Improvements in and relating to Pneumatic Tyres.
I, JOHN WAIGHT, of the "Encore" Cycle Works, Kirkwood Road, Peckham,
in the County of Surrey, Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved device for attaching and securing the
covers of pneumatic tyres to wheel rims and to an improved construction of cover
and wheel rim, the objects being, first, to facilitate the attachment and removal of
the cover from the wheel rim, and secondly, to prevent side rolling of the tyre on
the rim.
I attain these ends in the following manner :-
The rim of the wheel, which may be either of the hollow or solid type, bas two
circumferential grooves located one on each side of the rim with an elevated centre
part and outwardly extending side flanges. The cover is made of rubber reinforced
with canvas in the well-known manner and it has enlargements formed on its edges.
The shape of these enlargements is such that when they are folded back to form
pockets to receive the fixing bands or wires, they rest on the side flanges of the
rim and so form supports against which the sides of the cover rest when the tyre is
inflated.
1
One end of each fixing band or wire is formed in the shape of a hook or eye
adapted to engage with a book or stud in the bottom of the groove in the wheel
rim. The other end of the band or wire is threaded to receive any suitable form
of nut. This end of the band or wire passes out of the groove in the wheel rim to
the inner side thereof through a suitably shaped hole, and it is then drawn up
taut to fix the cover to the wheel rim by means of the aforesaid nut screwed on
the threaded end of the said band or wire.
It will be understood that each edge of the cover is fixed to the wheel rim by a
similar band or wire.
COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, JOHN WAIGHT, of the "Encore" Cycle Works, Kirkwood Road, Peckham,
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 and by the following statement :-
This invention relates to an improved device for attaching and securing the
covers of pneumatic tyres to wheel rims and to an improved construction of cover
and wheel rim, the objects being, first, to facilitate the attachment and removal of
the cover from the wheel rim, and secondly, to prevent side rolling of the tyre on
the rim.

page_text: I attain these ends in the manner shown by the accompanying drawing in
which:-
Figure 1 is a broken view in side elevation showing the essential features of my
invention.
Figure 2 is a view in transverse section, and
Figure 3 is a view of one of the fixing bands or wires.
Throughout the views similar parts are marked with like letters of reference.
The rim A of the wheel, which may be either of the hollow or solid type, has
two circumferential grooves a, a, located one on each side of an elevated central
part a¹ and outwardly extending side flanges a², a². The cover B of the tyre is
made of rubber reinforced with canvas in the well-known manner and it has
enlargements b, b, formed on its edges. The shape of the enlargements b, b, is such
that when they are folded back to form pockets 6', ', to receive the fixing bands
or wires C, C, they rest on the side flanges a², a³, of the rim and so form supports
against which the sides of the cover rest when the tyre is inflated.
One end of each fixing band or wire C is adapted to engage with the wheel
rim either by being bent to form a hook e adapted to engage with a hole in
the bottom of one of the grooves a in the wheel rim and to be fixed therein by
means of a nut c¹ screwed on the threaded end of the hook c or by being made in
the shape of a hook or eye adapted to engage with a hook or stud in the bottom of
one of the grooves in the wheel rim. The other end of the band or wire C passes
out of the groove in the wheel rim to the inner side thereof through a hole a³
made through a suitably shaped piece a fixed to the wheel rim, and it is drawn up
taut to fix the cover to the wheel rim by means of a nut screwed on the end of
the band or wire which is threaded to receive it.
It will be understood that each edge of the cover is fixed to the wheel rim by a
similar band or wire and that suitable holes or passages are made through the
cover for the passage of the ends of the fixing bands or wires.
The air tube D is of the usual construction and is fitted with any suitable form
of valve for inflation and deflation.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what claim is:
(1) The improvements in and relating to pneumatic tyres substantially as herein-
before described and illustrated by the accompanying drawing.
(2) The combination of a wheel rim such as A having two circunferential
grooves a, a, a raised central part a' and outwardly extending side flanges a³, a²,
and of a tyre cover such as B, having enlarged edges b, b, adapted when folded
back to form pockets 6, 6, to receive the fixing bands or wires, the said enlarged
edges being shaped to rest on the flanges a², a³, of the wheel rim, as and for the
purpose set forth.
(3) The combination of a wheel rim such as A having two circumferential
grooves a, a, a raised central part a¹ and outwardly extending side flanges a³, a³, of
a tyre cover having enlargements b, b, on its edges adapted to rest on the
flanges a, a, of the wheel rim, and of the fixing bands or wires C adapted to lie in
the pockets b', b', formed by the upturned edges of the cover b, all combined,
arranged and adapted to operate as and for the purpose set forth..
Dated this 11th day of October 1894.
