Owner, do hereby declare the nature of this invention to be as follows:-
This invention relates to an apparatus by means of which freshly roasted coffee
may be kept without contact with the air both during the time that it remains in a
whole state and also during the time that it is being ground to prepare it for
immediate use. By this means the aroma and flavour of the roasted coffee is fully
preserved.
The apparatus consists of the receiver for the coffee provided with an outlet and
means for closing the same, the same being put in connection with a grinding
apparatus.
The receiver consists of a vessel preferably of tin or the like with a closed bottom
in which is a circular opening closed by a slide, above this opening is a short length
of tube in which the actual outlet. tube is adapted to slide up and down. This outlet
tube extends upwards through the whole length of the vessel and passes through the
lid of the latter through a rubber ring so that it may be moved up and down without
letting air pass into the vessel. The lid is fastened on the vessel by means of a
bayonet fastening. The upper end of the tube is closed by a suitable stopper and the
lower end of the tube has 2 lateral openings. A helical spring of sufficient strength
rests at one end on the bottom of the vessel and carries at its upper end a false
bottom. This false bottom is connected in any suitable manner with an indicator by
means of which the position of the false bottom may be shown from a scale.
The whole of the above apparatus rests in a suitable frame which may be fastened
to a wall or otherwise supported over the grinder. It is preferable that the above
apparatus should be easily removable from the grinder so that if necessary it may be
used with any other ordinary coffee mill.
The action of the apparatus is as follows:-
When the coffee vessel is empty the false bottom is raised by the spring and the
indicator pointing to zero shows that the vessel is empty.
When coffee is placed in it the movable bottom would sink under the weight of the
coffee more or less, according to the amount put into the vessel, which amount will
be therefore indirectly shown by means of the indicator. When the lid is closed the
coffee will remain protected from the outer air.
In order to obtain a desired amount of coffee, the slide is first opened and the out-
let tube is lifted until a collar on this tube abuts against the lid, the coffee beans
fall through the lateral openings in the outlet tube and thus pass into the short
length of tube which surrounds and serves as a continuation between the outlet tube
and the opening in the fixed bottom of the vessel. The coffee beans thus fall into
the grinder. As the coffee continues to fall the pressure of the coffee that remains
will be gradually diminished on the false bottom so that the latter will rise for a
corresponding amount under the action of its supporting spring. When the indicator
shows that a sufficient amount of coffee has thus fallen into the grinder the outlet
tube is pushed down and its lateral openings thus again become closed by the short

page_text: length of tube which surrounds its latter end. The slide closing the opening in the
bottom of the vessel may now be closed. The coffee is then ground in the mill and
can be taken direct therefrom for subsequent use.

I, JOSEF ANTON KLEITER, of Bäckerstrasse A 342/44, Augsburg, in the Empire of
Germany, Mill Owrer, 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 :—
This invention relates to an apparatus by means of which freshly roasted coffee
may be kept without contact with the air both during the time that it remains in a
whole state and also during the time that it is being ground to prepare. it for
immediate use. By this means the aroma and flavour of the roasted coffee are fully
preserved.
In the annexed drawing the apparatus is represented in two forms of construction.
The apparatus represented in Fig. 1 is longitudinal section consists of two principal.
parts, 1, the receiver for the coffee provided with an outlet and means for closing the
saine; and 2 the grinding apparatus.
The receiver consists of the vessel a, which is made either entirely or partially of
some transparent material, such as glass, funnel-shaped at the bottom and open at
top and bottom. The vessel a is placed upon the case q which contains the grinding
apparatus and is open at the top. The purpose of the vessel a is to receive coffee
and the said vessel is closed at the top by means of lid g, which may be fastened on
the vessel by means of a bayonet fastening if desired. In a hole in the lid g the
tube slides; the latter is provided at the top with a knob or handle forming a
stopper and serves on the one part to close the lower, narrow opening y of the
vessel and on the other part for filling purposes. For the latter purpose the tube f
is provided with two lateral openings which in the closed position, are below the
upper edge of the opening y. When it is desired that coffee should pass from the
receiver a to the grinding apparatus, the stopper k, and thereby the tube is lifted
until the openings i are above the lower orifice y of the receiver a and thus admit
the coffee from the receiver to the grinding apparatus g.
When sufficient coffee has
passed through which can be easily ascertained owing to the transparency of the
receiver a, the tube is moved downwards again until it closes the orifice y. The
filling of the apparatus either takes place through the hole in the lid g after
removing the stopper or else the lid j is removed for the purpose.
Another form of construction is represented in Figs. and 3.
In this case the receiver consists of a vessel with a closed bottom in which is
a circular opening e closed by a slide d.
Above this opening is a short length of tube o in which the actual outlet tube f
is adapted to slide up and down: This outlet tube f extends upwards through the
whole length of the vessel and passes through the lid g of the latter through a rubber
ring so that it may be moved up and down without letting air pass into the
vessel. A lielical spring of sufficient strength rests at one end on the bottom of
the vessel a and carries at its upper end a false bottom m. The latter slides with
as little friction as possible in the vessel d. The false bottom m is connected by the
lever device in with the indicator o by means of which the position of the false
bottom may be shown from a scale.

page_text: The receiver a rests in a frame p which may be fastened to a wall or otherwise
suitably supported over the grinder 7. It is preferable that the above apparatus
should be easily removable from the grinder q, so that if necessary it may be used
with any other ordinary coffee mill.
The action of the apparatus is as follows:
When the receiver a is empty the false bottom massumes the position indicated
in Figure 2 by solid lines and the indicator points to zero.
When the coffee is placed in the receiver a the false bottom in sinks under the
weight of the coffee into the position indicated in Fig. 2 by dotted lines and the
indicator is moved by the lever device n. The lid g is then fastened on to
the vessel a and the coffee is thus protected from contact with air.
In order to obtain a desired amount of coffee the slide d is first opened and the
outlet tube is lifted until the openings i are outside the tube e. A collar or
abutment will facilitate this. The coffee beans thus pass through the openings i
into the tube e and through the opening in the bottom into the grinding
apparatus q. As the coffee continues to fall the pressure of the coffee that remains
will be gradually diminished on the false botton m so that the latter will rise for
a corresponding amount under the action of the spring. The movement of the
false botton m will be transmitted by the lever device n to the indicator o so that
the quantity of coffee removed will be shown from the scale. When the desired
quantity has been obtained from the receiver a the outlet tube f is pushed down until
its lateral openings i are within the tubere and no more coffee beans can pass through.
The slide may then be closed. The coffee is then ground in the mill and can
be taken direct therefroin for subsequent use.
The first of the two forms of construction described is preferable for small
apparatus, the second for large apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. An improved receptacle for roasted coffee provided with a receiving vessel (a)
for the coffee, funnel-shaped at the bottom and arranged above the grinding
apparatus, the outlet (y) of the said receiving vessel being opened or closed by
means of a tube provided with lateral openings () and adapted to be slid up -
and down as described.
2. The form of construction of the apparatus described in Clain I in which
anovable bottom m is arranged above the closed bottom of the receiving vessel (a)
and the position of the said movable bottom (m) is dependent upon the pressure
of the coffee above it and the movements of the said movable bottom (m) are
transmitted to an indicator o by means of a lever device n.
