PROVISIONAL SPECIFICATION.
Improvements in or connected with Elastic Tyres for Cycles and
other Vehicles.
I, HENRY THOMPSON, of Trinity Street, Gainsborough, in the County of
Lincoln, Engineer, do hereby declare the nature of this invention, to be as
follows:-
The object of my invention is to provide a tyre for cycles and other vehicles
which when punctured will not collapse the tyre, the use of air under pressure
being dispensed with, and the resiliency of the tyre being substantially the same as
a pneumatic one.
According to my invention I employ cork to form the cushion between the
outside or tread of the tyre and the rim of the wheel.
The cork is arranged in suitable pieces or segments around the circumference,
and the outer covering of the tyre may be of india-rubber or other suitable
material which holds the cork and keeps it in position, the object in using cork
being to prevent the tyre collapsing should a puncture occur.
Or the cork may be secured to steel or other suitable metallic band at suitable
distances apart, or continuously throughout the band.
The said tyres are secured to wheel rims by bolts and nuts, by cementing, or in
any other suitable manner.

I, HENRY THOMPSON, of Trinity Street Gainsborough, in the County of
Lincoln, Engineer, do bereby 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 my invention is to provide a tyre for cycles and other vehicles
which when punctured will not collapse the tyre, the use of air under pressure
being dispensed with and the resiliency of the tyre being substantially the same as
a pneumatic one.
According to my invention I employ cork to form the cushion between the
outside or tread of the tyre and the rim of the wheel. The cork is arranged in
suitable pieces or segments around the circumference, or crosswise, and the outer
covering of the tyre may be of india-rubber or other suitable material which

Or the cork may be secured to a steel or other suitable metallic band at suitable
distances apart or continuously throughout the band.
The said tyres are secured to wheel rims by bolts and nuts, by cementing or in
any other suitable manner.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a sectional elevation showing segments of tyre circumferentially.
Fig. 2, is a cross section of tyre, with solid cork core.
Fig. 3, is a cross section of tyre, with hollow cork core.
Fig. 4, is a cross section of tyre, with hollow cork core and metallic band.
Fig. 5, is a cross section of tyre with solid cork core in sections crosswise.
A is the cork which may be solid or hollow and in sections around the tyre
(see Fig. 1) also when solid may be in sections crosswise (see Fig. 5), B is the
rubber tyre or outer cover, C is the metallic strip, preferably placed between the
inner periphery of the rubber tyre, and the outer periphery of the cork core and
may be found very necessary in wheels for heavy vehicles for protecting the cork.
D is the metal rim of wheel, the cover or tyre may be secured to the rim in any
suitable manner.
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. For the wheels of cycles and other vehicles the employment of solid cork
cores in segments either circumferentially or crosswise or both (for supporting the
rubber tyre or cover with or without a metallic band) substantially as shown and
described.
2. For the wheels of cycles and other vehicles the employment of hollow cork
cores in segments circumferentially (for supporting the outer tyres or covers)
substantially as shown and described.
3. For the wheels of cycles or other vehicles the employment of hollow cork
cores in segments circumferentially with the metal band (for supporting the outer
tyres or covers) substantially as shown and described.
