Improvements in or applicable to Wheel Tyres.
I, CHARLES CHALLINER of 15 Plymouth Avenue, Longsight Manchester, in
the County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
The principal object of this invention is to enable pneumatic balls or segment
tyres, to be applied to the wheels of carriages, for road or other vehicles, and to
enable them to carry heavy loads, without the liability to puncture the tyre, which
is, at present, inevitable.
According to my invention I may construct the wheel with a felloe "much
as usual, and mount thereon a channel, grooved, or of undercut section of Night
metal rim, or the mounted channel, grooved, or of undercut section may be formed
in segments, having side flange or flanges to secure the ball or segment pneumatic
tyres.
The balls or segment pneumatic tyres may be formed in any convenient section,
built up in any number of balls, or segment pneumatic tyres, placed side by side,
until the diameter of the wheel is made up, which will form the complete pneumatic
tyre.
These said balls or segment pneumatic tyres may be manufactured air tight, as
in the case of a tennis ball, they may be each separately inflated, or I may join
the balls or segment pneumatic tyres in the centre, similar to a football, so as to
enable me to insert an air tube, which air tube can be in each ball or segment
pneumatic tyre, independently inflated, or the balls or segment pneumatic tyres
may contain an endless air tube, which, when the said endless air tube is inflated,
will, in combination with the balls or segment pneumatic tyres, form the pneumatic
complete.
Upon the outer periphery of these balls or segment pneumatic tyres, I may cement
by vulcanization or otherwise, an outer surface formed of segments of wood, hard
rubber, or similar suitable material, or without such material, and protect these
balls or segment pneumatic tyres by a hoop-hereafter called the shield-of steel
or other suitable metal or material shrunk, rivetted, bolted, or held on by its own
inflation.
...
:
The balls or segment pneumatic tyres may have projecting feet so as to fit in an
undercut section.
The object of my said shield balls, or segment pneumatic tyres, is to allow the
tyres to take an eccentric position when the weight of the vehicle is applied, or
I may dispense with the wooden felloe and make the felloe of the wheel in any
number of segments of light metal or other suitable material, such felloe will be of
an undercut, or trough-like section having sockets at distances equal to the distance
of the spokes of the wheel, so as to receive the spokes of the wheel, or the section
of the felloe may be formed partly of cast metal or other suitable material, whilst
the upper part of the section may be formed by hoops, rings, or segments, shrunk on,
or otherwise secured; the sides which form the undercut may be made of two or
more rings, hoops, or segments, these may be also shrunk or otherwise secured, and
will form the complete undercut section which will secure the shielded balls or
segment pneumatic tyres firmly in their positions.
This trough or undercut felloe is also applicable to holding any shielded tyres or
any tyres not having a shield. ;
"

page_text: When my said rings, hoops, or segments, which form part of section, are shrunk
or otherwise secured it will secure the wheel firmly together in a way similar to
fixing an ordinary tyre.
My improved shield balls or segment pneumatic tyres are also applicable to
trolley, rail, or other vehicles.

COMPLETE SPECIFICATION.
Improvements in or applicable to Wheel Tyres.
I CHARLES CHALLINER of 15 Plymouth Avenue Longsight Manchester in
the County cf Lancaster, Engineer, 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 principal object of this invention is to enable pneumatic tyres formed of
hollow balls or other shaped segments to be applied to the wheels of carriages, for
road or other vehicles, and to enable the same to carry heavy loads without the
liability to puncture the tyre which is at present inevitable.
The nature of my said invention and the manner in which the same is to be
performed will be readily understood on reference to the sheet of drawings hereunto
annexed and the following explanation thereof.
Fig. 1 on the annexed drawing is a vertical transverse section and Fig. 2 a partial
side elevation of part of the rim and tyre of a wheel constructed according to one
modification of my invention..
According to my invention I may construct the wheel with a felloe much
as usual and mount thereon a light metal rim of a channel, grooved, or undercut
section, or the said metal rim may be made in segments having a fixed or removable
side flange or flanges to secure the hall shaped or other hollow segments forming
the tyre.
In Fige. 1 and 2 a is the light metal rim which may be provided on the inside
with sockets b to fit onto the ordinary wooden, spokes o of the wheel. d are what
I call the balls or segments which may be formed to any convenient section. The
:segments d. (which in the modification shown at Figs. 1 and 2 are in form some-
what like a ball: flattened at one side) may each be manufactured air tight, as in
the case of a tennis ball, and they may be separately inflated each by its own valve,
or they may be joined together in a continuous length (as shown at Figs. 3.aud 4)
being split. beneath and their edges joined together inside the metal rim similar to
a foot ball (see d+ at Fig. 3) so as to enable me to insert therein an endless or
continuous air tube e passing through all the segments, so that the said air. tube e
when inflated will, in combination with the balls or segment tyres d, form a
pneumatic tyre complete.
Upon the outer periphery of these ball or segment pneumatic tyres I may cement
by vulcanization or otherwise, an outer surface or lining formed of segments of
wood, hard rubber, or similar suitable material as shown at Figs. 5 and 54, and
protect the same by a hoop or shield. g of steel or other suitable metal or material
shrunk, rivotted, or bolted thereon; or I may dispense with the lining fand apply
the hoop or shield g directly onto the balls or segments d as shown at Figs. 1, 2, 3, 4.
The balls or segments d instead of having their edges brought together as shown at
Fig. 3.may be made with projecting feet d+ as shown at Fig. 5 so as to fit in the
undercut section of a metal rim, or they may be fastened by loose rings h shrunk op
or otherwise fixed as shown at Fig. 6.
The object in making the pneumatic tyre in the form of a series of separate

page_text: hollow balls or segments is to allow the tyres to take an excentric position with
regard to the felloe when the weight of the vehicle is applied.
When dispensing with the wooden felloe I may make the felloe of any number
of segments of light metal or other suitable material as shown in section at Fig. 7
and side view at Fig. 8 and such felloe will he of a trough-like section as shown at
Figs. 7, 8 and 9 or undercut having sockets 6 at distances apart equal to the
distance of the spokes c of the wheel so as to receive the said spokes. Or the
section a of the felloe may be formed partly of cast metal or other suitable material
whilst the upper part of the section forming the undercut may be formed of hoops
or rings has shown at Figs. 5 and 10 which rings may be shrunk on or otherwise
secured. Or the sides which form the undercut may be made of two or more rings.
or hoops as shown at Fig. 6 and these may also be shrunk or otherwise secured, and
will form the complete undercut section, which will secure the shielded balls or
segment pneumatic tyres d firmly in their position.
This trough-like or undercut felloe is also applicable to holding any shielded or
other pneumatic tyres.
When my said rings, hoops, or segments which form part of the section of the
rim are shrunk or otherwise secured they will secure the wheel firmly together in a
way similar to fixing an ordinary tyre. My improved shield balls or segment
pneumatic tyres are also applicable to trolley, rail, or other vehicles.
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 combination with a light trough shaped metal rim, either undercut or other-
wise, of a pneumatic tyre composed of a series of balls or segments (either inflated
separately or by one continuous air tube) shielded by an outer ring or tyre,
substantially in the manner and for the purposes hereinbefore set forth and illustrated
by the drawings annexed.
