JOHN M. ROBINSON, OF GOLDTH.WAITE, TEXAS.
WEED-CUTTING ATTACHMENT FOR PLOWS.
SPECIFICATION forming mart of Letters Patent No. 707,801, dated August 26, 1902.
Application filed May 29, 1902, Serial No,109,467. (No modeL)To all witoim it m ay COnCern1:
Be it known that I, JOHN M. ROBINSON, a
citizen of the United States, residing at Gold-
thwaite, in the county of Mills and State of
5 Texas, have invented certain new and useful
Improvements in Weed-Cutting Attachments
for Plows; and I do declare the following to be
a full, clear, and exact description of the in-
vention, such as will enable others skilled in
to the art to which it appertains to make and use
the same.
The invention relates to weed-cutting de-
vices for plows, and has for its object to pro-
vide the shovel of a plow or cultivator with
15 blades or knives which are adapted to enter
the soil a slight distance and cut down or up-
root all weeds or grass and at the same time
to smooth and pulverize the soil.
A further object is to provide a device of
20 the character described which shall be sim-
ple and inexpensive of construction, strong
and durable in use, and well adapted for the
use to which it is designed, and which maybe
readily applied to plows or cultivators now in
25 use.
With these and other objects in-view the
invention consists of certain novel features
of construction, combination, and arrange-
ment of parts, which will be hereinafter more
30 fully described and particularly pointed out
in the appended claims.
In the accompanying drawings, Figure l'is
a perspective view of a portion of a plow,
showing the application of my device. Fig.
35 2 is a detail perspective view of one of the
blades detached. Fig. 3 is a similar view of
one of the brace-rods; and Fig. 4 is a rear view
of the shovel, showing the manner of attach-
ing the blades.
4o Referring to the drawings, 1 denotes the
shovel of an ordinary plow or cultivator, which
is secured to the beam by a bolt a, passing
through the elongated aperture b.
2 denotes the blades or knives, which con-
45 sist of narrow flat bars of steel, the inner
ends 3 of which are bent or twisted at an an-
gle to the blade and bolted to the back side
of the plow-shovel near the upper edge of the
same.4 denotes brace-rods connected at their 50
outer ends to the free ends of the cutting-
blades and at their inner ends to the plow-
shovel.
It will be noticed that the manner in which
the cutting-blades are bent at the point of 55
their connection with the shovel gives the
said blades the proper pitch or inclination to
enter the ground to the proper depth and cut
the weeds at their roots or entirely uproot
the same and cultivate the soil on both sides 6o
of the plow-shovel.
From the foregoing description, taken in
connection with the accompanying drawings,
the construction, mode of operation, and ad-
vantages of the invention will be readily un- 65
derstood without requiring an extended ex-
planation.
Various changes in the form, proportion,
and details . of construction may be made
within the scope of the invention without de- 70
parting from the spirit or sacrificing any of
the advantages thereof.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is- 75
1. In a cutting attachment for plows, the
combination of the plow-shovel, the cutting-
blades attached to the shovel, and brace-rods
connecting the outer ends of said blades with
said shovel, substantially as set forth. 8o
2. In a weed-cutting attachment for plows
and cultivators, the combination of the plow-
shovel, the cutting - blades attached to the
shovel and having their attaching ends bent
and twisted at an angle to said blades so that 85
when bolted to said shovel the blades will lie
at the proper cutting angle, and brace-rods
connecting the outer ends of said blades to
the plow-shovel, substantially as set forth.
In testimony whereof. I have hereunto set 90
my hand in presence of two subscribing wit-
nesses.
JOHN- M. ROBINSON.
