Improvements in Puncture Proof Bands for Pneumatic Tyres.
I, JOSEPH ROBINSON of 84 Suffolk Road Ipswich in the County of Suffolk
Fitter do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of puncture preventing
bands for pneumatic tyres, and consists in the application of xylonite, flaxoline,
French horn or similar composition in strips, and in the means of applying the same,
I may construct my improved tyre-protector of thin strips of xylonite, flaxoline,
French horn or similar composition, attached to a band of sateen, cotton, linen, silk
or similar fabric, all the strips overlap at the joints. The strips may be attached to
the band or tyre by specially arranged loops of tape, or otherwise attached. This
puncture preventing band is attached to the inside of the outer cover of the
pneumatic tyre.
The thin composition strips are enclosed in loops of tape, fixed in place by sewing
or cementing.
•
The strips are attached to the fabric band by means of the loops of tape thus
allowing free movement of the composition strips. The loops of tape are attached
to fabric band by means of sewing or cement.
The special means of attachment and of overlapping joints secure the flexibility
and resiliency of the tyre, and the protection of the air tube from punctures.

Improvements in Puncture Proof Bands for Pneumatic Tyres.
I, JOSEPH ROBINSON, of 84 Suffolk Road, Ipswich, 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 has for its objects to provide a band that shall efficiently protect
the air tube from puncture and at the same time be flexible and in no wise
detrimental to the resiliency of the tyre nor the speed of the vehicle to which such
puncture-proof tyre is applied.
According to my invention I construct my improved puncture-proof band of
strips or lengths of xylonite, flaxoline, French horn, or similar composition, which
are applied to a band or strip of sateen, cotton, linen, silk or similar fabric, the
strips being arranged longitudinally with respect to the band and overlapping at
the joints. The strips may be attached to the band by specially arranged loops of
tape, in which they may be enclosed, and by which they may be secured in place
by sewing or cementing; or said strips may be secured to the band in any other
appropriate manner.

page_text: In order that my said invention may be readily understood and carried into effect
I will describe the same more fully with reference to the accompanying drawings,
in which:
Figure 1 is a sectional plan of a portion of a puncture proof band constructed
according to my invention and Figure 2 is a transverse section thereof, and
Figures 3 and 4 are similar views of a modified construction.
Figure 5 is a transverse section of a band in which the construction of the fabric
band is slightly modified.
In all the figures like letters refer to similar parts.
Referring more particularly to Figures 1 and 2, a, a, are the strips of xylonite,
enclosed in loops of tape or similar fabric b, which loops are secured by stitching
or cementing to a band or strip of any suitable fabric c'in such a manner that they
overlap one another in the manner shown. If desired I may use a second strip of
fabric to enclose the loops and keep them from becoming turned over or
otherwise accidentally displaced when the band is in use; or the strip c may be
wider than that indicated in the drawing and be folded over to form the cover
strip.c¹.
In the modification illustrated in Figures 3 and 4, I use two rows or layers of
strips of xylonite or the like, the strips of one layer being placed over the edges or
joints of the strips constituting the other layer. In forming this band I prefer to
secure one layer of strips a between two strips of fabric c, b, by sewing or otherwise;
and then to place over this layer a second layer of strips a', which I may secure in
place by cementing them between the strip of fabric 6 and a cover strip c'.
Obviously, instead of using three separate strips b, c and c¹, I may use only one
strip of treble the width, and fold it upon itself twice.
In some cases, however, I may secure both rows or layers of strips in place
by stitching, in which case the bands or strips of fabric are of increased width and
are stitched longitudinally to form the desired number of pockets for the composition
strips, wbich, after their insertion into the pockets, are caused to assume the
superimposed position above referred to by folding one part of the band longitudinally
over the other as represented in Figure 5.
My improved puncture proof band is adapted to be placed or secured inside the
outer cover of the tyre.
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 in a pneumatic tyre is :-
1. A puncture-proof band composed of a number of longitudinally disposed strips
of xylonite or similar material secured in place by means of linen or other fabric
and arranged relatively to each other substantially as described.
2. A puncture proof band or strip constructed substantially as described with
reference to the accompanying drawings and for the purpose specified.
