WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN DEVICES FOR STOPPERING
BOTTLES AND OTHER VESSELS." A communication from abroad by Fredrik
Bohman, of Stockholm, Sweden.!
This Invention relates to improved devices for closing the mouth of bottles or
other vessels by means of stoppers or covers of glass, china, metal, or other suitable
material.
A stopper embodying this Invention has a flange which surrounds the neck of
the bottle or other vessel, or is surrounded thereby, and the stopper as well as
the vessel may in some cases be polished. For better ensuring that the stopper
should fit tightly a piece of cork, india-rubber, or similar material, may be inserted
between the stopper and the bottle, or wax or other similar substances may be used
for this purpose. The stopper is convex at its upper side, and is held in contact
with the bottle by a bow shaped piece being turned or pushed over the stopper;
the said bow-shaped piece has at its centre a bend extending downwards and
entering a small concavity or depression in the top of the stopper. The bow is
fastened to and has its fulcrum at the top of the neck of the bottle or other vessel
to which this Invention is applied.
According to a modification, the stopper above described may be used instead
of a syphon for aërated waters, or the like, and this arrangement allows a part of
the beverage contained in the vessel to which it is applied to be poured out whilst
preventing the escape of the gas contained in the rest of such beverage. For this
purpose a hole or aperture passes through the stopper, a valve being provided for
allowing the said aperture to be opened or closed as required.
In carrying this part of my Invention into practice I prefer to make the body
of the stopper of metal, a suitably arranged valve therefor consisting of a disc
closing the aperture above mentioned, and being attached to a piece extending
through the stopper; the said piece is provided with a stud or head for operating
the same, and the stud is surrounded by a coiled spring to ensure tight closing of

stopper is put on and the liquid is caused to enter at the opening, through which
it afterwards is allowed to escape, this aperture being by a tube connected with
the reservoir from which the liquid is supplied. The air in the bottle escapes when
the bottle is being filled through another hole, which is afterward closed by a
suitable valve provided for the same. The valves and the opening for pouring
out the fluid may have any suitable form.
Both the above described forms of stopper are held in place by a bow-shaped
piece as stated, the ends of the bow-shaped piece being inserted in holes on the
outside of the neck of the bottle, which may be so made that the outer side of
their upper margin extends beyond the inner side, by which arrangement it is
easy to fasten the bow safely.
Provision may also be made for a second bow-shaped piece which would pass
over the first bow. By this arrangement the stopper will when taken out of
the mouth of the bottle be retained upon the bottle by the principal bow.
