I, SALOMON FRANK, of 21, Friedberger Landstrasse, Frankfort-on-the-Main, in
the Empire of Germany, Mechanical Engineer, do hereby declare the nature of my
invention to be as follows:-
This invention relates to an improved tyre for wheels of velocipedes and other
vehicles intended for use in place of inflated or other rubber tyres, this improved
tyre being of equal elasticity and not readily liable to injury.
According to my invention I form the tyre by winding wire in coils of different
sizes round a steel or other metal tube constituting the rim of the wheel.
For example the tyre may consist of a steel tube around which a steel spring
wire. is wound so as to embrace the tube at parts with a double coil and between
these parts to surround it with coils of larger diameter. The outer periphery of
the larger coils may be surrounded by or enclosed in a cover or casing of rubber,
canvas or other suitable material.
The spokes pass through the tube and are rivetted thereto.

Improvements in Tyres for use on the Wheels of Velocipedes
and other Vehicles
I, SALOMON FRANK, of 21, Friedberger Landstrasse, Frankfort-on-the-Main, in
the Empire of Germany, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:—
This invention has for its object to provide improved tyres for the wheels of
velocipedes and other vehicles in place of inflated or other rubber tyres heretofore
employed; these improved tyres being of equal elasticity to the said inflated or
rubber tyres but not subject to injury by puncturing.
According to this invention the tyre consists of wire wound spirally round a
tube which may constitute the rim of the wheel or which may be placed in a trough
shaped rim of a wheel the said wire being wound round the said tube or rim so as
to form two or more series of coils or windings of different diameter.

page_text: Figure 1 of the accompanying drawings represents a portion of a wheel pro-
vided with a tyre constructed according to this invention and Figure 2 shews in
side elevation a whole wheel provided with a tyre according to this invention.
Figure 3 is a transverse section of the wheel.
In the drawings A represents the rim of the wheel as being of tubular shape
and which is preferably of steel. Around this tubular rim is wound according
to this invention, a wire, of springy metal such as steel, or other suitable material
of a springy nature the said steel wire or the like being wound so as to form on
the tube series of windings or coils of different diameters as shewn at BC and D.
The one set or series of coils or windings B closely surrounds the tube A, the
coils or windings C are of larger diameter, whilst the series of windings or coils D
are of a still larger diameter and constitute the tread or running surface of the
tyre. The several series of windings or coils are formed from one continuous
wire or the like the convolutions of the coils or windings B and C being situated
between the convolutions of the coils or windings D.
The whole may be surrounded by or enclosed in a cover, or casing of any
suitable material such as rubber canvas or the like. When the tube round which
the wire is coiled constitutes the rim of the wheel the spokes of the wheel may
pass transversely through the said tube and be rivetted thereto.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is ;--
1. A tyre for the wheels of velocipedes or other vehicles the said tyre being
formed by a wire or other suitable springy material wound or coiled round a tube
constituting the rim of a wheel or placed on the rim of a wheel substantially as
hereinbefore described.
2. A tyre for the wheels of velocipedes or other vehicles formed by metal wire
or other material of a springy nature wound round the rim of the wheel so as
to form a coil the convolutions of which are of different diameters the larger con-
volutions forming the tread of the tyre substantially as herein before described.
3. A tyre for the wheels of velocipedes and other vehicles constructed substan-
tially as hereinbefore described and illustrated by the accompanying drawings.
Dated this 12th day of December 1898.
