page_text: I, JAKOB STALDER, of Oberburg, in the Canton of, Berne, Switzerland, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following.
statement:-
In all mowing machines heretofore in use it has been necessary to put the
driving apparatus out of gear independently of the lifting of the cutting apparatus,
and this has rendered the manipulation of the machine difficult.
r
The object of the present invention is to provide mechanical means whereby the
putting in and out of gear of the driving apparatus is effected by the lowering
and lifting of the cutting apparatus.
The mechanical devices for effecting the object of the invention may be varied
considerably. One method of carrying the invention into effect is illustrated in
the accompanying sheet of Drawings, in which Figure 1 is a partial side elevation
of a mowing machine with my invention applied thereto, Figure 2 a portion of
Figure 1 showing certain of the parts in different positions, Figure 3 a plan
corresponding to Figure 1, and Figure 4 a detail view of part of Figure 4.
A is the lifting handle of the cutting apparatus with the cast iron shoe B
pivotted to the support E, and having an eye C therein to which the cutting
apparatus is connected. D is the fulcrum pin in the support E for the shoe B.
The support E is bolted to the draught pole F.
On the main axle is fixed a spur wheel G which gears with a pinion H. This
pinion is loose on the shaft J and is furnished with claws or teeth on the side of
its boss. The bevil wheel. K which is fixed on the same shaft has similarly
formed but oppositely set claws or teeth with which the claws or teeth of the
pinion H can be geared and ungeared. The movement of the pinion H for the
purpose of being coupled with the bevil wheel K is effected by means of a ring N,
which turns on a flange running round the boss of the pinion H, and is furnished
at the top with a lug and at the bottom with a pin which slide in oblique slots
in the casing o of the wheel K, when the ring N is turned. The arrangement of
oblique slots is shown in Figure 4, in which the slot shewn in dotted lines,
receives the pin of the ring N whilst the lug extends out through the upper slot
shown in full lines.
Above the mowing machine is mounted a shaft L, one end of which turns in
a bearing in the support E, whilst the other end is guided in the support M.

page_text: On the end of the shaft L and by the side of the support M is secured a lever L',
and on the opposite end a lever L².
Further there is on the shaft La-spiral spring Q which is fixed at one end to
the support M, and at the other end is connected to a rotatable and adjustable
ring or collar R by means of which the tension of the spring can be varied as
may be required.
This spring acts upon the lever L in such manner that the latter presses
the connecting rod P to the right and turns the ring N by means of its lug
thereby pushing the claw coupling into gear; this working position of the
machine is shown in Figure 1.
ני
When work is to be stopped the conductor operates the lever A. from his seat D
so as to bring it into the position shown in Figure 2. This movement of the
lever A brings the eye C in the shoe E into its hghest position' and the cutting
apparatus suspended thereto is raised from the ground.. A stop-pawl B¹, the
fulcrum 12 of which is fixed to the shoe B, is pressed by a spring B³ into a notch
in the support E and holds the cutting apparatus in the elevated position clear
of the ground.
The fulcrum pin B projects beyond the stop-pawl B', and takes with it the
lever L3 on the shaft L when the lever A is turned, thereby turning the shaft L
through a certain angle and stretching the spring Q; the connecting rod P is
consequently drawn to the left by the lever L', and the other end of this rod,
which is connected with the lug on the ring N transmits to the latter the rotation
necessary for throwing the claw coupling out of gear.
Having now particularly described and ascertained the nature of the said in-
vention,, and in what manner the same--is to be performed; I declare that what I
claim is
The improvement in mowing machines which consists in so connecting the
device for lifting and lowering the cutting apparatus with the driving apparatus,
hy mechanical means, that when the cutting apparatus is lifted the driving
apparatus is put out of gear, and when lowered the same is put into gear, sub-
stantially as described.
