I, JOHN MUNRO of 30 Lidfield Road Stoke Newington in the county of
Middlesex Ironmonger do hereby declare the nature of my invention for
IMPROVEMENTS IN TYRES FOR BICYCLES, TRICYCLES, BATH CHAIRS, AND OTHER
ROAD-VEHICLES to be as follows:-
The object of my invention is to provide a tyre for Bicycles, Tricycles, and other
Vehicles, of light and elastic pattern. For this purpose I use instead of the tyre
of solid rubber a tube of indiarubber or guttapercha with a spiral spring inside.
similar to the tubing used for gas flexible tubing. The wire may be of steel
or soft iron or any metal and the covering may be of any elastic substance such as
is in use for tubes, hose, and the like. The tyre is made in one piece or in halves
or segments and is fastened at the edges with a plug which enters both ends of the
tubing, or the wire of the coil may be brought out so as to pass round and be
fastened on the underside of the iron tyre of the wheel. Cement may also be used.
if preferred.

I, JOHN MUNRO of 30 Lidfield Road, Stoke Newington in the county of
Middlesex Commercial traveller 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 :-
The object of my invention is to provide a tyre for Bicycles, Tricycles, and other
vehicles, of a light and elastic pattern. For this purpose I use instead of the tyre
of solid rubber a tube of india rubber or gutta percha, with a spiral spring inside,
similar to the tubing in general use by gasfitters, and known to them as "gas
flexible tubing." Although this tubing as employed for the purposes of the tyres
may be made of rubber only, with a spiral wire core, yet it may also be strengthened
by using a backing of canvas to prevent the inside tube from any abrasion caused
by the wire spring or core aforesaid. Or the tube may be made in any of the
usual methods, or with any of the materials used in making flexible tubing, as
canvas, leather and such like; although india-rubber is to be preferred. The wire
of the inside core, or coil, or spring is of steel, or soft iron or any metal and in
section, round, oval, square, or flat, as may be found advisable. The tyre may be
made in one piece, shaped by being fixed in a mould, or in halves or segments. To
fasten the same on to the felloe or periphery of the wheel I employ cement.
When the tyre is in segments a plug is prepared from some elastic material as for
instance solid rubber and the ends of this plug are inserted in the ends of the
tubes. This plug may be affixed by rivet, pin, or screw to the felloe of the tyre or
the wire of the coil may be brought out so as to pass round and be fastened on the
underside of the iron tyre, felloe, or periphery 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. A tyre for road vehicles made as a hollow tube of india rubber, or other
substance, with a spring inside as described substantially as set forth.
