PROVISIONAL SPECIFICATION.
Improvements in and Apparatus for Dividing or Comminuting Coffee,
Spice, Cereals, or the like.
I, SALOMON FRANK, of 4, Blücherplatz, Frankfort-on-the-Main, in the German
Empire Engineer, do hereby declare the nature of this invention to be ag
follows:-
The object of this invention is to provide simple and efficient means for dividing
or comminuting coffee, spice, cereals, or the like.
According to this invention the material to be acted upon is fed into a cylinder
open at one end and provided with a small perforation, or small perforations, at
the other end. A piston, accurately fits the said cylinder so that when it, is
forced into the cylinder the substance issues from the said perforation or perfora-
tions in thread-like form which readily crumbles to dust.
If preferred, the perforations may be formed in the piston instead of, or as well
as, in the cylinder, when the threads of material will issue from the piston,
instead of, or as well as, from the cylinder.
By the aforesaid means a very finely divided product can be obtained in a very
short time.
The apparatus for carrying out the operation may conveniently consist of a block
having formed in it a cylindrical recess from which opens a small orifice the top
of which is preferably funnel-shape. Into the said cylindrical recess a piston is
fitted so that when the piston is pressed in the material issues in thread like form
from the orifice.

I, SALOMON FRANK, of 4, Blücherplatz, Frankfort-on-the-Main, in the German
Empire, 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:-
The object of this invention is to provide simple and efficient means for dividing
or comminuting coffee, spice, cereals, or the like.
According to this invention the material to be acted upon is fed into a cylinder

the other end, A piston, accurately fits the said cylinder so that when it is
forced into the cylinder the substance issues from the said perforation or perfora-
tions in thread-like form which readily crumbles to dust.
If preferred, the perforations may be formed in the piston instead of, or as well
as, in the cylinder, when the threads of material will issue from the piston,
instead of, or as well as, from the cylinder.
By the aforesaid means a very finely divided product can be obtained in a very
short time.
Figures 1 and 2 of the accompanying drawings illustrate, as an example, a
suitable apparatus for conveniently carrying out the operation and consists of a
block a having formed in it a cylindrical recess or passage b, the lower end of
which is conical and terminates in a small orifice c. In this cylindrical recess b
a piston is fitted so that when the piston is pressed inwards the material which
is placed in the said recess beneath the piston is forced out through the orifice c
in thread-like form e as shewn in Figure 2 which can be readily comminuted or
crushed for use.
Instead of providing the orifice in the bottom of the recess, as shewn in
Figures 1 and 2 the recess may be closed at the bottom as shewn in Figures 3
and 4 and a small passage e be made through the piston so that when the
piston is pressed onto the material placed in the recess b the said material will
be caused to pass through the passage in the piston in thread-like form as shewn
in Figure 4.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:
For dividing or comminuting coffee, spice, cereals, or the like, a chamber or
recess in which the material to be divided or comminuted is placed, a piston fitted
accurately to slide in the chamber or recess and a perforation or perforations pro-
vided in the bottom of the chamber or recess, or in the piston, or in both, through
which perforation or perforations the material is, by the pressure of the piston,
caused to pass in thread-like form, substantially as hereinbefore described.
Dated, this 21st day of October 1899.
