Improvements in and relating to Elastic Tyres.
I, JULES NOEL DAGES, of 6, Rue de Chateaudun, Paris, in the Republic of
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to an improved wheel-tyre characterized principally by
the employment of a vibrator ring or hoop which at the same time supports the
outer casing or cover of the tyre internally.
My invention will be readily understood from the following description with
reference to the accompanying specimen drawing, in which,
Figure 1 shows my improved tyre as constructed more particularly for use on
velocipedes;
Figure 2 is a modification thereof.
Figure 3 shows a complete tyre for use on cabs.
Figure 4 shows a tyre for use on omnibuses.
As shown in Figure 1 of the drawing, my improved tyre consists, essentially,
of a metallic rim or felloe a which holds the cover b in position by means of its
ribs or projections c, in each of which is arranged a cable, cord or the like d.
The cover b, which is made with longitudinal grooves e, is provided internally
with a lining of fabric q, arranged on the bias, and with a tissue of tape or
ribbon, or plaited or woven whalebone r, let into or moulded in the india-rubber.
In the interior of the rim a is placed a ring f of wood which prevents the rim
from being distorted under the tension of the spokes g and resists the shearing
action of the heads h of the said spokes which rest against a metallic ring i. The
rim and the ribs or projections of the cover, as well as a part of the said cover
are protected by auxiliary felloes / arranged one on one side and the other on the
other side of the said cover and which are secured to the ring f by means of
screws. In the interior of the cover b is arranged a vibrator m formed from
strips of wood arranged with the grain running in different directions or by
coiling or rolling on itself a strip of wood coated with glue. The ring m, thus
produced, is formed into the desired shape as regards cross-section and then
covered with cloth; it preferably also comprises a metallic ring o and finally a
crown of steel p arranged on the inside. From what has been said above, it will
be seen that the rim or felloe a, the ring f and the auxiliary felloes offer an
elastic and strong resistance and prevent the wheel from distortion whilst
obviating the shearing action of the spoke-heads.
-
The vibrator-ring m stretches the cover b and ensures elasticity in rolling. In.
the modification shown in Figure 2, the vibrator-ring or hoop is formed by a
primary ring receiving a cable v. This ring is let into a second ring u provided
with cables t and finally three thicknesses of wood s complete the hoop. In the
arrangement shown in Figure 3, for use on the wheels of cabs, the wood ring f
is provided with metal wires z rolled up in a groove. This arrangement moreover
comprises lugs or side pieces y secured in position by means of screws y' and
serving to support the cover b laterally.
The two metallic felloes a and are retained on the ring f by means of screws 11.

page_text: The first ring of the vibrator-ring or hoop contains three cables, the second
ring is reinforced by four cables t, and finally a thickness of wood s, completes
the hoop.
In the arrangement for omnibus wheels, shown in Figure 4 of the drawing, the
first wooden ring is reinforced internally by a metallic ring in which is
the cable v. Between the ring and the ring u, are metallic rings u engaging
in grooves as shown, and similarly for the other wooden rings, except the last,
which does not have any.
The forms, details, accessories, materials and dimensions of my tyre can be
modified without in any way departing from the nature of my invention.
I can also make my vibrator ring or hoop of any suitable elastic material, such
as metals, wood, vegetable material, etc.

I, JULES NOEL DAGES, of 6, Rue de Chateaudun, Paris, in the Republic of
France. Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement: —
The present invention relates to improvements in elastic tyres or to a novel
method of tyreing wheels, characterized chiefly by a vibrating circle or hoop which
at the same time keeps in position interiorly the covering or envelope of the
tyre. My invention will be well understood by the following description with
reference to the accompanying drawings, in which :-
Figure 1, shows my method of tyreing intended especially for cycles.
Figure 2, is a modification of Figure 1.
Figure 3, shows a tyre intended for cabs or other light vehicles.
Figure 4, depicts a tyre for use with omnibuses or other heavy vehicles.
As may be seen from the figures of the drawing, my system of tyreing consists
essentially of a metal counter felloe a which retains the envelope
in which there is placed a rope d.
by its lugs c
cut
The envelope b, provided with longitudinal channels e, is lined with cloth
on the bias or diagonally and by a tissue of ribbons or twisted and plaited whale-
bones steeped in caoutchouc or gutta-percha. On the inside of the counter
felloe a, there is placed a wooden hoop f which prevents the counter felloe from
being distorted by the tension of the spokes g, and it prevents the necessity of
cutting off the heads of the spokes h fixed in a metal circle or hoop i. The counter
felloe a and the lugs c and also a portion of the envelope are protected by
a felloe fixed to the hoop fi by means of screws as shown in Figure 3. On
the inside of the envelope there is placed a circular vibrator m formed of flat
strips of wood arranged on one another flatwise, or laminated, or else by rolling
up one long strip of wood soaked in glue. The circle or hoop m thus obtained
is made of the form desired in cross-section and then covered with cloth; and
it may also comprise a second metal endless band o, and, finally, a steel locking-
hoop or strengthening hoop placed in the inside. From the foregoing it will
be seen that the felloe 1, the hoop f and the counter-felloe a form an elastic and

page_text: sensitive resistance, which prevents the wheel from being distorted, and obviates
the necessity of cutting off the heads of the spokes.
The vibrating hoop m stretches the envelope b and assures an elastic action. In
the variation shown in Figure 2, the vibrating hoop is formed of a primary
circle receiving a cord v. This circle is fitted into a second u provided with
cords and finally three thicknesses of wood s completes the arrangement. In
the arrangement for the wheels of cabs, shown in Figure 3, the wooden circle or
rim f is fitted with wires z inserted in grooves in the felloe. This arrangement
comprises clamps y fixed by means of the screw y¹, and intended to hold the
cover b laterally.
The two metal felloes a and are held on the hoop f¹ by means of the screws 1.
The first hoop of the vibratory hoop contains three cords v, the second hoop u
is strengthened by four cords t and finally a bed of wood s completes the hoop.
In the arrangement for omnibus or other heavy vehicle wheels shown in Figure 4
of the drawing, the first wooden hoop is strengthened interiorly by a metal
hoop in which is the cable >. Between the hoop r and the hoop u there are
metal hoops u fitted in grooves and it is the same with the other wooden hoops
save and excepting the last which has no grooves.
The forms, details, accessories, materials, and sizes of the parts comprised in
my system of tyreing, can be changed without in any way altering the principle
of my invention.
I also reserve the right to make my vibratory hoop of any material, such as:-
metals, wood, vegetable substances etc., that will afford the necessary elasticity.
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:-
A wheel for a vehicle, characterized by a wooden hoop f receiving the spokes g
a metal felloe and counter-felloe and a respectively which carry an elastic cover b
in which there is a vibratory hoop m preferably of wood, this hoop being formed
of several thicknesses and being strengthened by cords or wires in such a way
as to stretch the rubber envelope, the whole being substantially as described and as
shown in the accompanying drawings.
