IMPROVEMENTS IN BOTTLES AND STOPPERS FOR THE SAME
Year: 1884

page_text: We, FREDERICK AUGUSTUS BIRD of 100, Moor Street, Birmingham, in the County
of Warwick, Ale and Porter Merchant, and. JOSEPH BEVERLEY FENBY, of Sutton
Coldfield, in the said county, Civil Engineer, do hereby declare the nature of our
invention for IMPROVEMENTS IN BOTTLES AND STOPPERS FOR THE SAME, to be as
follows:-
"
This Invention relates to improvements in bottles having stoppers which are
tightened and fixed by means of screw threads or inclines.
The object of the invention is to secure quickness in stoppering and unstoppering
such bottles. In carrying out the invention a stopper is provided with screw
threads or inclines which are not continuous for the whole circumference, but have
two or more parts cut away by grooving, as in an ordinary engineer's screw tap.'
The neck of the bottle is provided with corresponding screw threads or inclines,
also not continuous for the whole circumference, but cut away in two or more
parts of the circumference, so that the stopper may be inserted or withdrawn
without any rotary motion. A slight turn, through part of a revolution, will then
tighten the stopper; and a slight turn in an opposite direction will slacken it, and
enable it to be drawn straight out. The bottle is made airtight by a washer or
disc of rubber, cork, or other elastic material, in the usual way."
:
It is well to provide a stop or stops to prevent the stopper from being turned
too far back in unstoppering the bottle.

of Warwick, Ale and Porter Merchant, and JOSEPH BEVERLEY FENBY, of Sutton
Coldfield, in the said County, Civil Engineer, do hereby declare the nature of our
invention for IMPROVEMENTS IN BOTTLES AND STOPPERS FOR THE SAME, 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 improvements in bottles having stoppers which are
tightened and fixed by means of screw threads or inclines.
The object of the invention is to secure quickness in stoppering.and unstoppering
such bottles.
In carrying out the invention a stopper is provided with screw threads or inclines
which are not continuous for the whole circumference, but have two or more parts
cut away by grooving, as in an ordinary engineer's screw tap.
The neck of the bottle is provided with corresponding screw threads or inclines,
also not continuous for the whole circumference, but cut away in two or more parts
of the circumference, so that the stopper may be inserted or withdrawn without
any rotary motion. When the stopper is inserted into the neck of the bottle, a
slight turn, through part of a revolution; will tighten the said stopper, by-means-of
the screw threads, or inclines; and, when so tightened, a slight turn, in an opposite
direction, will slacken it, and enable it to be drawn straight out of the bottle.
The stopper is made to fit airtight in the neck of the bottle by means of a
washer, or disc of rubber, cork, or other elastic material, in the usual way.
It is well to provide a stop-or stops to prevent the stopper from being turned
too far in unstoppering the bottle.

screw threads or inclines within the neck. Counterparts of these screw threads
or inclines are in that half of the bottle neck which, in the drawing, is cut away.

for this bottle neck, and C is another view of the stopper, at right angles to the
view D. ee are the screw threads or inclines on the stopper, to engage with the
screw threads or inclines a a in the bottle neck for tightening the said stopper in
the said bottle neck. E is an inverted plan of the stopper, showing that the
inclines e e are not continuous for the whole circumference. f is a stop to prevent
the stopper from being turned too far in unstoppering the bottle. o is a ring of
rubber, cork, or other elastic material, to ensure an airtight joint between the
stopper and the bottle neck.
To stopper the bottle, the stopper D is dropped vertically into the neck, so that
the inclines e e pass down the spaces a¹ a¹, and the ring o touches the inside of the
bottle neck near the top. A slight turn of the stopper then engages the
inclines e e with the inclines a a, and ensures an airtight joint between the ring o
and the neck of the bottle near the top. A corresponding slight turn in the

then be lifted straight out of the neck.
Fig. 11 shews a bottle neck and stopper on the same principle as in Fig. 1, but
of a cheaper form of construction.
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
The formation of bottles, and stoppers for the same, having screw threads or
inclines, in the necks of the bottles and on the stoppers, not continuous for the
whole circumference, but partly cut away by grooving, to secure quickness in
stoppering and unstoppering, as described and illustrated.
