SPECIFICATION.
An Improved Tyre for Velocipede and similar Wheels.
1. CHARLES VERNON WILLS, of 5 Pilgrim Street, in the City and County of
London, Merchant, 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:-
My invention relates to an improved tyre for the wheels of velocipedes and other
road vehicles, and it consists of an outer casing or sheath of rubber with a compound
core of cork and rubber, preferably made up in sections, the object being reduction of
weight, increased cushioning effect, and a quicker "spring back" after the removal
pressure.
of
which
attain these objects in the manner shown by the accompanying drawing in
Figures 1 and 2 are views in longitudinal and transverse section respectively of my
improved tyre.
Figures 3 and 4, and 5 and 6, are views in longitudinal and transverse section
respectively of other forms my invention may assume, and
Figure 7 is a view in transverse section of a further modification of my invention.
Throughout the several views similar parts are marked with like letters of
reference.
Referring to Figures 1 and 2 of the accompanying drawing A designates the
rubber sheath or casing which may either be made of one uniform thickness as
shown, or of a greater thickness on the side adapted to come in contact with the
ground. B designates the cork core preferably made up in sections as shown and
having a central hole through which passes a rubber cord' C forming with the cork
the compound core.
To increase the cushioning action of the compound core I sometimes interpose
hetween the sections thereof, rubber washers D. D. as shown by Figures 3 and 5 of
the accompanying drawings, either with or without the rubber cord C. I sometimes
also substitute a flat web of rubber for the rubber cord as shown by C, Figure 7, of
the accompanying drawing and this web may be used either with or without the
washers D, D, etc.
The rubber cord C provides a convenient means of bolding the sections of cork
together during the process of casing the core with rubber, and when I dispense with
this rubber cord as in the constructions shown by Figures 5, 6, and 7 of the accom-
panying drawing, I hold the sections of the compound core together during the process
of covering or casing it with rubber by means of a light sheath or case E of rubber,
canvas, or other suitable material, as shown by the said Figures 5, 6, and 7 of the
accompanying drawing.
It will be understood that the rubber used for the parts C and, or, D of the com-
pound core are preferably made of the purest rubber, but that the outer case or

page_text: sheath A may be made of a rubber better adapted to stand wear and give greater
adhesion to the road.
I do not limit myself to the use of a tyre of any particular section, and I wish
it to be understood that I also do not limit myself to the exact details of con-
struction herein set forth and illustrated by the accompanying drawing but hold
myself at liberty to make such changes and alterations as fairly fall within the
spirit and scope of my invention.
I am aware that prior to the date of my invention tyres for cycles have been
made of rubber tubing filled, or packed, with granulated or powdered cork, and
I therefore lay no claim to such as my invention, but
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
1st. The improved tyre for the wheels of velocipedes and other road vehicles con-
structed, arranged and operating substantially as set forth.
2nd. In a tyre for the wheels of velocipedes and other similar vehicles, the com-
bination of an outer sheath or casing of rubber, and of a compound core of cork and
rubber made up in sections, as and for the purpose herein set forth.
3rd. In a tyre for the wheels of velocipedes and other road vehicles, the combination
of an outer sheath or casing of rubber, of a hollow cork core made up in sections, of a
rubber cord passing through the said cork sections, and of rubber washers inter-
posed between the cork sections, as herein described and illustrated by Figures 3 and 4
of the accompanying drawing.
4th. In a tyre for the wheels of velocipedes and other road vehicles, the combination
with an outer sheath or casing of rubber, of a hollow core of cork or other analogous
material made up in sections, and of a rubber cord passing through the said hollow
cork core, as and for the purpose herein described and illustrated by Figures 1 and 2
of the accompanying drawing.
5th. In a tyre for the wheels of velocipedes and other road vehicles, the combination
of an outer sheath or casing of rubber, of a hollow core of cork or analogous material
made up in sections, of rubber washers interposed between the cork sections, and of a
light sheath or casing of rubber, canvas, or other material, holding the said sections
and washers together, as herein described and illustrated by Figures 5 and 6 of the
accompanying drawing.
6th. In a tyre for the wheels of velocipedes and other road vehicles, the combination
of an outer case or sheath of rubber and of a compound rubber and cork core, con-
sisting of sections of cork divided longitudinally by a web or webs of rubber, as herein
described and illustrated by Figure 7 of the accompanying drawing.
