UNITED STATES PATENT OFFICE
JOSEPH R. ERWIN, OF SABANNO, TEXAS.
PEANUT-HARVESTER.Specification of Letters Patent.
Patented Apr. 27,1915.
Application filed October 31, 1913. Serial No. 798,592.
To all wkom it may concern:
Be it known that I, JOSEPH R. ERwIN, a
citizen of the United States, residing at
Sabanno, in the county of Eastland and
5 State of Texas, have invented certain new
and useful Improvements in Peanut-Har-
vesters, of which the following is a specifi-
cation.
My invention relates to a new and useful
10 peanut harvester.
Its object is to provide a machine which
will travel along a row of peanut plants,
first uprooting the same, and then subject-
ing them to a process by which any earth
15 adhering to the peanuts is removed there-
from, the vines finally being deposited in
windrows, that the peanuts may cure.
Further objects are to provide mechanisms
for vertically adjusting the earth-turning
20 member of my machine, and for discharg-
ing a quantity of vines at any desired point
in the path of the machine.
Finally, the object of my invention is to
provide a device of the character described
25 that will be strong, durable, efficient and
simple and comparatively inexpensive to
produce, also one in which the several parts
will not be likely to get out of working
order.
30 With these and various other objects in
view, the invention has relation to certain
novel features of construction and opera-
tion, an example of which is described in
the following specification and illustrated
35 in the accompanying drawings, wherein:
Figure 1 is a plan view of my peanut har-
vester. Fig. 2 is a right side elevation view
of the same, the right-hand wheel being
omitted. Fig. 3 is a vertical sectional view
40 taken upon the line x-w of Fig. 1. Fig.
4 is a bottom view of the earth-turning
member. Fig. 5 is a perspective view of a
detail of the machine. Fig. 6 is a side ele-
vation view of another detail of construc-
45 tion. Fig. 7 is a fragmentary top view of
a certain conveyer embodied in my machine.
Fig. 8 is a sectional view of the same taken
upon the line y-y of Fig. 7. Fig. 9 is a
detail view showing in side elevation the
50 mounting of a plow standard upon the
tongue of the machine. Fig. 10 is a sec-
tional view of the same, the section being
taken upon the line z-s of Fig. 9.
Referring now more particularly to the
55 drawings, wherein like reference characters
designate similar parts in all the figures,the numerals 1, 2 and 3 respectively denote
the wheels, axle and tongue of my machine,
the axle being passed through the rear ends
of two parallel bars 4 which rigidly fasten 60
at their forward extremities at each side of
the tongue.
The earth-turning member of my machine
is mounted beneath the rear end of the
tongue and comprises a plow-share 5, land- 65
side bar 6, frog 7 and brace rod 8. To the
rear face of the plow share, there is secured
a plate 9, projecting a short distance above
the plow-share, the function of which plate
will presently be made clear. The earth- 70
turning member is carried fast upon the
lower end of a standard 10, extending up-
wardly adjacent to the tongue, and termi-
nating at a distance above the same.
Through said standard, a limited vertical 75
displacement may be communicated to the
earth-turning member, in which displace-
ment the standard is guided by a keeper
plate 11 secured to one of the bars 4. The
keeper plate is formed with slots in which so
horizontal rollers 12 are mounted and simi-
lar rollers 12a are also mounted in depres-
sions formed in the left hand plate 4. The
rollers 12 and 12a turn upon the lateral
faces of the standard during its vertical 85
motion, minimizing the resulting friction.
To further reduce friction resulting from
vertical displacement of the standard, the
front and rear edges thereof are respectively
engaged by rollers 13 carried by a bracket 90
13a surmounted upon the tongue.
The means for raising and lowering the
earth-turning member comprise a lever 14,
pivoted at its lower extremity upon a ver-
tical bar 15, and formed with an integral 95
quadrant 16 centered at the pivot point of
the lever and engaging a rack 17 formed
upon the upper portion of the rear edge of
the standard. The lever 14 is adapted to be
held in various positions of angular adjust- 100
ment in the usual well known manner. The
bar 15 is mounted fast at its lower end upon -
the bar 4 to which the keeper plate 11 is
secured.
In lieu of a mold-board, there are secured 105
to the plate 9 of the earth-turning member a
plurality of slightly spaced rods 18, which
extend rearwardly at an upward inclination,
passing over the axle at their rear ends, and
curving around the same through approxi- 110
mately half a circle. A bar 19 extends trans-
versely across the rear ends of said rods e-1,137,594.
