PROVISIONAL SPECIFICATION.
Improvements in Protectors for Pneumatic Tyres.
I, SYDNEY LEE, of 9, Furnival Street, in the City of London, Auctioneer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to protectors for pneumatic tyres in which plates of thin
flexible unpuncturable material are laid cross-wise upon the tread of the tyre their
edges over-lapping so as to prevent the cutting of the tyre. Hitherto in protective
bands of this description the plates have been laid upon a band or web of canvas
to which they have been fastened by rivetting, stitching, solutioning or similar
means, the objection to which is that there is not sufficient freedom allowed to the
plates which in consequence are apt to break and damage the tyre.
In carrying out my invention I take a strip of canvas or other suitable material
of the necessary width and fold it in such a manner as to provide a fold or pocket
for each plate the edge of each succeeding pocket lying sufficiently far over the
preceding one to cause the plates to overlap to the necessary extent. I prefer to
have the width of the strip greater than the length of the plates and to secure the
walls of each pocket together beyond the ends of the plates so as to prevent the
latter from working out. By this arrangement a protective band is produced
with overlapping plates but each plate is carried in a separate pocket hinged as it
were to the band so that when the band is taken out of the tyre the pockets
containing the plates can be turned over to either side as though hinged to the
band and thus each plate can readily adapt itself to the movement or shape of the
tyre as required.

COMPLETE SPECIFICATION.
Improvements in Protectors for Pneumatic Tyres.
I, SYDNEY LEE of 9 Furnival Street, in the City of London, Auctioneer, 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:-
This invention relates to protectors for pneumatic tyres in which plates of thin
flexible unpuncturable material are laid upon the tread of the tyre their edges
over-lapping so as to prevent the cutting of the tyre. Hitherto in protective
bands of this description the plates have been laid upon a band or web of canvas
to which they have been fastened by rivetting, stitching, solutioning or similar
means, the objection to which is that there is not sufficient freedom allowed to the
plates which in consequence are apt to break and damage the tyre.
In carrying out my invention I take a strip of canvas or other suitable material,
of the necessary width and fold it in such a manner as to provide a fold or pocket
for each plate the edge of each succeeding pocket lying sufficiently far over the

have the width of the strip greater than the length of the plates aud to secure the
walls of each pocket together beyond the ends of the plates so as to prevent the
latter from working out. By this arrangement a protective band is produced with
overlapping plates but each plate is carried in a separate pocket hinged as it were
to the band so that when the band is taken out of the tyre the pockets containing
the plates can be turned over to either side as though hinged to the band and
thus each plate can readily adapt itself to the movement or shape of the tyre as
required.
In the accompanying drawings:
Figure 1 is a perspective view of a portion of a band complete, and
Figure 2 a similar view of the same band but with the pockets turned the
other way.
Figures 3, 34 and 3B illustrate a modification.
In Figures 1 and 2 A represents a strip of canvas, tape, or other suitable
material folded at B, the two sides returning to the plane of the strip at ab forming
as it were a binge joint, the double fold forming a pocket in which is located the
unpuncturable plate C, Figure 1, where a portion of the canvas is broken away to
show the plate, the rest of which appears in dotted lines. These plates C may be
made of any suitable thin, flexible, unpuncturable material, but preferably they
are thin steel or other metallic plates. It will be seen that the complete pocket D
can be folded over in either direction that is to say it can be laid down flat upon
the strip A until its end B overlaps the next pocket D as shown by the subsequent
pockets which are lying down to the right of the drawing; or, it can be folded to
the left as indicated in Figure 2. The edges or margin D' of the pocket beyond
the plate may be solutioned or otherwise secured together so as to complete the
pocket.
The above described band may be made of a single strip of material, but where
it is desired to employ two strips the result may be obtained by folding one of
them as indicated in Figure 3", placing the plates into the folds thus formed and
covering them with a straight strip. This arrangement is indicated in Figures 3, 3ª 3B
where A in Figure 3B is the folded strip, C in Figure 34 are the unpuncturable
plates overlapping at their edges as shown, and A¹ Figure 3 is the plain cover
strip. In making up this band the unpuncturable plates would be placed in the
folds of the strip A and the plain strip A¹ placed on top of them and the two
strips solutioned together, thus forming the pockets each of which contains its
unpuncturable plate. This would be the same as in the first form but with the
pockets partly solutioned down to prevent excessive movement.
In my Provisional Specification I described the placing of the unpuncturable
plates cross-wise upon the tread of the tyre the length of the plate lying across
the band. This arrangement I can still adopt, but experience has shown that a
more satisfactory result can be obtained by narrowing the plates across the band
and lengthening them in the direction of the length of the band as greater
resiliency may be obtained by that arrrangement. This however is purely a
question of the dimensions of each plate and I merely draw attention to it so as to
set forth the best method known to me at the present time of making the bands.
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. In a puncture-proof band a band composed of a single strip of canvas or
other material constructed and arranged substantially as described and illustrated
in Figures 1 and 2 of the accompanying drawings.
2. In a puncture-proof band a hinged pocket such as D formed by a fold in the
strip or baud A and capable of being folded down in either direction substantially
as described and illustrated in Figures 1 and 2 of the accompanying drawings.

page_text: 3. A puncture-proof band composed of a strip of canvas or other suitable
material such as A unpuncturable plates C and a plain strip of fabric such as A¹
the whole constructed and arranged substantially as described and illustrated in
Figures 3 34 and 3 of the accompanying drawings.
