PROVISIONAL SPECIFICATION.
Improvements in Wheels for Velocipedes and other Vehicles.
I, JOHN TOWNSEND TRENCH of Kenmare Co. Kerry, Ireland, Land Agent,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved attachment to various rims for velocipedes
and other vehicles whereby one class or type of rim may be easily and economically
converted into another class or type of rim, so as to allow of a different kind or
type of pneumatic tyre being used without having to also use a new rim.
According to this invention I mount and fix either adjustably or otherwise an
auxiliary rim or ring on each side of the existing rim, the said strip being of such
a cross section as to make the altered rim coincide as nearly as possible with the
shape of the rim usually used in connection with its particular tyre, for instance if
it is required to convert what is known as the "1896 Dunlop " rim or the "West-
wood" rim for "Dunlop-Welch " tyres into one known as the "Clincher" rim,
I fix in any suitable manner two auxiliary rims or rings, one on each of the edges
of the said "Dunlop" rim, of such a shape and in such a manner as to slightly
increase the diameter of the rim and to make such projecting edges inclined
towards each other so as to practically give the same cross section as that of the
Clincher" rim.

I, JOHN TOWNSEND TRENCH of Kenmare Co. 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 the wheels of velocipedes and other vehicles, and it
consists of an attachment in the form of a pair of rings or hoops adapted to be
fixed to the edges of the rim of the wheel, the object being to easily and
economically alter the shape in cross section of any wheel rim to enable it to carry
a tyre of a different type to that it was originally intended to carry.
In the accompanying drawing which shows-by way of example only-one
method of carrying this invention into practice :-
Figure 1 is a view in transverse section of a "Westwood" rim for carrying a
"Dunlop-Welch " pneumatic tyre.
Figure 2 is a similar view showing the same rim converted for carrying a
pneumatic tyre of the "Clincher" type.

page_text: Figure 3 is a view in transverse section of one of the auxiliary rings or hoops.
Figure 4 is a view in transverse section of an ordinary rim for carrying a
"Dunlop-Welch " pneumatic tyre.
Figure 5 is a similar view of the same rim converted for carrying a tyre of the
"Clincher" type, and
Figure 6 is a view in transverse section of one of the auxiliary rings or hoops.
Throughout the views similar parts are marked with like letters of reference.
On to each edge aa of the rim A to be converted is fixed a ring or hoop B.
These rings or hoops are of such a shape in cross section and are so mounted on
the wheel rim as to alter the shape of the said rim in cross section to enable it to
carry any other type of tyre than that which it was originally intended to carry.
The rings or hoops B may be fixed to the rim A in any suitable or convenient
manner, for instance by being shrunk on, or by brazing, pinning, rivetting or like
.methods.
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.) The improvements in wheels for velocipedes and other vehicles, substantially
as hereinbefore set forth.
(2.) In combination with a wheel rim adapted to carry any particular type of
tyre, of rings or hoops such as B adapted when fixed to the edges of the wheel
rim to so alter its shape in cross section as to enable it to carry any other type of
tyre, as set forth.
