PROVISIONAL SPECIFICATION.
Improvements in Rubber Tyres for Wheels.
I, CHARLES SAMUEL STONE of 1 Chester Terrace, Rowan Road Hammersmith
in the county of Middlesex Cab Proprietor do hereby declare the nature of this
invention to be as follows:-
These improvements consist in placing a Rubber Tyre for wheels of Vehicles
inside a metal tyre of such section that the rubber tyre cannot come out or
become loose. The section of my metal tyre is as follows, viz. a hollow or groove,
in or about the middle of which rises from the bottom a continuous V shaped
piece, and the outside part of the groove is sunk inwards so that when the rubber Tyre
which is made to be received by this iron tyre is fitted in it as it were dovetailed
into the iron tyre and cannot possibly come out. A portion of this iron tyre will
be so arranged that the rubber tyre can be slipped in for fixing or repairing the
same.
As my improvements are capable of some modifications without departing from
the principle thereof, I do not restrict myself to materials or dimensions.
Dated this 22nd day of January 1889.

COMPLETE SPECIFICATION.
Improvements in Rubber Tyres for Wheels.
I, CHARLES SAMUEL STONE of 1, Chester Terrace Rowan Road Hammersmith,
in the county of Middlesex, Cab Proprietor, 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 consists in placing a combined rubber tyre and metal tyre upon the
felloe of wheels of vehicles.
The metal tyre which receives the rubber is formed with a hollow groove in section
about the full width of the felloe of the wheel the sides of this metal tyre are turned
inwards and in the centre of the groove is a dovetail shaped piece of metal rivetted to
the tyre.
A continuous piece of rubber oval in section at the outside is formed so as to fit
into this metal tyre.
This rubber portion may be forced in by pressure and also as regards length may be
inserted in sections.
My steel tyre is secured on to the wooden felloe of the wheel by means of pins,.
rivets, or bolts. In order that my invention may be the more fully understood I will
proceed to describe the drawings hereunto annexed and explain the letters of reference
marked thereon. The illustration shows my improvements in section. A is the
rubber tyre which is forced into and securely held by the metal tyre, B which in
its turn is firmly secured to the felloe of the wheel, C is the dovetail shaped metal
piece which is rivetted on to the metal tyre B.
It is to be understood that this section is the same all round the circumference of

page_text: the wheel and that I do not limit myself to the class of rubber 1 may use. I intend
to manufacture the metal tyre of steel.
Having now fully described and ascertained the nature of my said invention, and
in what manner the same is to be performed, I declare that I wish it to be understood
that I am aware that it has heeu proposed to use a rubber tyre retained by a metal
tyre having inwardly bent edges and also that it has been proposed to use a rubber
tyre retained by a dovetail shaped rib and bolts rivets or screws passing through
the said rib and the edges of the tyre and I lay no claim to such arrangement but
what I claim is :—
The combination of a metal tyre having inwardly bent edges and provided centrally 1
with a dovetail shaped rib with a rubber tyre fitting into the metal tyre aforesaid
substantially as and for the purpose described.
