PROVISIONAL SPECIFICATION.
Improvements in the Stoppering of Internally Stoppered Bottles.
I DAN RYLANDS, of Hope Glass Works, Stairfoot, near Barnsley in the county of
York, Glass Bottle Manufacturer do hereby declare the nature of this invention to be
as follows:-
My present Invention relates to those Bottles which are stoppered with an internal
stopper which is retained in the neck of the Bottle by means of a contraction just at
the bottom of the neck; and according to my present invention I use a stopper
having a central circular portion around which an annular groove is formed, such
stopper at each end being formed of a pointed, tapered or conical shape, so that which-
ever way the stopper comes up to the mouth it will, by means of an India rubber
washer placed in the annular groove on the centre of the stopper, form an airtight
joint. This arrangement may be applied to bottles having a valve in the neck and
also having indents on each side of the neck.

1 DAN RYLANDS, of Hope Glass Works, Stairfoot, near Barnsley, in the County of
York, Glass Bottle 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 :-
My present Invention relates to those Bottles which are stoppered with an internal
stopper which is retained in the neck of the Bottle by means of a contraction just at
the bottom of the neck and according to my present Invention I use a stopper
having a central circular portion, around which an annular groove or grooves are
formed, such stopper at each end being formed of a pointed, tapered, or conical shape,
so that whichever way. the stopper comes up to the mouth it will, by means of an
India Rubber washer or washers placed in the groove or grooves on the centre
of the stopper, form an airtight joint. This arrangement may be applied to
bottles having a valve in the neck, and also to Bottles having indentations or internal
projections on the sides of the neck, as described and set forth in the specifications of
Patents previously granted to me and numbered 5445 of 1883, and 348 of 1885, and
1811 of 1886.
In order that my Invention may be fully understood, I append hereto four sheets of
drawings, marked with letters of reference, corresponding marks indicating the same
parts in the various figures. Figs. 1, 2, and 3 are sectional elevations, and Fig. 4 an
external elevation.
In Fig. 1, a is the stopper formed with two annular grooves bb, in which are
secured India Rubber rings e e, which make an airtight joint against the annular
seating d in the only two positions the stopper can assume, ff are indentations or
internal projections in the Bottle neck; e is an air valve fitted in one of the indents f;
and g represents the contractions at the base of the Bottle neck for preventing the
stopper a falling to the bottom of the Bottle.
In Fig. 2, the stopper a¹ has the central portion formed spherically, the spherical
portion being encased with the India Rubber or other pliable covering c as shown.
Fig. 3 shows the stopper a² fitted with only one India Rubber or other pliable ring c;
and H represents small circular indentations or internal projections formed in the
Bottle neck at right angles to the indentations ff.
Fig. 4 shows the outside head of valve e, and the two contractions gg on both
sides of the base of the Bottle neck for preventing the stopper falling to the bottom
of the Bottle.
It will be well understood that the mouths of the Bottles shown at Figs. 1, 2, and 3
may be varied in shape to suit either of the styles of stoppers a, a, and a². The
stopper a on sheet 1 is shown larger in external diameter in the middle portion of the
stopper than the internal diameter of the Bottle Mouth, and this principle I prefer to
follow in all cases wherever practicable. The stopper is dropped in before the Bottle
Mouth is formed with the Tools, and after the Bottle and stopper have been annealed

page_text: the rubber washer or washers is or are fitted on the stopper by means of Tools similar
to those generally used for fitting rubbers on stoppers.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1. In internally stoppered bottles the adaptation of stoppers a a¹ and a² in
combination with the valve e, the indentations ff, and the contractions g g substantially
as described.
2. In internally stoppered bottles the adaptation of stoppers a a' and a² in
combination with the indentations ff, and the contractions g g substantially as
described.
3. In internally stoppered bottles the adaptation of stoppers a a¹ and a² in com-
bination with the indentations ff the smaller additional indentations H H and the
contractions g g substantially as described.
