Improvements in Pneumatic Tires.
I WILLIAM WHITE of 115 Harold Road, Upton Park, Plaistow Essex do
hereby declare the nature of this invention to be as follows:-
A tire' made in sections of any required length to fit any groove; to be made
of rubber & canvas; to be inflated by air; (either by inflating needle or valve) and
to be used with an outer covering of rubber & canvas to lace on wheel.
It is the tire that I wish to protect & which I think is an improvement upon
any in use because the 'sections' being light & small can be carried by the rider & a
fresh section put in easily & quickly in case of puncture; also in case of puncture
in an ordinary pneumatic tire' the whole tire collapses whereas in the 'improved
pneumatic tire one section only would collapse.

Improvements in Pneumatic Tires.
I, WILLIAM WHITE, of 115 Harold Road, Upton Park, in the County of Essex,
India Rubber Mechanic, 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 :-
My invention relates to an improved construction of pneumatic or air inflated
tire, and it consists in making the chamber to contain the air in a series of separate
and independent sections adapted to be placed in or on the wheel rim, end to end,
and in enclosing and covering the said sections by a suitable cover adapted to be
fixed round the wheel rim by lacing its two edges together or by attaching the said
edges of the cover to the wheel rim by any of the well-known methods, the object
being to provide for the ready repair of the tire when punctured and for the easy
replacement of the damaged section.
I attain this end in the manner shown by the accompanying drawing, in
which :-
Figure 1 is a view in transverse section of my improved tire.
Figure 2 is a similar view showing a modification in its construction, and
Figure 3 is a view in side elevation of one of the sectional air chambers.
Throughout these views similar parts are marked with like letters of reference.
Referring to the accompanying drawing A designates the wheel rim which may
be of the hollow type as shown in the drawing or of the solid type. B designates
a section of the air tube or chamber which is made of any convenient length say six
inches. The ends b, b, of these sections are bevelled or chamfered both in the same
direction so that the ends fit over and under each other respectively and there are
thus no vertical walls to offer increased resistance. Each section is fitted with
a suitable valve C for inflation and deflation. The sections may have at each end
a strip of any suitable material the ends of which are adapted to be passed round
the wheel rim A and to be secured thereto or to each other in any convenient
manner as shown by Figures 1 and 3, but their use is not obligatory. C¹ designates
the cover which is adapted to cover the section of the air tube or chamber and pass

wheel rim by means of laces, hooks or by any other equivalent device.
If the sections B are made of rubber only the cover C is reinforced with a
backing of canvas or textile fabric but if they are made of rubber aud canvas or
other textile fabric the cover may be made of rubber only.
It will be seen that with this construction of tire a puncture does not bring about
the total collapse of the whole tire, and further that as the sections of the air tube
or chamber are small spare ones can easily be carried by the rider to replace
punctured or damaged ones.
I am aware that tires have already been made with a sectional air tube in
the form of a series of air balls placed side by side in the wheel rim and enclosed
by a suitable cover, and I do not therefore claim the use of sectional air tubes
broadly, but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The herein before described combination of parts constituting a new and improved
