Improvements in Tyres for Cycles.
We ROBERT STRETTON and HENRY ARTHUR NEITHERCOTT both of 23 Hindon
Street Victoria Station London S.W. Cycle Engineers and Manufacturers trading
as Stretton & Neithercott, do hereby declare the nature of this invention to be as
follows:-
The addition of a piece of solid rubber with a furrowed surface right round the
outside of an ordinary pneumatic tyre. Such piece of solid rubber being vulcanized
on the surface of the tyre or by being made with the tyre in one piece and we claim
this invention as applied to all pneumatic and other air tyres.

COMPLETE SPECIFICATION.
Improvements in Tyres for Cycles.
We ROBERT STRETTON and HENRY ARTHUR NEITHERCOTT both of 23 Hindon
Street Victoria Station, London, S. W. Cycle Engineers and Manufacturers trading
a5 "Stretton and Neithercott" do hereby declare the nature of our 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 improvements in or connected with pneumatic or other
air tyres for cycles and consists in providing the said tyres with an additional piece
of solid rubber round the periphery or bearing surface of such tyres. Such
additional piece of solid rubber may be vulcanized onto or be otherwise attached
to the surface of the tyre or it may be formed in one with the tyre by ordinary
known means.
And in order that our invention may be the better understood we have shewn in
the accompanying sheet of drawings examples of tyres constructed according to our
invention but we do not limit ourselves to the precise forms therein set forth.
Figure 1 represents in sectional elevation a portion of a pneumatic or other air
tyre A provided according to our invention with a rib or additional piece of solid
rubber B round the periphery or bearing surface of the tyre whereby the durability
of the tyre is considerably increased.
The rib B is here shewn with a grooved or furrowed surface to prevent slipping.
The rib or additional piece of solid rubber may be formed with plane surfaces
the furrows being dispensed with as shewn for example in Figure 2, A being the
tyre and B the additional piece forming the bearing surface. We do not limit
ourselves to the thickness of the bearing part B which may be varied according to
the tyre to which it is applied. Our invention is equally applicable to pneumatic
and other tyres which have already been in existence.
Pneumatic tyres made according to our invention are more durable and less
liable to punctures than are ordinary pneumatic tyres whilst owing to the small
surface in contact with the ground friction will be reduced and machines provided
with our improved tyres will be more readily propelled and with less exertion on
the part of the rider than when provided with ordinary tyres.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner. the same is to be performed we declare that what
we claim is :-
1. In pneumatic or other air tyres an additional solid rubber bearing piece either
formed therewith or applied thereto substantially as and for the purposes herein-
before described.
2. The improved pneumatic or other air tyre described and illustrated in the
accompanying drawings.
