PROVISIONAL SPECIFICATION.
Improvements in connection with Pneumatic Tyres for the Wheels
of Cycles and other Vehicles.
I, JOHN MASSEY WALKER of No. 19 Golden Hillock Road Small Heath
near Birmingham in the County of Warwick Box Maker, do hereby declare the
nature of this invention to be as follows :-
This invention relates to new and improved means of manufacturing pneumatic
tyres whereby all puncturing of the outside rubber cover is obviated by a method
of strengthening that part without in any way detracting from the resiliency of
the same.
This effect by inserting in any suitable manner within the rubber
outside cover of the pneumatic tyre a strip or layer of celluloid (preferably) of
any convenient width which may be embedded in the thickness of rubber or
solutioned on to same or sometimes may be attached to the inside or outside of
the canvas jacket of the pneumatic air chamber.
Although I have named celluloid as the material I propose to employ for
strengthening, yet I may use any other suitable substance for the purpose that
will effectually resist puncturing.
By my improved method whilst all the advantages of the pneumatic tyre are
retained other advantages of an important nature are added, liability to puncture
is reduced to a minimum and I am enabled to very considerably reduce the
thickness of rubber cover usually required thus very materially lessening the
weight as will be readily understood.
My invention may be equally applicable to what are known as single tube tyres
by moulding the tyres to the required shape out of one piece of rubber with the
celluloid or other strengthening medium inserted and embedded therein.

Improvements in connection with Pneumatic Tyres for the Wheels
of Cycles and other Vehicles.
I, JOHN MASSEY WALKER of No. 19 Golden Hillock Road Small Heath near
Birmingham in the County of Warwick Box Maker, 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 reference being had to
the accompanying sheet of drawings in which similar letters relate to similar
parts:-
My invention relates to new and improved means of manufacturing pneumatic
tyres and whereby puncturing of the outside rubber cover and the air chamber
within the same is obviated or minimized very considerably by a method of
strengthening the part that comes in immediate contact with the road without in
any way detracting from the resiliency of the tyre.

page_text: In Figure 1 of the drawings I illustrate my improved tyre in section and as it
will appear when inflated.
Figure 2 represents a sectional view of the outer covering of the tyre when
deflated.
It will be observed that I effect my improvements by attaching the usual canvas
jacket or lining, dotted lines A. of the pneumatic air chamber B. to the outside
rubber B by means of solution or otherwise, this canvas jacket or lining is
continued from the points D on each side of the rubber covering of the tyre so as
to form a double thickness, or a second thickness of canvas or other material
dotted lines A' may be attached at those points and which is folded or laid back
so that it may lie against the canvas A. To this second portion of canvas A¹
I attach in any convenient manner a strip or layer of leather E. of suitable width
and thickness in the centre of same and on the inside preferably viz. the side next
to the canvas A. of the outer rubber B¹
The outer rubber of the tyre is provided with side wires F. or other means for
securely holding the same within the rim G. when inflated as seen in Figure 1.
In my Provisional Specification I have mentioned celluloid as a material for the
strengthening of the tyre, or other suitable substance, but I prefer to use a strip
of leather as herein described or other flexible yet tough material which will more
effectually fulfil the object that I have in view for the purpose of strengthening
and resisting puncturing.
By my improved method whilst all the advantages of the pneumatic tyre are
retained I am enabled to very considerably reduce the thickness of the outside
rubber cover thus very materially lessening the weight as will be readily
understood.
The means for strengthening may with equal effect be applied to what are known
as single tube tyres, the leather or other strip or layer being suitably attached
therein behind that part where the rubber bears upon the road and will act in a
similar manner as already described with reference to those tyres having pneumatic
air chambers.
I do not confine myself to the precise method of applying my improvements or
carrying the same into effect as herein set forth as I may require to somewhat vary
the same in certain cases without departing from the general principle of my
invention, but
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is.
Firstly. In pneumatic tyres the application and use of a double thickness of
canvas or other suitable lining folded so that each thickness of canvas lies the one
against the other, and the application combination and use of a strip or layer of
leather or other suitable material attached to the said canvas in manner and for
the purpose substantially as set forth described and illustrated.
Secondly. In single tube tyres the application and use of a strip or layer of
leather or other suitable material attached therein for strengthening the same in
manner set forth and described.
Thirdly. The new or improved arrangements for strengthening and protecting
tyres from damage by puncturing in or after the manner berein set forth.
