do hereby declare the nature of this invention to be as follows:-
In accordance with my invention we employ an outer tyre which we prefer to
term, the gripping tyre, which is of Z shape in cross section and in two halves the
several segments of this gripping tyre are not shut together, but the upwardly
projecting sides of same form gripping pieces with a circumferential channel the
base of which is encircled by a "shut "that is to say a solid-steel tyre, and
superposed upon which is the outer or running tyre which is. formed of rubber or
like resilient material gripped and held securely within the walls of the Z split
tyre above referred to.

COMPLETE SPECIFICATION.
Improvements relating to the Wheels of Road Vehicles.
We, GEORGE WILLIAM SMITH, of 7 Wedmore Street, Upper Holloway, N.,
JOHN EDWARD WALKER, 5 Canal Road, Kings Cross, N., and JAMES ROBERT
SLADE HAYES, 7 William Street, Maygood Street, Barnsbury N., Engineers,
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:
Our invention relates to improvements in the wheels of road vehicles and refers
particularly to such wheels as have running tyres of rubber or other resilient
material. The said invention consists in constructing the outer tyre, which we
prefer to term the gripping tyre somewhat of a shape in cross section and which
we make in two halves and in segments. These several segments are not shut
together, but the upwardly projecting sides of same form gripping pieces with a
circumferential channel the base of which is encircled by a "shut "-that is to say
a solid steel tyre, and superposed upon which is the outer or running tyre of
india rubber or other like resilient material gripped and held securely within the
walls of the split tyre above referred to.
And in order that this our invention may be fully understood and readily carried
into effect we have hereunto appended a sheet of drawings illustrative of the same,
in which a and b are the two halves of a segment of the gripping tyre, preferably
not "shut," and held upon the felloes c of the wheel by the "shut"
encircling band of steel d. In the channel formed by the upwardly projecting
sides a 6 of the gripping tyre a b is placed the rubber running tyre.
or solid
To more securely grip and hold the rubber tyre in position we prefer to form the
inner sides of the walls a' b' slightly tapering as shewn and further to make an
inwardly projecting flange or rim ab around the outer edge of said gripping tyre.
The downward projections are tapered on the outside as shewn and marked a³ b³,
and serve to form a wedge when inserted in the wood felloe.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements relating to the wheels of road vehicles substantially as
and for the purposes hereinbefore set forth and shewn in the accompanying
drawings.
2. In the wheels of road vehicles the gripping tyre (preferably not "shut")
formed in segments of double angle or 4 section, for the purpose of securely
holding the running tyre of rubber or other resilient material; and having the
inner branches formed taper so as to act as a wedge when inserted in the felloes,
substantially as herein described and shewn in the drawing.
