COMPLETE SPECIFICATION.
A Funnel for Preparing Coffee.
I CARL HOEDER of Alterwall No. 46, Hamburg in the Empire of Germany,
Merchant 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 :-
The object of this coffee funnel is to prepare coffee by shutting off the water so as to
prevent all loss of the fragrancy of the coffee and at the same time to effect an equal
distribution of the water over the coffee by an indirect infusion of the former. The
invention is represented in the accompanying drawing. Fig. 1 is a side view of the
funnel in section. Fig. 2 is a plan view of the funnel the left hand half of which is
represented in section on line x. x. Figs. 3 and 4 are detail drawings of separate
parts of the funnel.
A is the outer mantle of the funnel which is provided at its lower part with a
flange m in order to enable it to be placed upon a suitable coffee pot D or a vessel
for receiving the prepared coffee. Into the inner part of the funnel is placed, upon
a wedge i or otherwise supported, a tube B which is open at the top and closed at
the bottom and which is connected at its lower end with a strainer H. After this
tube and strainer is inserted the ground coffee is placed around B upon said strainer,
then another strainer P provided with a central opening is placed over the tube B.
This strainer P rests upon the flange o of the mantle A and covers the coffee.
Upon the upper edge of the mantle A is now placed the part shown by Fig. 3.
This part consists of an infusion vessels with an edge t to rest upon the mantle A and
a short tuber which is inserted into the broader tube B.
If hot water is poured upon e the same fills at first the tuber and the tube B and
then flows over the upper edge of B in the direction of the arrows and spreads over
the sieve plate P through the openings of which the water then reaches the coffee
and macerates the same, which travels then through the strainer H into the receiving
vessel D.
Upon examination of Fig. 1 the following is the result:
An escape of the fragrancy is impossible during the preparation of the coffee as the
water in the tube B prevents all passage of air or gas through r and e.
The closing
of t at the edge of the mantle A as well as the edge of the coffee pot D can
be constructed sufficiently tight without difficulty to prevent an escape of the
fragrancy.
It can be seen at the same time that an indirect pouring over of the water takes
place by the overflow of the water at B in consequence of which the same reaches
the coffee all over and without a sudden flow.
The mantle A is suitably provided with an outer handle g. At the lower part of
the mantle at va filter made of cloth or paper can be inserted to clear the coffee by
filtering before it enters the coffee pot.
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.
A funnel for preparing coffee consisting of an inserted piece composed of the
tube B with strainer H and of the upper mantle A with inlet e and short tube r
extending into B as soon as t is placed upon the mantle A and over the strainer to
be placed over B.
