I, THÉODORE STERNÉ, of 49, Rue de la Victoire, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as
follows;-
The invention has for its object a novel combination of parts forming an im-
proved elastic tyred wheel.
For this purpose
employ a felloe of any suitable shape and material and
having an annular space or recess to receive a spring arrangement, other than a
pneumatic tube, constituting the elastic element of the tyre. Around this spring
arrangement or elastic element is placed the tyre or outer cover which is of such
size as to put a considerable amount of pressure on the elastic element and of
such shape and porportions as to fit closely the sides or the outer edges of. the
space in the felloe and to enter and project a suitable distance from the latter.
The spring arrangement or elastic element may be of any suitable construction.
As example I would mention that it may be formed of a series of curved ribbon
steel springs rivetted to a metal base band and projecting outwards therefrom.
These springs overlap each other at their outer ends where if desired they may
be connected to a band of metal or other material. Or the springs may consist of
ribbon steel having a flat portion by which they are rivetted to the base band and
a helically coiled portion overlapping and resting on the flat part of an adjacent
spring. These latter springs are rivetted to a base band as above described.
The space around the felloe may be rectangular so as to fit somewhat closely
the base and sides of the elastic element in which case the tyre or outer cover
will fit closely such space but will be entirely above the outer surface of the
elastic element.
Or the space around the felloe may be somewhat wider than the elastic element
and the edges thereof turned inwards in which case the type or outer cover whilst
partially fitting such space will be recessed to fit the outward part of the spring
element.
In either or any case the form of the parts is so devised that the spring element
whilst having full freedom of action in a vertical direction is held securely
against sideway or torsional motion. It will be evident that the elastic element
may be constructed otherwise than as above described and that the running sur-
face of the tyre or outer cover may be of any suitable shape.
An elastic tyred wheel of the character above described will also exclude dirt,
stones and other foreign matter from access to the spring element.

page_text: I, THÉODORE STERNÉ, of 49, Rue de la Victoire, 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 invention has for its object a novel combination of parts forming an in-
proved elastic tyred wheel.
For this purpose I employ a felloe of any suitable shape and material and
having an annular space or recess to receive a spring arrangement, other than a
pneumatic tube, constituting the elastic element of the tyre. Around this spring
arrangement or elastic element is placed the tyre or outer cover, which is of such
size as to put a considerable amount of pressure on the elastic element, and of
such shape and porportions as to fit closely the sides or the outer edges of the
space in the felloe and to enter or surround and project a suitable distance from
the latter.

In order that my invention may be more readily understood, I will proceed,
aided by the accompanying drawings, more fully to describe the same.
Figs. 1, 2 and 3 are cross sections of three tyres for velocipedes made according
to my invention.
Fig. 4 is a portion of one of the arrangements of elastic fitting which I use.
Fig. 5 is a similar view of a different form of elastic fitting.
My improved elastic tyred wheel comprises a felloe A of suitable shape made
of wood, an example of which is shown at Fig. 1, or of metal, examples of which
are shown at Figs. 2 and 3. These felloes are hollow to receive the spring
arrangement constituting the elastic element of the tyre. The spring arrange-
ment or elastic_element may be of any suitable construction.
As examples I would tion that it may, as represented at Fig. 4, be formed
of a series of curved ribbon steel springs B rivetted to a metal base band C and
projecting outwards therefrom. These springs B overlap each other at their
outer ends where if desired they may be connected to a band E of metal or other
material. Or the springs may consist, as represented at Fig. 5, of ribbon steel
having a flat portion B by which they are rivetted to the base band C¹ and a
helically coiled portion B2 overlapping and resting on the flat part B₁ of an adja-
cent spring.
The space around the felloe may be rectangular as shown at Figs. 1 and 3, so
as to fit somewhat closely the base and sides of the elastic element as shown at
Fig. 1, in which case the tyre or outer cover D will fit closely within such space,
but will be entirely above the surface of the elastic element. Or the space around
the felloe may be somewhat wider than the elastic element and the edges of the
same turned inwards, as shown at Fig. 2, in which case the tyre or outer cover D,
whilst partially fitting such space, will be recessed to fit the outward part of the
spring element. Or as shown at Fig. 3, the felloe may be shallower than those
shown at Figs. 1 and 2, in which case the spring element is surrounded by a
tyre F stretched around the same, which latter and the otherwise exposed sides
of the spring arrangement may be covered by an outer cover I completely en-
closing the same and overlapping the edges of the felloe, to which it is attached
in any convenient manner.
In either or any case the form of the parts is so devised that the spring element,
whilst having full freedom of action in a vertical direction, is held securely
against sideway or torsional motion. It will be evident that the elastic element

page_text: may be constructed otherwise than as above described, and that the running
surface of the tyre or outer cover D may be of any suitable shape.
An elastic tyred wheel of the character above described will also exclude dirt,
stones and other foreign matters from access to the spring element.
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 elastic tyred wheel for velocipedes or other vehicles characterised by the
combination with a hollow felloe of suitable shape, of a conveniently formed
spring element lodged or encased in the felloe, and a tyre or outer cover stretched
around the spring arrangement and fitting within the hollow of the felloe, sub-
stantially as herein set forth.
2. An elastic tyred wheel for velocipedes or other vehicles characterised by the
combination with a hollow felloe of suitable shape, of a conveniently formed
spring element lodged in and fitting the interior of the felloe, and a tyre or outer
cover stretched around the spring arrangement and fitting within the hollow of
the felloe, substantially as herein set forth.
3. An elastic tyred wheel for velocipedes or other vehicles characterized by the
combination with a shallow hollow felfoe, of a spring arrangement partially enter-
ing said hollow felloe, and a tyre stretched around said spring arrangement, sub-
stantially as herein set forth.
4. An elastic tyred wheel for velocipedes or other vehicles characterised by the
combination with a shallow hollow felloe, of a spring arrangement partially enter-
ing said hollow felloè, a tyre stretched around said spring arrangement, and an
outer cover completely enclosing the tyre and spring arrangement and overlap-
ping the edges of the felloe, substantially as herein set forth.
5. An elastic tyred wheel for velocipedes or other vehicles characterised by the
combination with a hollow felloe of suitable shape, of a spring arrangement
formed with overlapping spring blades attached to a hoop and lodged or encased
in the felloe, and a tyre or outer cover stretched around the spring and encased
in the hollow of the felloe or overlapping the edges of the latter, substantially
as herein set forth.
