PROVISIONAL SPECIFICATION.
Improvements in the Tyres for the Wheels of Cycles, Omnibuses,
Waggons, Railway Carriages, and other Vehicles.
I, WILLIAM HERBERT SEWELL, of Diamond, Coleraine, Ireland, Produce
Merchant, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in the tyres of cycles, omnibuses, waggons,
railway carriages and other vehicles.
The invention consists of a hollow rim or felloe which encloses and so protects a
pneumatic tube or chamber fitted with an inflating or deflating air valve. The
valve projects through wall of rim, which prevents the air tube from creeping or
moving. The wheel is run on a series of sections or segments which are attached
or supported by a flange bearing on inside of the outside or ground face of rim, but
free to work up into or against the pneumatic tube within the rim. These sections
or segments can be easily placed in position whilst the air tube is in a flaccid state
or before it is inflated, but they are irremovably fixed after the inflation of the
tube.
These sections or segments may be designated the shoeing, and may be composed
of various substances, such as metal, indiarubber, gutta percha, wood, whalebone,
or other suitable material, according to the amount of wear or durability desired,
and they may also be in various shapes, such as circles, half-circles, sections of
circles, spheres, or part spheres, flat, square, oval, oblong, or other convenient shape.
They may also be placed round rim so as to form a continuous circle, or spaced or
placed apart so as to reduce ground contact or friction, but at such distances as
will not interfere with the harmony or continuity of motion in running.

Improvements in the Tyres for the Wheels of Cycles, Omnibuses,
Waggons, Railway Carriages, and other Vehicles.
I, WILLIAM HERBERT SEWELL, of Diamond, Coleraine, Ireland, Produce
Merchant, 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 the tyres of cycles, omnibuses, waggons,
railway carriages, and other vehicles.
My invention consists of a hollow rim or felloe which encloses and so protects a
pneumatic tube, or series of chambers fitted with an inflating and deflating air
valve or valves. The wheel is run on a series of sections or segments which are
attached or supported by a flange, bearing on inside of the outside or ground face
of rim, but free to work up into or against the pneumatic tube or chamber within
the rim. These sections or segments are easily placed in position whilst the air
a

page_text: tube or chamber is in a flaccid state or before inflation, but they are irremovably
fixed after the inflation of the tube or chamber.
These sections or segments may be designated the shoeing, and may be either
solid or hollow, and may be composed of various substances, such as metal, iudia-
rubber, gutta-percha, wood, whalebone, or other suitable material or combination of
materials according to the amount of wear or durability desired, and they may also
be in various shapes, such as circles, half-circles, sections of circles, cycloids,
spheres, or part spheres flat, square, oval, oblong, or other convenient shape. They
may also be placed round rim so as to form a continuous circle or spaced or placed
apart so as to reduce ground contact or friction, but at such distances as will not
interfere with the harmony or continuity of revolution of wheel.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings showing my improvements
applied to one form of vehicle on the several figures of which corresponding parts
are marked with similar letters of reference.
Figure 1 is a general view of vehicle showing my improvements applied thereto.
Figure 2 is a part side elevation of rim.
Figure 3 is a transverse section of Figure 2.
A is the hollow rim or felloe of the wheel B, C the pneumatic tube or chamber
and D the valve which projects through the wall of the rim to retain the tube
.in situ.
E are the sections or segments which are provided with flanges F to keep them
in their proper position after the tyre has been inflated.
Although I have shown the pneumatic tube in one continuous piece, it may be in
sections which would facilitate the replacing of a shoe or segment which may have
become damaged or worn. In such case each pneumatic section might be provided
with a separate valve.
In Figure 4 E is the shoe or knob of metal or other material. G is a solid
rubber band with projections to fit the cavity in the shoes or knobs. C is the
pneumatic tube and A the hollow rim or felloe of the wheel.
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 :-
In the tyres of the wheels of cycles, omnibuses, waggons, railway carriages, and
other vehicles constructing these of a hollow rim or felloe in which there is enclosed
either in one continuous piece or in sections a pneumatic tube or chamber provided
with an inflating or deflating air valve or valves and with sections or segments of
any convenient shape provided with suitable flanges which are free to work up into
or against the pneumatic chamber and which are placed round the rim so as to form
either a continuous circle or spaced apart so as to reduce the ground contact or
friction, substantially as and for the purposes herein before described and illustrated
on the accompanying sheet of drawings.
