Improvements in Wheels, more particularly for Cycles.
I, HANS SCHMIDT, of Neumarkt, near Nuremberg, in the Empire of Germany,
Director, 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:-
This invention, which is shown in the accompanying drawings in which Figure 1
is a side view and Figure 2 a transverse section, has for its object an improved
arrangement of the spokes of wheels, more particularly for cycles. Such wheels
have hitherto been constructed with a broad hub having on both sides a projecting
flange from which the spokes are carried on both sides to the centre of the inner
periphery of the rim. By this construction the wheels receive a certain stability
which becomes greater the wider the two flanges of the hub are apart. Efforts
have previously been made to make a hub, or rather the distance between the
hub flanges, as narrow as possible but for reasons of stability it is not possible to
go beyond a certain limit. By the present invention however it is possible to
make the hubs, or rather the distance between the flanges of the hub, consider-
ably narrower without thereby deleteriously affecting the stability of the wheel
in any manner.
This takes place by stiffeners or stiffening pieces being arranged between the
spokes carried from the wheel rim to the two flanges of the hub, which stiffening
pieces have the action of causing the spokes to extend not in a direct straight
line but in a bent line.
In the accompanying drawings, a ring is employed for the said object and
arranged concentrically to the hub as an example. The spokes here run from the
hub to the ring e in parallel planes to one another, and from the ring c con-
verge on both sides again to the centre of the rim a so that the spokes are thus
bent by the ring c at the points e.
The same object may of course be attained if, instead of the ring, struts or
stays be inserted between the separate spokes or any suitable device at the points
of intersection. The spokes have the same inclination starting from the rim
as they have in the ordinary broader hubs. The position of shown in dotted lines
indicates the usual width of broad hub and how the spokes have hitherto been
carried from such hubs to the rim. As in the present invention the spokes b
have the same inclination from the rim up to the ring e as they have hitherto
had, the result is that the wheel in spite of the narrow hub has quite as much
stability as in the wheels hitherto in use.
The practical advantages of the narrow hub are very important. Among the
most prominent may be mentioned that in cycling the bearing of the pedal cranks
may be narrower and the pedalling thereon take place in an exact vertical
direction.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;-
-
An outermant of coating in whole non nortionlarly for ovalus ohavastorized

page_text: by a ring (c) or other stiffening device of suitable form being arranged concen-
trically to the hub (d) between the spokes connecting the rim (a) to the two flanges
of the hub, whereby the spokes (6) carried from the rim (a) to the flanges of the
hub (b) are bent by the ring (c) at the points of intersection (e) and thus the spokes
extend in bent lines so that the wheel with an inclination of spokes similar to what
they would have if the ring (c) were not inserted has a considerably narrower hub
and yet possesses equal stability, substantially as herein before described.
