PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres.
We JEAN RÉMY and MICHEL RÉMY Contractors, both of Rue Vendome,
Lyon, in the Republic of France, do hereby declare the nature of this invention to
be as follows:-
This invention for improvements in pneumatic tyres has for it object to reduce
the inconvenience caused by the perforation of the tyres when in use to a minimum;
and consists essentially in constructing the tyre in sections which are separately
secured to the rim of the wheel. The different sections are inflated simultaneously
by means of a tube extending round the rim and connected to the different sections
by small pipes and valves which open inwardly to the section. It will thus be seen
that when any section is perforated it will not affect the other sections, the air
being retained in each section by its valve and that the only inconvenience will be a
small flat in the wheel; the size of the said flat can be reduced by increasing the
number of sections. The wheel can be used with one or more perforated sections
which can be repaired at leisure.

COMPLETE SPECIFICATION.
Improvements in Pneumatic Tyres.
We JEAN RÉMY and MICHEL RÉMY Contractors, both of Rue Vendome,
Lyon, in the Republic of France, 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 for improvements in pneumatic tyres has for its object to reduce
the inconvenience caused by the perforation of the tyres when in use to a minimum;
and consists essentially in constructing the tyre in sections which are separately
secured to the rim of the wheel. The different sections are inflated simultaneously
by means of a tube extending round the rim and connected to the different sections
by small pipes and valves which open inwardly to the section.
It will thus be seen that when any section is perforated it will not affect the
other sections, the air being retained in each section by its valve and that the only
inconvenience will be a small flat in the wheel; the size of the said flat can be
reduced by increasing the number of sections. The wheel can be used with one or
more perforated sections which can be repaired at leisure.
In the accompanying sheet of illustrative drawings:
Figure 1 is a longitudinal section of a pneumatic tyre constructed according to
this invention. Figure 2 is a similar view showing a modified construction and
Figure 3 is a cross section of the same.
Referring to Figure 1 the rubber tube a is divided by a number of partitions b
into a series of chambers c. Each chamber c is connected by a small tube provided
with a valve opening inwards to the chamber to a tube extending round the wheel
to which the tyre is applied and provided with small tubes corresponding to the
small tubes connected to the chambers. The chambers can thus be all inflated at
one operation and if one be perforated it will not affect the others.
In a modification the tyre is formed of a series of separate chambers instead of
being formed of a tube divided by partitions into separate chambers.

page_text: Referring to Figures 2 and 3, the tyre is formed of a series of balls d joined at
their bases by small tubes e and covered by a cover tyre or tread f. A clip g is
arranged to act upon each tube e. When the tyre is inflated in the ordinary manner
the nuts h are screwed on the rods of the clips and close the small tubes e.
rods pass through holes m in the cover or tread f and hold it firmly in place.
In a modification the balls d are replaced by a small tube which can be closed at
suitable intervals by means of the clips g.
The
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. A pneumatic tyre formed of a series of independent sections adapted to be
inflated together, the whole substantially as described.
2. Pneumatic tyres constructed substantially as described with reference to the
drawings.
