PROVISIONAL SPECIFICATION.
An Improved Metallic Pneumatic or other Tyre.
I, JAMES HAROLD BARRY of 4 Cadogan Terrace, Victoria Park, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention to
be as follows:-
In pneumatic tyres as at present constructed there is a constant danger of
puncturing to obviate this various means have been devised with little, if any
success, and have had the effect of deadening the tyre or rendering the elasticity,
or resiliency nugatory.
My invention consists in the application and in the mode of applying a material
that whilst being perfectly elastic, is proof against all ordinary puncturing.
I make my tyre preferably of thin magnetic steel which to the best of my
knowledge, and belief has not been used in any form of tyre before, and may be
constructed either as a single tube tyre, and inflated, or with a loose or close fitting
inner tube of rubber or other suitable material, elastic or non-elastic for purposes
of inflating.
When my metallic tyre is to contain an inner tube, I may for convenience of
inserting it, split or cut the metallic tyre longitudinally on its inner circumference
or periphery, and after inserting the inner tube it may be closed on the rim, or the
parts may be joined and cemented, and secured to the rim.
I may secure to the outer periphery of the tyre a sufficient quantity of rubber or
other material to act as a wearing piece or to prevent side slip.
I may make my tyre of preferably a narrow continuous steel ribbon band, which
being spirally wound, the turns overlap each other to the extent required and are
secured by clinching, eyeleting or other suitable means, or I may make the tyre
with two ribbons of this material specially edged and turned so that when pressed
or rolled together the edges will be locked forming an edged or corrugated spiral
tyre, or it may be made in short sections and joined up to form the complete tyre.
I may attach my metallic tyre to the rim in two or more, but preferably two
sections, a space being left between such sections for the entry and fixing of the
inner tube, such spaces being closed in by a small section of tyre. I may secure my
tyre to the rim by attaching in the rim a steel or other band provided with holes
or openings around its circumference, onto which I secure the tyre by means of
hooks, studs, or other means.
I however wish it to be understood that I do not confine myself to any means of
attaching the steel tyre but what I do desire to protect is the application of this
magnetic steel to pneumatic and other tyres and the peculiar constructions, as
described, also all steel or other metal or material tyres constructed as described.

J, JAMES HAROLD BARRY, of No. 4 Cadogan Terrace, Victoria Park, London,
Engineer, 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:-
My invention relates to pneumatic or other tyres and consists in the novel use
and method of application to the wheels of vehicles of a material for forming the
tyre which shall combine the characteristics of perfect elasticity and of nou-liability
to puncture in ordinary use.
I attain these objects by constructing my improved tyre of thin magnetic steel
or other suitable material either as a single tube tyre and inflated, or with a loose
or close-fitting inner tube of rubber or other suitable elastic or non-elastic material
for the purpose of inflating.
And in order that my invention may be more clearly understood reference is had
to the accompanying drawings upon which
Figure 1 is a transverse section of my improved tyre in its simplest form.
Figure 2 being a similar view shewing the metallic tyre enclosing an inner tube.
Figure 3 shews in elevation the method of spirally winding the steel band or
ribbon to form the tyre.
Figure 4 illustrates the mode of construction with two steel bands or ribbons.
Figures 5 and 6 represent alternative forms of edged or corrugated spiral
tyres..
Figure 7 shews the form of the tyre with loose piece for insertion of inner tube.
Figure 8 illustrates the method of attachment to the rim.
In the simplest form of my invention shewn on Figure 1, I make my improved
tyre preferably of a narrow continuous band or ribbon of steel A wound spirally as
shewn on Figure 3, and then secured by clinching, eyeletting or other suitable
means to a metal band B. On the outer periphery or tread of the tyre, I may
attach a band or strip of rubber or other suitable material C of sufficient width
and thickness to serve as a wearing piece, or to prevent side slip in travelling.
Or, I may construct the tyre as shewn in Figure 4 of two ribbons A A¹ of steel
spirally wound in form of a tube and secured to a metal band B as above described,
in such a manner that under any conditions of extension or compression no opening
or interval will be caused between the edges of the convolutions.
Or, I may form my metallic tyre of two narrow bands or ribbons of steel A A'
specially edged and turned so that when placed in position and rolled together
their edges will be interlocked forming an edged or corrugated spiral tyre as shewä
on Figures 5 and 6.
The complete tyre may preferably be constructed, in several sections afterwards
joined together by any suitable method as shewn in Figure 3.
In the application to an inner tube arrangement shewn on Figure 2, I secure a
metal plate D of suitable length upon the inner periphery of the tyre or side facing
towards the rim E of the wheel, and cut a longitudinal slot d through this metal
plate D into the tyre, of sufficient dimensions to permit of the introduction of the
inner tube F into the hollow metallic tyre.
For the purpose of securing my metallic tyre to the rim E, I insert a band G of
steel or other suitable metal in the inner side of the rim E (see Figure 8) and form
-a-series of holes or openings g in the band G to allow of the tyre being secured
thereto by means of hooks, wire loops or other suitable fastenings.

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 pneumatic or other tyres, the construction of a spirally-wound metallic tube
secured to a metal band and having an inner lining of rubber or other suitable
material, substantially as described and shewn on the accompanying drawings,
Figures 2, 3, and 4.
2. In pneumatic or other tyres, the construction of a spirally-wound- metallic
tube as described in Claim 1, divided longitudinally on the inner periphery for the
purposes and substantially as described.
3. In pneumatic and other tyres the mode of attachment to the rim by means of
a loose perforated band substantially as described and illustrated on the accom-
panying drawings.
