PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, WILLIAM HEALE of 193, Battersea Park Road, Battersea, in the County
of Surrey, Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved device for attaching the edges of the
covers of pneumatic tyres to wheel rims whereby they can be more readily mounted
and dismounted.
According to the present invention a band of stout canvas or other suitable
material is laid in the bottom of the groove of the wheel rim, the width of the said
band being such that its edges coincide approximately with the edges of the wheel
rim. To enable the band to be placed in position its free ends are adapted to be
drawn together by laces or other equivalent devices. Near each end of this band-
on the underside thereof-is fixed a hook. In each edge of the cover is formed a
pocket in the usual manner which contains a wire band the ends of which cross or
overlap and pass out through a common hole in the pocket. On each end of each
of the said wire bands is formed a loop or hook, those on the wire in the pocket in
one edge of the cover being adapted to engage with the hooks mounted on the
band in the wheel rim. The loops or hooks on the wire band in the pocket in the
other edge of the cover are fastened to the wheel rim by being passed over small
headed studs fixed on the inner face of the groove in the wheel rim, under the band
therein, which thereby covers the heads of the studs and prevents them from
injuring the air tube by abrasion. If desired both edges of the cover may be
attached to the wheel rim by a like device.

Improvements in and relating to Pneumatic Tyres.
I, WILLIAM HEALE of 193, Battersea Park Road, Battersea, in the County
of Surrey, Chemist, 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 an improved device for attaching the edges of the
covers of pneumatic tyres to wheel rims whereby they can be more readily mounted
and dismounted.
In the accompanying drawing:
Figure 1 is a broken view in side elevation-partly in section-sbowing the
method of attaching one side of the cover to the wheel rim.

page_text: Figure 2 is a similar view showing the method of attaching the other side of the
cover to the wheel rim, and
Figure 3 is a view in transverse section.
Throughout the views similar parts are marked with like letters of reference.
According to the present invention a band A of stout canvas or other suitable
material is laid in the bottom of the groove of the wheel rim B the width of the
said band being such that its edges coincide approximately with the edges of the
wheel rim. To enable the band to be placed in position its free ends are adapted
to be drawn together by laces or other equivalent devices. At suitable positions
on the underside of the band-near one edge and preferably at the ends thereof-
are fixed hooks a a. In each edge of the cover C is a pocket in which is a wire or
cord D the ends of which cross or overlap and pass out through a hole or holes in
the pocket. On each end of each of the said wires or cords D is formed or fixed a
loop or hook d, those on the wire or cord at one edge of the cover being adapted
to engage with the hooks.a a mounted on the band A in the wheel rim, as shown
by Figure 1, and those on the wire or cord at the other edge of the cover being
adapted to engage with small headed studs bb fixed on the inner face of the groove
in the wheel rim-under the band A-as shown by Figure 2.
It will be seen that the attachments of the wires or cords D are in both cases
covered by the band A which prevents injury to the air tube by abrasion.
As an alternative the wires or cords in both edges may be attached to the
band A.
The air tube is of the usual construction and is provided with any suitable valve
for inflation and deflation.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
(1) The improvements in and relating to pneumatic tyres, substantially as
hereinbefore described and illustrated by the accompanying drawing.
(2) In a pneumatic tyre, the combination with a wheel rim of a band such as A
located therein and carrying hooks such as a, of a cover such as C, of wires or
cords such as D located in pockets in the edges of the cover C and having eyes
such as d adapted to engage with the hooks a, and of an air tube for inflating the
tyre, as and for the purpose set forth.
(3) In a pneumatic tyre, the combination of a rim B having studs or their
equivalents 66 on one side thereof, of a band such as A located in the wheel rim
and having hooks such as a on one side thereof, of a cover such as C having
pockets in its edges which contain wires or cords such as D the ends of which
carry eyes d or their equivalents to engage with the hooks a and studs 6 respectively,
and of an air tube for inflating the tyre, as and for the purpose set forth.
