WILLIA 3. JOHNSON, OF MONDAY, TEXAS.
SEED-PLANTER.Specification of Letters Patent.
Patented Feb.16,1915.
Application filed January 2, 1914. Serial No. 509,992.
To all whom it may concern:
Be it known that I. WILLIAM J. JOHNSON,
a citizen of the United States, resident of
Sunday, in the county of Knox and State of
Texas, have made a certain new and useful
Invention in Adjustable Covering Attach-
ments for Seed-Planters; and I declare the
following to be a full, clear, and exact de-
scription of the same, such as will enable
others skilled in the art to which it apper-
tains to make and use the invention, refer-
ence being had to the accompanying draw-
ings, and to letters or figures of reference
marked thereon, which form a part of this
specification.
Figure 1 is a side view of the attachment,
as applied, the raised portions of the coverer
plows being shown in dotted lines. Fig. 2
is a plan view of the attachment as applied,
parts being broken away. Fig. 3 is a dia-
grammatic side view of the attachment, as
applied, illustrating the simultaneous verti-
cal adjustment of the main and coverer
plows. Fig. 4 is a similar view illustrating
the simultaneous adjustment of the main
and coverer plows to alter their pitch.
The object of the invention is to provide
certain improvements upon a riding or wheel
planting plow, which are designed to facili-
tate its use as a listing plow, and also to in-
crease its usefulness as a planter.
The invention consists in the novel con-
struction and combinations of parts, as here-
inafter set forth.
The invention is designed mainly for use
with plows wherein the seat is in rear of the
axle and the seed box in front of the seat,
and is shown as applied to the type of
planter patented February 20, 1906, Number
812,925.
In the accompanying drawings, illustrat-
ing the invention, the numeral 2 indicates
the main or draft frame of the planting
plow, having the parallel side bars 3, prefer-
ably horizontally curved in rear in the ordi-
nary way and being supported by the axle
of the wheels.
Near the clevis, which is connected to the
pole 1, bars 2a of an auxiliary frame are pro-
vided with an upward projecting ratchet 4,
having engagement with the pawl 5 of a
right-angle lever 6, the long rear arm of
which extends backward, substantially par-
allel with the draft frame, to within a con-
venient distance of the seat 7, which is sup-
ported on the framing in rear of the axle.The vertical arm 8 of the right-angle lever
is pivoted to beam 2a, between the arms of
the ratchet, and it extends normally upward,
substantially to a level with the seat. In 60
the construction shown, the position of the
seat is about as far in rear of the axle as the
position of the ratchet is in front of it.
To the front of the draft frame, upon the
side bars 3, is pivoted a long secondary 65
frame 9, the rear parallel arms of which
extend back of the axle and substantially
below the seat. To the rear portions of the
secondary frame are secured standards of
the adjustable covering blades 10, these be- 70
ing connected to the rear lower and nor-
mally horizontal portions 16 of the arms by
bracket fastenings 12, which provide for
horizontal as well as vertical adjustment of
the shanks of the covering blades. 75
To secure suitable rigidity, the secondary
frame is usually made of ribbed iron, and its
lateral arms 11 are provided with rearward
and downward guiding bends or portions
14, in order to bring its rear portions 16 80
nearer to the ground than its front portions.
In this way it is designed to provide for the
use of short and rigid shanks for the cover-
ing blades, and to facilitate such adjustments
as the operator may find appropriate in 85
working the planter.
In one of the rear lower portions 16 of
the secondary frame are made apertures or
bearings 15 and 17, one some distance in
rear of the other, for attaching the rear end go
of the long curved connecting rod 13, which
passes above the bend of the secondary
frame and is pivoted by its front end to the
right-angle lever, about midway its upright
branch. When the connecting rod is piv- 95
oted to the rear perforation or bearing 17,
the secondary frame will be tilted up in rear
at a high angle, and the covering blades will
be lifted high above the ground, the adjust-
ment of the right-angle lever for this posi- 100
tion of the secondary frame being substan-
tially horizontal and out of the way of the
operator.
Because of the length of the secondary
beam from its pivotal point in front of the 105
axle to the covering attachments in rear
thereof, its adjustments may be regulated
by the right-angle lever for such small vari-
ations in the position of the covering blades
as may be advisable, or to provide for lifting 110
them to greater extent. By means, there-
fore, 'of the angle lever and ratchet, the see-1,128,78'7.
