PROVISIONAL SPECIFICATION.
An Improved Lining for Pneumatic Tyres of Bicycles and other
Vehicles.
I ALEXANDER HAMILTON of 20 Atlantic Avenue, Belfast, Merchant do hereby
declare the nature of this invention to be as follows:-
To provide a band or lining made of linen or other material woven in a transverse
or diagonal manner so as to have the threads in the centre of same not closely
woven but, with closely woven edges which band will constitute the lining to the
outer cover used on wheels of bicycles or other vehicles the tyres of which are
inflated with air. I use a band of linen or other suitable material so woven that
when the air tube is inflated or distended the threads of such band are stretched
across the tube transversely in a diagonal manner.
The object of having the threads stretched across the tube in such transverse
manner is to give greater strength to the lining than if the threads were woven in
the ordinary manner and also resiliency and speed and also to render the threads
less liable to cut each other under the pressure of the air tube.
The threads in the centre of the band or lining are not woven but simply lie
across each other diagonally and at each edge or side of the band or lining they are
woven into cloth.

An Improved Lining for Pneumatic Tyres of Bicycles and other
Vehicles.
I, ALEXANDER HAMILTON of 20 Atlantic Avenue, Belfast, 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 :-
This invention has for its object to provide a band or lining made of linen or
other textile material woven in such a manner that whilst the threads in the centre
are not woven closely together but merely lie across each other diagonally those at
the edges are. This hand is intended to constitute the lining of the outer cover used
on wheels of bicycles or other vehicles the tyres of which are inflated with air or gas.
The band of linen or other suitable textile material is so woven, that, when the
air tube is inflated or distended, the threads of such band are stretched across
transversely in a diagonal manner.
The object of having the threads stretched across the tube in such transverse
manner is to give greater strength to the lining than if the threads were woven in
the ordinary manner, greater resiliency and speed, and also to render the threads
less liable to cut each other under the pressure of the air tube.
The annexed drawing illustrates by way of example a piece of a lining or band.

page_text: As will be seen the threads a in the centre of the band or lining are not woven
together but lie simply across each other diagonally and at each edge or side 6 of
the band or lining they are woven into cloth.
The band or lining is woven, preferably, on a harness or damask loom with a
Jacquard mechanism; or it may be woven on a dobbie loom with heddles and
Jacquard mechanism; or on any other suitable loom with Jacquard mechanism
capable of weaving the warp and weft threads together in the usual manner with,
at the same time, one or more "shires or strips running diagonally of the fabric
where the threads simply lie across each other, as at a, without being woven
together.
"
The diagonal weaving is accomplished by making the Jacquard mechanism, at
each weft shot, lift one or more warp threads on one side and drop one or more
warp threads on the other side and also keep the unwoven shire or shires parallel.
The weft is beaten up in the usual manner.
Tyre lengths or strips are made by cutting the fabric on the diagonal and
parallel to the diagonal shire or shires.
When the cloth is woven in strips or tyre lengths I leave, at the selvedges, the
narrow margins 6 of closely woven cloth which serve to overlap or pass round the
remaining wires or grappler or other fastenings of the cover.
If desired the cloth can be woven in a tubular form with the diagonal threads a
lying across each other at the centre, or tread part. The tubular bag thus formed
is used to enclose the inner air tube of a tyre.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I consider novel and desired to claim is :
A lining for pneumatic tyres so woven that the threads at a part, or parts, are
not interwoven but merely lie across each other substantially as hereinbefore
set forth.
