JC. CHRISTON GUNN, OF WALNUT SPRINGS, TEXAS.
COTTON-CHOPPER.Specification of Letters Patent. Patented Apr. 24, 1917.
Application filed December 7, 1916. Serial No. 135,637.To all wkom it may concern:
Be it known that I, JC. CHRISTON GrUNN,
a citizen of the United States, residing at
Walnut Springs, in the county of Bosque,
5 State of Texas, have invented new and use-
ful Cotton-Choppers; and I do hereby de-
clare the following to be a full, clear, and
exact description of the invention, such as
will enable others skilled in the art to which
10 it appertains to make and use the same.
The present invention relates to certain
new and useful improvements in the con-
struction of machines for thinning young
plants, such machines being more commonly
15 employed in the cultivation of cotton, and
being popularly termed cotton choppers, the
object of the invention being to provide a
machine of this character which embodies
novel features of construction whereby it
20 can be utilized in connection with a culti-
vator for simultaneously thinning and cul-
tivating young cotton plants.
Further objects of the invention are to
provide a machine for thinning young
25 plants which is comparatively simple and
inexpensive in its construction, which can be
attached to and used in connection with
practically any of the conventional forms of
wheel cultivators, which can be adjusted to
30 increase or decrease the distances between
the stands of young plants, and which oper-
ates in an effective manner to prevent the
young plants which are left standing from
being covered with dirt from the cultivator
35 shovels.
With these and other objects in view, the
invention consists in certain novel combi-
nations and arrangements of the parts as
will more fully appear as the description
40 proceeds, the novel features thereof being
pointed out in the appended claims.
For a full understanding of the invention,
reference is to be had to the following de-
scription and accompanying drawing, in
45 which:-
Figure 1 is a longitudinal sectional view
through a cultivator which is provided with
a cotton thinning device constructed in ac-
cordance with the invention.
50 Fig. 2 is an enlarged side elevation of the
cotton thinning device, portions being
broken away and shown in section to illus-
trate more clearly certain details of con-
struction.
55 Fig. 3 is a top plan view of the cotton
thinning device.Fig. 4 is a detail view of one end of the
cross bar to which the cotton thinning de-
vice is attached.
Corresponding and like parts are referred 60
to in the following description and indi-
cated in all the views of the drawings by
the same reference characters.
For the purpose of illustration the inven-
tion is shown as employed in connection 65
with a conventional form of wheeled culti-
vator, including a main frame 1 and wheels
2 which are mounted upon an axle 3. A
trailing cultivator beam 4 is arranged upon
each side of the machine, said beams car- 70
rying the conventional cultivator shovels 5
and having the forward ends thereof pivot-
ally connected at 6 to the main frame 1. A
seat 7 is provided for the operator, and
hand levers 8 which are mounted adjacent 75
to the seat 7 are operatively connected to the
cultivator beams for the purpose of raising
and lowering the same. This may be done
in any conventional manner, although in
the present instance forwardly extending 80
links 9 connect the hand levers to bell cranks
10 which are in turn connected by down-
wardly extending links 11 to the cultivator
beams 4. If desired, spring plungers 12
may act upon the cultivator beams to hold 85
the cultivator shovels to their work. This
is all of the conventional and well-known
construction, and no claim to novelty is
based thereon.
The plant thinning mechanism includes 90
a forward drum A provided with peripheral
plant receiving pockets 13, and a rear wheel
B provided with correspondingly arranged
plant receiving cups 14, the drum and wheel
being mounted to move in synchronism so 95
that the cups 14 will cover the young plants
which are left standing by the pockets 13 of
the drum A, the intervening plants being
crushed by the portions of the periphery of
the drum between the pockets 13. On the 100
drawings the drum A and wheel B are
shown as mounted upon the respective trans-
verse shafts 15 and 16 which connect the
side pieces of a frame 17, sprocket wheels
18 being rigidly fitted upon the respective 105
shafts and connected by a chain 19 to insure
that the drum and wheel will move in syn-
chronism.
The forward end of the frame 17 is pivot-
ally connected at 20 to a pair of arms 21 110
which project downwardly from a cross bar
22, the extremities of the cross bar having1,223,868.
