COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville at the
Office of the Commissioners of Patents on the 3rd May 1877.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18, Rue
de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the County of Middlesex,
Patent Agent. "A NEW OR IMPROVED TEAPOT." (A communication by Arthur
Voisin, residing at 18, Rue de la Chaussée d'Antin, Paris, France aforesaid.)
The Invention relates to suppressing the use of the moveable percolators or
colanders fixed to the spout of the neck of teapots, in order to intercept the passage
of the dust or particles of tea leaves when the liquid is poured into the cups, and to
making teapots without the grate or perforated diaphragm fixed to the inner orifice
of the neck.
The Invention consists in combining with the teapot, whatever may be its shape,
a moveable filter or perforated receptacle, placed inside and dipping into the teapot.
This apparatus suspended by an annular flange at the upper part thereof, which
rests on the circular cavity, into which the edge of the teapot lid is set, without
offering any obstacle to the tight closing of the latter.
The Invention is illustrated in the accompanying Drawings, in which Fig. 1 is a
central section in elevation of a teapot provided with the said filter; Fig. 2, a vertical
central section of the latter; and Fig. 3, a top plan view of the same.
In these Figures similar letters indicate corresponding parts.
a is the body of the teapot; b, the filter or receptacle into which the tea is
thrown; c, the annular flange of the filter; d, the circular groove or cavity around
the aperture of the body of the teapot, and upon which rests the annular flange
of the filter, and above the said flange is lodged the circular rim of the lid e when
the latter is closed.

page_text: It will thus be seen that the combination of the moveable filter and the teapot
allows, as has been already stated, of doing away with the percolator or colander,
and the filter or perforated diaphragm or partition fixed inside at the entrance to
the neck of the teapot. The said diaphragm has the disadvantage of becoming
obstructed, and of preventing the liquid from running through easily; the very
inconvenient percolator or colander, which is fixed more or less firmly to the spout
of the neck of the teapot, slips to one side or the other under the weight or stream
of the liquid, and the tea leaves or dust pass over its flange, and fall into the cup.
The new or improved filter obviates these disadvantages, and has the advantage
of being kept firmly in its position, and of being tightly closed when the lid of the
it entirely
teapot is shut; it does not allow a single leaf or any tea dust to escape;
detaches the tea from the mass of liquid contained in the teapot, and at the same
time leaves the tea in contact with the water until the liquid contained in the tea-
pot is drained off, its lower extremity almost extending to the bottom of the teapot.
The wide superficies presented by the bottom and compass of the filter allows of
making numerous perforations or slots therein, and of making them extremely small
or fine, so that the passage of the liquid from the filter into the body of the teapot
is easily and quickly effected, whilst a complete bar is opposed to the passage of the
dust or tea leaves.
Having thus described the said Invention I would have it understood that I do
not confine myself to the precise details above enumerated, as the shape, the materials
employed, and the application of the said Invention may obviously be modified
according to circumstances without departing from the principles upon which the
same is based, for what I claim and desire to secure by the Royal Letters Patent
is,―
1st. The doing away with the use of the tea percolator or colander and of the
filter or inner diaphragm of teapots.
2nd. The combination with the teapot of a filter or perforated receptacle placed in
the inside of the teapot, substantially as above described and represented in the
accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto set my
hand and seal, this Twelfth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
