JOHN R. MILLER, OF BEND, TEXAS.
COTTON-CHOPPER.
SPECIFICATION forming part of Letters Patent No. 576,877, dated February 9, 1897.
Application filed September 9, 1896, 'Serial No, 605,264, (No model,)To all whom, it m71ay concern:
Be it known that I, JOHN RICKMAN MILLER,
of Bend, in the county of San Saba and State
of Texas, have invented a new and Improved
5 Cotton-Chopper, of which the following is a
full, clear, and exact description.
The object of my invention is to construct
a cotton-chopper whereby the choppers will
be adjustable, so as to regulate the distance
to between the hills of cotton, and to provide
cultivators arranged to follow the choppers
in such manner that the space between the
rows of hills will be cultivated as the hills are
formed.
15 A further object of the invention is to pro-
vide a means whereby the ground or support-
ing wheels will be adjustably placed upon
their axles, so that they may be adjusted cor-
respondingly to the adjustment of the chop-
20 pers, to insure a uniform distance between
the rows of hills as the machine is drawn up
and down the field.
A further object of the invention is to con-
struct a cotton-chopping machine which will
25 be simple, durable, and economic, yet exceed-
ingly strong and effective in its operation.
The invention consists in the novel con-
struction and combination of the several
parts, as will be hereinafter fully set forth,
30 and pointed out in the claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar characters of reference indi-
cate corresponding parts in all the figures.
35 Figure 1 is a plan view of the improved ma-
chine. Fig. 2 is a longitudinal section taken
through the machine at one side of the pole.
Fig. 3 is a detail plan view of a hanger and a
disk chopper adjustably connected therewith,
40 a portion of the hanger being in section; and
Fig. 4 is a vertical section through a portion
of the hanger shown in Fig. 3, illustrating a
disk chopper in section and the spindle sup-
porting the chopper partly in side elevation
45 and partly in section.
In carrying out the invention the tongue or
pole of the machine is attached securely to an
arched axle 11, and the spindles 12 of this
axle are of greater length than the ordinary
50 spindles and are provided with series of aper-
tures 13, arranged at such distances apart
that the hubs of the supporting-wheels 14,adapted to turn on the axles, may be brought
between any two of the apertures on the spin-
dles. A cross-bar 15 is supported in front of 55
the axle, preferably through the medium of
links 16, which are attached to the said bar
at each side of its center, and each of the said
links slide loosely through an adjusting-le-
ver 17, placed convenient to the driver's seat 6o
17a. These levers are provided with the usual
thumb-latch for engagement with racks 18,
which are attached,usually, to the rear branch
portions of the pole 10 and to the axle 11, since
the rear portion of the pole 10 is bifurcated, as 65
shown in Fig. 1. Each link is passed through
a coiled spring 16", and said springs have
bearings against the foot portions of the lever
and against the bar 15 or other support.
Hangers 19 are adjustably carried by the 70
cross-bar 15, and are secured on the said bar
through the medium of set-screws 20 or their
equivalents. Each hanger 19 comprises a
vertical shank member a and a horizontal
foot member cc', which is at the rear of the 75
shank member and is much wider than the
said shank member, as shown particularly in
Fig. 3. The shank member of each hanger
has an opening 21 made horizontally therein,
and a plow - stock 22 is carried rearwardly 80
through the opening 21 of each hanger, and
these plow-stocks extend beyond the rear of
the hangers, their forward ends being made
to converge beneath the pole and are pivoted
to and have lateral movement upon a bolt 23, 85
placedin a yoke 24, secured to the under face
of the pole.
The horizontal or foot member of each
hanger is provided with an opening 25 near
each of its ends, extending through from top 90
to bottom, and a similar opening 26 adjacent
to each of the larger openings 25. The foot-
section of each hanger is adapted to carry
two angular spindles 27, embracing a ver-
tical member b, which is passed up loosely 95
through an opening 25 in the foot member of
the hanger, and a horizontal section b', which
is provided with a series of apertures 28. At
the upper end of the vertical member b of a
spindle 27 a wheel or a disk 29 is securely fas- 00oo
tened, the said wheel or disk being just above
the upper face of the foot-section of the
hanger, and the said wheel or disk has a num-
ber of cavities 30 produced in its periphery,
