Improvements in or connected with Wheels for Cycles and
other Vehicles.
We MARK BAILEY, of 41 Clarence Road, Wood Green, Electrician, and
JOHN WARNER, of 21 Osborn Street, Whitechapel, Ironfounder, both in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements in or connected with wheels for cycles or
other vehicles by which certain advantages are obtained.
In order that the nature of our invention may be more readily understood we
will describe by way of example one way in which we carry our invention into
effect and manufacture wheels for cycles and other vehicles.
Our invention consists of a wheel with an elastic tyre, made up of a number of
cylindrical segments, either hollow or solid, and of an elastic material such as
india rubber. These segments we arrange around the rim of the wheel in such a
manner that each segment is almost touching its adjoining segments and each
segment is arranged with its axis parallel to the axis of the wheel and transversely
to the rim of the wheel.
This arrangement of tyre necessitates a form of rin which differs from the
forms generally in use. Instead of the ordinary U shaped rim, with a curved bed
or bottom, we employ a ☐ shaped rim, with a flat bed or bottom, in which we fit a
corrugated band or tyre of steel or other suitable material.
The corrugations are formed to receive the elastic cylindrical segments and to
retain them in position without the use of cement. To this end we make the
corrugations somewhat more than semicircular in section. So that when the elastic
cylindrical segments are forced by compression into these corrugations they cannot
fall out in a direction transverse to their axes and they are prevented from coming
out in a direction with their axes by the flanges of the shaped rim.
It is obvious that we may vary the sectional form of our elastic segments
provided the corrugations of the corrugated band or tyre correspond in section
with that part of the elastic segments which they grip. And the ☐ shaped rim in
such a case it is obvious may be varied in section to accomodate itself to the
corrugated band or tyre.

COMPLETE SPECIFICATION.
Improvements in or connected with Wheels for Cycles and
other Vehicles.
We MARK BAILEY, of 41 Clarence Road, Wood Green, Electrician, and
JOHN WARNER, of 21 Osborn Street, Whitechapel, Iron Founder, both in the
County of Middlesex, 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 or connected with wheels for cycles or
other vehicles by which certain advantages are obtained.

page_text: In order that the nature of our invention may be more readily understood we will
describe by way of example one way in which we carry our invention into effect and
manufacture wheels for cycles and other vehicles.
Our invention consists of. a wheel with an elastic tyre, made up of a number of
cylindrical segments, either hollow or solid, and of an elastic material such as india
rubber. These segments we arrange around the rim of the wheel in such a manner
that each segment is almost touching its adjoining segments and each segment is
arranged with its axis parallel to the axis of the wheel and transversely to the rim
of the wheel.
This arrangement of tyre necessitates a form of rim which differs from the forms
generally in use. Instead of the ordinary U shaped rim, with a curved bed or
bottom, we employ a ☐ shaped rim, with a flat bed or bottom, in which we fit a
corrugated band or tyre of steel or other suitable material.
The corrugations are formed to receive the elastic cylindrical segments and to
retain them in position without the use of cement. To this end we make the
corrugations somewhat more than semicircular in section. So that when the elastic
cylindrical segments are forced by compression into these corrugations they cannot
fall out in a direction transverse to their axes and they are prevented from coming
out in the direction of their axes by the flanges of the ☐ shaped rim.
It is obvious that we may vary the sectional form of our elastic segments provided
the corrugations of the corrugated band or tyre correspond when seen in section with
that part of the elastic segments which they grip. And the ☐ shaped rim in such
a case it is obvious may be varied in section to accommodate itself to the corrugated
band or tyre.
In the accompanying drawings
Figure 1 illustrates a section of a part of a wheel constructed under my inven-
tion. A A are the cylindrical elastic seginents, B is a part of the rim, C is the
corrugated band and D D are the spokes.
Figure 2 is a transverse section of the rim, the corrugated band and segments
being omitted from the figure.
Figures 3 and 4 show in side and end elevation one form of the cylindrical
seginents employed.
It will be seen that the corrugated band C grasps the cylinders throughout more
than half of their circumference and that it consists simply of a metal ribbon bent
into the form shown in Figure 1. The cylindrical segments are placed in position
simply by squeezing them inwards between the bent parts c¹ c' of the corrugated
band.
Figures 5 and 6, show in side and end elevation another form of my segment and
Figure 7 shows in transverse section a part of a wheel with the said form of
seginent therein, the said figure corresponding with Figure 1. In this figure it will
be seen that the corrugated band takes a somewhat different forin when seen in
section in order to correspond with and grip the altered form of segment.
The corrugated band may be secured to the bottom of the rim by any convenient
means such for example as rivets at the parts c².
It is obvious that the corrugated band does not require to be continuous
throughout its whole length. Thus the only part of the corrugated band that is
of much use is the part as it is this part which keeps the segments in position
and if the parts c' are attached to the sides of the rim instead of to the bottom
thereof then the whole of the band between the said parts c' may be done away
with and the band reduced to a series of bridging pieces or pins passing across
from one side to the other of the trough-shaped rim and serving to hold the
segments in position. When it is desired to reduce the weight of the wheel then
it is preferable to cut away as much as possible of the corrugated band and leave
the segments to be held in position by such bridging pieces.
Although I prefer to attach ny elastic cylindrical segments in the way
inentioned, I may, when desired, attach them to the rim in any of the usual well
known ways that may be suitable as for example by cementing to the rim. When

page_text: I do away with the continuous corrugated band I prefer to allow the segments to
touch one another.
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. The improvement in or connected with wheels for cycles and other vehicles
consisting in the combination of a flat bottomed rim, a corrugated band therein and
a tyre consisting of a number of separate and detachable cylindrical segments
substantially as set forth.
2. The improvement connected with wheels for cycles and other vehicles
consisting in the elastic cylindrical segments substantially as set forth with
reference to Figures 5 and 6.
3. The improvement connected with wheels for cycles and other vehicles
consisting in a tyre formed of a continuous series of elastic cylindrical segments
set with their geometric axes parallel to the axis of the wheel itself substantially
as set forth.
4. The improvement connected with wheels for cycles and other vehicles
consisting in a tyre formed of a series of elastic cylindrical segments of the form
illustrated in Figures 3 and 4 and set with their geometric axes parallel to the
axis of the wheel itself.
5. The improvement connected with wheels for cycles and other vehicles
consisting in a tyre formed of a continuous series of elastic cylindrical segments
of the form illustrated in Figures 5 and 6 and set with their geometric axes
parallel to the axis of the wheel itself.
