avoiding, as it were, the danger of the rub-
bish clogging up with the seed box drive
mechanism, which is usually the case when
such mechanism is disposed close to the
5 ground.
As a simple and effective driving means I
employ drive shafts N journaled in short ver-
tical standards M projected up from the axle,
upon the ends of which are held slidable
:o gears n which are adapted to be slid into
gear with gear members qm' on the hubs of
the drive wheels.
Upon the ends of the stirrer and dropping
wheel shafts are secured sprocket wheels 7n
15 and o over which and sprocket wheels p keyed
to the shafts N pass the drive chains. Thus
it will be readily understood that as the ma-
chine travels over the field and the gears m
are slid into gear with gears on the drive
20 wheels, the seed dropping devices will be in
operation.
Below each planter frame G is disposed a
supplemental planter frame P, of a width cor-
responding to that of frames G, and such
25 frames consist each of a pair of side beams
p' the ends of which curve down as at p2 and
form bearings to receive the covering shovels
p, such beams being braced and spaced apart
by the spacing members p', secured between
30 such beams, by the bolts p6.
At the front end of the beams p' are rigidly
secured clevis members Q, to which are ad-
justably secured bail members I, the front
ends of which terminate in bifurcated disk
35 like ears r centrally apertured as at r' which
ears are pivotally secured to disk like ears s
on the rear ends of horizontal beams S, which
are rigidly secured to the main frame, in a
manner most clearly shown in Figs. 2 and 3
40 of the drawings. By reference to such fig-
ures it will be seen that bolted to the front
bar C is a series of clips CX to which are
bolted a series of depending frames T, each
formed of a vertical member t, a horizontal
45 portion t2 and a rearwardly and upwardly ex-
tending brace member t' which is secured at
its upper end to the axle, and to such portions
t and t' are secured the beams S as shown.
To brace the several frames T together, I
50 use apertured plates t3, which are secured to
and projected rearward from the inclined
member t', through which passes a tie rod t4,
as most clearly shown in Figs. 2 and 3; and
to horizontal members P, are secured guide
55 or angle plates tP.
t"indicate guide boxes secured to the beams
S to register with the guides t as shown.
U indicates opener plows, the standards it
of which are guided and are held for vertical
60 adjustment in the guides t5 t1, such adjust-
ment being provided by connecting the up-
per ends of such standards with flexible con-
nections V, the upper ends of which are
wound about a shaft W journaled on the top
65 of the frames G, which shaft has a hand wheel
W' which in the practical construction hasdetent devices, (not shown,) whereby it can
be rotated and held to its desired position
when it is desired to adjust the opener plows.
Upon the frame P is secured a hopper PX 70
which receives the seed from the upper hop-
per, and which has a discharge spout or boot
p8, at the front end of which is secured the
usual opener plow p9, such boot being braced
to the side beams p' as clearly shown in the 75
drawings.
Z indicates the driver's seat.
From the foregoing description taken in
connection with the drawings, the complete
operation and the advantages of my improved 80o
machine will be readily understood.
It will be observed that by connecting the
seed box frames G to the main frame in the
manner shown the same can be easily ad-
justed laterally to plant rows such distances 85
apart as may be desired. Furthermore by
connecting the furrow opener plows to the
main frame as shown, it is manifest, by mov-
ing the clip guides on the front bar C and the
frames T, such plows can be readily set, rela- 90o
tively to the adjustment of frames G, and as
such frames T are set, it follows the planter
or digger frames P can be moved laterally to
register with the said upper frames G.
By connecting the framesP with theframes 95
T in the manner shown and described, such
frames P while being held from lateral move-
ment, will be free to move vertically to ac-
commodate themselves to the unevenness of
the ground. Finally by constructing the sev- roo
eral parts of the machine in the manner
shown, the same will effectively serve as an
automatic planter, adapted to plant a num-
ber of rows at one operation, in which the
services of one man will be required, that of o5
the driver.
In the practical construction of my im-
proved machine, the seed boxes may be held
for longitudinal adjustment on the frames G,
whereby to take up the slack of the drive iro
chains, when desired.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is-
1. An automatic planting machine com- 115
prising a frame, including the main axle, the
drive wheels, and a front bar parallel with
the axle, a series of depending frames se-
cured to such bar and axle, a series of opener
plows held on such frames, a series of digger 12o
or planting devices, secured and projected
rearward from such depending frames, a se-
ries of supplemental frames mounted and se-
cured on the axle and front bar and provided
with extensions projected rearward over the 125
digger or planting devices and seed dropping
mechanism mounted on the said rearward
extensions over the digger devices, and means
for operating such seed dropping devices
from the main drive shaft, all arranged sub- 13o
stantially as shown and for the purposes de-
scribed.
