Improvements in Tyres for Cycle and other Vehicle Wheels.
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, Deltotte, Ceylon,
Planter,) to be as follows:-
-
My invention relates to improvements in tyres for cycle and other vehicle wheels,
and is intended to be used in conjunction with a Patent granted to me No. 2424,
bearing date January 29th, 1897.
In carrying my invention into practice I use a tyre made in the following
manner:-
The inner tube or tubes are made of thin steel, aluminium or other resilient
metal or substance, and is made hollow and with the inner portion open with turned
in or up sides or edges so as to allow of yielding; the open metallic tube may be
made in one piece, or in two open semicircular tubes with turned in and curved
sides or edges in section, and the outer casing or cover 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. The rim of wheel is fitted on to
the tyre or the tyre may be fitted on to the rim of 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 and hub, (or the
spokes might be added after adjustment,) is fitted into position and bolted, or other-
wise secured.
It should be mentioned that the rim of wheel is made with a groove or hollow
so as to receive the tyre.
The novelty of my invention is therefore a tyre made hollow, in one or more
pieces, and open on the inner or outer side of the rim, 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.
If preferable a canvas cover or lining may be fixed to the inside of the india
rubber cover for additional protection.

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, Deltotte, Ceylon,
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 is intended to be used in conjunction with a Patent granted to me No. 2424,
bearing date January 29th 1897.
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 open metallic semicircular tubes
with turned in edges.
Fig. 2, is a part of a tyre with an open metallic tube with turned in edges
fixed to the rim of a wheel.
In carrying my invention into practice I use a tyre made in the following
manner:-
The inner tube or portion c or semicircular tubes g and h are 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 or edges i so as to allow of yielding, the said
opening may be of any suitable width; the open metallic tube c may be made in
one piece as in Fig. 2, or in two open semicircular tubes 9 and h as in Fig. 1, with
turned in and curved sides or edges i in 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 as in Fig. 2, I may employ
two or more tubes 9 and h of any suitable shape and therefore I do not limit myself
to any particular shape.
The rim 6 of wheel is fitted on to the tyre a or the tyre may be fitted on to the
rim of the wheel.
The tyre is made the exact size required, and the wheel rim 6 is made either in
one or two or more sections (as described and illustrated in my Specification
No. 2424, of 1897) and after being provided with spokes d and hub e (or the spokes
might be added after adjustment,) is fitted into position and bolted, or otherwise
secured.
It should be mentioned that the rim b of wheel is made with a groove or hollow
so as to receive the tyre a.
The novelty of my invention is therefore a tyre made hollow, in one or more
pieces, and open on the inner or outer side of the rim, of thin steel, aluminium,
or other resilient metal or substance of any suitable section but more particularly
in the sections shown on the drawing (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.
If preferable a canvas cover or lining f may be fixed to the inside of the india
rubber cover a for additional protection as in Fig. 1.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, 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 outer or tread side of thin steel, aluminium,
or other resilient metal or substance of any suitable section covered right round
and throughout with a covering of india rubber, canvas, cloth or other substance,
substantially as herein described and according to the accompanying drawing.
2. In tyres for cycle and other vehicle wheels, the combination of an open
metallic tube with turned in sides or edges and the outer india rubber tube or cover,
substantially as described.
3. In tyres for cycle and other vehicle wheels, the combination of two semicircular
open tubes with turned in edges, the canvas and the india rubber tube, or cover,
substantially, as herein described and according to Fig. 1, of the accompanying
drawing.
4. In tyres for cycle and other vehicle wheels, the combination of the various
parts fully described in the above specification for the purpose specified.
Dated this 14th day of January 1898.
