of the plug is flattened to give a better hold to the fingers, and holes
are made, through which, if preferred, a headed pin, or a lever can be passed, by
turning which, a joint of exceeding tightness is quickly obtained, which can be thus
opened, or closed again with facility.
When the controller ring, or collar is thus screwed on and in the case of non-
pressure liquids the plug screwed up, so as to make the joint of the required
tightness, the bottle is ready to send out, or store away. The screw threads or

page_text: the outside and the inside of the ring, or collar are of the same pitch, so as to
operate upon the plug and bottle top simultaneously.
Opening is effected by back turning the plug, which will thus open the joint
by screw action, force the plug inwards gradually, and the bottle being partially
inverted, as usual, let all, or any part of the contents out at an opening provided
in the bottle neck between the joint at the shoulder of the bottle, or elsewhere,
and the controller collar. At any time during the discharge returning the plug
will cut off the discharge and re-make the gas tight joint as before.
During the discharge of as much of the contents, as may be desired, the gas &c.
would remain in the upper part of the now inverted bottle, and would not be
discharged, or its pungency wasted, while successive intermittent draughts were
drawn until but little liquor remained in the bottle, and thus by this means real
screw control" and genuine "intermittent discharge" are obtained, the opening is
rendered easy and quiet, this being effected quickly by screw action, waste and
splashing avoided, while the bottle can be screwed up again when empty, and so
kept clean and sweet.
"
Instead of the discharge being made from the side of the bottle neck, the
controller collar can be made larger and higher, and in cap form and screwed on
to a thread at the bottle top, and the exit be made from the bottle top into a
chamber in the cap, and thence from an opening in the side of the cap, the plug
turning in a thread in the centre of the cap, and the joint being made at the
shoulder, or against a rim near the bottle top.
The plug is made much smaller below its threaded part, and above the head,
than the bore of the bottle neck, so as to allow the liquor to pass out quickly.
Opposite the exit opening in the side of the neck of the bottle, a hole is made to
admit air to facilitate the discharge, and the same thing is done in the cap form of
controller. The opening in the cap for discharging the contents can be prolonged
in the form of a nozzle of any desired length or form, and that in the bottle neck
can be treated similarly.
The nozzle can also, in some cases, be made large enough to act as a measure,
and terminate in a tap.
Sometimes when cork is used instead of elastic to make the joint, a groove is
made in the plug just above the cork, and a rubber ring is fitted into the groove,
so as to press down the cork as the plug is screwed downwards.
My invention will be understood by the three examples shown on the annexed
drawings.
Figure 1 is a part sectional elevation of the apparatus for closing a bottle neck
in which a rubber ring is partly embedded, or held in place by an annular chamber
in the neck of the bottle, and against which, the plug of the stopper proper can be
brought into contact by internal gas pressure, or a screwing operation on the upper
part of the stem, the screw threaded part passing through the controller cap A,
which is itself screwed on to the bottle neck.
In this figure, the cap forms the medium by which the contents can be withdrawn
at B when the stopper is loosened, said cap having a vent hole C to facilitate
passage of the liquor.
According to Figure 2, which is a somewhat similar arrangement, I provide the
stem of the stopper with a cork D, or other closing medium, this being between a
bulb E at the bottom of the stem and a rubber washer F to retain the cork D
closer in its proper position and force it down in opening. The liquor outlet B,
by this arrangement, is through the side of the bottle neck, a vent Cbeing on the
opposite side. In this specimen, the closing medium may also be a rubber washer
in an annular channel at the lower part of the stem, as in Figure 3.
According to Figure 3, the cap A, which is somewhat after the shape shown
at Figure 1, has a spout B formed with it, and the closing medium is a rubber
washer in an annular channel at the lower part of the stem to impinge upon the
shoulders of the bottle in a similar manner to that referred to at Figure 2.
It will be observed by the arrangement shown on the drawings that the stopper

page_text: can be opened partially by turning it in the threaded portion of the controller so
as to enable the contents to be gradually withdrawn without that sudden rush
experienced when some other kinds of inside stoppers are used, consequently the
liquor not being dashed about, and the gas beaten out of it, retains its palatable
nature instead of being weakened and flattened to a serious extent.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In connection with bottles and other necked vessels, the double threaded fulcrum
screw controller A in collar form, in combination with the screw plug E, G, as
shown, narrowed at the exit part H (when needed), and when preferred, fitted
with, as in No. 2 drawing, the rubber holding washer, and when necessary, the
ventilator C, as shown, and the threaded neck exit bottle, or vessel; and when
preferred the controller in cap exit, or other exit form in combination with the
plain threaded bottle, or vessel, and above matters, as in drawing No. 1, for
instance.
