JOSEPH W. MARTIN, OF ABILENE, TEXAS.
COTTON-CHOPPER.Specification of Letters Patent.-
Patented Mar. 8, 1910.
Application filed Jaly 19, 1909. Serial No. 508,351.
To all whom it may concern:
Be it known that I, JOsEPH W. MARTIN,
a citizen of the United States, residing at
Abilene, in the county of Taylor and State
5 of Texas, have invented certain new and
useful Improvements in Cotton-Choppers,
of which the following is a specification.
My invention relates to new and useful
improvements in cotton choppers, and more
10 particularly to that class of choppers, which
are adapted to operate upon two cotton rows
simultaneously. Its object is primarily to
provide a cotton chopper which will mechan-
ically perform the operation of " blocking
15 out" or chopping rows of cotton into series
of equi-distant hills, at a rate of speed that
will produce an economy of time and labor
over the manual performance of this oper-
ation.
20 Another object is to provide a cotton
chopper having double sets of hoes, rotating
transversely of the machine, and capable of
adjustment both vertically and laterally,
thus allowing the depth of the stroke and
25 the distance between the hoe shafts to be
regulated.
A further object lies in the provision of a
two-row cotton chopper, having resilient
supports for the hoe shafts, thus permitting
30 the hoes to be momentarily displaced from
their normal path of rotation, on striking an
unyielding obstacle, and so preventing
breakage of hoe blades.
Finally, the object of my invention is to
35 provide a device of the character described,
that will be strong durable, simple and ef-
ficient, and comparatively easy to produce,
also one in which the various parts will not
be likely to get out of working order.
40 With these and various other objects in
view, my invention has relation to certain
novel features of construction and oper-
ation, an example of which is described in
the following specification, and illustrated
45 in the accompanying drawings, wherein:
Figure 1. is a top view of the cotton
chopper complete with the exception that
the upper portion of the lifting lever cen-
trally mounted on the frame is broken away
50 to show the construction therebeneath. Fig.
2. is a side elevation of the same. Fig. 3.
is a rear view of the machine, a portion of
the rear axle being broken away at the left
side thereof, to make clear the manner of
3 securing transverse adjustment of the rear
extremity of the hoe shafts; the gearingcommunicating rotation to the left hoe shaft
is also omitted in this view. Fig. 4. is a
front view of a portion of the machine
showing the construction adapting the for- 60
ward extremities of the hoes to be raised
and the manner of pivoting the frame on
the forward axle. Fig. 5. is a detailed side
view of the extremity of a rod having a
curved arm attached thereto, the purposes 65
of which are made clear hereafter.
Referring now more particularly to the
drawings, wherein like numerals of refer-
ence designate similar parts in all the fig-
ures, the numeral 1, denotes the forward axle 70
of the machine, and 2, the rear axle, the
beams 3, of irregular shape, extending be-
tween the two. and being supported thereby.
The forward extremities of the two outer
beams 3 rest upon a cross bar 4 pivoted upon 75
the axle, the middle beam 3 being extended
through a slot 5 in the axle and retained by
the pivot bolt 6. The rear extremities of
the two outer beams 3 rest upon the bar 7,
which is bolted to the axle 2, and the middle 80
beam is extended into a slot 8 between the
bar 7 and the axle and there secured.
The transporting wheels. are transversely
adjustable upon both axles, set collars -9 be-
ing mounted thereupon at the inside of 85
each wheel, and a plurality of holes 10 be-
ing provided in the extremities of the axle,
adapted to receive pins, preventing outward
displacement of the wheels.
Each of the rear wheels has rigidly at- 90
tached to its inner side, a beveled gear 11,
meshing with a beveled pinion 12, fast upon
the rear extremity of a hoe shaft 13. These
shafts are rendered flexible by the universal
joints 14 therein. The rear extremities of 95
the shafts 13 pass through transverse aper-
tures in the circular rods 15, and are rota-
table therein. The rods 15 are slidably
mounted in the extremities of a cross bar 16,
which is transversely supported upon the 100
beams 3.
Curved, segmental racks 17 are mounted
upon the cross bar 16 at each side thereof, and
levers 18 are pivoted from the centers of the
racks, being adapted to swing transversely 105
of the machine, and having the usual spring-
pressed rods acting in conjunction with the
racks to hold the levers in adjustment. . A
pair of rigid, swinging links 19 extend from
each lever 18 to the adjacent hoe shaft and 110
are attached thereto at either side of the cross
bar 16. Obviously, by manipulating the levers951,405.
