Improvements in Wheels for Cycles and other Vehicles.
I, EDMUND NOBEL of 12 Badenerstrasse Zürich, Switzerland, Blacksmith 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 we know, great efforts are made by cycle manufacturers to deaden the shocks
resulting from the unevenness of the road in such a way that the cyclist might feel
nothing from them. For this purpose, the object of the present invention consists of
an elastic wheel, the tire of which gives way to the obstacles that are in its way and
consequently passes softly over them, without in the least being prevented from doing
so by the spokes of the wheel, which are of a special kind.
In the drawing which illustrates my invention,
Fig. 1 shows a view of my wheel, with the tyre partly in section.
Fig. 2 shows a front view of same with a section according to x-x of Fig. 1.
Fig. 3 shows a transverse section of one half of the wheel.
Fig. 4 shows a section according to -z of Fig. 3.
This wheel may preserve the shape and size of any other wheel, and owing to the
favourable arrangement of the spokes at the collar of the hub, it is not necessary to
modify the brackets or the frame.
The tire of this wheel is composed of one or more steel wire rings a hard-hammered
in juxtaposition, upon which are fixed the eyelets 6 to suspend the spokes; also of a
layer of rubber d, rather hardened, completely surrounding this ring & and having
about six times its thickness; this layer is placed near the exterior so that the outside
periphery of the ring a is in the centre of it.
The eyelets b (Figs. 2 & 3) are arranged in a suitable way in the direction of the
hub-collars e, so that they are alternatively inclined to the right and left, so as to
operate a more favourable tension of the tire.
The spokes c for this wheel are composed of several rather thin wires twisted into
one wire or cable by means of a key or a tension peg ƒ (Figs. 3 & 4), when the wires
necessary for this purpose have been passed through the eyelets b (Fig. 3) and
suspended with their other extremity in the screws e' of the collars e it is evident that
such a tension peg must be placed in each spoke c and hooked to the opposite spoke
by means of the elastic eyelet that this extremity presents (Figs. 3 & 4), or the tension
pegs of a suitable form destined for two opposite spokes, may be joined together in
a suitable way to prevent the spokes from untwisting of their own accord.
The arrangement of these spokes in twisted steel-wire, owing to their shortening
by twisting and to their great elasticity, allow a more favourable tension of the tire
than with massive spokes and owing to their flexibility no resistance is offered to the
tire which bends inwardly when passing over a stone or the like. Through the
elasticity of the steel-wire ring, the bent part in the inside of tire will immediately
resume its original shape after passing over the obstacle. Moreover, owing to the
arrangement of these spokes the cyclist may constantly take with him several
steel-wires to substitute in case of breakage and to stretch them immediately.

page_text: The rubber circle d which completely surrounds the steel-wire ring a can never
get loose from this latter.
This wheel can be used with cycles of any kind and with other vehicles.
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
1. An elastic wheel distinguished by one or more metallic rings a forming the tire
and completely surrounded by a rubber ring d to which rings are directly attached
spokes c which can be stretched after being fixed with the object of obtaining a great
flexibility of the tire and to easily stretch it.
2. A mode of execution of the wheel claimed in 1, in which the spokes are
composed of several steel-wires which can be twisted by means of pegs f put
through the spokes.
3. A wheel for cycles and other vehicles substantially as described above and shown
in the annexed drawing.
