page_text: I, JOHN PITT BAYLY, of 18 Fulhain Place, London, W., in the County of London,
Patent Agent, do hereby declare the nature of this invention (a communication to
me from abroad by Archibald Keir Leitch, of Great Valley, Deltotte, Ceylon) to
be as follows:-
My invention relates to improvements in tyres for cycle and other vehicle
wheels.
In carrying my invention into practice I use a tyre made in the following
manner-
"
The inner tube or portion is made of thin steel, aluminium or other resilient metal
or substance, thus doing away with all danger of puncturing, pumps and the like,
and is made hollow and with the inner portion open with turned in or up sides so as
to allow of yielding, the said opening may be of any suitable width, or the metal
may be spiral in section, or in two halves with turned in and curved sides of any
suitable section, and the outer casing is made of india rubber, cloth, or other
substance so as to minimise jolting or vibration.
Alternately to the employment of a single inner tube, I may employ two or more tubes
of any suitable shape, and therefore I do not limit myself to any particular shape
as the curves may be reversed either inwards or outwards in cross section, or the
inner tube may be in one piece of concentric coiled metal having both sides free.
The rim of wheel is fitted on the tyre instead of the usual way of fitting the tyre
on to the wheel.
The tyre is made the exact size required, and the wheel rim is made either in one
or two or more sections and after being provided with spokes, (or the spokes might
be added after adjustment), is fitted into position and bolted, or otherwise secured.
It should be mentioned that the rim of wheel is made with a groove or hollow so
as to receive the tyre.
What I claim to be new is therefore a tyre made hollow, in one piece, and open on
the inner or rim side, of thin steel, aluminium, or other resilient inetal or substance
of any suitable section (this refers to the inner tube only) covered right round and
throughout with a covering of rubber, cloth or other substance. This tyre may be
made round, elliptical or oval at discretion, and fitting on to the hollow or grooved
rim of wheel, joined by bolts or otherwise at one or at two or more points in the
circumference of the wheel.

page_text: I, JOHN PITT BAYLY, of 18 Fulham Place, London, W., in the County of London,
Patent Agent, do hereby declare the nature of this invention (a communication to
me from abroad by Archibald Keir Leitch, of Great Valley, Ceylon, Deltotte, Planter)
to be particularly described and ascertained in and by the following statement :-
My invention relates to improvements in tyres for cycle and other vehicle
wheels.
And in order that my invention may be thoroughly understood I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon."
Fig. 1, is a transverse section of a tyre with an open metallic tube with turned in
sides.
Fig. 2, is a transverse section of a tyre with a metallic spiral tube.
Fig. 3, is a part of the tyre fixed to the rim of wheel.
Figs. 4, and 5, are tyres with metallic semicircular tubes.
In carrying my invention into practice I use a tyre made in the following manner :-
The inner tube or portion b or d is made of thin steel, aluminium or other
resilient metal or substance, thus doing away with all danger of puncturing, pumps
and the like, and is made hollow and with the inner portion open with turned in or
up sides i so as to allow of yielding, the said opening may be of any suitable width,
or the metal may be spiral c in section as in Fig. 2, or in two halves h with turned
in and curved sides of any suitable section, and the outer casing or cover a is
made of india rubber, cloth, or other substance so as to minimise jolting or
vibration.
Alternately to the employment of a single inner tube, I may employ two or more
tubes h of any suitable shape and therefore I do not limit myself to any particular
shape as the curves may be reversed either inwards or outwards in cross section, or
the inner tube may be in one piece of concentric coiled metal having both sides free.
The rim e of wheel is fitted on to the tyre a instead of the usual way of fitting the
tyre on to the wheel.
The tyre is made the exact size required, and the wheel rim e is made either in
one or two or more sections and after being provided with spokes f and hub
9, (or
the spokes might be added after adjustment,) is fitted into position and bolted, or
otherwise secured.
It should be mentioned that the rim e of wheel is made with a groove or hollow 8
as to receive the tyre a.
The novelty of my invention is therefore a tyre made hollow, in one piece, and
open on the inner or rim side, of thin steel, aluminium, or other resilient metal or
substance of any suitable section (this refers to the inner tube only) covered right
round and throughout with a covering of rubber, cloth, or other substance. This
tyre may be made round, elliptical or oval at discretion, and fitting on to the hollow
or grooved rim of wheel, joined by bolts or otherwise at one or at two or more
points in the circumference of the wheel.
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
1. In tyres for cycle and other vehicle wheels, the combination of a tyre made
hollow in one piece and open on the inner or rim side of thin steel, aluminium,
4

page_text: or other resilient metal or substance of any suitable section covered right round and
throughout with a covering of india rubber, cloth or other substance, substantially
as described for the purpose specified.
2. In tyres for cycle and other vehicle wheels, the combination of an open
metallic tube with turned in sides and the outer india rubber tube or cover
substantially as described.
3. In tyres for cycle and other vehicle wheels, the combination of a metallic spiral
tube and the outer india. rubber tube or cover, substantially as described.
4. In tyres for cycle and other vehicle wheels, the combination of two semicircular
open tubes with turned in edges and the india rubber tube or cover, substantially as
described.
5. In tyres for cycle and other vehicle wheels, the combination of the various
parts fully described in the above specification for the purpose specified.
