PROVISIONAL SPECIFICATION.
Improvements in Bottle Stoppers.
I, GILBERT RAE of Balbridge Works, Dunfermline, Aerated Water Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to bottle stoppers or caps and it has for its object to
improve the construction of such stoppers or caps.
In making my improved stopper the cap piece which fits on to the top of the
bottle is screwed, on the inside, at its lower end. Into the screwed part inserted
an exteriorly screw-threaded ring. The ring is made or split vertically in two
pieces, one piece being, preferably, provided with projections on it which fit into
recesses or holes in the other piece. The ring fits on to the bottle neck and the
cap is screwed on to it so bringing the pieces close together and firmly gripping the
bottle. The cap is preferably open at the top and is exteriorly screw threaded to
receive a small internally screwed cover which when screwed down covers the
opening in the cap and prevents liquid escaping from the bottle. The screwed
cover has in it a small valve, the spindle of which passes out through the top of the
cover. The valve is capable of opening downwards. The valve, when the cover is
on the bottle, is held tight against its seat, which is formed in the top of the cover,
by the pressure of gas in the bottle. The valve has a rubber washer on it or is
faced with rubber so as to close tight against its seat. The outer end of the valve
spindle which has, preferably, arms or equivalent fitted to it for preventing the
valve falling through into the bottle and also to guide it in its upward and down-
ward movements, works in a hollow exteriorly screwed projection on the top of the
cover. When the bottle is to be filled with aerated water and the like, the aerated
liquid is forced into the bottle through the valve which opens, as aforesaid, in a
downward direction. Immediately the bottle is filled the pressure of gas closes the
valve tight against its seat. A small cover is preferably screwed down over the
screwed projection of the cover of the cap.
The covers would preferably have india rubber washers or rings in them to
ensure their closing tight.
When the covers are taken off the liquid can be poured or decanted out of the
bottle through the opening at the top of the cap.

COMPLETE SPECIFICATION.
Improvements in Bottle Stoppers.
I, GILBERT RAE, of Balbridge Works, Dunfermline, Aerated Water Manu-
facturer, 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 :-
This invention relates to bottle stoppers or caps and it has for its object to
improve the construction of such stoppers or caps.
In making my improved stopper the cap piece which fits on to the top of the
bottle is screwed, on the inside, at its lower end. Into the screwed part is inserted
an exteriorly screw-threaded ring. The ring is made or split vertically in two
pieces, one piece being, preferably, provided with projections on it which fit into
recesses or holes in the other piece. The ring fits on to the bottle neck and the

page_text: cap is screwed on to it, so bringing the pieces close together and firmly gripping
the bottle. The cap is preferably open at the top and is exteriorly screw-threaded
to receive a small internally screwed cover which, when screwed down, covers the
opening in the cap and prevents liquid escaping from the bottle. The screwed
cover has in it a small valve, the spindle of which passes out through the top of the
cover. The valve is capable of opening downwards. The valve, when the cover
is on the bottle, is held tight against its seat, which is formed in the top of the
cover, by the pressure of gas in the bottle. The valve has a rubber washer on it
or is faced with rubber so as to close tight against its seat. The outer end of the
valve spindle which has, preferably, arms or equivalent fitted to it for preventing
the valve falling through into the bottle and also to guide in its upward and down-
ward movements, works in a hollow exteriorly screwed projection on the top of the
cover. When the bottle is to be filled with aerated water and the like, the aerated
liquid is forced into the bottle, through the valve which opens, as aforesaid, in a
downward direction. Immediately the bottle is filled the pressure of gas closes the
valve tight against its seat. A small cover is preferably screwed down over the
screwed projection of the cover of the cap.
The covers would preferably have india-rubber washers or rings in them to
ensure their closing tight.
When the covers are taken off the liquid can be poured or decanted out of the
bottle through the opening at the top of the cap.
And in order that my said invention may be properly understood, I have here-
unto appended an explanatory sheet of drawings whereon:-
Fig. 1, shows the stopper in side elevation.
Fig. 2, is a vertical section of the stopper and
Figs. 3 and 4, are detail views.
Referring to the drawings;a is the cap piece which fits on to the bottle b, it is
interiorly screw-threaded at c. Into the cap is screwed an exteriorly-screw-threaded
ring d (shown in plan at Fig. 3 and side elevation at Fig. 4). This ring d is made
in two parts, one part having projections e, which fit into corresponding recesses f
in the other part. By making the ring in two parts, it can be made to firmly and
tightly grasp the bottle neck below the Leading or ledge at the top of the bottle, as
shown at Fig. 2. The cap a screws over the ring d and thus brings the two parts
firmly together so as to clasp the bottle neck. The cap is open at top where it is
exteriorly screw-threaded to receive a small internally screwed cover g. h is a
valve of any suitable construction fitted in the cover to allow liquid to be filled in
and when filled to prevent its escape. i is a rubber washer on the valve h. j are
guide arms projecting radially from the valve spindle k. is a small closing cap.
are rubber washers to prevent escape of gas.
The ring d and also the caps have, preferably, milled edges.
By simply screwing off the cap g, the liquid in the bottle can be poured out or
decanted.
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 :-
-
A bottle stopper made substantially as hereinbefore described with reference to
the drawings annexed.
