ARTHUR HART BOWMAN Jeweller, 6 Grand Promenade Brixton Road
London, Co. Surrey, do hereby declare the nature of this invention to be as
follows :—
A flat or projecting strainer of wire gause or other suitable material to which one
or more wires are attached these wires to be passed through the ordinary holes in
spout of pot (which at present forms the strainer) and drawn out at top of spout
until the new strainer is drawn closely over the old strainer or holes forming such
and then fastened around the end of the spout, this will enable a strainer to be
fastened to any pot now in existence without the pot being specially prepared to
receive it, and a perfectly clear liquor can be secured the perforations in gause being
so fine that no particles can pass through, I therefore claim a strainer which can be
fitted to any pot without cost except that of the strainer which will be nominal.

Improvements in Strainers and in the Manner of Fixing the same
in Tea and Coffee Pots or other Articles in which Infusions or
Decoctions are Prepared.
1, ARTHUR HART BOWMAN, of No. 6, Grand Promenade, Brixton Road, in the
County of Surrey, Jeweller, 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 relates to improvements in strainers for tea and coffee pots, or other
vessels in which infusions, or decoctions, are prepared; and in the manner of fixing
said strainers in such pots or vessels; and is more especially adapted to supplement
the fixed strainers in tea and coffee pots as generally made in respect of said fixed
strainers.
In carrying it into effect, I provide a cap with a flange. This is preferably and
conveniently made by stamping the same out of fine wire gauze, the cap being of
sufficient diameter to cover the fixed strainer, and concaved with reference to the
strainer for the purpose of presenting a larger practicable strainer-surface than that
possessed by the fixed strainer.
I provide (preferably two) fixing wires which are attached to the improved strainer
and are longer than the spout. These wires are passed through the fixed strainer
and made to protrude through the outer end of the spout, when they are pulled till
the flange is pulled close up to the inner surface of the pot, and then turned back
upon the spout for the purpose of retaining the flange in such position.
In order that my invention, and the best means by which the same may be carried
into practical effect, may be thoroughly understood, I will now describe the same in
detail, referring in so doing to the accompanying drawings which are to be taken as
part of this specification and read therewith.
Fig. 1 is an elevation of my improved strainer.
Fig. 2 is a sectional elevation illustrating the method of fixing such a strainer to
an earthenware teapot having a strainer of the well known kind.
A is the cap or body of my improved strainer, preferably corrugated or melon-
shaped, and a a flexible flange. B is a doubled piece of wire passed through the
centre of the cap, which it engages by the bight b. The internal diameter of the cap
is preferably not less than that of the pot-strainer, C, for the purpose of wholly
covering it. The flange, a, will therefore rest upon plain pot-surface.
To fix a strainer made according to my present invention, the ends of the wire, B,
are passed through the centre of the strainer, pushed up the spout, and drawn tight.
The pull upon the ends of the wire will make the flexible flange a engage closely
with the surface of the pot all round the old strainer C, so that no dust will be able
to get between, while the shape of the cap will prevent its being forced out of shape
by the said pull.

page_text: In the specification of a previous patent granted to me, No. 14,562, dated Novr. 10th
1886, I have described a detachable strainer adapted to be used with earthenware
pots and to be fixed therein by means of a spring clip which engages behind a
circular flange formed at the root of the spout. The invention described in said
specification requires that the pot shall be specially made for it, and the advantage
of the invention which is the subject of my present application over the one referred
to is practically this that it can be fitted in a few seconds to any teapot of either
metal or earthenware whether the latter is made with a strainer of the well known
kind, or without any strainer at all, and does not necessitate any special construction
of pot.
According to this present invention, which offers an increased area of finer strainer-
surface as compared with the well known strainer of the ordinary pot in respect both
of area and mesh, the imperfections of a coarse or damaged strainer in an ordinary
pot are at once remedied, and a perfectly clear liquor will always run from the spout
when the pot is tilted for pouring, because the fineness of the mesh prevents the tea-
leaves, or the coffee-grounds, from becoming fixed therein, and the concavity of the
strainer prevents the accumulation of leaves, or grounds, or whatever may be the
condition of the matter from which the infusion or decoction has been made, from
choking the strainer surface entirely.
Any suitable material other than fine wire gauze may be used in the manufacture
of the strainer of the present invention.
I wish it to be distinctly understood that I lay no claim to the use of a concave
strainer made of fine wire gauze, but having now particularly described and
ascertained the nature of my said invention, and in what manner the same is to bo
performed, I declare that what I claim is :-
1. The combination of strainer adapted to make close contact with the interior
plain surface of a pot or vessel around the root of the spout, and wire prongs longer
than the spout itself, adapted to retain said strainer in its position by being made.to
engage with the mouth of the spout.
2. The combination of strainer surface flange and wire prong or prongs, sub-
stantially as described with reference to the accompanying figure.
