I, ANDREAS GEORG HEINRICH WILHELM KLAGGES of Niedernfelder-
strasse, 13, Hamburg-Veddel, Germany, Machinist, do hereby declare the nature
of this invention to be as follows:-
-
Portable sowing apparatus having horizontal scattering wheels, such as
heretofore used, work slowly and disadvantageously because the scattering wheel
must be closed to the extent of half its periphery in order to prevent the repeated
scattering of seed over the same ground.
Now sowing apparatus according to this invention is not open to such an
objection; it works in a perfectly uniform manner and gives about double the
output with the same power.
The apparatus is illustrated in the accompanying drawings,
Fig. 1 shewing an elevation with part of the side wall omitted, and
Fig. 2 shewing a plan thereof.
a is a casing for the reception of the seed; it is provided with a tapering bottom
forming a hopper or funnel that terminates in a channel b in which a regulating
slide c is located. In front of the outlet of said channel there is arranged a
scattering funnel d which is capable of being rotated by means of the shaft f. The
shaft is driven by hand through the medium of the bevel wheels 9 and the pair
of wheels h.
In order to facilitate the flow of the seed into the rotating funnel, the latter is
connected with the shaft f not by straight radial arms, but by means of a bent
bridge piece i arranged at the narrowest part of the funnel. This arrangement
serves to effect a uniform scattering of the seed, which is not possible in the case
of scattering funnels with radial arms at the widest part of the funnel, because in
such cases the arms hinder the movement of the seed.
When it is desired to scatter the seed to the greatest possible distance, the
internal surface of the funnel may be provided with a number of curved ribs.

COMPLETE SPECIFICATION.
Improvements in Seed-sowing Apparatus.
I, ANDREAS GEORG HEINRICH WILHELM KLAGGES, of Niedernfelder-
strasse 13, Hamburg-Veddel, Germany, Machinist, 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 :—
Seed sowing apparatus having scattering funnels or wheels rotating about a
horizontal axis, possess as heretofore constructed, the disadvantage that the seed
is not able to issue freely from the said funnels or wheels because the devices for
fixing the latter have obstructed the outlet for the seed and have often imparted
to the issuing seed quite a different direction to that which would have been
imparted to it if the said outlet were unobstructed. The consequence of this has
D927

page_text: been that no seed has been sown in some places, whilst other places have received
an extra quantity.
Now the object of my invention is to obviate this disadvantage for which
purpose the scattering funnel or wheel is formed with a perfectly free passage for
the seed.
Apparatus constructed according to my invention is illustrated in the drawings
filed with my Provisional Specification,
Fig. 1 shewing an elevation with part of the side wall omitted, and
Fig. 2 shewing a plan thereof.
a is a receptacle for the seed; it is provided with a tapering bottom forming a
hopper or funnel that terminates in a channel b in which a regulating-slide c is
located. In front of the outlet of the said channel there is arranged a scattering-
funnel d which is capable of being rotated by means of the shaft which is
driven by hand through the medium of the bevel-wheels g and the pair of
spur-wheels h.
In order to facilitate the flow of the seed into the rotating funnel d, the shaft ƒ
is connected with the funnel d not by straight radial arms, but by means of a bent
bridge-piece arranged at the narrowest part of the funnel. This arrangement
serves to effect a uniform scattering of the seed, which is not possible in the case
of scattering-funnels with radial arms at the widest part of the funnel, because in
such cases the arms hinder the movement of the seed.
When it is desired to scatter the seed to the greatest possible distance, the
internal surface of the funnel may be provided with a number of curved or screw
like ribs extending in the direction of the length of the funnel.
A modified construction of the apparatus is illustrated in the drawings filed
herewith. In these drawings,
Fig. 3 shows an elevation of the apparatus with a portion of the side wall broken
away; and
"
Fig. 4 shows a plan of the apparatus with a portion of the front wall broken
away and with some of the parts in dotted lines.
Figs. 5 and 6 are respectively a front elevation and an underside view, both to
an enlarged scale, of the scattering funnel or wheel detached from the remainder
of the apparatus.
Similar parts in Figs. 1 and 2 and in Figs. 3, 4, 5 and 6 are marked with similar
letters of reference.
The modified construction of my apparatus shown in Figs. 3, 4, 5 and 6 is similar
to the construction shown in Figs. 1 and 2 with the exception that in lieu of the
conical scattering funnel or wheel d of Figs. 1 and 2, there is employed a scattering-
wheel which consists of a box-like conical body d¹ provided with projecting seed
distributing channels ; and secured on the shaft in any other suitable manner as
for example by a nut k. The box-like body d' is closed on all sides except that it
is open towards the supply channel b, and that it is provided with two or more
apertures in its front wall or that which is furthest from the said supply
channel b. The seed distributing channels ; which are without internal obstructions,
are preferably triangular in cross-section, are curved after the manner of screw
propeller blades, and are arranged to extend outwardly from the apertures 1.
During the rotation of the scattering-wheel the seed issuing through the
apertures is scattered over a considerable area owing to the action of the
channels and to its not being hindered by any obstruction in such channels.
For the purpose of facilitating the entry of the seed into the channels, au
inwardly projecting rib m is provided in proximity to each of the apertures and
on the interior of the end wall of the body d', these ribs serving to catch the seed,
which shares in the rotation of the body d', and compel it to pass out through the
apertures into the channels j.
When the apparatus is constructed of considerable size it may be mounted
on wheels; in this case the shaft f may be driven from one of the travelling
wheels.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. Seed sowing-apparatus comprising a receptacle a provided with a funnel-
shaped or hopper-like bottom, a scattering funnel or wheel adapted to be rotated
by a train of wheels, and a supply channel 6 which connects the receptacle a and
the said funnel or wheel and is capable of being regulated by means of a slide c
the arrangement being such that the seed will automatically pass along the channel b
from the receptacle a to the said scattering funnel or wheel and will be sown
broadcast by the said scattering funnel or wheel substantially as described.
2. In a sowing-apparatus of the kind referred to in the preceding claim,
fastening the funnel / to the shaft by means of a curved bridge i attached to
the narrowest part of the funnel, in order to produce a uniform scattering of
the seed.
3. In seed sowing apparatus of the kind referred to in Claim 1, the modified
construction of scattering wheel d shown in Figs. 3 to 6 inclusive of the accom-
panying drawings and consisting of a hollow body d¹ provided with outwardly
extending or screw like seed distributing channels j and closed on all sides except
opposite the supply and distributing channels band j substantially as herein
described for the purpose specified.
