PROVISIONAL SPECIFICATION.
An Improved Wheel for Velocipedes and other Vehicles.
We, EDWARD CASTILDINE MARTIN of "Heatherlea," Caulfield near Rosstown
Station in the Colony of Victoria Journalist and ARTHUR TURRALL, of
No. 31 Queen Street, Melbourne in the Colony of Victoria, Manufacturer, do
hereby declare the nature of this invention to be as follows:--
The object of this invention is to provide a wheel for velocipedes and other
vehicles which whilst possessing the advantages of a wheel fitted with a pneumatic
tyre will not be liable to puncture and other similar damage.
According to this invention the wheels are constructed with two concentric rims
so as to leave an annular space between them.
This annular space is fitted with springs which take up any jar cominunicated
to the outer rim and thus ensure the vehicle travelling more smoothly an I
easily.
The inner rim is fitted with spokes in the ordinary way whilst the outer rim has
a solid rubber or other tyre. The nipples used for securing the ends of the spokes
to the inner rim may also be used for fastening the springs to it. These said
springs may be formed of flat steel and may be arranged to project from the inner
rim approximately at a tangent thereto.
They are long enough to extend from the point where they first contact with the
uter rim of the wheel to the point where the next spring contacts therewith and
the end of each spring may be fitted under and secured by the bolt or nipple which
secures the next spring in position, thus forming two complete rings and thereby
materially strengthening the wheel.

We, EDWARD CASTILDINE MARTIN of "Heatherlea," Caulfield near Rosstown
Station in the Colony of Victoria, Journalist and ARTHUR TURRALL of
No. 31, Queen Street, Melbourne in the Colony of Victoria, Manufacturer, 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 object of this invention is to provide a wheel for velocipedes and other light
vehicles which whilst possessing the advantages of a wheel fitted with a pneumatic
tyre will not be liable to puncture.

page_text: According to this invention the wheels are constructed with two concentric rims
so as to leave an annular space between them.
This annular space is fitted with tangent springs which take up any jar com-
municated to the outer rim and thus ensure the vehicle travelling more smoothly
and easily, as will be readily understood on reference to the accompanying drawing
which is a sectional elevation of part of a wheel constructed according to this
invention.
A represents the inner and B the outer concentric rims, whilst CC represent
the flat steel tangent springs which are inserted in the annular space between said
concentric rims one end of each of said springs being secured to the inner rim A
and the other end to the outer rim B.
The spokes D extend through the inner rim A and are secured (by being
rivetted over at their ends or otherwise) to the springs C small discs or washers d
being fitted under the heads of said spokes in order to strengthen the springs
where said spokes pass through them.
Means, such for instance as the nipples indicated at d, are provided for
adjusting the teusion of these spokes and small screw threaded bolts E may b:
passed through the springs C C and be fitted with correspondingly threaded nuts e
as shown in order to adjust the tension of the different springs C, which latter are
secured to the outer rim B by the small bolts c' and to the inner rim A by the
bolts whilst at the same time said springs are long enough to extend to the
adjusting bolt E of the next springs that each adjusting bolt will assist in
retaining two springs in position. A piece of cork or other easily compressible
material may be inserted as indicated at F between the upper end of each spring
and the outer rim B partly to assist in securing the spring in position and partly
to prevent dirt or grit finding a lodgement.
A pair of lugs or brackets G and H are secured one to the inner rim and the
other to the outer rim.
These lugs or brackets are connected together by a wire or rod I having one of
its ends screw threaded and passed through a correspondingly screw threaded hole
or nut in the bracket G so as to enable a strain to be put on such rod and through
the rims on to the tangent springs thereby admitting of the wheel being readily
tightened up when required.
The outer rim may be fitted with any approved tyre there being no necessity
for its being fitted with an ordinary pneumatic tyre which this invention is intended
to dispense with.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A wheel for velocipedes and other light vehicles made with two concentric
rims having tangent springs arranged in the annular space between such rims
substantially as and for the purposes specified and as illustrated in the accompanying
drawing.
2. In a wheel for velocipedes and other light vehicles having two concentric
rims (such as A B) the combination therewith of a number of flat steel tangent
springs (such as C C) inserted between said rims, oue end of each of said springs
being secured to the inner and the other to the outer rim whilst the ends of the
spokes are passed through said inner rim and attached each to one of said springs
substantially as aud for the purposes specified and as illustrated in the accompanying
drawings.
