UNITED STATES PATENT OFFICE,
COLUMBUS SCOTT MAULDIN, OF HIINCKLEY, TEXAS.
STALK-CHOPPER AND COTTON-THINNER.
SPECIFICATION forming part of Letters Patent No. 459,640, dated September 15, 1891.
Application filed April 29, 1891, Serial No. 890,956. (No model.)To all whom it 7iay concern':
Be it known that I, COLUMBUS SCOTT MAUL-
DIN, a citizen of the United States, and a resi-
dent of Hinckley, in the county of Hunt and
5 State of Texas, have invented certain new and
useful Improvements in Stalk-Cutters and
Cotton-Thinners; and I do hereby declare that
the following is a full, clear, and exact de-
scription of the invention, which will enable
io others skilled in the art to which it appertains
to make and use the same, reference being
had to the accompanying drawings, which
form a part of this specification.
My invention relates to improvements in
15 cotton choppers and thinners, the object be-
ing to provide a simple and economical con-
struction of apparatus in which certain of
the parts are made removable and replace-
able, so as to use the apparatus either as a
zo20 stalk-chopper or a cotton-thinner, or may be
changed to a dropper, as may be desired.
The invention consists in the novel con-
struction and combination of parts herein-
after fully described, and specifically pointed
25 out in the claim.
In the accompanying drawings, Figure 1 is
side elevation of an apparatus constructed in
accordance with my invention. Fig. 2 is a
central longitudinal section of the same. Fig.
30 3 is a plan view.
In the said drawings the working parts are
supported by a rectangular frame consisting
of the side pieces 1 and front and rear cross-
bars 2. To the front cross-bar is secured the
35 tongue 3, having a whiffletree 4.
Journaled in the side bars 1 is a shaft 5,
which carries a drum 7, consisting of end
disks 8 and one or more intermediate disks
9. These disks are connected by means of
40 transverse staves or bars 10, removably se-
cured to the peripheries of said disks, with
a series of spaces 12 between said staves.
Secured to one or more of these staves is a
series of brackets 13, having apertures in
45 their ends which register with correspond-
ing apertures in knives or cutters 14, which
are embraced between said brackets and re-
movably secured thereto by means of set-
screws 15. The shaft 5, intermediate of itsends, is made square or angular and passes 50
through corresponding apertures in the disks,
so that said disks and shaft will rotate to-
gether. The outer ends of the shaft are
made cylindrical, forming spindles to receive
wheels 16, which may be of any ordinary con- 55
struction. In rear of the drums is a trans-
verse scraper-blade 17, secured to the side
bars and serves the purpose of cleaning the
drum of any dirt which might otherwise ac-
cumulate thereon. 6o
The numeral 18 designates uprights se-
cured to the side bars, connected at their up-
per ends by means of a transverse board or
plank 20, which serves as a seat for the driver.
These uprights are braced by means of di- 65
agonal bars 21, secured to the front and rear
of the side bars 1.
The operation is as follows: When used as
a cotton-stalk chopper, the machine is drawn
over the field, when the drum will be rotated 70
and the cutting-blades will engage with and
cut the stalks. To use the machine as athin-
ner, the wheels and blades are removed, so
that the drum will rest directly upon the
ground, acting as a roller, the staves or solid 75
portions thereof crushing out the growing'
plants in the rows, the plants which it is de-
sired to leave standing projecting up in the
spaces between the staves, so that the roller
will pass over the same without injuring them. 8o
The roller or drum also packs the ground
around the stand and crushes and pulverizes
the clods. The staves are made removable,
so that the size of the spaces and the distance
apart can be regulated as circumstances may 85
require. By means of holes around the drum
and near each end the operation of dropping
is carried on, two plows being attached to a
cross-bar just in front of the drum for the
purpose of laying off the ground; also, four 90o
plows are attached to a cross-bar just be-
hind the drum for the purpose of covering
the seed.
Having thus described my invention, what
I claim is- 95
The herein-described cotton chopper and
thinner, comprising the rectangular frame,
the tongue, the shaft journaled in the frame,
