Improvements in Elastic Tyres.
Year: 1897

page_text: We, HENRY CROOK BEVAN, of Blaina, Monmouthshire, Medical Practitioner, and
WILLIAM REES JAMES, of 3 Lancaster Street, Blaina, Monmouthshire, Electrician,
do hereby declare the nature of this invention to be as follows:-
This invention refers to india-rubber or other inflated or cushion tyres for wheels,
and consists in making the said tyre of one or two flat bands having beaded or piped
edges or enlarged selvages which are brought together and gripped by the rim or
which engage with curves or recesses formed in the rim of the wheel to receive them.
The rim may be constructed in two concentric parts of equal diameter one of which
receives the spokes and the other is screwed against the former, both having flanges
which grip the enlarged edges of the tyre band, compressing them together and so
making an air-tight tube of the interior of said band. This interior may be filled
with pulverized cork or other light resilient material, or it may be inflated in the
ordinary way.
In the case of two bands being employed they may have their edges gripped by
the same flanges, or they may each be made to engage with separate flanges or
recesses formed in the rim to receive them.

Improvements in Elastic Tyres.
We, HENRY CROOK BEVAN, of Blaina, Monmouthshire, Medical Practitioner, and
WILLIAM REES JAMES, of 3 Lancaster Street, Blaina, Monmouthshire, Electrician,
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 refers to india-rubber or other inflated or cushion tyres for wheels,
and consists in making the said tyre of one or two flat bands having beaded or piped
edges or enlarged selvages which are brought together and gripped by the rim, or
which engage with curves or recesses formed in the rim of the wheel to receive them.
The rim may be constructed in two concentric parts of equal diameter, one of which
receives the spokes and the other is screwed against the former, both having flanges
which grip the enlarged edges of the tyre band compressing them together and so
making an air-tight tube of the interior of said band. This interior may be filled

page_text: with pulverised cork or other light resilient material, or it may be inflated in the
ordinary way.
In the case of two bands being employed they may have their edges gripped by
the same flanges, or they may each be made to engage with separate flanges or
recesses formed in the rim to receive them.
We will now describe the invention with reference to the accompanying drawings
in which:
Fig. 1 shews a section of a flat band detached and formed with beaded edges
according to our invention.
Fig. 2 shews a section of a pneumatic tyre formed of the single flat band shewn in
Fig. 1.
Fig. 3 shews a section of a tyre composed of two flat bands also with beaded
edges.
Referring to Figs. 1 and 2.
a is a band of rubber or other elastic material provided with thickened or beaded
edges b, b. The latter are brought together so that the band in section approximates
to a circle; and the edges 6 engage concave recesses c in the special form of rim d.
This rim d is made up of two portions dd, the part d' is that to which thh spokes e
are attached and the part d² takes the form in side elevation of a ring, the concentric
inner edge d³ of which, is screw threaded to engage a corresponding thread in the
part d. The edges of the band a being confined between the recesses c of the rim,
can be gripped to the degree of tightness required to obtain an air-tight tube, which
is afterwards inflated as an ordinary tyre or used to contain a pneumatic tube.
Referring to Fig. 3.
The form of tyre herein shewn is made up of two bands a¹ a², their free ends
being confined between recesses formed in the rim as above described. The rim in
this case would by preference be wider as shewn.
The bands or band forming the tyre may be provided with one or more beads, in
the latter case the rim would be slightly modified to allow this. Or the band or bands
may be backed or lined with canvas or similar tough wearing fabric, and if preferred
they may enclose an inner air tube inflatable in any well known way.
The method of fixing the tyres to the rims is sufficiently obvious to require no
lengthy description. The beads being put in place, the removable part of the rim is
screwed into its place and may if preferred be secured in position by lateral screws
or bolts.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, We declare that what
We claim is :
1. A pneumatic or other tyre formed of one or two flat rubber bands with piped or
beaded edges, as herein described and set forth.
2. The combination with the tyre described in Claim 1 of a recessed rim formed in
two concentric parts to engage with said tyre, as herein described and set forth.
