Improvements in Cut Chaff or Fodder and Grain Cleaners and
Separators.
I JOHN DIBBS of Ferrensby House, Waterloo Street Harrogate, Hay Straw
and Corn Merchant do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to reclaim and make fit for cattle food cut chaff
and fodder which is mildewed or musty or which contains dust, dirt or other
impurities; which cut chaff or fodder is at the present time to a great extent
wasted.
In order to accomplish this I employ a machine of special construction into
which the cut chaff or fodder is fed, by means of a hopper funnel or spouting, into
a cylinder or chamber which is divided into two parts by a worm of suitable pitch
which may be faced on its circumference with bristles thus forming a brush if
required. The said worm is keyed or otherwise secured on a shaft running through
the axis of the cylinder or chamber. Bosses are also keyed on the shaft in each
division, carrying arms on which are mounted brushes inclined at an angle to the
axis of the cylinder or chamber in order to give when rotated a traverse or feed to
the material upon which the machine is operating. The circumference of the said
cylinder or chamber is formed of perforated zinc or tin or wire gauze of different
grades or meshes. That forming the circumference of the first division which is
connected with the hopper funnel or spouting being of suitable grade or mesh to
allow only impurities separated from the cut chaff or fodder during the first
brushing to pass through it. That forming the second being of suitable grade or
mesh to pass the partially cleansed cut chaff or fodder; a larger opening at the
end of the cylinder or chamber passes the longer ends out of the machine. Below
the said chamber is a centrifugal blower driven by belt from the worm shaft or
other suitable gearing. Motion is imparted to the machine by swape or pulley
keyed or otherwise secured on the extremity of the worm shaft as hand or power
driving may require.
The action of the machine is as follows:-The cut chaff or fodder is fed into the
first division of the cylinder or chamber where it is partially cleansed by the
revolving brushes, the impurities being driven through the perforated zinc or tin
or wire gauze and carried away by an inclined casing or spouting. It is then
carried by the worm to the second division of the cylinder or chamber where it
receives a second brushing and is driven through the perforated zinc or tin or wire
gauze the longer ends only remaining-which are expelled through the larger
'

page_text: opening at the extremity of the cylinder or chamber to be afterwards returned to
the chaff cutter. The cut chaff or fodder then slides down an inclined casing or
spouting and drops before the air blast from the centrifugal blower, some dropping
from the machine and the remainder being carried on to a perforated recess from
whence it is thrown up by beaters, keyed or otherwise secured on an extension of
the centrifugal blower shaft which allows the air blast from the centrifugal blower
to drive further impurities through a perforated zinc or tin plate or wire gauze behind.
These enter the inclined casing or spouting before referred to and are carried away
with the impurities from the first division of the cylinder or chamber. A baffle
plate is also fixed to divert any return draught downwards, which would carry any
remaining impurities through the perforated recess below. This cleansed cut chaff
or fodder in turn falls from the machine, and is, together with that which fell
direct, now ready for use.
Although the invention is described as applied for cleaning and separating cut
chaff and fodder only it is equally adapted for cleaning grain seeds &c. but in using
it for this purpose 1 employ an additional hopper and spout with which to feed the
grain seeds &c. into the inclined casing or spouting which leads to and drops it
directly over the air blast from the centrifugal blower instead of being brushed in
the cylinder or chamber. A slide in the form of a sluice is also fixed to regulate
the fall of the grain seeds &c. to the bottom of which a reciprocating motion is
imparted by an eccentric on the centrifugal blower shaft to prevent clogging. The
beaters and perforated plate or gauze behind are removed, also the perforated
recess which is replaced by a spout. The heavier grain, seeds &c. can now drop
through the air blast out of the machine-the lighter ones being carried away by
the supplementary spout beyond. The impurities are blown down the inclined
plane or spouting before described for that purpose.

COMPLETE SPECIFICATION (AMENDED).
Improvements in Cut Chaff or Fodder Cleaners and Separators.
I JOHN DIBBS of Ferrensby House, Waterloo Street Harrogate Hay and Corn
Merchant, 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 this invention is to reclaim and make fit for cattle food cut chaff
and fodder which is mildewed or musty, or which contains dust, dirt or other
impurities which render it unfit for cattle food and consequently useless for that
purpose.
In order to fully illustrate my invention I have hereunto annexed 3 sheets of
drawings and the figures of reference thereon, correspond with those in this
Specification.
Fig. 1 shews the machine as used for cleaning eut chaff and fodder with the side
cover board removed, to shew the construction of the cylinder &c. within.
Fig. 2 is an end view of same.
Fig. 3 is a longitudinal section of cylinder shewing brushes and worm.
Fig. 4. is a cross section of same on line a. b.
Referring to Figs. 1. 2. 3 and 4 which illustrate the machine as used for cleaning
cut chaff and fodder, A is a hopper or funnel (or a spout may be used) to feed the
cut chaff or todder which is to be cleansed to the first division or compartment B
of a cylinder or chamber which is divided into two parts by a worm C (of suitable
pitch) which may be faced on its circumference with bristles, thus forming a brush

page_text: if required. D is the second division or compartment of the cylinder or chamber..
The worm C is keyed or otherwise secured to the shaft G running through the axis.
of the cylinder or chamber. Bosses carrying arms on which are mounted brushes H
(inclined at an angle to the axis of the cylinder or chamber in order to give a
traverse or feed to the material operated upon) are also keyed or otherwise secured..
to the shaft G in each division or compartment of the cylinder or chamber. The
circumference of the division or compartment B is formed of perforated zinc or tin
or wire gauze of suitable grade or mesh to allow only the impurities separated
from the cut chaff or fodder whilst in that compartment to pass through it-thit
of D is of suitable grade or mesh to pass the partially cleansed cut chaff or fodder
and retain only the longer ends which pass from the machine by way of the opening
and spout E at the end of the cylinder or chamber. Below the said cylinder or
chamber is a centrifugal blower I driven from shaft G by belt or other suitabl
gearing. Motion is imparted to the machine by swape or pulley keyed or otherwise.
secured on the extremity of the shaft G as hand or power driving may require..
The shaft G is shewn of sufficient length for the driving pulley or swape to be
fixed at either end. The machine can be driven from the chopper pulley if required.
F is an inclined plane down which the cut chaff or fodder is conveyed to the air-
blast. J are the beaters keyed or otherwise secured to the blower shaft. K is a
perforated zinc or tin plate or wire gauze behind and L is a recess with the bottom
formed of the same material. M is the baffle plate and N is an inclined plane or
casing which carries away all the impurities.
The action of the machine is as follows:-The cut chaff or fodder is fed through.
the hopper or funnel A direct from the chopper (or through a spout if preferred).
to the first division or compartment B of the cylinder or chamber, where it is
partially cleansed by the revolving brushes H the impurities being driven through
the perforated zinc or tin or wire gauze forming the circumference and carried
away by inclined plane N. The cut chaff or fodder is then carried by the worm C
to the second division or compartment D of the cylinder or chamber where it.
receives a second brushing and is driven through the perforated zine or tin or wire'
gauze forming the circumference thereof, the longer ends only remaining to be
expelled by way of the aperture and spouting E. The cut chaff or fodder together
with the impurities loosened by the second brushing then falls onto and slides down
the inclined plane F, from whence it drops through the air blast from the
centrifugal blower I, the impurities being blown through the perforated zinc or tin.
plate or wire gauze K behind and recess L below. One portion of the cut chaff or
fodder which is now thoroughly cleansed falls direct from the machine and the
other or lighter portion is carried onto the recess L from whence it is thrown up.
by beaters J and afterwards escapes at the sides of the baffle plate M and falls
from the machine amongst that which fell direct. The baffle plate M is to divert
any return blast downwards through the perforated bottom of the recess and thus
prevent any of the impurities returning and mixing with the cleansed cut chaff or
fodder.
The impurities expelled at B, K and L are all carried away by the inclined
casing N.
Having now particularly described and ascertained the nature of my said inven- .
tion and in. what manner the same is to be performed I declare that what I
claim is
The general arrangement construction and combination of the various parts.
forming improvements in or connected with cut chaff or fodder cleaners and.
separators substantially as herein set forth.
Dated this Eleventh day of August 1894.
