Generally and more particularly to Existing Wheels.
I, CASIMIR CONSTANT BALLIN of 20 Rue Lorraine, Paris, in the Republic of
France Manufacturer of Tubes for Artificial Flowers, do hereby declare the nature
of this invention to be as follows:-
The invention forming the subject of the present application relates to an
elastic or flexible hub of improved construction applicable to the wheels of vehicles
of every description, and more particularly to existing wheels.
Wheels of the latter class need not be changed, or undergo any essential
alteration, in order to be re-fitted in accordance with this invention, it being only
necessary to enlarge the diameter of the aperture or bore of the hub and to reduce
its length, to adapt it for the reception of the improved flexible device.
The flexible arrangement enables the wheel to be strengthened at its weak or
reduced part, its centre being tightly compressed between two metal parts which
protect it from injury.
Besides, a wheel fitted with the elastic device possesses great strength, whilst
its elasticity is better distributed over its circumference, all shocks or thrusts being
relieved by an india-rubber cushion interposed between the wheel and the axle
journal which consequently is not liable to be broken.
This arrangement also obviates the inconveniences attending the application
of india-rubber to the felloe of the wheel; the rubber so applied being liable to
rapid deterioration and apt to cause the wheels to slip upon wet roadways.
The invention will be clearly understood by reference to the accompanying
drawings which show by way of example only, an arrangement carried out in
accordance with my invention.
In the drawings
Figure 1 is an elevation of an existing wagon or carriage wheel to which the
improved flexible hub arrangement is applied.
Figure 2 is a horizontal section thereof taken on the line 1-2 of Figure 1.
Figure 3 is a vertical section separately of the flexible hub shown at Figures 1
and 2 but drawn to an increased scale.

The method of applying the improved flexible arrangement to the wooden hub
of an existing wheel, say, to the wheel of a wagon or carriage as is assumed to
be the case in the example given at Figures 1 to 3 is as follows:-
The outside parts of the wooden hub, are 'first removed so as to reduce its
length and the portion a thereof only is retained.
The diameter of the opening or bore through which the axle journal passes is
then enlarged for the reception of the improved flexible device.
After interposing the part 6 of the india-rubber sleeve between the bushing c
of the hub and the portion d of the casing, these two halves of the device are
inserted into the enlarged bore of the wooden hub a and a cap e is then screwed
on to the part d of the casing.
After inserting the part 61 of the india-rubber sleeve between the portions c¹
and of the bushing and casing respectively, these pieces are united by screwing
together the corresponding parts c and c¹; and, upon screwing the cap
the part of the casing, the wooden hub a will be firmly compressed by the casing
and the hoops will be prevented from shifting.

By these means a wheel of great flexibility and strength is obtained whilst no
change need be made in the usual method of lubrication.
In applying the improved arrangement to the metal wheels of motor carriages,
as exemplified at Figures 4 to 6, the india-rubber sleeve b is interposed between
the wheel bushing and the outer case 9 wherein the spokes / are set.
The portion c¹ of the bushing is screwed into the corresponding part c after which
the cap is screwed into the interior of the case g.

Where the improved flexible hub is employed, the wheel may be fitted with
balls adapted to roll around the journal or arm 7 of the axle.
It will be understood that the shapes and dimensions of the parts, the details
of construction and the materials employed in the manufacture of the improved
device may vary, without departing from the principle of the invention.

An Improved Flexible Hub applicable to the Wheels of Vehicles
Generally and more particularly to Existing Wheels.
I, CASIMIR CONSTANT BALLIN of 20 Rue Lorraine, Paris in the Republic of
France, Manufacturer of Tubes for Artificial Flowers 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 forming the subject of the present application relates to an elastic
or flexible hub of improved construction, applicable to the wheels of vehicles
of every description, and more particularly to existing wheels..
Wheels of the latter class need not be changed or undergo any essential altera-

page_text: tion in order to be re-fitted in accordance with this invention, it being only
necessary to enlarge the diameter of the aperture or bore of the hub and to reduce
its length to adapt it for the reception of the improved flexible device.
The flexible arrangement enables the wheel to be strengthened at its weak or
reduced part,. its centre being tightly compressed between two metal parts which
protect it from injury.
Besides, a wheel fitted with the elastic device possesses great strength, whilst
its elasticity is better distributed over its circumference all shocks or thrusts being
relieved by an india-rubber cushion interposed between the wheel and the axle
journal, which consequently is not liable to be broken.
This arrangement also obviates the inconveniences attending the application of
india-rubber to the felloe of the wheel; the rubber so applied being liable to rapid
deterioration and apt to cause the wheels to slip upon wet roadways.
The invention will be clearly understood by reference to the drawings accompany
my Provisional Specification which show by way of example only, an arrangement
carried out in accordance with my invention..
In the drawings,
Figure 1 is an elevation of an existing wagon or carriage wheel to which the
improved flexible hub arrangement is applied;
Figure 2 is a horizontal section thereof taken on the line 1-2 of Figure 1.
Figure 3 is a vertical section separately of the flexible hub shown at Figures 1
and 2 but drawn to an increased scale;
Figure 4 illustrates the manner of applying the flexible hub arrangement to
the metal wheels of motor cars.
Figure 5 is a horizontal section taken on the line 3-4 of Figure 4, and
Figure 6 is a vertical section separately of the elastic hub shown at Figures 4
and 5 but drawn to an increased scale.
In the several figures like parts are indicated by similar letters of reference.
The method of applying the improved flexible arrangement to the wooden hub
of an existing wheel-say to the wheel of a wagon or carriage as is assumed to
be the case in the example given at Figures 1 to 3 is as follows:-
The outside parts of the wooden hub are first removed, so as to reduce its length
and the portion a thereof onlv is retained.
The diameter of the opening or bore through which the axle journal passes
is then enlarged for the reception of the improved flexible device.
After interposing the part 6 of the india rubber sleeve between the bushing c
of the hub and the portion d of the casing these two halves of the device are
inserted into the enlarged bore of the wooden hub a; and a cap e is then screwed
on to the part d of the casing.
After inserting the part 61 of the india rubber sleeve between the portions c¹
and of the bushing and casing respectively, these pieces are united by screwing
together the corresponding parts c and c¹, and, upon screwing the cap el on to
the part of the casing, the wooden hub a will be firmly compressed by the
casing and the hoops f will be prevented from shifting.
By these means a wheel of great flexibility and strength is obtained whilst no
change need be made in the usual method of lubrication.
In applying the improved arrangement to the metal wheels of motor carriages
as exemplified at Figures 4 to 6, the india rubber sleeve is interposed between
the wheel bushing c and the outer case 7 wherein the spokes h are set. The
portion c¹ of the bushing is screwed into the corresponding part c, after which the
cap i is screwed into the interior of the case g.
Where the improved flexible hub is employed, the wheel may be fitted with
balls & adapted to roll around the journal or arm 7 of the axle.
It will be understood that the shapes and dimensions of the parts, the details
of construction and the materials employed in the manufacture of the improved
device may vary without departing from the principle of the invention
