1, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester,
both in the County of Lancaster, and 323, High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machines and apparatus for cleaning malt, separating the
kernel from the sprouts, and removing all dust, grit, stones and other foreign sub-
stances; and the object is to increase both the utility of the machine and its capacity
and durability.
It consists in the several novel features of construction and combination of parts.
hereinafter described.
It is constructed as follows:-
A is the main frame of the machine constructed with horizontal and vertical
timbers upon the sides and ends; and upon this frame is mounted the fan box 1, the
fan, 2, being journaled near the rear end of the machine, and upon the outer end of
the fan arbor is mounted the drive pulley 3, and just within it upon the same arbor, a
smaller pulley, 4, from which the belt 5, transmits the power to the pulley 6, mounted
upon the axis of the roll 7, and upon the same axis and within the pulley 6 the
pinion 8 is secured and 9, 10, 11, 12, and 13 are other pinions meshing with the
pinion 8, and with each other substantially as shown in Figure 1, so that each pinion
rotates in the direction indicated by its arrow.
The pinion 9 is mounted upon the axis of the roll 14; the pinion 10 upon that of
the roll 15; the pinion 11 upon that of the roll 16; the pinion 12 upon that of the
roll 17 and the pinion 13 upon that of the brush 18; and the axes and all of these
several rolls are journaled in the sides of the hopper 19, the rolls being transverse
thereto, and 20 is the feed spout.
The brush roll is an ordinary still brush roll; and the other rolls are of wood
and are spirally corrugated or fluted substantially as shown in Figure 6.
These wooden rolls are arranged so that they do not quite touch each other, and
also so that the spirals run opposite to each other.
The bottom of the hopper is inclined and this inclined bottom as also the back, is
covered with the corrugated and perforated lining 21, which extends down to the
hopper discharge 22, and 23 is a spring valve plate closing the mouth of the discharge,
except as it is thrown away by the hand screw so that the discharge of the grain
from the hopper can be regulated thereby.
The perforation in the linings, 21, permit the dust to escape from the grain,
and the corrugated surface somewhat retards the down floor toward the discharge.
The actual discharge is the amount which finally passes through under the brush
roll, 18, when the grain leaves the hopper it enters the vertical passage way, 24,
encountering, and passing down through an upward current of the air which
removes all of the free dust, and the grain falls on to the sieve 25, which is of
sufficiently large mesh to permit the kernels to pass through on to the sieve or
board 26, while the stone, nails and other foreign substances, too large for the
:

page_text: mesh, remain upon the sieve, and work down and off from the sieve and are caught
in the inclined trough 27.
From the board 26, the grain drops on to the sieve 28, through which the grain
drops on to the sieve 29, the impurities remaining upon the sieve 28, working down
into the trough 30, where they are caught and carried away.
In like manner the grain passes through the sieve 29, on to either the cockle
sieve, 31, or sieve, 32, the impurities of the sieve 29, working off into the trough 33,
and those upon the sieve 31, into the trough 34.
The sieve 32, is of fine mesh retaining the kernels, the dust and fine impurities
passing through it into the bottom 35, whence they are removed in any ordinary
manner, while the grain passes down over the sieve falling into the passage, 36, and
down through a counter current of air sucked through this passage into the fan, such
suction being adjustable by means of the valve 37, and the grain discharges into a
proper receptacle.
These several sieves and spouts are mounted in a swinging frame, vibrating like the
sieves of a fanning mill, and are so vibrated by the following mechanism.
Upon the end of the fan shaft opposite to that upon which the draught pulley, 3,
is mounted another pulley 38 is mounted, which is connected to the pulley 39, upon
the horizontal shaft 40, mounted in boxes 41 upon the upright frame timbers, sub-
stantially as shown, and upon each end of this shaft, is secured an eccentric holder 42
consisting of a flat circular disk provided with diametrical slots, 43; and 44 is an
eccentric adjustably secured thereto by bolts passing through the slots substantially
as shown.
The throw of these eccentrics creates the vibration of the sieve, and the extent of
such vibration is varied by increasing or decreasing such throw by shifting the bolts
in the slot.
Each eccentric is provided with a short shaft which is journaled in a box, 45, which
is secured to the side of the sieve frame.
Also each eccentric is provided with an armı 46, on top of which is secured a flat
spring 47, the other end of which is connected to the side of the sieve box;
48 and 49 are the vertical springs, one end of which are secured to the bed timbers
of the main frame and the other ends are socured to the side of the sieve frame,
one spring at each end. A small part of the sprouts rubbed off from the malt, by
the rolls and brush and also such particles of impurities, husks, and dust, as can be
carried by the air current, are taken from the outlet, 23, up through the passage 24,
into and through the one or the other of the chambers 50, into the fan, which
blows them out into a dust room where the sprouts settle, and the impurities are blown
away out of the doors.
It will be observed that the cockle sieve, 31, eliminates all of the sprouts, cockle
mustard seed etc. from the malt.
:
It will be also observed that the rolls are in the first place separated from each other so
that the grain or malt cannot be crushed or broken between them and secondly,
that by means of their being spirally corrugated and separated also the malt is
thrown about this way and that, and all of the time the kernels are rubbing each
other and thirdly from the rotation of the rolls in opposite directions the grain
is retained the longest possible time and exposed to the minimum amount of rubbing
and consequent cleaning, and that none can escape except what is carried out by the
brush.

escape from the hopper except what passes through under, or rather is carried out by
the brush, the bristles of which perform the final brushing and cleaning.
It will be further observed that the grain so cleaned can be discharged on to an
ordinary sieve by which the impurities are removed either with or without air blast.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a malt cleaner, a series of rolls provided with spiral corrugations rotating in,
opposite directions, and a rotating brush in combination with and mounted in
the sides of an enclosing hopper provided with corrugated lining, substantially as
described.
2. In a malt cleaner, the combination of an enclosing casing having corrugated
lining, an inclined perforated bottom and a discharge orifice at the bottom of the
incline, an inclined series of corrugated rolls rotating in opposite directions, and a
brush interposed between the lowest roll and the discharge opening, substantially as
described.
