Improvements in the Construction of Coffee Pots.
I, Countess IDA SEILEEN ASPANG, of Munich, in the Empire of Germany, do
hereby declare the nature of my said invention to be as follows:-
The object of my invention is to manufacture an improved form and description of
coffee pot, with a lamp attached thereto and forming part thereof.
In carrying out my invention, I place the receptacle for the prepared coffee under
the lamp, and the receptacle for hot water above the lamp. The lower vessel has
double sides, or is formed of two cylinders; the inner one containing the prepared
coffee, and the space between the cylinders being filled with hot water to prevent the
coffee from cooling too quickly.
The lower vessel is fitted with a movable cover, to the inside of which the receptacle
for the ground coffee is attached consisting of two perforated strainers with cylindrical
sides, the lower strainer being movable.
The upper side of the lid of the lower vessel is formed to receive the lamp, which
rests upon the same, when in operation.
The lid also sustains the upper (water) vessel, by means of tubular pillars, one
pillar being fitted with a stop cock and spout, whereby hot water can be poured into
the annular space or jacket of the lower vessel, and one of the other tubular pillars
being fitted with a stop cock and spout whereby hot water can be poured on to the
upper perforated strainer.
The upper (water) vessel is fitted with an ordinary lid, and the lower vessel is fitted
with a tap to draw out the prepared coffee.

page_text: In using this improved coffee pot, the lid of the lower vessel is removed, and
inverted the inner receptacle for ground coffee is then opened, and the coffee
inserted; the lid is then replaced with the ground coffee secured under the same.
The upper vessel is then filled with water; the lamp placed in position and lighted.
When the water boils, some hot water is let into the water jacket of the lower vessel,
to warm the same. The water is then let into the space over the upper strainer.
through which it runs to the ground coffee to the lower strainer, and thence to the
receptacle for the prepared coffee, ready for consumption.

page_text: 1, Countess IDA SEILERN ASPANG, of Munich, in the Empire of Germany, do
hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to manufacture an improved form and description of
coffee pot, and lamp.
In carrying out my invention, I place the lamp upon the receptacle for the prepared
coffee, and the receptacle for hot water above the lamp. The lower vessel has a hot
water jacket, to prevent the prepared coffee from cooling too quickly. The lower
vessel is fitted with a movable cover, to which the receptacle for the ground coffee is
attached, consisting of two perforated strainers, with cylindrical sides, the lower
strainer being movable.
The upper part of the lid of the lower vessel is recessed to receive the lamp, which
rests upon the same, when in operation. The lid also sustains the upper (water) vessel,
by means of tubular pipes, one pipe being fitted with a stop cock and nozzle, from
which hot water can be poured into the jacket of the lower vessel.
The other pipe is also fitted with a stop cock from which hot water can be poured
upon the upper perforated strainer.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing, being a sectional elevation
my invention.
of
a is the receptacle for boiling water, fitted with an overflow pipe h', leading to the
pipe h, below the cock g. The hot water vessel a is sustained in position by the two
pipes and m, fixed to the lid b¹ of the lower vessel b. The pipe has a stop cock 9.
on opening which water can be let into the distributor g¹; and the pipe m has a
stop cock on opening which water can be let into the jacket n, through the
nozzle o.
The upper vessel a has a lid a¹, so formed as to admit the milk warmer 1. The
lid 6' is recessed (as shewn) to receive the lamp c.
The underside of the same lid b¹
is fitted with the cylinder d, to which the rim d' is soldered to govern the position of
the movable perforated plate i. This plate receives the hot water from g¹ and
distributes it upon the ground coffee in the chamber d². e is a short cylinder, the
bottom of which is perforated with small holes, in which cylinder the ground coffee is
placed. k is a tap for drawing off the coffee.
When using my invention the lower vessel and the lamp are removed; the upper
part is then inverted; the inner receptacle for ground coffee is opened, and the coffee
inserted; the cylinder d² is replaced enclosing the ground coffee. The lid with the
vessel a attached is then placed upon the vessel b. The upper vessel is then filled with
water and covered up, as shewn; and the lamp placed in position and lighted. When
the water boils, some hot water is let into the water jacket n of the lower vessel, to

page_text: warm the same. Hot water is then let into the space over the distributing plate i,
through which it runs to the ground coffee placed upon the lower strainer, from whence
the infusion percolates to the space b ready for consumption.
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 manufacture and use of coffee pots, having the vessel a, for boiling water,
placed above the jacketted vessel for the prepared coffee, with the heating lamp c
between the two vessels, the cover or lid of the coffee vessel sustaining the lamp and
the receptacle for ground coffee, substantially as herein before described and shewn on
the drawing.
2. The general construction arrangement and combination of the several and respective
parts, together forming my invention of improvements in the construction of coffee
pots, substantially as herein before described and shewn on the drawing.
