PROVISIONAL SPECIFICATION.
Improvements in Chaff Cutters.
We, JOHN CHARLES FLOAT, Managing Director, and CHARLES ROBERT
GOWERS, Traveller, both of the Maldon Iron Works Company Limited, of
Maldon, Essex, Agricultural Implement Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in that class of chaff cutters in which
what is known as a "face wheel" is employed as part of the feeding mechanism,
the object of the invention being to provide for the reversing of the feed rollers as
and when required.
Now, according to our invention, we may employ any number of rows of teeth
on the face wheel, according to the number of different lengths of chaff it may be
desired to cut.
This wheel is driven by a slightly bevelled pinion mounted on and connected to
a sleeve so as to be capable of being shifted longitudinally thereon, to gear with any
particular row of teeth on the face wheel. This sleeve is mounted loosely on the
Hy wheel and cutter axle, which carries also a double clutch connected therewith so
as to be capable of sliding longitudinally thereon. On the other side of the clutch,
the axle has also a pinion mounted loosely thereon, for the purpose of reversing the
action of the feed. The clutch is moved in either direction by means of a lever or
handle extending to the opposite side of the machine, and so arranged that the
attendant may operate it in one direction, namely, to reverse, by pressing his body
against it.
The position of the driving pinion is regulated by hand in the usual way.
The present arrangement of feed driving mechanism is simple and economical,
and does not require an additional shaft, as the mechanism is all mounted on the
driving axle, and the necessity for shifting the driving axle away from the side of
the box is obviated.

Improvements in Chaff Cutters.
We, JOHN CHARLES FLOAT, Managing Director, and CHARLES ROBERT
GOWERS, Traveller, both of the Maldon Iron Works Company Limited, of
Maldon, Essex, Agricultural Implement Manufacturers, 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 :—
This invention relates to improvements in that class of chaff cutters in which
what is known as a "face wheel" is employed as part of the feeding mechanism,―
the object of the invention being to provide for the reversing of the feed rollers as
and when required.
Now, according to our invention, we may employ any number of rows of teeth or
cogs on the face wheel, according to the number of different lengths of chaff it may
be desired to cut.
This wheel is driven by a shifting pinion mounted on a sleeve, which is itself
mounted loosely on the fly wheel axle, which carries also a sliding double clutch and
a clutch pinion, for the purpose of reversing the action of the feed. The clutch is
moved in either direction by means of a lever or handle extending to the opposite
side of the machine,

page_text: The present arrangement of feed driving mechanism is simple and economical,
and does not require an additional shaft, as the mechanism is all mounted on the
fly wheel axle.
In the accompanying drawing,
Fig. 1 is a partial plan view of our improved arrangement of chaff cutter, and
Fig. 2 is a partial side elevation, showing the arrangement of gearing uncovered.
A is the frame of the machine, B is the feed trough, C are the feed rollers,
which are geared together as usual. D is the flywheel, with which the cutting
knives are combined in the usual way. D¹ is th riving or band pulley, and D
the fly wheel axle.
E is the "face wheel" (in the drawings provided with three rows of teeth or
cogs), provided at back with a pinion E, and mounted on a stud axle carried by
the frame. This pinion E¹ gears with a tooth wheel F on the axle of one of the
feed rollers C.
The face wheel is driven from the fly wheel axle through pinions as will now be
described.
Upon the axle D' is keyed, so as to be able to slide thereon, a double clutch G.
On one side of this clutch, and mounted loosely on the axle, is a sleeve G', provided
with clutch teeth. Upon this sleeve is keyed, so as to be capable of sliding thereon,
a pinion H, provided with a grooved collar to receive a fork or crutch I, provided
with a screw stem, which works through a slot in the casing, and is secured in the
desired position by a thumb nut I'
On the other side of the clutch G, and mounted loosely on the axle, is a clutch
pinion J, which is set to gear with either row of cogs on the face wheel, preferably
the middle one.
K is a lever pivotted to the side frame on the gear side of the machine, and
extending across to the other side, on which the attendant stands to feed the
machine. This lever K is pivotted to an arm L' extending from the rod L of the
clutch shifting fork M.
The length of chaff it is intended to cut having been decided upon, the pinion H
is shifted on its sleeve, to gear with the row of teeth corresponding to that length,
and it is fixed there by the thumb nut I'.
The lever K is then moved to the left, and the clutch G is thrown into gear with
the sleeve G¹, by which means the pinion H is driven, motion being thus communi-
cated to the face wheel E, and through the gearing to the feed rollers C.
Should reversing be necessary, the attendant, who will be on the left hand side of
the lever K, has only with his body to press the lever to the right, which will throw
the clutch into gear with the clutch pinion J, and the movement of the feed
rollers C will be immediately reversed.
The amount of movement of the lever K is not dependent on the length of the
chaff to be cut, as the sliding motion to be given to the clutch is always the same,
by reason of the use of the clutch sleeve G¹, which is permanently set.
In the position shown in the drawing, the machine is at rest, the clutch G being
midway between the sleeve G' and the clutch pinion J.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The arrangement of driving and reversing mechanism for chaff cutters herein
shown and described.
2. In driving mechanism for chaff cutters in which a face wheel is employed, the
combination with the fly wheel axle, driving pinion, and clutch, of a clutch sleeve
as and for the purpose set forth.
