43 depending from the tongue 13. On the
outer end of the shaft 37 is fixed a hub 44
having a flange 45 formed thereon and to
this flange are secured arms 36 each bearing
5 a chopping hoe 47.
In order to permit the lip 30 being sprung
out of its engaging notch the pivot pin of
the lever 27 is relatively long and is pro-
vided with a nut in spaced relation to the
10 lever. Between this nut and the lever there
is provided a spring 48 which normally
holds the lever in such position that the lip
engages a notch.
It is to be noted that the teeth on the re-
15 spective gears 23 and 40 are somewhat loose
in mesh so that variation in angularity with
the change in the diameter obtained by mesh-
ing With the various series 24 will be per-
mitted.
20 In the operation of the device when it is
desired to shift from one row of teeth 24 to
another, the lever 27 is manipulated to com-
press the spring 21 and force the gear 23
to the left of Fig. 1. Then the lever 42 is
25 moved to bring the gear 40 into position for
mesh with the desired row of teeth 24.
Thereupon the lever 27 is again moved to
permit such meshing..
It is to be noted that by reason of the pe-
30 culiar yoke and arch bar construction the
thrust of the spring under compression is
taken up not only by a single collar but also
by the collar 17 at the opposite end, the arch
bar and yoke thus aiding iii strengthening
35 the device.
When it is desired to raise or lower the
chopper blades it will be obvious that the
lever 32 is used.
The device is provided with the usual
40 standard 50 and driver's seat 51 and the
driver having taken position thereon the
machine is driven to the field. When the
gears have been properly adjusted the ma-
chine is driven so that the growing plants
45 pass between the wheels, whereupon the ro-
tation of the chopper blades will remove the
plants at intervals, thus allowing room for
the growing plants and thinning the crop.
There has thus been provided a simpleand efficient device of the kind described, 50
and for the purpose specified.
It is obvious that many minor changes
may be made in the form and construction
of this invention without departing from the
material principles thereof, and it is there- 55
fore not wished to confine the invention to
the exact form herein shown and described,
but it is wished to include all such as prop-
erly come within the scope claimed.
Having thus described the invention, what 60
is claimed as new, is:
In a device of the kind described, an axle,
a pair of wheels supporting said axle, one
of said wheels being fixed thereon, spaced
collars on said axle, a yoke having its ends 65
pivotally mounted on said axle and bearing
against said collars, an arch bar having its
end mounted on said axle and bearing
against the equal faces of the yoke ends, a
tongue extending forward from said arch 70
bar, a collar on said axle bearing against one
of the ends of the arch bar, a ratchet member
splined to said axle, a spring bearing at one
end against the last mentioned collar and at
the other end against said ratchet member, 75
a hub provided with ratchet teeth coacting
with the teeth on the ratchet member, a
gear carried by said hub and provided with
concentric series of beveled teeth, a grooved
collar slidably mounted on said axle and 80
bearing against said hub, a cross bar con-
necting the arms of the arch bar, a shipper
lever pivoted thereto and engaging the
grooved collar, a bar depending from said
tongue and having its lower end slotted, a 85
cuff slidably mounted on said bar, a shaft
journaled in said cuff, a yoke mounted on
said axle, a gear fixed on said shaft, means
to move said shaft longitudinally, means to
raise and lower said cu , and chopper blades 90
carried by said shaft.
In testimony whereof I hereunto affix my
signature in presence of two witnesses.
