page_text: Improvements in or relating to Pneumatic Tyres.
We, JAMES JELLEY and HENRY JELLEY, Managers, both of Parkside, Coventry,
in the County of Warwick, do hereby declare the nature of this invention
to be as follows:-
This invention relates to pneumatic tyres and is applicable to various kinds
and sizes of wheels; it may be carried out in the following manner.
The tyre may be placed upon any suitable form of channelled rim in which
it is intended to lie. The tyre may be used either as a tubeless-that is without
an inner air tube-or as an ordinary compound tyre consisting of an air tube
and cover; we will now describe it as provided with an air tube.
An air tube being employed the invention will be applicable to the cover
which may be made of canvas, fabric or other suitable material as usual, the
invention relating to the edges and the manner of joining them and securing
them in the rim. Each edge is split or double so as to form two flaps, one of
which, say the inner, is strengthened or stiffened in any suitable manner but
preferably by means of a zigzag wire. This stiffening may be arched, partly to
stiffen it and partly so that the edges thus curved when they lie one on top of the
other are less liable to draw apart.
The outer edges overlap and are connected together at suitable intervals by
the well-known stud glove fasteners, or other suitable means of securing these
Haps together may be employed.
If the stiffening wires or equivalent are placed in the outer flaps or edges
the fastenings may be placed in the inner one or the one pair of edges may
be dispensed with and the fasteners placed in the remaining pair which would
be the stiffened ones.

Improvements in or relating to Pneumatic Tyres.
We, JAMES JELLEY and HENRY JELLEY, Managers, both of Parkside, Coventry.
in the County of Warwick, 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:-

page_text: This invention relates to pneumatic tyres and is applicable to various kinds
and sizes of wheels; it may be carried out in the following manner.
The tyre may be placed upon any suitable form of channelled rim in which
it is intended to lie. The tyre may be used either as a tubeless-that is without
an inner air tube-or as an ordinary compound tyre consisting of an air tube
and cover; we will now describe it as provided with an air tube.
An air tube being employed the invention will be applicable to the cover
which may be made of canvas, fabric or other suitable material as usual, the
invention relating to the edges and the manner of joining them and securing
them in the rim. Each edge is double flapped i.e. split or double so as to form
two flaps, one of which, say the inner, is strengthened or stiffened in any suitable
manner but preferably by means of a zigzag wire. This stiffening may be
archeil, partly to stiffen it and partly so that the edges thus curved when they
lie one on top of the other are less liable to draw apart.
The outer edges overlap and are connected together at suitable intervals by
the well-known stud glove fasteners, or other suitable means of securing these
flaps together may be employed.
If the stiffening wires or equivalent are placed in the outer flaps or edges the
fastenings may be placed in the inner one.
The accompanying drawing is a perspective elevation of part of a compound
tyre constructed according to this invention, one end being in section and the
other opened out showing the arrangement of the various parts.
The edges of the outer cover A are double flapped, that is to say each is
provided with flaps A¹ A which are preferably formed by the division of a
duplex canvas lining which may conveniently consist of two portions solutioned
or otherwise fixed together. The inner flaps A are strengthened or stiffened
by the insertion of a zigzag wire B within a fold of the canvas forming the flap.
The wire may be transversely arched as shown in order to further stiffen the
flaps and to lessen any tendency they may have to draw apart when one lies on
the top of the other. The flaps A2 are provided with a fastening device such as
hooks C and eyes D situated respectively on the inner and outer member of the
outer pair of flaps A and adapted to engage each other.
As an alternative, the inner flaps A' may be fastened together while the outer
pair of flaps A² carry the zigzag wire. In both cases the two pairs of flaps lie
within the channel of the rim to which the tyre is applied and do not embrace
the edges of the rim. The tube may be readily removed when deflated by
undoing the fastenings connecting one pair of flaps.
The constructions above referred to may be used as tubeless tyres by omitting
the air-tube and lining the case with a thin layer of rubber extending to and
covering the inner pair of flaps, which in this case always contain the stiffening
wires. The air-seal is formed by the insertion of a strip of soft rubber between
the inner pair of flaps.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In a pneumatic tyre an outer cover with double flapped edges one flap on
each edge containing zigzag wire the other having a fastening device substantially
as described.
2. In a pneumatic tyre an outer cover with double flapped edges one flap on
each edge containing zigzag wire transversely arched the other having a fastening
device substantially as described.
3. A tubeless pneumatic tyre with double flapped edges one flap on each edge
containing zigzag wire the other having a fastening device substantially as
described.
4. A tubeless pneumatic tyre with double flapped edges one flap on each edge

page_text: containing zigzag wire transversely arched the other having a fastening device
substantially as described.
5. The complete tyre substantially as described and illustrated in the
accompanying drawing.
