IMPROVEMENTS IN INTERNALLY STOPPERED BOTTLES
Year: 1884

page_text: I DAN RYLANDS of Hope Glass Works Stairfoot Barnsley in the County of York
Glass Bottle Manufacturer do hereby declare the nature of my said Invention for
IMPROVEMENTS IN INTERNALLY STOPPERED BOTTLES to be as follows:-
I form during the process of manufacture a bottle having an internal female
screw in the mouth and at the bottom of such screw a ledge on which may rest an
india rubber ring or a ring of similar suitable material.
To work in this screw I make a mouthpiece in the form of a hollow cylindrical
stopper having a suitablo male screw formed on outside thereof.
This hollow cylindrical stopper or mouthpiece has a head or top part for the hand
to grasp and the screw formed on outside of this mouthpiece only reaches to under-
side of head-By means of this head the hollow cylindrical stopper or mouthpiece
can be easily operated upon to either screw tight or unscrew by hand and does not
require any special instruments for this purpose.
After the bottle has been made as before described and annealed, I place inside
it a Glass Ball or other suitable Internal Stopper and I then place on the ledge at
bottom of screw in bottle mouth a ring of indiarubber or other suitable elastic
substance. I then screw in by hand the hollow cylindrical stopper or mouthpiece
(which may be made of glass, earthenware or any other suitable material) until
the bottom of such mouthpiece touches and presses on the India Rubber Ring thus
preparing it for forming an airtight joint when the glass ball or other suitable
Internal Stopper is forced against it. To open a bottle thus stoppered internally
it is only necessary to give the hollow screw Stopper or mouthpiece a halfturn
with the hand, and by means of the top part or bead this is easily done-The
india rubber ring may be attached to bottom of mouthpiece and if a groove be
formed at bottom of screw in bottle mouth, instead of a ledge, it will only allow
the hollow stopper or mouthpiece to be unscrewed a certain distance and thus
prevent same being lost from the bottle.
I would here remark that I am aware that Internally Stoppered Bottles have
already been made with hollow screw mouthpieces but these have hitherto been of
such a form that they required a special tool to insert or withdraw them and
bottles thus fitted had to be opened by pressing the ball or other stopper down as
these screw mouthpieces had no head or top part for the hand to grasp.

internal stopper at all.
I am also aware that a patent has been applied for, for a screw mouthpiece to
work externally on the Bottle Mouth but this is very different to my present
invention which works internally.
COMPLETE SPECIFICATION.
- I DAN RYLANDS of Hope Glass Works in the County of York, Glass Bottle
Manufacturer do hereby declare the nature of my invention för LMPROVEMENTS
IN INTERNALLY STOPPERED BOTTLES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
I form during the process of manufacture, a bottle having an internal female
screw in the mouth, and at the bottom of such screw a ledge, on which may rest
an india-rubber ring or a ring of similar suitable material.
To work in this screw I make a moutlipiece in the form of a hollow cylindrical
stopper, having a suitable male screw formed on outside thereof.
This hollow cylindrical stopper or mouthpiece has a head or top part for the hand
to grasp, and the screw formed on outside of this mouthpiece only ronches to
underside of head. By means of this head the hollow cylindrical stopper or
mouthpiece can be easily operated upon to either screw tight or unscrew by hand
and does not require any special instruments for this purpose.
After the bottle has been made as before described and annealed, I place inside
it a glass ball or other suitable Internal Stopper, and I then place on ledge at
bottom of screw in bottle mouth a ring of india-rubber or other suitable elastic
substance. I then screw in by hand the hollow cylindrical stopper or mouthpiece
(which may be made of glass earthenware or any other suitable material) until the
bottom of such mouthpiece touches and presses on the india rubber ring, thus
preparing it for forming an airtight joint when the glass ball or other suitable
Internal Stopper is forced against it. To open a bottle thus stoppered internally
it is only necessary to give the hollow scrow Stopper or mouthpiece a half turn
with the hand, and by means of the top part or head this is easily done.
The india rubber ring may be attached to bottom of mouthpieco, and if a groove
be formed at bottom of screw in bottle mouth, instead of a ledge, it will only allow
the hollow stopper or mouthpiece to be unscrewed a certain distance and thus
prevent same being lost from the bottle.
.:
I would hore remark that I am aware that Internally Stoppered Bottles have
already been made with hollow screw.mouthpieces, but these have hitherto been of

page_text: such a form, that they require a special tool to insert, or withdraw them, and
bottles thus fitted had to be opened by pressing the ball or other stopper down,
as these screw mouthpieces had no head or top part for the hand to grasp.
My present invention obviates the necessity for pressing on the Ball or other
internal stopper at all.
I am also aware that a patent has been applied for, for a screw mouthpiece to
work externally on the Bottle mouth; but this is very different to my present
invention which works; internally.
In order to enable my invention to be fully understood, and practically carried
out, I will proceed to describe the same with reference to the accompanying
drawings.
Fig. 1. is a sectional elevation of my improved Bottle.
Figs 2 and 3, are respectively elevation and plan of an india-rubber ring or ring
of any similar material.
Figs 4, and are respectively elevation and plan of my improved 'hollow
cylindrical stopper or mouthpiece.
Figs. 6, and 7, are respectively elevation and plan of a modified form of
mouthpiece.
Fig. 8, is a sectional elevation of Bottle neck showing a modified form of
mouthpiece screwed therein.
Fig. 1 is an elevation of the bottle-maker's tongs or tool, which I use for forming
the screw threads in bottle mouth.
Fig 2 is also an elevation of the bottle-maker's tongs, but showing the same in
position during the operation of forming bottle mouth.
Fig. 3 is a cross section on line 1. 1. of Fig 2*
In forming the internal female screw C, (fig. 1,) which has a ledge D, at the
hottom, on which ledge the india-rubber ring, E, (figs 2 and 3) may rest), I use the
tongs or tool figs 1° 2° and 3* of which the following is a description. The plug 2
has a screw thread 3, formed on it, to correspond with the female screw, C, (fig 1,)
to be formed in bottle mouth, and at the bottom of plug 2, is a ledge or ring 4,
which corresponda with the ledge, D, fig 1. The plug 2 has a bearing 5, in the
swiller 6, and has attached to it the square rod, 7, which has a circular bearing 8,
in the cross piece 9. Fastened to the leg 10 is the guide 11, which is made in the
form shown at fig 3* having a square space 12, in which rests the square rod 7,
when the legs 10, 10, are apart (fig 1), and an oval space 13, so that the square
rod 7, inay freely revolve, when the legs. 10, 10, are closed, as shown at figs 24
and 3. The dies 14, 14, are formed to suit the external form of mouth of bottle.
After placing a ring of molten glass around the top portion of neck of bottle
which has just been blown; I place the interior of mouth of bottle onto plug 2,
then I press to the legs 10, 10, thus causing the dies 14, 14, to come in contact
with the outside of mouth of bottle, as shown at fig 2. I then revolve the bottle
by means of a pontil in the usual way, during which operation the dies 14, 14, form
the exterior, and the plug, 2, (which revolves simultaneously with the bottle) forms
the interior of bottle mouth. Having satisfactorily performed said operation,
I then release the legs 10, 10, (which are made with a certain amount of elasticity)
when the dies 14, 14, spring apart, and the square space 12, in the guide 11, fits
onto the square rod 7, and so stopping the square rod, 7, from revolving with the
bottle, the plug 2, (being attached to the square rod 7 by means of the screw O,) is
also prevented from revolving. It will now be clearly seen that by still revolving.
the bottle in the direction which shall cause the mouth thereof to unscrew from
plug 2, that the bottle will be forced from said plug 2, and this completes the
formation of bottle mouth with the female screw C, formed therein (figs 1 & 8).
To work in this screw mouth C, fig 1, I make a mouthpiece A (figs 4, 5 6 and 7)
which is in the form of a hollow cylindrical stopper, having a suitable male screw F,
formed on outside thereof, I preferably make the threads of this male screw F, a
little less in thickness than the threads of the female screw C, in bottle mouth, by
which means spaces i, i, (fig 1) are left between such threads; or the threads of

page_text: the male screw F, may have an air space or groove k, cut through them as shown
at figs 6, 7 and 8.
The hollow cylindrical stopper or mouthpiece, A, has a head or top part G, which
is for the hand to grasp, and the screw F, only reaches to the underside of head G.
By means of the head G, the hollow cylindrical stopper or mouthpieco A, can be
easily operated upon, to either scrow tight or unscrew by hand and does not require
any special instruments for this purpose.
After the bottle B, has been made in the manner herein before described, and
subsequently annealed, I place inside it a glass ball K, (6g 1) or other suitable
internal stopper. I. then place on ledge D (which is formed at bottom of screw C,
in bottle mouth) a ring, E, (figs 2 and 3), which is made of india-rubber or other
suitable elastic substance. I then screw in by hand the hollow cylindrical stopper
or mouthpiece A, (which may be made of glass earthenware or any other suitable
material) until the bottom portion a, of tho mouthpiece A, touches and presses on
the india-rubber ring, D, thus preparing it for forming an airtight joint, when the
glass ball K, or other suitable internal stopper is forced against it as shown
at fig 1.
To open a bottle thus stoppered internally it is only necessary to give the hollow
screw stopper or mouthpiece A, a half turn with the hand, and by means of the
top part or head, G, this is easily done, the gas will then escape through the
spaces i, i, between the threads of the female screw C, and the male screw F, (fig 1);
or out of the air space or groove & (figs 6, 7, and 8) thus causing the internal
stopper K, or any other suitable internal stopper to fall, when the contents of the
bottle may be poured out.
With reference to fig. 8, the india-rubber ring, E, is attached to bottom of
mouthpiece A, and has a groove b, formed at bottom of screw C, in bottle mouth,
wherein the india-rubber ring, E, rests; by this arrangement the hollow stopper or
mouthpiece A, can only be unscrewed a certain distance thus preventing the same
being lost from the bottle.
I am aware that internally stoppered bottles have already been made with
hollow screw mouthpieces, but these have hitherto been of such a form that they
require a special tool to insert or withdraw them, and bottles thus fitted had to be
opened by pressing in the ball K, or other internal stopper, as these screw
mouthpieces had no head or top part G, for the hand to grasp, nither had they
spaces i, or air grooves k, to allow the gas to escape. My present invention
obviates the necessity for pressing on the ball K, or other internal stopper at all.
. I am also aware that a patent has been applied for, for a screw mouthpiece to
work externally on the Bottle mouth but this is very different to my present
invention, which works internally.
Having now particularly described and ascertained the nature of my said
Invention and in what inanner the same is to be perforined I declare that what
I claim is
Firstly) The Bottle B, in combination with the hollow mouthpieco A, having a
head G, and screw threads F; substantially as herein described and represented in
figs 1, 2, 3, 4, and 5.
Secondly) Tho hollow screw mouthpiece A having a head, G, and air space k; in
combination with bottle, B, and flexible ring E; substantially as herein described
and shown in firs 6. 7. and 8.
