heeper, JOSEF KOREJS, Merchant, all of Altbünzlau, and HYNEK SIPEK, Merchant,
of Nymburk, all in the Province of Bohemia, Austro-Hungarian Empire, do
hereby declare the nature of the present invention to be as follows :—
The present invention relates to a machine for sowing seed potatoes and its
essential features are as set forth in the following description.
The working parts of the machine are carried on a wagon frame having
shafts or a chain hook in front and guiding shafts behind. On the
axle of one of the wheels of the frame a pinion is or pinions are
mounted and the same axle also carries standards for a superposed
shaft. This superposed shaft carries in its centre a rotating disc or seeding wheel
and on its end a pinion or pinions which gear with those on the wagon axle
so that when the wagon part is moved the disc or seeding wheel rotates in the
same ratio.
In addition to the standards, superposed shaft and rotating disc or seeding
wheel, the wagon frame carries a seed box of suitable material, tapering down
towards the under part and resting on standards carried on the front axle.
This seed box is so arranged that the seeding wheel can pass through it and it
is normally kept full of seed potatoes.
Attached to the rotating disc or seeding wheel are carrying cups arranged to
carry one seed potato. These cups are provided with a sliding bottom which is
actuated by a small catch lever and a spring, and they are also provided with
springs inside and are so arranged in construction that they can allow a seed
potato to pass out sideways.
When the seeding wheel is turning through the seed box, a cup may pick up
more than one seed potato, but as the catch lever is held by a small catch or pin
La sliding bottom is thrust out slightly so that superfluous potatoes fall back,
the one wanted being meanwhile held by the inside springs.
Arranged vertically to the seeding wheel is a shoot or are shoots whose nozzles
or lower ends lead into the furrow. This shoot or these shoots is or are provided
with claps controlled by springs and actuated by gear on the seeding wheel in
such way that only one seed potato can pass out at a time. As the cups pass the
mouth of the shoot, each is caused by a catch to shoot out its seed potato laterally
into the shoot.
The machine can either be single or double, that is there can either be one or
two shoots and one or two seeding wheels. When one seeding wheel is used the
cups can also be arranged with two compartments.
The shafts at the rear of the machine can be fitted with ploughshares to prepare

page_text: fresh furrows as the machine is moving and also a device for earthing up the
furrows after seeding, or such devices may be arranged before the hind wheels of
the frame.

JOSEF KOREJS, of 110, Alt Bunzlau, and HYNEK SIPEK, of 128, Nymburk, all in the
Province of Bohemia, Austro-Hungarian Empire, Tailor, Merchant, Hotel Keeper,
Merchant and Merchant respectively, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The present invention relates to a machine for sowing seed potatoes and its
essential features are as set forth in the following description.
With reference to the accompanying drawings:
Fig. 1 is a side elevation.
Fig. 2 is a plan view.
Fig. 3 to 7 are detailed views of different parts of the machine.
The invention consists essentially of a combined scooping and seeding disc B,
a seed box A, a device for forming a furrow in the ground, a device for closing
same, the whole being carried on a transportable frame.
The machine shown in Fig. 1 and 2 is constructed for seeding two rows at
one time and has two seeding wheels; but as one half of the machine is precisely
similar to the other half, the following description will be principally of only
one half the machine.
On the principal frame 1, mounted on the wagon frame, is located the seed-
box A, formed of divisions 2, 3 and 4. The divisions 3 and 4 are inclined, a roof-
piece 5 being fitted between same which causes the box to taper like a spout.
finally ending in a channel 6. The box A. is further divided into three divisions
by two partitions 7 open underneath for the protection of the sowing discs B,
the centre division a being the largest and serving as store chamber in which the
seed potatoes are shaken about. Between the sowing disc B and the box division 2
is a metal wall 8 for effecting a proper closing or cut-off of the box A.
The seed potatoes which are shaken in the box A roll down the inclined
divisions 3, 4 and 5 into the outer compartment 6 and pass on towards the
channel 6 which is formed by two side walls 9 and a bottom 10.
The scooping and sowing discs B, B which reach inside the box A are loosely
mounted on the shafts 13 (14b Fig. 4 being the sleeve or box) having bearings 11
and 12 and are driven forward by clutches 14 controlled by springs 14", the
clutch being so arranged as to drive the discs in one direction only, so that only
the shaft is turned in the reverse motion of the machine, the disc B being
stationary. Each of the shafts 13 is driven from the hub of the wagon wheel
by gear 15 and 16 to 19.
The scooping and sowing devices are combined in one dise 13 consisting of a
disc 24 with scoops 35 on its periphery and a rim or drum 25 which is divided
up by straight (Fig. 7) or broken (Fig. 6) walls 28 into small compartments d.
Each scoop is provided with a moveable bottom and side 36 the side being of a
suitable springy material which is connected with a double-armed lever 31 by

page_text: means of arm 29 and bolt 30. The said lever 31 passes through a slot 34 in the
dise 24 on its other side and rotates on the pivot 32, being acted on in that posi-
tion by spiral spring 33.
The rim or drum 25 revolves within cover-pieces 26 and 27 Figs. 3 & 5 sp
as to be partially closed in by same, openings being left between cover pieces
above and below. The scoops 35 scoop and transport the seeds to a given level
at which the latter empty themselves into the compartment d.
For this purpose the scoops first pass through the channel 6 which is always
full of seeds and thus each scoop must take at least one seed along with it. After
passing the channel 6, the scoops arrive in the seed-box proper 6 and during the
passage through same, other seeda are drawn into said scoops. Seeing,
however, that it is only desired that each scoop lift one seed from the box 6, the
others have to be removed. This is effected by the moveable bottom 36 which is
made to work about in such way that the superfluous seeds heaped on to the scoop
are shaken off and fall back into the seed box.
The movement of the moveable bottom 36 is effected by sliding the lever 31
over a number of pins 38. These latter are attached to the standards 37 and
can be displaced in slot 41 to give as much movement to the bottom 36 as is
desired. Owing to this action only one potatoe seed remains in the scoop
and which is held fast by the spring side 36. The seed potatoe is then brought up
by the disc and is thrown out of the scoop by the contact of lever 31 with the
uppermost catch 38 80 as to fall in the corresponding compartment of the rim.
This division of the rim into compartments is to ensure the seeds being distributed
uniformly in the furrows. Openings are left so that the seeds can fall out in
proper order.
The furrows are formed by plough shares 42 adjustable by means of screws 51.
by turning the lever 43, the plough-shares can be raised or lowered as desired
by means of shaft 44, arm 46 and rod 47 with the carriers 48 mounted on frame 49.
The rod 50 serves for stiffening the guide-frame 49.
The device for closing the furrows consists of two metal sheets 62 which are
connected by means of arms 60 and 61 with a rotary carrier 59.
These sheets are raised by pressing down a lever 52 which rotates round a
shaft 53 and which is done by means of arm 55 connected with the carrier 59.
In order to sow the potatoes farther apart or nearer together, as may be desired,
pinion gear 16 to 18 is mounted on a lever-arm 20. The latter rotates round
the axle of the hind wheels and with its other end is attached to a guide-piece 21
in any known way. By altering the position of the lever-arm 20, different sizes
of wheels can be fitted on to the shaft 13 of the sowing disc and give to this the
desired speed. When the lever 20 is disconnected by means of gear 18 and 19
the corresponding sowing disc remains stationary.
The potatoe-seed sowing machine described can be used with two or more dises
so as to sow seeds in several furrows at a time. The sowing and scooping devices
can also be combined in different ways. For instance, two scooping devices
(disc 24) and one sowing device (rim 25) could be combined, in which case the
latter device would serve the other two. Or two sowing devices can be combined
with one scooping device. in which case the latter will be fed from both sides.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:
I. Potatoe-seed sowing machine the sowing portion of which consists of a
combined scooping and sowing disc B provided with scoops 35 and with a rim 25
