Improvements in Tension Spokes and Wheels for Vehicles.
I, CARL FICKELSCHEER, of 6, Topleumarkt, Cassel, in the Kingdom of Prussia,
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 object of my invention is an improved kind of tension spokes and wheels
for vehicles in which the rim is connected to the spokes in the manner now generally
adopted for cycle wheels. A feature of the invention is that the person driving or
riding the vehicle may make good again or repair at any time or place by means
of reserve parts carried on the vehicle, any damage or breakage happening to the
spokes whilst running.
The accompanying drawing represents a wheel fitted with the new arrangement
of spokes.
Fig. 1 is an elevation of part of a wheel provided with the improved spokes.
For the better comprehension of my invention I have shown the front spokes in full
lines and those on the other side in dotted lines.
Fig. 2 is a cross section through the wheel.
Fig. 3 shows the mode of connection of the spokes with the hub and rim on a
larger scale.
Fig. 4 shows a detail thereof in elevation.
According to this invention the spokes are for the purpose of subsequent tighten-
ing, made of a double length of wire, which is twisted as shown in Fig. 3, the free
ends of the single wires being passed through notches provided in an annular
projection of the hub and joined therein by a tubular connecting piece 6 surround-
ing them or provided with heads or enlargements for holding them in place. In
twisting the wire to form a spoke eyes care left at the ends by means of which
each spoke is attached to a nipple d. The latter may be fixed to the rim by simply
rivetting it or the countersunk head may be passed through the rim and secured
thereto by means of a nut bearing on the inner surface. Fig. 4 shows an elevation
of this nipple with a lock nut before it is fitted to the rim. A small spanner may
be used to obtain the desired tension.
-
The further twisting of the spoke wires between the hub and the rinu results
in the spokes being tightened to the required extent.
To replace a broken spoke at any place it will suffice to carry on the vehicle
a small roll of steel wire or a few ready made spokes. In case no such reserve parts
should be at hand, the arrangement of the nipples and notches in the hub permits
of a cord or the like being used in cases of necessity so that the wheel may still
be used for a short time.
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:-

page_text: of wire a the tension and consequent shortening of which is caused by twisting of
same, substantially as described.
2. In wheels having twisted wire spokes of the kind described means of fixing
the spokes to the rim and hub comprising hooks d secured to the rim to receive
eyes c formed at one of the ends of the spoke, the single wire parts of the spokes
being placed in notches provided in an annular projection of the hub and joined
therein by a tubular connection substantially as described.
3. The combination and arrangement of parts constituting the complete spoke
and means for attaching same to a wheel substantially as described or illustrated
in the accompanying drawings.
