PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres for Cycles and other Vehicles.
Louis Cox of 23, Cannon Street Birmingham in the County of Warwick,
outfitter, do hereby declare the nature of this invention to be as follows:-
In my former application for a Patent No. 17146 of the year 1896, I described
an Invention of Improvements in Tyres for Cycles and other Vehicles my tyre
being constructed of leather the leather being cut in a particular manner from the
hide. The leather outer cover contained within it an india rubber or other air
tight inner tube by means of the inflation of which the tyre was held in its place
upon the rim without, any. wires or other means of fixing the same to the rim. In
the course of my experimental, work I have discovered that if the leather outer
cover is coated on the side which bears upon the ground with a thin sheet of
fudia rubber thickened or not at the thread in such a manner as to protect from
the action of moisture, the leather cover, it is not necessary to observe the re-
strictions laid down in my former specification as to the portions of the hide from
which the leather strip is cut. I find that with a leather outer cover coated as
aforesaid and an inner air tube constructed in the usual manner I can produce a
tyre which upon inflation will hold firmly within the rim without any fastening.
The inner tube is first placed within the leather cover and the two sides of the
leather cover are then sewn or laced or otherwise suitably fastened together The
outer leather cover and its enclosed inner tube are then sprung or otherwise placed
on to the rim. Upon inflation the tyre will hold firmly in its place and a highly
resilient and extremely durable tyre is thus produced.

COMPLETE SPECIFICATION.
Improvements in Pneumatic Tyres for Cycles and other Vehicles.
I, LOUIS Cox 23 Cannon Street, Birmingham in the County of Warwick
Outfitter 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.
In my former application for a patent No. 17146 of the year 1896 I described
an invention of "Improvements in Pueumatic Tyres" the tyre therein described
having a leather cover the leather being cut from the hide in a particular manner.
The Contractile action of this cover was employed to hold the tyre securely to the
rim. In the course of my experimental work I have discovered that if the leather
outer cover is coated on the side which bears upon the ground, with a thin sheet
of india rubber thickened or not at the tread so as to protect the leather cover
from the action of moisture, it is not necessary to observe the restrictions laid

page_text: down in my former specification as to the portions of the hide from which the
leather strip is cut.. I have also found that the india rubber wears better than
the leather as the latter deteriorates when exposed to the action of moisture and
the rough surface of the roads.
The leather is preferably cured with ammonia bark and alum, and in addition
rolled and steamed, thus extracting all substances of a greasy nature, and leaving
the leather very tough and pliable.. It is then cut into strips of the required
length and width: if necessary the strips may be made of two or more lengths
joined together. The rubber cover is then secured to the leather.
The edges of the cover so constructed may be detachably or non-detachably
secured together so as to enclose the inner air tube preferably in a way that will
least interfere with the contractile action and no method of securing together
the edges of the cover must be adopted which will destroy the contractile action
of the cover.
Having now particularly described and ascertained the nature of my said inven-
tien, and in what manner the same is to be performed, I declare that what I
claim is:-
A pneumatic Tyre having a cover made of leather and rubber enclosing an
inner tube and attached to the rim by the contractile action of the leather and
rubber cover the whole being combined and arranged substantially as described.
Dated this 12th day of March 1897.
