Improvements in Chaff-cutters.
I, MARTIN PIERCE, of Mill Road Iron Works, Wexford, in the County of
Wexford, Ireland, Agricultural Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to chaff-cutting machines and has for its object to simplify
the construction of the mechanism for transmitting motion to the rising and
falling feed-roller without using the complicated universal joints hitherto generally
employed.
According to my invention the ends of the driving shaft and the roller-shaft are
cut or slotted to form four quadrantal teeth. In connection with these slotted
ends I make use of a connecting shaft the ends of which have quadrantal portions
removed therefrom so as to leave solid portions which will enter the slots in the
shaft ends.
The ends of the connecting shaft work freely in the slots in the shaft ends so
that the feed roller will be free to rise and fall relatively with the driving
shaft.

Improvements in Onan-cutters.
I, MARTIN PIERCE, of Mill Road Iron Works, Wexford, in the County of
Wexford, Ireland, Agricultural 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:-
My invention relates to chaff-cutting machines and has for its object to simplify
the construction of the mechanism for transmitting motion to the rising and
falling feed-roller without using the complicated universal joints hitherto generally
employed.
According to my invention the ends of the upper-roller driving shaft and the
roller-shaft are cut or slotted to form four quadrantal teeth. In connection with
these slotted ends I make use of a connecting shaft the ends of which have
approximately quadrantal portions removed therefrom so as to leave solid portions
or teeth which will enter the slots in the shaft ends.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a front elevation of so much of a chaff-cutting machine as is necessary
to illustrate my invention:
Figure 2 is a plan view shewing the parts constituting my invention separate:

page_text: Figure 3 is a view of one of the slotted shaft ends; and,
Figure 4 is a view of one end of the connecting shaft.
a is the frame of the chaff-cutter and b, b are the feed rollers the upper of which
slides in guides in the usual manner.
c is the upper roller driving shaft which receives its motion in the usual manner
and which has its end slotted at d, d as shewn in Figure 3 to form the quadrantal
teeth e, e.
fis the shaft of the upper feed roller the end of which is slotted in the same
manner as the shaft c; and g is my connecting shaft the ends of which have
approximately quadrantal portions removed as shewn in Figure 4 so as to form
the teeth h, h which fit into the slots d, d between the teeth e, e as will be readily
*understood.
In practice the slots d, d are made wider than the teeth h, h so that the ends of
the connecting shaft will work freely in the said slots whereby the feed roller will
be free to rise and fall.
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 :-
1. In a chaff-cutter, transmitting motion to the rising and falling feed roller
through the medium of a shaft the ends of which are formed with teeth (h, h)
fitting into corresponding slots (d, d) in the ends of the upper-roller driving shaft
and the feed roller shaft, substantially as described.
2. The improvements in chaff-cutters herein before described and illustrated in
the accompanying drawing.
