PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Measuring Exact Quantities of
Heated or Boiling Water for Tea and Coffee Testing and
other similar Purposes.
1, GILES SEDDON of 34 Loampit Vale Lewisham in the County of Kent, Grocer, do
hereby declare the nature of this invention to be as follows:-
My invention for improvements in apparatus for measuring exact quantities of heated
or boiling water for tea and coffee testing and other similar purposes has for object to
provide improved means for accurately admitting the same predetermined quantity of
heated or boiling water to the different samples of tea or coffee or other article to be
tested.
•
In carrying my invention into practical effect, one end of a cock or tap is secured
in the side of a kettle or other similar apparatus for heating water. The other end of
the said tap is secured in a cylinder of the exact capacity required. Another tap is
secured in the hotton of the said cylinder. At the top, the cylinder is provided with
a small hole or vent, the side of the cylinder projecting beyond its top. A small waste
pipe leads away from the lowest point of the receptacle thus formed at the top of the
said cylinder, it may be to any suitable vessel or receptacle.
In the operation of testing tea or coffee, the tap secured to the kettle is turned on so
that the boiling water enters the said cylinder and is closed as soon as the said cylinder
is full which is indicated by the escape of water from the vent or from the waste pipe.
The tap at the bottom of the said cylinder is then turned to admit the water in the
cylinder to the tea or coffee.
It will readily he seen that all the different samples of tea or coffee receive exactly
the same predetermined amount of water.

I, GILES SEDDON of 34 Loampit Vale, Lewisham, in the County of Kent, Grocer,
do hereby 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 for improvements in apparatus for measuring exact quantities of
heated or boiling water for tea and coffee testing and other similar purposes has for
object to provide improved means for accurately admitting the same predetermined
quantity of heated or boiling water to the different samples of tea or coffee or other
article to be tested.
In carrying my invention into practical effect a cylinder or other suitable vessel is
fixed within a kettle or other similar apparatus for heating water and is provided with
two cocks or taps and with a small hole or vent at its top communicating by means of
a waste pipe with the exterior of the kettle. One of the aforesaid cocks or taps serves
to admit the heated water from the kettle to the cylinder to completely fill it which is
indicated by the escape of water from the waste pipe and the other cock or tap serves
for the passage of the water in the cylinder to the exterior of the kettle and thus to the
article to be tested.
It will readily be seen that the different samples of tea or coffee or other article
receive exactly the same predetermined amount of water, the capacity of the cylinder
heing varied according to the amount of water desired for testing.
In the accompanying two sheets of drawings.
Fig. 1 is a front elevation of a kettle fitted with apparatus constructed according to
my invention, the bandle for the same not being shown; and
Fig. 2 is a sectional plan, and
Fig. 3 a sectional end elevation of the same; and
Figs. 4 and 5 are similar views to fig. 3 showing modifications of the arrangement.
The kettle a is shown provided with three cylinders beach of the desired capacity
fitted internally. Each cylinder is fitted with an inlet cock c for admitting water
from the kettle to its interior and with an outlet cock d for the passage of the water in
the cylinder to the exterior of the kettle and thus to the article to be tested. Each
cylinder is also fitted with a pipe e leading from its top to an overflow channel f
fitted on the exterior of the kettle and provided with a waste pipe y. The heated water.
is admitted to each cylinder b by its cock e which is closed as soon as the said cylinder
is full which is indicated by the escape of water from the pipe e into the channelf.
The passages leading from the cylinders 6 to the cocks enter the said cylinders at
their lowest parts and are preferably slightly inclined as shown so that they shall be
completely drained when the outlet cocks are opened. The pipes e are also inclined as
shown for the same purpose. The inlet cocks c are operated by means of spindles h

page_text: passing up through the water in the kettle and through bushes i in the top of the kettle
and provided at the exterior of the kettle with handles l. The outlet cocks d are also
provided with handles in by means of which they are operated. The capacity of the
three cylinders may be made exactly equal by screwing the cocks d more or less on the
pipes j.
In the modification shown in fig. 4 the outlet cocks d are fitted inside instead of
outside the kettle and are operated in a similar manner to the inlet cocks c by the
spindles n and handles o.
In the modification shown in fig. 5 the inlet and outlet cocks of each cylinder bare
replaced by a single three-way cock p shown fitted inside the kettle and operated by
means of the spindle 9 and handle. The three passages of the cock p communicate
respectively with the interior of the cylinder b, with the water in the kettle and with
the exit pipe s. By means of the plug of the cock p, the cylinder b can thus be put
in communication with either the water in the kettle or the exit pipe s.
It will be obvious that the apparatus may be modified in various ways without
departing from the nature of my invention; for example the cylinders 6 may be
arranged exteriorly to the kettle but this is evidently not so advantageous in cases
where the water is required at the boiling point; and only one or any other suitable
number of cylinders may be fitted to each kettle.
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 construction and arrangement of apparatus for admitting exact quantities
of heated or boiling water to tea or coffee or other article to be tested consisting
of a vessel of the desired capacity fitted to an apparatus for heating water and provided
with means for exactly filling and for completely emptying the said vessel substantially
as described.
2. The construction of apparatus for measuring exact quantities of heated or boiling
water for tea and coffee testing and other similar purposes substantially as described
with reference to figs. 1, 2 and 3; or to fig. 4; or to fig. 5 of the drawings.
