PROVISIONAL SPECIFICATION.
Improvements in or connected with Velocipede and other Wheels.
I, JAMES JOSEPH WARRY, of 42, Melton Road, Birkenhead, in the County of
Chester, Commission Agent, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to the tyres and rims of velocipede and other
wheels, and it has for its object mainly to provide tyres or rims of velocipede and
other wheels which shall not possess the defects or weaknesses of the hollow air
filled tyres commonly in use on velocipedes at present.
According to one construction under this invention the tyre or rim of the wheel
comprises a metallic springy or elastic band or hoop, and rubber arranged as
transverse bars, lying straight across or diagonally, or in zigzag form, across or on
said band or hoop; or as knobs or pieces of irregular formation. These parts or
pieces may, in one arrangement, be connected together by a comparatively thin
rubber portion, or by and on canvas or canvas and rubber, or other suitable means
and materials. Between this metallic band or hoop, and an inner rim or hoop, I
provide an elastic medium such as metallic springs of suitable form; or, in some
cases I employ an annular case of rubber or rubber and canvas or other material
filled with air; or, in lieu of this tube or case I may employ balls of similar
material or materials filled with air; or, in some cases these may be solid.
In case the rims or tyres are enclosed, the outer and inner rims, or either of
them are in the form of channels, the flanges of which overlap.
The outer metallic band or hoop (which may be of steel or other suitable metal
or alloy) may be flat or arched, and when transverse strips or bars of rubber are
used across this band or hoop, they may be flat or curved.
or
A suitable means or a suitable construction is provided by which the outer and
inner bands or hoops are coupled or locked together so as to prevent their having
circular movement about one another.
In some cases, the rubber exterior or rubber and steel may be arranged to fit in
grooves or recesses in the side or edges of the rims.
In some cases the springs may be of coach-spring form, or of wave form, whilst
in others they may be of spiral or volute form; or other suitable arrangement or
construction of springs may be used, and they may be adapted to be used or work
under compression only, or tension only, or under both tension and compression.

COMPLETE SPECIFICATION.
Improvements in or connected with Velocipede and other Wheels.
I, JAMES JOSEPH WARRY, of 42, Melton Road, Birkenhead, in the County of
Chester, Commission Agent, 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 has reference to the tyres and rims of velocipede and other
wheels, and it has for its object mainly to provide tyres or rims of velocipede and
LD

page_text: other wheels which shall not possess the defects or weaknesses of the hollow air
filled tyres commonly in use on velocipedes at present.
The annexed drawings illustrative of this invention, shew in Figure 1 a cross
section through the tyre and wheel rim, and in Figure 2 a cross section of the
outer cover, extended.
Referring to the drawings, a is the rim of the wheel, and is a thin steel or other
suitable metal band or hoop of an elastic or springy nature or construction, having
its edges turned outwards and lying within the inturned edges a' of the rim a.
e is a rubber and canvas or equivalent covering to the ring or hoop b, having at its
edges enlarged or bulbous portions e, which lie between the edges of the hoop b
and the rim edges a'. d is an internal rubber tube or bladder, which is adapted to
be filled with air in the manner of ordinary pneumatic tyres, and forms the support
to the hoop h.
As will be seen by the drawing, a certain amount of space is provided between
the edges and the bottom of the rim a for the movement or play of the edges of
the hoop within the rim, when being used. The enlarged or bulbous portious c¹
of the cover e form cushions between the edges and the rim edges a¹ and prevent
metallic contact between the parts a and b.
By the construction herein described, an absolute obviation of puncturing of the
inner tube d is provided by the hoop b
The hoop may be of steel, alloy, or any suitable metal having the desired
elasticity and resilience and in most cases if made of steel should not be thicker
than th of an inch, ", or even less, being about a suitable strength.
On the outer part or cover of the tyre, ribs or corrugatious or roughenings may
be used in any known manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described improvement in pneumatic tyres, consisting of a tyre
comprising a rim, as a, and a metal hoop as b, the hoop being kept in place by the
rim a substantially as set forth.
2. The pneumatic tyre consisting of the rim a with inwardly turned edges a¹,
the metal hoop with edges b', the internal pneumatic tube or bladder d, and the
cover ; particularly as set forth with reference to and shewn in the drawings.
Dated this 30th day of April 1894.
