PROVISIONAL SPECIFICATION.
Improvements in and relating to Wheel Rims for Pneumatic Tyres.
I, JOHN TOWNSEND TRENCH of Kenmare, County Kerry, Ireland, Land Agent,
do hereby declare the nature of this invention to be as follows:--
This invention relates to an improved method of altering the shape or configura-
tion of the concave grooves of wheel rims adapted to carry pneumatic tyres, to
enable the said rims to be used for tyres of other shapes or sections than these for
which they were originally made.
According to this invention the shape of the concave groove of the wheel rim is
altered by winding or wrapping on to it a length of tape or its equivalent either
in combination with or without a length of cord or its equivalent according to
the desired shape it is intended to give the groove of the wheel rim when altered.
In winding the tape or its equivalent on to the wheel rim it is fixed at intervals
by means of marine glue or other waterproof cement, and by winding or wrapping
the tape so that its one edge overlaps the layer below it, the groove of the wheel
rim can be altered to almost any desired shape in cross section.
Instead of using a strip of cord or its equivalent strips or pieces of cork or the
like or other flexible substance may be used.

I, JOHN TOWNSEND TRENCH of Kenmare, County Kerry, Ireland, Land Agent,
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 method of altering the shape or configura-
tion of the concave grooves of wheels rims adapted to carry pneumatic tyres, to
enable the said rims to be used for tyres of other shapes or sections than those for
which they were originally made.
In the accompanying drawing:-
Figures 1, 2 and 3 are views in transverse section showing some methods of
carrying this invention into practice, and Figure 4 is a broken view in plan of
the band shown in Figure 3.
Throughout the views similar parts are marked with like letters of reference

page_text: According to this invention the shape of the concave groove of the wheel rim X
is altered by fitting in it a filling up piece A. This filling up piece may be made
by winding or wrapping on to the rim a length of tape or its equivalent either in
combination with or without a length of cord or its equivalent, according to the
desired shape it is intended to give the groove of the wheel rim when altered, as
shown by Figure 1.
In winding the tape or its equivalent on to the wheel rim it is fixed at intervals
by means of marine glue or other waterproof cement and by winding or wrapping
the tape so that its one edge overlaps the layer below it the groove of the wheel
rim can be altered to almost any desired shape in cross section.
As a modification the filling up piece may consist of one or more shaped blocks A
mounted on a band A¹ the band being arranged either above the blocks A as
shown by Figure 2 or below them as shown by Figure 3. In this construction
the band A preferably consists of a strip of canvas or other fabric, and the
blocks A¹ are preferably made of cork or other light material.
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:-
(1) The improvements in and relating to wheel rims for carrying pneumatic
tyres, as herein specified.
(2) The combination with a wheel rim for carrying pneumatic tyres, of a filling
up piece constructed arranged and adapted to operate as and for the purpose
herein specified.
(3) The combination with a wheel rim for carrying pneumatic tyres, of a filling
up pieces consisting of one or more blocks such as A mounted on a band such as A¹,
herein specified.
