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 consists of improvements relating to pneumatic tyres for cycle and
other vehicle wheels my object being to provide ready and convenient means for
effectually securing such a tyre to the wheel rim quite independently of the pressure
due to inflation.
For securing a tyre in accordance with my invention I employ a wheel rim having
a trough or channel on each side with an outward projection from the inner wall of
each channel for the purpose of forming an abutment for the lug or projection or
I also form or attach at
projections which I provide at the edges of the tyre cover.
each side of the cover a free ended or flap like strip, such strips being so arranged
that they can be pressed into the channels after the herein before described lugs have
been placed in position in the channels or grooves and under the projections from the
said inner walls of the same. Such flap like pieces thus act as wedges and effectually
prevent outward movement of the edges of the cover and so secure the complete
tyre to the wheel rim. No displacement of the wedge pieces can occur by the
pressure on the tread of the tyre during riding or when in service, but they can be
readily withdrawn by the fingers from the wheel rim for permitting of reinoval of the
tyre for repairs or otherwise.
The rim is preferably provided with a central or bridge like piece which effectually
prevents inward lateral movement of the edges of the tyre cover.
To assist in the ready removal of the flap like wedge pieces I sometimes form
a thumb aperture in a convenient position or positions along. the edges.
I do not limit myself to any one form or section of the wheel rim but adapt any
suitable section, in all cases providing grooves or channels such as herein before
described.

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

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention consists of improvements relating to pneumatic tyres for cycle and
other vehicle wheels my object being to provide ready and convenient means for
effectually securing such a tyre to the wheel rim quite independently of the pressure
due to inflation.
For securing a tyre in accordance with my invention I employ a wheel rim
having a trough or channel on each side with an outward projection from the inner
wall of each channel for the purpose of forming an abutment for the lug or projection
or projections which I provide at the edges of the tyre cover. I also form or
attach at each side of the cover a free ended or ap like strip, such strips being so
arranged that they can be pressed into the channels after the herein before described
lugs have been placed in position in the channels or grooves and under the
projections from the said inner walls of the same. Such flap like pieces thus act as
wedges and effectually prevent outward movement of the edges of the cover and so
secure the complete tyre to the wheel rim. No displacement of the wedge pieces
can occur by the pressure on the tread of the tyre during riding or when in service,
but they can be readily withdrawn by the fingers from the wheel rim for permitting
of removal of the tyre for repairs or otherwise.
The rim is preferably provided with a central or bridge like piece which effectually
prevents inward lateral movement of the edges of the tyre cover.
To assist in the ready removal of the flap like wedge pieces I sometimes form
a thumb aperture in a convenient position or positions along the edges.
I do not limit myself to any one form or section of the wheel rim but adapt any
suitable section, in all cases providing grooves or channels such as herein before
described.
The accompanying illustration represents a section of a pneumatic tyre constructed
in accordance with my invention. The rim in this case is made up of inner and
outer parts A and B respectively, and has side troughs as shown for the reception
of the lugs or projections C¹ of the cover C, and the free end or flap like
strips D.
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
I claim is.
In pneumatic tyres for cycle and other vehicle wheels the combination comprising
a cover as C, having lugs or projections as C¹, and free ended or flap like strips D,
with a rim having a trough on each side for the reception of the said parts C¹ and D,
substantially as and for the purposes described and as illustrated.
