GEORGE GEOFFREY ASTLEY Park House, Willesden Lane, Brondesbury N.W.
Middlesex, Diamond Merchant I do hereby declare the nature of this invention to
be as follows:-
Cork Tyre, with India-rubber, or steel covering or without, in sections or other-
wise. The object of a Cork Tyre is to prevent puncturing, also it will be very
light elastic & durable, & when the outer covering is worn it may be recovered
while the Cork is still intact.

Improvement in Elastic Tyres.
I, GEORGE GEOFFREY ASTLEY, of Park House, Willesden Lane, Brondesbury, in
the county of Middlesex, Diamond Merchant, 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 tyres for cycle and other wheels and has for its object
to construct a tyre which whilst possessing to a large extent the advantages of the
pneumatic tyre, as regards elasticity, obviates the disadvantage of such tyres owing
to its noncollapsability in the case of puncture.
A tyre constructed according to my invention is composed of cork enclosed in
a covering preferably of india-rubber. In practice I prefer that the covering
should be in the form of an india-rubber tube into which lengths of cork of good
quality and cut to fit the said tube are inserted.
My invention will be readily understood by reference to the accompanying
drawing, in which:-
Figure 1 is a transverse section of a wheel tyre constructed according to my
invention and applied to a wheel rim; and,
Figure 2 is a longitudinal section of the same.
a is the tubular cover of my tyre which is preferably made of greater thickness
upon that side which is to form the tread of the tyre, as shewn in the drawing,
and b is the cork filling, the, said filling being in a series of lengths or pieces the
ends of which abut against one another as shewn at c in Figure 2.
In making the tyre the lengths or sections of cork are inserted into a piece of
tube of the required length and then the ends of the said tube are brought together,
to form a tyre of the required internal diameter, and cemented; or, if desired, the
[Price 8d1

page_text: pieces of cork may have the india-rubber moulded around them before vulcaniza-
tion. The diameter of the tyre is slightly less than that of the rim to which
the tyre is to be applied so that the latter has to be stretched somewhat in order
to place it upon the rim (which is indicated at d in the drawing) the sections of
cork separating slightly to permit of the stretching.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:-
1. An elastic tyre composed of lengths of cork enclosed in a covering of
india-rubber or other suitable material, substantially as described.
2. The manufacture and use of elastic tyres, substantially as hereinbefore
described and illustrated in the accompanying drawing.
