Certain Improvements in Wheels for Velocipedes, Road Vehicles, and
Skates, and in Tyres for the same, and in their Manufacture.
We, FRANK IORNS GIBBS and WILLIAM WRIGHT trading together as Gibbs
& Wright, of 70, Lower Hurst Street, Birmingham Tin Plate Workers and Metal
Platers, do hereby declare the nature of this invention to be as follows:-
:―
This invention has reference to wheels for bicycles tricycles and other veloci-
pedes and for road vehicles and wheel skates and in tyres for the same, and in
their manufacture.
A wheel tyre constructed according to this invention consists of an inner cork
core strengthened by an internal ring of metal tube or wire or the like, the said
cork core being covered and strengthened by canvas or like material wrapped round
the same, the said canvas being covered and enclosed in an outer covering of
indiarubber which is worked round the canvas covered cork core in the mould in
the process of manufacture. The said cork core by preference made of short
pieces of cork which are cut through in the plane of the ring so as to permit of
the endless tubular or wire or like strengthening ring being inserted between them.
These short pieces of cork are then secured on the said ring by the canvas binding
which is fixed to the cork by suitable cement and then the ring is laid in a mould
(which is also made in halves in the plane of the ring) the said ring thus forming a
permanent core surrounded by the indiarubber which is vulcanized on to the ring.
We thus form a very substantial light tyre which will absorb vibration and last a
long time in wear. When applying our invention to some small wheels. such as
those for skates, each of the halves of the cork ring is or may be made in one piece
instead of being made in several pieces as above described.
The rim of the wheel to which the tyre above described is applied has to be made
in halves in the plane of the wheel, which halves can be separated from each other
so as to permit of the tyre being placed on the grooved rim, the two halves of the
rim being bolted riveted or otherwise fixed together so as to hold the tyre between
them. When the wheel is made with wire spokes we make the two halves of the
rim flanged where they meet together and we widen out the ends of each of the
spokes so as to fit between the flanges and we there secure the spokes by a rivet
passing through each and through the flanges of the two halves of the rim thus
securing the two halves of the rim and the spokes together. Or the ends of the
spokes may be fixed between the flanges by other means.
We sometimes make the tyres above described with an outwardly projecting
annular rib at each side round that part which fits against and in the wheel
rim, and we form the two halves of the wheel rim so as to grip these annular
side ribs of the tyre and thus more effectually secure the tyre in place in the rim of
he wheel.
In order to strengthen the tyre, and particularly when the same is applied
to small wheels, there may be a canvas or other membrane secured to the metallic
ing which is inside the core this membrane extending right through the wheel hub
nd thus increasing the strength of the tyre.

We, FRANK IORNS GIBBS and WILLIAM WRIGHT, trading together as
Gibbs & Wright, of 70, Lower Hurst Street, Birmingham, Tin Plate Workers
and Metal Platers, 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 has reference to wheels for bicycles tricycles and other velocipedes
and for road vehicles and wheel skates and in tyres for the same, and in their
manufacture.
We will describe our invention by referring to the accompanying drawings on

Lube or wire or the like this cork core A being covered and strengthened by

large enough to require it the cork core A is made of short pieces of cork which
are threaded on to the wire ring B, or which are cut through in the plane of the
ring B so as to permit of the endless tubular or wire or like strengthening ring B
being inserted within them. These short pieces of cork marked A, Fig. 2 are then
secured on the ring B by canvas binding wrapped round them and fixed to the
cork by suitable cement thus forming the ring like core which is then covered with
indiarubber D vulcanized thereon as aforesaid. We thus form a very substantial
light tyre which will absorb vibration and last a long time in wear.
When applying our invention to some small wheels such as those for road skates

evident that the tubular or wire ring B is not used. When, however, in these
small wheels the cork core A is required to be strengthened by the tubular or wire
ring B this can be effected by cutting the cork ring through in the plane of the
ring, as shewn in Fig. 7, or by making the said cork ring in halves A1 A2 with the
division in the plane of the ring to admit of the tubular or wire strengthening ring B
being inserted between the two halves A' A' of the cork ring.
The rim of the wheel to which the tyre above described is applied has to be

other to permit of the tyre being placed in the grooved rim, the two halves of the
rim being bolted rivetted or otherwise fixed together so as to hold the tyre between
them. In Fig. 1 the two halves of the rim are marked respectively E' E' and they
are shewn flanged at ee which flanges are bolted together after the tyre has been
placed in position. We wish it to be understood that we make no claim in respect
of making the wheel rim in halves except when used in combination with our
improved tyre herein described.
We sometimes make the tyres above described with an outwardly projecting
annular rib at each side round that part which fits against and in the wheel rim.
The tyres shewn in Fig. 4 and in Figs. 5 and 6 are thus formed, the said pro-
jecting annular ribs being marked respectively F1 F2. The two halves of the wheel
rim are shaped so as to grip these annular side ribs of the tyre and thus more
effectually secure the tyre in place in the wheel rim. In Figure 4 the wheel rim is
shewn as made of two separate hoops E' E' which will slide one within the other
and are made with inwardly turned edges e³ et which clip the annular ribs F F of
the tyre. Screws G secure the two parts E1 E2 of the rim together.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A wheel tyre consisting of a cork core strengthened by one or more wrappings
of canvas cemented or otherwise fixed thereto and an outer indiarubber covering
moulded over and vulcanized to said canvas covered core all substantially as herein-
before described with reference to the accompanying drawings.
2. A wheel tyre consisting of a cork core strengthened by an inner metal
ring and by one or more wrappings of canvas cemented or otherwise fixed to.
said core and an outer indiarubber covering moulded over and vulcanized to said
canvas covered core all substantially as hereinbefore described with reference to the
accompanying drawings.
'
3. Wheel tyres of the kind denoted under Claims 1 and 2 made projecting
annular side ribs F1 F for engaging with the rim of the wheel substantially as
herein before described with reference to Figs. 4, 5 and 6 of the accompanying
drawings.
4. The combination with a wheel tyre of any of the kinds denoted under the
preceding claims, of a metallic trough section wheel rim made in halves adapted
to be divided for placing the tyre on the rim and to be fixed together to grip the
tyre substantially as hereinbefore described with reference to Figs. 1, 3 and 4 of
the accompanying drawings.
