(10 nereby declare the nature of this invention to be as ToHOWS
My Invention consists in the new or improved apparatus hereinafter described for
use more particularly for making infusions of tea but which can also be used for
making infusions of other substances.
One form of my said apparatus consists of a vessel of metal, glass or other suitable
substance somewhat similar in shape to an hour glass that is to say it consists of
two bulbous parts connected together centrally by a smaller neck. The said vessel is
carried at its neck by a transverse axis with which it can be rotated in side standards
fixed to a base beneath. The two bulbous parts of the said vessel are made separate
from each other and connected together at their necks by screwing or other suitable
means so as to form a water tight joint. Beneath the said vessel I provide a spirit or
other lamp or a gas burner or other means for heating the contents of the said vessel.
One of the bulbous parts of the said vessel which for distinction I will call the upper
part contains a perforated chamber with a moveable cover for containing the tea leaves
or other substance of which an infusion is required and near the extreme end of the
other part of the said vessel, which I will call the lower part, is a tap by means of
which the contents can be withdrawn.
The apparatus as above in part described for making for instance an infusion of tea
is used as follows:-The top part of the said vessel having been removed from the lower
part the latter is filled or partly filled with water and the tea leaves are placed in the
perforated chamber in the former which is then replaced and fixed to the lower part.
When the water in the lower part has been caused to boil by the said spirit lamp
beneath or by other means the vessel is turned half round on its transverse axis. The
upper part will now be at the bottom into which the boiling water will run from the
lower part so as to cover the chamber containing the tea leaves. When the tea leaves
have been immersed in the water for a sufficient length of time say from six to eight
minutes so as to extract the aroma but not to dissolve the tannin the vessel is again

page_text: half rotated so as to bring its lower part back to its normal position into which the
infusion of tea will have run from the upper part and from which it can be withdrawn
by the said tap, it being maintained hot as may be required by the spirit lamp or other
means beneath.
In order to allow steam to escape from the vessel without any of its liquid contents
I provide at the extremity of each of the top and bottom parts of the vessel a small
opening. Each of the said openings is connected to the centre of the neck by a tube
each tube containing a spherical or other valve by which the said openings can
respectively be closed. When the vessel is in its normal position steam escapes through
the pipe in the upper part, the opening in the lower part being closed by its valve
falling thereon. When the vessel is turned in its opposite position the opening in the
upper part is similarly closed by its valve and the steam escapes through the opening
in the lower part which is then uppermost.
I provide suitable means for securing the said vessel in either position when required
such for instance as a moveable peg which passes through a hole in its axis and part
of the side standard.
Fixed to the axis of the vessel I sometimes provide one or more ordinary sand
minute glasses, which are reversed and commence to run when the vessel is turned to
immerse the tea leaves or other substance in the boiling water, by means of which the
duration of the immersion can be timed.
It will be evident that the shape of the said vessel can be modified without departing
from the nature of my Invention as it may be of a plain cylindrical or other shape and
that instead of being arranged to be rotated at the centre the axis may be fixed nearer
to one end where also the division of the two parts may be.

page_text: I, THOMAS LEWIS REEVE, of 19, New Street, Birmingham, Warwickshire, Chemist,
do hereby declare the nature of this invention and in what manner the samo is to
be performed, to be particularly described and ascertained in and by the following
statement:
My Invention consists in the new or improved apparatus hereinafter described for
use more particularly for making infusions of tea but which can also be used for making
infusions of other substances.
One form of my said apparatus consists of a vessel of metal, glass or other suitable
substance somewhat similar in shape to an hour glass that is to say it consists of
two bulbons parts connected together centrally by a smaller neck. The said vessel is
carried at its neck by a transverse axis with which it can be rotated in side standards
fixed to a base beneath. The two bulbous parts of the said vessel are made separato
from each other and connected together at their necks by screwing or other suitable
means so as to form a water tight joint. Beneath the said vessel I provide a spirit or
other lamp or a gas burner or other means for heating the contents of the said vessel.
One of the bulbous parts of the said vessel which for distinction I will call the upper
part contains a perforated chamber with a moveable cover for containing the tea leaves
or other substance of which an infusion is required and near the extreme end of the
other part of the said vessel, which I will call the lower part, is a tap by means of
which the contents can be withdrawn.
This form of my said apparatus is illustrated on the accompanying drawing in front
elevation by Fig. 1, in plan by Fig. 2, in sectional elevation by Fig. 3, and Figs. 4
and 5 illustrate how the said apparatus is used.
A is the vessel (represented on the drawing as being made of metal but it may be
made of glass or other suitable substance which will not crack when heated and is
impervious to moisture) consisting of an upper bulbous part a¹ and a lower bulbous
part a connected together at their necks by being screwed one within the other, or
by the upper part a¹ having projecting pins b, 6 which take into bayonet slots c in the
lower part a² or otherwise suitably arranged so as to form a water tight joint and be
readily removable from each other when required.
Fixed to the neck of the lower part q² is a transverse axis D with which the vessel
can be turned, carried by bearings e¹, e² in the side standards E which latter are fixed
to a base F beneath. G is an ordinary spirit lamp by which the contents of the vessel
can be heated. The upper part a' contains a perforated chamber H with a moveable
cover h for containing the tea leaves or other substance of which an infusion is required
and a tap I is provided near the bottom of the lower vessel a² for withdrawing the
contents.
The apparatus as above in part described for making for instance an infusion of tea
is used as follows:-The top part a¹ of the said vessel having been removed from the

page_text: lower part a² (see Fig. 4) the latter is partly filled with water and the tea leaves are
placed in the perforated chamber H in the upper part a' which is then replaced and
fixed to the lower part a³ (see Fig. 3). When the water in the lower part a² has been
caused to boil by the spirit lamp & or by other means the vessel is turned half round
on its transverse axis D (see Fig. 5). The upper part a¹ will now be at the bottom
into which the boiling water will run from the lower part a² so as to cover the
chamber H containing the tea leaves. When the tea leaves have been immersed in the
water for a sufficient length of time, say from six to eight minutes so as to extract the
aroma but not to dissolve the tannin the vessel A is again half rotated so as to bring
its lower part a² back to its normal position (see Figs. 2 and 3) into which the infusion
of tea will have run from the upper part a' and from which it can be withdrawn by
the said tap, it being maintained hot as may be required by the spirit lamp G or other
means beneath.
I provide suitable means for securing the vessel A in either position when required
such for instance as a moveable peg J which passes through a hole in the axis D and
part of the side standard E.
Various means may be adopted to allow the steam to escape from the vessel A with-
out any of its liquid contents escaping also but I prefer to use a small tube k which is
fixed in the neck of the upper part a¹ (see Figs. 3, 4 and 5) and through which the
steam can escape and as the vessel is so arranged that it can only be turned through
a half revolution in the direction of the arrows in Figs. 3 and 5 (a stop being provided
on the axis to limit its motion) it follows that the liquid cannot escape through the
tube k. The under side of the lower part a² is preferably made bell-shaped and radial
ribs are provided so as to form a large heating surface and at the top of the bell is a
small tube m serving as a chimney which is carried through the side of the vessel and
turned upwards (see Figs. 3, 4 and 5).
Fixed to the axis of the vessel I sometimes provide one or more ordinary sand
minute glasses, which are reversed and commence to run when the vessel is turned to
immerse the tea leaves or other substance in the boiling water, by means of which the
duration of the immersion can be timed.
It will be evident that the shape of the said vessel can be modified without departing
from the nature of my Invention as it may be of a plain cylindrical or other shape
and that instead of being arranged to be rotated at the centre the axis may be fixed
nearer to one end where also the division of the two parts may be.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :
The apparatus, for making infusions of tea or other substances, constructed and
arranged to operate substantially as described and illustrated.
