Improvements in or relating to Cycle and other Tyres to Prevent
Puncturing and to obtain other advantages.
We, JOHN THOMSON of 31 Joppa by Porotbello, Electrical Engineer and GEORGE
GIBB, 222 High Street, Portobello, Artist. do hereby declare the nature of this
invention to be as follows:-
This invention is for the effectual prevention of the puncturing of cycle and
other tyres and to obtain other advantages.
This we effect by placing between the inside of the cover and the outside of
the inner air tube a metallic band constructed of highly tempered and polished
steel tape say of an inch wide and say a hundredth part of an inch thick which
tape is interlaced or plaited so as to form a band of the required width to cover
the whole of the puncturable surface of the inner air tube. The steel tape is cut
into lengths say 3 inches long. They are interlaced at an angle of say 45° and
in a ratio of say 5 lengths to every 3 inches in alternate directions. The ends of
the said pieces of steel tape are secured to each other by means of eyelets or the
like. The arrangement being such as to secure the ends whilst allowing the
plaited or braided band to have a certain amount of elasticity longitudinally.
The sharp edges of the tape so constructed, are protected by means of cotton or
other tape solutioned to the steel. In order to effect the punching of the steel for
the purpose of inserting the eyelets, the ends of the pieces of steel are tempered
accordingly. The end of the band may be joined by being overlapped but we may
make the band so that it is endless.
In addition to the effect of the said construction of steel band to prevent
puncturing the said band has also a considerable amount of spring in it when the
band is placed round the air tube and the air tube fully inflated against the said
metallic band, and against the outer cover, which spring increases the buoyancy
of the wheel.

page_text: invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention which relates to improvements in cycle and other tyres consists
in placing, between the inside of the cover and the outside of the inner air tube a
metallic band composed or constructed of short lengths of highly tempered and
polished or nickelled steel tape, which are interlaced or plaited together to form
a band of the required width to cover the whole of the puncturable surface of the
inner air tube, thereby effectually preventing the puncturing of said tyres.
In addition to the effect of the said construction of steel band in preventing the
puncturing of the inner tube it has also a considerable amount of spring when
placed around the fully inflated tube thereby increasing the resiliency and
buoyancy of the wheel.'
But in order that our said invention may be more readily understood and easily
carried into effect, we will proceed to describe the same with reference to the
accompanying drawings in which
Fig. 1 is a view of a portion of a metallic band shewing the face which is pre-
sented to the outer cover
Fig. 2 is an under view of the same portion shewing the face which is presented
to the air tube.
Referring to the said drawings the steel tape, which may be say 3 of an inch
wide and say a hundredth part of an inch thick, is cut into lengths A say 34 inches
long. They are interlaced at an angle of say 45° more or less and in a ratio of
say 5 lengths to every 3 inches in alternate directions. The ends a of the said
pieces of steel tape are pivotted or bound by means of eyelets B, rivets or other
convenient means; the arrangement being such as to secure the ends whilst allow-
ing the plaited or braided band to have a certain amount of elasticity longi-
tudinally. The sharp edges of the steel tape are protected by means of a back-
ing or binding of broad cotton tape C or a band of other material solutioned or
otherwise secured to the steel; the said band overlapping for a distance of say 3 of
an inch on both side of the outer face of the metallic band.
In order to effect the punching of the steel for the purpose of inserting the eye-
lets B, the ends of the pieces are tempered accordingly.
The ends of the band may be joined by being overlapped but we

We desire it to be understood that we do not limit ourselves to the precise
length of strips shewn as it is obvious that they may be varied either way with-
out departing from the scope of our invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The plaited steel band for insertion between the air tube and the outer cover
of cycle and other tyres whereby the tyre is prevented from being punctured and
resiliency obtained, as described and shewn."
2. The arrangement and.construction of the interlaced steel strips A pivotted
or bound together by means of the eyelets or rivets B, and with or without the
cotton or other backing or binding C: substantially as and for the purpose herein-
before described and shewn in the accompanying drawings.-
