JAMES:POWELL OWENS, OF WEATHERFOID, TEXAS.
-_IIIit QWA~ .Specification of Letters.Patent.
Patented July 29,191',
Application filed- August 2Q, 1912; Serial No. 716,094;
To all whom it may concern:
Be it known that I, JAMEs P. OwENs, a
citizen of the United States, residing at
Weatherford, in the county of Parker and
5 State of Texas, have invented a new and
useful Harrow, of which the following is a
specification.
This invention relates to agricultural ap-
pliances and more particularly to improved
10 means whereby the roots of small vegetable
growths, such as weeds, grass, cotton plants
and the like may be cut off elose to but below
the surface of the ground, the cutting means
being simple, durable and inexpensive and
15 offering the minimum resistance to the op-
eration of the appliance so that a large ma-
chine can be actuated with comparatively
slight power.
With. the. foregoing and other objects in
20 view which will appear as the description
proceeds, the invention resides in the com-
bination and arrangement of parts agd in
the details of construction hereinafter de-
scribed and claimed, it being understood
25 that changes in the precise embodiment of
the invention herein disclosed, can be made
within the scope of what is claimed, without
departing from the spirit of the invention.
In the accompanying drawings the pre-
30 ferred form; of the invention, as embodied
in a. cotton chopper, has been shown.
In said drawings :-Figure.1 is a rear ele-
vation of a cotton chopperL showing the im-
proved means .for cutting.the roots of plants.
35 Fig. 2 is aside elevatioli of the cotton chop-
per. Figs..3 and-4 are perspective views of
the spreading means utilized. Fig. 5 is a
rear elevation. of a. slightly modified struc-
ture. Fig. 6 is a transverse section through
40 a modified form. of cutting element.
Referring to the figures by chaiaters of
reference 1 designates a..structur:e made up
of any desired arrangement of beams suit-
ably connected and from which extend han-
45 dles 2. This structure includes a rear cross
beam 3 and secured to this cross beam in any
suitable manner are downwardly extending
spring teeth 4 adjustable relative to each
other and each preferably including, at an
50 intermediate point, an eye 5. The lower
end of each tooth is broadened from front
to rear, as shown at 6 and has a downwardly
extending toe 7.
In the form of the invention illustrated in
56 Figs. 1 and 2, the teeth 4 are arranged in
two end pairs while interposed betweenthese pairs is a group of three teeth. The
teeth of each pair are connected by a small
but strong wire 8 of steel or any other suit-
able material, the ends of the wie being 60
wrapped about and securely fastened to toes
7 of the teeth. A spreading strip 9 is inter-
posed between the teeth and has notches 10
in its ends to .receive portions of the teeth.
This spreading strip is slightly longer, than 65
the distance between the lower ends of the
teeth so that, when the strip is interposed
between the teeth close to the eyes 5, it will
spring the teeth laterally and cause them to
pull on the wire 8 and thus hold it taut. 70
The central group of teeth 4 is provided
with a wire 11 similar to the wire 8 but
which is wrapped. about and suitably se-
cured to the toes 7 of the three teeth consti-
tuting said group. A spreading strip 12 is .5
interposed between the side teeth of. the
group and has notches 13 in its ends for re-
ceiving portions of said teeth. Another
notch 14. extends into one edge of the strip
12 adjacent its center and is adapted to re- so
ceive a portion of the middle tooth of the
group, Thus it will be seen that when the
strip 12 is in place, it will bow the end teeth
of the group laterally and cause them to
hold the wire 11 taut under all conditions. 85
By arranging the teeth in groups as shown,
clear spaces. are provided between the
groups, as shown at 15. Any suitable ar-
rangement of braces 16 may be extended for-
wardly from the teeth 4;. certain of these go
braces being preferably attached to the eyes
5 of the teeth.
It is to be understood that when the de-
vice herein described is to be used for cut-
ting out cotton plants, it is to be drawn 95
transversely of the rows of plants and the
broad lower ends of.' the teeth 4 will plow
into the soil so as to support the wires 8
and 11 below but close to the surface of the
soil. Thus, as the appliance is drawn trans- 100
versely of the rows, the wires 8 and 11 which
are held taut, will cut through the roots of
the vegetable growths in the paths thereof
and only those plants in line with the spaces
15 will remain standing. Thus, by adjust- 105
ing the teeth 4 toward or from each other
the distances between the spaces can be
varied at will and the size of said spaces can
be controlled. Also, if desired, any other
suitable groupings of teeth can be employed, 110
it merely being necessary, in every instance
to have the wires strung taut at the points1,068,526.
