I, MATO ZIVKOVIC, of No. 43, Oberstadt, Essek, Hungary, Director of a Financial
Institution, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement: ―
My invention relates to a construction of plough provided with a seed hopper
and appliances whereby seed can be sown simultaneously with the ploughing
operation. Such an arrangement is of great advantage for small holdings where
the available manual labour is limited.
In this construction the delivery of the seed from the seed hopper is controlled
by means of toothed gearing from the running wheel of the plough.
I will describe the construction with. reference to the accompanying drawing,
in which Fig. 1 shews a back view of the sowing plough, Fig. 2 an inner side
view of the sowing devices, and Fig. 3 a longitudinal section through the same.
The plough proper with its plough share a and framing is of any suitable
known construction, with the exception that the axle d, formed with several bends,
is extended beyond the larger running wheel c, and carries at its extremity an iron
upright which in its turn supports the seed hopper c. The latter is however
not fixed directly upon the upright f, but is connected thereto by the following
nicans. The upright has a slot through which passes a pin h fixed to the
hopper, which pin is connected through the link with the front shorter arm
of the two armed lever k turning on a pivot k fixed to the upright f. The long
rear arm of the lever k carries an adjustable weight, and is formed with a
handle at its end.
The bottom of the hopper e which is closed at top by a cover a is inclined, and
the interior of the hopper is divided by a partition into two compartments as
shewn at Fig. 3, which compartments communicate with each other by means of an
opening such opening being capable of being regulated or closed by means of a
slide that can be actuated from the side of the hopper. The upper compart-
ment I serves as seed reservoir from which, at intervals the required seed is
conveyed into the lower compartment II. From the latter the seed is conveyed
through the opening and channel into the inclined seed shoot m. The seed is
for this purpose conveyed from the bottom of the compartment II to the opening
by means of the scoops o which revolve with the horizontal axis n. This axis
carries on its end projecting through the hopper a toothed pinion n¹ gearing with
a pinion c¹ which is fixed to the extended hub of the running wheel c, and conse-
quently runs loose on the axle d.
Thus on the forward motion of the plough, the pinion c¹ imparts rotary motion
through and n to the scoops o, whereby the seed is discharged in uniform
quantities and at regular intervals into the shoot m which delivers it into the
furrow previously cut by the plough.
By the above described mode of connection of the hopper e with the upright f,
the hopper can be thrown out of action, so that the ploughing can proceed without
owing seed.

page_text: This is effected simply by depressing the lever whereby the front arm thereof
is made to raise the hopper by means of the link and pin h to such an extent that
the pinion n¹ is raised out of gear with the pinion c¹ the axis n, being made to
slide in the slot fi of the upright f.
The hopper is more or less balanced by the adjustable counterweight k³.
The shoot m is made adjustable in its angular position, so as to give the issuing
seed the desired direction; for this purpose it is fixed to the short arm p of a
lever pivotted loose on the axle d, and whose upward curved long arm r is adjustably
attached to the upright fuby, means of a setting screw passing through a slot of
the lever, so that by loosening this screw the lever and consequently the angular
position of the shoot can be adjusted..
The hopper e may be provided with two or more shoots m and corresponding
scoops ; so as to provide-two or more simultaneous discharges of seed.
.
Having now, particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:
1. A sowing plough consisting of the combination with a plough of a seed
hopper carried by an extension of the running wheel axle and containing rotary
scoops actuated from the running wheel by toothed gearing, which scoops discharge
the seed into a shoot carried by the said extended axle, substantially as described.
2. In the sowing plough referred to in the first claim, arranging the hopper 'e to
be raised or lowered for the purpose of putting the scoops o in or out of gear with
the driving pinion c, by connecting the hopper by a link i with the lever k
pivotted to the upright f, substantially as described.
3. In the sowing plough referred to in the first claim, carrying the seed shoot m
on a two-armed lever pr, pivotted on the running wheel axle, and adjustably
connected to the upright f, for the purpose of adjusting the angular position of
the shoot, substantially as described.
4. A sowing plough combined and operating as herein described with reference
to, the drawing.
