PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Making Tea, Coffee, Cocoa, and
like Infusions.
I, ALFRED ALEXANDER WEBBE, of 44 Clive Road, West Dulwich, in the
County of Surrey, Architect, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in apparatus for making tea, coffee,
cocoa, and like infusions, and consists in so constructing the same that all parts of
the interior are readily accessible for the purpose of cleaning, and also to prevent
leakage at the lid.
It is found in use that a deposit or scale collects about the inside of these vessels
and renders repeated cleaning necessary. Now though the inside of these vessels
may be readily cleaned it is found to be impossible to clean the inside of the spout
and front side of the strainer as access to these parts cannot be obtained.
According to one method of carrying my invention into practice I form an
opening at the lower end of the spout in immediately close proximity to the strainer,
through which the cloth or other cleaning implement may be passed to remove the
deposit from the interior of the spout and face of the strainer. This opening is
closed by a screw cap, or plug, or other suitable stopper.
According to another arrangement I make the spout itself detachable and
connected to the vessel by means of a screw thread or bayonet or other suitable
joint employing a suitable elastic washer to make a tight joint between the parts.
According to another arrangement I form a perforated cage of cylindrical or
other form inside the vessel and over the opening communicating with the spout.
In this cage I form a large opening closed by means of a screw stopper or other
suitable device and through which a cloth or other implement may be passed to
clean the inside of the spout and strainer.
To prevent leakage at or around the lid or cover 1 form the same with a screw
thread to engage with a thread around the opening in the top of the tea pot. This
screw joint I make water-tight by means of an india-rubber or other suitable
washer.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Making Tea, Coffee, Cocoa, and
like Infusions.
I, ALFRED ALEXANDER WEBBE, of 44 Clive Road, West Dulwich, in the
County of Surrey, Architect, 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 :-
This invention relates to improvements in apparatus for making tea, coffee,
cocoa, and like infusions, and consists in so constructing the same that all parts of
the interior are readily accessible for the purpose of cleaning, and also to prevent
leakage at the lid.
It is found in use that a deposit or scale collects about the inside of these vessels
and renders repeated cleaning necessary. Now though the inside of these vessels

page_text: may
be readily cleaned it is found to be impossible to clean the inside of the spout
and front side of the strainer as access to these parts cannot be obtained.
According to one method of carrying my invention into practice I form an
opening at the lower end of the spout in close proximity to the strainer, through
which the cloth or other cleaning implement may be passed to remove the deposit
from the interior of the spout and face of the strainer. This opening is closed by
a screw cap, or plug or other suitable stopper.
According to another arrangement I make the spout itself detachable and
connected to the vessel by means of a screw thread or bayonet or other suitable
joint employing a suitable elastic washer to make a tight joint between the parts.
According to another arrangement I form a perforated cage of cylindrical or
other form inside the vessel and over the opening communicating. with the spout.
In this cage I form a large opening closed by means of a screw stopper or other
suitable device and through which a cloth or other implement may be passed to
clean the inside of the spout and strainer.
To prevent leakage at or around the lid or cover I forin the same with a screw
thread to engage with a thread around the opening in the top of the tea pot. This
screw joint I make water tight by means of an india-rubber or other suitable
washer.
And in order that this invention may be more readily understood and carried
into practice, I will now proceed to describe the same with reference to the
accompanying four sheets of drawings illustrative of my said invention.
As shown at Fig. 1 the tea pot is provided with a perforated strainer a at the
base of the spout in the ordinary manner. The spout is provided with an opening b
at its junction with the body of the pot so that a brush, cloth or other device may
be inserted to clean the strainer a. The opening b is closed with a stopper consisting
of two plugs of earthenware or other suitable material which are grooved to receive
between them an india rubber or other suitable elastic washer d and arranged to be
drawn together by means of a screw pin e to expand the washer and completely fill
the annular flange lying round the opening b as will be readity understood from an
inspection of the drawings. The spout has a detachable end piece which is fitted
into a socket and made to secure a second strainer g of fine gauze which will
prevent the passage of any tea leaves or other solid matter that may pass through
the strainer a. It will be seen that the strainer g may be readily removed for the
purpose of being cleaned.
As shown at Fig. 2 the opening b is closed by means of a screw stopper c fitted
with an elastic washer d.
At Fig. 3 the tea pot is made with a strainer formed in the end of a thimble like
piece a inserted in the end of the spout from the inside of the tea pot. A second
shallow perforated thimble is first inserted in the spout, a suitable washer c being
employed to make a tight joint. It will be readily understood that the strainer b
acts to stop the passage of any particles escaping the strainer a.
In Fig. 4 the strainer a is itself provided with an opening closed by a screw
plug b so that it may be cleaned from the inside of the pot. This figure also shows
an alternative position for the stopper which in this case closes the opening in
the side of the body of the pot. If preferred this opening may be disclosed by
removing the spout which is here shown removable and fitted with a second strainer
of gauze or other suitable material.
Fig. 5 shows a similar method of attaching the spout, making the same secure a
second strainer b in position.
Fig. 6 shows a modified arrangement of the stopper shown at Fig. 1.
Fig. 7 shows another method of preventing the passage of tea leaves in the
spout. In this case two cup like strainers of perforated earthenware or other
suitable material are suspended from the opening in the pot. As is shown in the
drawing the upper strainer a lies within the mouth of the lower strainer both being
flanged to rest within the mouth of the strainer. The lower strainer may be
employed for infusing coffee or the like. In order to prevent the tea running over

page_text: the top of the tea pot and on to the table cloth I make the lid c to screw to the
mouth of the tea pot as shown, and make a tight joint between the parts by means
of a suitable washer d of india rubber or other inaterial.
A modified arrangement of this form of lid is shown at Fig. 9 from which it will
be seen that the washer d is placed around the lid c instead of around the mouth of
the tea pot.
Fig. 8 shows a method of making a tight joint between the lid and the mouth of
the pot substantially similar to the arrangement shown at Figs. 6 and 7 the only
point of difference being the employment of a spring to press the two parts of the
lid apart.
Fig. 10 illustrates a similar form of lid hinged to the tea pot.
Figs. 11 and 12 show a peculiar construction of the rim of the lid to adapt it
for use with an elastic washer.
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 :-
(1) The hereinbefore described improvements in the construction of strainers for
tea pots and the arrangement of the same to facilitate the process of cleaning,
substantially as and for the purpose hereinbefore described and set forth and
illustrated in the accompanying drawings.
(2) The hereinbefore described means for preventing the escape of liquid round
the lids of tea pots and the like infusors, substantially as and for the purpose
hereinbefore described and set forth and illustrated in the accompanying drawings.
