Warwick. "IMPROVED METHOD OF AND MEANS FOR SECURING OR FASTENING
ELASTIC TYRES TO VELOCIPEDE OR OTHER LIKE WHEELS."
Various modes (more or less unsatisfactory) are at present in vogue for securing
or fastening rubber tyres to velocipede or other wheels, such as by cementing the
rubber directly to the felloe or by vulcanizing other material to the rubber and
cementing this, or by passing a longitudinal wire through a hollow tyre round the
felloe and making a joint with its ends, no solid bottom being obtained to prevent
its being bent; or by using special rubber to fit a special section of tyre, thus
involving additional expense.
Elastic tyres merely cemented to the felloe are nearly always liable to come off,
while if fastened by wire (jointed as before described) this is liable to break
at the joint, as it is twisted more or less in that part touching the ground, there
being no solid bottom provided for it, besides crippling part of the elasticity of the
tyre.
Now my Invention is designed to obviate these evils, and to give a means of
easily, cheaply, and satisfactorily securing elastic tyres to ordinary rims.
It consists in making the tyre with a longitudinal groove on its inner
periphery, and over the space so formed vulcanizing a strip of cloth or other
strong material.
A wire (or wires) is passed through said groove and bent round the rim of
the wheel. A hole (or holes) is bored in the felloe towards the centre of the wheel,
and the ends of the wire are drawn tight through it (or then) and secured by a
nut (or nuts) just inside the' felloe.
If the wire is tolerably soft and the nut hardened, it can cut its own thread
in screwing on. A suitable lock-washer or nut might be put on as a safeguard.
Should the wire expand or stretch the slack can be taken up with a turn of the
nut.

page_text: There being no wire joint in the body of the tyre the wire is not liable to
breakage by compression when the wheel comes in contact with an obstacle.
Instead of so securing the wire, one end may be turned at right angles and hooked
through the tyre, and the other end screwed for the nut; or the wire (or wires)
may be taken past one another and the ends put through the felloe, which may 5
have one or two lugs brazed on to form a flat bed for the nuts; or the wire (or
wires) may be otherwise secured.
