OMPLETE SPECIFICATION.
Improvements in or relating to the Rims and Tyres for Cycle and
other Wheels.
I, HUGH FAULKNER of Rockleigh, London Road, Leicester, Manufacturer, 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 has reference to the rims and tyres for cycle and other wheels,
and consists essentially in an improved construction of rim and tyre so that the
latter can be readily secured in position on the former and removed therefrom when
desired.
The invention also admits of the tyre being fixed in position on the rim without
the use of cement or other adhesive material.
_For this purpose the tyre is constructed with flaps or wings which may be
adapted to overlap each other, and are perforated to pass over short vertical studs
fixed on the rim and provided, optionally, at their upper ends with an eye or opening,
through which a cord, rod, or equivalent may be passed in the direction of the
length of the tyre or circumference of the wheel, in order to maintain the tyre in
position.
The invention will be best understood from the following description in reference
to the accompanying drawing in which
Figure 1 is a cross section of a pneumatic tyre constructed in accordance with this
invention.
Figure 2 is a similar view of a pneumatic tyre and wheel rim, showing the former
secured in position on the latter as hereinbefore referred to.
Figure 3 is a plan view of the inner or underside of a portion of the rim of a
wheel provided with my improved tyre.
The tyre is composed of rubber A indicated by the diagonal or sectional lines,
and layers of canvas B, represented by the dotted lines (Figures 1 and 2) moulded
and vulcanized together in the usual well known manner.
The tyre is also formed on the inner or underside with flaps or wings A' of such
proportions as to be capable of overlapping each other as shown.
Each of the said flaps or wings is provided with a series of perforations running
in the direction of the length thereof, through each of which an eyelet and washer C
or equivalent is clenched or otherwise fitted to increase the durability of such
perforations.
The perforations in the wings or flaps are passed over a series of pins or studs D
or equivalents fixed in the rim E of the wheel.
The number of such pins or studs, is equivalent to the number of perforations
in one flap or wing and the construction of the latter in relation to the studs is such
that when the tyre is fixed in position on the wheel and the usual air tube A'
filled with compressed air or gas is inserted in the air space A' in the well
known manner, the flaps are slightly in tension and bind somewhat against
the sides of the studs and are thereby not very liable to become accidently
detached.
But, as an additional safeguard to maintain the tyre in its proper position when
once fixed on the rim in the manner shewn in Figures 2 and 3, the studs are each
perforated so as to form an eye in the upper end thereof and through each of such
eyes a flexible metallic cord F or equivalent is passed in the direction of the
circumference of the wheel and is tightly knotted or otherwise suitably secured for
he purpose named.
In order to reduce the friction between the heads of the studs and the tyre

page_text: a removable layer or strip of vulcanized rubber and canvas G or other suitable
material is inserted between the rim E and the underside of the tyre as shewn in
Figure 2.
The flaps A¹ have alternately long and short slits A' A' in the direction of their
width so as to pass between the spokes H, the long and short slits in the upper flaps
being placed over the short and long slits in the under flaps as indicated by the
dotted lines in Figure 3.
Although the invention has been herein before described in reference to pneumatic
tyres it will be readily understood that it is equally applicable to cushion tyres or
even if need be to solid tyres.
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. An elastic tyre with wings or flaps perforated and eyeletted and adapted
to overlap and engage a series of pins or studs on the wheel rim substantially as
and for the purpose described and illustrated in the accompanying drawing.
2. An elastic tyre provided with wings or flaps perforated and eyeletted and
adapted to overlap and engage a series of pins or studs on the wheel rim, the said
pins or studs being provided with eyes through which a metallic cord or equivalent
is passed to maintain the tyre in position substantially as described and illustrated
in the accompanying drawing.
3. A wheel rim provided with a series of pins or studs to engage perforations in
the wings or flaps of an elastic tyre, and a metallic cord or equivalent passing through
the eyes in the said pins or studs to maintain the tyre in position substantially as
described and illustrated in the accompanying drawing.
