PROVISIONAL SPECIFICATION.
An Improved Stopper for Screw Mouthed Bottles.
I THOMAS ETHERIDGE HARPER of Pilgrim House, South Weald, in the
County of Essex, Gentleman, do hereby declare the nature of this invention to be
as follows:-
My improved stopper is formed with a screw thread extending for about half an
inch from the bottom and above this a stem or sbank smaller in diameter than
smallest part of the lower portion. Over this stem I stretch and firmly seat and
fix a ring or band preferably a ring of soft rubber. One method of so fixing the
ring is by means of a light fitting washer or sleeve of cork slightly larger in
diameter than the largest diameter of the rubber ring pressed down upon it and
there cemented. A stopper so constructed can be passed into a bottle while it is
being charged with aerated waters by being forced down the tube of the filling
machine and can be made to enter and take its place in the bottle if either the
bottle or the tube be turned in the right direction as it passes down the tube-the
cork sleeve or washer in such case makes a joint in the tube and holds the stopper
so as to give effect to the turning of the bottle and being larger than the rubber
prevents any abrasion or displacement of the latter in the process of so charging
and stoppering.
The stopper may if desired be made of lignum vitæ or of almost any impermeable
substance and in one two or more parts.
Cork may be substituted for rubber and vice versa and the ring band or washer
used to make the joint in the bottle may be fixed by other methods than that above
described.

COMPLETE SPECIFICATION.
An Improved Stopper for Screw Mouthed Bottles.
I, THOMAS ETHERIDGE HARPER of Pilgrim House South Weald in the
County of Essex, 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:-
My improved stopper is formed with a screw thread extending for about half
an inch from the bottom and above this a stem or shank smaller in diameter than
the smallest part of the lower portion. Over this stem I stretch and firmly seat and
fix a ring of soft rubber. One method of so fixing the ring is by means of a tight
fitting washer or sleeve of cork slightly larger in diameter than the largest diameter
of the rubber ring passed down upon it and there cemented. A stopper so con-
structed can be passed into a bottle while it is being charged with aerated water by
being forced down the tube of the filling machine and can be made to enter and
take its place in the bottle if either the bottle or the tube be turned in the right
direction as it passes down the tube-the cork sleeve or washer in such case makes
a joint in the tube and holds the stopper so as to give effect to the turning of the
bottle and being larger than the rubber ring prevents any abrasion or displacement
of the latter in the process of so charging and stoppering.
D

page_text: The stopper may be made of lignum vitæ or of almost any impermeable
substance and in one or more parts that is to say with a head for turning which
may be attached by any suitable appliances either after the stopper has been
placed in the bottle or if it is not desired to pass the stopper through the tube of
the filling machine then before the stopper is so inserted and in such latter case a
stopper in one piece such as is shewn in Figure 5 may be used.
Cork may where preferred be substituted for rubber except with regard to said
figure.
Figure 1 shews the thread and stem firstly described.
Figure 2 shews the rubber ring to be stretched thereon.
Figure 3 shews such stopper with ring and washer.
Figure 4 shews a stopper in one piece with rubber ring and permanent head.
Figure 5 shews the same without the ring.
The use of such a ring, instead of the band of rubber ordinarily used admits of
the stopper being turned after the joint has been made so that the head may come
flush with the bottle instead of projecting more or less above it. It also tends to
avoid breakage of the bottle and the consequent injury to the bottler.
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 :-
1. The construction of a screw stopper, for a bottle with an interual thread in its
mouth piece such as is above described and depicted.
2. The use of a rubber ring in combination with such screw stopper.
