Improvements in Elastic Tyres for Cycles, Motor Cars, and other
Vehicles.
I, FRANZ CARL VETTERLING, of Jahnstrasse 8, Wiesbaden, in the Empire of
Gerinany, Machine Maker, do hereby declare the nature of this invention to be as
follows:---
My invention relates to improvements in elastic tyres for cycles, motor ears, and
other vehicles.
In carrying my improvements into effect I employ a tyre made wholly or partly
of india rubber of channel section or other suitable section adapted to fit over a
rim of corresponding section. Inside the tyre at the back or inner surface of the
trend I place a ring shaped backing or re-inforce consisting of a closely coiled
wire and I support this coiled wire ring upon a series of radial coiled springs each
of which is compressed between a metal washer or its equivalent bearing against
the coiled wire ring and a nut or the like serewed into the rim.
When weight is put on the tyre the tread is pressed more or less inwards and
the springs yielding, the sides of the tyre more or less overlap the sides of the rim
and owing to the formation of the coiled wire ring the tyre will readily adapt itself
to any inequalities of the road, small stones, etc., with very little expansion side-
wise. To adjust the tension of the tyre it is only necessary to slacken or tighten
the nuts and so regulate the radial springs as required.

Improvements in Elastic Tyres for Cycles, Motor Cars, and other
Vehicles.
I, FRANZ CARI. VETTERLING, of Jahnstrasse 8, Wiesbaden, in the Empire of
Germany, Machine Maker, 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:--
My invention relates to improvements in tyres for cycles, motor cars, and other
vehicles.
In carrying my improvements into effect I employ a tyre made wholly or partly
of india rubber of channel section or other suitable section adapted to fit over a
rim of corresponding section. Inside the tyre at the back or inner surface of the
[Price 8d.l

wire and I support this coiled wire ring upon a series of radial coiled springs each
of which is compressed between a metal washer or its equivalent bearing against
the coiled wire ring and a nut or the like screwed into the rim.
In the accompanying Sheet of Drawings--
Fig. 1 is a side sectional view of part of a wheel rim fitted with an elastic tyre
made according to my Invention, Fig. 2 is a transverse section of the same, and
Fig. 3 is an enlarged view of part of Fig. 2.

In Figs. 1 and 2, a designates the boss of the wheel and the spokes secured
at their outer ends to a metal rim e preferably of a channel section on which is
fitted an india rubber or other suitable elastic tyre d of channel section or other
suitable section, adapted to fit over the metal rim c. Inside the tyre at the back
or inner surface of the tread I place a ring shaped backing or re-inforce consisting
of a closely coiled wire e and I support this coiled wire ring upon a series of
radial coiled springs f each of which is compressed between a metal washer g or
its equivalent bearing against a coiled wire e and a nut h screwed into a hole made
to receive it in the rim c and holes h¹ or their equivalents are made in each nut h
to receive a key or wrench for adjustment.
When weight is put on the tyre the tread is pressed more or less inward and the
springs yielding, the sides will more or less overlap the sides of the rim c and
Owing to the formation of the coiled wire ring e the tyre will readily adapt itself
to any inequalities of the road, small stones etc., with very little expansion side-
ways. Again, as the sides of the tyre fit closely over the sides of the rim c there
will be very little, if any, opportunity, for dirt to enter the cavity between c and d.
To adjust the tension of the tyre it is only necessary to turn the nuts h or any
of them as required and so regulate the radial springs f. In addition to this,
when the springs f become defective, they can be easily renewed and the whole
arrangement is so simple that the parts can be readily taken to pieces for cleaning
or other purposes and as readily replaced.
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 ;-
1. In an elastic tyre for cycles, motor cars and other vehicles, the combination
with a metal rim of suitable section and an india rubber or other elastic tyre of
channel or other suitable section fitted over the rim, of a coiled wire ring shaped
backing or re-inforce supported on adjustable springs placed between the coiled
wire and the rim of the wheel substantially as and for the purposes described.
2. The general combination and arrangement of parts embodying my improve.
ments in elastic tyres substantially as herein described and as illustrated by the
accompanying Drawings.
