GEORGE EDWARD HARPER, OF MYRA, TEXAS.
STALK-CUTTER.No. 862,473.
To all whom it may concern:
Be it known that I, GEORGE EDWARD I-IARPER, a
citizen of the United States, residing at Myra, in the
county of Cooke and State of Texas, have invented a
5 new and useful Stalk-Cutter, of which the following is
a specification.
This invention relates to stalk cutters and its ob-
ject is to provide a device of this character which is of
simple and durable construction, which can be readily
10 manipulated, and which will operate to cut stalks si-
multaneously along two rows.
A still further object is to provide a simple arrange-
ment of cutting blades whereby the stalks can be
quickly cut in an efficient manner and will be caused to
15 assume positions above the blades where they will not
interfere with the further cutting operation.
With these and other objects in view the invention
consists of certain novel features of construction and
combinations of parts which will be hereinafter more
20 fully described and pointed out in the claims.
In the accompanying drawings is shown the preferred
form of the invention.
In said drawings: Figure 1 is a side elevation of the
machine in use, one of the supporting 'wheels thereof
25 being removed; Fig. 2 is a plan view of the machine;
Fig. 3 is an enlarged view showing the axle and the
guides in elevation and the adjustable bar in section;
and Fig. 4 is a detail view showing a modified means
for adjusting the blade.
30 Referring to the figures by characters of reference, 1
is an axle supported by wheels 2 and carrying a tongue
3 which is connected to the axle by means of suitable
braces 4. A driver's seat 5 is suitably supported above
the tongue and disposed adjacent thereto is a toothed
35 sector 0 designed to be engaged by a spring pressed
plunger 7 connected to an actuating lever 8. This le-
ver is fulcrumed at its lower end, as shown at 9, and
has an arm 1.0 extending rearwardly therefrom. Pivot-
ally connected to this arm is a link 11 which is also piv-
40 oted to a bar 1.2. The forward end of this bar is ful-
crumed as shown at 13 between brackets 14 which are
secured to and suspended from opposite faces of the
tongue 3 and are also suitably braced by means of arms
15 which are fastened to the axle 1. The bar 12 is
45 mounted to swing vertically between hangers 16 which
are fastened to and are suspended from the axle to con-
stitute guides. Each of these hangers is preferably
formed with an integral brace 17 which is also con-
nected to the axle.
50 Secured to the opposite faces of the rear portion of
the bar 12 are spacing blocks 18 to the outer faces of
which are detachably secured plates 19. Extending
rearwardly and laterally from these plates are obliquely
disposed blades 20, the forward edges 21 of which are
55 sharpened. These blades are so proportioned as to ex-Patented Aug. 6, 1907.
tend across two rows of stalks and by manipulating the
lever 8 the bar 12 can be'swung upon its fulcrum 13 so
as to raise or lower the blades.
In using the machine herein described the same is
driven along two rows of stalks, each row being re- 60
ceived between the tongue 3 and one of the wheels 2.
As the machine moves forward the stalks are succes-
sively bent forward by the axle 1 and the braces 4 con-
nected thereto and the blades 20 contact with the
stalks where the bends are produced. As these blades 65
are obliquely disposed they will produce a shearing ac-
tion and will quickly cut through the stalks which, as
soon as severed, will spring upward and fall upon the
blades so that the blades will pass longitudinally there-
under against the next stalks and without being inter- 70
fered with by the stalks which have been cut. Con-
siderable importance is attached to the provision of
means for first bending the stalks and then cutting them
where the bend is greatest so that the stalks will be
caused to snap upward and fall upon the blades. If the 75
stalks should assume positions beneath the blades the
effective operation of the machine would be interfered
with. The blades can be adjusted laterally to operate
upon rows different distances apart by putting thicker
or thinner spacing blocks 18 therebetween. The oper- 80
ator can easily adjust the blades vertically by means of
lever 8 so as to permit them to strike the stalks at the
proper points and to prevent them from coming into
contact with large stones, stumps, etc., which may be
in the path thereof. 85
As shown in Fig. 4 the blades 22 may be pivotally
mounted upon ears 23 which extend from the support-
ing means. A series of apertures 24 is formed in each
of the ears for the reception of a bolt whereby the blades
can be locked at any desired angle and adjustably con- 90
nected links 25 are pivotally connected to the blades to
constitute braces. By providing a connection such as
described the blades can be independently adjusted to
any desired angle.
What is claimed is: 95
1. The combination with portable stalk bending means;
of guide hangers depending therefrom, a bar pivotally sup-
ported by said means and movable between the hangers,
means for adjusting the bar between the hangers, and an ob-
limluely disposed cutting blade extending from and movable 1.00
with the bar.
2. The combination with portable stalk bending means;
of guide hangers depending therefrom, a bar pivotally sup-
ported by said means and adjustable between the hangers,
and cutting blades adjustably connected to the bar and 1.05
movable therewith.
In testimony that I claim the foregoing as my own, I
have hereto affixed my signature in the presence of two
witnesses.
