I, JOACHIM OLDENBURG of Carlow, Mecklenburg in the Empire of Germany,
Manufacturer 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 :-
It is well known that the air and especially wind offer to the cyclist a great
resistance, which causes considerably more exertion to the cyclist.
This invention is intended not only to avoid this loss of power but to render the
resistance of the air or the power of the wind usable as a propelling power for the
cycle.
In the annexed drawing Fig. 1 shows a cycle with the construction serving for
this purpose and Figs. 2-5 show details thereof.
On the top of the steering head is fixed the eyea of the bow H, which surrounds
loosely with its eye B the tube B 1 belonging to the framing and through which
tube piece passes the steering post of the front forks A; the horizontal part B 2
of the bow H ends at the front in a pin Fig. 5, upon which rotates the hub d of
the wind wheel D. The hub d carries besides a bevelled wheel E which gears
with a bevelled wheel E 1, the shaft of which is journalled with its upper part
in an eye of the bracket e which is connected with B2 and surrounds the tube B 1
lcosely with an eye B3; at its under part the shaft F is journalled in the
bracket e 1 which is fixed on the fork. The bevelled wheelf on the shaft F gears
with a bevelled wheel fl on the axle of the wheel G. When therefore the fork A
is turned by operating the handle bar, the wind wheel D, the bow H and the
wheels E E1,ff1 participate in this movement, the eyes B B 3 turning round the
tube B 1.
The wind wheel D (Figs. 4 and 5) consists of a peripheral crown D 1, which is
made of plate metal or wires and is connected by means of the spokes d 1 with the
hub d. The wings are formed by segmental plates D 2, one edge of which is
folded round to form a tube whereby the plates are suspended on the spokes d 1.
The swinging movement of the wings is limited on both sides by pins m.
The wind as such or also the air presses by means of the velocity of motion of
the cyclist against the wheel and turns it whereupon the movement is transferred
by means of the gear described to the axle of the cycle wheel.
As the wings d 2 are suspended movably and their movement round the spokes
is limited by the pins m on both sides, the wheel when the wind blows from the
back will turn in the same sense as when the wind blows from the front.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) An improved cycle in which the resistance of the air is used for driving a
wind wheel, the revolution of which is transferred by an appropriate gear to oue
of the cycle wheels.

wings hinged out of their centre axes on spokes and limited in their turning
movement by two projections fixed on the wheel rim on both sides of the turning
raxis.
