WILLIAM THOMAS WALTER, OF ANGLETON, TEXAS.
OOTTON-CHOPPER.No. 841,289.
Specification of Letters Patent.
Application filed November 15, 1906, Serial No. 348,598.Patented Jan. 15, 1907.
To all whom it mazy concern:
Be it known that I, WILLIAM THOMAS
WALTER, a citizen of the United States,
residing at Angleton, in the county of Bra-
zoria and State of Texas, have invented a
new and useful Cotton-Chopper, of which
the following is a specification.
This invention has relation to cotton-
choppers; and it consists in the novel con-
struction and arrangement of its parts, as
hereinafter shown and described. .
The object of the invention is to provide.
a chopper of the nature indicated which may
be easily and readily adjusted for cutting
out sections of the growing plants at desired
intervals.
The chopper consists, primarily, of a wheel-
mounted frame, to which is pivotally at-
tached a chopper-frame, a ratchet-lever be-
ing located upon the wheel-mounted frame
and beingconnected with the chopper-frame
for raising and. lowering the same. The
chopper is of special construction and is
journaled to the .chopper-frame.. It com-
prises a pair of -disks provided at their pe-
ripheries with radially - extending recesses.
The en'd portions of cutting-blades are lo-
cated in said recesses, while the. extremities
of the said blades are twisted or bent at
right angles to the intemediate portions
thereof and are adapted to bear against the
outer side of the said .disks, to which sides
the extremities of the blades are bolted.
Thus a very substantial and. rigid structure
is produced' as the extremities of the blades.
are attached directly to the outer surfaces
of the disks and are seated in the peripheral
recesses of the same. The structure also.
makes it possible for each individual cotton
raiser to thin his cotton according . t ''his
a own individual taste or the condition of the
soil. This is done by removing one or nidre
of the said blades at intervals, so that the.
spaces left thereby will escape the growing
plants, while the remaining blades will de-
stroy those that they come in. contact with.
In the accompanying drawings, Figure 1 is
a side elevation of the cotton-chopper with
parts in section. Fig. 2 is a top plan'view
of the chopper-frame with the chopper in
section, and Fig. 3 is a perspective view .of
one of the chopping-blades.:
The frame of the chopper consists. of 'the
tongue 1,' to the rear portion of which is at-
tached the operator's seat 2. The side bars3 3 are attached to the tongue 1 near the rear
end of the same and are supported at their
rear ends by the upright portions 4 4 of the
axle 5. The brace-rods 6 are attached at
their forward ends to the tongue 1 and at 6o
their rear ends to the upright portions 4 of
the axle 5. . The ratchet-lever~7 is fulcrumed
to the gear-segment 8, and the rod 9 is.con-
nected at one end .to the working end of the
said lever 7~and at its other end to the cutter- 65
frame 10. The coil-spring 11 is interposed
between a guide 12, attached to the wheel-.
mounted frame of the chopper and the catter-
.frame 10.. Said spring is .under tension, the
tendency of which is to maintain the cutter- '7o
frame in the lowest possible position, and at
the same time offers a resilient resistance to
the upward movement of the last said'frame'
and its attachments with relation tothe
wheel-mounted frame. The said lever 7 and 75
its connections may be duplicated, as illus-
trated in the drawings, if desired. The cut-
'ter-frame 10 is pivoted at its forward end to
the tongue 1, and .the disks 13 are journaled
at 'the lower end of the said cutter-frame 10. 8o
The said disks 13 are foraminous, and are
thereby relieved of excessive' and .unneces-
sary weight. 'The peripheries of the disks 13
are provided with the radially-extending re-
cesses 14.: 'The cutting-blades 15 are seated 85
at points 'in.the vicinity of theirends.in said
recesses, and -the' extremities 16 of the said
blades are twisted. or bent at right angles to
the longitudinal axis -of the intermediate
portions thereof 'and bear directly against the -90
outer faces of the disks 13 and are.secured
thereto by.means of the transversely-extend=
'ing bolts 17
As above. indicated, a structure so as-
sembled- is very' rigid and is capable of with- 95
standing rough usage to, which such an im-
plement is subjected. By reason of the fact
that the. cutting-blades 15 are seated near
-their ends in. the peripheral recesses 14 of the
disks' 13 thejaid disks are positively con- oo
fined with'relation to each other, so that
they are caused to rotate in unison, and, fur-
thermore, by positively attaching the etremi-
ties of the blades.16 to the outer faces of.the
disks 13 the said, disks are confined against 1o5
lateral movement or vibration with relation
to each'-other.
As above indicated, each operator may re-
move' as many blades 15 from the disks 13 as.
condition or fancy may indicate, and' thus he 110
