PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Pneumatic Tyres.
I, FRANK RUSSELL HUDSON, of 61, Chancery Lane, in the County of
Middlesex, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved manufacture of woven fabric for confining
the air-tube in a pneumatic tyre.
In the woven fabric most commonly used in the construction of pneumatic tyres,
the warp threads run longitudinally round the tyre, the weft threads passing from
side to side; all the threads being of fibrous material. The warp threads, running
longitudinally and being practically unextendible, serve to distribute the impression
made by an obstacle over a considerable surface of the tyre, whereas the effect of
contact with an obstacle should be localized as much as possible.
My improved fabric is produced by employing threads or filaments of an elastic
substance, such as india-rubber, for the warp, and fibrous or unextendible threads
for the weft. The india-rubber tread may be solutioned or vulcanized to the fabric
thus formed of mixed elastic and fibrous or unextendible threads.
The warp
threads at each side of the tyre, where mechanical fastenings for securing the tyre
are used, may, if preferred, be made of fibrous or unextendible material.
On account of the elasticity of the warp threads in the improved fabric, the
impression in the tyre caused by an obstacle is practically confined to that part of
the tyre in contact with the obstacle.
Dated the 9th day of November 1893.

Improvements in the Manufacture of Pneumatic Tyres.
I, FRANK RUSSELL HUDSON, of 61, Chancery Lane, in the County of
Middlesex, Gentleman, 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 an improved manufacture of woven fabric for confining
the air-tube in a pneumatic tyre.
In the woven fabric most commonly used in the construction of pneumatic tyres,
the
warp threads run longitudinally round the tyre, the weft threads passing from

My improved fabric is produced by employing threads or filaments of an elastic
substance, such as india-rubber, for the warp, and fibrous or unextendible threads
for the weft. The tread, which is of an elastic substance, such as india-rubber,
may be solutioned or vulcanized to the fabric thus formed of mixed elastic and
fibrous or unextendible threads. The warp threads at each side of the tyre, where
mechanical fastenings such as endless wires for securing the tyre are used, may,
preferred, be made of fibrous or unextendible material.

page_text: On account of the elasticity of the warp threads in the improved fabric, the
impression in the tyre caused by an obstacle is practically confined to that part of
the tyre in contact with the obstacle.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
1. In a cover for a pneumatic tyre, the employment, substantially as herein
described, of threads of an elastic substance, such as india-rubber, for binding
together threads of fibrous restraining material reaching from side to side of the
cover.
2. For confining the air-tube in a pneumatic tyre, a woven fabric having threads
of an elastic substance, such as india-rubber, in the warp and fibrous or unex-
tendible threads in the weft.
.
3. For confining the air-tube in a pneumatic tyre secured to a rim by endless
wires or other mechanical fastenings, the improved manufacture of woven fabric
having fibrous or unextendible threads in the weft, and warp threads of fibrous or
unextendible material at the sides, the remainder of the warp threads being of an
elastic substance, such as india-rubber.
4. In a pneumatic tyre, a confining fabric having threads of an elastic substance,
such as india-rubber, in the warp and fibrous or unextendible threads in the weft,
and a tread of an elastic substance, such as india-rubber, solutioned to said
confining fabric.
