PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of India Rubber Tyres.
I, JAMES GEORGE INGRAM of The London India Rubber Works, Felstead
Street, Hackney Wick, in the County of Middlesex, India Rubber Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The invention relates to improvements in the manufacture of india rubber tyres,
by the introduction of fibre, with a view to prevent the splitting or tearing of the
rubber which has hitherto been a great fault and weakness and which soon renders.
the tyres useless.
In introducing fibre we overcome this great fault and render the tyres more
durable and lasting by preventing them from splitting which splitting was liable to
take place before the tyre was worn out.
This introduction of fibre also tends to make the tyre wear more evenly and
therefore give greater satisfaction whilst it adds little or nothing to the expense of
production.
In carrying my invention into effect I thoroughly mix with the rubber compound
ordinarily employed a suitable proportion of fibre which will act as a bond to the
rubber compound and prevent the splitting or tearing thereof when the tyre is
vulcanized and in use.

I, JAMES GEORGE INGRAM, of The London India Rubber Works, Felstead
Street, Hackney Wick, in the County of Middlesex, India Rubber Manufacturer,
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:-
The invention relates to improvements in the manufacture of solid india rubber
tyres for carriage wheels by the introduction of fibre, with a view to prevent the
splitting or tearing of the rubber which has hitherto been a great fault and
weakness and which soon renders the tyres useless.
In introducing fibre I overcome this great fault and render the tyres more
durable and lasting by preventing them from splitting which splitting was liable to
take place before the tyre was worn out.
This introduction of fibre also tends to make the tyre wear more evenly and
therefore give greater satisfaction whilst it adds little or nothing to the expense of
production.

page_text: In carrying my invention into effect I thoroughly mix with the rubber compound
ordinarily employed any suitable proportion of fibre which will act as a bond to the
rubber. compound and prevent the splitting or tearing thereof when the tyre is
vulcanized and in use. The fibre employed may be obtained from cloth or from
waste rubber containing fibrous material or from other convenient source.
fibre is mixed with raw rubber in the ordinary masticating or mixing machines.
I vulcanize the tyres thus formed preferably in a mould.
This
I have found that the quantity of fibre employed may be one tenth in weight of
the rubber combined therewith. Other proportions of the fibre may however be
employed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
The improvements in the manufacture of india rubber tyres by the combination
of fibre with the india rubber used in their construction, substantially as herein
described.
