William Beardsley Bottle Stopper
William Beardsley’s
patent application was filed February 27, 1885 and specified:
I,
William Beardsley, of Beacon…
Figure 1 is a cross-sectional view of my improved bottle-stopper and of
a bottle in part. Fig. 2 is
a plan view of the under side of the cap.
The bottle A, of any desired
shape or size, is provided with an externally-screw-threaded neck,
B, on which a screw-cap, C,
is screwed having a central aperture,
D.
On the under side of the cap
C a packing,
E, or leather, rubber, or other suitable material, having an
aperture corresponding to the aperture
D, is secured, and the bottle
contains a glass or other ball-valve,
F, adapted to close the
aperture D.
On the inside of the bottle, in practice, a series of triangular
or crescent-shaped projections, G,
are formed at a greater or less distance from the neck, said projections
extending continuously around the bottle.
The bottle is filled with soda-water or other aerated liquid
under pressure, which forces the ball-valve against the seat formed by
the packing E, thus closing
the bottle. To open the
bottle the ball-valve F is
pressed down and the liquid is permitted to flow out of the bottle.
When the bottle is opened, the ball
F rests against the ridges or
projections G, and is thus
prevented from closing the opening in the cap.
