New or Improved Shield or Protector for Tyres of Wheeled Vehicles,
especially applicable to Pneumatic Tyres.
We, CHARLES CRUTE, of 14, Knightrider Street, in the City of London,
Warehouseman, and OCTAVIAN JOHN ALFRED HARRISON, of 76, Holland Road,
Kensington, in the County of London, Engineer, do hereby declare the nature of this
invention to be as follows:-
The object of our said invention is to provide an effective outer metallic shield or
protector for the tyres of wheeled vehicles, especially such tyres as are manufactured
of rubber or other non-metallic material, and more particularly for use in preventing
puncture in pneumatic tyres or the like. Our shield is also intended to prevent side
slipping as far as possible, and likewise to reduce weight if desired, as, by its use, a
thinner inner or outer tube (or both) may be introduced in place of the kind now
generally in use; or it would allow of a single inflated tube protected by our shield,
provided that the same can be satisfactorily attached to and detached from the rim
of the wheel. We may also so attach our shield or protector to the rim that it will
securely keep a single inflated tube, or other type of tyre in position.
In carrying out our invention, we form by rolling and stamping, or otherwise, a
thin metallic segmental shield or protector, preferably of steel, transversely curved to
fit tlie outer diameter of the tyre and of such length as to continue throughout the
whole of the circumference thereof, allowing, if necessary, for lap for a joint. It will
thus form an endless protecting band. At a suitable distance from the centre of this
band, or from the point of impact, we form at each side two or more projections or
corrugations, continuing throughout the entire length of the shield, for the purpose
of preventing side slip. In order to attach, and firmly secure said shield, we form at
intervala, on the edges thereof, and preferably opposite to one another, straps, bands,
or tongues of sufficient length to pass round the outer side surface of the tyre and
through holes, formed for the purpose, in the rim, which in all other respects may be
of any ordinary type. The ends of the tongues, after passing through the holes in
the rim, are turned outwardly and downwardly, thus securing the shield firmly in
position, or any other convenient device may be employed for attaining the same
object.
We may, if desired, form the shield in sections, the end of one section sliding
within, or lapping over the end of the next adjacent, the joints preferably being at
the points at which the tongues or clips occur, so as to allow for contraction and
expansion or for slight alteration of the length of shield; and for this purpose,
the joint of a shield in one length need not be a rigid one.
It will be seen that our invention may be applied to tyres or motor carriages or
vehicles other than cycles:

New or Improved Shield or Protector for Tyres of Wheeled Vehicles,
especially applicable to Pneumatic Tyres.
We, CHARLES CRUTE of 14, Knightrider Street, in the City of London,
Warehouseman, and OCTAVIAN JOHN ALFRED HARRISON of. 76, Holland Road,
Kensington in the County of London, Engineer, do hereby declare the nature of this
invention and in what manner the saine is to be performed, to be particularly described
and ascertained in and by the following statement ;-
The object of our invention is to provide an effective outer shield or protector for
the tyres of wheels when such tyres are manufactured of rubber or other non-metallic
material and more particularly for tyres of the pneumatic or cushion type for preventing
puncture of the saine. Our shield is also intended to prevent side slip as far as
possible, and it may also be utilised for reducing the weight of rubber tyres, as by its
employment a thinner inner or outer tube or both may be introduced in some cases
in place of those in ordinary use, or it might allow of a single inflated tube or a
"tubeless tyre "being used, provided that such can be satisfactorily attached to and
detached from the rim, and we may so attach or secure our shield to the rim that it
will alone keep a tube or other like tyre in position.
In the following description of our invention and of the mode of carrying it into
effect, we shall refer to the accompanying sheet of drawings and the Figures and
letters thereon.
Figure 1 being a view of a portion of a wheel and tyre fitted with our shield which
in this case is shown as a continuous one.
Figure 2 is a section of the rim, tyre and shield through 2------2 which is one
of the points at which the shield is secured to the rim.
Figure 3 is a similar section through 3------3 lying between the securing points.
Figure 4 is an enlarged view of the rim and shield at a securing point.
Figure 5 is a view of an overlapping sliding joint suitable for use with our shield.
In carrying out our invention according to Figures 1 to 5, we form by rolling or
stamping or both (or otherwise) a thin metallic segmental shield or protector. A
preferably of steel, and transversely curved as shown in Figure 3 to fit the outer
diameter of a tyre and of such a length as to continue throughout the whole of the
circumference thereof, allowing when necessary for lap, for a sliding joint, Figure 5,
or a rigid joint if preferred, or the shield may be formed in lengths or sections with
several of such joints or laps, allowing the ende, or one of them to slide when under
pressure, so providing for contraction or expansion at any point of the circumference.
The shield when fixed thus, forins an endless protecting band or cover for the tread
of the tyre. At a suitable distance froin the centre or point of impact, we may form
on each side one or more projections or corrugations B B, continuing throughout the
entire length of the shield, or arranged in "bit and miss" fashion, for the purpose of
preventing side slip. In order to attach and firmly secure the shield A to the rim C,
we form at intervals on the outer edges, and preferably opposite to each other, straps,
bands. or tongues D D, (see Figures 1, 2, and 4) integral with or attached to the
shield and of sufficient length to pass round the outside surface of the tyre and
through holes or slits E E, fórmed for the purpose in the rim C, which said rim may
be in all other respects of any usual type to suit the tyre in use.
The ends of the tongues D D may be bent, curled or turned outwardly and
downwardly as at FF, so as to become, after being passed through the holes E E,
clips or fasteners, kept in position by inflation of tyre or pressure thereof, or, if
preferred, the shield may be held on by straps of any convenient kind. The shield
may also in some cases, be further secured by gutta-percha or other adhesive substance.
We may, as before suggested, form the shield in lengths or sections with sliding or

page_text: other joints at intervals, one instance of which is shown in Figure 5, the end of one
section such as H sliding within or lapping over the adjacent end I, which for
convenience of securing would be situated at a point at which one of the securing
straps or tongues D occurred, and such end H could be widened out and formed as
shown, having a return clip K or like device to engage over lower part of tongue D..
It will be seen that our invention may be applied with advantage to tyres of
Motor care as well as Cycles and also to other types of carriages where non-metallic
tyres are used.
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. For protecting rubber, pneumatic, or other non-metallic tyres of wheeled
vehicles, a continuous ahield or protector secured or held close upon the outside edge
or "tread" of the tyre by means of straps, bands, or tongues substantially as
described in the foregoing specification with reference to the accompanying drawings.
2. For protecting rubber, pneumatic, or other non-metallic tyres of wheeled
vehicles a shield or protector A surrounding the outer diameter or tread of the tyre
to which it is secured or held close by means of straps, bands, or tongues and having
non-slipping ridges B substantially as described.
3. For protecting rubber, pneumatio or other non-metallic tyres of wheeled
vehicles a shield or protector A furnished with one, two, three or more overlapping
joints substantially as described with reference to Figure 5 of the accompanying
drawings.
