PERCY HUTSON, Jeweller, High Street, Woodford Green, Essex, do hereby declare
the nature of this invention to be as follows:-
Improvement in detachable pneumatic tyres, consisting of a separate band of metal
or other material, with the edges turned over outwards or inwards forming a flange to
hold the edges of the outer cover of tyre which will book on to the band.
The band will be fitted in the centre of the rim of wheel, the ends to be joined
either by hooking together, screwed to the rim or other mode of fastening.
The flanges on the edge of the outer cover to be made in one, two or more sections
as required or thought necessary.
Improved Detachable Pneumatic Tyre.
I, PERCY HUTSON, of High Street, Woodford Green, Essex, Jeweller, 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:-
The object of the present invention is to construct a readily detachable pneumatio
tyre which may be fitted to practically any rim at present in use.
My invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a section of the tyre and of a well known form of rim.
inner air tube is not shown, for the sake of clearness.
.
Fig. 2 is an enlarged view of part of Fig. 1.
• Fig. 3 18 a sectional view of the outer cover,
and
In this figure the
Fig. 4 18 a sectional view of the band or holding means by which the outer cover is
held on the rim.
Fig. 5 is a side view of part of the said band or holding means, and
Fig. 6 is a plan of part of the band or holding means where the two ends overlap.
The outer cover is formed of a strip of indiarubber a, lined with canvas or other
Buitable fabric b in the usual manner. To each edge of the lining b is attached, in
any convenient manner, a strip c of metal or other suitable material, having its edge
turned inwards and upwards, thus forming a gripping edge or continuous hook.
These edges may be cut into sections so that they are extensible, thus enabling the
outer cover to be readily removed from the rim; or the gripping edges e may be made
extensible in any other convenient manner.

page_text: The band d is formed to fit the bottom of the rim, and has its edges turned over in
the form of a hook, so that they may engage with the hook shaped edges of the outer
cover This band d may be made entirely of thin metal, or it may consist of two
metal strips attached to a cental strip of canvas, leather, or like material. In
Fige. 5 and 8 I have shown the band d with splits d¹ in its edges and longitudinal
splits d', so as to make the edges thereof more flexible, but it will be understood that
the band may be rolled into a circular form and be made without any splits. In
Fig. 6 I have shown one method of connecting the ends of the band d, each portion
being partly cut away so that only the small portions d³ of each end overlap. Each
of these portions d is formed with a hole d for the valve, which latter securely
retains the band d in position on the rim e. The ends of the band d may be otherwise
connected together, or the band may be screwed or fastened to the rim in any other
suitable manner.
In Fig. 2 it will be seen that the metal edge o 18 secured to the canvas lining b
by means of stitching c¹, but other means may be adopted.
When the inner tube is inflated, it will press the sides of the band-d outwards,
and consequently the strips c and edges of the outer cover in close contact with the
sides of the rim e, thus preventing the entrance of water or dirt.
It will be understood that, although the strips c are shown turning inwards, and
the edges of the band d are shown turning outwards, the direction of these parts may
be reversed, that is to say, the strips o may be turned outwards and the edges of the
band d may be turned inwards.
When the tyre is deflated, the edges of the strip d will spring slightly inwards,
when the edges of the outer cover may he readily unhooked!
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 a pneumatic tyre, the combination of an inner air tube, an outer cover having
its edges bent back upon itself, and a retaining band having its edges bent over to
engage with the edges of the outer cover and fitting within the rim, substantially as
herein shown and described.
2. A pneumatic tyre having an inner air tube, an outer cover consisting of a
running surface lined with a suitable fabrio and carrying at its edges hook-like strips
to engage with a retaining band having its edges of hook form to engage with the
edges of the outer cover, said retaining band being located in and attached to a rim
or felloe, substantially as herein shown and described
