We GASTON HERVIEU of 73 Cambridge Road, Hammersmith Engineer and
GUSTAV SCHREINER of 4 Adie Road, Hammersmith, Watch Maker both in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the better securing of the air tube of pneumatic
tyres so as to prevent them from getting over the edge of the rim.
According to this invention instead of having a canvas bag to enclose the air
tube we cement or otherwise suitably fasten round the inner surface of the rim of
the wheel a strip of canvas or other suitable material so as to leave a loose flap to
fold round the air tube the said flap being held in position by the said air tube
when inflated.

An Improvement in or relating to Pneumatic Tyres.
We GASTON HERVIEU of 73 Cambridge Road, Hammersmith Engineer and
GUSTAV SCHREINER of 4 Adie Road, Hammersmith Watch Maker both in the
County of Middlesex 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 has for its object the better securing and protecting of the air
tube of pneumatic tyres in order to prevent them from getting damaged by the
edge of the rim of wheel as is now frequently the case.
In carrying our invention into effect we solution or otherwise suitably fasten to
the concave or inner side of the rim of the wheel one edge of a strip of canvas or
other suitable material so as to leave a loose flap to fold round the tyre the said
flap being held in position by the pressure of the air tube when inflated.
And in order to explain our said invention more fully we will describe the same
with reference to the drawings accompanying this Specification which shews a
section through a tyre with our improvement adopted thereto.
a shews the air tube b rim of wheel c flap of canvas or other suitable material
fastened by solution or otherwise to the rim b so that the loose portion or flap c
may wrap round the air tube a, as shewn in the drawing so that the double thickness
of canvas may be chiefly on the rim and this is kept in position by the pressure of
the air tube a when this is inflated.
The lines d shew the loose flap c as it would appear before being wrapped round
the air tube a.
It will be found that according to our invention the resiliency of the tyre is not
lessened.
The outer covering comes over the flap and may be fixed by any known
means to the rim this is not shewn on the drawing as it forms no part of this
invention.

page_text: Of course the flap c may be made broader or narrower as desired, but we prefer
it to extend round the air tube a about as shewn on the drawing.
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 :-
The flap fastened at one edge to the rim of the wheel so as to envelope the air
tube a substantially as set forth.
