PROVISIONAL SPECIFICATION.
Improvements relating to Pneumatic Tyres for Cycle and other
Vehicle Wheels."
I, ARTHUR EDWARD BECK, of 19, Fernley Road, Sparkhill, near the City of
Birmingham. Manufacturer. do hereby declare the nature of this invention to be
as follows: -
This invention relates to the manner in which I secure a pneumatic tyre to a cycle
or other vehicle wheel rim independently of the internal pressure due to inflation.
In carrying my invention into effect I employ a wheel rim of any suitable section
for the particular service for which the wheel is required, but having an aperture at
each side for the reception of the ends of the cover. Such apertures have preferably
a rectangular form and at each side of the cover I insert in the material correspondingly
shaped lock or catch pieces. When the edges of the cover are so fitted with such lock
or catch pieces, disposed in short lengths around the circumference, the edges can be
readily inserted into the angular apertures before inflation of the tyre by bringing
them to the required position, but a tension or stress on the cover in any direction
that can be imposed upon it when inflated and in service will not effect the
displacement of the edges owing to the angular formation of the rim apertures and
the like formation of the tyre or cover edges with the embedded metallic or other lock
or catch pieces, and thus the tyre will be effectually secured to the rim.
On the deflation of the tyre it can be readily released from the rim by pulling the
cover edges in the required direction and thus effecting their withdrawal from the
apertures at each side of the rim.
I do not limit myself to a right angle formation of the rim apertures but make them
of such a form and so arrange the edges of the cover that whilst they can be readily
inserted or withdrawn at the will of the rider or user, no detachment will occur when
in service.

I, ARTHUR EDWARD BECK, of 19 Fernley Road, Sparkhill, near the City of Birmingham,
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 relates to the manner in which I secure a pneumatic tyre to a cycle
or other vehicle wheel rin independently of the internal pressure due to inflation.
In carrying my invention into effect I employ a wheel rim of any suitable section
for the particular service for which the wheel is required, but having an aperture at
each side for the reception of the ends of the cover. Such apertures have preferably
a right angle form and at each side of the cover I insert in the material correspond-
ingly shaped lock or catch pieces. When the edges of the cover are so fitted with
such lock or catch pieces, disposed in short lengths around the circumference, the
edges can be readily inserted into the angular apertures before inflation of the tyre
by bringing them to the required position, but a tension or stress on the cover in any
direction that can be imposed upon it when inflated and in service will not effect the
displacement of the edges owing to the angular formation of the rim apertures and
the like formation of the tyre or cover edges with the embedded metallic or other
lock or catch pieces, and thus the tyre will be effectually secured to the rim.
On the deflation of the tyre it can be readily released from the rin by pulling the
cover edges in the required direction and thus effecting their withdrawal from the
apertures at each side of the rim.
The accompanying illustration represents a section of a pneumatic tyre constructed
in accordance with my invention.
The hollow rim A is provided with external side apertures each having the form of
a right angle as illustrated for the reception of the correspondingly shaped metallic
or other rigid lock or catch pieces as B. Such lock or catch pieces are preferably
embedded in whe edges of the cover C as shown, but they can be attached in any
other convenient manner.
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.-
In pneumatic tyres for cycle and other vehicle wheels the combination comprising
a rim as A having external side apertures of a right angle formation with a cover
having correspondingly shaped lock or catch pieces embedded within or attached to
its edges, substantially as and for the purposes described and as illustrated.
