PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Bottles.
I, JAMES BURBRIDGE of the firm of Messrs. Warne & Co. of the India Rubber-
Works, Tottenham, in the County of Middlesex, India, Rubber Manufacturers,, do
hereby declare the nature of this invention to be as follows:-
This invention relates.more particularly to screw-down plug stoppers for bottles of
various kinds, such as aerated water or hot water bottles.
In plug stoppers, it is usual to screw down onto a washer of india rubber or leather
to make a tight joint. This washer, after a time, becomes loose, drops off, and is lost,
thus rendering the stopper practically valueless.
In metal stoppers such as used for hot water bottles, the metal, becomes very hot,
and it is unpleasant and inconvenient, for that reason, to remove the stopper.
Now the object of my invention is to obviate these inconveniences, and to this
end I cover the stopper with an india rubber cap, which I form in one with, the
washer.
The rubber is, moulded and vulcanized onto the plug in the manner now well
understood.
The cap will extend some distance down below the top of the stopper, and will form
a deflector to prevent the contents of the bottle flying up in the face of the person
opening the bottle.
It will also serve to prevent the outgoing air causing the hot water to splash up
when the hot water bottle is being filled.
Dated this 30th day of October 1889.
COMPLETE SPECIFICATION.
Improvements in Stoppers for Bottles.
I JAMES BURBRIDGE of the firm of Messrs. W. Warne and Company, of the India
Rubber Works, Tottenham in the County of Middlesex, India Rubber Manufacturers,
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 more particularly to screw-down plug-stoppers for bottles of
various kinds, such as aerated water, or hot water bottles.
In plug stoppers it is usual to screw down onto a washer of india rubber or leather,
to make a tight joint. This washer after a time becomes loose, drops off, and is lost, thus
rendering the stopper practically valueless.
In metal stoppers such as used for hot water bottles, the metal becomes very hot,
and it is unpleasant and inconvenient, for that reason, to remove the stopper.
Now the object of my invention is to obviate these inconveniences, and to this
end I cover the stopper with an india rubber cap, which I form in one with the
washer. The rubber is moulded and vulcanized onto the plug in the manner now
well understood.
The cap will extend some distance down below the top of the stopper, and will form
a deflector, to prevent the contents of the bottle flying up in the face of the person
opening the bottle. It will also serve to prevent the outgoing air causing the hot
water to splash up, when the hot water bottle is being filled.
In the accompanying drawing, Fig. 1 is a sectional elevation of a screw stopper

page_text: produced according to my invention. Figs. 2 and 3 show the adaptation of my
invention to a hot water bottle, and Fig. 4 is a cross section of the metal nozzle.
In these Figures, A will be the metal nozzle for hot water bottle, or it may be the
neck of a bottle, and B is the stopper proper. C is the india rubber cap which covers
the stopper, and is formed in one with the washer C. The sides are prolonged
downwards so as to form a petticoat or guard C2 round the neck of the bottle, which,
in the case of aerated liquids, would prevent the contents of the bottle.flying up in the
face of the person opening the bottle.
In adapting the stopper to hot water bottles, I may find it convenient to attach a
stem D to the stopper B, which may take into a socket E formed in the metal
nozzle A, so that the stopper cannot, be withdrawn from the bottle and be lost..
.
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 :-
:-
.In stoppers for bottles, the combination with a screw plug, of a cáp C, washer C³,
and downwardly extending petticoat or guard, all formed of vulcanized india rubber
in one piece, as herein shown and described.
