I FREDERICK WARNER JONES of 30 Great St. Helens in the City of London,
in the County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved pot for making Coffee or similar beverages,
and it has for its object, obtaining a more perfect extract from the ground berries.
To this end my improved pot is constructed as follows :-
:-
Within a pot of any suitable and convenient shape and size is fitted an inner vessel
in the form of an inverted truncated cone, open at the bottom. This inner vessel is
preferably made as part of the outer vessel or pot, and it is provided with a loose
..hitting lid. The outer vessel or pot fitted with a spout which starts from near the
bottom of the vessel; and runs up to about the top of the vessel before it curves to
form the orifice. The top of the spout is connected with the top of the outer vessel
by a small tube pipe or passage, and the spout is provided with a tap cock or its
equivalent in such a position that the orifice of the spout can be opened or closed
to the outer vessel.
:
-
The pot is used in the following manner :-The ground coffee is placed in a small
receptacle which fits in the lower part of the truncated cone-shaped inner vessel, the
pot being partially filled with water. The tap or cock in the spout having been
opened, the pot is boiled by being placed over a lamp or otherwise. When the water
boils, the tap or cock is closed, and the pot is still allowed to boil for a short time,
when by the compression of the steam in the top part of the outer vessel, the water is
forced through the ground coffee into the inner vessel. The tap or cock is then
opened which causes the liquid coffee to again pass through the ground coffee from
the inner vessel to the outer one, whence it is ready for pouring.

page_text: I, FREDERICK WARNER JONES of 30 Great St. Helens in the city of London
in the county of Middlesex, Engineer, 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 an improved pot for making coffee and similar beverages,
and it has for its object obtaining a more perfect extract from the ground berries.
To this end my improved pot is constructed as follows:-Within a pot of any suitable
and convenient shape is fitted an inner vessel in the form of an inverted truncated
cone, or its equivalent, open at the bottom, thus dividing the interior of the pot into
two parts, an outer and an inner part.
The outer part of the pot is provided with a spout of any convenient form or
shape.
The spout is provided with a small tap, plug, or its equivalent in any suitable
position, so that the orifice of the spout may be opened or closed.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing which shows a view in
broken sectional elevation of my improved pot.
In the interior of the pot A, which may be made of any suitable size or shape, is
fitted an inner vessel B preferably shaped as illustrated. This vessel B divides the
pot A into two parts, viz., the outer part A' and the inner part A'. The outer part A¹
is provided with a spout a' of any suitable form or shape.
The orifice of the spout is provided with a plug a³, or its equivalent, whereby the
orifice of the said spout can be conveniently closed.
The pot A is also provided with a suitable handle a and lid a*.
If desired a small receptacle A* may be adapted to fit in the top of the pot A the
lid a being removed and used as a lid for the receptacle A³. This receptacle' A* is
used for heating the milk for use with the coffee.
In the lower part of the vessel B is fitted one or more strainers b, of the shape
illustrated, or any other convenient shape.
This pot is used in the following manner :-The outer part of the pot having been
filled with water-preferably boiling-the ground coffee is placed in the inner vessel
on the strainer b. The orifice of the spout having been closed, the water is boiled
up by placing the pot over a fire or lamp, which causes the liquid coffee to pass into
the inner part A of the pot, through the ground coffee. The pot is then removed
from the fire or lamp when the vacuum in the outer part of the pot causes the liquid
to pass through the ground coffee again into the outer part of the pot, when it is
ready for use; the orifice of the spout being opened to pour out the coffee.
