Improvements in Tyres for Vehicle Wheels.

page_text: I, EMILE POIZOT, of 101, Faubourg St. Denis, Paris, France, Engineer, do
hereby declare the nature of this invention to be as follows:-
The subject of the present invention is an arrangement or method of fixing
in place the tyres of carriage wheels.
The tyre is composed of two twin bands against which are placed segments of
steel or of very hard wood having a wedge shaped section. These segments are
curved to the same radius as the wheel, and have at their extremities grooves or
recesses to receive the head of a T-headed bolt which is placed between two
adjacent segments. These bolts pass through the felloe of the wheel and are
tightened up by nuts placed on the interior of the said felloe, thus effecting a
pressure towards the centre of the wedge shaped segments and insuring the
fixation of the tyre.

Improvements in Tyres for Vehicle Wheels.
I, EMILE POIZOT, of 101, Rue du Faubourg St. Denis, Paris, in the Republic
of France, Engineer, 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:-
The present invention relates to the tyres of wheels for vehicles, and more
especially to a practical arrangement for fixing or securing the said tyres in
position.
The annexed drawing, given by way of example, illustrates one method of
carrying the said invention into practice.
In this drawing:-
-
Fig. 1, is a section of a felly or rim of a wheel, provided with the said
arrangement for fixing or securing the tyre in position, on a plane passing
through the axis of the said wheel.
Fig. 2, is section on a plane perpendicular to the same axis of a portion of
the said felly or rim.
Upon a wooden felly or rim E having a smooth external surface, is mounted a
Paine 71

page_text: band F formed of U shaped iron, and upon this a band of caoutchouc or india-
rubber H is placed.
Upon this latter band are arranged two rings or circular pieces D), 1), which
constitute the tyre proper and are separated by a circular space or clearance
into which the segmental pieces A, which are formed of steel or of very hard
wood, are inserted. These segmental pieces are fixed between the rings or
circular pieces D, D¹, by means of bolts M, the heads of which are T shaped,
and which rest or bear in the recesses of two adjacent segmental pieces A. These
bolts pass through the caoutchouc or indiarubber band, the U shaped iron and the
felly or rim of the wheel, and can each be tightened up as desired by means of a
nut X on the interior of the said felly or rim.
The rings D, D¹, are constructed of india rubber or of any other suitable
material.
It will be readily seen from an inspection of the drawing, that the more the
nuts X are tightened up, the more the wedge shaped segmental pieces A will
be drawn down and the more the rings or circular pieces D, D', will be forced
or pressed against the flanges of the U shaped iron.
This method of fixing or securing is very efficacious and very expeditious, and
can be applied to all tyres.
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. An arrangement for securing or fixing in place tyres to or upon their
wheels, characterized by a band of shaped iron fitted upon the wheel to be
served, by a band of indiarubber applied upon the first. by two rings or circular
pieces D, D¹, forming the tyre and leaving between them a circular space or
clearance in which steel or hard wood segments are inserted, and by T headed
bolts holding the said segments in place and capable of being tightened at will
upon these latter by means of nuts placed on the interior of the felly or rim,
with the object of effecting the tightening or pressing as desired, of the rings or
circular pieces D, D¹, against the flanges of the U shaped iron hereinabove
mentioned, for the purpose of insuring a rapid and efficient fixation of the tyre.
2. In an arrangement for fixing or securing tyres such as that claimed in the
first claim, the arrangement of a wooden felly or rim E with a smooth exterior
surface, of a U shaped iron F fitted upon the said felly or rim, of a band of
caoutchouc or indiarubber H covering the said U shaped iron of two rings or
circular pieces D, D¹, having between them a circular space or
clearance of segmental pieces A inserted in the said clearance,
held in position by bolts M which can be tightened up at will by means of nuts X.
in order to insure the pressure of the said rings or circular pieces D, D', against
the flanges of the U shaped iron and secure the fixation of the tyre.
and
3. An arrangement for fixing or securing tyres to the fellies or rims of wheels,
substantially as described in the above specification and illustrated in the accom-
panying drawing.
