PROVISIONAL SPECIFICATION.
Improvements in Wheels for Cycles and other Vehicles.
I, THOMAS WILLIAM NEWTON CRAWFORD, of 85, Brownhill Road, Catford, in
the County of Kent, do hereby declare the nature of this invention to be as
follows:-
-
According to this invention the spokes are connected to a ring surrounding
the hub an annular pneumatic chamber being interposed between the hub and
the ring. The inside of the ring and the outside of the hub are grooved or
suitably shaped to receive the pneumatic chamber and retain it in place.
In order to keep the wheel steady the spokes are carried diametrically across
the ring being fixed on the far side to it or brackets carried by it and bearing
against it on the nearer side.
The sides of the hub or the ring also carry arms or plates bearing against the
sides of the ring or hub, balls or rollers being preferably interposed.
In cases where the axle is fixed to and drives the hub the latter and the ring
are connected by pairs of links pivotted to them and to each other.

I, THOMAS WILLIAM NEWTON CRAWFORD, of 85, Brownhill Road, Catford, in
the County of Kent, 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:―
According to this invention the spokes are connected to a ring surrounding
the hub an annular pneumatic chamber being interposed between the hub and
the ring. The inside of the ring and the outside of the hub are grooved or
suitably shaped to receive the pneumatic chamber and retain it in place.
The sides of the hub or the ring also carry arms or plates bearing against the
sides of the ring or hub balls or rollers being preferably interposed.
In cases where the axle is fixed to and drives the hub the latter and the ring
are connected by pairs of links pivotted to them and to each other.
Figure 1 is a side elevation and Figure 2 a vertical section of the central part
of a wheel constructed according to this invention.
The spokes a are connected to the central tube b whilst the axle e passes through
the tube d to which the chain wheel e is fixed. f is a pneumatic chamber of annular

forms than that shown in which case the grooves or recesses in the tubes are
suitably formed to receive it.
In cases where the axle c is required to drive the wheel the tubes b and d are
flexibly connected together preferably by pairs of links gg pivotted to them and
to each other as shown. are cover-plates and j balls between them and the
tube b.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am aware that wheels with pneumatic hubs have before been proposed
and that I do not claim these broadly but what I claim is;-
1. The combination of two co-axial tubes, grooves or recesses on the inside of one
and the outside of the other and a pneumatic tube lying in these grooves or
recesses substantially as described and shown in the drawings.
2. Connecting the tubes referred to in the preceding claim by means of links
substantially as described.
3. Wheels substantially as described and shown in the drawings.
