PROVISIONAL SPECIFICATION.
Pneumatic Tyre for Bicycle and other Vehicle Wheels.
DAVID SANDERSON, 10, Oliver Street, Portland Road, Nottingham, Bicycle
Maker, do hereby declare the nature of this invention to be as follows:
This invention relates to pneumatic tyres for bicycles & other vehicle wheels
my object is to produce a cover for pneumatic tyres in connection with which
an inner tube is used for inflating, the said cover to be made in such a manner
that it will adapt itself to any ordanary rim & be free from rusting or chafing,
to attain this I take a piece of canvas or any other fabric I may choose, of a
suitable size for the cover to be made & wrap it round a wheel or drum of
a suitable diameter then wind round it a quantity of hemp, flax, thread or other
material to form two flexible rings or skeins at equal distances from each edge
leaving double the distance between the rings for instance if the canvas is eight
inches wide I wind the hemp or other material two inches from each edge leav-
ing four inches between, I now give it all a coat of rubber solution & when
sufficiently dry fold the two outer edges over to the center pressing all well
together it is ready for the rubber or any other band I may use to be fixed,
& having no wires will not rust, & being soft & flexible will not chafe in taking
off & putting on the rim & having no hard edge will adapt itself to any ordanary
rim.

Pneumatic Tyre for Bicycle and other Vehicle Wheels.
DAVID SANDERSON, 10, Oliver Street, Portland Road, Nottingham, Bicycle
Maker, 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 relates to pneumatic tyres for bicycle & other vehicle wheels
my object is to produce a tyre that will fit any ordinary rim and at the same
time have no wires hooks or the like fastenings to rust, corrode or break to
attain this I substitute hemp, flax, thread or the like in place of the usual wires
hooks & the like. To make, I proceed as follows:-Having procured a wheel,
drum or the like of a suitable diameter & width I now take a piece of canvas or
other fabric of a suitable size for the tyre to be made & place it round the cir-
cumference of the wheel. I now proceed to wind round the canvas or fabric
which for preference I have on a revolving wheel a number of threads (about

page_text: 50 for preference) of hemp for preference to form two flexible rings, circles or
skeins, at a suitable distance apart for the width of the tyre to be made. I now
thoroughly soak with rubber solution for preference to make the threads_damp
proof, but oil, varnish or the like may be used for the same purpose. I now
give the whole one or two coats of rubber solution & when sufficiently dry I turn
the outer edges of canvas or the like to the centre leaving the rings or circles
or the like folded in at extreme edges usually occupied by wires or the like
fastenings. I now take the usual rubber cover & give it one or two coats of
rubber solution & place it on the canvas already prepared as described above in
the usual manner.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is:-
1. A pneumatic tyre that will adapt itself & fit any ordinary rim with a groove
or hollow in it regardless of the shape of groove or hollow.
2. The manner in which I use & combine the material so that it makes a
flexible & unstretchable edge to hold it in the rim.
3. The manner in which I wind the threads on or round the canvas.
DAVID SANDERSON.
