page_text: 1 PERING CASTLE SMITH, of 4 King William Street, in the County. of London,
Gentleman, 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 stoppering of bottles whereby the contents can be drawn
off froin the bottle without removing the stopper..
The stopper is constructed in the form of a sphere with a cylindrical.channel
therethrough.
The stopper is provided with trunnions taking into a groove formed in the neck
of the bottle, forming bearings for the trunnions on which the stopper may be
turned until the said channel running therethrough is in open communication with
the neck of the bottle, when the contents may be poured off, and the stopper again
locked by turning the same on its trunnions.
And in order that my invention may be better understood and carried into practice,
I will now proceed to describe the same with reference to the accompanying
drawings in which, similar letters indicate corresponding parts throughout.
Figure 1 is an elevation of the stopper.
Figure 2 is a plan of the same.
Figure 3 is a transverse section of the neck of the bottle.
Figures 4 and 5 are longitudinal sections of the same taken at right angles to each
other.
Figure 4 shews the stopper in open communication with the interior of the bottle
neck, and
Figure 5 shews the stopper in closed position.
Figure 6 is a longitudinal section of the bottle neck without the stopper.
Figures 7 and 8 are elevation and bottom plan of a suitable key for inserting the
stopper in the neck of the bottle.
According to this invention, I construct a spherical stopper A with trunnions B and
a central aperture C. Around one side of the said aperture, I place a suitable lip D,
to guide the liquid when being poured from the bottle formed upon or affixed to the

page_text: spherical stopper as found convenient.. I also place a projection E upon the outer
circumference of the said spherical stopper for the purpose of turning the same round
by means of the finger or thumb upon its trunnions.
The top of the neck of the bottle I make of a shape and size to correspond with the
spherical stopper and provide it with a cork or other elastic annular seating F fitting
into a corresponding groove in the bottom of the neck, and also with a curved slot or
groove G turned up at the bottom H. Into the curved slot or groove G, the
trunnions B of the spherical stopper are passed and the stopper pressed down upon
the seating F until the trunnions are passed into the end H of the. curved slot or
groove G.
To secure the necessary pressure to place the stopper in position within the bottle
neck, I use a key with a conical shaped end J provided with two or more pro-
jections K fitting into corresponding slots or grooves L formed upon the top of the
aperture C.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that, what
I claim is -
1. The bottle stopper with a central aperture, and turning upon trunnions
constructed and operating substantially as and for the purpose herein before set
forth and illustrated in Figures 1, 2, 4 and 5.
2. In combination with a bottle stopper as described in the preceding claim, the
bottle neck with a curved slot or groove and india-rubber or other elastic annular
seating, substantially as and for the purpose hereinbefore set forth and illustrated in
Figures 3 to 6.
3. In combination with a bottle and stopper .constructed as described in the
preceding claims, a key with a conical end and projections taking into corresponding
slots formed upon the top of the aperture in the stopper substantially as and, for the
purpose: hereinbefore set forth and illustrated in Figures 2: 7 and 8.
Dated this 10th day of December 1888.
