PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres for Cycles and Carriages.
WILLIAM MERRITT 159 Malvern Road West Kilburn Omnibus Driver do hereby
declare the nature of this invention to be as follows:-
This tyre is composed of 31 air-tight sections which are filled with air from
31 valves, these valves are filled with air by a small circular tube, which passes through
into each section. When the sections are filled, the air cannot return back into the
tube again. To enable to release the air there is another circular tube fixed with
outlet valves which will not let the air out until a stopper is unscrewed out of the
tube. The object of having small sections are that when a puncture occurs in one
of the sections, the sections each side of the damaged one will fill in each side, so
enable the wheel to travel on without stopping.

Improvements in Pneumatic Tyres for Cycles
Triage
I, WILLIAM MERRITT, of 159 Malvern Road, West Kilburn, in the County of
London, Omnibus Driver, 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 improvements in pneumatic tyres for cycles and
carriages.
This tyre is composed of thirty one air tight sections which are filled with air from
thirty one (more or less) valves, these valves are filled with air by a small circular
tube, which passes through into each section. When the sections are filled, the air
cannot return back into the tube again.
The object of having small sections are that when a puncture occurs in one of the
sections, the sections each side of the damaged one will fill in each side, and so enable
the wheel to travel on without stopping.
In carrying my invention into practice as in the accompanying drawing I construct
a tubular ring and to this said tube I solder thirty one (more or less) screwed
sockets 9 and to each socket I fix a valve h with a union and connect the same to the
inside of the rim d of the wheel. In the rim d I connect to each of the valves h an
india rubber air tight section or bag c, (thirty one (more or less) around the periphery
of the rim,) each of these said bags c is protected by a piece of india rubber tube b
and canvas e. The whole of the inflated air tight sections or bags c are protected
with any well known india rubber cover a. A stop valve is attached to the ring tube f
in any suitable position for inflating the sections by an ordinary pump.
The tube is fixed in between the spokes i and the hub of a wheel, and runs
parallel with the inside of the rim d.

page_text: To inflate each bag c the valves are first opened by a key, and when sufficiently
inflated by an ordinary pump each valve h is closed by the aforesaid key.
If preferable any number of pneumatic bags c may be used in order to build up
a tyre.
Any section may be removed if punctured by unscrewing the connection k between
the valve and the rim.
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 :-
1. In pneumatic tyres, the combination of the cover a rubber tubes air tight
sections or bags c canvas e rim d tubular ring sockets g valves and connections k,
substantially as herein described and according to the accompanying drawing.
2. In pneumatic tyres for cycles and carriages, the combination of the various parts
substantially as above described in this specification for the purpose specified.
Dated this 14th day of February 1897.
