do hereby declare the nature of this invention to be as follows:-
The object of our invention is to increase the rigidity and strength of carriage
and other wheels and to diminish their weight and cost. In carrying out our
invention we entirely dispense with wooden felloes and attach the spokes direct to
the metal tyre in the following manner. Along the inner circumference of the
metal tyre we form down the centre a ridge of suitable depth and thickness, the
tyre thus resembling the letter T. At the end of the spokes we form or cut
a longitudinal slot to fit the said ridge so that when the tyre is in position,
the ridge extends up the centre of each spoke; their ends having a bearing
on the inside of the tyre. To connect the tyre to the spokes we then either
drill through the spoke and the ridge of the tyre and insert a screw or bolt,
or by means of a divided socket projecting slightly beyond the spoke we
secure them in position by rivetting the ends of the sockets upon the ridge of
the T tyre, or we may protect the ends of the spokes with metal caps which
fit over the ridge and take a bearing upon the inside of the tyre. In order
to place the tyre in position on the spokes the ends of the tyre are left free and
are afterwards connected by electric-welding or in any manner that may render it
secure and rigid. It will be seen that by dispensing with the wooden felloe and
attaching the spokes direct to the metal tyre, we are able to produce a light strong
and rigid wheel. For wheels having rubber tyres we may form our T tyre of a
channel shape about 4th of an inch in thickness, into which previously we have had
the rubber tyres securely vulcanized and we may then attach the metal tyre to the
spokes of the wheel and secure the ends by means of bolts or rivets, or our rubber
tyre may be slightly flanged upon either side and thickened at the edges thus forming
a concave shape to receive narrow strips of metal which would be rivetted on
either side to the tyre of thin steel already in position upon the spokes.
Another plan of securing our rubber tyre upon the T tyre is to lace it by means
of a double wire cord passing alternately from side to side along and at suitable
intervals through the rubber tyre and also through holes in the steel tyre. Our
T tyres may also be used for wheels known as elastic wheels and built upon the
suspension principle. They may also be used for cycle wheels in which case the
wire spoke may be fitted either into the ridge of the tyre or alternately upon either
side of the upper and flat portion of the tyre. If preferred the outer tyre may
be secured upon these wheels in a similar manner to that hereinbefore described for
carriage wheels.

Wheels.
We, WILLIAM OWEN AVES and EMIL SCHUSTER, 97 Newgate Street, London,
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 our invention is to increase the rigidity and strength of wheels for

page_text: carriages or other vehicles and to diminish their weight and cost. In carrying out
our invention we entirely dispense with. wooden felloes and attach the spokes
direct to the metal tyre as we shall describe referring to the accompanying
drawings.
Fig. 1 is a transverse section of the tyre and part longitudinal section of one of
the spokes fixed thereto.
Fig. 2 is a sectional plan on X X of Fig. 1.
Fig. 3 is a similar section and
Fig. 4 a sectional plan shewing a modification.
The tyre T is a bar of iron or steel of T section which is bent round to circular
form, and, after being connected to the spokes, has its two meeting ends connected,
either by welding them together by electricity, or by connecting them by a fish
plate rivetted on either or on each side of the rib of the tyre. Each spoke. S has a
notch N cut in its end to receive the rib of the tyre and, as shewn in Figs. 1 and 2,
a rivet R holds the parts firmly together. Otherwise, as shewn in Figs. 3 and 4
a metal socket A is fitted on the end of the spoke, this socket having flanges B
which are rivetted to the rib of the tyre.
The socket may have double flanges such as B, one on each side of the rib of.
the tyre which in that case would be embraced between them. In Figs. 1 and 3
the tyre is shewn with a flat tread. It may however be more or less rounded, or it
may be recessed or otherwise shaped to receive an elastic or pneumatic tyre.
cemented or fixed in any known manner upon it.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A wheel for a carriage or other vehicle having its tyre of T section, with the
rib of the tyre fixed in notches in the ends of the spokes, substantially as described,
with reference to Figs. 1 and 2.
2. In combination with the tyre and notched spokes above referred to, sockets
fitted on the ends of the spokes and rivetted to the tyre, substantially as described
with reference to Figs. 3 and 4.
