PROVISIONAL SPECIFICATION.
Improvement in Pneumatic Tyres for Cycle and like Wheels.
I, HUGH OSWALD BLAKER, residing at No. 7 Liverpool Terrace, Worthing, Sussex,
occupation: Builder and Contractor do hereby declare the nature of this invention
to be as follows :-
The invention consists of an airtight indiarubber tube (hereafter called the outer
tube) and within this said outer tube there is to be another tube (hereafter called
the inner or reserve tube) similar, but it may be smaller than the aforesaid outer
tube. The outside of the said inner or reserve tube to be affixed or joined (to
the extent of a quarter of an inch or thereabouts) to the inside of the said outer
tube. The join (if any) to be near to where the tube adjoins or touches the rim of
the said cycle or other wheel. Each of the before mentioned tubes to have one
opening for a valve-each valve opening to be separate and distinct, that is to say,
that each valve is to have a separate and distinct connexion with its own tube
only. The valve opening to the inner or reserve tube to be slightly to one side
of or away from the centre of the rim or vice versa. So that if the outer tube be
inflated or blown out with air, no air shall be able to enter the inner or reserve tube,
and the whole to be fastened and secured in such a way that if in the event of the
said outer tube being burst and punctured or injured or torn in any way by rough
usage, the said inner or reserve tube can be inflated or blown out with air through
its own valve and can therefore take the place of and be used instead of the aforesaid
injured or punctured outer tube.

COMPLETE SPECIFICATION (AMENDED).
Improvement in Pneumatic Tyres for Cycle and like Wheels.
I, HUGH OSWALD BLAKER, 7, Liverpool Terrace Worthing, Sussex Builder and
Contractor, 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 improvement is devised to facilitate the convenience of travelling by inflated
rubber tyred wheels of vehicles and conveyances of all descriptions:-such as cycles,
motors and carriages of every sort- and is so constructed that should an inflated
rubber tyre belonging to any of the said vehicles be burst or punctured by rough
or uneven roads, my invention can be immediately brought into use, so that the
damage to the said rubber tyre is of no immediate consequence and by the application

page_text: of my invention, the wheel of the vehicle is immediately rendered serviceable again
and fit for further use.
In carrying out my invention I employ a hollow tube or tubes of rubber or other
suitable material, which are fixed to the inside of the tube which contains the
compressed air of any tyre that may he used for the wheels of cycles and other
vehicles.
The said tube or tubes may be joined in part to the inside of the tube which
contains the air, and be constructed in such a way that they will have separate
openings or ducts for a valve, apart from the valve which supplies the tube filled with
air. So that should the tube filled with air and which contains my reserve tube or
tubes be burst or punctured, iny tube or tubes can be inflated through its or their
own valves and will take the place of and be used instead of the aforesaid burst or
punctured tube. I declare that I make no claim for the invention of any tyre or tube
filled with air to be used solely as a tyre for wheels, or for any invention that may be
said to be a complete pneumatic tyre in itself.
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 :-
The employment. of a reserve tube or tubes which can be placed inside a hollow
wheel tyre as a reserve tube, or reserve tubes, & which can be inflated through
openings belonging to themselves only, and can take the place of the aforesaid wheel
tyre when rendered useless and void by a burst or puncture.
Dated this 24th day of August 1896.
HUGH OSWALD BLAKER.
