and other Vehicles.
I, JOHN SMITH, of Duke Street, Athy, County Kildare, Ireland, Gentleman,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to improvements in, and in relation to the
rims of wheels for carriages and other vehicles, whereby greater rigidity and
economy are effected than by any method hitherto employed so far as I am
aware.
The invention consists in forming on the outer periphery of the ordinary
wooden felloe a circumferential groove of suitable section according to the
weight and general character of the wheel.
Into this groove is sprung a suitable band of iron or steel round in section.
This the essential feature of my invention simply lies in the adaptation of a
rim, round in section, carried in a suitable groove provided in the periphery of
the ordinary felloe.

I, JOHN SMITH, of Duke Street, Athy, County Kildare, Ireland, Gentleman,
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:-i
This invention has reference to improvements in, and in relation to the rims
of wheels for carriages and other vehicles, whereby great rigidity and economy
are effected.
The invention consists in forming on the outer periphery of the ordinary
wooden felloe a circumferential groove of suitable section according to the weight
and general character of the wheel.
Into this groove is sprung a suitable band of iron or steel round or approxi-
mately round in section.
Thus the essential feature of my invention lies simply in the adaptation of a
[Price 8d.]

page_text: rim, round or approximately round in section, carried in a suitable groove pro-
vided in the periphery of the ordinary felloe.
The accompanying drawings will enable my said invention to be more readily
understood.
Fig. 1 is a side view of portion of a wheel rim constructed according to my
invention.
Fig. 2 is a cross section of same.
A illustrates the ordinary wooden felloe the section of which is preferably
dome shaped as shewn; B is the tyre prepared, to suit the wheel to which it is
to be applied.
The tyre is expanded diametrically by the application of heat' whereupon it
is sprung into the groove, on to the wooden rim, to which it accommodates itself
in the act of cooling, thus taking up a rigid position and binding the wheel
tightly together.
It is obvious that although I speak of a tyre of round section it may be approxi-
mately round, or even oval, should it be found desirable to depart from the truly
round section.
Amongst the advantages of my improved tyre may be mentioned the
following:
(1) It presents a neat and smart appearance.
(2) Being round or approximately round it is much stronger and more rigid
and has a greater power for binding the wheel together.
(3) It requires no riveting or spiking, which often proves fatal to wooden
felloes.
(4) It prevents the periphery of wheels flattening at weak points, which fre-
quently occurs with other tyres when a little worn.
(5) It reduces the draught considerably.
(6) It diminishes concussion as it glides past, instead of running over stones
and other obstacles.
(7) It saves the wooden felloes from stones, and road debris as it elevates them
considerably from contact therewith. It also obviates splashing, keeping the
vehicle always clean.
(8) Being grooved on to the wheels, it cannot readily come off, and is not
likely to loosen.
(9) It will last double the lifetime of ordinary tyres, presenting as it does
a small rolling surface for wear.
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 wheels for carriages and other vehicles the use and application of a tyre
of iron or steel round, or approximately round in section, fitted in a circum-
ferential concave groove provided in the ordinary felloes of the wheel, substan-
tially as herein described and illustrated in the accompanying drawings.
Dated this 22nd day of June 1899.
