ondary frame and the connecting rod, the
covering blades may be raised and held high
above the ground. And by means of this
lever and the connecting rod, in substan-
5 tially the same position, the covering blades
can be adjusted to suit small variations of
depth required in the planting, and held to
the adjustment in such wise as to prevent
casual rising or falling of the covering
10 blades.
The plow 18 is supported from the aux-
iliary frame bars 2a, which are pivoted to
the side bars 3 at 19, and may be raised or
lowered with bars 2a substantially as.stated
15 in the patent referred to, by operation of a
lever 21', mounted upon the main frame and
having pawl engagement with the rack 22,
upon said frame to fix the lever in position
as adjusted, said lever having an arm 20 en-
20 gaging at its end with a slot 23 of the aux-
iliary frame. At the same time lever 6
(rigidly connected to the bars 2a by pivot 21
and pawl 5, engaging rack 4) will move
with the plow and with said bars, thereby,
25 through connecting rod 13, providing for
the raising or lowering of the covering
blades 10 simultaneously with the main
plow 18.
In the type of planter shown, the pitch
30 and comparative depth of the main plow
and covering blades is altered by tilting the
main frame 2 upon the axle shaft, the rela-
tion of the side bars 3 with the bars 2a be-
ing unchanged. This tilting is accom-
35 plished substantially as stated in the patent
referred to, by operation of a lever 24, hav-
ing an arm 25 connected at its end pivotally
at 26 with the upper end of a rod 27, the
lower end of said rod having pivotal con-
40 nection 28 with an arm 29 of the lever 21',
the lever 24 being mounted upon the draft
pole 1, a rack 30, also mounted upon said
draft pole, being engaged by a pawl of the
lever to fix the adjustment thereof. Thus
45 the covering blades, supported from bars
3 by secondary frame 9 and from bars 2
by connecting rod 13, will be moved rigidly
with the frame 2, in the operation stated.
In the present case, an adjustment of the
5o covering blades is provided for independ-
ently of the adjustment of the plow 18, in
order to avoid the necessity of taking off the8,787
covering blades when listing land, and fur-
ther in order to obtain different adjustments
of the covering blades for depth, without 55
disturbing the position of the plow 18; at
the same time providing for the simul-
taneous adjustment of the covering blades
and the plow 18 when desired.
What I claim is: 60
1. In a wheeled planting plow, an outer
main frame, an inner auxiliary frame piv-
oted forwardly to said main frame and car-
rying a plow standard and a main plow, a
secondary frame pivoted forwardly to said 65
main frame and carrying rear coverer plows,
lever-operated means mounted upon said
main frame and engaging said auxiliary
frame to effect simultaneous adjustment ver-
tically of said auxiliary frame, the main 70
plow, said secondary frame and the rear
coverer plows, and lever-operated means for
separate vertical adjustment of said sec-
ondary frame and the rear coverer plows
without sacrifice of said simultaneous ad- 75
justment.
2. In a wheeled planting plow, an outer
main frame, an inner auxiliary frame piv-
oted forwardly to said main frame and car-
rying a plow standard and a main plow, a 8o
secondary frame pivoted forwardly to said
main frame and carrying rear coverer plows,
lever-operated means mounted upon said
main frame and engaging said auxiliary
frame to effect simultaneous adjustment ver- 85
tically of said auxiliary frame, the main
plow, said secondary frame and the rear
coverer plows, and lever-operated means for
separate vertical adjustment of said sec-
ondary frame and the rear coverer plows goo
without sacrifice of said simultaneous ad-
justment, comprising a rack rigidly secured
to the forward part of said inner frame, a
lever pivoted at its lower end to the for-
ward part of the main frame and having a ol
releasable pawl engagement with said rack,
and a connecting rod between said lever and
said secondary frame.
In testimony whereof I affix my signa-
ture, in presence of two witnesses.
