Improvements in or relating to Wheel Rims and Tyres for Cycles
and other Vehicles.
We HUGH FAULKNER of Rockleigh, London Road, Leicester & ALFRED
HENRY FAULKNER of 18 Hinckley Road, Leicester, Manufacturers do hereby
declare the nature of this invention to be as follows:-
This invention has reference to wheel rims and tyres for cycles and other
vehicles, and is particularly applicable to pneumatic tyres and wheel rims for use
therewith.
The first part of the invention consists in forming the wheel rim of a curvilinear
or approximately semi-circular section with the ends turned under in a horizontal
plane.
The canvas and india-rubber covering of the air tube and the outer rubber
envelopes are formed with combined thickened or enlarged sides or edges which are
contained within the rim so that when the tyre is inflated it will fit tightly
therein.
The outer rubber envelope is also considerably thickened at the part where
it meets the horizontal portion of the rim so as to form a pad or protector
which in the event of the tyre becoming punctured will permit of the machine
being ridden without fear of the tyre and air tube being cut by the rim.
The second part of the invention relates to a wheel rim provided with a fork
or jaw on each side between which the sides of the outer rubber envelope and
its connective canvas lining may be located and gripped or held therein by
wedge or other suitably shaped preferably metal strips or their equivalents and
also if desired by screws passing through the same and through the whole or a
portion of the rim jaw.
The canvas lining may also be provided with an internal tongue or flap which is
inserted between the air tube and the protective pad next or adjacent to the
wheel rim.
The wheel rim with the fork or jaw on each side may be formed in several
ways.
A convenient form may consist of two superposed plates bent or formed to the
requisite contour and connected together by screws or other suitable means.
Or the forked rim may be formed by two slightly curved plates held. apart by
two laterally disposed Ŭ shaped plates, each having a side wing or extension
between which the ends of the said curved plates may be held.
In one modification, one of the two plates forming the rim may be slightly curved
to form a spring plate and it may further be connected to the other plate by screws,
rivets, welding or other means.
The said spring plate may also be formed in transverse or longitudinal sections
or both of such sections if desired.
Another form of the invention may consist of a wheel rim of curved section
partly overlapped at each side by the sides or edges of the outer envelope and a
superposed steel strip or band, preferably sectional, secured together by screws
passing through the same.
The canvas flap or tongue hereinbefore referred to may be inserted between the
air tube & its protective pad on the rim.

Improvements in or relating to Wheel Rims and Tyres for Cycles
and other Vehicles.
We, HUGH FAULKNER of. Rockleigh, London Road, Leicester and ALFRED
HENRY FAULKNER, of 18 Hinckley, Road, Leicester, Manufacturers, 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 wheel rims and tyres for cycles and other
vehicles and is particularly applicable to pneumatic tyres and wheel rims for use
therewith.
The first part of the invention consists of forming the wheel rim of a curvilinear
or approximately semi-circular section with the ends turned under in a horizontal
plane.
The canvas and india-rubber covering of the air tube and the outer rubber
envelopes are formed with combined thickened or enlarged sides or edges which
are contained within the rim so that when the tyre is inflated it will fit tightly
therein.
The outer rubber envelope is also considerably thickened at the part where it
meets the horizontal portion of the rim so as to form a pad or protector which in
the event of the tyre becoming punctured will permit of the machine being ridden
without fear of the tyre or air tube being cut by the rim.
The second part of the invention relates to a wheel rim provided with a fork, jaw,
or recess on each side between which the sides of the outer rubber envelope and its
connective canvas lining may be located and gripped or held therein by wedge or
other suitably shaped preferably metal strips or their equivalents and also if desired
by screws passing through the same and through the whole or a portion of the
wheel rim jaw.
The canvas lining may be provided, also, with an internal tongue or flap which
is inserted between the air tube and the protective pad or between the latter and
the wheel rim.
The wheel rim with the fork, jaw or
several ways..

means.
Or the forked rim may be formed by two slightly curved plates held apart by
two laterally, disposed Ŭ shaped plates, cach having a side wing or extension
between which the ends of the said curved plates may be held.
In one modification one of the two plates forming the rim may be slightly curved
to form a spring plate and it may further be connected to the other plate by screws,

The said spring plate may also be formed in transverse or longitudinal sections
or both of such sections if desired.

JUS
The canvas flap or tongue hereinbefore referred to may be inserted between the
air tube and its protective pad or 'the latter and the wheel rim.
The invention will be more fully understood from the annexed drawings in
which
Figures 1, 2, 3, & 4 are sections of wheel rims and tyres constructed in accordance
with our invention, and,
Figures 15A 5B 24 and 1ª are sections of the respective wheel rims.

page_text: Referring to Figures 1 and 1^, A is the air tube, B the outer rubber covering
and C the canvas and indiarubber lining of the latter.
D is the wheel rim of curved section with the ends D' turned under in a horizontal
plane and E E are the wheel spokes.
F is a pad, formed by preference of canvas and rubber and laid around and
within the wheel rim so as to be interposed between the latter and the tyre.
It will be noticed that the canvas and rubber lining C has its sides or edges
formed of several thicknesses cemented together to form an enlargement which
when the tyre is inflated will fit tightly within the rim.
D' represents the division between the two edges of the outer covering.
The rubber outer covering B is also constructed of additional substance at the
part B where it meets the horizontal portion of the tyre, so that in the event of
the tyre becoming punctured and collapsing such thickened portion will form a
cushion or support for the wheel rim and thus enables the bicycle or other vehicle
to be ridden without cutting the tyre, which frequently takes place in other forms
of tyres.
Referring to Figures 2, 24, and 2B, A is the air tube, B the outer rubber
covering and C the canvas and rubber lining of the latter.
The wheel rim has a fork, jaw, or recess on each side or edge for the reception of
the edges of the outer covering as hereinafter described.
In Figure 2, the wheel rim may consist of two curved plates G G held
apart by two laterally disposed U shaped plates H formed with a side wing or
extension H parallel thereto between which the plates G G¹ are brased or
otherwise held.
The two plates H thus form the jaw or fork between which the thickened sides
or edges of the outer covering are located, the latter being secured in position
by sectional wedge shaped plates J or their equivalents pressed into the jaw
formed by the plate H and secured therein by screws J' passing through the said
plates H & J as shown.
A modification of this wheel rim may consist of two plates K K', as shown in
Figure 2B, cranked at each end so that when placed together as shown, and
secured by a rivet K', or otherwise, a fork or recess may be formed, for the
reception of the edges of the outer covering of the tyre as hereinbefore
described.
Additional means consisting of tongues or flaps L are provided to hold the
outer covering of the tyre in position on the wheel rim.
This tongue or flap L is preferably of canvas and is cemented at one end to
the lining of the outer covering and by preference is located between the air
tube A and the protective pad F so that when the tyre is inflated the said tongue
is held firmly in position.
If the pad F be not employed the said tongue will be placed between the air
tube and the wheel rim as will be readily understood.
A further modification of the wheel rim just mentioned is illustrated in
Figures 3. 34.
The pneumatic tyre used in connection therewith may be the same as shown and
described with reference to Figures 2. 24 2.
The rim consists of a curved plate over which may be placed a compound curved
or spring plate D³ preferably of the shape shown and connected to the plate D³ by
rivets D or other means.
The spring plate may be formed in sections transversely, i.e. across the width of
the rim or longitudinally in the direction of the circumference of the rim or in both
of such ways if desired.
The edges of the outer covering are placed between the said plates D'D' and
screws C passing through the said plates and the outer covering when tightened
hold the tyre in position on the rim.
For heavier traffic we may use a wheel rim (Figs. 4. 44) consisting of a curved
plate over which the sides or edges of the outer covering of the pneumatic tyre

page_text: may be laid and secured thereon by superposed steel plates M or equivalent and
screws M¹ passing through the same and into the plate D.
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. In a pneumatic tyre for vehicle wheels the combination with the air tube of
an outer covering formed with enlarged sides or edges to fit into a wheel rim and
also formed of increased substance at the part which is in contact with and supports
the said rim substantially as and for the purpose described and illustrated in
Figures 1 and 14 of the accompanying drawings.
2. The combination of a wheel rim the edges of which are turned inwardly in a
horizontal plane and a pneumatic tyre the outer covering of which is provided with
enlarged edges to fit within the said rim and formed also of increased substance at
the part in contact with the horizontal portion of said rim substantially as and for
the purpose described.
3. A pneumatic tyre for vehicle wheels consisting of an air tube outer covering,
tongues or flaps thereon adapted to be gripped between the said air tube and the
wheel rim substantially as and for the purpose described.
4. A pneumatic. tyre for vehicle wheels consisting of an air tube, protective
pad, outer covering, tongue or flap thereon adapted to be gripped between said
air tube and protective pad, and a wheel rim provided with a jaw or recess on each
side to receive the edges of the said outer covering, substantially as and for the
purpose described.
5. A wheel rim provided with a fork, jaw or recess on each side to receive the
edges of the outer covering of a pneumatic tyre and means for securing the said
outer covering in position on the wheel rim substantially as described.
6. A wheel rim consisting of two slightly curved plates such as G. G' connected
together by two laterally disposed U shaped plates such as H provided with side
wings or extensions H' parallel thereto substantially as described.
7. A wheel rim consisting of two plates flattened at their central portions and
cranked at their outer ends so that when rivetted or otherwise secured together a
fork, jaw or recess is formed in each side thereof substantially as and for the
purpose described and illustrated in Figure 2B of the accompanying drawings.
8. The combination with a pneumatic tyre of a wheel rim provided with a fork,
jaw or recess on each of its sides to receive the edges of the outer covering
of said pneumatic tyre, sectional wedge plates such as J or equivalent and
screws for fixing the said outer covering on the said rim substantially as
described.
9. A wheel rim consisting of a plate and a superposed plate or plates between
which the edges of the outer covering of a pneumatic tyre are adapted to be gripped
substantially as described and illustrated in Figures 3. 3^ 4. 4ª of the accompanying
drawings.
10. The combination with the outer covering of a pneumatic tyre of a wheel
rim overlapped thereby and one or more superposed plates fastened thereover
substantially as described and illustrated in Figures 3. 34 4. 44 of the accompanying
drawings.
