PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cleaning and Polishing Malt, Grain,
and the like.
I, CHARLES EDWARD MUMFORD of St. Andrew's Works, Bury St. Edmunds, in
the County of Suffolk, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to apparatus for cleaning and polishing malt, grain and the
like, separating chives, loose husks and other impurities therefrom. For this purpose,
I employ an inclined screen having meshes of such size that the malt or grain dealt
with cannot pass through, but that the detached impurities can find their way through.
At the upper part of this screen I provide a feed hopper, and immediately in front of
it I mount a flat brush which, by means of connecting rods from cranks on a rotating
shaft, is caused to reciprocate, rubbing the surface of the screen. The malt or grain
as it passes from the hopper thus becomes rubbed and brushed and then descends the
screen in a cleaned and polished condition. The crank shaft may also give recipro-
cating motion to a heater or set of beaters which by tapping the screen promotes
the passage of the materials along and through it.
Dated this 26th day of October 1889.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cleaning and Polishing Malt, Grain,
and the like.
1, CHARLES EDWARD MUMFORD St. Andrew's Works, Bury St. Edmunds, in
the County of Suffolk, 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:-
-
My invention relates to apparatus for cleaning and polishing malt, grain and the
like, separating chives, loose husks and other impurities therefrom. For this purpose,
I employ an inclined screen having meshes of such size that the malt or grain
dealt with cannot pass through, but that the detached impurities can find their
way through. At the upper part of this screen I provide a feed hopper and
immediately in front of it I mount a flat brush which by means of connecting rods
from cranks on a rotating shaft is caused to reciprocate, rubbing the surface of the
screen. The malt or grain as it passes from the hopper thus becomes rubbed and
brushed and then descends the screen in a cleaned and polished condition.
Fig. 1 of the accompanying drawings is a vertical longitudinal section, and Fig. 2
is a transverse section on X X of apparatus according to my invention.
A is the hopper, B the transversely reciprocating brush worked from a crank Con
a spindle D which is driven by a band or chain from a pulley or chain wheel E,
worked by hand or from any convenient motor. In order to render the brush B
more effective, the upper part F of the screen is made to reciprocate always in
direction opposite to the brush. For this purpose, the brush B and the part F of the
screen are linked to opposite ends of a rocking lever G as shewn in Fig. 2. The
lower part H of the screen is stationary, also I provide a portion K. of screen behind
the descending feed from the hopper A and fix to the brush B a back board L which
reciprocating with the brush keeps the feeding passage clear and causes a portion of
the light impurities to separate from the descending material and to pass through the
screen K.

page_text: 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 :
Apparatus for cleaning and polishing malt, grain and the like, substantially as
herein described with reference to the accompanying drawings.
