1, JOHANN FIMMEN JANSSEN of 21 Muhlenstrasse, Kopperhorn, near Wilhelms-
haven, Germany, Gentleman, do hereby declare the nature of this invention to be
as follows.
The present invention is a wind turbine by which the win1 beyond the range of
the wind wings is led towards then by conducting blades, so that a very great
utilization of the wind is attained.
This wind turbine is shewn on the accompanying drawing.
Fig. 1 shews a sido view, partly in section, of the turbine.
Fig. 2 is a plan view.
Fig 3 a set of wings.
Fig. 4 a plate for catching or conducting the wind.
In the frame A A' which 19 stiffened by the binces h the shaft a is arranged
vertically between the points, or in other position. This shaft a carries sets of
wings arranged in a cucle, in several rows one above the other. Each of these sets
of wings consists (as shewn in Fig. 3) of four radial bars b fastened to the shaft a
fioin the ends of which bars 6 the bats c run off tangentially at the same
inclination in knee form.
At the place of junction of the bars band, the wings are atranged
tangentially to the shaft a, and the wings d in the same way at the ends of the
bars c.
By this arrangement eight wings are carried by four arms.
The sets of
wings above described are arranged, according to their number, at equal distances
upon the shaft, in such manner that the star-like position of the radial arms bas
shewn in Fig 2, is formed. By this means a steady revolution of the shaft is
attained which with any other ariangement of the arms would revolve more or less
by jerks
In order to produce any revolution at all by the wind, this must only strike one
half of the sets of wings, lying one above the other, because otherwise the foices
would be mutually counterbalanced. With the wind in the direction shewn by tho
arrows in Fig. 2, the wind must only be led in on the left or right of the centre
point of the shaft The volume of wind is therefore limited from the first.
Nevertheless, in order to conduct a very great volume of wind into the turbine,
plates or blades "" are arranged, as shewn in Fig. 2, for catching or
conducting the wind. These plates are bent in the form of an S and have also
a turn over piece y, so that they catch the wind and conduct it into the tubine,
where under lugh pressure it operates the wings.
At the lower end of the shaft a
15 a driving-pulley by which the power is further transmitted.
For regulating the turbine, plates (not shewn on the diawing) may be placed
between the walls of the frame A, which plates limit the exit of the wind.
A portion of the plates for catching the wind can also be removed, when the
wind is too strong. The number of the arms b lying in one plane may be any
desired.

I, JOHANN FIчMEN JANSSEN of 21 Muhlenstrasse, Kopper horn, near Wilhelms-
haven, Germany, Gentleman, 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 :-
The present invention is a wind turbine by which the wind beyond the range of
the wind wings is led towards them by conducting blades, so that a very great
utilization of the wind is attained.
This wind turbine is shewn on the drawing (filed with the Provisional
Application)
Fig. 1 shews a side view, partly in section, of the turbine.
Fig. 2 13 a plan view.
Fig. 3 a set of wings.
Fig. 4 a plate for catching or conducting the wind.
In a frame A A' which is stiffened by the braces h the shaft a is arranged
vertically between the points 1, or in other position. This shaft a carries sets of
wings arranged in a circle, in several rows one above the other. Each of these sets
of wings consists (as shewn in Fig. 3) of four radial bars fastened, to the shaft a
from the ends of which bars b, the bars c run off tangentially at the same inclination
in knee formı.
At the place of junction of the bars b and c, the wings e are arranged tangentially
t, the shaft a, and the wings d in the same way at the ends of the bars c. "By this
angement eight wings are carried by four arms The sets of wings above
described are arranged, according to their number, at equal distances upon the
shaft, in such manner that the star-like position of the radial aims b, as shown
in Fig. 2, is founed By this means a steady revolution of the shaft is attained
which with any other arrangement of the arms would revolve more or less
by jerks.
In order to produce any revolution at all by the wind, this must only Etrike one
half of the sets of wings, lying one above the other, because otherwise the forces
would be mutually counter balanced. With the wind in the direction shewn by the
allows in Fig. 2, the wind must only be led in on the left or night of the centre
point of the shaft. The volume of wind is therefore limited from the first.
Nevertheless, in order to conduct a very great volume of wind into the turbine,
plates or blades ƒƒƒ³ are alanged, as shewn in Fig 2, for catching or
conducting the wind These plates are bent in the form of an S, and have also a
turn over piece g, so that they catch the wind and conduct it into the turbine,
where under high pressure it operates the wings.
At the lower end of the shaft a
1s a diving-pulley by which the power is further transmitted.
For regulating the turbine, plates (uot shewn on the drawing) may be placed
between the walls of the frame A, which plates limit the exit of the wind.
A portion of the plates for catching the wind can also be removed, when the
wind is too strong. The number of the arms lying in one plane may be any
dosed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
A wind turbine having sets of wings attanged around a shaft a lying in rows one

page_text: at the knee a wing e, and at their ends a wing d, whereby a great volume of wind
18 conducted in suitablo manner against the wings, by means of plates fƒfƒ',
hent in the form of an S for conducting the wind, as described.
