PROVISIONAL SPECIFICATION.
An Improved Fabric applicable to Pneumatic Tyres and other
purposes.
I, HARRY HEATON, the younger, of Lifford Mills, Kings Norton, in th
County of Worcester, Managing Director, do hereby declare the nature of this
invention to be as follows:-
My invention relates more particularly to fabrics of mixed fibre and rubber
intended for application in the construction of pneumatic tyres, but it is als
applicable to other cases where such fabrics may be found useful.
My invention consists in producing a fabric directly from cotton fibre and rubber
without spinning or weaving.
In one method of carrying my invention into effect I take cotton fibre which has
been combed or carded to produce parallelism between the fibres of the cotton, and
I pass a continuous layer of cotton fibre so arranged between rolls or some other
contrivance serving the same purpose, and I there impregnate the cotton with
rubber in solution or rubber in a plastic form. The cotton fibre is thus imbedde:1
in rubber and when thoroughly united with the rubber it produces a fabric whic!
is inextensible in the direction of the length of the fibres while extensible in the
direction of any other angle. That is, the fabric is inextensible longitudinally, bu
extensible sideways or transversely. I construct this fabric in thin layers an:
I combine two or more of these layers to produce a fabric which has any desire !
lateral as well as longitudinal inextensibility.
In using the word "inextensible" I do not mean that the fabric-that is, the
compound fabric formed of several layers--is to be really inextensible either
longitudinally or transversely, but only that it is to be sufficiently inextensible
both longitudinally and laterally to serve the purpose of a fabric such as canvas.
I may build up my fabric of longitudinal and cross pieces crossed at right angles to
the fibres or at any other angles. I keep my fibre of the full natural length, ant
I prefer to use cotton fibre such as "Sea Island cotton," or other American
cotton, which is known to have a long staple. By my invention I obtain a fabric
which has any desired relationship between its longitudinal and lateral extensibility
without either weaving or spinning.
In carrying the invention into effect I may pass a carded cotton direct from the
carding machine to the rubber impregnating machine, but I do not bind myself to
any particular types of machines for either carding or impregnating.

1, HARRY HEATON, the younger, of Lifford Mills, Kings Norton, in the
County of Worcester Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described an
ascertained in and by the following statement :-
My invention relates more particularly to fabrics of mixed fibre and rubber

page_text: intended for application in the construction of pneumatic tyres, but it is also
applicable to other cases where such fabrics may be found useful.
My invention consists in producing a fabric directly from cotton fibre or sliver
and rubber without spinning or weaving.
In one method of carrying my invention into effect I take cotton fibre which has
been combed or carded to produce parallelism between the fibres of the cotton and
I pass a continuous layer of such cotton fibre or sliver between rolls or some other
contrivance serving the same purpose, and I there impreguate the cotton with
rubber in solution or rubber in a plastic form. The cotton fibre or sliver is thus
imbedded in rubber and when thoroughly united with the rubber it produces a
fabric which is inextensible in the direction of the length of the fibres while
extensible in the direction of any other angle. That is, the fabric is inextensible
longitudinally, but extensible sideways or transversely. I construct this fabric in
thin layers and I combine two or more of these layers to produce a fabric which
has any desired lateral as well as longitudinal inextensibility.
In using the word inextensible I do not mean that the fabric-that is the
compound fabric formed of several layers-is to be really inextensible. either
longitudinally or transversely, but only that it is to be sufficiently inextensible both
longitudinally and laterally to serve the purpose of a fabric such as canvas. I may
build up my fabric of longitudinal and cross pieces crossed at right angles to the
fibres or at any other angles. I keep my fibre of the full natural length, and
I prefer to use cotton fibre such as "Sea Island cotton" or other American cotton,
which is known to have a long staple. By my invention I obtain a fabric which
has any desired relationship between its longitudinal and lateral extensibility
without either weaving or spinning.
In carrying the invention into effect I may pass a carded cotton direct from the
carding machine to the rubber impregnating machine, but I do not bind myself to
the use of any particular types of machines for either carding or impregnating.
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.) A new fabric applicable in the construction of pneumatic tyres for wheels,
and for other purposes, consisting of a layer or layers of cotton fibre or sliver
impregnated or covered with rubber in solution or in plastic form substantially as
described.
(2.) Process for the production of a new fabric applicable in the construction of
pneumatic tyres for wheels, and for other purposes, consisting in the impregnation
or deposition of india-rubber in solution or in plastic form upon a layer or layers
of cotton fibre or sliver substantially as described.
