PROVISIONAL SPECIFICATION.
Improvements in Valves or Stoppers for Tea Infusers.
JOHN CRABTREE Witham Lodge Bracebridge Lincoln, Railway Official, do
hereby declare the nature of this invention to be as follows:-
Referring to my Application No. 14717/94 for Patent for "Improvements in
appliances for controlling or regulating the time of infusion of tea," I now make
application for improvements in the valves or stoppers described therein.
In addition to the arrangement included in my previous Specification, I provide
another, or varied, method of stopping, or regulating, the flow of liquid from the
infuser to the outer tea pot or tea urn.
The main feature of the improvement is in constructing the round strainer, or
lift, with two round or conical shaped studs, or feet. These studs fit over, or into,
When the studs are
two holes of corresponding size in the bottom of the infuser.
in, or over, these holes the communication between the infuser and the outer vessel
is closed. To open the holes, or outlet, to allow of the passage of liquid from the
infuser, the strainer is raised and slightly turned by means of the knob of rod
When this is done
reaching up to the level of, or outside, the lid of outer vessel.
the studs rest on the solid bottom of the infuser, and act as feet to support the
strainer sufficiently high to allow the free passage of liquid from the infuser,
through the perforations in strainer, into the outer vessel.
To ensure a water tight closure of openings at bottom of infuser, I place on the
neck of each of the round, or conical, studs, or feet, a circular washer of pure
rubber which makes a close fitting joint.
The advantage of this arrangement as against the flat, or slide valve 18 in
removing any difficulty-particularly in the case of the construction in china or
earthenware in making the whole of the bottom of infuser and of strainer
sufficiently level to fit true.
The two round studs, or feet, (sometimes called stoppers) will more effectually
close the aperture, or apertures, and prevent leakage.

COMPLETE SPECIFICATION.
Improvements in Valves or Stoppers for Tea Infusers.
JOHN CRABTREE Witham Lodge Bracebridge Lincoln, Railway Official, 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:
Referring to my Application No. 14717/94 for Patent for improvements in
appliances for controlling or regulating the time of infusion of tea, I now make
application for improvements in the valves, or stoppers, described therein.
In addition to the arrangement included in my previous Specification, I provide
another or varied method of stopping, or regulating, the flow of liquid from the
infuser to the outer tea pot or urn.
The main feature of the improvements is in constructing the round or oval
strainer, or lift, with two round or conical shaped studs or feet. These studs fit
over, or into two holes of corresponding size in the bottom of the infuser.
When

the studs are in, or over, these holes the communication between the infuser and
the outer vessel is closed. To open the holes, or outlet, to allow of the passage of
liquid from the infuser, the strainer is raised and slightly turned by means of the
knob of rod reaching up to the level of, or outside the lid of outer vessel.
this is done the studs rest on the solid bottom of the infuser and act as feet to
support the strainer sufficiently high to allow the free passage of liquid from the
infuser, through the perforations in strainer, into the outer vessel.
To ensure a water tight closure of openings at bottom of infuser, I may place
on the neck of each of the round or conical studs, or feet, a circular washer of
pure rubber, which makes a close fitting joint.
The advantage of this arrangement, as against the flat or slide valve, is in
removing any difficulty-particularly in the case of the construction in china or
earthenware in making the whole of the bottom of the infuser, and of strainer,
sufficiently level to fit true.
The two round studs, or feet, (sometimes called stoppers) will more effectually
close the aperture, or apertures, and prevent leakage.
Instead of two studs, or stoppers, one only may be used, and in that case it is
placed under the centre of the strainer, forming a combined stopper and strainer,
and there is one hole, or socket, in the bottom of the infuser in a corresponding
position.
DESCRIPTION OF DRAWINGS.
Figure 1. shews in section a tea pot containing the infuser "D." There is a
single plug, or stopper, "B," forming part of the strainer. This plug is in the
centre and fits into a hole, or socket, in a corresponding position in the bottom of
the infuser.
The holes "C" are to allow liquid to escape into the tea pot in case of
overflow.
Figure 2. gives an illustration of a strainer with two studs or plugs "A." In
this case there are two holes, or sockets, in the bottom of the infuser.
The operating knob is shewn in both figures as under the lid, but it may be so
arranged as to be operated outside the lid."
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
The introduction, or application, of a stopper, or stoppers, in combination with
a tea strainer in infusers, within tea pots or tea urns, in the manner and for the
purposes already described.
Dated this 30th day of October 1894.
