3018, the pinion 12, upon the rear extremities o
of the hoe shafts, may be thrown into or out t
of mesh with the gears 11 thus making it i
possible to discontinue the operation of the 3
hoes without bringing the vehicle to a stop. v
It will be observed that a plurality of holes a
20 are provided to the links 19 at their up- s
per extremities, the object of these holes t
being to allow the operating length of the d
links to be increased or decreased, according b
to the adjusted position of the rear wheels r
with their attached gears 11. S
The forward extremities of the hoe shafts t
are rotatably supported in bearings 21, at- t
tached to the lower extremities of curved
springs 22. The upper extremities of these s
springs are supported from sliding blocks I
23, mounted upon transverse rods 24. These
rods extend into suitable apertures 25, in the4
enlarged. outer extremities of bars 26, the t
inner extremities of the bars being pivoted
upon a horizontal pin 27. Two of the aper-
tures 25 are provided to each bar, allowing
vertical adjustment of the normal operating
positions of the hoe shafts, by placing theI
rods 24 in either of these apertures. The
pivotal pin 27 is mounted in a U shapedI
standard 28 attached to the middle beam 3.
The hoe shanks 13a are radially attached to
a disk 13b rigidly mounted upon the hoe
shaft. The hoe blades are formed by turn-
ing the extremities of the shanks at a right
angle and putting a cutting edge upon the
same. While in the drawing, only two hoes
are shown attached to the disk, it is to be
understood that any desired number may be
placed thereon.
A cross bar 29 is mounted centrally upon
the beams 3 to the rear of the bars 26, and
is provided with reduced arms 30 at either
side, upon which arms levers 31 are pivoted.
These levers serve the double purpose of
raising the forward extremities of the
hoe shafts, or displacing said extremi-
5 ties transversely of the machine. To pro-
duce the former effect the levers are oper-
ated vertically, while in the latter case, the
levers are manipulated horizontally their
displacement upon the arms 30, being pre-
0 vented by pins 32 in said arms on either side
of the lever. A second pair of the pins 32a
are shown in each arm, nearer the outer ex-
tremities of the arms 30, to indicate the op-
erating position of the lever for wide rows,
5 when the wheels are in their outermost po-
sition of adjustment. Slots 33 are provided
in the levers to receive the arms 30, thus
allowing the levers plenty of longitudinal
play. These levers enable the operator of
0 the machine to quickly adjust the hoe shafts
vertically, or laterally, thus adapting the
hoes to inequalities of the ground or di-
vergencies of the cotton rows. A lever 34
is also provided on the machine swinging
5 longitudinally therewith, whereby both setsf hoes may be simultaneously adjusted ver-
ically, and held in adjustment. This lever
s pivoted upon a segmental, curved rack
5, carried by a middle beam 3, and is pro-
ided with the usual spring - pressed rod 70
dapted to engage this rack. A pair of
winging rigid links 36 connects lever 34 to
he horizontal portion of a. bent rod 37 the
lownturned extremities of which are em-
)edded in the rocker shaft 38. Bearings 39, s
mounted upon the outer beams 3 rotatably
upport the rocker shaft. At each side of
he rocker shaft an arm 40 extends rigidly
hereinto, the outer extremities of these arms
being curved as shown in Fig. 5. Vertical so
lots 41 are provided in each of the pivoted
bars 26, and suitable arms 42 extend up-
wvardly into these slots the lower extremities
13 of the arms being bifurcated to receive
the loops in the lower extremities of the 85
arms 40. Obviously when the lever 34 is
manipulated the rocker shaft 38 is rotated,
imparting an upward motion to the extremi-
ties of arms 40 and thus causing the bars 20
to swing upward about their central pivot io
27. The bars are guided in this motion by
U shaped attachments 44, one of which is
attached to each of the outer beams 3.
Since the hoe shanks are not permanently
attached to the disks 13b, they may be ex- 95
changed when desired for longer shanks or
shanks carrying larger hoes.
The advantage of having the distance be-
tween the transporting wheels adjustable on
each axle is readily apparent as the machine 100
can thus be adapted to run between rows
spaced at any ordinary distance apart.
I am aware that changes may be made in
the form and proportion of parts, and de-
tails of construction of the device herein de- 105
scribed and shown as the preferable em-
bodiment of my invention, without depart-
ing from the spirit or sacrificing the ad-
vantage thereof and I therefore reserve the
right to make such changes and alterations t o
in said device as fairly come within its scope.
What I claim is:
1. In a cotton chopper, the combination
with the frame thereof, and transporting
wheels, supporting the same, of a rotatably 1 5
mounted, flexible shaft extending longitu-
dinally of the cotton chopper at each side
thereof, mechanism communicating rotation
to said shaft, means whereby the communica-
tion of such rotation may be interrupted, ]20
means whereby the forward extremities of
the shafts may be separately elevated, a set
of hoes mounted to rotate with each shaft,
means whereby the working positions of
each set of hoes may be laterally adjusted, 1225
and means whereby said working positions
may be simultaneously adjusted vertically
and held. in adjustment, substantially as
described.
