DRURY P. SHAW, OF RHOME, TEXAS, ASSIGNOR OF ONE-HALF TO W. J. TACKABERRY, OF
FORT WORTH, TEXAS.
STALK-BREAKER.Specification of Letters Patent.
Patented Oct. 27, 1908.
Application filed February 19, 1908. Serial No. 416,722.
To all whom it may concern:
Be it known that I, Dnun P. SHAW, a citi-
zen of the United States, residing at Rhome,
county of Wise, and State of Texas, have in-
- vented certain new and useful Improvements
in Stalk-Breakers, of which the following is
a specification.
My invention relates to improvements in
devices for breaking such stalks as cotton
10 stalks, and the object is to provide simple
devices which may be attached to a suitable
vehicle. I have provided a stalk breaker
which may be attached to a cultivator frame.
Another object is to provide an adjusting
15 means which will adapt the stalk breaker to
break the stalks out of young wheat, or
growing wheat plants without breaking the
young plants.
Other objects and advantages will-be fully
20 explained in the following description and
the invention will be more particularly
pointed out in the claims.
Reference is had to the accompanying
drawings which form a part of.this applica-
25 tion and specification.
Figure 1 is a side elevation of a stalk
breaker, the reel of which is slightly broken
away. Fig. 2 is a plan view of the same.
Fig. 3 is vertical section of one of the reel
30 supporting arms, taken along the line x x of
Fig. 1. Fig. 4 is a detail view of one of the
reel supporting arms, showing the manner of
adjusting the hanging blade.
Similar characters of reference are used to
35 indicate the same parts throughout the sev-
eral views.
A cultivator and the wheels thereof are
used for operating my improved stalk
breaker. The wheels 1 and 2 support an
40 axle 3 of the ordinary type for cultivators.
The backwardly projecting beams 4 and 5
are utilized for mounting the reel. The reel
is composed of the hub 6,. circular frame
pieces 7, blades 8 which are carried by the
45 arms 9 which are attached to the hubs 6.
The reel is mounted on a shaft 10 which is
journaled in the reel carrying arms 11 and
12. The arms 11 and 12 are pivotally con-
nected with the beams 4 and 5 by means of
50 the upwardly projecting ears 13 of clamps 14
which are clamped on beams 4 and 5. The
reel carrying arms are provided with guides
15 which are rigidly mounted on the ends of
the beams 4 and 5. The guides 15 are pro-
55 vided with a number of perforations andsupporting pins 16 are used to hold the arms
11 and 12 at the proper height. The arms
11 and 12 rest on the pins 16, but are free to
rise up or yield upwards for the purpose here-
inafter explained. The reels are driven by 60
sprocket wheels 17 which are mounted on
the wheels 1 and 2 and wheels 18 which are
mounted on the reel shaft 10 and the
sprocket-chains 19 which transmit the power
from wheels 1 and 2 to wheels 18. 65
A breaking bar or blade 20 is hung on the
arms 11 and 12 by means of the arms 21.
The blade 20 is mounted just below the beat
of the blades 8 and serves as a means against
which the blades 8 break the stalks. The 70
arms 21 are made adjustable on the reel car-
rying arms 11 and 12 so that the blade 20
may be raised or lowered, the arms 21 having
slots 22 for this purpose. The object of this
adjustment is to make the distance between 75
the blade 20 and the blades 8 as they pass
blade 20 greater where the machine is used
to break cotton stalks standing among young
wheat plants so that the wheat plants will
not be cut or broken by the blades. The 80
blade 20 is held rigid by the braces 23 which
are attached to the arms 21 and to the reel
carrying arms 11 and 12. The blade 20 will
thus rise with the arms 11 and 12. The
blade 20 is set at angle so that the blade 85
will rise up and pass over all ordinary ob-
structions, the pivoted reel carrying arms
permitting this upward movement.
The slack of the chains 19 is taken up by a
lever 24 which is fulcrumed on the bar or 90
beam 4. A rack 25 of the ordinary type is
mounted on the beam 4 for holding the lever
24 at any suitable adjustment. The lever 24
is connected to the axle 3 by means of a
link rod 26. The axle 3 is bent down at each 95
end before entering the wheels 1 and 2 and
the link rod 26 is connected to the lower part
of the axle 3 so that the wheels 1 and 2 may
be thrown forward or backward by the lever
24 to regulate the tension of the chains 19. 100
The axle 3 is further braced by the link rod
27 which is connected to the arm of a rocking
beam 28.
This improved breaker may be used for
breaking old stalks out of wheat and other 105
growing plants.
Having fully described my invention, what
I claim as new and desire to secure byLetters
Patent, is,-
1. The combination of a cultivator having 110No. 902,116.
