Improvements in Bottle-stoppers and the like.
I REGINALD HADDAN of the firm of Herbert & Co., Patent Agents of
18 Buckingham Street, Strand W.C., in the County of Middlesex, Civil Engineer
do hereby declare the nature of this invention, a communication to me from abroad
by Richard Dalm of 403 Pitt Street, in the City of Sydney, New South Wales,
Australia, to be as follows:-
:-
This invention relates to bottles and the like and has for its object to construct
a stopper which shall permit of such bottles being opened and closed quickly and
easily without any mechanical appliance, and when filled with gaseous liquid to
be emptied partly without the atmospheric air having access to the bottle.
The stopper is of globular shape, having through its centre a hole of convenient
size and a small handle or projection by which the stopper can be turned and in this
way the bottle opened or closed.
In a recess in the neck of the bottle a ring of vulcanized india rubber is placed
against which the stopper is pressed.
The stopper is secured to the neck and screwed tightly down thereon when
closed by a metal cap which screws onto the outside of the bottle neck, screw
threaded to receive it. In the top of the cap, a large hole is cut to allow the liquid to
pass through when the bottle is being emptied.
Below the screw is a small groove for a wire to be fastened round after the cap
has been screwed on to the bottle. This wire secures the cap very effectually to
the bottle and prevents it being taken off without mechanical appliance, thus
securing the parts from being lost; only allowing the cap to be unscrewed sufficiently
for the stopper to be turned easily.
The stopper instead of having a handle by which it may be turned, can have for
this purpose, on one side of the hole a tube like projection, the cap being also
made in a corresponding manner, the stopper can be turned easily by the pro-
jecting part one quarter of a turn in the right direction sufficiently to open or close
the bottle properly.

COMPLETE SPECIFICATION.
Improvements in Bottle-stoppers and the like.
I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of
18 Buckingham Street, Strand, W.C. London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Richard Dalm of 403 Pitt Street in the City of Sydney, New
South Wales, Australia, and in what manner the same is to he performed to be
particularly described and ascertained in and by the following statement :-
This invention relates to bottles and the like, and its object is to construct a stopper
which shall permit of such bottles being opened and closed quickly and easily without
any mechanical device, without removing the stopper from the bottle; and which,
when arranged on bottles or syphons containing aerated liquids, shall enable a
portion of the contents to be withdrawn without the atmospheric air having access to
the interior of the bottle.
The accompanying drawing illustrates this invention as applied to a so called
፡፡ syphon "for containing aerated liquids.

page_text: In the case of syphons the head a of the bottle is made detachable from the neck
being held thereon by the same device which holds the stopper in the head. The
head a may with advantage, be made of glass or chinaware it is set in the neck
against a rubber washer c (Fig. 1) and carries the pipo d of the syphon. This pipe
extends upward into a passage à terminating above in a wide cylindrical chamber j
open above. With this chamber j communicates also the outlet pipe k of the syphon
entering therein at or just above the floor of said chamber. Around the upper edge
h
l
of the passage is formed the seat against which a rubber washer e on a holder fis
adapted to be pressed by the key or stopper g. The latter is a circular disc m pre-
ferably conical on its under side and formed with the shank n and thumb piece o
for turning it. On the upper face of the disc are projections p so that by turning
the key a quarter turn under the metal cap bit will be pressed down and the
rubber faced plug fe pressed firmly on the seat l. Now if the disc be turned so
that the elevated part of it stands up in the slot the washer will not press against
the seat and the liquid (driven by the pressure inside the vessel) will flow from
it, the vessel will be open. If the disc be turned again the bevelled sides of the
projections p enable it to be moved so that the elevated part is underneath the
portion of the cap b not cut out, it will be forced down just as much as the height
of the projection. The washer will be forced down the same distance and pressed
firmly against the seat cutting off all communication between the tube in the vessel
and outlet, in other words closing the vessel.
The metal cap b, which is passed over the head a and whose primary purpose is to
secure the stopper g in the head a, is formed as shown with a screw threaded part
to surround the neck of the bottle the latter being screw threaded to receive it.
The cap may be secured by wire. Instead of being screw threaded the neck of
the bottle may be formed with a series of annular grooves and the cap 6 also to
fit the same as shown in Fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In stoppers for bottles and the like the combination of the seat with
passages and k, plug fe, stopper g and cap b substantially as and for the purpose
set forth.
2. As a "syphon" stopper the combination of a removable head a with chamber j
seat and passages h and k, plugfe and stopper g, together with metal cap & securing
said parts substantially as set forth.
