I JOSEPH SHAW of Wilson Street Stockport Road, Manchester in the County of
Lancaster Coach Builder do hereby declare the nature of this invention to be as
follows:-
My said invention relates to wheels having recessed or grooved metal tyres which
are fitted with rubber rings or treads for the purpose of obtaining a yielding and
noiseless surface or periphery as is well understood. My invention consists mainly in
the employment of a novel section of metal tyre which holds the rubber more securely
and is more fitted for the purpose than the tyres hitherto in use. The said improved
tyre is of a trough section or flattened C-shape the sides being bent into a curved or
semicircular form so as to over hang and clip the base of the rubber tread which is
forced into the tyre. The base of the said rubber tread is moulded to a shape or
section corresponding to that of the tyre into which it is forced, and a moulded
projection from the said rubber base comes into contact with the ground and takes the
weight of the vehicle. Owing to the curved sectional form of the undercut or
overhanging sides of the metal tyre, water or liquid dirt which may have found
a lodgement within the tyre is not so readily thrown from the wheel during
revolution. The back of the tyre is preferably flattened so as to give a straight
base.

I JOSEPH SHAW of Wilson Street, Stockport Road Manchester in the County of
Lancaster, Coach Builder 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 stateinent and accompanying drawing :-
My said Invention relates to wheels having recessed or grooved metal tyres which
are fitted with rubber rings or treads for the purpose of obtaining a yielding and
noiseless surface or periphery as is well understood. My Invention consists mainly
in the employment of a novel section of metal tyre which holds the rubber more
securely and is more fitted for the purpose than the tyres hitherto in use.
And in order that my said invention may be properly understood I will now
proceed more particularly to describe the same reference being had to the annexed
drawing.
The said drawing is a cross sectional view of the improved tyre a fitted with a
rubber tread band secured to a wheel felloe c. As clearly shown the tyre a is rolled
so as to assume a trough section or flattened “c” shape the sides a¹ being bent into a
curved or semi-circular form so as to overhang and clip the base of the rubber tread b
which is forced into the tyre. The base of the rubber tread is moulded to a
sectional shape corresponding to that of the tyre into which it is forced the outer
projecting portion b₁ of the tread coming in contact with the ground and taking the
weight of the vehicle. Owing to the curved sectional form of the undercut or
overhanging sides a¹ of the metal tyre a water or liquid dirt which may have found a
lodgement within the tyre is not so readily thrown from the wheel during revolution.
As shown in the drawing the back of the tyre u is flattened so as to give a straight
base. An incidental advantage conferred by the projecting curved sides of the tyre
is that the sides of the felloe are prevented from coming into rubbing contact with
surfaces such as the side of curb stones or ruts, thus protecting the sides of the felloe
from damage and disfigurement.
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 :-
The improved section of wheel tyre to receive a rubber tread the said tyre having
curved or semi-circular overhanging sides which clip and secure the base of the rubber
tread substantially as hereinbefore described and shown.
