PROVISIONAL SPECIFICATION.
An Improved Tyre for Bicycles and Light Carriages..
WILLIAM COXON 64 Radford Road, Nottingham Dyer and French Cleaner
and FREDERICK EDWIN WILKINSON 25 Carringtion Street Nottingham
Commercial Traveller do hereby declare the nature of this invention to be as
follows-
Our improved tyre is made of rubber or of any of the other composition generally
used for wheel tyres, and it is applicable to bicycles, perambucots, and other light
carriages, our object being to obtain a tyre which shall give about the same case to
the rider as a pneumatic tyre but be without the same liability of being damaged.
We obtain the object of our invention by means of an inner and an outer ring of
rübber or other composition these rings being connected to each other by inter-
mediate hollow or solid pieces placed at suitable intervals. The shape of both
rings may be varied to suit different requirements and the tyre may be attached to
the wheel by pins, clips, cement or by other means.

COMPLETE SPECIFICATION.
An Improved Tyre for Bicycles and Light Carriages.
We WILLIAM COXON of 64 Radford Road Hyson Green in the Town and
County of Nottingham Dyer and FREDERICK EDWIN WILKINSON of 25
Carrington Street in the same Town and County Commercial Traveller do hereby
declare the nature of our 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 our invention is to provide a resilient tyre for velocipedes and
other light road vehicles that shall possess the advantages of a pneumatic tyre
whilst being without the same liability to damage.
In describing our invention we shall refer to the accompanying sheet of drawings
and to the figures thereon and in carrying out our said invention we form or mould
a tyre preferably of india rubber of about the usual sectional size of a pneumatic
tyre and of variously shaped section according to the class of vehicle on which it is
used for instance-
Figure 1 shews a tyre of circular section.
Figure 2 one of oval section and
Figure 3 a flat sided tyre with segmental top and bottom.
Figure 4 shews a tyre with variously shaped perforations but only one type
would be used on the same tyre.
We construct our tyre in such a manner that it represents an inner and an outer
ring of rubber concentric with each other and joined together by ribs or bars
having spaces or intervals between them as shewn by Figure 4 in which A is the
inner ring and B the outer ring C. C. C. being the spaces or intervals which may
be of any convenient or desirable shape D. D. D. E. E. E are the ribs or con-
necting portions and these may be either solid or hollow. In order to prevent dirt
resting within the spaces C. C. C. we may find it desirable to cover the faces or
sides of the tyre, or entirely surround it, with canvas rubber or like covering or
strips as shewn by F, Figure 3.

page_text: The tyre may be attached to the rim by means of cement or by pins or clips
or we may thread wires through the tyre or through portions of the canvas or
other cover if such be used.
When the ribs or portions connecting the inner and outer ring are made hollow
as shewn by dotted lines at E Figure 4 the said portions are of greater width than
when they are solid as at D.
In some cases we may find it desirable to first mould our tyre in a solid form
and then perforate it with holes transversely of various sizes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A rubber or like tyre for velocipedes or light road vehicles consisting of an
inner and an outer ring concentric with each other and joined together by solid or
hollow ribs or connections having spaces or intervals between them substantially as
hereinbefore described with reference to drawings.
2. The improved tyre for velocipedes and light road vehicles substantially as
hereinbefore described and as illustrated by the accompanying drawings.
