Improvements in and relating to Vehicle Wheels.
We, ERNEST GEORGE EDMANDS, of Great Charles Street Birmingham, in the
County of Warwickshire, Manager, and THE GRAPPLER PNEUMATIC TYRE AND
CYCLE Co. LTD.. of 27, Clare Street, Dublin, in the County of Dublin,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in rims for pneumatic tyres, the
object being to provide for the ready application of pneumatic tyres to existing
wheels, and to enable the said tyres to be readily detached in case of damage, so
that the wheels can run on their ordinary iron tyres.
The pneumatic tyre rim is made with a groove or its equivalent on its inner
face so that it can be readily fitted over and clamped to the felloe of the wheel,
the said groove being preferably slightly coned to enable it to more easily adapt
itself to the felloe of the wheel.
The pneumatic tyre rim is formed in one or more parts or sections to enable it
to be placed in position on the wheel and to facilitate stowage when not in use,
the ends of the said parts being preferably adapted to overlap one another. The
part or parts of the rim are fixed together and to the felloe of the wheel either
by radial or transverse bolts, or by means of one or more contractible bands or
wires running circumferentially round the rim. The outer face of the rim is
shaped to receive the particular type of pneumatic tyre it is intended to receive.
In pneumatic tyres the covers of which are fixed to the rims by contractible bands
or wires we utilize the same bands or wires to clamp or fix the rim to the felloe
of the wheel.

In the accompanying drawing which illustrates our invention ;-
Figure 1 is a view in transverse section, and
"
Figure 2 a view in broken longitudinal section showing one form our invention
may assume.
Figures 3, 4, 5 and 6 are views in transverse section showing modifications
thereof.
Throughout the views similar parts are marked with like letters of reference...
Our improved rim for pneumatic tyres is formed with a groove A or its equivalent
on its inner face adapted to fit over the felloe X of an ordinary vehicle wheel and
it may be formed either out of two strips or pieces of metal as shown by Figures 1
and 6 or out of one strip as shown by Figures 3, 4 and 5, the flanges a, a, forming
the sides of the groove being preferably made slightly tapered or coued so that
the rim can more easily adapt itself to the felloe of the wheel. The groove A¹
in the outer part of the rim is shaped according to the type of tyre it is intended
to receive, the sections shown by Figures 1, 3 and 4 of the accompanying drawing
are for the type of tyre known as the "Grappler," and that shown by Figure 6
for the type of tyre known as the Welch-Dunlop.
The rim is formed in one or more parts or sections to enable it to be readily
placed in position over the felloe of the wheel and also to facilitate stowage when
not in use. The ends of the part or parts are preferably adapted to overlap as
shown by Figure 2, but this is not obligatory. The parts or sections of the rin
are fixed together and to the felloe of the wheel either by means of radial bolts B
as shown by Figure 2, or by means of contractible bands or wires C running
circumferentially round the rim on each side thereof as shown by Figures 3 and 4.
When the rim is adapted to receive a pneumatic tyre of the type having con-
tractible hoops or bands in the edges of the cover we may utilize the said
contractible bands or wires to clamp or fix the section or sections of the rim to
the felloe of the wheel as shown by Figure 5.
It will be seen that by the use of this improved rim any type of pneumatic tyre
can easily and readily be applied to the existing wheels of road vehicles without
any alteration and without the aid of skilled labour, and also that the tyres can
be rapidly and readily removed from the wheels in case they become so damaged
as to be unrepairable on the spot, and providing the rim is made in sections of a
convenient length the detached tyre and rim can be easily and conveniently
carried or stowed away.

Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved construction of rim for applying pneumatic tyres to the wheels
of existing road vehicles without alteration, as set forth.
