PROVISIONAL SPECIFICATION,
Improvements in and relating to Elastic Tyres for Wheels of
Vehicles.
I, FERNAND LÉONCE JULIEN MAQUAIRE, of 55 Boulevard Beauséjour, Paris,
in the Republic of France, Merchant, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved system of elastic tyre which can be applied
to wheels of vehicles of any kind, such as heavy and light carriages, velocipedes,
bath chairs and the like.
This system combines, with a very soft rolling movement, great simplicity and
considerable strength.
In principle my tyre comprises a rubber tube whose section is preferably made
circular but may have any form corresponding to that of the wheel rim to which it
is to be applied; this rubber tube is held upon the rim by its elasticity or by any
suitable fastening means, and it is combined with an interior ring of steel or other
material forming a spring towards the outside and keeping the rubber tube at the
desired degree of tension in order that the load may not squeeze the tyre against
the ground.
In order that my invention may be properly understood I will proceed to
describe the same with reference to the accompanying drawing, in which
Figure 1 is a transverse section showing a tyre arranged according to my said
invention.
Figure 2 represents a longitudinal section of the same.
In these two figures similar letters of reference designate corresponding parts.
By a is designated the rim of the wheel which in the case represented is a
velocipede wheel; b is a rubber tube which is fixed upon this wheel by any
suitable means, and c is an interior spring constituted by a steel rod the two
extremities of which butt against each other and are joined by a sleeve e or in any
other appropriate manner. This circular spring c is adapted to the load to be
supported and the degree of tension to be given to the tyre; instead of having
a circular section the rod which composes it may be flat, square, rectangular or
polygonal, and in certain cases it may even be replaced by a simple band of steel or
other metal.
Between the spring c and the rubber tube 6 I interpose a band d of leather,
linoleum, celluloid or other suitable material designed to protect the rubber tube
against the direct contact of the metal and to distribute more equally the pressure
exerted by the circular spring c.
The width and thickness of the band d may be adapted to the varying requirements
in practice.
It will be understood that my invention is applicable to vehicle wheels of any
kind and that according as a heavy or a light vehicle is concerned the dimensions
and detail arrangements of the several constitutive parts of the tyre may be varied
without departing from the principle of my said invention.

I, FERNAND LÉONCE JULIEN MAQUAIRE, of 55 Boulevard Beauséjour, Paris,
in the Republic of France, Merchant, 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 an improved system of elastic tyres which can be applied
to wheels of vehicles of any kind, such as heavy and light carriages, velocipedes,
bath chairs and the like.
This system combines, with a very soft rolling movement, great simplicity and
considerable strength.
In principle my tyre comprises a rubber tube whose section is preferably made
circular but may bave any form corresponding to that of the wheel rim to which it
is to be applied; this rubber tube is held upon the rim by its elasticity or by any
suitable fastening means and it is combined with an interior ring of steel or other
material forming a spring towards the outside and keeping the rubber tube at the
desired degree of tension in order that the load may not squeeze the tyre against
the ground.
In order that my invention may be properly understood I will proceed to
describe the same with reference to the drawing left with my Provisional Specifi-
cation in which
Figure 1 is a transverse section showing a tyre arranged according to my said
invention.
Figure 2 represents a longitudinal section of the same.
In these two figures similar letters of reference designate corresponding parts.
a designates the rim of the wheel which in the case represented is a velocipede
wheel; is a rubber tube which is fixed upon this wheel by any suitable means,
and c is an interior spring constituted by a steel rod the two extremities of
which butt against each other and are joined by a sleeve e or in any other
appropriate manner. This circular spring c is adapted to the load to be supported
and the degree of tension to be given to the tyre; instead of having a circular
section the rod which composes it may be flat, square, rectangular or polygonal,
and in certain cases it may even be replaced by a simple band of steel or other
metal.
Between the spring c and the rubber tube 6 I interpose a band d of leather,
linoleum, celluloid or other suitable material designed to protect the rubber tube
against the direct contact of the metal and to distribute more equally the pressure
exerted by the circular spring c.
The width and thickness of the band & may be adapted to the varying requirements
in practice.
It will be understood that my invention is applicable to vehicle wheels of any
kinds and that according as a heavy or a light vehicle is concerned the dimensions
and detail arrangements of the several constitutive parts of the tyre may be varied
without departing from the principle of my said invention.
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:
The elastic tyre for wheels of vehicles of any kind, principally characterized by

page_text: the combination of a hollow indiarubber with a circular spring giving it the desired
tension, in principle as hereinbefore described with reference to the accompanying
drawing and for the purpose specified.
