for an Invention of "IMPROVEMENTS IN OR CONNECTED WITH THE STOPPERING
OF BOTTLES FOR CONTAINING ANDATED LIQUIDS"
PROVISIONAL SPECIFICATION left by the said, William Wilson Macvay
and Richard Sykes at the Office of the Commissioners of Patents on the
24th May 1883.
WILLIAM WILSON MACVAY and RICHARD SYKES, trading as Sykes Macvay,
& C° of Castleford in the County of York, Glass. Manufacturers "IMPROVEMENTS
IN OR CONNECTED WITH THE SPOPPERING OF BOTTLES FOR CONTAINING AERATED
LIQUIDS."
One of the objects of our invention is to provide stoppers for bottles which
contain aerated liquids so that the liquid may not be impaired by the material of
which the stopper is made, as is sometimes now the case when India rubber is used
as a cushion for the ball or other stopper to come against.
According to our invention we form the inner part of the neck sometimes with
a flange and sometimes without, when formed with a flange according to one
arrangement for a suitable distance below same we curve or bulge the interior
surface of the neck making the lower end of the curve of or about the same
diameter as the upper end, the curve may be concave or convex. Into this
curved receptacle we force an elastic ring' preferably previously shaped to the
shape of the curved receptacle. When made taper we form a ledge in the bottle
neck to receive and support a correspondingly shaped elastic ring. The base of
the taper ring is larger than the orifice so that the internal pressure presses the
ring against the tapered sides of the neck.
Sometimes we serrate the neck below the flange in which case it is not
necessary to bulge curve or taper the neck, as in this latter case the cork or other
ring would be straight and become embedded in the thread of the screw.
- >
The elastic ring is annular and may be made of cork which we prefer or of any

page_text: other suitable flexible material not injurious to the contents of the bottle. When
made of cork the latter may be made non-porous by steeping it in a chemical
composition for that purpose.
The stopper may be made of a Vor of double elongated V conical or spherical
form and with a collar if desired between the cones or base of one, or of other
suitable convenient shape and of glass preferably. 'The cork or other ring is
forced into the neck by machine; we do not limit ourselves to the depth of the
ring which may be a quarter of an inch less or more.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Wilson Macvay and Richard Sykes in the Great Seal
Patent Office on the 24th November 1883.

One of the objects of our invention is to provide stoppers for bottles which
contain aërated liquids so that the liquid may not be impaired by the material of
which the stopper is made, as is sometimes now the case when India rubber is
used as a cushion for the ball or other stopper to come against..
According to our invention we form the inner part of the neck sometimes with
a flange and sometimes without, when formed with a flange according to one
arrangement for a suitable distance below same we curve or bulge the interior
surface of the neck making the lower end of the curve of or about the same
diameter as the upper end the curve may be concave or convex. Into this curved
receptacle we force an elastic ring preferably of cork and previously shaped to the
shape of the curved receptacle
Figure 1 of the accompanying drawings shows the neck of a bottle for con-
taining aërated liquids made in this manner, and in order to illustrate the invention
as clearly as possible we have shown this neck and the others which follow drawn
on a larger scale than the size they are usually made; these remarks also apply
to the stoppers and elastic rings.
a is the flange on the inner part of the neck b of the bottle, the neck is bulged
or curved downwards below the flange as shown in the drawing c shows the
cork or other elastic ring forced into this curved space below the flange a where it
adapts itself to the shape of the curve, and it is owing in a great measure to the
bulge shape of the curve that the elastic washer c is kept in position below the
flange a.
Figure 2 shows in sectional elevation. Figure 3 in plan this washer before it is
forced into the neck of the bottle by a machine and Figure 4 shows in side

page_text: elevation and Figure 5 in plan, one of the stoppers which we prefer to use -in
connection with our invention; d is the collar on the stopper which collar abuts
as shown when the bottle is full, against the under side of the elastic ring c while
the sides of the cone shaped end wedges itself against the ring or washer c.
When the inner part of the neck is made taper we form a ledge in the bottle
neck to receive and support an elastic ring. The base of the taper ring is larger
than the orifice so that the internal pressure presses the ring against the tapered
sides of the neck.
Figure 6 shows in longitudinal vertical section a bottle made and fitted in this
manner, a is the flange or ledge at the base instead of the upper end of the neck as
before with internal taper neck above same as shown. cis the correspondingly
shaped ring which has adapted itself to the shape of the neck as shown. Figures 9
and 10 show in sectional elevation and plan respectively the ring before it is
inserted in the neck of the bottle, and Figures 7 and 8 show in side elevation and
plan respectively the stopper which we may in this case employ; d is the collar as
before which abuts as in the previous case against the under edge of the flexible
ring which latter is pressed up the sloping edge of the bottle neck so that the
greater the internal pressure within the bottle the tighter the ring c becomes
jambed. As shown the stopper has only one cone and sometimes we serrate the
neck below the flange in which case it is not necessary to bulge curve or taper the
neck as in this latter case the cork or other ring would be straight and become
embedded in the threads of the screw or ridges
Figure 11 shows a bottle neck made in this way and with a glass ball stopper.
Figures 12 and 13 are views in sectional elevation and plan of the ring before
insertion in the bottle neck. As seen the flexible ring after being prepared as
hereafter described is forced into the neck and the cork or other material of which
it is composed becomes embedded in the serrations or threads formed as shown in
the neck of same and the ball or other stopper is pressed against the cork seat as
before.
The elastic ring is annular and may be made of cork which we prefer or of any
other suitable flexible material not injurious to the contents of the bottle. When
made of cork the latter may be made non-porous by steeping it in a chemical
composition for that purpose.
The stopper may be made of a V or of double elongated V conical or spherical
form and with a collar if desired between the cones or base of one or of other
suitable convenient shape, and of glass preferably. The cork or other ring is
forced into the neck by machine.
We do not limit ourselves to the depth of the ring which may be a quarter of
an inche less or more.
Having now described the nature of the said invention and in what manner the
same is to be performed we declare that we are aware that it is not new to bulge or
curve the inner surfaces of the necks of bottles for containing aërated liquids
neither is it new to taper or to serrate or groove the inner surfaces of the neck,
neither is it new to employ cork as a washer we wish it therefore to be distinctly
understood that we lay no claim broadly to such devices or arrangements when
taken alone or separately but We claim.
First In the stoppering of bottles for containing aërated liquids the combined
arrangement of the bulging or curving the inner surface of the neck with an
elastic cork or other ring substantially as described with reference to Figures 1, 2
and 3 of the accompanying drawings.
'
Second: In the stoppering of bottles for containing aërated liquids the tapering
of the inner part of the neck in combination with a cork ring made and prepare f
as described all substantially as and for the purposes set forth with reference to
Figures 6, 9 and 10 of the accompanying drawings.
Third: In the stoppering of bottles for containing aërated liquids the serrating
the neck below the flange to receive the cork ring made and prepared as described

page_text: all substantially as set forth with reference to Figures 11, 12 and 13 of the
accompanying drawings.
Fourth-The several stoppers shown at Figures 4 and 5 and 7 and 8 when
used in combination with the neck fitting appliances all substantially as set forth.
In witness whereof we the said William Wilson Macvay and Richard Sykes
have hereunto set our hands and seals this Twentyfirst day of November in
the year of our Lord One thousand eight hundred and eighty three.
