The improvements relate to guards to be supplied to present or specially con-
structed forage and chaff cutting machinery, whereby their rollers and cutters may
be prevented from mutilating persons working said machinery or otherwise.'
The improvements consist in the application and use of counterpoised bars or
levers furnished with a connecting rod arranged to actuate the stopping lever, in
general use on all chaff cutters, whereby the clutch of the driving gear is thrown.
out of contact and the machinery immediately stopped, the bars being so shaped
and placed that they can be actuated by the arm or body of the person serving
the machine, and so provide ready and effective means by which the person
serving the machine may in the event of both his hands becoming entangled, stop
the machinery and release himself.

by Michael Honold, of Eislingen, in the Empire of Germany.
The improvements relate to guards to be supplied to present or specially con-
structed forage and chaff cutting machinery, whereby their rollers and cutters may
be prevented from mutilating persons working said machinery or otherwise.
The improvements consist in the application and use of counterpoised bars or
levers furnished with a connecting rod arranged to actuate the stopping lever in
general use on all chaff cutters, whereby the clutch of the driving gear is thrown
out of contact and the machinery immediately stopped, the bars being so shaped
and placed that they can be actuated by the arm or body of the person serving
the machine, and to provide a ready and effective means by which the person
serving the machine may in the event of both his hands becoming entangled stop
the machinery and release himself.
The accompanying Drawings will serve further to explain the Invention, Fig. I.
being side view of my apparatus while the machine is in activity; Fig. II., a side
view when the machine is stopped by the apparatus; Fig. III., a front view and
partial section; and Fig. IV., a plan.
Similar letters indicate corresponding parts.
The Invention consists in the combination of the bow a, the connecting rod b,
the lever c keyed on the same shaft with the clutch lever e to get the machine in or
out of gear. This apparatus is attached to an English or similar forage-cutting
machine in order to prevent accidents, such as cutting the hands of the user by the
knives.
If a hand of the person serving is caught by the rollers of the machine, the person
must with his arm press the bow a upwards, thereby moving the connecting rod b,
the lever c, and the lever e, so as to bring the clutch of the driving gear out of
contact (Fig. II.), and to cause an instantaneous stoppage of the machine, after which
the person can easily release his hand from the straw rollers.
The stopping lever c now used on every English cutting machine is not self-
acting, in consequence of which many accidents arise to the user, who, on having
both hands caught by the rollers, is unable to stop the machine, while, if only one
hand is caught, the person has frequently not sufficient presence of mind to seize
the lever e but tries to get the hand out.
In order to prevent the driving gear from coming again in motion, the seg-
ment dis provided with a catch, and the bow a is continued beyond its fulcrum,
forming a bent lever which carries a weight.
This apparatus can be adapted to any forage-cutting machine.

same shaft with the clutch lever e in contact with the clutch, and the seg-
ment d, the whole forming a self-acting safety apparatus applied to forage-cutting.
