Improved Stopper for Bottles and other Vessels.
HENRY BEZER 19 Bankton Road, Brixton, in the county of Surrey, Engineer do
hereby declare the nature of this invention to be as follows
1-
The invention is described by the form of Stopper for a Bottle to contain Beer,
mineral waters, or other such liquids.
Proceeding from the mouth of the Bottle, and forming part of the thickness of the
neck is cast a ring. From the base of the ring, and beyond the required thickness of
the neck of the Bottle, and to a suitable depth down the neck of the Bottle is
cast projections forming at their base respectively inclined and parrallel planes and
stops. At two opposite points and through the thickness of the above named
projections are vertical slots forming keyways for the ends of a spring as herein-
after described. It will be understood that each slot leads to an inclined plane
terminating with a parrallel plane and a stop. The stopper consists of a capsule
within which is a layer of cork. Outside the capsule, banded across it and down each
side is a steel
spring.
The two ends of this spring are bent inwards under the capsule, and are of such a
length that the space between them is the diameter of the neck of the bottle. That
part of the spring band which is across the top of the capsule is sunk midway so that
it bears only upon the centre of the top of the capsule. The spring band is therefore
in pressure contact with the capsule at the centre of its top and under that part of it
which will encircle the neck of the bottle.
To keep the spring band in place, and ensure its turning with the Capsule, either
the sides of the Capsule can be notched to receive the bent in ends of the spring
band, or the spring band can be in a groove down cach side and across the top of the
capsule. To cork the bottle, when the capsule and two ends of its spring band are
passed far enough down the vertical slots before described to meet the inclined planes,
by turning the stopper to the right the inclined planes draw down the spring band
which by pressure upon the top of the capsule presses the cork bed on to the ring on the
top of the neck of the bottle, and as soon as the cork is fully compressed the spring band
yields to the continued turning of the stopper, and the bottle is corked with the spring
band ends booked under the parralled planes and against the stops. The parts are so
dimentioned that by frequent use of the same cork bed there would be a pull upon
the spring band in excess of the yield to pressure of the cork bed, and as the spring
band across the top of the capsule has its lowest point midway, although the inclined
planes on the neck of the bottle can draw the spring band downwards, the
contrary pressure of the bottle contents would have to exert much greater force
because pressure by the capsule upon that part of the spring band which bears
upon its centre is resisted by the bound conditions of the two ends of the spring
band under the parrallel planes on the neck of the bottle.
It is for this reason that I prefer to employ this form of spring although a useful
stopper might be made with a spiral or India Rubber spring between the cork bed
and the top of the capsule.

Improved Stopper for Bottles and other Vessels.
HENRY BEZER of 19 Bankton Road, Brixton in the County of Surrey Engineer
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 :-
The invention is described by a form of stopper for a Bottle to contain Beer,
mineral waters, and other liquids. The accompanying drawings show in Figure 2
plan of the Bottle neck. Figure 1 is a section through A B of one half of the
bottle neck. Figure 3 a view of the other half and the stopper is in this figure
shown in section, but it is not secured to the bottle. Figure 4 is a plan of the stopper.
Figure 5 shows the stopper secured to the bottle.
Figure 1 shows what would be about the inside formation of the bottle neck, and it
will be seen that on this half there is the projecting part a with inclined plane leading
to a parrallel plane of the opposite hand to the inclined plane leading to a parrallel
plane on the projecting part b, shown in Figure 3. At the mouth of the bottle is a
ring C, and between projections a and b are slots d E.
The spring fits over the capsule G as shown, and tight within the capsule G is
the cork bed H. The stopper is dropped on to the bottle as shown in Figure 3. The
turned in ends of the spring f passing down the slots d, E. The capsule G encircles
the neck of the bottle. The cork bed H reaching the ring C. Then by turning the
stopper to the right the respective inclined planes on projections a, b, draw down
the spring which bringing with it the capsule G compresses the cork bed H on to
the ring C.
The stopper is turned until the turned in ends of the spring fare in position as
shown in Figure 5. The stopper is removed by turning back again, and can bo
drawn from the bottle as soon as the turned in ends of the spring reach the
slots d E.
The parts are so made that with a partial travel along the inclined planes the cork
bed H is fully compressed on to the ring C, and then the spring yields to the
remaining travel along the inclined planes. With frequent use and compression of
the cork bed, there would always be in addition to its yield a pull upon the spring f,
and as that part of the spring f which is across the top of the capsule has its lowest
point midway, although the inclined planes on the neck of the bottle can draw the
spring down, the contrary pressure of the bottle contents would have to exert much
greater force, because pressure of the capsule upon that part of the spring f which
bears upon it is resisted by the bound conditions of the turned in ends of the spring f
under the parrallel planes on the neck of the bottle.
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 I
claim is―
The spring in combination with a capsule, cork bed, and bottle or other vessel's
neck operating substantially as hereinbefore described.
