Year: 1880

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine, Lake,
& Co., Patent Agents, Southampton Buildings, London, for an Invention
of "IMPROVEMENTS IN STOPPERS FOR BOTTLES OR JARS." A communication
from abroad by Franz Koeller, of Neulengbach, near Vienna, Austria, Doctor
of Medicine.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 30th March 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "IMPROVEMENTS IN STOPPERS FOR
BOTTLES OR JARS." [A communication from abroad by Franz Koeller, of
Neulengbach, near Vienna, Austria, Doctor of Medicine.]
This Invention relates to improvements in stoppers for bottles or jars.
A stopper constructed according to this Invention is composed of two parts,
namely, a shaving or shavings or fibres of wood rolled to a cylindrical or conical
form, and a capsule of ductile material into which the said roll is inserted.
The stopper is inserted into the neck of the bottle or jar in such a manner that
the end covered by the capsule comes foremost into the neck, so that the fluid
contained in the bottles or jars comes into contact only with the surface of the
metal capsule.
For general purposes the metal of which the capsule is made may be tin, but for
stoppers for bottles or jars containing alkalies capsules of iron conted with silver,
or capsules of silver alone, may be used, whilst for bottles containing sulphuric or
hydrochloric acid the capsule may be made of lend.
By reason of the shaving or shavings or fibres of the wood being rolled to a
cylindrical or conical form, and the capsule containing the same being of a ductile
metal, the stopper will adapt itself to the form of the neck of the bottle into which
it may be inserted, and as only the metal surface of the capsule will be presented
to the fluid contained in the bottle the fluid cannot be contaminated by the stopper,
and the stopper cannot absorb or be affected by the said fluid.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Robert Lake in the Great Seal Patent Office on the 28th
September 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN STOPPERS FOR BOTTLES OR
JARS." A communication from abroad by Franz Koeller, of Neulengbach, near
Vienna, Austria, Doctor of Medicine.
This Invention relates to improvements in stoppers for bottles or jars.
The stoppers constructed according to this Invention are composed of two parts,
viz., the interior formed of a shaving or shavings or fibres of wood rolled or coiled
toa.cylindrical or conical form, and the exterior consisting of a capsule of ductile
metal, into which the said roll or coil is inserted.
In the accompanying Drawing,-
Figure 1 is an elevation ;
Figure 2 is a vertical section and
Figure 3 is a horizontal section, of a stopper constructed according to this
Invention.
a is the shaving of wood rolled or coiled to a somewhat conical form; b is the
metal capsule covering the bottom and side surfaces of the said roll. This coil or
roll is inserted into the capsule, and the whole constitutes the stopper.
For general purposes the metal of which the capsule is made may be tin, but for
stoppers of bottles or jars which are to contain alkalies capsules of iron coated with
silver, or capsules of silver may be used, whilst for bottles to contain sulphuric or
hydrochloric acid the capsule may be made of lead; or the said capsule inay be
made of other material, according to the purpose for which it is intended. The
dimensions and form of this stopper need not be those represented in the Drawing,
but may be varied to suit different purposes.
The said stopper is inserted into the neck of the bottle or jar in such a manner
that the end covered by the bottom of the capsulo comes foremost into the neck, so
that the fluid contained in the bottle or jar comes into contact with the surface of
the metal capsule only, and not with the wood or other fibrous material.
By reason of the shaving or shavings or fibres of wood being rolled or coiled to a
cylindrical or conical form, and the capsule containing the same samo being of a
ductile metal, the stopper will adapt itself to the exact form of the neck of the
bottle or other vessel into which it may be inserted, and as only the metal surface
of the capsule will be presented to the fluid contained in such bottle or vessel the
fluid connot be contaminated by the stopper, and the stopper cannot absorb the
said fluid or be affected thereby.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performning the same, I wish it under-
stood that I claim,-
A stopper constructed with a shaving or shavings or fibres of wood rolled or
coiled into a cylindrical or conical form, and inserted into a metal capsule,
substantially as described and shewn in the Drawings, and for the purposes
pocified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and scal, this Twenty-fifth day of September, in the year of our Lord
