PROVISIONAL SPECIFICATION.
Improvements in and connected with Chaff Cutters.
I, TIMOTHY SABINE of Brook House, Swadlincote in the County of Derby.
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide certain improvements in and connected
with chaff cutters the said improvements relating to the bagging of the chaff as it
comes from the cutters, and being more particularly applicable to portable chaff
cutters.
As now generally constructed a chaff cutter frequently takes up too much room
when used in the stackyard or elsewhere and moreover the person or persons
attending to the bagging is or are exposed to considerable annoyance from the dust
and small particles which, as the paddles travel round and pass the chaff into the
bonnet and downwards into the bag and the wind or blast blows on top of the chaff
in the bag, are caused to fly upwards and around and cause the annoyance above
mentioned. To obviate these difficulties, instead of having a bonnet or the like at
the front of the paddle box or casing I arrange a conduit or covered trough to pass
from the upper side of the paddle box, the paddles being in this case not twisted as
would be necessary in the case of their being required to pass the chaff into the
bonnet, the said paddles constructed and arranged according to my invention simply
pass the chaff straight along the trough or conduit to a worm mounted in suitable
bearings and revolving inside a casing placed preferably along the side of the said
chaff cutter; the worm is driven in any suitable manner from the driving parts of
the chaff cutter. In the bottom of the worm casing I arrange a suitable number
of openings for bagging which may if desired be made adjustable and capable of
being closed at will by either a flap or sliding door or cover. I may
also arrange
sieves or screening devices in or connected with the said bagging openings underneath
the worm, to allow of chaff of a certain size being bagged at certain openings.
I find by these improvements that there is no annoyance to the person or persons
attending to the bagging, the fine dust and particles travelling along between the
worm and the upper part of its casing and so forwards and out at the end of the
said casing.
It is evident that when a bag has been filled at the first opening its door or cover
may be closed and still the chaff cutter proceed in its work and pass chaff to the
next opening or openings and that at one and the same time chaff of different sizes
may be bagged at different openings. For convenience of cleaning out or otherwise
getting at the worm, the upper part of the worm casing may be hinged or formed
as a loose lid if required.
Dated this 13th day of September 1894.

page_text: Improvements in and connected with Chaff Cutters.
I, TIMOTHY SABINE of Brook House, Swadlincote, in the County of Derby,
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 :-
The object of my invention is to provide certain improvements in and connected
with chaff cutters, the said improvements relating to the bagging of the chaff as it
comes from the cutters, and being more particularly applicable to portable chaff
cutters.
In describing my invention reference will be had to the accompanying sheet of
drawings which will be deemed to form a part of this Specification.
Figure 1 is an end elevation partly shewing the application of my invention to a
portable chaff cutter.
Figure 2 is a side elevation of the same.
Figure 3 is an enlarged section on line a a of Figures 2 and 4.
Figure 4 is an enlarged part side elevation shewing one of the bagging openings
to be hereafter described.
Figure 5 is an enlarged part section on line b. b. of Figure 1.
It will be understood that my invention is applicable to almost any power driven
portable chaff cutter and I have therefore partly on this account and partly to avoid
confusion, only shewn those parts of the chaff cutter which are absolutely necessary
for the illustration of my invention.
As now generally constructed a chaff cutter frequently takes up too much room
when used in the stack yard or elsewhere, and moreover the person or persons
attending to the bagging, is or are exposed to considerable annoyance from the
dust and small particles which, as the paddles travel round and pass the chaff into
the bonnett and downwards into the bag and the wind or blast blows on the top. of
the chaff in the bag, are caused to fly upwards and around and cause the annoyance
above mentioned. To obviate these difficulties or disadvantages, instead of
employing a bonnett or the like at the front of the paddle box A. I arrange a
conduit or covered trough B to pass from the upper side A' of the paddle box, the
paddles C being in this case not twisted as would be necessary in the case of their
being required to pass the chaff into the bonnett. I prefer to fix my paddles C. to
a wheel or the like M separate from the ring or wheel N carrying the cutters, the
wheel M and paddles C however revolve with the cutter wheel N the former having
fixed to it a pin C (see Figure 5) which passes through a hole in the cutter wheel N
and is kept therein by means of a nut on the shaft P. The cutters are not shewn
upon the drawings but the feed opening Q through which the hay or straw passes
is indicated upon Figure 1. The said paddles constructed and arranged according
to my invention as shewn upon the drawings simply pass the chaff straight along
the trough or conduit B. to a worm D the shaft of which is mounted in suitable
bearings E and revolves inside a casing F placed preferably along the side of the
said chaff cutter; the worm D is driven in any suitable manner: such as by means
of a belt on pulley G from the main driving parts of the chaff cutter.
In the bottom of the worm casing I arrange a suitable number of openings T for
bagging (see Figures 2, 3 and 4) which may if desired be made adjustable and
capable of being closed at will by either a balance weighted flap H or a sliding door
or hinged inverted lid. I may also arrange sieves or screening devices 1 (see
Figure 3) in the said bagging openings underneath the worm, to allow of chaff of a
certain size being bagged at certain openings the said sieves or screening devices
being movable as desired. Hooks K are placed in convenient positions about the
bagging openings for the purpose of hanging the bags upon when being filled.

page_text: Any suitable cover such as L may be provided for the top of the worm casing.
And the paddle box will also be provided with a cover not shewn upon the drawings
which will fit inside the hook R (Figures 1 and 5) and also be provided with a hook
or the like to fit in the notch or recess S; any suitable covers and means of fixing
same may however be provided for the paddle box and worm casing. The whole
may be carried by any suitable supports or stays from the main framework of the
machine.
I find by these improvements that there is no annoyance to the person or persons,
attending to the bagging, the fine dust and particles travelling along between the
worm and the upper part of its casing and so forward and out at the end of the
said casing.
It is evident that when a bag has been filled at the first opening its door or cover
may be closed and still the chaff cutter proceed in its work and pass chaff to the
next opening or openings and that at one and the same time chaff of different sizes
may be bagged at different openings. The end of the worm casing being preferably
left open there will thus be little or no danger of choking the paddle box and
stopping the machine through neglect in bagging at the different openings.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :
1. In a power driven portable chaff cutter the covered trough or conduit B, the
worm D revolving in any suitable bearings E and casing F and adapted to pass the
chaff to bagging openings T the latter being provided with sieves or screening
devices I if desired, balance weighted flaps H or other suitable devices being
employed to close the said openings substantially as described and illustrated.
2. In a power driven portable chaff cutter a paddle wheel M distinct and separate
from the cutter wheel N but adapted to engage and revolve therewith upon the
same shaft P, and having paddles C substantially as described and illustrated.
