PROVISIONAL SPECIFICATION.
Improved Arrangement for Stopping Bottles.
1. CHARLES JACKSON of Lesowes, Moseley in the County of Worcester,
Engineer, do hereby declare the natur of this invention to be as follows:-
:―
The bottle is closed by a cap screwing on to the neck, the threads on the neck
and in the cap being in Segments, so that the cap can be slipped on the segments of
its screw passing between the segments of the screw on the neck. The cap is then
secured by a partial turn. At the top of the inside of the cap there is a valve of
asbestos or similar material in the form of a flat plate pivotted at the centre of
the cap this valve presses firmly against the top of the neck when the cap is
screwed home thereby making a tight joint. The pivotting of the valve allows it
to rest without turning upon the top of the neck, so that there is not the rubbing
action usual in this class of stopper.
Preferably one or both of the screw threads is slightly wavy so that, when the
cap is screwed home, there is no tendency for it to unscrew.

COMPLETE SPECIFICATION.
Improved Arrangement for Stopping Bottles.
I, CHARLES JACKSON, of Leasowes, Moseley, in the County of Worcester,
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 bottle is closed by a cap screwing on to the neck, the threads on the neck
and in the cap being in segments, so that the cap can be slipped on the segments
of its screw passing between the segments of the screw on the neck. The cap is
then secured by a partial turn. At the top of the inside of the cap there is a
valve of asbestos or similar material in the form of a flat plate pivotted at the
centre of the cap; this valve presses firmly against the top of the neck when the
cap is screwed home thereby making tight joint. The pivotting of the valve
allows it to rest without turning upon the top of the neck, so that there is not the
rubbing action usual in this class of stopper.
Preferably one or both of the screw threads is slightly wavy so that, when the
cap is screwed home, there is no tendency for it to unscrew.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are elevations at right angles to each other of a bottle made
according to this invention. Figure 3 is a vertical section of a stopper for the
same. Figure 4 is a vertical section of a modified stopper.
A are the screw segments on the neck of the bottle and B the corresponding
segments on the inside of the cap. C is a disc of asbestos or other material
connected to the centre of the cap by a pivot D.
It is preferred to arrange the screws as shown so that the two segments are at
the same distance from the top of the bottle and stopper otherwise the stopper
will only fit when put on one way. The number of threads in the screws may vary
from one upwards.

page_text: In place of having the sides of the cap continuous all the way round as shown
in Figure 3 they may consist merely of two lugs as shewn in Figure 4. In this
case it is desirable to have the threads of the screws undercut as shewn in
Figure 5 so that when the cap is screwed on there may be a tendency to draw the
lugs of the cap inwards.
•
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1. The combination of a bottle having screw segments upon its neck with a cap
having on its inside corresponding screw segments and a centrally pivotted disc.
2. Bottle stoppers substantially as described and shewn in the drawings.
