ABRAM LEE AND EDWARD R. SINKS, OF LA GRANGE, TEXAS.
IM:PCVEMENT IN SEEDING-MACHINES.
Spociicntion forming I a1 of Lett rs PatenlNo. 151,494, dated Junoe 2, 1874; application filed
Janmlry 29, 1874.To all whom it may concert:
De it known that we, \Ancalr TLs and ED-
WARD RANDOLPi SLxKS, of La Grange, in the
county of Fayette and S'tate of Texas, have
invented certain m!unpovements in Seeding-
IMac.hines; of which the following is a speeiti
cation:
This invention consists in certain novel
combinations of parts, whereby an efficient
a.pparatns for planting seeds in drills is se-
cured, and whereby the covering-sliares, &c.,
of the apparatus may ibe lifted clear of the
ground whiie required in the exigencies of
use
Figure 1 is a side view and partial vertical
section of my improved seeding - meacine,
adapted for seeding in drills or rows, with
the covering-shares lowered for work. Fig.
2 is a side view of the same, showing the said
shares lifted.
The axle A is provided with the wheels B,
made fast thereon, and has projecting forward
from its outer end portions two arms, a, from
which extend upward two other arms, b, united
at the top by a cross-bar, c, the whole consti-
tuting, in thet, a kind of elbow-lever. The
forward extremities of the arms c-in other
words, the bends of the elbow-levers a b c
aforesaid-are pivoted by bolts, at f, to the
sides of the main frame C, which carries the
hopper D, and has at its forward end the fur-
rowing-share A*, tlanked on each side by a
curved runner, B-. To the rear end of the
main frame are attached the covering-shares
E. AWhen the parts are in their normal con-
dition the weight of the main frame and its
attached covering-slhares E depresses the same
nutil it rests ipon the axle A, with the cover-
ing-shares penetrating the soil to the desired
depth. This depth may be adjusted at will,
the shanks or standards a' of the shares E
passing through slots or staples in the longi-
tudinal parts of the main frame, and secured
by pins o' passing through the said parts of
the frame and through any one of a mutber
of holes duly provided to each standard.
Moreover, each standard has projecting ob-
liquely forward and upward from it a brace,
b', pivoted thereto and passing through cer-
tain other slots or sockets provided to the
frame, and made adjustahle in a manner simi-lar to the standards themselves, o that the
inclination of the latter may be varied to bring
the covering-shares at any desired pitch or
angle to the surface of the ground. The fur-
rowing-share is provided with a similar brace,
e', and may also be adjusted in substantially
the same manner. The runners 3xI are also
furnished with like adjustable braces f', and
the length and the pitch or inclination of the
same umay be adjusted in the same manner to
bring the furrowing-share to make any pre-
ferred depth of furrow, or to work at any an-
gle that may be found best. By simply forc-
ing backward the arms b of the elbow ca b c
the elbow portions of the said lever will lift
the rear end of the main frame, and thereby
bring the covering-shares clear of the ground,
as shown in dotted outline in Fig. 2. In the
bottom of the hopper is an orifice, g, at the
sides of which are lateral grooves or guides,
which receive a horizontal slide or gate, F, by
the longitudinal movement of which the avail-
able size of the orifice g is increased or dimin-
ished. Working in vertical guides at the back
of the hopper is a vibrating bar, G, extending
into and through the orifice g. This bar G
has a longitudinal series of inwardly-project-
ing spikes, g". Provided at the back of the
hopper is a transverse shaft, m, having a
crank, ca", at one end, and a pulley, b", at the
other. The crank a" connects with the bar
G by a rod, S. A band, C", from the pulley
b", passes through and over a double-grooved
pulley, H, of larger diameter, a band, l, from
which passes over a driving-pulley, e, on the
axle A. The sllaft of the pulley 1 extends
transversely through the hopper, and within
the same is furnished with radial arms r. The
wheels B being fast upon the axle, as the ma-
chine moves forward the system of pulleys
and bands rotate the shaft am, which, by its
crank a" and the rod s, gives a reciprocating
or vibratory motion to the bar G, simultane-
ounsly with which the shift I receives a motion
of rotation. This operation of the bar G and
shaft I causes the spikes p' of the one and the
radial arms r of the other to agitate the mass
and feed the same uniforml and without
clogging through the orifice g, whence it falls
into the furrow or drill made in advance of
the furrowing-share, and is covered by the
