PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatic and other Tyres.
I, WALTER SANDELL MAPPIN, of Riverside, Cambridge Park, Twickenham, in
the County of Middlesex, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:
-
This invention relates to improvements in pneumatic and other tyres for bicycle
and other wheels to facilitate and simplify the affixing and detaching the same
and has reference to their construction.
In place of the rigid metalic wires now commonly used for affixing the outer
covering of the tyre to the rim I substitute a pliable wire cord or other band made
inextensible and endless which I prepare in the following manner.
The cords or bands may be made of iron, steel, alluminium or other metalic wire
or of silk, thread or twine or other suitable material, either separately or in com-
bination and consist of a metalic wire or thread alone or in combination of suitable
size and gauge being wound round several times forming a continuous circular
core, the length or circumference of the cord or band required, and of suitable
substance. A strand such as is used in making wire or other cord suitably pre-
pared is then wound spirally round the core several times until the core is com-
pletely covered, the ends of the strand are then joined together or otherwise
secured.

suitable substence, the ends are to be then joined together or otherwise secures
A strand such as is used in making wire or other cord suitably prepared is then
wound spirally round the core several times until the core is completely covered,
the ends of the strand are then joined together or otherwise secured. Previous to
