Improvements in Securing India Rubber Tyres to Wheels.
I JEAN BAPTISTE LABOURDETTE, of 130 Avenue Malakoff, Paris, in the
Republic of France, Coach Builder, do hereby declare the nature of this invention
to be as follows:-
Rubber tyres applied to wheels, and particularly to the wheels of carriages,
afford great advantages, the movement is softer, shocks are deadened and vibration
and noise are suppressed, but hitherto the system of attaching these tyres has been
very defective. The wooden felloes are encircled by a U shaped iron tyre, that is
to say one with raised edges and it is on this iron tyre and between the raised edges
that the rubber tyre is fitted.
Numerous causes such as shocks, tramway rails &c. are apt to stretch the rubber,
the cement joint of which gives way and it then parts from the iron tyre. From
this arise annoyances and even the possibility of certain dangers which have
prevented the more general use of rubber tyres, in spite of the advantages which
they otherwise present.
On the wooden felloe of a wheel constructed according to this invention is fixed
an iron tyre raised at its edges and enlarged at the upper part thus forming a
cushion at each side. It is within this iron tyre that the means of attachment are
fixed. They consist of one or more wires of a round, triangular, flat or other shape
passing through holes bored at intervals in the iron tyre, either in its lower or
lateral part. Inside this tyre the wire is raised so as to leave a free space between
it and the tyre. Outside it passes along a groove suitable to the size and shape of
the wire and this groove is then flattened in, until that side of the tyre is completely
closed, either by means of rivets of T or any other suitable shape placed at intervals
in the iron tyre, or by special strips of rubber. The whole or any one of these
apparatuses is inserted in the rubber prepared for this purpose. In this manner
the rubber tyre is perfectly consolidated. It cannot be displaced to the right or
"the left since on one hand it is held by the raised sides of the iron tyre and on the
other hand it is sustained by the attachments. It cannot be detached since by this
kind of insertion its mass is connected to the iron tyre.

I JEAN BAPTISTE LABOURDETTE, of 130 Avenue Malakoff, Paris, in the
Republic of France, Coach Builder, 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 :-
Rubber tyres applied to wheels and particularly to the wheels of carriages

and noise are suppressed, but hitherto the system of attaching these tyres has been

page_text: very defective. The wooden felloes are encircled by a U shaped iron tyre, that is
to say, one with raised edges, and it is on this iron tyre and between the raised edges
that the rubber tyre is fitted..
Numerous causes such as shocks tramway rails &c; are apt to stretch the rubber,
the cement joint of which gives way and it then parts from the iron tyre. From
this arise annoyances and even the possibility of certain dangers which have prevented
the more general use of rubber tyres, in spite of the advantages which they otherwise
present.
The drawing hereunto annexed shows a sectional elevation of a wheel having a
tyre.constructed according to my invention.
On the wooden felloes A is fixed an iron tyre B raised at its edges and enlarged
at the upper part thus forming a cushion at each side. It is within this iron tyre
that the means of attachment are fixed.
They consist of one or more wires of a round triangular flat or other shape, C
passing through holes D bored at intervals in the iron tyre, either in its lower' or
lateral part. Inside this tyre the wire is raised so as to leave a free space between
it and the tyre. Outside it passes along a groove suitable: to the size and shape of
the wire and this groove is then flattened in until that side of the tyre is completely
closed either by means of rivets of T or any other, suitable shape placed. at
intervals in the iron tyre E or: by special strips of rubber F. The whole of
any one of these apparatuses is inserted in the rubber prepared for this purpose.
In this manner the rubber tyre is perfectly consolidated. It cannot be displaced
to the right or to the left since on one hand it is held by the raised sides of the iron
tyre and on the other hand it is sustained by the attachments. It cannot be
detached since by this kind of insertion its mass is connected to the iron tyre..
Having now particularly described and ascertained the nature of any said inven-
tion. and in what manner the same. is to be performed, I declare that what I
claim is.:
t
1. Securing rubber tyres to the rims of wheels by means of wires passing through
an iron rim secured to the felloes, and through the rubber tyre substantially as
described:
2: Securing rubber tyres to wheels, substantially as described with reference to
the drawings hereunto annexed:
