Offices, 18, Rue de la Chaussée d'Antin, Paris, France, and 90, Cannon Street, in
the City of London, Patent Agont, for an Invention of "IMPROVEMENTS
IN APPARATUS FOR MAKING INFUSIONS OR EXTRACTS FROM SUBSTANCES."
A communication from Arthur Voisin, of Rue de Brague, Paris, France.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents on the 8th September 1880.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18, Rue
de la Chaussée d'Antin, Paris, France, and 90, Cannon Street, in the City of
London, Patent Agent. "IMPROVEMENTS IN APPARATUS FOR MAKING INFUSIONS
OR EXTRACTS FROM SUBSTANCES." A communication by Arthur Voisin, of
Rue de Brague, Paris, France.
The Invention relates to avoiding the inconveniences presented by the tea-pots
or apparatuses intended to make infusions or extracts from substances in use up
to the present day, and which allow to pass into the cups with the outflowing
liquid the dust or particles of tea through the perforations of the diaphragm usually
soldered to the interior orifice of the neck of the tea pot, and oven through the
movable colander fixed at pleasure to the exterior orifice of the neck; further, the
Invention relates to the simplification of the manufacture of such apparatuses in
suppressing this diaphragm and the use of the said colander.
The Invention consists in combination with the teapot, properly so called, of a
cup, bowl, or receptacle whatever, and of any shape soever, made of any suitable
metal or material, into which the tea or substance to be infused is put. The sides
and bottom of this receptacle are perforated. These perforations may have any
shape whatever, and consist of slits, cuts, or holes as small and narrow as possible,
such as those of colanders for tea now in use. This receptacle is placed within the
teapot and kept in position by hooks or by any other suitable contrivance. If it is
made in the shape of a cup or bowl its upper part may be left open, and may be
closed by the lid of the tea-pot when shut. If, on the contrary, it is intended to
be plunged completely into the water poured in for the infusion it is provided with
a perforated lid, and made in such a manner as to be perfectly shut up or closed so

page_text: as not to let the water pass to its interior except through the perforations it is
provided with.
The tea or substance to be infused is put into this receptacle, which is plunged or
inserted, according to its construction, into the tea-pot or apparatus, into which, to
make the infusion, the hot water is poured, either directly into the receptacle, if
made in the shape of a cup or bowl, in which case the hot water passes through
the tea or substance to be infused to fill the tea-pot through the perforations, or at
once into the tea-pot or apparatus itself, in which case the hot water penetrates the
receptacle through the perforations to bring about the infusion of the tea or other
substance.
Having thus described the Invention, and the manner of carrying it into effect, I
claim and desire to secure by the Royal Letters Patent, in combination with a
tea-pot or other apparatus intended to make infusions without a diaphragm to the
interior orifice of its neck a receptacle, whatever its shape and arrangement may
be, provided with perforations of any convenient shape, into which the tea or
Bubstance to be infused is put and inserted or plunged into the tea-pot or apparatus,
where, to bring about the infusion, it receives the hot water directly, and which
passes through the substance to be infused, or else is surrounded and penetrated
by the hot water through the perforations, as above substantially described.
In witness whereof, I, the said Henri Adrien Bonneville, have hereto set
my hand-and-seal,-this-Sixth-day of September, in the year of our Lord
One thousand eight hundred and eighty.
