Improvements in Protective Coverings of Rubber Tyred Vehicle
Wheels and in Means for Affixing the same.
I, CHARLES ROSE, of Coolraine House, Limerick, in the County of Limerick,
Veterinary Lieutenant of the Army Veterinary Department, do hereby declare
the nature of this invention (which has been communicated to me from abroad
by William Norman Blount, Sub Agent, Commercial Bank of India Ld., Rawal
Pindi, Punjaub, India,) to be as follows:-
According to this invention I form a protective covering for elastic tyres of
what may be termed chain armour. Preferably this is flexible in one direction
but not in the other. Such armour is formed of transverse helically bent wires.
interlocking with each other. These wires may be all of the same material,
such as steel or iron, but preferably they are of different materials, some being
of phosphor bronze, gun metal or soft steel and the others of hard steel or iron.
To fasten the outer protective covering to the wheel I proceed as follows: Steel
bands are attached at suitable intervals apart, by means of rings, to each edge of
the covering; the covering is put in place over the elastic tyre, and the bands,
which are arranged in pairs, caused to take into a slot in the felloe, and are
clamped together by means of a screw.
The junction of the two ends of the covering may if desirable, be protected by
means of a joint plate.
Between the protective covering and the elastic tyre, a leather pad is inter-
posed in order to prevent destruction of the rubber.
In place of attaching the protective covering to the wheel in the manner above
described, I may, in the case of a solid rubber tyre, attach it by means of bolts
passing centrally through the tyre and felloe, the bolt being made fast by means
of a nut. In order to diminish vibration a helical spring may be interposed,
one end of the spring bearing against the top of a slot in the wheel felloe the
other end bearing against the nut.
Or the covering may be attached to an endless wire, the wire being sprung
round the rim of the wheel or in the case of a pneumatic tyre by causing the
covering to encircle the tyre and the edges to overlap at the rear.

I, CHARLES ROSE, of Coolraine House, Limerick, in the County of Limerick,
Veterinary Lieutenant of the Army Veterinary Department, do hereby declare
the nature of this invention (which has been communicated to me from abroad
by William Norman Blount, Sub Agent, Commercial Bank of India Ld., Rawal
Pindi, Punjaub, India,) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement;-
According to this invention I form a protective covering for elastic tyres of
what may be termed chain armour. Preferably this is flexible in one direction
but not in the other. Such armour is formed of transverse helically bent wires
interlocking with each other. These wires may be all of the same material,
.such as steel or iron, but preferably they are of different materials, some being
of phosphor bronze, gun metal or soft steel, and the others of hard steel or iron.
The junction of the two ends of the covering may, if desirable, be protected
by means of a joint plate.
Between the protective covering and the elastic tyre, a pad of leather, canvas
or other suitable material may be interposed in order to prevent destruction of
the rubber.
Figure 1 is a full sized view of a piece of the armour a and Figures 2 to 7 show
the ways in which I prefer to fix it.
In Figures 2 and 3, steel bands 6 are attached at su ,le intervals apart, by
means of rings c, to each edge of the covering a, the covering is put in place
over the elastic tyre d, leather e being interposed, and the bands 6, which are
arranged in pairs, caused to take into a slot in the felloe f, and are clamped
together by means of a screw bolt g.
In Figure 4 the protective covering a is attached by means of side plates h and
bolts passing through the feline, the bolt being made fast by means of a nut k.
In Figures 5 to 7 the covering is attached to endless wires 7, the wires being
sprung round the rim m of the wheel and the covering may be made to encircle
the tyre and the edges to overlap at the rear as shown in Figure 6.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A protective covering for elastic tyred wheels consisting of chain armour.
2. Protective coverings and the means for affixing the same substantially as
described and illustrated in the drawings.
