JOHN L. BIRD, OF LORAINE, TEXAS, ASSIGNOR OF ONE-HALF TO ST. ELMO BROWN, OF
LORAINE, TEXAS.
STALK-CUTTER.Specification of Letters Patent.
Patented May 9, 1911.
Application filed January 13, 1911. Serial No. 602,373.
To all whom it may concern:
Be it known that I, JOHN L. BrnD, citizen
of the United States, residing at Loraine,
in the county of Mitchell and State of
5 Texas, have invented certain new and useful
Improvements in Stalk-Cutters, of which the
following is a specification.
This invention pertains to stalk cutters.
The object of the. invention is to provide
10 a stalk cutter adapted to be attached to an
ordinary cultivator or riding buster and
employing a revolving cutter drum resili-
ently supported whereby the said cutter
drum will yield upward upon encountering
15 an obstruction and save the cutters from
injury.
Finally the object of the invention is to
provide means of the character described
that will be strong, durable, efficient, and
20 easy of operation, simple and comparatively
inexpensive to construct, and also in which
the several parts will not be likely to get
out of working order.
With the above and other objects in view
25 the invention has relation to certain novel
features of construction and operation, an
example of which is described in the follow-
ing specification and illustrated in the ac-
companying drawing.
30 In the drawing I have shown a perspec-
tive view of the stalk cutter and have desig-
nated the various parts by numerals herein-
after explained.
The numeral 1 designates a pair of up-
35 wardly inclined side members converging
toward their upper ends where a pair of
transverse bars 2 and vertical bolts 3 are
employed to connect the bars and secure
them to the tongue 4 of the agricultural
40 machine. The members 1 are integral with
and extend from the forward ends of flat
horizontal side bars 5. At the intersection
of the side bars and the members 1 a trans-
verse arch 6 is secured.
45 A short distance from the rear ends of
the side bars, bearing boxes 7 are secured to
the under sides of said bars. In these boxes
the axle 8 of a drum 9 is supported. This
drum is disposed between the side bars and
50 has heads 10 adjacent said bars. Each head
has radial arms 11 to the sides of which cut-
ting blades 12 are secured so that a portion
of each blade projects beyond the outer endsof the arms. It is to be understood that
other forms of drums may be employed. 55
One of the particular features of the in-
vention is a resilient or yieldable hanger
whereby the drum is supported to yield up-
wardly when encountering stones, stumps
and other obstructions. The hanger coin- 60
prises a pair of spring arms 14 bent at sub-
stantially right angles at their forward ends
where they are provided with forwardly
directed lugs 15 secured on the side bars.
The greater portion of each arm extends 65
above and over the adjacent side bar and
normally substantially parallel thereto.
These arms are preferably of spring metal
and have their free ends terminating over
the rear ends of the side bars. Each arm 70
at its free end has a pair of spaced ears 16
between which the lower end of a link 17
is pivoted on a transverse bolt 18 passing
through the ears.
The links 17 extend upward and have each 75
a flattened portion 19 at its upper end pro-
vided with a plurality of bolt holes 20.
The holes of each portion 19 are alined and
adapted to receive a transverse bolt 21. The
portions 19 are engaged on opposite sides of 80
the standard or mast 22 of a riding buster
or other agricultural machine (not shown).
By provision of the holes 20 the links may
be adjusted whereby the drum will be prop-
erly supported or hung in cutting position. 85
While the arms 14 are more or less resili-
ent it is desirable to mount between each
side bar and each arm, a coil spring 23. For
maintaining the springs in vertical position
and limiting the spreading of each arm and 90
its adjacent bar, vertical bolts 24 are passed
through the springs and the bars and arms.
These bolts are held in position by nuts 25.
It is obvious that the links form rigid con-
nections and will not yield upward, but the 95
spring arms 14 and springs 23 will yield up-
ward and permit the side bars and drum to
swing upward when an obstruction which
would injure the cutting blades is encoun-
terect This arrangement preserves the cut- 100
ting edges of the blades and prolongs the
life of the same.
On the members 1 a yoke 26 is secured.
This yoke has a drag-hook 27 at each end
which extends rearwardly and is curved 105
downwardly on the outer side of the adja-991,601.
