Improvements in Pneumatic Tyres.
SAMUEL HENRY ADAMS Hydraulic Engineer Peaseholm Green York 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 improvements consist in the provision of two or more air tubes or cases
within the covering or outer tyre of a wheel so arranged that if the inflated tube
which may be in use, becomes damaged or pierced then I am enabled to inflate
another tube which has been in disuse and by this means I have practically created
a reserve in the shape of another tube or case for inflation when necessity demands
its use.
I may form the tubes quite separately or I may form one with a
longitudinal division or divisions which shall so separate the sections that to all
intents and purposes they act as separate and distinct tubes my care being that the
air tube or case in disuse may be by preference protected by that which is inflated
and in use, as by this means I am able to guard against injury to same and to have
it in reserve and perfect ready for inflation on the failure or damage to that
inflated first. Although I prefer to arrange these tubes thus I may use them side
by side or in any desired manner. The multiplication of air tubes placed in any
desired manner being my object rather than to rely as now upon the use of one air
tube only. Reference to my drawings shews at Fig. 1. in section a single air
tube A inflated with B the valve or other contrivance through which air enters to
inflate the tube and C my tube in reserve is shewn in this instance as a distinct
tube, with the inlet for air at D. with E the felloe of wheel upon which my tubes
are placed, and in both Figs. 1 and 2 M is an outer covering. Assuming that the
tube A is pierced, it will become deflated, and I can inflate my reserve tube C.
At Fig. 2. I shew another arrangement where instead of being two distinct tubes
as in Fig. 1. I form my air tube F with a division G or divide it in such a manner
that this division is common to the outer and also to the inner tube H. At J is
the inlet for air to tube H, and at K the inlet to tube F with E the felloe of wheel
At Fig. 3. a side view of a wheel is shewn where A is an outer casing B is an
inflated tube and C is a tube deflated which will upon inflation take the place of
tube B And now
Having fully described and ascertained the nature of my said invention and in
what manner the same is to be performed what I claim is
1st. The use of an air tube being divided longitudinally and practically forming
two or more tubes or cases for air inflation.
2nd. The combination of two or more air tubes placed round the circumference
of a wheel and so arranged that upon damage or puncture to the outer tube that
beneath it may be inflated.
3rd. The arrangement of air tubes within a casing enveloping the circumference
of a wheel by which one tube when inflated shall protect that below it from damage
that the undamaged tube may be inflated for use instead of the first named.
4th. The multiplication of air tubes however formed or arranged that being placed
upon the circumference of a wheel one or other may be inflated to replace one or
other which may have become damaged in use.

described and their equivalents though differing in conformation essentially the
same and for the same purpose.
