WALLIE It. BOONE, OF WHITEFLAT, TEXAS.
AGRICULTURAL IMPLEMENT'.Specification of Letters Patent. Patented Sept. 23, 1919.
Application filed December 14, 1918. Serial No. 266,740.To all whom it may concern:
Be it known that I, WALLIE R. BooNE, a
citizen of the United States, residing at
Whiteflat, in the county of Motley and State
5 of Texas, have invented certain new and
useful Improvements in Agricultural Im-
plements; and I do hereby declare the fol-
lowing to be a full, clear, and exact descrip-
tion of the invention, such as will enable
10 others skilled in the art to which it apper-
tains to make and use the same.
This invention relates to agricultural im-
plements, and more particularly to an imple-
ment for destroying weeds and other noxious
15 'plants by cutting the same.
One of the main objects of the invention is
to provide an implement of the character
stated of simple construction and operation
employing spaced supporting runners adapt-
20 ed to pass on opposite sides of a row of
plants, these runners being provided with
outwardly projecting cutting members for
cutting the weeds between adjacent rows of
plants.
25 A further object is to provide simple and
efficient means whereby the cutting knives
may be readily adjusted so as to vary their
effective cutting width to accommodate
variations in the distance between rows of
30 plants.
A further object is to provide simple and
efficient adjusting means for the cutting
knives which may be readily applied to an
implement of this type, commonly known
35 as "go-devils," without necessitating any
material changes in the construction of the
implement itself.
Further objects will appear from the de-
tailed description.
40 In the drawings:
Figure' 1 is a top plan view of a go-devil
with knife adjusting means constructed in
accordance with my invention applied.
Fig. 2 is a side view.
45 Fig. 3 is a" section taken substantially on
line 3-3 of Fig. 2.
Fig. 4 is a detail plan view of the casting
for supporting the knife and the setting
screw therefor.
so Fig. 5 is a transverse sectional view
through one of the cutting knives.
The frame of the implement comprises
twso spaced runners 1 which are held in
spaced relation and in parallelism by a con-
55 nesting bow 2 secured thereto. Each of
these runners is provided at its forward endwith a clevis 3 by means of which traction
attaching means may be readily secured to
the runners for pulling the same along a
row of plants, one runner being positioned 60
at each side of the row and closely adjacent
thereto. This implement constructed in this
manner is well known and forms no part of
my invention, except in so far as it cooper-
ates with the means to be described of ac- 65
complishing the desired results.
A supporting member or casting desig-
nated generally by 4 is secured to the outer
face of each runner 1, this casting being pro-
vided with a lateral flange 5 through which 70
are inserted securing screws 6 threaded into.
the body of the runner. The casting is fur-
ther provided with a central U-shaped socket
7 which receives a corresponding rib 8 pro-
vided on the lower edge portion of the run- 75
ner, and a metallic strip 'or shoe 9 is secured
to the lower edge of the runner, as shown.
A cutting knife designated generally by
10 has its inner end portion reduced and
shaped to provide a substantially semi-ellip- 80
tical element 11 which is provided with a
central opening which receives the lower end
portion of a securing bolt 12 'inserted
through runner 1 and socket member 7 of
the casting 4, this bolt being passed through 85
element 11 of the knife and screwed into
shoe 9 of the runner which is provided with
a threaded opening for this purpose. in
this manner, the knife is secured to the run-
ner so as to be rockable about a vertical axis, 90
this knife projecting laterally of the run-
ner so as to engage weeds and noxious plants
positioned to one side of the row of plants
along which the implement is drawn. As
will be noted more clearly from Fig. 4, cast- 95
ing 4 is provided on its outer face with an
angularly disposed lug 13 which is bored
and threaded to receive a set screw 14. This
lug is positioned so that the set screw may be
turned into engagement with the element 11 100
of the knife inside of the axis of bolt 12 so
as to adjust this knife about the bolt and
vary its angle to the runner. By turning
the set screw inwardly, the outer end of the
knife will be moved in an are in such direc- 105
tion as to bring the knife into a position sub-
stantially at a right angle to the runner.
When in this position, the knife will cut
weeds and noxious plants over a relatively
wide strip or space as the implement is 110
drawn along the row of plants. By varying
the adjustment of the knife, the width of the1,316,676.
