PROVISIONAL SPECIFICATION.
An Improvement in Pneumatic Tyres for the Wheels of Cycles and
other Vehicles.
I, ARTHUR ALEXANDER CROZIER of 43 Gibson Square, Islington, in the County
of London Engineer, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to an improvement in pneumatic tyres.
The object of the invention is to render such tyres puncture-proof without destroying
their resiliency or lessening their speed.
In carrying the invention into effect I locate, by cementing with any suitable
adhesive, a leather band, of a suitable width, formed with feather edges, between the
rubber and canvas of the under or inner part of the tread of the tyre, such leather
band is previously rolled or compressed by any suitable means, so as to form a hard,
but flexible puncture proof band, which cannot cut the rubber or deaden the tyre
like steel and other metal bands.
Such leather band may be adapted to single tube tyres, or detachable tyres.

I, ARTHUR ALEXANDER CROZIER, of 43 Gibson Square, Islington, in the County
of London, Engineer, do hereby declare the nature of the said 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 an improvement in pneumatic tyres; the object of the
invention being to render such tyres puncture proof without lessening their speed
or resiliency, or increasing their weight.
The invention is illustrated in the accompanying drawings in which :-
Fig. 1. represents a cross section of the improved tyre in the form of a detachable
tyre.
Fig. 2, represents a like view of a modification.
Fig. 3, represents a like view of the improved tyre as a single tube tyre.
In carrying the invention into effect, I locate, by cementing with any suitable
adhesive a specially prepared band a, of the material known as rawhide, between the
layers of the fabric 6, of the tyre Figs. 1 and 3, or between the rubber and fabric of
the tyre Fig. 2, such rawhide band a, being formed with widely bevelled or feather
edges a', such rawhide band being of a sufficient width to protect the whole surface
of the tyre from puncture.
I have found it necessary to gradually extract the free oil out of the rawhide
before inserting it between the rubber and fabric, or between the layers of fabric
of the tyre, so as to prevent such free oil oosing out of the rawhide in the course of

page_text: time, and acting on, and destroying the rubber of the tyre. Such rawhide band may
be relieved of such free oil by gradually sweating or heating it in a hot chamber so as
not to destroy the desired flexibility and hardness of the rawhide, or in any other
suitable manner.
By the use of such rawhide band, it is not necessary to have the rubber part of the
tyre nearly so thick as is necessary in ordinary pneumatic tyres, therefore such rawhide
does not increase the weight of the tyre.
I thus produce, by the use of such prepared rawhide band, a light resilient and
puncture-proof pneumatic tyre, such rawhide band possessing the peculiar advantages
of being very tough, but at the same time very flexible, does not deaden the tyre.
Such tyre may be made as a single tube tyre or as a detachable tyre, and connected
to the rim of the wheel in any suitable manner.
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 combination of a pneumatic tyre and a rawhide band formed with widely
bevelled or feather edges, and having its free oil extracted therefrom, such rawhide
being applied to the tyre as described and illustrated, for the purpose of preventing
puncture.
