PROVISIONAL SPECIFICATION.
An Improved Stopper for Bottles, Decanters, and other similar
Utensils.
JAMES KNOWLES 24 Blenheim Terrace, St. John's Wood, Silversunith. I do
hereby declare the nature of this invention to be as follows:-
I construct a metal collar adapted to the external shape of the neck of the
bottle, decanter or other vessel, the said metal collar is fitted with an internal tube;
which tube I encase in a conical sheath or thimble of cork, rubber, or other
suitable material so that on pressing the tube into the neck of the bottle, decanter,
or other vessel, the said sheath or thimble forms an airtight joint between the neck
of the bottle & the tube. The top aperture of the said tube I construct in a
spoutal form in order to allow a free passage for the contents of the bottle,
decanter or other vessel; this aperture is sealed or rendered airtight by a cap or
cover, provided with a washer, of cork, rubber, leather or other suitable material.
The said cap, or cover is actuated by a lever fixed upon the side of the collar which
upon being gripped by the hand in the action of lifting the bottle, or other utensil
raises the said cap, or cover, and allows the contents of the bottle, or other utensil
to flow freely; beneath the said lever or in some other suitable position I fix a
spring which instantly returns the said cap, or cover to its seat upon the lever
being released-thus rendering the bottle, or other utensil airtight, and so
preventing both evaporation of the contents, and the entrance of any dust, or
foreign substances into the neck of the bottle, or other utensil.

COMPLETE SPECIFICATION.
An Improved Stopper for Bottles, Decanters, and other similar
Utensils.
I, JAMES KNOWLES, of 106 Bravington Road, Harrow Road, London, W.
(late of 24 Blenheim Terrace, London, N.W.), Silversmith, 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 invention relates to an improved stopper for bottles, decanters and other
similar utensils.
This stopper has a cap and a central tube, the exterior orifice of which is adapted
to be closed by a small lid or cover furnished at the end of a lever which is pivoted
to the said cap. The free arm of this lever, which is under the action of a spring
designed to keep the orifice of the tube normally closed, extends along the neck of
the bottle or other utensil, and can thus be acted upon with the hand when taking
hold of the neck, thereby uncovering the aforesaid orifice for pouring liquid from
the bottle or the like.

page_text: In the accompanying drawing I have shown by way of example how my inven-
tion may be carried into practice, but it will be understood that I may vary the
forms of the several parts of the stopper without departing from the nature or
scope of my invention.
The improved device comprises the stopper a of cork or other elastic material,
held in a cap & made of any appropriate form. A central tube c extends through
the stopper a and cap b and is cut on the slant at its end. The orifice thus formed
is closed by a lid or cover d preferably provided at its under surface with an
elastic pad to make a tight joint. This lid or cover is arranged at the extremity
of a lever e pivoted at f to the cap b, the free arm of this lever extending along
the neck of the bottle or utensil. By means of any suitable spring acting
upon the lever e the lid or cover d is normally held upon orifice of the central
tube c.
When liquid is to be poured from the bottle or utensil I take hold of the neck
of the latter, and press simultaneously upon the lever e to open the orifice of the
central tube. This orifice will be automatically closed again on releasing the said
lever, thus precluding any access of dust or the like to the interior of the bottle or
other utensil.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
In stoppers for bottles, decanters and other similar utensils the combination, with
a tube c extending through the stopper a, of a lid or cover d and pivoted lever e
under the action of a spring, substantially as set forth.
