and other Impurities from Chaff.
We, THOMAS HOADLEY, Engineer, and JAMES HOADLEY, Corn Merchant, both of
64, Westbourne Park Villas, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
The object of our invention is to separate dust and other impurities from chaff with
greater facility, and in a simpler and better manner than heretofore.
According to our invention we employ an endless band of perforated material, say
of course canvas, woven or made with a mesh of the required size. This endless band
is stretched over rollers at each end, one of which receives motion by strap from any
suitable motor.
The rollers are mounted in a frame which may be horizontal or at any desired angle,
which frame also forms the bearings for revolving beaters over which the perforated
material, as before described, passes; and in such manner that as the perforated
material travels over the beaters the latter impart to the same a gentle but shaking
motion whereby the dust falls with facility through the bands, while the chaff is
carried away to the end of the band, and falls in a perfectly clean state into a suitable
receptacle there provided for the purpose. The beaters are driven by pulleys on their
axes connected with the main roller or by chain or band in any convenient manner.

page_text: A New or Improved Machine for Removing or Separating Dust
and other Impurities from-Chaff.
We THOMAS HOADLEY, Engineer, and JAMES HOADLEY, Corn Merchant, both of
64 Westbourne Park. Villas in the County of Middlesex 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 :-
The object of our invention is to separate dust and other impurities from chaff with
greater facility and in a simpler and better manner than heretofore.
It is well known that on growing pasture, dust carried by the air adheres, and for
other reasons too numerous to mention sometimes much dirt and dust becomes mixed
with the fodder. This fodder such as hay or clover when cut and dried and afterwards
divided by a chaff cutter, the dust thereon becomes separated, and mixed with
the chaff which when given to horses for example often causes broken wind, in fact
when chaff is put into a horse's manger, the first thing he generally does is to shake it,
the chaff, about, which allows the dust to settle in the bottom of the manger, and
frequently on account of the presence of the dust lie will refuse to eat some of the
food so that the proper sifting of the cut chaff is of great importance. This has been
heretofore done by shaking-sieves, or sieves having a reciprocating motion imparted
to them, but these have not been successful as they cannot be prevented from choking
the chaff sticking into the meshes of the sieves, and the dust lying thereon and
rendering the apparatus useless until cleared.
According to our invention we employ an endless band of perforated material, say
of coarse canvas, woven or made with a mesh of the required size. This endless band
is stretched over rollers one of which receives motion by strap from any suitable
motor. The rollers are mounted in a frame which may be horizontal or at any desired
angle, which frame also forms the bearings for revolving beaters over which the
perforated material, as before described, passes, and in such manner that as the
perforated material travels over the beaters the latter impart to the same a gentle but
shaking motion whereby the dust falls with facility through the bands, while the chaff
is carried away to the end of the band and falls in a perfectly clean state into a suitable
receptacle there provided for the purpose. The beaters are driven by pulleys on their
axes connected with the main roller or by chain or band in any convenient manner.
Figure 1 is a sectional elevation of a chaff cleaning machine constructed according
to my invention and shewn fitted below an ordinary chaff cutting machine.
Figure 2 is a longitudinal vertical section of a chaff cleaning machine of a similar
construction to that shown at Figure 1 but which may be used separately from the
chaff cutter and may also be operated by hand. This figure is drawn to a larger
scale than the apparatus shewn at Figure 1.
Figure 3 is a plan, with the top cover removed, of the same machine, and Figure 4
are detached views of a portion of one of the beaters.
Similar letters of reference refer to like paris in all the figures.

page_text: A is the enless band of perforated material and the material we have found in
practice to answer the purpose well is coarse canvas woven with a mesh of the required
size, which when applied to broad or wide machines should be bound on the edges
with leather or other suitable or equivalent material to prevent the band from creasing
or stretching during its travel. BB are the rollers at each end of the machine round
which the endless band of perforated material A is passed. These rollers BB work
in bearings in the side fraines of the machine, these bearings may be formed in the
woodwork of the frame itself or they may be separate brass or other bearings if desired
although we have found wood bearings to answer the purpose well.
DDDDDDD are the beaters or beater rollers, seven of these beaters are shewn
but a greater or less number may be used according to the size of the machine and the
work it has to do. A beater D may be substituted at each end of the machine for the
roller B.
These beater rollers also work in bearings in the side frames of the machine and are
driven by bevil gearing EE one bevil wheel being on the roller ends and the other on
the shaft F running from end to end of the machine to which shaft F motion is
communicated by pulley G; round this pulley G a band H passes to another and
larger pulley L which latter referring more particularly to Figures 2 and 3 is driven
by hand for which purpose a handle L' is used as shewn. C, C are the bearings for
the horizontal shaft F. The beaters D are composed of bars preferably rounded off at
their edges so as not to injuriously affect the endless band A travelling over or round
same and against which band the beaters as hereafter described press or strike; K is
the casing or framework of the machine forming a sort of long box in which the
endless band A., rollers B B and beaters D are placed and arranged. M is the feed
hopper for feeding the chaff to be cleaned, into the machine; N is what we may call a
throat for regulating and directing the feed of the chaff from the hopper M to the
machine its main object being to prevent the said chaff from falling too abruptly on to
the endless band A and from choking the passage; the throat N is formed by a bar
stretching across the machine and decreasing the height of the available passage for
the chaff. O is the draught aperture or uptake chimney leading from the casing K
to the atmosphere and through which aperture O the finest dust passes or escapes.
PP Figure 2 are boxes one, P, of which is arranged immediately below the uptake O
to receive the chaff travelling along with the dust. This chaff box P is in Figure 1
dispensed with, such particles of chaff as are carried through the machine fall through
the flooring on to the main body of the cut and cleaned chaff below, the other P¹ Figure 2
is for the dust alone, and this is replaced by a sack P' in Figure 1, as shewn.
Pis
a perforated metal cover to the box P¹ which may be fixed in any convenient manner
by sliding in or otherwise. The object of this cover is to prevent any pieces of chaff
that may come through the endless band from falling into the dust box, or sack P¹.
The chaff so falling through the band being carried on to the box P Figure 2, or
through the aperture P Figure 1 from which it is removed from time to time.
Q, Figure 2 is a receptacle for the cleaned chaff. R is a guard band which may be
made of some stout woven material and placed along and fixed to the side of the
framework K so that one edge thereof overlies the running endless band A and
prevents the chaff falling between the end of the said band A and the framework. S is
the top covering having apertures therein for the inlet of chaff at M and the outlet or
uptake of dust at O. T is the bottom covering, space being left for the exit of the
chaff above the receptacle Q Figure 2 and above the receptacle or aperture P, and
space is also left for the perforated plate P².
The beater roller D is made with two metal discs Done at each end of the beater
shaft D. The bars which are generally inade of wood are reduced at their ends and
fit into apertures provided for them in the disc D' as shewn at Figures 4.
The action of the machine is as follows:
The chaff which is fed into the machine at M. falls on to the endless band A which
is kept in motion in the direction of the arrows Figure 3 through the revolution of the
pulleys L G and the shaft F and gearings E. As these beaters D rapidly rotate
the band A has communicated to it a vertically rising and falling motion so that as

page_text: the chaff is carried along on the band the dust and dirt therein are shaken through the
canvas or other band downwards in the direction of the arrows Figure 2 and falls on
the platform or passage and is carried back through same by the draught of air into
the uptake O, some of the dust falling into the box or sack P¹, the greater part of the
finer dust however being carried up the uptake O, being prevented from returning
through the entrance, by the incoming chaff, the clean claff or chaff cleared of dust
falls into the receiver Q Figure 2, or through the aperture Q Figure 1.
Machines constructed according to our invention may be fitted in any convenient
position, and the chaff to be cleaned can be conveyed to the feed by a tube if necessary
from any convenient required place or position.
The machine may, as shewn at Figure 1 be fitted directly under an ordinary chaff
cutter.
The machine is very easily worked, cannot get out of order with fair use, and is not
expensive, points of great importance in machines of this nature.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
First In chaff cleaning or clearing machines, the employment of a travelling
endless band to which a gentle vertical shaking motion is imparted substantially as
and for the purposes set forth.
:
Second: In chaff cleaning or clearing machines, the employment of an endless
band to which a gentle and vertical shaking motion is imparted by means of beaters D,
to which latter, rotary motion is imparted substantially as and for the purposes set
forth.
:
Third In chaff cleaning or clearing machines, the particular construction and
arrangement of beaters D substantially as and for the purposes set forth.
Fourth The general construction and arrangement of machines for cleaning or
clearing chaff substantially composed of an endless band A, beaters D, uptake O,
entrance M, framework and driving gear, all substantially as and for the purposes
herein before described, and illustrated with reference to the accompanying drawings,
together with any mere modification or modifications thereof.
