wheel may continue to rotate, but the wheel
18 and its attached shaft 17 will come to a
state of rest.
Collars 27 are carried by the shaft 17, and
5 adj]ustably engaging the collars is a bar 25,
the collars being provided with set screws
26 to couple the bar to the shaft at any de-
sired point. At its lower end the bar 25 is
provided with two disks 28-29 spaced
10 apart. The lower disk 29 is provided with
upwardly directed diagonally opposite pro-
jections 30, while the upper disk 28 is pro-
vided with curved bars 31 hinged at 32 to
the upper disk. The bars 31 are maintained
1 yieldxably with their free ends in normal con-
tact with the projections 30 by springs 33.
An arm 34 is journaled upon the bar 25 be-
tween the disks 28-29 and is provided with
a cutting blade 35 at its outer end. The
20 blade is supported from the bar 25 by a
brace 3 which is journaled between stop col-
lars 37 on the bar. By this arrangement as
the shaft 17 and its connected bar 25 are
rotated the blade 35 will be rotated there-
25 with.
Inasmuch as the shaft 17 is inclined for-
wardly and downwardly, the bar 25 has a
similar inclination, and the blade 35 is po-
sitioned at such an angle with relation to
30 the bar 25 that when it is behind the bar it
is in a position approximately parallel with
the surface of the soil. but when it is in
front of the bar it is at a decided angle with
relation to the surface of the soil.
35 In operation, the cultivator frame with
the attachment applied is moved along a
row of standing plants, and as the bar 25
rotates the blade 35 is carried around and
as it crosses the line of draft of the machine
40 behind the bar 25 it comes in contact with
the plants standing in the row and chops
the same out. As the said blade 35 swings
around in front of the bar 25 it is lifted
above the standing plants by the arm 34
45 which is also turning with the bar 25 and
therefore as it crosses in front of the bar 25
it does not encouiitcr the plants. As the I
blade 35 strikes the plants or surface of the
gronid behind the bar 25, the spring 33 will
50 give suficiently to prevent the force of in-
pact between the blade and the ground from
jarring or subjecting the attachment to
pounding. By adjusting the lever 22 andat the same time permitting the gear wheel
18 to remain in mesh with the pin 15 the 55
blade may be caused to cut deep or shallow
in the soil, as desired, and by moving the
lever 22 so that the wheel 18 is carried out
of mesh or above the pins 15 the blade 35
will come to a state of rest and thus the 60
chopping operation is interrupted.
When the blade 35 comes in contact with
the ground or the plants one of the bars 31
and the projection under the same are in
contact with the arm 34 and inasmuch as the 65
bar 31 may swing against, the tension of the
spring 33 the blade will cut out the plants
with a yielding stroke which will avoid ex-
cessive jarring of the attachment. If, how-
ever, the blade should strike an obstruction 70
in the ground through which it could not
penetrate, the spring 33 will yield suffi-
ciently to permit the bar 31 to swing away
from the projection 30 so that the said bar
and projection may pass by the bar 34 and 75
the said bar will come to a state of rest while
the bar 25 continues to turn. After the
blade 35 has passed beyond the said ob-
struction the bar 34 is encountered by the
other bar 31 and the projection 30 and the 80
blade 35 will continue to operate so long as
the conditions at the surface of the ground
remain favorable.
Having thus described the invention what
is claimed as new is: 85
In combination with a wheel mounted
frame, a cotton chopper comprising a for-
wardly and downwardly disposed bar jour-
ialed for rotation, means for rotating the
same, a resiliently supported blade carried 90
at the lower end portion of the bar and
arranged to approach the surface of the soil
as it passes behind the bar and arranged to
move away from the surface of the soil as
it moves in front of the bar, and a brace 95
connected at its outer end with the outer
end of the blade and journaled at its inner
end upon the bar, said bar carrying collars
which receive said brace between them.
In testimony whereof I affix my signature 100
in presence of two witnesses.
