PROVISIONAL SPECIFICATION.
Improved Means for Stoppering Bottles and similar Vessels.
I, WILLIAM GORDON POTTER, of 99, Warwick Street, Greenhoys, Manchester,
in the County of Lancaster, Consulting Engineer, do hereby declare the nature of
this invention to be as follows:-
My invention relates to improved means for stoppering bottles, and similar
vessels.
For this purpose I make the bottle and stopper as follows, that is to say: I form
on the interior of the neck of the bottle an interrupted screw thread, in two, three
or more sections or segments, and below this screw-thread I form a projection or
seating to receive a ring or washer of cork, india-rubber, or other suitable material.
Moreover, I make the stopper with a corresponding interrupted or segmental screw-
thread, and below this screw-thread I form a recess or reduce the size of the
stopper, so that its lower end will serve as a plug to receive or enter the said ring or
washer. Therefore when the stopper is locked in the bottle the latter will be
perfectly air or gas-tight.
The screw-threads on the bottle-neck and stopper are made in two or more
segments so that when the stopper is put into the bottle-neck, it is only necessary
to turn the said stopper one-fourth, one-sixth, or other fraction of a revolution to
lock or secure it firmly in the bottle.

The bottle may be made of glass, stone or other suitable material, and the stopper
or plug may be made of cork, india-rubber, glass porcelain or other suitable
material.

COMPLETE SPECIFICATION.
Improved Means for Stoppering Bottles and similar Vessels.
I, WILLIAM GORDON POTTER, of 99, Warwick Street, Greenheys, Manchester,
in the County of Lancaster, Consulting 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 :-
My invention relates to improved means for stoppering bottles and similar
vessels.
..
For this purpose I make the bottle and stopper as follows, that is to say :-I
form on the interior of the neck of the bottle an interrupted screw-thread in two,
three or more sections or segments, and below this screw-thread I form a projection
or seating to receive a ring or washer of cork, india-rubber or other suitable
material. Moreover I make the stopper with a corresponding interrupted or
segmental screw-thread, and below this screw-thread I form a recess or reduce the
size of the stopper so that its lower end will serve as a plug to receive or enter the
said ring or washer. Therefore, when the stopper is locked in the bottle, the latter
will be perfectly air or gas tight. The screw-threads on the bottle-neck and stopper
are made in two or more segments, so that, when the stopper is put into the bottle-
neck, it is only necessary to turn the said stopper one-fourth, one-sixth or other
fraction of a revolution to lock or secure it firmly in the bottle.

page_text: In the accompanying drawing
Figure 1 is a sectional elevation showing one form of bottle and stopper made in
accordance with my said invention.
Figure 2 is a horizontal section on the liner, a, Figure 1, and
Figure 3 is a sectional elevation showing another form or modification of my
invention.
A is the bottle; B is the stopper. a, a are the segments of the interrupted
screw-thread in the bottle-neck; b, bare the segments of the interrupted screw-
thread on the stopper. c is the seating in the bottle-neck for the cork or other ring
or washer d. The stopper B is reduced in size at its lower end so as to form a
plug e to fit into the ring or washer d.
In the form of my invention shown in Figures 1 and 2, the ring or washer d is
fitted into an annular groove or recess just above the seating c, and the plug e is
made of cylindrical form, or it may be slightly taper or conical, so that, when the
stopper is inserted in the bottle-neck, the pluge will fit more or less tightly into the
cork or other washer d. The turning of the stopper about its axis through one-
sixth of a revolution will then cause the squeezing of the said washer between the
-stopper and the seating c, and the locking or securing of the stopper in the bottle,
thus effecting the closure of the bottle in such a manner that it. is perfectly
gas-tight.
In the modification of my eaid invention shown in Figure 3, the washer d is placed
upon the plug e, which is made square, or it may be of other suitable shape, such as.
triangular, semi-circular or polygonal, so as to ensure the turning of the said
washer with the stopper. When the stopper is inserted in the bottle-neck, the
washer d comes in contact with the seating c; then, by turning the stopper one
sixth of a revolution, the said washer is squeezed between the said stopper and the
seating c so as to tightly close the bottle, and the stopper is at the same time locked
or firmly secured in the bottle..
The bottle may be made of glass, stone or any other suitable material; and the
stopper or plug may be made of glass, porcelain or other suitable material.
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 improved means herein before described and shown in the accompanying
drawing for stoppering bottles and similar vessels.
