Certain Improvements in Tyres and Wheels for Roller Skates,
Velocipedes, and Road Vehicles.
We, FRANK IORNS GIBBS and WILLIAM WRIGHT, trading together as
Gibbs & Wright, of 70, Lower Hurst Street, in the City of Birmingham, Tinplate
Workers and Metal Platers, do hereby declare the nature of this invention to be as
follows:
-
This invention consists of the hereindescribed improvements in tyres and wheels
for roller skates velocipedes and road vehicles one object of our invention being to
provide a tyre which will have a certain amount of elasticity and yet will not be
liable to puncture.
One form of our improved tyre is composed of disc like or other short sections
of cork indiarubber basil leather or of any two or more of these substances or of
other suitable soft substance or substances threaded on to an annular core of wire
or strip metal or tube indiarubber or other substance which thus holds the said
short sections together forming an inner portion for an elastic tyre of the proper
size to fit on to the wheel rim. This inner portion of the tyre is covered with one
or more layers of canvas, or indiarubber, or indiarubber insertion or other suitable
The said core is
material which is secured thercon by lacing or by other means.
by preference made into a complete ring before the sections are threaded thereon
and in this case each of the sections has to have a side slit to enable it to be
threaded on to the corc. When the said core is made of wire or other unstretchable
substance then the wheel rim has to be made in halves divided in a plane at
right angles to the axis so as to enable the tyre to be placed in position on the
wheel rim.
When the outer covering is secured by lacing the lace may be arranged around
the periphery and is by preference formed of one or more wires covered with india-
rubber; the lace will then also serve the purpose of preventing the wheel or roller
from skidding or otherwise slipping. To prevent dirt working into the tyre through
the eyeletted lace holes a thin strip of rubber or other material like a tongue is or
may be provided inside the outer covering.
When the elastic tyre is made as above described we may make the central
metal core of the tyre so strong that a separate wheel rim is not required; and in
this case the outer ends of the spokes are fixed to the said core.
According to another arrangement of this invention which is applicable more
particularly only to the rollers of roller skates we make the inner part of the said
tyre as a ring of cork or felt or other suitable substance turned to a circular
or other shape in cross section all in one piece or in sections glued together and in
this case we may dispense with the said core.

We, FRANK IORNS GIBBS and WILLIAM WRIGHT, trading together as
Gibbs & Wright, of 70, Lower Hurst Street, in the City of Birmingham, Tinplate
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 is applicable more particularly to the wheels or rollers for roller
skates but the said invention can also be applied to the wheels of velocipedes and
road vehicles. The principal object of this invention is to provide a tyre which
will have a certain amount of elasticity and yet will not be liable to puncture.
We will describe our invention by referring to the accompanying drawing on
which
Fig. 1 represents a wheel or roller for a roller skate having its tyre constructed
according to this invention; Fig. 2 is a cross section of the same;
Fig. 3 is a face view and Fig. 4 is a cross section of one half of the cork ring
forming the inner part of the tyre;
Fig. 5 shews the strengthening core of the said inner part separately;
Fig. 6 shews a modified form of the cork ring;
Fig. 7 is a part section face view and Fig. 8 is a cross section of a wheel or
roller provided with a modified form of our said tyre; Fig. 9 shews a part of the
indiarubber outer covering of the same separately;
Fig. 10 is a part section face view and Fig. 11 is a cross section of a wheel and
tyre formed according to another part of our invention.
Our said improved tyre consists of a ring of cork A made in any of the various
ways as hereinafter described and of a size to fit round the wheel rim and enclosed
by an outer covering B of indiarubber or indiarubber insertion. The said cork
ring A is by preference made in halves (marked respectively a¹ a²) as shewn in
Figs. 2, 3 and 4 the division being central in the plane of the ring. Both of these
half rings has a groove a³ turned in it to receive a tubular or wire ring C forming
a strengthening core for the same. The wheel or roller is one of that kind which
is made in halves D' D* divided centrally at right angles to the axis so as to allow
of the tyre being placed in position round the rim. The outer covering B which
is made of indiarubber or indiarubber insertion is made of a shape to cover that
part of the cork ring A which is outside the rim and also to extend for some little
distance between the inner surfaces of the cork ring A and the wheel rim. In
making up the tyre and wheel the tubular or wire ring C has first to be enclosed
between the two halves of the cork ring A which latter is then placed in position
in the outer covering B which will stretch to allow of this. The said ring A with
the outer covering B upon it are then placed in position between the halves of the
wheel which latter are then screwed or otherwise fixed closely together so as to
clip the outer covering B and cork ring A. and thus secure the same together.
Each of the halves a' a² of the cork ring may be built up of two or more sections
glued or otherwise cemented or fixed together; or the cork ring A may be turned
up,solid out of one piece of cork as shewn in Fig. 6 or be built up in sections
glued or otherwise cemented together and in this case the core C may be dispensed
with.
In the example of our invention shewn by Figs. 7 and 8 the cork ring is made.
up of six sections marked respectively a' as a as a fitted together in the outer
covering B so as together to form the complete ring. These Figs. 7 and 8 also
shew a modified form of the outer cover B which is of the kind well known made

page_text: with projecting annular side ribs with which the flanges d' of the halves
of the wheel engage and thus effectually prevent the outer covering B from getting
out of place.
When our improved tyre is made with the inner annular metal core C the rim
of the wheel may be dispensed with as shewn in Figs. 10 and 11. This core C of
the tyre is then made so strong that a separate wheel rim is not required and in
this case the outer ends of the spokes e are fixed to the said core C; this is done
before the pieces of cork forming the inner portion of the tyre are fixed round the
core. In this form of our invention the outer covering B is preferably secured by
its edges being secured by lacing as in some pneumatic tyres.
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. The hereindescribed improved tyre for the wheels of roller skates, velocipedes
and road vehicles, consisting of an inner cork ring adapted to fit round the wheel
rim and enclosed in an annular outer covering of indiarubber or indiarubber
insertion said cork ring being strengthened by an inner metal ring C or not so
strengthened, substantially as set forth.
2. The hereindescribed improved tyre for the wheels of roller skates, velocipedes
and road vehicles, consisting of an inner cork ring A made in halves in a plane at
right angles to the axis of the wheel and enclosing a metal ring like core C and
enclosed by an annular outer covering of indiarubber or indiarubber insertion,
substantially as set forth.
3. The combination with a wheel or roller for roller skates, velocipedes and road
vehicles made in halves in a plane at right angles to its axis, of a tyre consisting
of cork ring fitting around the rim of said wheel and an annular indiarubber or
like outer covering enclosing said cork ring and gripped by the flanges of the wheel
rim, substantially as set forth.
4. The combination with the wheel made with a tubular rim C, of a cork ring
like tyre enclosing the same said cork ring being itself enclosed by an indiarubber
or like outer covering substantially as hereinbefore described and illustrated by
Figs. 10 and 11 of the accompanying drawings.
