GEORGE JAMES CHAMBERS 59 South Lambeth Road Vauxhall Surrey Potters
Foreman do hereby declare the nature of this invention to be as follows:-
My improvement consists in providing on the interior of the mouth of vessels,
three or any convenient number of slots or grooves, preferably tending downwards
in a spiral direction, with a ward or aperture at the commencement of the upper
end of each slot or groove sufficiently large to admit the easy insertion of corre-
sponding projections on the stopper.
The stopper is provided with an india-rubber, or other suitable washer, and
slightly below this, are the projections above mentioned, which are formed of some
strong and suitable material to prevent breakage, and which easily enter the wards
at the commencement of the grooves as above described.
A very slight rotation of the stopper, through a portion only, of the circumference
brings the washer into airtight contact with the mouth of the vessel.
A corresponding slight turn, in the opposite direction, completely releases the
stopper.
A perfectly airtight stoppering with simplicity of parts and rapidity of manipu-
lation, are the advantages claimed for this invention.

I, GEORGE JAMES CHAMBERS, Potters Foreman, 59 South Lambeth Road
Vauxhall Surrey do hereby declare the nature of my invention for AN IMPROVE-
MENT IN STOPPERING BOTTLES USED FOR GINGER BEER, ALE, STOUT & THE LIKE
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My improvement consists in providing on, the interior of the mouth of vessels,
three or any convenient number of slots or grooves, preferably tending downwards
in a spiral direction, with a ward or aperture, at the commencement of the upper
end of each slot or groove, sufficiently large to admit the easy insertion of corre-
sponding projections on the stopper.
The stopper is provided with an india-rubber, or other suitable washer, and
slightly below this are the projections, above mentioned which are formed either in
one with the stopper or may be made separatly of some other suitable material
and then fastened on to the stem of stopper These projections easily enter the
wards or grooves as before described.
A very slight rotation of the stopper through a portion only of the circumference
brings the washer into airtight contact with the mouth of the vessel.
A corresponding slight turn in the opposite direction completly releases the
stopper.
In order to prevent the liquid contained in the bottle from coming into contact
with the india-rubber washer I make another stopper with a slight alteration in
its shape without altering its principle.
Viz The stem is elongated so as to take a cork ring below the projections or at
the extremity of the stopper Then by making the throat of the bottle narrower
inside, a shoulder is formed which will come into contact with the cork ring on
stopper, when it is fastened in its place thereby preventing any liquid from
escaping till the stopper is removed from the bottle.
A perfectly airtight stoppering with simplicity of parts & rapidity of manipu-
lation are the advantages.claimed for this invention.
Fig. 1 of the drawing gives a perspective view of the mouth of vessel looking
down, and shewing three spiral slots, with a ward or aperture leading to each.
The stopper with washer and projections is shewn in elevation above.
Fig. 2 shows in section, the. position of stopper, when in use in vessel.
Fig. 3 is a plan of stopper, from, the under side shewing position of projec-
tions &c.
Fig. 4 shews in section the other stopper, & top of bottle, with the cork
arrangement as before described, No. 1 is the cork on shoulder of bottle, No. 2 is the
india rubber washer.
Fig. 5 shows an elevation of the same stopper, with the cork ring fixed upon it
Fig. 3 answer's also for a plan of this stopper.

page_text: Fig. 6 shows in elevation, an alternative stopper, with two or four projections,
to be used with a two or four grooved mouth, if preferred.
Having now particularly described, and ascertained, the nature of my said inven-
tion, and in what manner the same is performed, I declare that what I claim is
First. The formation on the interior of the mouths of vessels, of hollow grooves
or slots, preferably tending downwards in a spiral direction, through one third or
other convenient parts of the internal circumference of mouth, with a ward or
aperture, forming an entrance to each groove, as described.
Secondly. The use, in combination with such grooves, of a stopper with corre-
sponding projections as described, and with a washer, capable of being brought by
a part of a rotation of the stopper, into airtight contact, with the mouth of vessel.
Also the right, if desired, of adding the cork ring, on the extremity of the
stopper, as before described.
