Improvements in Apparatus for Making Infusions of Tea and other
like Infusions.
I, FREDERICK HALL of 43 Suffolk Road Sheffield in the County of York Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
My invention of improvements in apparatus for making infusions, is especially
adapted for use in connection with Teapots, and has for its object to improve upon
the present methods used for such purposes, both in convenience, facility, cleanliness,
and result; it may also be applied to other like vessels for infusing.
In carrying out my invention in its application to an ordinary teapot (for example)
I make a cylindrical vessel of suitable metal, its lower part being made to fit into the
opening in the pot from which the lid is removed; and which is made to fit the top
of the vessel and to serve as its cover during its temporary use in the position
described; an outside ring or like projection retains the vessel at the proper height
above the top of the teapot.
The vessel is open at the top, but near the bottom it is closed by a floor or diaphragm
of the same metal, having a central opening made to act as a valve seating.
A valve of corresponding shape to fit into and close the valve seating, is attached to
a long tubular rod open at the top and bottom, and passing through the valve before
mentioned and upon the said tubular valve rod, 1 place one or more, (but preferably
two) grates or sieves, made to slide easily upon the valve rod, and to fit the interior
of the vessel.
:
Each grate or sieve is made with a rim, the lower one being shallow and the top one
deep, the bottom sieve rests upon the top side of the valve, and the top sieve rests
upon the top edge of the rim of the bottom sieve.
It is used as follows-the apparatus is placed in position in the opening of the tea-
pot, the valve resting in, and closing the valve seat; the sieves also being in their
lowest position; Tea is put into the top sieve, and water is then poured in, and the
teapot lid put on the top, until the infusion is considered to be complete; the lid is
then removed and the valve raised, which permits the liquid infusion to pass through
into the teapot.

page_text: After the clear infusion has passed through the valve into the pot, the vessel may be
- removed and the lid be replaced.
Although I have described the valve as being raised and opened by a vertical
movement of the tubular rod, I do not bind myself to this particular construction, as
it may be easily constructed to open and close, by a partial rotary movement, or
otherwise.
The valve rod is made tubular, to permit the escape of air when the infusion is
passing through the valve into the teapot.
COMPLETE SPECIFICATION.
Improvements in Apparatus for Making Infusions of Tea and other
like Infusions.
I, FREDERICK HALL of 43 Suffolk Road Sheffield in the County of York
Manufacturer 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 :-
My invention of improvements in Apparatus for making infusions, is especially
adapted for use in connection with Teapots and it has for its object to improve upon
the methods at present in use for the same operation, both as regards facility, and the
result attained; it may also be applied to other vessels for making infusions.
In carrying out my invention in its application to a Teapot, for example, in the
manner illustrated in the annexed sheet of drawings, I make a cylindrical vessol A of
suitable material such as Britannia motal for example, its lower part B, being made to
fit into the opening of the Teapot C, from which the lid D, is removed and made to
serve as a temporary cover for the apparatus during its uso in the Teapot.
An outside ring E, or other like device rests upon the edge of the pot and retains
it in its proper position as shown.
The apparatus or vessel is closed near the bottom by a diaphragm of motal F,
having a central opening G, which is constructed to act as a seating for a valve, but I
do not bind myself to any precise configuration of opening or valve.
I prefer however to use a conical valve H, as shown fitting into a conical seating,
opening and closing by a vertical movement, it is attached to a tubular rod 1, open at
both ends so as to form an air passage through the valve into the body of the
Teapot.

page_text: Upon the valve rod I, but not attached thereto, I place one or more (but preferably
two) grates or sieves J and K, through the centres of which the valve rod can slide
easily.
The outside rims of the grates or sievos J & K, fit against the inside of the
cylindrical vessel A, and preferably the deep top rim of J, fits upon or inside the
shallower rim of K.
The sieve J is made with a coarser or more open mesh than that of the sieve K.
When the apparatus is placed in the opening of the teapot, the valve rests upon
the seating and closes the opening G, tea is put into the top sieve, and after water is
poured into the vessel, the lid put on as shown until the infusion is considered to be
complete, when the lid is removed and the valve raised permitting the liquid infusion
to pass through into the teapot. After the clear infusion has passed into the teapot,
the infusing vessel is removed and the lid replaced.
The valve rod being made tubular permits the escape of air when the infusion is
passing through, the valve into the Teapot."
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 1
claim is :-
1. The improved apparatus for making infusions, constructed substantially in the
manner as hereinbefore described and illustrated in the drawings.
2. An apparatus for making infusions consisting of a vessel A, a diaphragm F,
an outlet G, a valve H and one or more sieves J or K, constructed and arranged
substantially as described and shown.
