PROVISIONAL SPECIFICATION.
Improvements in or applicable to Chaff Cutters.
1, EDWARD SCALES, of Seaton Grange, in the County of Rutland, Farmer,
do hereby declare the nature of this invention to be as follows:-
My invention has for its object to provide means whereby the feed mechanism
of chaff cutters, and especially large chaff cutters driven by steam or horse power
can be readily reversed or thrown out of gear by the attendants without their
having to move from their position beside the feed box.
In carrying out my invention Imount on the frame of the chaff cutter a
pivotted bar, one end of which is connected with the feed mechanism by suitable
levers and rods, whilst the other end is connected to a lever pivotted upon the
feed box in such a manner that when the lever is depressed the feed mechanism
will be operated.
A pawl or catch is provided for retaining the lever in the required position.

I, EDWARD SCALES, of Seaton Grange, in the County of Rutland, Farmer,
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 has for its objeet to provide means whereby the feed mechanism of
chaff-cutters, and especially large chaff-cutters driven by steam or horse-power can
he readily reversed or thrown out of gear by the attendant without having to move
from his position beside the feed box.
In carrying out my invention I mount on the frame of the chaff-cutter a pivotted]
bar, one end of which is connected with the feed mechanism by suitable levers and
rods, whilst the other end is connected to a lever pivotted upon the feed box in
such a manner that, when the lever is depressed, the feed mechanism will be
operated.
A pawl or catch is provided for retaining the lever in the required position.
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 side elevation; and,
Figure 2 a plan of a chaff-cutting machine having my improvements applied
thereto.
a is the frame of the machine, is the driving shaft carrying the knife wheel c,
d is the feed box, and e, e are the feed rollers which are driven from the shaft b
through the medium of the gear wheels f, and 9 and other suitable gearing, the
011

page_text: wheels being loosely mounted upon the shaft b and having arranged between
them the clutch rotating with the shaft but adapted to slide thereon so as to
engage with clutch teeth on either of the wheels, or f', whereby motion may be
communicated to the feed rollers in one or the other direction as desired; all of
which parts being arranged in a well known manner require no further description.
is my lever which is connected to the feed box and through the medium of
which the clutch & in connection with the feed mechanism will be operated so as to
disengage the said clutch from the wheel (with which it normally engages
during the working of the chaff-cutter) and move it into engagement with the
wheel whereby the feed rollers will be rotated backwards. "As shewn in the
drawing this lever is represented as a spring-lever connected to one edge of the feed
box d but if desired it may be arranged to work upon a pivot. The motion of the
lever is communicated to the clutch through the lever mounted on one end of
a shaft and carrying at its other end a lever I having a pin which enters a
circumferential groove in the clutch in a well known manner. The lever is
provided with an arm or extension m to which one end of a spring is connected,
the other end of the spring being connected to the framing a in such a manner that
the said spring normally tends to retain the lever and consequently also the
lever in its uppermost position. o is the pawl adapted when the lever i is
depressed to enter a notch in an arm on the said lever and to retain the latter in
its depressed position against the pull of the spring n.
With the arrangement hereinbefore described it will be obvious that should the
attendant of the machine have his hand caught by the rollers e, e he can by lenning
forward on the lever i depress the latter whereby the clutch will be moved to
stop the feed rollers, or cause them to move in the reverse direction, thereby
obviating the liability of his arm being drawn into the machine.
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 chaff-cutter the arrangement upon the feed box of a lever arranged
in connection with the clutch of the gearing for driving the feed mechanism in
such a manner that, by leaning forward on the said lever, the feed mechanism
can be stopped, or the direction of rotation reversed, substantially as described.
2. The combination with the feed mechanism of a chalf-cutter, of a lever such
as i arranged in combination with the clutch through the medium of which the
motion of the driving shaft is communicated to the gearing for driving the feed
mechanism, substantially ns, and for the purpose, described.
