LA SOCIÉTÉ BALLIN ET CIE, Manufacturers of Elastic Wheel-naves, of 5, Rue de
Chateaudun, Paris, in the Republic of France, do hereby declare the nature of
this invention to be as follows:
This invention relates to improvements in anti-vibratory, elastic náves for the
wheels of carriages and other vehicles.
The said invention is chiefly characterized by the interposition between the
wheel-nave proper, which carries the spokes of the wheel, and the revolving
socket supported on the axle, of an elastic, non-metallic pad or cushion composed
of a body of soft material, such, for example, as caoutchouc, to diminish the jolts,
shocks and mechanical vibrations and noises.
This pad or cushion is advantageously formed by two series of caoutchouc
balls arranged concentrically around the central socket and in the first place
tightly packed in a chamber or race, the said pad or cushion being made in sec-
tions for the purpose of permitting the movements of compression at the moment
of the shock to be effected by simple displacement of the elastic material itself
and not by rubbing of this material on the walls which enclose it as is the case
with a continuous ring.
To enable the said invention to be readily understood, we have shown in the
accompanying drawings, but as an example only, one form of the said elastic
nave.
In the said drawings
Figure 1, shows, in vertical longitudinal section, the nave of an ordinary
wooden wheel having our improvements applied thereto.
.
Figure 2 shows a vertical transverse section of the same.
Figure 3 is a similar view to Figure 1, illustrating the method of subjecting
the balls to a preliminary compression during construction.
Figure 4 shows a detail of construction.
Like letters indicate corresponding parts throughout the drawings.
In principle our apparatus is composed of an exterior socket constructed in
two parts a, a¹ in such a manner as to permit the said parts to be inserted in

page_text: the wooden nave 6 carrying the spokes and fixed and secured on the said nave
by coach-screws or other fastening devices. In the interior of the parts a and a¹
forming the said socket, segmental recesses c are arranged to receive the spherical
caoutchouc balls d. Cones e, e¹ are provided to secure and support the balls
which are lodged in the recesses f.
These cones e, el are threaded and keyed on the socket or sleeve g which turns
on the axle, the cone e being fixed and resting against a shoulder near one end
of the said socket g, and the cone e¹ being free to slide but not to turn relatively
to the said socket or sleeve g, and being held in place by the locking-nut h.
The adjacent faces of both the nut h and the cone have similar toothed racks
with inclined teeth (Figure 4) cut thereon.
The teeth of the rack on the nut h incline in an inverse direction to the screw-
thread of the said nut, so that, when the cone e¹ is driven right home by the
nut and the teeth of the racks are in engagement, it is absolutely impossible
for the nut to work loose.
In Figure 3 we have shown, in broken lines, the necessary appliances for
putting on and taking off the nut h. These appliances comprise a bridle i and
a counter bridle k intended to hold up the socket.
A screw is provided to press on the movable cone e¹ to release its rack from
the corresponding rack on the nut and consequently to permit this latter to
turn for screwing together or unscrewing.
The pressure obtained by this nut ought to be sufficient to compress the
balls to an amount varying according to the depth of the teeth of the rack. On
the release of the nut 7, the cone el is pressed by the elasticity of the balls - so
as to bring the teeth of the racks on the nut h and cone c¹ into proper engagement.
These arrangements offer the following advantages
1st. By reason of each ball being held in its own recess, each of the said balls
in turn, is compressed when it passes beneath the socket during the rotation of
the wheel; while on the contrary the uppermost balls are somewhat relieved
of pressure. When the balls pass along the sides they are inflected without slip-
ping in their recesses.
2nd. By reason of the clearly determined position of the series of clastic balls
and their distance apart, great stability of the wheel is obtained without de-
tracting from the appearance of the wheel and whilst permitting the vertical,
lateral and oblique shocks to be absorbed.
3rd. The certainty of the wheel driving the socket without fear of this part
sliding on the caoutchouc.
4th. In the event of damage one or more balls can be easily replaced and at
a low cost instead of requiring a complete new outfit.
It is to be understood that the arrangements herein before described can be
also applied to ball-bearing hubs or to metallic wheels with tension spokes as
well as to motor-car-wheels or the wheels of velocipedes or of ordinary animal
traction vehicles. Also the balls may be spheres, polyhedrons or even cylinders
of india-rubber or other suitable elastic material having analogous properties
We also wish it to be understood that we may vary the form, size, details and
materials employed in the construction of our apparatus without departing from
the nature of our said invention.

page_text: Improvements in Anti-vibratory Elastic Naves for Vehicle-wheels,
We, LA SOCIÉTÉ BALLIN ET CIE, Manufacturers of Elastic Wheel-naves, of
5, Rue de Chateaudun, Paris, in the Republic of France, 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:
This invention relates to improvements in anti-vibratory, elastic naves for the
wheels of carriages and other vehicles.
-
The said invention is chiefly characterized by the interposition, between the
wheel-nave proper, which carries the spokes of the wheel, and the socket revolv-
ing on the axle, of an elastic, non-metallic pad or cushion composed of a body
of soft material, such for example, as caoutchouc, to diminish the jolts, shocks
and mechanical and sonorous vibrations.
This pad or cushion is advantageously formed by two series of caoutchouc
balls arranged concentrically around the central socket and, in the first place,
tightly held in a chamber or race; the said pad or cushion being made in sections
for the purpose of permitting movements of compression at the moment of the
shock to be effected by simple displacement of the elastic material itself and not
by the rubbing of this material on the walls which enclose it as is the case with
a continuous ring.
To enable the said invention to be readily understood, we have shown in the
drawings, left with our Provisional Specification, but as an example only, one
form of the said elastic nave.
In these drawings:-
Figure 1 shows in vertical longitudinal section, our arrangement in its appli-
cation to the nave of an ordinary wooden wheel.
Figure 2 shows a vertical transverse section of the same;
Figure 3 is a similar view to Figure 1, illustrating the method of subjecting
the balls to a preliminary compression during construction.
Figure 4 shows a detail of construction.
Like letters indicate corresponding parts throughout the drawings.
Our apparatus comprises an exterior socket constructed in two parts a, a¹ in
such a manner as to permit the said parts to be inserted in the wooden nave b
carrying the spokes and fixed and secured on the said nave by "wood" or coach
screws or other fastening devices.
In the interior of the parts a and a¹ forming the socket, segmental recesses c
are arranged to receive the spherical caoutchouc balls d.
Cones e, el are provided for holding and retaining the balls, which are lodged
in recesses therein.
These cones e e¹ are slid or threaded and keyed on the socket or sleeve which
༡
turns on the axle, the cone e being fixed and resting against a shoulder forming
an abutment, and the cone e¹ being capable of sliding and not turning on the ring
or socket g, but held in place by the locking nut h; this nut rests on the cone e¹
by means of a rack with inclined teeth, Figure 4, of which there is one on each
of the two pieces. The teeth of the rack on the nut h incline in an inverse
direction to the screw-thread on the said nut so that, when the cone e¹ is driven
right home by the nut and the teeth of the racks are in engagement with each
other, it is absolutely impossible for the nut to work loose.
In Figure 3 we have shown, in broken lines, the necessary appliances for
putting on and taking off the nut h. These appliances comprise a bridle i and
a counter-bridle k serving to hold up the socket.

page_text: A screw-threaded sleeve is provided to press on the movable cone e¹ to release
its rack from the corresponding rack on the nut h and consequently to permit
this latter to turn either for screwing it up or for unscrewing it.
The pressure obtained by this'nut l'ought to be sufficient to compress the balls
to an amount varying according to the depth of the teeth of the rack. On the
release of the nut the cone e¹, pressed outwards by the elasticity of the balls,
returns so as to bring the teeth of the racks on the nut h and cone e¹ into proper
engagement with each other.
These arrangements offer the following advantages:
1.33
1st. By reason of the division of the pad or cushion, into a number of balls,
each ball being held in its own recess, each of the said balls in turn, is .com-
pressed when it passes beneath the socket during the rotation of the wheel;
while on the contrary, the uppermost ball is somewhat relieved of pressure,
When the balls pass along the sides, they are inflected without slipping in their
recesses.
2nd. By reason of the clearly determined position of the two elastic systems
and their distance apart, a sufficiently great stability of the wheel is obtained
in its place; this prevents interference with the appearance of the carriage whilst
permitting the vertical, lateral or oblique shocks to be absorbed.
3rd. The certainty of the wheel driving the socket without fear of this part
sliding on the caoutchouc.
4th. In the event of damage, one or more balls can be easily replaced at a low
cost instead of requiring a complete new outfit.
or wires
It is to be understood that the arrangements herein before described can be
also applied to a ball-bearing hub or to a metallic wheel with tension spokes
as well as to motor-car wheels or to the wheels of velocipedes or. of
ordinary animal traction vehicles. Also the balls may be spheres, polyhedrons
or even cylinders of indiarubber or other suitable elastic material having analo-
gous properties.
We also wish it to be understood that we can somewhat vary the form, dimen-
sions, details or materials employed in the construction of our apparatus without
departing from the nature of our said invention.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:
An anti-vibratory elastic wheel-nave for the wheels of carriages and other
vehicles, characterized by the interposition, between the wheel-nave proper
carrying the spokes and the socket or sleeve which turns on the axle, of an
elastic pad or cushion of soft material such as a series of caoutchouc balls serving
to prevent or diminish the transmission of jolts, shocks and vibrations to the
body of the vehicle, substantially as herein before described with reference to
the drawing.
