through the slotted end of a crank-arm D
which is mounted on a horizontal rock-shaf
E and provided with a transverse pin d, passe
loosely through the slot in the arm C. Th
5 rock-shaft E will carry a series of the arms D
one for each hoe, and will be provided witl
the u-ual connections by which to turn it an(
lock it in different positions. Each of thi
arms C is encircled by a spiral spring F, bear
Io ing at its lower end on a shoulderon the amrn
and at its upper end beneath and against th
crank-arm D, the end of which is widened
sufficiently to give it a firm bearing on the
spring.
15 When the rock-shaft is turned to throw the
crank-arms D downward, the latter compress
the springs, which apply a corresponding
downward pressure upon the hoes. When
the shaft and crank-arms are turned in the
20 opposite direction, the hinge d acts on reach-
ing the upper ends of the slots to lift the'arms
C and thereby raise the hoe.
The slotted arm C is provided near its lower
end with a series of transverse holes ca' at dif-
25 ferent heights to receive a transverse bolt c2,
which may be employed to sustain the lower
end of the spring at different heights in or-
der to vary its normal tension, and thus cause
it to apply more or less pressure in propor-
30 tion to the depression of the crank-arms.
The vertical flange a3 has its upper end
widened, as shown in Fig. 2, so as to bear
closelybetween' the branches of the arm C in
order to hold the shoe the more firmly in an
35 upright position and prevent it from tipping
or canting sidewise.
H represents the follower or pressure wheel,
which may be made of any suitable size and
form, but which is preferably cast complete
40 in one piece, as shown, with a fiat periphery
and three spokes, it being found that the three
spokes uniformly spaced are free from the
liability to accumulate and carry foreign mat-
ters which attend the use of ordinary wheels
45 having a large number of spokes. Thewheel
is seated between and carried by the rear
ends of two parallel longitudinal arms I I',
which lie on opposite sides of the runner, be-
ing connected by and mounted upon a hori-
50 zontal pivot-bolt i, passed through the flange
a3 on the front of the runner-tube. The for-
ward ends of these arms are made of fiat cir-
cular form in order to have an extended bear-
ing on the flange, which is correspondingly
55 shaped, so that the arms are prevented from
swaying laterally. The arms are also guided
vertically, so as to keep. the wheel at all times
directly behind the runner and in the furrow
by a vertical flange a9, formed on the rear side
60 of the runner-hoe and bearing between bosses
or projections on the inner sides of the wheel-
carrying arms, as shown in Fig. 3.
The wheel-carrying arms are urged down-
ward in relation to the runner by means of a
65 spiral spring J, seated at its lower end upon), the arms and at its upper end beneathan arm
t a'lon the back of the hoe. The spring is
i guided and held in place by a vertical bar K,
e seated at its lower end upon the bolt k, pass-
i, ing through the wheel-carrying arm. Theup-
1 per end of the bar K passes through and is
d guided by the arm a1" on the runner-tube, so
e that it may slide freely upward and down-
- ward as the wheel and arms rise and fall in
i relation to the runner.
e L is a scraper-arm having one end adapted
to fit over the periphery of the wheel and the
3 opposite end attached to the top of the verti-
cal bar K, so that as the arms swing upward
and downward through the wheel they act f
s through the rod to raise and lower the scraper,
thus maintaining its relation to the wheel.
The scraper-arm is by preference slipped
loosely over the upper end of the rod K and
secured by two pins 1, , passed through the E
bar, this arrangement permitting the rear or
active end of the scraper to rise and fall as
Sfar as may be necessary to adapt itself to the
surface of the wheel and to prevent accumu-
lations thereon.
It will be observed that the active end of
the sciaper L extends across the periphery of
the wheel and that its ends are turned down-
ward past the edges of the wheel, whereby it
is the better adapted for detaching the adher- '
ing mass of earth which may project laterally
beyond the wheel.
An additional scraper M to act on the pe-
riphery of the wheel may also be attached rig-
idly to the wheel-carrying arms bythe through- i
bolt k, as shown, or otherwise.
Having thus described our invention, what
we claim is-
1. In a seeding-machine, the combination of
a'runner-hoe and abackwardly-curvedspring- i
arm attached to the front part thereof and ex-
tending under the runners, substantially as
shown and described, to hold down stalks and
other obstructive matters that the runner may
ride thereover. 1:
2. In a seeding-machine, the combination of
the runner-hoe, the vertical pressure-arm piv-
oted thereto and having its upper end slotted,
the crank-arm connected to the pressure-arm
by a bolt passing through the slot therein,the ii
spring encircling the pressure-arm, and an
adjustable seat for the spring, by the adjust-
ment of which the spring-pressure may be
varied.
3. The combination of the runner-hoe hav- 12
ing a guide a1o, the follower-wheel, the wheel-
carrying arms jointed to the hoe to swing ver-
tically, the bar K, jointed to said arms and ex-
tending through the guide a10, the spring en-
circling the rod between the guide and the i2
wheel-carrying arms to press the latter down,
and the wheel-scraper attached to the upper .
end of the bar K.

C, having the. forked lower end, in combina- X300
