JOHN J. BALLARD, OF TERRELL, TEXAS.
COTTON-CHOPPER.
SPECIFICATION forming part of Letters Patent No. 372,008, dated October 25, 1887.
Application filed March 10, 1887. Serial No. 230,443. (No modell)To all whon it 7C coacernr:
Be it known that I, JonN J. BALLA D, a
citizen of the United States, residing at Ter-
rell, in the county of Kaufman and State of
5 Texas, have invented a new and useful Im-
provement in Cotton-Choppers, of which the
following is a specification.
3My invention relates to an improvement in
cotton choppers; and it consists in the pecu-
io liar construction and combination of devices,
that will be more fully set forth hereinafter,
and particularly pointed out in the claims.
In the drawings, Figurel is aside elevation
of the cotton-chopper embodying my improve-
15 meuts, parts of the frame being broken away
to disclose interior constructions. Fig. 2 is a
top plan view of the same. Figs 3 and 4 are
detailed views.
The frame is composed of a pair of parallel
20 side bars, A, connected together at their front
ends by a block, B, and at the rear ends by a
transverse bar, C.
D represents the handles, which are similar
to plow-handles, and have their lower ends
25 bolted to the outer sides of the side bars. The
said handles are connected together by means
of a rung, E, and are connected to the side
bars by means of vertical standards F.
G represents a clevis, which is attached to
30 the block B1 by means of a pivotal bolt, H.
I represents a transverse driving-shaft, which
is journaled in suitable bearing-blocks secured
on the under sides of the sidebars, A, at a suit-
able distance from the front end of the frame.
35 The ends of this shaft project beyond the outer
sides of the side bars, and to the said project-
ing ends of the shaft is rigidly attached a pair
of driving and supporting wheels, K.
L represents a miter gear-wheel, which is
40 rigidly secured to the shaft I at a suitable dis-
tance to one side of the center thereof.
M represents a longitudinal shaft, which is
journaled in blocks N, that connect the bars
A on the under sides thereof. The front end
45 of the shaft is provided with a rigid miter-
pinion, O, that meshes with the gear-wheel L.
The shaft M is made in two sections connected
together by a collar, P, which is rigid to the
front section and forms a bearing for the front
50 end of the rear section. On the latter is
feathered a sliding collar, I, forming a clutch,which is adapted to engage the collar P when
moved forward, and thereby lock the two sec-
tions of the shaft M rigidly together, for the
purpose to be hereinafter described. To the 55
rear end of the shaft M is rigidly attached a
a miter gear-wheel, S.
T represents a short vertical shaft, which is
journaled in bearing-boxes U, that connect the
bars A, and are arranged on the upper and 6o
lower sides of the said bars. Near the upper
end of this shaft is a miter-pinion, V, which
engages the gear-wheel S, and to the lower
end of the said shaft is attached a circular
plate, W. This plate is provided with aseries 65
of radial grooves, W', and in the center of each
groove is a radial longitudinal slot, W'. The
grooves WV' are formed on the upper side of
the plate T, and the slots communicate with
the said grooves and-extend entirely through 70
the said plate.
X represents a series of supporting- feet, each
of which has its upper end bent at right angles
to form an arm, X', adapted to fit in one of the
grooves of the plate. A clamping-bolt, XZ, is 75
provided for each of the said arms, the said
clamping - bolts being adapted to extend
through the slots W2, and thereby secure the
arms to the plate. -By reason of the slots W,
the arms may be moved outwardly from the 80o
center of the plate to any desired distance. To
the lower end of each supporting-foot is se-
cured a hoe or chopper, Y, the said hoes or
choppers having two straight cutting-edges
arranged at a suitable angle, and being flat on 85
their lower sides and angular on their upper
sides, as shown, thereby forming inclines Y',
which extend from the center of the hoes to
the cutting-edges thereof.
Z represents a pair of vertical cutters, which 90
are bolted to the outer sides of the side bars,
A, and are provided at their upper ends with
a series of openings, Z', whereby they may be
vertically adj usted on the bolts and thus caused
to run at any desired depth in the ground. 95
The opposing inner sides of the cutters are
curved, as shown at Fig. 2, and the lower edges
of the cutters are rounded, as shown at Fig. 1.
Draft-rods A' are attached at their rear ends
to the cutters, and have their front ends con- too
nected to the side bars by means of bolts B',
which extend through slots C', formed in the
