PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Purpose of Polishing Malt.
1, MATTHEW BYRNE of 42 James's Street Dublin, Ireland, Engineer, and Iron
Founder, do hereby declare the nature of this invention to be as follows :-
This invention has reference to improvements in wheat cleaning machinery whereby
such machinery is rendered available for the purpose of polishing malt in an
economical and effectual manner, and without breaking, or injuring the grain.
In carrying out my invention I deal with that type of wheat cleaning machine
wherein the wheat is cleaned by being allowed to drop through vertical shoots, or
spouts during the passage through which, it comes in contact with a vertically
arranged cylindrical brush which arresting the falling progress of the grain, dashes
it laterally against the meshes of a wire screen surrounding the brush, whereby the
grain is cleaned and separated from "tailings" and other impurities.
Now the machine as thus constructed is not suitable for the purpose of dealing with
mall and my invention is designed to render it available for this object.
To this end I propose to substitute for the cylindrical brush above described, a
conical shaped brush, and also to substitute for the wire screen a cylinder composed of
smooth surfaced steel, or other suitable metal.
These improvements enable the process of polishing malt to be carried on in a
complete and effectual manner.

COMPLETE SPECIFICATION.
Improvements in Machinery for the Purpose of Polishing Malt.
I, MATTHEW BYRNE of 42 James' Street, Dublin, Ireland, Engineer and Iron
Founder 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 has reference to improvements in wheat cleaning machinery whereby
such machinery is rendered available for the purpose of polishing malt in an
economical, and effectual manner and without breaking, or injuring the grain.
In carrying out my invention I deal with that type of wheat cleaning machine,
wherein the wheat is cleaned by being allowed to drop through vertical shoots, or
spouts during the passage through which it comes in contact with a vertically
arranged rotating cylinderical brush which arresting the falling progress of the grain
throws it laterally against the meshes of a wire screen surrounding the brush whereby
the grain is cleaned, and separated from tailings" and other impurities.
Now the machine as thus constructed is not suitable for the purpose of dealing
with malt, and my invention is designed to render it available for this object.
To this end I propose to substitute for the cylinderical brush, above described, a
conical shaped brush, and also to substitute for the wire screen, a cylinder composed
of smooth surfaced steel, or other suitable metal.
These improvements enable the process of polishing malt to be carried on in a
complete, and effectual manner.
The accompanying Drawing will enable my invention to be more clearly under-
stood A, represents the framework of the machine which contains an ordinary fan
in its upper portion, and the usual draught chambers B, incidental to such machines,
[Price 6.1

page_text: C is the conical brush which is of the ordinary construction, and rotates on the
axis D.
The introduction of the screen or cylinder is shown at c, c, consisting of smooth
surfaced steel, or other smooth surfaced metal which surrounds the brush and consti-
tutes the essential feature of my invention.
Around this screen or cylinder is an outer casing forming an annular space through
which the tailings and other impurities of the malt are carried away by the draught,
or current of air produced by the fan operating in the upper part of the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood
that I do not confine myself specifically to the use of a conical shaped brush as the
same may be parallel, or otherwise varied in section as found convenient for
the purpose in view; what I therefore consider as my invention, and desire to
claim is
1st. In machinery of the ordinary wheat cleaning character, the application of a
screen, or cylinder of smooth polished steel or other suitable metal in lieu of the
ordinary wire, or perforated screen whereby I am enabled to utilize such machinery
for the purpose of polishing malt substantially in the manner herein described.
2nd. In machinery for polishing malt the use of a screen or cylinder of smooth
polishe steel, or other suitable metal, in combination with a vertical rotating
brush, arranged, and operating in the manner substantially as herein specified and
set forth.
