Improvements in Elastic Wheel Tyres.
I, WALTER STABLES SMITH of 6 Hanover Street, in the City of Glasgow,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide a tyre for wheels of cycles and
carriages generally which shall have the advantages of the ordinary pneumatic
tyre as regards resiliency whilst being free from liability to injury by puncture.
The improved tyre is composed of a resilient tube of spirally wound or woven
wire of steel or other substance including wood, or rings of such wire place.I
around the wheel rim and combined with a cushioning of small hollow tubes of
rubber or of spirally wound wire or rings of rubber or other resilient material
placed between the tyre proper and the concave part of the wheel rim. The
tubular tyre may be made of straight, spiral or otherwise shaped wire woun
spirally or in rings round and upon the wheel rim and it may be laid on it loosely
or secured thereto by suitable fastenings. One or more layers of canvas or
rubber fabric may surround the wire tyre or it may be enclosed by a detachable
cover having a rubber or like tread in which case the detachable cover is
preferably formed with tubular edges which when the tyre is placed on the rim
are inflated to serve the two-fold purpose of preventing accidental detachment aud
of acting in whole or in part as the cushioning between the tyre and the
wheel rim.

I, WALTER STABLES SMITH, of 6 Hanover Street, in the City of Glasgow,
Merchant, do hereby declare the nature of this invention and in what manner
the same is to be performed, to he particularly described and ascertained in
and by the following statement :-
This invention has for its object to provide a tyre for wheels of cycles and
carriages generally which shall have the advantages of the ordinary pneumatic
tyre as regards resiliency whilst being free from liability to injury by puncture.
As illustrated under one modification by the accompanying drawings, Fig. 1 of
which is a transverse section and Fig. 2 a longitudinal section, the improved tyre
is composed of a resilient tube A of spirally wound wire as shewn, or woven wire
of steel or other substance, or rings of such wire placed around the wheel rim and
combined with a cushioning of one or more air tubes B of rubber, one only being
shewn on the drawings, or other resilient material placed between the tyre proper
[Price 81

page_text: and the concave part of the wheel rim C. The tubular tyre A may be made of
straight, spiral or otherwise shaped wire wound spirally or in rings round the wheel
rim C and resting on the air tube. As shewn by the drawings a layer D of canvas
or rubber fabric may surround the wire tyre and this is further enclosed by a
detachable or other cover E having a rubber or like tread F, in which case the
cover E is wired on as shewn at G, or it may be secured by a single wire lying in
the centre of the wheel rim or by cementing or in any other well known way.
The tubular tyre A is by preference secured by sewing or otherwise to wires H
which have previously been secured to the outer cover E as shewn, the object
being to prevent the twisting of the tubular tyre A within said cover."
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 :-
A wheel tyre composed of a resilient tube of spirally wound or woven wire
resting on an air tube or tubes placed between it and the wheel rim and retained
in position by means of an outer covering or jacket substantially as described.
