Improvements in or relating to Pneumatic Tyres.
We, JAMES JELLEY and HENRY JELLEY, both of Hill Cross, Coventry, in the
County of Warwick, Tyre Manufacturers, do hereby declare the n. are of this
invention to be as follows:
-
This invention relates to pneumatic tyres, especially those suitable for self-
propelled and other heavy vehicles, whereby the tyre while very strong and hold-
ing securely to the wheel rim is nevertheless easy to detachi.
In carrying out the invenfion we provide each edge of the tyre or cover with
two flaps adapted to intercalate with each other when in position on the tyre,
so that the tyre at the bottom of the rim will present four thicknesses. Each
flap is stiffened by means of a zig-zag wire, two or more of which may be bent
to an arch-shape. Conveniently the wires in the two inner flaps are arched and
the others left flat. Some or all of these flaps may be hooked together by pro-
viding the opposing flaps respectively with hooks and eyes or equivalent fasten-
ings. The tyre may be further secured to the rim by bolts and nuts or equi-
valents.

Improvements in or relating to Pneumatic Tyres.
We, JAMES JELLEY, and HENRY JELLEY, both of Hill Cross, Coventry, in the
County of Warwick, Tyre Manufacturers, 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, especially those suitable for self-
propelled and other heavy vehicles, whereby the tyre while very strong and hold-
ing securely to the wheel rim is nevertheless easy to detachi.
In carrying out the invention we provide each edge of the tyre or cover with
two flaps adapted to intercalate with each other when in position on the tyre,
so that the tyre at the bottom of the rim will present four thicknesses. Each
flap is stiffened by means of a zig-zag wire, two or more of which may be bent
to an arch-shape. Conveniently the wires in the two inner flaps are arched and

viding the opposing flaps respectively with hooks and eyes or equivalent
fastenings.
In the accompanying drawings
Figure 1 is a perspective view of a section of an outer cover of a pneumatic
tyre constructed according to this invention, the edges of the tyre being locked
together as when upon the wheel rim;
Figure 2 is a similar view showing the particular construction of the edges of
the outer cover, and
Figure 3 is also a similar view of Figure 1, the construction of the tyre being
slightly modified.
Like letters indicate like parts throughout the drawings.
Each edge of the outer cover A of the tyre is provided with two flaps B B³,
respectively. These flaps are conveniently made of canvas, stiffened with a zig-
zag wire C.
When the tyre is in position upon the wheel rim the flaps B of one edge are
intercalated with the flaps B¹ of the other edge so that the tyre at the bottom of
the rim presents four thicknesses. The edges being intercalated in the manner
described are prevented from separation by friction, the inflated inner tube.
pressing the upper flap down upon the others so that all are held securely in
place.
The flaps may be made flat so that they lie evenly one upon the other as shown
in Figure 3, or if preferred the wires of the two inner flaps, that is the lower
flap B and the upper flap 131, may be arched as shown in Figure 1. The two ends
of the cover may be further secured if desired by any convenient hook and eye
or equivalent device arranged upon any two of the opposing flaps B B. The
tyre may also be still further secured to the rim by bolts and nuts or their
equivalents.
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 the combination with an outer cover of double inter-
calating edges B B¹ each strengthened with a zig-zag wire C substantially as
described.
2. In a pneumatic tyre the combination with an outer cover of double inter-
calating edges B B¹ the top and bottom flap of the locked edges being flat and
the intermediate flaps convexed substantially as described.
3. The complete tyre substantially as described and illustrated in Figures 1
and 2 or Figure 3 of the accompanying drawings.
Dated this 15th day of June 1900.
