mit the hoe to pass over the obstructions.
This abnormal movement of the standard
causes the arms 18-19 and their attachments
to swing upon the pivot 17 and assume the
5 position shown in dotted lines Fig. 1, which
represents the position of the parts when the
hoe is passing over obstructions, as above
noted. By this simple means the inclination
of the hoe may be readily adjusted to any re-
10 quired extent, to quickly adapt the device to
the condition of the ground or the plants
which are being cultivated.
Cultivators of the class described are
usually provided with a plurality of beams
15 10, and each of the beams will be provided
with its separate and independent hoe ad-
justing mechanism, as will be. obvious, but
these parts are not shown as they form no
part of the present invention.
20 The lever 21 is within easy reach of the
driver upon the seat of the cultivator, not
shown, so that the adjustments can be ac-
complished without stopping the team. It
frequently happens that it is desirable to
25 change the position of the hoes at different
points in the same row, and this can be read-
ily accomplished by the driver by manipu-
lating the levers 21 from his seat, and with-
out stopping the team.
3o What is claimed is
1. The combination with a cultivator beam
of a standard swinging from the beam and
carrying a cultivator hoe, an arm swinging
from said beam, an operating lever pivoted
35 to said swinging arm, means for locking said
lever to said swinging arm, a link bar con-
necting said lever and standard, and means
for maintaining said link bar yieldably in
its upper position.
40 2. The combination with a cultivator
beam of a standard swinging from the beam
and carrying a cultivator hoe, an arm swing-ing from said beam, an operating lever piv-
oted to said swinging arm, a link bar be-
tween said lever and standard, means for 45
locking said lever to said swinging arm, a
bracket connected to said beam, and a spring
upon said bracket and operating to maintain
said link bar yieldably in its upper position.
3. The combination with a cultivator 50
beam of a standard swinging from the beam
and carrying a cultivator hoe, an arm swing-
ing from said beam, an operating lever piv-
oted to said swinging arm, means for locking
said lever to said swinging arm, a link bar 55
between said lever and standard and pro-
vided with a longitudinal slot, a bracket ex-
tending rearwardly of said beam, a bolt ex-
tending .through said bracket and slidably
engaging said link bar slot, and a spring stir- 60
rounding said bolt and engaging said bracket
and operating to maintain said link bar
yieldably in its upper position.
4. The combination with a cultivator beam
of a standard swinging from the beam and 65
carrying a cultivator hoe, an arm swinging
from said beam, an operating lever pivoted
to said swinging arm, means for locking said
lever to said swinging arm, a bracket extend-
ing rearwardly of said beam, a link pivoted 70
at one end to said beam and bearing beneath
said bracket and provided with a lateral pin
at its free end, a spring engaging said bracket
and operating to maintain said link yield-
ably in its upper position, and a link bar con- 75
nected at its ends to said lever and standard
and provided with a longitudinal slot slid-
ably engaging over said pin.
In testimony whereof, I affix my signature,
in presence of two witnesses.
