PROVISIONAL SPECIFICATION.
An Improved Tea-pot.
I, GEORGE RADFORD WILSON 1 Paul Street, Finsbury, London, E.C. do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to form a tea-pot by means of which an infusion of
tea may be prepared without the same developing tanic acid.
I form my improved tea-pot very much after the ordinary shape with sloping
sides, handle, and spout. In the centre of this outer casing I place a cylinder of
smaller diameter than the narrowest width of a tea-pot, thus a space is left
all around the cylinder. A small lid or opening is made into this outer chamber,
the object of which is to hold hot water that the cylinder or tea making compart-
ment may be hot before the tea is placed into it for infusion. The spout for
pouring out the tea passes through this outer chamber and is connected only with the
inner cylinder near the bottom of the same. At the bottom of the orifice where this
spout joins the cylinder I slightly raise the face of the cylinder above the lowest
connecting point of the spout. In the inside of the cylinder I now place an open
container for holding the tea, the height of which is sufficiently great to cover up the
outlet to the spout when the container is pushed to the bottom of the cylinder. This
container is circular on plan and sufficiently tight to work up and down inside the
cylinder and remain in any position to which it is raised, the sides of the same are
perforated and the bottom is formed in the centre in the shape of a flat truncated
cone, terminating at the top with a short tubular projection which receives and takes
into it a non-conducting rod of cane or such like material which passes up and through
the lid arranged to fit upon the cylindrical portion of my tea-pot. The afore-
mentioned conical sides of the container is perforated but the flat bottom portion of
same is solid.
A lid is arranged to fit upon the tea infusion chamber as before referred to,
pierced with a hole in the centre for the passage of the rod by means of which the
container is raised or lowered. Two knobs of non heat conducting material are
placed upon the same, one on each side to hold it down when the rod is being
raised.
I use my improved tea-pot as follows:-I first fill the outer chamber with hot
water which heats the inner cylinder, I then put the required amount of ten within
the perforated coutainer and push it to the bottom of the cylinder when it is ready
for receiving boiling water. After the tea leaves have remained in the cylinder a
little while subject to the heat I pour on boiling water and fit on the lid and when
the required amount of time is elapsed for the proper infusion of tea, 1 raise the
rod and bring the container to the top of the cylinder away from the liquid, thus
no tannic acid is developed in the tea to be consumed. Although I propose to
manufacture my tea-pots chiefly in metal I can line the cylinder with china and
the container may also be made of perforated china.
Dated this 3rd day of December 1891.

COMPLETE SPECIFICATION.
:
An Improved Tea-pot.
I, GEORGE RADFORD WILSON of 1 Paul Street Finsbury London E.C., 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:-
.
The object of my invention is to form a tea-pot by means of which an infusion
of tea may be prepared without the same producing tannic acid.
I form my improved tea-pot very much after the ordinary shape with sloping
sides, handle and spout. In this outer casing I place a cylinder of smaller diameter
than the width of the tea-pot, a space being thus left all around the cylinder. A
small opening provided with a lid is made at the top of this outer chamber, the
object of which is to hold hot water in order that the cylinder or tea making
compartment may be hot before the tea is placed into it for infusion. The spout
for pouring out the tea passes through the outer chamber and is connected only with
the inner cylinder near the bottom of the saine. In the inside of the cylinder I
place an open container for holding the tea, the height of which is sufficiently great
to cover up the outlet to the spout when the container is pushed to the bottom of
the cylinder. This container is circular in plan and fits the cylinder sufficiently
tight to be moved up and down inside the cylinder and remain in any position to
which it is raised. The sides of the same are perforated and the bottom is formed
in the centre of a conical shape terminating at its upper part with a short tubular
projection which receives a rod of cane or some bad heat conducting material,
which passes up and through the lid arranged to fit upon the cylindrical vessel.
The aforementioned conical part of the container is perforated but the flat bottom
portion is solid. A lid is arranged to fit upon the tea infusion chamber as before
referred to, pierced with a hole in the centre for the passage of the rod by means
of which the container is raised or lowered. Two knobs of suitable material are
placed upon the same, one on each side by which it may be held down when the con-
tainer is being raised. I use my improved tea-pot as follows:-I first fill the outer
chamber with hot water which heats the inner cylinder, I then put the required
amount of tea within the perforated container and push it to the bottom of the
cylinder. After the tea leaves have remained in the cylinder until thoroughly
heated I pour on boiling water and fit on the lid and when the required amount of
time has elapsed for the proper iufusion of the tea, I raise the rod gently and bring
the container to the top of the cylinder away from the liquid, thus no tannic acid
is developed in the tea to be consumed. Although I propose to manufacture my
tea-pots chiefly in metal I can line the cylinder with china and the container may
also be made of perforated china.
Referring to the accompanying drawing, which shows the invention applied to a
tin or other metal tea-pot, 1 is the outer case having handle, and spout (2), to the
top of which the cylindrical vessel 3 is fixed excentrically, being closer to the
spout end of the case than to the other. This vessel is connected to the spout by
the tube 4 passing from the inner cylinder 3 through the outer vessel, and is
provided with a lid 5 having two knobs 6 and a truncated eonical part 7 forming an
opening at its centre. At the top of the outer chamber near the handle is an
opening 8 covered by a lid, through which hot water is poured into the chamber
surrounding the inner vessel. Inside the cylindrical vessel 3 is the container formed
with a solid bottom 9, a central perforated conical portion 10, and perforated sides 11
fitting tightly against the sides of the vessel 3 and covering the opening to the
spout when in the position shown. 12 is the rod or handle of cane or other
suitable material fixed to the top of the conical part 10 and passing through the
opening 7. After the tea has been infused, the container is drawn up to the
position shown in dotted lines, remaining in that position by reason of the tightly

page_text: fitting sides 11, the tea leaves lying on the bottom and the liquid passing through
the central perforated part. The upper part of the cone 10 meets the conical sides
of the opening 7 closing the cylinder to the atmosphere and thus preventing any
escape of heated air. No leaves can pass beneath the container as there is no space
between it and the sides of the vessel 3, and thus there need be no strainer over the
spout as the perforated sides 11 serve in its place. The bottom of the spout is.
shown projecting a little lower than the tube 4 in order that any fine sediment may
collect in the recess thus formed instead of getting into the vessel or tea cup.
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 :-
:-
(1) In a tea-pot the combination of an outer case 1 to which the handle and
spout are fixed, an inner vessel 3 connected to the spout, a container fitting tightly
in the vessel 3 formed with a solid bottom 9 perforated sides 11 and perforated
conical centre 10 to which is attached the rod 12 passing through the lid 5
substantially as described and for the purposes specified.
(2) In a tea-pot the combination with the parts mentioned in the first claim of a.
conical opening 7 in the lid 5 the conical sides of which meet the upper part of the
cone 10 and prevent any escape of heated air when the container is drawn up.
