JESSIE V. EDWARDS, OF BEEVILLE, TEXAS.
STALK-CUTTER.Specification of Letters Patent.
Patented May 26, 1914.
Application filed June 25, 1913. Serial No. 775,758.
To all whom it may concern:
Be it known that I, JEss I V. EDWARDS,
citizen of the United States, residing at
Beeville, in the county of Bee and State of
5 Texas, have invented certain new and use-
ful Improvements in Stalk-Cutters, of which
the following is a specification.
This invention relates to stalk cutters, and
has for its object the provision of a machine
10 composed of few parts which, as it is drawn
over a field, will cut up stalks and stems of
weeds and vines so that the field may be
easily prepared for cultivation.
An object of the invention is to provide
15 novel means whereby as the machine is
drawn over the field the cutter will be given
a rocking or oscillatory movement so that
the edges of the blades will be caused to
positively pass through the stems and stalks
20 in their paths.
Another object of the invention is to pro-
vide means whereby the extent of the rock-
ing or oscillatory movement of the blades
may be regulated, and a still further ob-
25 ject of the invention is to provide novel
means for holding the cutter to its work
and for raising it so as to clear rocks or
other unyielding obstructions.
Finally, the object of the invention is to
80 improve, generally, the construction and ar-
rangement of parts of a stalk cutter to the
end that the efficiency and durability of the
machine may be increased without any in-
crease in the cost of production and up-keep.
35 These stated objects, and such other in-
cidental objects as will appear from the fol-
lowing description, are attained in an appa-
ratus of the type illustrated in the accom-
panying drawings, and the invention con-
40 sists in certain novel features which will
be particularly pointed out in the claims
following the description.
In the drawings: Figure 1 is a rear ele-
vation of a stalk cutter constructed in ac-
45 cordance with my invention; Fig. 2 is a
sectional elevation of the same, the section
being taken on the line 2-2 of Fig. 1; Fig.
3 is an enlarged detail longitudinal section
of the means for raising and lowering the
50 cutter ; Fig. 4 is a horizontal section taken
on the line 4-4 of Fig. 3; Fig. 5 is a detail
view of a part of the supporting members;
Fig. 6 is a detail view of part of the means
for regulating the rocking movement of the
55 cutter; Figs. 7 and 8 are detail perspective
views showing means provided for support-ing the cutter shaft and the chain for ad-
justing the oscillation of the same.
In carrying out my invention, I employ an
axle 1 having a plurality of arched portions 60
2 and 3 and having supporting and carrying
wheels 4 mounted upon its ends. The.
tongue 5 is rigidly secured in any conven-
ient manner to the central arch 3 of the axle,
and whiiflletrees of any preferred arrange-665
mnent may be mounted upon the tongue to
permit draft animals to be connected there-
with so that the machine may be drawn
over the field to be treated. To the rear end
of the tongue 5 I secure a supporting plate 70
6 which projects rearwardly from the
tongue and carries a seat 7 for the driver at
its rear end. A loop or handle 8 is pro-
vided over the central arch 3 of the axle and
is constructed at its ends with forks 9 adapt- 75
ed to pass downwardly at the sides of the
axle and equipped at their lower ends with
plates or washers 10 extending under the
arch of the axle and nuts 11 fitted on the
ends of the said forks and turned home 80
against the said plates to secure the loop or
handle 8 rigidly in position upon the axle.
A shaft 12 is disposed immediately below
the axle and is provided with angular ends
upon which are fitted and secured angular 85
sleeves or eyes 13 from which crank arms
14: extend. The said shaft 12 is supported
from the axle by a. hanger 15 adjacent each
end. Each hanger consists of a stem or shank
provided at its upper end with a fork 16 9o
adapted to fit around the inner side portion
of the outer arch 2 of the axle and an eye
or loop 17 at the lower end of the said stem
or shank which fits around the shaft 12 so
as to form a bearing and support therefor. 95
A clip 18 is fitted over the axle immediately
adjacent each outer arch 2, and the sides of
this clip extend downwardly past the shaft
12 and carry a washer or plate 19 extending
between the sides of the clip under the axle 100
and bearing thereagainst and a similar
washer or plate 20 extending between the
sides of the clip and under the shaft. Be-
tween these two plates 19 and 20 bearings
21 are provided to fit around the shaft and 105
inclose the same and nuts 22 mounted on the
ends of the clip and turned home against
the lower plate 20 serve to secure the parts
together and prevent loss of the bearings.
The bearings are provided with end lugs or 110
extensions 23, as will be readily understood,
to fit around the sides of the clip so that1,097,617.
