PROVISIONAL SPECIFICATION.
An Improvement in connection with the Wheels of Bioyoles, which
may be Applied to other Vehicles.
CHARLES PATRICK JOSEPH FITZSIMON No. 6 Vincent Terrace Glasnevin
Co. Dublin Secretary to a Public Company do hereby declare the nature of this
invention to be as follows:-
A central circular box as in an ordinary wheel to which the spokes are fastened.
Internally this box contains a spring or an air chamber to act as such of india
rubber or other suitable substance formed round a spindle which passes from end to
end through the centre of the box. The box is fitted at both ends with grooves
and these ends are covered with caps having pins or cogs which work in the grooves.
The axle passes through the centre of the spindle and the spindle rests on the
spring or air chamber before mentioned.

An Improvement in connection with the Wheels of Bicycles, which
may be Applied to other Vehicles.
I, CHARLES PATRICK JOSEPH FITZSIMON formerly of No. 6, Vincent
Terrace, Glasnevin, County Dublin but now of 37, Jolliffe Street, Prince's Road,
Liverpool in the County of Lancaster, Secretary to a Public Company, 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 wheels of bicycles and other vehicles,
and has for its main object the arrangement of a box or cover inside the hub of the
wheel, the said box or cover to contain an elastic substance such as an india rubber
tube inflated with air, or containing springs of any suitable form whereby resiliency
is produced in the hub or nave of the wheel.
Referring to the accompanying drawings:-
Figure 1 is a side sectional view:
Figure 2, a cross sectional view; and
Figure 3, a detail view showing my improvements.
In these―
A is a central circular box, as in an ordinary wheel, to which the spokes a are
fastened. B is the inner box or chamber containing the elastic substance to act as
a spring, and the parts B' attached thereto from a hollow axle on which the hub of
the wheel rotates. In the drawing, a pneumatic tube is shown, which is supported
by a chair or frame C resting on a non-rotative support D. This invention is not
confined to the exact form of the inner chamber B or chair C shown in the
drawings, as the former may be arranged below the support D, or it may surround
the same, and the shape of the chair or frame would be altered to suit.
support D is preferably square and passes through both the inner and outer
casings A and B, and to the ends of the same the forks or framework (in the case
of bicycles and the like) are fixed. E is a slot, shown best in Figure 3, to allow
of the vertical movement of the support D.
The

page_text: The action of the device is simply this, that, when any weight is brought to bear
on the bicycle or other vehicle, the air or other elastic substance is compressed
similarly to the ordinary pneumatic tyre, and, if used in combination with such, a
greater resiliency is produced.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The improvement connected with wheels of bicycles or other vehicles, consisting
in a non-rotative support, a hollow axle surrounding same, also non-rotating and
resting on the said support with the interposition of an elastic substance and the
wheel hub rotating on said axle, substantially as described.
2. The arrangement of a slot E to allow of the vertical movement of the
support D while the bicycle or other vehicle is in motion, substantially as
described.
3. The general arrangement and construction of parts forming the object of this
invention substantially as described and shown on the accompanying drawing.
Dated this 10th day of March 1894.
