PROVISIONAL SPECIFICATION.
Improvements in and connected with Tyres for Cycles and
other Road Vehicles.
I, SHELDON HAROLD STUBBS, of 16 Percival Street, Longsight, Manchester,
in the County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in or connected with elastic tyres for
cycles and other road vehicles.
In carrying my improvements into effect I make my improved tyre on what
I shall call the "suspension principle." I preferably have a deep transversely
concave or grooved hollow steel or other rim, across which I stretch and suspend
a flexible band or platform of any suitable material and upon this flexible platform
I place the tyre.
My object is to obtain resilience for the tread of the wheel in quite a novel way
and to secure a resilience approximately equal to that of a pneumatic tyre
without the drawback of risk of puncture and consequent expense and trouble of
repair.
The necessary elasticity of the said platform may be obtained in several ways;
thus the platform itself may be elastic so that it may stretch and deflect on the
wheel being loaded, such elasticity being produced by using some such substance as
rubber or even some arrangement of steel springs or spring wire netting equivalent
to a spring mattress.
Another method of procuring the necessary elasticity for the platform is to make
the said platform itself of non-elastic but flexible material stretched tightly across
the concavity of the rim which in this case would be sufficiently flexible to allow
a slight closing of the concavity and consequent deflection of the platform on the
wheel being loaded. A further method of procuring elasticity of platform may be
by placing elastic cushions on the outside edges of the rim over which the platform
is stretched. Or yet again a combination of either of the methods and means
above mentioned might be employed.
Upon this elastic platform I place a tyre of any convenient kind and made of
any suitable material either hollow or solid cushion or pneumatic or any other type.
I may also confine under the platform a pneumatic or equivalent tube as an
additional but subsidiary support.
Various modes of fastening the edges of the platform to the wheel rim may be
employed as for example any of the numerous modes now adopted to fasten on
pneumatic tyres.

Improvements in and connected with Tyres for Cycles and

I, SHELDON HAROLD STUBBS, of 16 Percival Street, Longsight, Manchester,
in the County of Lancaster, 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 :-

page_text: In carrying my improvements into effect I make my improved tyre on what I

I place the tyre.

I may also confine under the platform a pneumatic or equivalent tube as an additional
but subsidiary support.
Various modes of fastening the edges of the platform to the wheel rim may
be employed as for example any of the numerous modes now adopted to fasten on
pneumatic tyres.
And in order that my invention may be fully understood and readily carried into
effect I have annexed hereunto a sheet of drawings which illustrate three modes of
applying my improvements to the rim of a wheel.
In Figure 1 of these drawings, a designates the transversely concave hollow
steel wheel rim, a¹ the turned back or grooved edges of said rim, b the flexible
platform of any suitable material, and the india rubber or other tyre, the edges
of the flexible platform b and the tyre e being gripped and held by the turned back
edges a¹ of the rim a.

In Figure 2 I show the flexible or elastic platform and tyre combined as one
piece d, and secured to a rim a by means of flaps d' which may be stitched or
otherwise connected together, as for example, overlapped and cemented, and the
joint may or may not be further protected by a covering stripe of canvas cemented
thereon.
In Figure 3 the arrangement is substantially the same as that described with
reference to Fig. 2; but in addition I employ a pneumatic tube placed inside
and between the wheel rim a and the flexible or elastic platform.
It is obvious that the pneumatic tube f might be similarly combined with either
of the alternative constructions Figs. 1 and 2.
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. Mounting a rubber tyre upon or combining it with a flexible or elastic plat-
form stretched and secured across a hollow wheel rim in order to obtain
resilience for the tread of the wheel substantially in the manner and for the purposes
specified.
2. The improved tyre constructed and arranged substantially as described with
reference to Fig. 1.
3. The improved tyre constructed and arranged substantially as described with
reference to Fig. 2.
4. The improved tyre constructed and arranged substantially as described with
reference to Fig. 3.
