Improvements in Wheels for Cycles and other light Vehicles.
I, HANS PETER MADSEN, of 13 Falkoneeralleen, Copenhagen, in the Kingdom
of Denmark, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:―
As is well known, an accident of frequent occurrence to cycles is the breaking of
one or more spokes during a ride which causes great inconvenience, because before a
new spoke can be inserted it is necessary to have recourse to a repairing shop for the
purpose of having the broken parts drilled out of the rim Generally the spokes
break off close to the boss, the causes for this being the torsional moment produced
by the rotation of the boss and the resistance of the road and the nature of the
connection between the spokes and the boss, which usually consists in screwing the
spokes into the boss or securing them thereto by nuts.
Now, according to this invention, I secure the spokes to the wheel in a manner
that considerably increases their durability.
The spokes are made in pairs, each pair consisting of a single wire bent into
approximately V or other suitable form which is fastened at each en 1 to the rim in
any convenient way such as by nipples or the like. In the middle it is secured by
being passed round a rivet, a screw-bolt, a set-screw or other projection which may
be made with an annular groove to prevent injury to the wire; or the middle of the
wires may be inserted in recesses which are made in the boss in such a way as to
leave suitably rounded projections around which the wire passes. A plate may be
screwed on or otherwise fastened to the boss so as to cover the middle portions of
the wires and to secure them in the recesses. If desired, the wire may be twisted
so that two spokes of each pair cross each other.
Wheels according to this invention are suitable for perambulators and other
light vehicles as well as for cycles.
The spokes of wheels constructed in this manner will not frequently break,
because each wire forming a pair of spokes is capable of being easily displaced
around its bolt or projection so that the said spokes will always act simultaneously
and with approximately equal force. Should a spoke break however it can be
easily removed and a new one substituted for it.

I, HANS PETER MADSEN of 13 Falkoneeralleen, Copenhagen, in the Kingdon
of Denmark, 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:-
As is well known, an accident of frequent occurrence to cycles is the breaking of

page_text: one or more spokes during a ride, which causes great inconvenience, because, before
a new spoke can be inserted, it is necessary to have recourse to a repairing shop, for
the purpose of having the broken parts drilled out of the rim. Usually the spokes
break off close to the boss, the causes for this being the torsional moment produced
by the rotation of the boss and the resistance of the road and the nature of the
connection between the spokes and the boss, which usually consists in screwing the
spokes into the boss or securing them thereto by nuts.
Now, according to this invention, I secure the spokes to the wheel in a manner
that considerably increases their durability.
As shown in Fig. 1, which shows the boss and inner parts of the spokes in front
elevation, the spokes are made in pairs, each pair a' and a consisting of a single
wire bent into approximately V or it may be other suitable shape, and fastened at
each end to the rim in any convenient way such as by nipples or the like. In the
middle it is secured by being passed round a rivet or a screw-bolt b which may have
various shapes.
Fig. 2 shows once shape in which the head c forms a bearing for
the spokes without weakening these in the least degree. Figs. 3 and 4 show
respectively in elevation and section a modification in which instead of using rivets
or bolts the boss is itself formed or provided with grooves or recesses fin such a
manner that the middle of each double spoke a¹ a² lies around a rounded projection d.
When, as in the arrangement illustrated, these grooves are made of such a shape
that the spokes cross each other a comparatively large bearing surface is obtained.
A plate g either screwed on to the boss as shewn or fastened in some other suitable
way serves to prevent the spokes from slipping out of the grooves.
Wheels according to this invention are suitable for perambulators and other light
vehicles as well as for cycles.
The spokes of wheels constructed in the manner described will not be liable to
break, because each wire forming a pair of spokes is capable of being easily
displaced around its bolt or projection so that the said spokes will always act
simultaneously and with approximately equal force. Should a spoke break,
however, it can be easily removed and a new one substituted for it.
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 wheel for a cycle and other vehicle in which the spokes consist of rods or
wires cach bent at the middle part around a rivet, a screw-bolt or equivalent,
fastened to the wheel boss, or around a projection formed by a groove made in the
wheel boss itself, the outer ends of the said rods or wires being fastened to the rim
by nipples or other suitable fastenings, and the arrangement being such that each
piece of lent wire or real forms two spokes a, a, substantially as described.
2. Wheels for cycles and other vehicles having their spokes constructel and
arrangi sul tantilly a-de-erbel with reference to and shown in the accompanying
drawings.
