Improvements in or relating to Wind Motors.
I, CONRAD HOECK of Stallschreiberstrasse 10, Berlin in the German Empire,.
Engineer 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 relates to wind motors in which the automatically
adjustable surfaces presented to the wind and constituted by sails, are arranged
over a horizontal fly-wheel.
The improvements mainly consist in limiting by sliding ropes or the like the
movement of the sail surfaces supported from the masts over the fly wheel.
The arrangement is illustrated in Figures 1 and 2 of the accompanying drawing.
Some of the details, as well as the range of movement of the sails on the fly-wheel
A mould-like or concave sail,
are more fully explained in Figures 3, 4, 7 and 8.
specially suitable for the purposes mentioned, is shown in Figures 5, 54, 6, and 64.
The motor is placed on a frame or a building m as a foundation, which building
may at the same time be used as a factory or works. In the middle of the
building m Figure 2 is arranged a vertical shaft c which may be provided in well-
known manner with a brake mechanism l. On this vertical shaft is secured, above
the building, a horizontal wheel a b (Figures 1 to 4, 7 and 8), and the shaft c may
be continued above the fly-wheel as a mast e (Figure 4). The fly-wheel a carries
at one or several points upright masts i, which may, as for instance, in Figure 4, be
connected with the central mast c, and the upper ends of the masts i may be
connected with the fly-wheel a by rigging d, x, g, h, the arms of the fly-wheel
being utilised if desired. The masts i carry in well known manner upper and lower
yards s s which can freely oscillate about the masts i (Figures 1, 3, 8). These two
yards s and s (Figures 1, 3 and 8) are held at their free ends by a cord op, or the
like, passing through eyebolts k on the fly-wheel. These eyebolts k are on the
same radius as the centres of the masts i, so that, for instance in Figures 1, 2
and 3, the sail y filled by the wind pushes forward the fly-wheel and also pulls it
forward by means of the rope o p or the like. As the sails for instance I to VIII
in Figures 1, 2 and 3 swing inwards or outwards round the masts i within certain
limits, owing to the ropes, the sails can automatically come into the necessary
position according to the direction of the wind, for instance they can come from
the positions (Figure 8) ix, xi, into the positions a, rii or vice versa.
In Figures 1 and 3 a construction is shown in which 8 sails y (I to VIII) are
used. The direction of the wind is indicated by arrows W. From these two
figures it will be seen that the sails, always turning the fly-wheel in the same
direction, are freely movable, from whatever direction the wind comes, and act in a
very efficient manner, as with widely different directions of the wind nearly all the
sails are nevertheless operative, viz. in Figure 1 the sails I, III, to VIII and in
Figure 3 the sails I to VI, and VIII are in operation. It follows from this that
it is possible to work with only one sail, as the momentum of the fly-wheel a will
bring it over the dead points (II Figure 1) and (VII Figure 3). If it is desired
that the motor remain at rest, this can be attained by the use of a suitable brake-
mechanism acting on the shaft c, for instance, in Figure 2. The sails may be
reefed more or less in well known manner either during the work or when the
motor is at rest. For the purpose of suddenly taking out of action all the sails

page_text: simultaneously, the eyebolts k for the ropes op (or their equivalents) may be so
constructed, that all the sails I to VIII may be simultaneously released by one
handle and become free, so that the motor at once stops.
For better utilisation of the pressure of the wind it is advisable to make the
sails in the shape of a mould as shown in Figures 5, 54, so that the pocket y may
be formed on either side. j or j¹, Figures 6 and 64 are corresponding side
elevation and plan of a sail y yielding to the pressure of the wind W.
Rollers n may, if desired, be provided on the framework or building (Fig. 4)
upon which the fly wheel may rotate.
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. A wind motor consisting of a centrally supported horizontal sail frame or
fly-wheel, carrying sails capable of swinging round their supporting masts, and
being limited in their swinging movements by sliding ropes or the like, substantially
as described.
2. A horizontal wind motor provided with mould-shaped or concave sails
substantially as described.
3. The combination and arrangement of parts constituting a complete horizontal
wind motor substantially as described and illustrated in the drawings.
