or Grain...
CHARLES EDWARD MUMFORD St. Andrews Works Bury St. Edmunds Engineer
DAVID HEARN 6 St. Andrews Street North, Bury St. Edmunds Engineer do hereby
declare the nature of this invention to be as follows:-
This invention relates to machines for cleaning Malt from chives, dust, &c. ; & for u
polishing the same & for husking or polishing other Grain, & may be used alone, or
if desired in conjunction with screens, or other Machines or Malt. Rolls of known....
construction.
According to our invention, the malt or other Grain or Seeds to be cleaned is fed
from a suitable Hopper fitted with a " stirrer" into a series of three or more circular__
brushes placed in a horizontal position & working parallel to each other. The second,
hird, or following brushes being slightly lower than the one, placed just beneath the
Hopper, motion being enparted to them by gears or chains. These brushes are
onclosed in and worked in adjusting concaves, part of which are open or grill work
o connect the escape of chive & part of which are solid for the purposes of friction
part of which are of fine open work to permit the escape of dust, which is removed
by..means of an exhaust fan, in connection with a chamber former over the said part
f.concaves. The Hopper is provided with a slide for regulating the feed, and the
ast, or outlet brush is fitted with an adjusting outlet slide for the purpose of checking
regulating the escape of the Malt or other Grain from the apparatus. .
.
The machine is driven either by hand power or in the ordinary manner by a
ulley fitted on the spindle of one of the rollers, or fan.

or Grain.
We, CHARLES EDWARD MUMFORD, St. Andrew's Works, and DAVID HEARN,
6 St. Andrews Street, North, both in Bury St. Edmunds, 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:-
Our invention relates to machinery for cleaning, polishing and taking chives off
malt, for separating the chives and dust therefrom and for husking and polishing and
cleaning rice, coffee or other seeds or grain.
For this purpose the malt or other granular material is fed from a hopper provided
with an agitator to the first of three or more cylindrical brushes revolving on hori-
zontal axes within casings the upper parts of which are close and the lower parts
are of grill work to allow escape of the chives.
From the upper part of the last concave the dust is drawn by an exhaust fan.
The accompanying drawing is a longitudinal section of a machine having three
brushes, suitable for treating malt. A is the feed hopper provided with a revolving
agitator B, and an adjustable sluice C to regulate the feed. D D D are the three
cylindrical brushes which revolve within casings the upper parts of which E¹ E' E'
are close, the lower parts F1 F2 F3 of grill work.
From the upper part of the last casing E' a channel G leads to an exhaust fan H
by which the dust is removed.
The cleaned malt or other material is discharged by a shoot K provided with a
regulating sluice L.
As shown in the drawing the axis of the first brush D₁, which may be driven by
hand or other power, has on it pullies for driving by bands the fan H and the
agitator B, the second and third brushes D2 D3 being driven by gearing from the
first. Any other suitable mechanical connections of the moving parts may, however,
be employed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
:-
For cleaning and polishing malt or other granular material the combination of a
feed hopper, three or more cylindrical brushes revolving in casings having their
lower parts of grill work, a discharge shoot and an exhaust fan, arranged and
operating substantially as described.
