PROVISIONAL SPECIFICATION.
Improvements in or relating to Resilient Tyres for Wheels of Road
Vehicles.
I, HENRY CHARLES CRANE, of 15, Collingwood Street, Blackfriars Road, County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for object, a novel construction or arrangement of parts
constituting what are known as shielded rubber tyres for road vehicles, motor
cars, and the like to prevent the rubber pad or cushion becoming injured or
unduly crushed.
For the purpose of this invention, I form the rim cheeks with rounded or
equivalent shaped projecting edges, in the inner faces of which, hollow channels
exist for the reception of key pins for locking the shield sections in place, these
being provided with outwardly projecting lips to bear against the key pins to
prevent the shields falling out, the lips being thus kept within the rim cheeks.
The key pins of, say, steel wire of D shape have their flat surfaces in contact
with the cheeks of the shields for the free in and out motion of the shields due
to the resiliency of the rubber liner or pad which is between the rim and the
shields.
The rim checks may if desired be flat on the outside in which case the hollows
or channels for the key pins would be between the top inner overlap, or inwardly
formed ribs and of lips produced in the rolling operation, and under which the
rubber liner is retained.
The shields may also have inwardly projecting lips at their lower ends for the
retention of the rubber liner when crowded therein.
It will be understood that by my invention, the key pins are in contact with
metal surfaces and are driven into channels of the rim cheeks and bear against
the cheeks of the shields for the shields free play to rise and fall, and these are
held to the rim by the outwardly formed shield lips.
The rubber liner or resilient pad may be of the usual construction or be moulded
with holes for wire or other binding.

Improvements in or relating to Resilient Tyres for Wheels of Road
Vehicles.
I, HENRY CHARLES CRANE, of 15, Collingwood Street, Blackfriars Road, County
of London, 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:-
This invention has for object, a novel construction or arrangement of parts
constituting what are known as shielded rubber tyres for read vehicles, motor

page_text: cars, and the like to prevent the rubber pad or cushion becoming injured or
unduly crushed.
This invention consists of channelling the inner sides of a wheel's rim walls
or side cheeks either by bulging the outside to form also a kerb resisting rib, or
to channelling the inner faces of inwardly projecting rim ribs for the reception
of keys, one face of each of which is flat to be in contact with the plain side
cheeks of a shielded sectional tyre, the walls or cheeks of which are also ribbed
for the keys to act against and so prevent the sectional pieces leaving the wheel
while in use, the resiliency of the tyre sections being dependent upon a rubber liner
or pad which is enclosed between said rim and sections of tyre.
Figure 1 of the annexed drawings, cross section and part perspective elevation
of a wheel tyre for ordinary cabs and light vehicles.
Figure 2, similar view of a wheel for heavy vehicles such as motor cars and
goods delivery vans.
Figure 3 elevation of wheel with part rim wall removed.
I form the checks A. of the rim B with rounded or equivalent shaped projecting
portions C, in the inner faces of which hollow channels exist for the reception
of key pins D for locking the shield sections E in place, these at the cheeks 1', F,
being provided with outwardly projecting lips G, G, to bear against the key
pins D, D, to prevent the shields E, E, falling out, the lips G, G, are thus kept
within the rim cheeks A, A.
The key pins of, say, steel wire, have one flat surface in contact with the
cheeks F, F, of the shield E, E, for the free in and out motion of the shields E, E,
due to the resiliency of the rubber liner or pad H which is between and enclosed
within the rim B and the shields E and the cheeks A, F.
The rim cheeks A may if desired be flat, as at Figure 2, on the outside, in which
case the hollows or channels for the key pins D are between the top inner over-
lap or inwardly formed ribs I, I, and of lips produced in the rolling operation.
The shields E, E, may also have inwardly projecting lips J, J, Figure 2, at
their lower ends for the retention of the rubber liner H when crowded therein.
It will be understood that by my invention, the key pins D, D, are in contact
with metal surfaces and are driven into channels of the rim cheeks A, A, and
bear against the cheeks F, F, of the shields E, E, for the shields free play to
rise and fall, and these are held to the rim by the outwardly formed shield lips G, G.
The rubber liner or resilient pad I may be of the usual construction, or be
moulded with holes for wire or other binding.
h, is the felloe of a wheel to which the rim B is affixed in any desired manner.
L, is one of the spokes of a wheel.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A resilient wheel tyre consisting of outwardly ribbed and inwardly chan-
nelled side walled rims, keys located in said channels and in contact with side
walls of segmental shields held thereto by outwardly projecting lips rubber liner
enclosed within rim and segments shields conjointly as specified.
2. A resilient wheel tyre consisting of a rim having inwardly ribbed and
inwardly channelled side walls or cheeks, keys in said channels, inwardly and
outwardly projecting lips of side walls or cheeks of shield segments, as specified.
