Improvements in or connected with Elastic Tyres for Cycles and other
Wheeled Vehicles.
I THOMAS EDWARD SILVESTER of No 8 Church Street in the City of Birmingham
Solicitor do hereby declare the nature of this invention to be as follows:-
This invention consists in the use of a pad protector or cushion of india rubber or
other suitable material which may be placed within or form part of the tubular
elastic tyre or may be situate between the air tube and outer case or covering and
may or may not form part of either.
Within this pad or cushion are formed one, two, or, more air tubes or channels
placed side by side round the circumference of the tread of the tyre.
Each of these tubes may be separately inflated so that the puncture of one will
not effect the others or materially interfere with the efficiency of the tyre.
The above described pad or cushion may be used with or attached to any suitable
description of tyre.

Improvements in or connected with Elastic Tyres for Cycles and other
Wheeled Vehicles.
I THOMAS EDWARD SILVESTER of No 8 Church Street in the city of Birmingham
Solicitor 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 :-

This invention consists in the use of a pad, protector or cushion of india rubber or
other suitable material which may be placed within or form part of the tubular
elastic tyre or may be situated between the air tube and outer case or covering and
may or may not form part of either.
Within this pad or cushion are formed two or more air tubes or chambers placed
side by side round the circumference of the tread of the tyre.
Each of these tubes may be simultaniously and independently inflated so that the
puncture of one will not affect the others or materially interfere with the efficiency
of the tyre.
The above described pad or cushion may be used with or attached to any suitable
description of tyre.

page_text: Referring to the accompanying sheet of drawings to assist in the description of
my invention
Fig 1 illustrates the invention applied to a pneumatic tyre with an outer case or
covering
And Fig 2 illustrates the invention applied to a single tube tyre.
A Fig 1 is a pad of india rubber.or other suitable material which may be formed
as shewn to receive tubes B to lie within, it and together with the pad extend round
the circumference of the tread of the tyre, or these tubes B may be made together
with the pad A as part thereof.
The pad A either with or without the tubes B may be attached or form part of the
outer case C or the tubes B with or without the pad A may be attached to or form
part of the inner tube D.
A¹ Fig 2 is a similar pad to A Fig 1 with the tubes B¹ separate from or forming
part of the pad A¹ which pad A¹ may form part of the single tube D¹ or lie within it
attached or not to the tread of the tyre, as desired.
To inflate each of the tubes B I connect with each one at intervals of distance a
small elastic feeding tube E being between the outer case C and the inner tube D
each tube E leading into a valve piece F which has as many arms or ducts G as there
are tubes to be fed and in the case of the tubes D and D¹ being inflatable tubes has
the ordinary centre duct G¹ also. A valve is so formed that it will shut off.
independently all the ducts G leading to the tubes E at the same time as closing the
opening at to the tube D or D₁ thus the air in any one tube is independent of
that in the others, and the puncture of one tube will therefore not materially
interfere with the efficiency of the tyre.
I make no claim to any particular method of attaching the tyres to the rim of the
wheel nor to the application of this my invention to any one particular construction
of tyre, as it may be applied to a variety of tubular elastic tyres having the main
tube inflatable or otherwise.
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
-
(1) In conjunction with or forming part of a tubular elastic tyre a pad or cushion
extending round the circumference of the tread of the tyre such pad having upon or
against its inner surface, between it and the inner or main tube of the tyre, two or
more inflatable tubes.
(2) In tubular elastic tyres having pads or cushions and inflatable tubes as
described the method of inflating the tubes by the use of a separate air tube or duct
to each tube, substantially as described.
