SAMUEL LONG Agricultural Engineer Fulbourn, Cambridge do hereby declare the
nature of my Invention for IMPROVEMENTS IN CHAFF CUTTERS FOR ELEVATING
THE CUT MATERIAL INTO BAGS, CARTS, OR OTHER RECEPTACLES to be
follows:-
08
In order to accomplish the object of the Invention it is necessary to enclose the
fly wheel of the chaff cutter in a circular case of wood or suitable material with
the periphery or rim of sheet iron, zinc or other bendable material the said case to
be extended, say five inches in front of the fly wheel to allow a fan or revolving
elevator to work freely in the above named case, which case may be fixed to the
main framing of chaff cutter.
This case is to have an opening in the top or any other position to which
opening is hinged or fastened a trunk or conducter, made to any desired length for
directing the passage of the cut material as it falls from the knives and forced along
this trunk or conductor into bags carts &c., this trunk or conductor may have a
double spout at the further end to alternately fill one bag at a time to prevent
losing the cut material or stopping the machine the top end over the spout may be
provided with a grating of perforated zinc or other metal to allow the exhausted
air, dirt &c. to escape into the atmosphere.
In order to convey the cut material through this trunk or conductor it is
necessary to use a fan or revolving elevator and my main object in the Invention
is the construction. and working the same.
I propose to construct my fan with a centre boss, and any number of arms say
four or five, to the ends of these arms are attached blades or spoous as in ordinary
fans-this fan or revolving elevator to be the same size in circumference as the
ordinary fly wheel the said fan or revolving elevator to work inside the case
containing fly wheel and to work free and independantly on the spindle or axle of
the fly wheel.
In order to give the said fan or revolving elevator an increased speed which is
necessary to force the cut material along the trunk or conductor, as it falls from
the knives and is caught by the blades or spoons, I propose to fasten or key a

page_text: pulley on the main spindle of chaff cutter, this pulley with belting or other power
to give motion to a pulley on intermediate spindle fixed in any convenient position
say on legs of chaff cutter, this intermediate spindle with another larger pulley
attached is intended to give motion to the fan or revolving elevator to the boss or
centre of which is fastened a smaller pulley, to receive the belting or other power
transmitted from intermediate spindle-this style of driving power will give the
required speed to the fan or revolving elevator necessary to force the cut material
as it leaves the knives along the trunk or conductor, and thence down the spouts
into bags, or elevated high enough into carts, or other recepticles.
The necessary speed of fan or revolving elevator may he regulated by increasing
or reducing the sizes of pulleys on intermeadiate spindle according to the power
which gives motion to the chaff cutter itself.

page_text: SAMUEL LONG Agricultural Engineer Fulbourn Cambridge do hereby declare the
nature of my Invention for IMPROVEMENTS IN CHAFF CUTTERS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This Invention has for its principal object the depositing of the cut material as
it falls from the knives of the ordinary chaff cutter into bags carts or other
receptacles instead of falling to the ground and thence having to be collected up
and removed by hand, absorbing a large amount of labor and also involving loss of
the cut material by being trod on by the attendants, and the action of the fly
wheel throwing the cut material in all directions, my Invention has for its object
the removal of these complaints.
In order to attain this I propose to enclose the ordinary fly wheel of the chaff
cutter in a case in which is made to revolve a fan or revolving elevator which
catches the cut material and forces or propels it along a trunk or conductor and
thence into bags carts or other receptacles.
Having thus briefly described my Invention I will now proceed more fully to
explain the particulars by the accompanying Drawings all unnecessary com-
plication of the Drawings being avoided by the omission of those parts of the
machine to which my Invention does not directly refer.
Fig. 1. is a side view facing the fly wheel of an ordinary chaff cutter mounted on
travelling wheels A, with fly wheel B working inside the framing. C.-D shows
the usual position of the face through which the material to be cut passes as it is
fed up to the knives E.
Reference having been briefly given to the old parts of the machine I will now
proceed to describe my new Invention.
In order to accomplish the object of the Invention it is necessary to enclose the
fly wheel B in a circular case of wood or suitable material marked F in Fig. 2.
the periphery or outside rim may be of sheet iron or other bendable material.
The said case to be extended say about five inches in front of the fly wheel B to
allow a fan or revolving elevator Fig. 3. to work freely in the above named case
which case may be fixed to the main framing of the machine. This case is to have
an opening in the top at F. 1. or any other desired position to which is hinged or
fastened a trunk or conductor G at G. 1. made to any desired length for directing
the passage of the cut material as it fall from the knives and is forced along this
trunk or conductor into bags, carts, or other receptacles. This trunk or conductor
is provided with a mouth H having a double spout at the bottom H. 1. to
alternately fill one bag at a time without losing the cut material or stopping the
machine, to accomplish this, it is only necessary to turn the flap H. 2. hinged at
the bottom from one side to the other,
For delivering the cut material into carts I have arranged the wood trunk or
conductor G to be made telescopic and to draw out so as to extend to G. 2. as
shown by dotted lines, also for the mouth H to be taken off by the release of the
hooks H. 3.
The top end over the mouth of trunk or conductor may be provided with a
grating or ventilation of perforated zinc or other metal to allow the dirt from the
chaff and the exhausted air to escape into the atmosphere at G. 3.
The trunk or conductor may be elevated and kept in position by the rods G. 4.
The case F may be made to have the top half remove by releasing the
hooks F. 2. for convenience of repairs and sharping knives. The perforations
at F. 4. are to allow a free current of air to the fan or revolving elevator.

page_text: In order to convey the cut material through or along the trunk or conductor it
is necessary to use a fan or revolving elevator and the main feature in the
Invention is the mode of construction and working the same.
I propose to construct my fan or elevator Fig. 3. with a centre boss J. 1. and
any required number of arms. J. 2 to the ends of which are fastened blades or
spoons J. 3. J. 4. shows a perspective view of Same this same fan or elevator to be
the same size in diameter as the fly wheel and to revolve in the afore mentioned
case containing the fly wheel.
י.
This said fan or elevator to work free and independantly on the spindle to which
the fly wheel is fastened.
In order to give this fan or elevator an increased rate of speed which will be
necessary to force the cut material as it fall from the knives and is caught by the
blades or spoons-along the trunk or conductor and thence into bags or carts,
propose to fasten a pulley I on the fly wheel spindle this pulley by belting or
other equivalent to give motion to an intermediate spindle K. fixed in any con-
venient position, say on legs of chaff cutter, this intermediate spindle with another
larger pulley attached thereto by belting or equivalent to give motion to the said
fan or elevator to the boss of which is fastened a pulley of smaller dimensions K. 3.
thus by reducing or increasing the sizes of pulleys on intermediate spindle any
desired rate of speed may be attained.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I hereby declare that
what I claim is
First. The application of a fan' or elevator working in a case containing the
fly wheel of chaff cutter for the purpose, as herein before described."
Second. "In chaff cutters the arrangement of belt pulleys and intermediate
shaft for driving the said fan or elevator at any required rate of speed as herein
before described."
Thirdly. The application of the fan or elevator to revolve in either direction
freely and independantly on the fly wheel spindle of a chaff cutter.
