I HENRY SANSOM, of 22, Park Road, Liverpool, Gentleman, do hereby declare
the nature of this invention to be as follows:-

My invention relates to improvements in the tyres of carriage and other wheels
and consists in fitting over the ordinary felloes or rim of carriage wheels a U shaped
steel or open casing wherein is secured an inner india rubber tyre projecting beyond
the latter. A steel hoop of lenticular cross section and somewhat larger in
diameter than the inner india rubber tyre aforesaid is placed in a heated state
around the same and in order to prevent the heat from this hoop from melting the

hoop or, outer tyre cools it contracts and gradually fits tightly over the india rubber
tyre.
According to a modification of my invention more particularly applicable for
heavy vehicles such as carts, cars omnibusses and the like, the inner rubber tyre
is made to recede within the open steel casing or U shaped tyre so that the outer
hoop or tyre may enter the same after it has cooled, thus forming a stronger
arrangement.

Improvements in the Tyres of Carriage and other Wheels.
1, HENRY SANSOM, of 22 Park Road, Liverpool, 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 :-
My invention relates to improvements in the tyres of carriage and other wheels
and consists in fitting over the ordinary felloes or rim of carriage wheels a U shaped
steel or open casing wherein is secured an inner india rubber tyre projecting beyond
the latter. A steel hoop of lenticular cross section and somewhat larger in
diameter than the inner india rubber tyre aforesaid is placed in a heated state
around the same and in order to prevent the heat from this hoop from melting the
india rubber tyre, a layer of asbestos is interposed between the two and as the steel
hoop or outer tyre cools it contracts and gradually fits tightly over the india rubber
tyre.
According to a modification of my invention more particularly applicable for
heavy vehicles such as carts, cars omnibuses and the like, the inner rubber tyre is
made to recede within the open steel casing or U shaped tyre so that the outer
hoop or tyre may enter the same after it has cooled, thus forming a stronger
arrangement.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon."
Fig. 1 is a transverse section of a tyre with an iron hoop and asbestos.
Fig. 2 is a transverse section of a tyre with an iron hoop and asbestos of an

otherwise, in, or on, the india rubber I place a layer of asbestos e to prevent the
melting of the india rubber tyre a when the steel hoop d is placed thereon. A steel
hoop d oval or half round in section is placed on the asbestos e in a heated state,
the said hoop d as it cools contracts and fixes itself in its position as illustrated in
Figs. 1 and 2.
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. In a tyre for carriage wheels, the combination of an india rubber tyre a and a
layer of asbestos e with a steel-hoop-d fitted into a rim c, substantially as herein
described and according to Figs. 1, and 2, of the accompanying drawing.
.
2. In a tyre for carriage wheels, the combination of an india rubber tyre a and a
layer of asbestos e placed in, or on, the said india rubber tyre, substantially as
herein described and according to the accompanying drawing.
Dated this 7th day of November 1893.
