or openings may be made in the disk or wheel
adjacent to the periphery, as a substitute for
the cavities or recesses 30, and the horizontal
member of a spindle 27 is held at a prede-
5 termined angle to the foot-section of a hanger
by passing an adjusting-screw 31 or a pin
through a cavity 30 in the wheel or disk 29
after the spindle has been adjusted and into
the smaller opening 26 in the hanger adja-
io cent to that in which the spindle turns.
A disk chopper 32 is mounted to revolve
upon the horizontal member b' of each of the
angular spindles, and each disk chopper is
provided with a concaved inner and a con-
15 vexed outer surface, and these disk choppers
are held to turn on their spindles near the
hangers or removed therefrom through the
medium of pins 28', placed in openings 28 in
the said spindles, one at each end of the hub
20 of the disk, as shown in Fig. 4. The disk
choppers are therefore in pairs, a pair being
carried by each spindle, and the disk chop-
pers of each pair are placed with their con-
caved surfaces facing each other, and con-
25 verge at their rear ends and diverge at their
forward edges. Consequently the convexed
faces of the opposing disk choppers of ad-
joining pairs will converge at their forward
edges and diverge at their rear edges, as
30 illustrated in Fig. 1. All of the cotton con-
tained in a row of plants which will enter
between the concaved faces of each pair of
disk choppers will be cut out from the ground,
as shown in Fig. 1, leaving the hills of a
35 width corresponding to the distance between
the convexed surfaces of the disk choppers
at their forward edges.
The plows 33, which may be of any ap-
proved type, are secured to the lower rear
40 ends of the plow-stocks 22 and are immedi-
ately opposite the rear edges of each pair of
disk choppers, as is also shown in Fig. 1, and
therefore will be centrally placed between
the hills and will cultivate the ground at such
45 point. The foot of each plow-stock is to be
supplied with suitable automatic breaking-
joints or provided with the common break-
ing-pin.
The width of the hills is regulated by the
50 adjustment of the disk choppers on the spin-
dles 27, and since it is necessary that the
rows of hills shall be at even distances apart
when the disk choppers are adjusted the
ground-wheels of the machine should be cor-
55 respondingly adjusted, and the correct posi-
tion of the ground-wheels is that shown in
Fig. 1,wherein the wheels track centrally be-
tween the hills of adjacent rows. Therefore
if the disk choppers are adjusted to increase
6o or decrease the distance between the hills
and the supporting-wheels are not adjusted
the wheels wonld be liable to travel over the
cotton-plants that are designed to remain in
the ground, but the adjustment of the ground-
65 wheels prevents any such catastrophe, and
when the machine is turned to chop the cot-
ton on any trip through the field the track atthe off side of the rows of hills will form a
guide for the wheel at the near side of the
machine, insuring a proper distance between 70
the hills.
By reason of the disks being set in pairs,
as above described, and followed by plows of
suitable size and shape the dirt is first thrown
from the cotton by the disks, forming a ridge 75
between each pair of disks. The plows fol-
lowing the disks open and spread these ridges
and thus thoroughly cultivate across all the
land except the narrow strip left between the
convexed faces of the disks where the cotton 8o
is to be left standing, enabling the operator
to cultivate every portion of his field in a
most thorough manner, the standing cotton
being well supplied with loose dirt, and the
use of the hoe is obviated except where it is 85
necessary to remove surplus stalks from the
hills, which can be done at any subsequent
time that may be deemed best.
The horses are so attached to the machine
that they will travel in front of the space be- 90
tween the concaved faces of the outer disks,
and therefore will not trample down any of
the plants that should be left standing.
It is obvious that the plows and choppers
may be made to enter the ground as far as 95
desired or may be entirely removed from the
ground through the medium of the levers 17.
I desire it to be understood that single
hangers 19 may be adjustably placed upon
the supporting-bar 15 for each disk chopper 00o
of all the pairs of choppers, in order that the
width of the hills of cotton may be regulated
by moving both hangers of all the pairs of
choppers closer together or wider apart, as
desired, thus obviating the necessity of a o05
lengthened spindle upon which any disk chop-
per is to revolve. While the means shown
for adjusting the ground-wheels upon the
axle is in many instances desirable the ad-
justment of the wheels may be accomplished iio
by employing any adjustable axle in common
use.
It is obvious from the above description of
the invention that the device is susceptible
of some modification without material depar- 1 15
ture from the principle and spirit of the in-
vention, and for this reason I do not wish to
be understood as limiting myself to the pre-
cise form of the parts herein set forth.
Having thus described my invention, I i20
claim as new and desire to secure by Letters
Patent-
1. In a cotton-chopper, the combination of
hangers comprising two parallel bars, concave
rotary disks pivoted thereto on each side of 125
the center, with a plow-beam passing between
said bars and guided thereby and a shovel
upon its rear end occupying the space between
said disks, substantially as described.
2. In a support for rotary disks the combi- 130
nation of a depending arm having a horizon-
tal head extending across the line of motion,
and provided with vertical holes therethrough
near each end and locking pin-holes adjacent
