Improvements in and relating to the Rims and Tyres of Wheeled
Vehicles.
I, JOHN HUTSON, of 1, Calverley Park Villas, Tunbridge Wells, in the County
of Kent, Designer, 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:-
In accordance with my invention I produce a combination rim and tyre, which,
while possessing all the advantages, such as resiliency, and so forth, appertaining
to pneumatic tyres, is free from the serious drawback of liability to puncture
which applies in the case of pneumatic tyres. Not only so; but, a wheel with
the improvements according to my invention, is distinguished by its extreme
lightness, structural strength and the low cost of its manufacture.
In order that the nature and objects of my said invention may the better be
understood, I will proceed to describe same aided by the accompanying sheet of
drawings hereto appended; in which, Figure 1, is a view in elevation of one half
of a wheel with the combination rim and tyre according to my improvements;
Figure 2, cross section through the rim and tyre; Figure 3 side view of a portion
of the combined rim and tyre, shewing, in position, one of the hereinafter referred
to springs. Figures 2 and 3 being drawn to an enlarged scale relatively to
Figure 1.
The device according to my invention comprises an outer rim or running tyre a,
and inner rim b. A series of springs such as c. are introduced between a and b.
Said springs are secured by studs, screws, rivets, or by other suitable means
at d to the outer rim or running tyre a; and, at similarly, to the inner rim b.
Preferably, the outer rim or running tyre a, would be of wood, compressed paper,
or other suitable material of low specific gravity; also, as shewn in the drawings,
when and if, desired, a groove is formed circumferentially in the periphery of
the tyre a, for the reception of a supplementary running tyre or tread of rubber
or other resilient material.
The inner rim 6 may either be of the same material as the outer rim or running
tyre a, or it may be of metal, say steel. It may also be used of itself as the rim-
proper or it may be adapted to an existing rim of say a velocipede, bath chair
or any other wheeled vehicle, including motor cars.
As shewn in the drawings, an equidistant space is left in the middle of and
between, each spring to allow of the insertion and securing of the spokes of the
wheel in the inner rim b; and, although not shewn in the drawings,-suitable
means may, if desired, be employed for covering the annular open space between
the two rims for the protection of the springs against the effects of the weather,
dust &c.
I wish it to be understood that I am well aware it has already been proposed to
employ certain types of springs between the rim and the running tyre of a vehicle
wheel, and therefore. I make no claim per se for the use of springs. In the
series of springs which I employ, each spring consists of one member only,

page_text: being a length of flat springy metal-say steel-bent round so as to leave a gap
at the points of junction of the two ends of the flat springy metal to and with
the wheel rim b. In the drawings, each of the springs when bent round and
secured to assumes an elongated C shape. They may however be so fitted and
fixed as to more nearly approach a circular configuration when in situ.
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
First. The combination rim and tyre for wheeled vehicles, as herein set forth
and shewn in the accompanying drawings.
Second. In devices such as those referred to in the preceding claiming clause,
the employment of springs such as c, in the manner and for the purposes all as
herein set forth.
JOHN HUTSON.
