IMPROVEMENTS IN BOTTLE STOPPERS
Year: 1885

page_text: We CHARLES MACKEY TAYLOR, of Lansdown Road, in the County of Essex,
Wine Merchant and ANTHONY PERCIVAL TURNER, of 28 Dalston Lane, in the
County of Middlesex, China and Glass Merchant do hereby declare the nature of
our said invention for "IMPROVEMENTS IN BOTTLE STOPPERS" to be as follows:-
This invention relates to the construction of an improved screw stopper for
closing bottles having screw necks.
Our improved stopper is constructed of a tube or hollow cylinder of suitable metal
such as steel or of other suitable material; the said tube or cylinder is formed by
moulding or otherwise with a male screw thread on its periphery so as to adapt it
to be screwed into the neck of a bottle formed with a corresponding female screw
thread. The upper end of the tube or cylinder is provided with a rim or flange
under which is placed a washer of suitable elastic material such as india rubber
for the purpose hereinafter described. Into this tubular casing thus formed I then
force or screw an ordinary cork, the said cork being longer than the tubular casing
so as to project from each end thereof and of a diameter such that it will tightly
fit within the casing the projecting ends expanding to a larger diameter.
To make use of a stopper of this construction it is screwed into the neck of a
bottle and the lower projecting end of the cork as soon as it passes the throttle
will expand and form a tight joint, further security being obtained by means of
the elastic washer between the flange of the stopper and the mouth of the bottle.
A stopper of this construction can be easily placed in and removed from a bottle
and should the cork portion of the stopper become dirty or worn it can be removed
and replaced by another cork.
In practice we have found that a convenient mode of manufacturing our
stoppers is to first place the screwed tube within a bottle neck and then to force
the cork therein by means of an ordinary corking machine.
Instead of forming the tubular casing with a screw thread as hereinbefore
described it will be obvious that the casing may consist of a plain tube provided
with two or more projections arranged so as to form parts of a screw thread.

page_text: When the tubular casing of our improved stopper is formed of a metal liable
to be acted upon by the contents of the bottle it is coated with tin or is otherwise
suitably protected.
We have described our improved stopper as being provided with an elastic
washer between the flange of the stopper and the mouth of the bottle but it will
be obvious that this washer may be dispensed with.
By our invention we provide a stopper in which the closing of the bottle is
effected by means of cork thereby preventing the contents of the bottle coming in
contact with any objectionable material.

COMPLETE SPECIFICATION.
Improvements in Bottle Stoppers.
We CHARLES MACKEY TAYLOR, of Lansdown Road in the County of Essex,
Wine Merchant and ANTHONY PERCIVAL TURNER, of 28, Dalston Lane, in the
county of Middlesex, China and Glass Merchant 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 to the construction of an improved screw stopper for
closing bottles having screw necks.
Our improved stopper is constructed of a tube or hollow cylinder of suitable
metal such as steel tinned metal or alloy or other suitable material: the said tube
or cylinder is formed by moulding or otherwise with a male screw thread on its
periphery so as to adapt it to be screwed into the neck of a bottle formed, with a
corresponding female screw thread. The upper end of the tube or cylinder is
provided with a rim or flange under which may be placed a washer of suitable
elastic material such as india rubber for the purpose hereinafter described. Into
this tubular casing thus formed, we then force or screw an ordinary cork or other
suitable elastic plug, the said cork being longer than the tubular casing so as to
project from each end thereof, and of a diameter such that it will tightly fit within
the casing, the projecting ends expanding to a larger diameter.
Instead of forming the tubular casing with a screw thread as herein before
described, it will be obvious that the casing may consist of a plain. tube provided
with two or more projections arranged so as to form parts of a screw thread.
In order to enable our invention to be fully understood, we will proceed to
describe the same, by reference to the accompanying drawing in which figure 1,
is an elevation, and figure 2, a vertical section of a bottle stopper constructed
L

page_text: according to our invention, the tubular casing being formed with a screw thread;
figure 3 is a section of a-bottle neck showing the screwed. tubular casing placed
therein previous to receiving the cork when manufacturing the stopper; figure 4,
is. a sectional elevation of part of a bottle showing the complete stopper in section
inserted in the mouth thereof; figure 5, is a similar view to figure 4, but showing
the stopper in sectional elevation; figure 5, is a detached view of the tube or
hollow cylinder and flange; figure 6, is an elevation showing the stopper with a
casing consisting of a plain tube provided with projections arranged to form parts
of a screw thread. Similar letters in all the figures represent similar or corre-
sponding parts.
Referring to figures 1 to 5, a represents the tube or hollow cylinder, of suitable
metal such as steel or of other suitable material, formed as shewn with a male
screw thread on its. periphery, so as to adapt it to be screwed into the neck A, of
a bottle formed with a corresponding female screw thread as shewn in figure 3;
b, is the rim or flange with which the upper end of the tube or cylinder a, is
provided and which can be milled, or serrated as shewn, to afford a better hold for
the fingers when screwing the stopper into a bottle neck; c, is the washer of
suitable elastic material such as india rubber, which washer when the stopper is
screwed home, forms a tight joint between the mouth A, of the bottle, and the rim
or flange b; d, is the cork, (or other suitable elastic plug) which is forced or screwed
into the screwed tubular casing a.
In practice, we have found that a convenient mode of manufacturing our stoppers,
is to first place the screwed tubular casing a in the neck A of a bottle (which may
be already filled with liquid) as shown in figure 3; the cork d, is then forced
therein by means of an ordinary corking machine; the cork d is longer than the
tubular casing and projects from each end thereof, as shewn, and is of such a
diameter that upon expanding it will tightly fit within the casing a, and the lower
projecting end as soon as it passes what is termed the throttle of the bottle will
expand to a larger diameter so as to form a tight joint in the bottle neck below
the screw thread thereof, as shewn in figures 4 and 5, further security being
obtained by means of the elastic washer c, between the flange b of the stopper and
the mouth A, of the bottle.
A stopper of this construction can be easily removed from the bottle, and can
be re-used by screwing it into the neck of the bottle, and should the elastic plug d,
of the stopper, become dirty or worn it can be removed and replaced by another
cork or plug.
We have described our improved stoppers as being manufactured by means of
an ordinary corking machine by the same operation as that by which the bottle is
corked or stoppered, but it will be obvious that we may employ any other suitable
method of manufacturing the stoppers.
The stopper illustrated in figure 6, is the same as that hereinbefore described
and shewn in figures 1 to 5 except that the tubular casing a, consists of a plain
tube instead of being screw threaded, and is provided with projections e, arranged
so as to form parts of a screw thread, or to project into the female screw.
When the tubular casing a, of our improved stopper is formed of a metal liable
to be acted upon by the contents of the bottle, it is coated with tin, or is otherwise
suitably protected.
We have described our improved Stopper as being in some cases provided with
an elastic washer c, between the flange 6 of the stopper and the mouth A of the
bottle but it will be obvious that this washer may be dispensed with.
By our invention we provide a stopper in which the closing of the bottle may
be conveniently effected by means of cork, thereby preventing the contents of the
bottle coming in contact with any objectionable material.
Instead of the milled edge of the flange b, of the stopper being turned downwards
as shewn in the drawing, we sometimes prefer to turn it upwards, as will be well
understood or the flange may be provided with any convenient projections so as
to give a firm hold,

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The manufacture and use of our improved Stopper for closing bottles, having
screw necks, consisting of a hollow cylinder, having projections on its periphery
adapted to fit into the screw of the bottle neck and having an annular flange b. on
the end of said cylinder, adapted to fit over the mouth of the bottle, and a plug of
cork or other suitable elastic material tightly enclosed within said cylinder, all
substantially as shewn and described.
"
2. Our improved stopper for closing bottles having screw necks consisting of a
hollow cylinder having projections on its periphery adapted to fit into the screw
of the bottle neck, a washer c, interposed between said cylinder and bottle neck,
and having an annular flange b, on the end of said cylinder adapted to fit over the
mouth of the bottle and a plug of cork or other suitable elastic material, tightly
enclosed within said cylinder all substantially as shewn and described.
3. Our improved stopper for closing bottles, having screw necks, consisting of a
hollow cylinder having male and female screw threads, an annular or other
equivalent flange b, on the end of said cylinder, and a plug of cork or other
suitable elastic material tightly enclosed within and filling up the female screw
threads of the cylinder, all substantially as shewn and described.
4. The manufacture and use of a cylinder and flange such as that shewn in
figure 5*, substantially as and for the purpose herein described.
