PROVISIONAL SPECIFICATION.
An Improved Strainer for Teapots, Coffee Pots, Tea Urns, and
the like.
FREDERICK MANN 20 Atherton Road Forest Gate Essex Mercantile Clerk, do
hereby declare the nature of this invention to be as follows:-
My invention relates to the strainer by which tea leaves, coffee grounds &c.
are prevented from passing through the spout into the cup when the infusion is
poured off.
My invention consists of the pot being divided into two sections by means of a
partition in which a space is left, either round square or of other suitable shape-
into this space
is fitted a double framed strainer made of woven wire, perforated
metal, muslin, net, or the like material, so fixed that the two frames interlock & so
hold them in position.
The strainer being removable is easily cleaned & does not obstruct the cleaning
of the pot & further admits of the strainer being renewed as often as required.

the like.
I FREDERICK MANN of 20 Atherton Road, Forest Gate, London, Mercantile
Clerk, 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 is designed to secure the highest attainable amount of efficiency
and convenience in the straining of tea or coffee, and avoid all danger of choking the
spout of the vessel while ensuring the necessary extraction of flavour from the
material operated on.
It consists of two main parts a vertical or nearly vertical partition inserted in
the vessel in which partition is an aperture and a moveable strainer to fit into said
aperture.
The partition is fixed and it extends from the bottom of the vessel to the neck
or top, or so high that there is no danger of liquid, passing over it when the pot is
tipped or inclined for pouring. The aperture may be round, square or of any
preferred outline, but by preference I make it oval as shewn in the annexed
drawing.
The straining medium may be fine gauze metal wire or of some woven material
such as muslin or net, or in the case of coffee, gauze wire and woven material
combined.
By preference employ a woven wire strainer of platinum or aluminium or some
metal or alloy which is not readily oxydisable, or a strainer which is coated with

page_text: I also prefer to employ an extremely fine mesh, so that tea dust when swollen
with moisture will not readily pass through it.
An important feature of my strainer is that it is readily removable for cleaning
or renewing.
I will now describe the invention" with reference to the accompanying drawings
in which,
Fig. 1 shows a perspective elevation of a teapot constructed on my system, with
the front removed.
Figs. 2 and 3 show plan views of both sides of my strainer which is by preference
constructed of two parts as-shewn.
Fig. 4 shows a side elevation of one part of my strainer showing clips or lugs c².
Fig. 5 is a detail partial sectional elevation enlarged showing method of fastening
the two parts of my strainer together.

care flexible lugs which being turned back hold the strainer in place.
d, is a flanged collar placed on the reverse side of the aperture over which the
lugs are bent.
This flange can be dispensed with if preferred and the lugs bent over the edge
of the aperture.
To remove the strainer these lugs must be unbent.
It will be seen that the partition divides the interior of the pot into two chambers
with the strainer affording a means of communication between them.
The tea or coffee is placed in the chamber behind the strainer which is the one
distant from the spout. The hot water is then poured on it and as it becomes
infused the infusion passes into the front chamber whence it is poured out for use.
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 :-
In a teapot, coffee pot, tea or coffee urn or the like, a fine removable strainer
inserted in a fixed partition as herein described and set forth.
