RESERV
I, ARTHUR BOWMAN, of 472 Brixton Road, in the County of Surrey, Jeweller, do
hereby declare the nature of this invention to be as follows:-
My invention relates to tea or coffee pots or similar vessels in which an infusion
of herbs may be made and which are constructed of china, earthenware or other
ceramic ware, and consists in the application thereto with a suitable joint of a
detachable strainer of extended surface of other material than that of the pot, such
as wire gauze, perforated metallic plate, or basket work.
To carry out my invention, I make the base of the spout, where it enters the
pot, terminate in a flange, presenting a smooth surface towards the interior of the
pot, and affording a ledge around the base of the spout within which the strainer
is secured by a suitable clip.
This clip I conveniently form as a spring clip, one, two, or more spring tongues
projecting from the base of the detachable strainer. These spring tongues when
pressed together are pushed into the open mouth of the spout and springing
outwards on release engage under the aforesaid ledge of the spout.
One or more tongues may be fixed to the strainer, the opposite tongue or tongues
only springing freely; or, the engaging tongue or tongues may be spring pressed
outwards by central spiral spring between them; or, any other convenient form of
spring-clip catch, applied either to the mouth of. the detachable strainer or to that
of the spout may be used.

Improvements in Tea and Coffee Pots or similar Vessels.
I, ARTHUR BOWMAN, of 472 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 tea or coffee pots or similar vessels in which an infusion
of herbs may be made, and which are constructed of china, earthenware, or other
ceramic ware, and consists in the application thereto with a suitable joint of a
detachable strainer of extended surface, of other material than that of the pot, such
as wire gauze perforated metallic plate, or basket work.
To carry out my invention, I make the base of the spout where it enters the pot
terminate in a flange presenting a smooth surface towards the interior of the pot and
affording a ledge around the base of the spout, within which the strainer is secured
by a suitable clip.
This clip I conveniently form as a spring clip, one, two, or more spring tongues
projecting from the base of the detachable strainer. These spring tongues when
pressed together are pushed into the open mouth of the spout and springing
outwards on release engage under the aforesaid ledge of the spout.
One or more tongues may be fixed to the strainer, the opposite tongue or tongues
only springing freely.
Or the engaging tongue or tongues may be spring-pressed outwards by a central
spiral spring between them.
Or any other convenient form of spring clip catch, applied either to the mouth of
the detachable strainer, or to that of the spout, may be used.
In order to illustrate my invention I now proceed to describe the drawings here-
unto annexed, reference being had to the letters and figures marked thereon.
Figure 1 is a sectional elevation of a coffee pot, supplied with my improved
strainer.
Figure 2 is a sectional elevation of a tea pot provided with my improved strainer.
Figures 3 and 4 are equivalent but modified detailed arrangements of the joints,
by which my improved strainer is affixed.
Figure 5 is a detail of my improved strainer provided with spring clips.
In figures 1 and 2 A is the detachable strainer of extended surface and of any
suitable material fixed in the base of the spout of the pot.
In figure 3 a hole is pierced through the body of the pot to meet the base of the
spout, and so as to leave a flange B surrounding the said hole. The face of the
flange towards the pot may be conveniently recessed below the wall of the pot or
flush with it, but must be made of suitable surface so that the lower face of the
strainer shall bed uniformly upon it. The clips CC of the strainer engage under
the flange or collar B and thus secure the strainer in place.

page_text: In figure instead of providing a flat face upon which the strainer may bed, I
provide a conical face, being the walls of a conical hole pierced through the wall
of the pot to meet the base of the spout, and the clips C C₁ engage under the
shoulder of the said hole, pressing the strainer down so as to bed uniformly upon
the walls of the said conical hole. I insert my detachable strainer into these orifices
by pressing back a spring clip C³, the other clip C being conveniently a fixture,
which may be hooked over the shoulder or flange, when the strainer is inserted into
position. The strainer may be removed by pressure upon the side towards the
spring clip.
Figure 5 shows a convenient method in which I construct my spring clip. The
clip is secured to the neck of the strainer A and the clip is the extremity of
the bent U shaped spring D which passes around the inside of the strainer. In
some strainers this spring may rest lightly upon the interior of the strainer, and thus
serve to support it where it is of light material, such as gauze ; or in the larger
strainers (as in figure 5) I support the gauze envelope by a special bar E.
It is obvious that I may construct my strainer with two or more spring clips as
shown, and with both portions of the clip spring clips, instead of one being a fixture
as shown, and I may use any equivalent spring clip attachment to the neck of my
strainer which will serve most conveniently to keep it in position in the base of the
spout.
Further, although I show two specific ways in which I form the base of the spout
for the attachment of my strainer, it is obvious that without departing from the
nature of my invention I may modify the shape and formation of the orifice, so long
as the hole in the base of the spout, so prepared, presents one face upon which the
neck of the strainer may bed uniformly, and at the same time presents a face against
or under which my spring clips may grip so as to secure the strainer in place.
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 :-
1st. In an earthenware pot the construction of the base of the spout so that it
presents a face surrounding a hole towards the pot, on which the strainer may bed
uniformly, and also a face on which the spring clips of the strainer may grip,
substantially as described.
2nd. The construction of the base of the spout of an earthenware pot with a flange
surrounding a hole, presenting a flat face towards the pot upon which the strainer
may bed uniformly and a shoulder against or under which the spring clips may grip,
substantially as described.
3rd. The construction of the base of the spout of an earthenware pot with a
conical hole therein, the larger diameter being towards the pot, within which the
strainer may bed, and with a shoulder at the base against or under which the spring
clips of the strainer may grip, substantially as described.
4th. The construction of a strainer of extended surface of gauze, perforated metal,
or other suitable material, provided with clips one or more of which are spring clips
and which engage under a shoulder, or against the surface of the orifice in the base
of the spout of an earthenware pot, substantially as described.
