PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatic Tyres.
We, HENRY JELLEY of 1 Rothesay Terrace, Coventry in the County of
Warwick, Manager, and JAMES JELLEY of 122 St. John's Hill, Wandsworth,
in the County of Surrey, Manager, do her-'y declare the nature of this invention
to be as follows:-
This invention relates to pneumatic tyres, the tyre being complete in itself and
not requiring a special rim.
In carrying out the invention we use an air tube as usual, and place that in a
cover formed of any suitable material say for example canvas covered with india-
rubber. The edges of the cover may be joined by a suitable fastening preferably
a spring fastening, say the well known Dent's glove fasteners, the fastener being
secured upon one edge of the cover, and passing through a hole, eyelet or equivalent
in the other, and thus connecting the two.
In the sides of the cover we place flexible bands conveniently of metal, say
aluminium or steel, which serve to prevent the tyre from puckering between the
fasteners as it would be liable to do without the bands. Instead of complete bands
sections may be employed of convenient length, either form being preferably
carried in pockets provided for the purpose, though they may be merely secured
upon the face, preferably the inner face, of the tyre if preferred. If these bands
are so placed that they project partly outside the rim they serve to protect the air
tube from damage by the rim, a point of some importance when the tyre is used
for heavy vehicle wheels.
The tyre may be specially secured in the rim if desired as by cement or
mechanical fastenings, but we find that it will secure a hold in the rim by simple
inflation.

Improvements in or relating to Pneumatic Tyres.
We, HENRY JELLEY of 1 Rothesay Terrace, Coventry, in the County of
Warwick, Manager, and JAMES JELLEY of 122 St. John's Hill, Wandsworth, in
the County of Surrey, Manager, 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 aud by the following statement :-
This invention relates to pneumatic tyres, the tyre being complete in itself and
not requiring a special rim.
In carrying out the invention we use an air tube as usual, and place that in a
cover formed of any suitable material say for example, canvas covered with india-
rubber. The edges of the cover may he joined by a suitable fastening preferably
a spring fastening, say the well known Dent's glove fasteners, the fasteners being

in the other, and thus connecting the two.
In the sides of the cover we place flexible bands, conveniently of metal, say
aluminium or steel, which serve to prevent the tyre from puckering between the
fasteners as it would be liable to do without the bands. Instead of complete bands,
sections may be employed of convenient length, either form being preferably
carried in pockets provided for the purpose, though they may be merely secured
upon the face, preferably the inner face, of the tyre if preferred. If these bands
are so placed that they project partly outside the rim they serve to protect the air
tube from damage by the rim, a point of some importance when the tyre is used
for heavy vehicle wheels.
The tyre may be specially secured in the rim if desired as by cement or
mechanical fastenings, but we find that it will secure a hold in the rim by simple
inflation.
In the accompanying drawings:-
Figure 1 is a perspective view of a portion of a tyre constructed according to
this invention, one end being shown in cross section;
Figure 2 shows to a larger scale than that of Figure 1 portions of the tyre
illustrated in the latter, and indicates more clearly the details of the fastening;
Figure 3 is a view similar to Figure 2 showing an alternative construction of
fastening.
Like letters indicate like parts throughout the drawings.
With reference first to Figures 1 and 2, A is the inner air tube, and B is the outer
cover, of canvas and rubber. In the edges of the cover are placed plates C, D,
preferably of metal, say aluminium or steel, and arranged so that their ends
approximately meet as at C8 D*; thus the plates form two continuous series
extending completely around the tyre. These plates are carried in pockets B' as
shown. In both sides of the cover the pockets B' are cut away at intervals as
shown, and through the openings thus provided portions of the plates project. In
the plate C holes C' are formed at suitable intervals corresponding with the openings
in the pockets; in the plate D fastening devices are fixed so as to be capable of
engaging with the holes C'. Each plate D is provided with a lateral projection D',
each projection having lugs D2 which are turned up at right angles thereto, at
each side of it as shown; small holes D3 are drilled in these lugs and in these
holes a lever E is pivotted by means of two projections E' which extend from the
lever and enter the holes D³. The lever has unequal arms, the shorter arm being
adapted to bear upon a spring D' struck up from the projection D' in such a manner
that when the long end of the lever E is passed through the hole C¹ and turned
over again it draws it towards the plate D, and the spring D retains the longer
arm of the lever against that plate and thus securely holds together the two edges
of the cover. F is a strip of canvas secured to one edge of the tyre cover and
extended over the portion of the air tube which is nearest to the plates C and D,
in order to protect the air tube from any possibility of being chafed by the fastening
devices.
Instead of the plates C, D, continuous bands C', D', may be provided as indicated
in Figure 3.
Instead of making the fastening devices in part of portions of the bands
or plates they may be constructed separately and afterwards affixel thereto.
Instead of metal bands or plates in the edges of the tyre the fastenings may be
applied to the edges of a cover otherwise stiffened.
In the alternative construction of fastening shown in Figure 3 one band C is
provided with holes C' and the other band D7 has fixed upon it short studs D each
split down the middle as at D and having its outer end enlarged. The enlarged
outer end of each stud D is of such diameter that it will just pass through the
hole C' when the two bands or plates are brought together; when the outer end
has passed through the hole the sides of the stud spring apart into their normal
position, thus securely engaging the bands or plates C' and D' together.

page_text: To prevent any possibility of the head of the stud D' being accidentally
forced back through the hole C¹, the latter may be provided with a cover
such as C.
Instead of the fastenings herein before described by way of example any other
desired form of fastening may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Securing together the edges of the outer cover of a pneumatic tyre with
spring fastenings substantially as described.
2. The combination in the edges of the outer cover of a pneumatic tyre of bands
or plates such as CD with spring fastenings substantially as described.
3. As a fastening for the cover of a pneumatic tyre a spring fastener such
as described having an extended plate such as C or D forming one of a series
which extend entirely around the edge of the cover substantially as described.
4. In a pneumatic tyre the combination with a hoop or band such as C or D'
which extends around the edge of the cover of spring fasteners substantially as and
for the purpose described.
5. The fastening for the cover of a pneumatic tyre substantially as described and
illustrated in Figures 1 and 2 of the accompanying drawings.
6. The fastening for the cover of a pneumatic tyre substantially as described and
illustrated in Figure 3 of the accompanying drawings.
