PROVISIONAL SPECIFICATION.
Improvements in Wheels for Carriages.
I WILLIAM ROBERT WALKER of 97 Mount Street, Grosvenor Square in the
City of London Ironmonger do hereby declare the nature of this invention to be as
follows:
Steel segment plates made with a hook and angle, for fixing a special made
endless india rubber tyre of sufficient width to prevent the tyre entering tram
metals. The rubber tyre is made with a rib on each edge, it is then stretched on
an ordinary flat or plain iron shod cab or other wheel. The steel hook of the
segment plates fit over the rib of the rubber tyre then the rib of the tyre is
cramped down and the angle of the segment plates forced into a groove of the
felly of the wheel and then screwed or bolted on each side of the felly.

COMPLETE SPECIFICATION.
Improvements in Wheels for Carriages.
I WILLIAM ROBERT WALKER of 97 Mount Street Grosvenor Square in the
County of London Ironmonger 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 :-
The object of my invention is to provide a ready and effective means for securing
rubber tyres to the wheels of vehicles such as hansom cabs carriages and the like
and also a rubber tyre of peculiarly suitable section for such purpose.
In carrying out my invention I form the rubber tyre of a section having a rib or
flange on cach side or edge such as shown by Figures 1 and 2 on the sheet of
drawings attached hereto and to which with the letters of reference I shall refer in
further describing my invention. The rubber tyre is sprung or stretched over or
on to an ordinary flat or plain shod wheel. Segmental plates of a section shown
by D D Fig. 3 are then cramped down on either side of the felloe until the hooks
or bulbs E E fit closely into the angles FF Fig. 1 of the rubber. The segmental
plates are then secured by screws G at the sides and if desired other screws may
be passed through the whole thickness of the rubber and side plates to assist in
keeping the rubber in position. In making a new wheel the sides of the felloes
may be chased or sunk to receive the side plates so that these may be flush with
the upper or inner portion of the felloes.
Figure 4 is a section of a modification of my invention intended for a new wheel
in which on one side (preferably the outside) of the wheel the retaining plate with
its hook or bulb and the metal tyre are in one piece as H (and these may be either
segmental or continuous) whilst on the opposite side are fixed the hooked segmental
plates such as D before described and shown in Figure 3.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. Forming the rubber tyres for carriages and like vehicles of a shape or section
such as shown by Figures 1 and 2 in the accompanying drawings and substantially
as hereinbefore described or any mere equivalent therefor.
2. For securing flanged rubber tyres to the wheels of carriages the use of

page_text: metallic segmental plates having hooks bulbs or the like at their lower extremities
substantially as described and as shown by D D on the accompanying drawings.
3. For securing flanged rubber tyres to the wheels of carriages the use of a
combined metal tyre and side plate such as H substantially as hereinbefore
described and as illustrated by Figure 4 in accompanying drawings.
4. In wheels for carriages the combination of a flanged rubber tyre with metallic
segmental hooked or angle plates for securing the same to or over ordinary or
special metallic tyres substantially as hereinbefore described.
