A Conveying and Abrading Device for Use in Machines for
Degerming, Hulling, and Polishing Grain.
•
I, EMANUEL JGNAZ HELLER, of No. 6-8, Stürzergasse, Iglau, Moravia, Austria,
Millstone Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
For producing a machine for transporting, turning, de-germing, hulling and
polishing grain, in a rational manner, there is employed according to the present
invention, a working implement suitably made of stone or of mouldable material
which is formed in such manner with a helical surface that the implement has
the appearance of a screw spindle. An implement so formed of a screw-like
appearance possesses the peculiarity that according to the greater or less degree
of roughness imparted to its surface, it can transport, turn, as also de-germ,
hull and polish the grain. No tool or implement exists that will fulfil all these
functions at one operation.
It has been attempted to transport and at the same time to act upon grain by
means of one and the same working appliance, but this has only been very imper-
fectly effected, because the working implements were not formed as screw spindles
and did not possess a rough surface, but only had helically arranged discs or pins on
their surface.
The accompanying drawing shews a working implement constructed according
to the present invention, from which it will be seen that the surface can be variously
formed; either the screw spindle-like surface is entirely uniformly rough or it is
formed with several progressive degrees of roughness and is made with projections
of any kind. For producing these projections the surface can be formed at
different points with interruptions or openings as at a a, which have for their
object to form a greater number of edges which effect the more frequent turning
of the grain so that it is more energetically acted upon. It is not necessary that
the working implement shall be made throughout of a homogeneous material;
it can also be formed with a core of suitable material, which is then covered by a
mass suitable for operating in the above described manner, as shewn at bc, b being
a metal blade fixed to the spindle d, while c is a coating of any suitable hard
compound that will produce the abrading action.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A working implement made of hard natural or mouldable material, for
machines for degerming, hulling, and polishing grain, which implement is formed
as a screw spindle and has a more or less rough surface for the purpose of enabling
the grain to be uniformly transported, turned, de-germed, hulled and polished,
substantially as described.
2. In a working implement of the kind referred to in the first claim constructing

page_text: the helical surface with interruptions or openings of suitable form for facilitating
the turning over of the grain to a greater or less degree, substantially as described.
3. A working implement of the kind referred to in the first and second claims,
the screw-like surface of which is made partly with, and partly without pro-
jections, substantially as described.
4. A working implement of the kind referred to in the preceding claims, pro-
gressive portions of whose surface are roughened with an increasing degree of
fineness, in order to enable the same to effectually de-germ, hull and polish every
kind of grain on a single passage thereof through the implement, substantially
as described.
