Improvements in or relating to Pneumatic Tyres for the Wheels of
· Cycles, Motor Cars, and other Suitable Vehicles.
I, CLEMENT ARTHUR HILL, of Humber Chambers, Princes Dock Street, Hull, in
the County of Yorkshire, Coal and Iron Merchant, do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to provide an improved tyre for cycles or the
like, such tyre being on the pneumatic principle and consisting of independent
bodies of the shape or form hereinafter described, by means of which the punctur-
ing of one or even several of the bodies does not cause the deflation of the whole
tyre, which can still be ridden without noticeable inconvenience; also the tyre if
punctured may be easily repaired by the insertion of new or duplicate parts.
For the purpose of my invention, I construct my improved tyre of a suitable
number of small air chambers in the form, preferably, of hollow rings, but if
desired hollow balls may be employed, disposed longitudinally each on its own axis
around the rim of the wheel, close or nearly close together, and attached separ-
ately to the sides of the wheel rim by means of pins and nuts and internal screws
or the like, the rim being provided with receiving holes, slots, or projections,
for taking the said pins or the like, which form an axis or shaft through or
near to the centre of the aforesaid hollow rings or balls; but there are various
other ways of attaching the rings or balls to the wheel rims which cannot be
detailed in a Provisional Specification.
When balls are employed, they are preferably flattened at each side somewhat
like an orange, and when secured in position are further nipped or closed in,
giving them when in position, a similar outline to the hollow rings before
mentioned.
The wheel rims are preferably of a special shape to receive the resilient rings
or balls, but the invention may be applied to any suitable rim.
A device for tightening the air chambers of the inflated bedies in the event
of any slight deflation or sinking may be attached to or form part of the device
for connecting the rings or balls to the wheel rim.
It will be seen from the foregoing description, that each ring forms a complete
circular chamber around the pin or other device which secures it in position, and
that each ball forms a hollow air space extending to the circumference of its
inner periphery around its connecting or attaching. device, this gives the balls
or rings, whichever are used, the appearance of small wheels, the outer segment
of the circle showing beyond the rim, and acting as the tread, the inner segment
being enclosed by the rim.
The rings or balls are preferably made in one piece, of rubber or other suitable
resilient material or substance, and may be suitably strengthened at the inner

page_text: circle of their axes if required, and they may have the position of the axis or
point of connection of the centre pins or other devices placed out of the centre of
the ring or ball, so that the exterior tubular or circular segment forming the
tread would have a larger or deeper air space than the segment enclosed by the
rim, thereby allowing of the rim being made smaller or shallower than it other-
wise could be.
The air chambers may if found desirable be provided with small holes or slots
for the free ingress and egress of the air, these may be formed by the pins or
other connecting devices
The rings or balls may be provided with projections to take the wear caused by
coming in contact with the ground.
The said rings or balls may be inflated by means of a valve in combination
with the connecting devices.
In this invention the use of an outer covering to the tyre may be dispensed
with, but nevertheless I may make use of a suitable auxiliary cover affixed in
any convenient manner, if desired.

Cycles, Motor Cars, and other Suitable Vehicles.
I, CLEMENT ARTHUR HILL, of Humber Chambers, Princes Dock Street, Hull, in
the County of Yorkshire, Coal and Iron Merchant, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
---
The object of this invention is to provide an improved tyre for cycles
or the
like, such tyre being on the pneumatic principle and consisting of independent
bodies of the shape or form hereinafter described by means of which the punctur-
ing of one or even several of the bodies does not cause the deflation of the whole
tyre which can still be ridden without noticeable inconvenience, also the tyre if
punctured may be easily repaired by the insertion of new or duplicate parts."

rim and with supports or axles formed of double flanged screws having nuts for
the purpose of nipping the body up tightly within the rim.
For the purpose of my invention I construct my improved tyre of a suitable
number of small air chambers A in the form preferably of hollow rings each
having a hole A¹ through it, but if desired hollow bodies of a somewhat ellip-
tical shape may be employed, disposed longitudinally each on its own axis
around the rim B of the wheel, close or nearly close together and attached sepa-
rately to the sides of the wheel rim B by means of pins or tubular axles C
and nuts D and internal screws or the like, the rim being provided with receiv-
ing holes, slots or projections for taking the said pins or the like which form an
axis or shaft through or near to the centre or hole of the aforesaid hollow rings
or elliptical shaped bodies A, but there are various other ways of attaching the
tyre sections to the wheel rims which cannot be detailed but which would not
avoid the scope of my invention.
The hollow elliptical shaped bodies referred to above may be secured in position
by means of preferably double flanged threaded tubes E the flanged tubes passing
through the holes in the walls of the bodies which fit between the flanges, and
being secured by nuts C¹ outside the rim, giving the sections when in position
a similar outline to the hollow rings beforementioned.
If desired instead of the nut short screws may be employed which pass through
the rim B and into the flanged tubes E which may be threaded internally to take
them.
A device for tightening the air chambers of the inflated bodies in the event
of any slight deflation or sinking may be attached to or form part of the device
for connecting the rings or said bodies to the wheel rim, this may consist of the
employment of loose taper collars F on the tubular axles C, these collars fit within
the central holes of the sections.
It will be seen from the foregoing description that each ring forms a complete
circular chamber around its tubular axle or other device which secures it in posi-
tion and that each elliptical body forms a hollow air space extending to the cir-
cumference of its inner periphery around its connecting or attaching device this
gives such elliptical bodies or rings, whichever are used, the appearance of small
wheels, the outer segment of the circle showing beyond the rim and acting as
the tread, the inner segment being enclosed by the rim.
The rings or bodies are made of rubber or other suitable resilient material or
substance and they may have the position of the axis or point of connection of the
centre pins or other devices placed out of the centre of the ring or elliptical body
so that the exterior tubular or circular segment forming the tread would have a
greater air space than the segment enclosed by the rim, thereby allowing of the
rim being made smaller than it otherwise could be.
The air sections used to build up my improved tyre are filled with compressed
air either during or after manufacture and suitably sealed, such bodies are cap-
able of reinflation from time to time by suitable instruments and may each be
provided with an inflating nipple suitably situated either in combination with the
attaching devices or otherwise.
The rings or elliptical bodies may be provided with projections to take the
wear caused by coming in contact with the ground.
In this invention the use of an outer covering to the tyre may be dispensed

page_text: with but nevertheless I may make use of a suitable auxiliary cover affixed in any
convenient manner if desired.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is
1. A pneumatic tyre consisting of a series of independent detachable pneu-
matic resilient rings, or ring shaped bodies, with central or eccentrically situated
holes, and inflated in any suitable manner, in the manner and for the purposes,
substantially as shown and described.
2. A pneumatic tyre, consisting of a series of independent pneumatic resilient
rings, in combination with means of support allowing their individual attachment
or removal, in the manner and for the purposes, substantially as shown and
described.
3. In combination with the rim of a wheel, a pneumatic tyre arranged therein,
and consisting of a series of independent resilient pneumatic rings, having a part
or parts of their peripheries in contact with each other, the means for fastening
the said rings, and allowing their individual removal, in the manner and for the
purposes, substantially as shown and described.
4. In combination with the trough shaped rim B of the wheel having openings
in its side walls, a series of rods, tubes, or pins passing transversely through the
said openings, rim, and through the rings, means for detachably securing the
said rods in this position, consisting of a screw turned into the screw tapped end
of each rod, and with or without loose taper collars such as F, a series of annular
resilient pneumatic tyre sections, mounted individually on the said rods within
the said trough shaped rim, and having no connection with each other, in the
manner and for the purposes, substantially as shown and described.
5. In combination with the trough shaped wheel rim B, a pneumatic tyre, con-
sisting of a series of rubber or other resilient annular sections E, arranged within
the said rim and in contact with each other, so as to form a continuous series of
sections having no connection between their independent or respective interiors,
in the manner and for the purposes, substantially as shown and described.
6. In combination with the trough shaped rim, of a wheel, a series of hollow
resilient elliptically shaped bodies, having openings in their side walls, and pro-
vided with flanged tubes and screws or other suitable devices for screwing them
to the wheel rim in the manner and for the purposes, substantially as shown and
described.
