PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Infusing Tea,
I, ROBERT DAVIDSON WADDELL, of 260 North Woodside Road, Glasgow,
North Britain, Sausage Maker, do hereby declare the nature of this invention to
be as follows:
It is well known that if tea is infused beyond a certain period, not only is all
the theine extracted, but a great amount of tannin, which is very injurious to the
system. Several methods have been tried with the view of taking out the leaves
after the necessary time for infusion has elapsed one of which was to place a small
cup on the top of the tea pot, and place dry tea in this cup, but this was never a
success on account not only of there being not sufficient room for expansion of the
leaves, but also because the water did not get properly commingled with the leaves,
and so the full strength of the theine was not extracted. To overcome this I
provide a vessel of delf, or any other suitable material or metal, which reaches
almost to the bottom of the tea-pot, and is almost of the same width, and is
perforated all round, and it may be provided with a flange to rest on top of tea-pot.
This vessel is placed into the tea-pot with dry leaves, and the water poured on,
and after the six or eight minutes, the time usually allowed for the infusion, has
elapsed, the vessel is lifted out and the water passes through the perforations into
the tea-pot, so that no matter how long the infusion may be left after this no harm
will come of it as the leaves have been taken out with the vessel.
Dated this 30th day of June 1893.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Infusing Tea.
I, ROBERT DAVIDSON WADDELL, of 260 North Woodside Road, Glasgow,
North Britain, Sausage Maker, 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:-
It is well known that if tea is infused beyond a certain period, not only is all the
theine extracted, but a great amount of tannin, which is very injurious to the
system. Several methods have been tried with the view of taking out the leaves
after the necessary time for infusion has elapsed, one of which was to place a
small cup in the upper part of the teapot, and place dry tea in this cup, but this
was never a success on account, not only of there being insufficient room for
expansion of the leaves, but also because the water did not get properly commingled
with the leaves, and so the full strength of the theine was not extracted. To
overcome this I provide a vessel of delf, or any other suitable material or metal,
which reaches almost to the bottom of the teapot and is almost of the same width,
and is perforated round the sides and bottom and it is provided with a flange to
rest on top of teapot to enable it to be easily lifted out as hereinafter mentioned,
or I may have some other arrangement for lifting it out after the tea has been
infused.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended a sheet of drawing, of which A is an ordinary
teapot, and B the vessel. This vessel is placed in the teapot with the dry leaves
and the water poured on, and after the six or eight minutes, the time usually
Do17

page_text: allowed for the infusion, has elapsed, the vessel B is lifted out by the flange D,
and the water passes through the perforations C into the teapot A so that no
matter how long the infusion may be left after this, no tannin can be extracted, as
the leaves have been taken out with the vessel.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
-:
The perforated vessel A, constructed substantially as and for the purposes
hereinbefore described and shown on the accompanying sheet of drawing.
Dated this 30th day of August 1893.
