IMPROVEMENTS IN BOTTLES AND IN STOPPERS FOR SAME
Year: 1884

page_text: I JOHN EDWARDS, of No 5, Chancery Lane, in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN BOTTLES
AND IN STOPPERS FOR SAME," to be as follows:-
This Invention relates to bottles in which the glass ball and India rubber washer
are employed as stoppers, and my improvements consist,
Firstly, In the employment of a cap or metal ring which can be expanded by
means of a mandril so as to fit into a groove in the bottle neck and keep the India
rubber ring in position, and
Secondly, In the employment of a conical washer resting on a ledge in the neck
of the bottle and forming a seating for the India rubber washer.
In order that my Invention may be more fully understood I hereto annex a sheet
of drawings illustrative thereof.
Figure 1. represents the neck of a bottle in section, A. being the India rubber
washer which rests upon the ledge a and is kept in position by the metal cap B.
which is made at first of the same diameter as the mouth of the bottle, and after
being inserted therein it is expanded by means of a suitable mandril and forced
under the shoulder b where it is retained by the elasticity of the washer a.
Figure 2. represents a sectional view of a bottle neck in which a conical metal
washer c is placed upon the ledge a which in this case is made with a plain
Burface.
-
The metal washer acts in the same manner as the angular ledge in forcing the
India rubber washer against the sides of the neck.

page_text: I, JOHN EDWARDS of No 5 Chancery Lane in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN BOTTLES
AND IN STOPPERS FOR SAME" 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 bottles in which the glass ball and india-rubber washer
are employed as stoppers, and my Improvements consist,
Firstly, in the employment of a metal ring or washer which can be expanded by
means of a mandril so as to fit into a groove in the neck of the bottle and so keep
the india-rubber ring in position and prevent it from being displaced by the glass
ball under the pressure of the aërating gases.
Secondly, in the employment of a conical washer resting on a ledge in the neck
of the bottle and forming a seating for the india-rubber washer equivalent to that
formed by constructing the seat in the neck of the bottle in the conical form.
'
And in order that my Invention may be more fully understood I hereto annex a
sheet of Drawings illustrative thereof.
Figure 1 represents the neck of a bottle in section, A being the india-rubber
washer which rests upon the ledge a which is here shewn formed with a sharp or
conical edge so as to form a firm seating for the rubber washer. The india-rubber
washer is kept in position by the metal ring or washer B which is made at first of
the sectional form shewn in Figure 2 small enough in diameter to fit into the
mouth of the bottle and after being inserted therein it is expanded by means of a
suitable mandril and the rim thereof forced under the shoulder b holding the
washer A firmly in its seat.
The ledge or seating a upon which the india-rubber washer A rests, forms part
of the bottle in the Figure above described but as it is not easy to construct the
same with accuracy in glass, I prefer to construct the groove in the neck rectangular
and form the conical seating in metal or any suitable material and this constitutes
the second part of my Invention shewn in Figure 3 which corresponds with
Figure 1 in every respect excepting that the ledge a of the first Figure is supplied
by the metal washer c which is both cheaper and more satisfactory for general use.
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-
Firstly. The application of an expansible metal washer of the form substantially
as herein shewn and described, for holding the india rubber washer firmly in
position within the groove of the bottle neck.
Secondly. The use of the conical ring c for the india-rubber washer to rest upon,
substantially as shewn and described in Figure 2 of the accompanying drawings.
