Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I EDWARD NUNAN of 166 Fleet Street London Gentleman, do hereby declare
the nature of my said invention for IMPROVEMENTS IN THE TYRES OF WHEELS
FOR VELOCIPEDES AND SIMILAR VEHICLES to be as follows:-
My invention consists in inserting a tube, wire or wires, or band of plain or
Tshaped iron leather or other material in the face of rubber tyres to prevent
compression at the point or place of contact with the road or surface over which
such wheel or wheels run thereby avoiding the impediment caused by such
compression to the easy propulsion of such wheels.

page_text: I EDWARD NUNAN of 166 Fleet Street, London, Gentleman, do hereby declare
the nature of my said invention for "IMPROVEMENTS IN THE TYRES OF WHEELS
FOR VELOCIPEDES AND SIMILAR VEHICLES," and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
My invention consists in inserting a tube, wire or wires or a band or plain or
T shaped iron, leather, or other material in the face of rubber tyres to prevent
compression at the point or place of contact with the road or surface over which
such wheel or wheels travel-thereby avoiding the impediment caused by such
compression to the easy propulsion of such wheels.
The annexed sheet of drawings show several examples of carrying my invention
into practice ench figure being in section through the rubber tyre A. and rim B of
a wheel, C being one of tho spokes.
In Figure 11 show a metal tube D embedded in the rubber A so that it bears
upon the ground and resists compression of the rubber at the point of contact with
the ground while travelling and obtains a better grip. I have shown this tube D
of annular shape but it may be flattened or of other convenient form to present a
wider tread if necessary. In this Figure the metal of the tube D acts in conjunction
with portions of the rubber as the tread as also in the section shown at Figure 2
which represents a solid metal wire D imbedded in the rubber A.
In Figure 3 I show two of such solid wires D but they may be in tubular form
close together and embedded in the rubber A in order to get a wider tread of the
metal than that shown at Figures 1 and 2, but these wires D may be embedded at
a distance apart so as to keep the rubber A between them clear of the ground or
they may be embedded so that the intermediate portion of the rubber acts in
conjunction with the wires for preventing slip of the wheel while travelling.
In Figure 4 I show a slightly hollowed or curved metal band D partly cimbedded
in the rubber A and in Figure 5 a flat or plain metal band D.
At Figure Ga T shaped form of metal band D is shown, the web E being embedded
within the rubber this being moulded to suit. This Ț iron has a rounded face but
in Figure 7 it has a flat face which produces a wider Tread surface.
Figure 8 represents a tyre A with a gutter shaped iron D having the edges
embedded within the rubber the tread projecting beyond the circumference of the
rubber so that the metal alone comes in contact with the ground.
In Figure 9 I show a metal band with angled sides one portion being imbedded
in the rubber the other portion projecting to form the tread.
At Figure 10 I show a wire or it may be a metal tube wholly imbedded within
the rubber near its tread portion.
I have hertofore spoken of metal wires, or bands but other material such as
leather may be substituted for the bands or any other material may be used found
suitable for the purpose.

page_text: The application of a harder cured rubber to or embedded in the tread surface of
an ordinary rubber tyre is within the scope of my invention.
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
The employment of a tube, wire or wires or band of iron, plain or T shaped or
strips or bands of leather or other material embedded in the rubber or tyre of
velocipedes or similar vehicles substantially as shown in the annexed drawings for
preventing compression at the point of contact with the ground as set forth.

Agent for the said Edward Nunan.
