1. GEORGE LINDSEY of 26; Lordship Lane, Wood Green, London, N. Salesman
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:-.
.
This invention relates to certain improvements in tyres for bicycles tricycles.
and such like or other vehicles where resiliency is desired in the tyre of the
wheel.
Solid-rubber-tyres and pneumatic-tyres present certain practical defects, the one
for instance is liable to be cut or "sheared" and the other is liable to puncture and
deflation.
Again hollow tyres have been proposed the same being packed with a core or
inside packing of various forms and material. Metal springs tend to cut the tubular
tyre or cover; other packings become crushed and the tyres flatten or become "hard
set" which defeats the maintenance of the desired object.
In some cases it has been proposed to combine a packing core to a hollow
(tubular or otherwise) tyre and to reinforce or combine with such packing
pueumatic inflation, so as to utilize and secure the advantages of the pneumatic
tyre whilst the same is sound but so that in case of puncture the packing will
nevertheless maintain the tyre in condition sufficiently reinforced to be effective for
riding purposes or continuance of a journey.
The object of this invention is to provide a core or packing for hollow flexible
tyres which shall afford effective resilience and maintenance of resistance in
combination with the india rubber or flexible tube or tubular core covering which
will together constitute the tyre whatever may be the method or means of securing
or attachment thereof to the felloe or metal rim of the wheel.
The invention consists in the combination of strands, or cords of india rubber
with a body substance with which the said strands or cords (square, circular or
poloyonal in cross section) may be intertwined, looped passed through, and overlaid
to loop twine or kink and form the core or packing for the tyre.
The india rubber strands are to lie so intertwined, passed through and overlaid
as aforesaid that the external surface of the core when ready for insertion in the
For this purpose
covering shall present a fairly uniform outer surface of rubber.
the core so made may be overlaid with or have coiled around same continuously a
strand or strands of rubber or other material.
With the strands of india rubber as before described, I employ sponge as the
so called body substance which whilst readily allowing of the threading or passing
there-through and there-through and about for entwining the rubber strands will
nevertheless under pressure afford support and a certain elasticity.
The so called body substance instead of being of sponge may be of horse hair
which would be brought up to the form of a rope substantially and the india
.rubber strands would then be intertwined and be bound up to form the core or
packing.
The drawing annexed bereto is a diagramatic illustrative sketch representative
of a section of a tubelar tyre of india rubber with packing a such as described of
sponge and india-rubber strands combined.

page_text: The packed tyre tube A is shewn is cross section at A' and at B, the tube is
represented as being cut for a certain distance in its length and laid open to disclose
the packing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is
First. In hollow tyres for bicycles, tricycles or other vehicles a packing or core
of strands or cords of india-rubber with a body substance as and for the purpose
herein set forth.
Second. In holiow tyres, for wheels substantially as herein set forth a packing or
core of strands or cords of india rubber combined with sponge substantially as and
for the purpose herein set forth.
Third. In hollow tyres for wheels substantially as herein set forth a packing or
core of strands or cords of india rubber combined with horse hair substantially as
and for the purpose specified.
