Improvements in the Manufacture of Rubber or of Articles
Composed of Rubber and other Materials Combined for
Resisting Hard Wear.
I, WILLIAM BEALE of 33 Totteridge Road Battersea in the County of Surrey
Builder and Cab Proprietor, do hereby declare the nature of this invention to be as
follows:
Rubber tyres have been very largely tried and used for the wheels of road Vehicles
(such as Hansom cabs, bicycles, tricycles &c.) and rubber has also been used or tried
for many other purposes.
Now I have found in practice that such rubber is liable to tear and wear irregularly
and has other disadvantages which render it costly and difficult to use in many cases,
and my present invention is designed to obviate as far as possible those defects or
drawbacks and to produce an article or material which will be cheaper and capable of
resisting hard wear and possessing other advantages.
For this purpose I mix or combine masticated rubber with various materials and
chemical substances in suitable proportions. The materials I find it advantageous to
employ are French or other asphalte or any other suitable bituminous materials-also
sulphur and antimony in suitable proportions, and litharge may be added if desired, and
in some cases hardwood sawdust.
The advantage of mixing or combining asphalte or bituminous materials with
rubber are that in vulcanizing the great heat causes the whole to blend and so
produces a more solid and closer grained Material, without destroying or injuriously
affecting the elasticity of the rubber.

I WILLIAM BEALE of 33 Totteridge Road Battersea in the County of Middlesex
Builder and Cab Proprietor 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 :-
Rubbor tyres have been very largely tried and used for the wheels of road vehicles
(such as hansom cabs bicycles tricycles etc.) and rubber has been tried and used for
many other purposes such as horse shoes railway buffers soles and heels for boots and
shoes.
Now I have found in practice that such rubber is liable to tear and wear irregularly
and has other disadvantages which render it costly and difficult to use in many cases
and my present invention is designed to obviate as far as possible those defects or
drawbacks and to produce an article or material which will be cheaper and capable of
resisting hard wear and possessing other advantages.
For this purpose I mix or combine masticated rubber with various materials and
chemical substances in suitable proportions.
The materials I find it advantageous to employ in suitable proportions or thereabouts
are 25 per cent. French or other asphalte or any other suitable bituminous materials
sulphur 16 per cent. antimony 5 per cent. rubber 30 per cent, and litharge 24 per cent.
and in some cases a suitable quantity of hardwood sawdust may be added.
The relative proportions of the above materials may be varied to suit the particular
article or purpose to which such combined materials are to be applied-the same being
finally vulcanized in the manner well known and practised.
The advantage of mixing or combining asphalte or bituminous materials with
rubber are that in vulcanizing the great heat causes the whole to blond and so produces
a more a more solid and close grained material without destroying or injuriously
affecting the elasticity of the rubber.
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
The improved manufacture of rubber or of articles composed of rubber and other
materials combined suitable for resisting hard wear such improved rubber compound
consisting chiefly of asphalte or bituminous materials mixed with rubber
and vulcanizing the same substantially as and for the purposes herein before
described.
