Improvements in and relating to the Manufacture of Wheels of all
kinds, especially adapted for the Coggedor Toothed Wheels Used
in connection with Cycle Gearing and in Motor Cars, and for all
other suitable purposes.
We FRANZ WILLIAM POPP of 28 Ludgate Hill Birmingham Merchant, WILFRED
VAN WART of 582 Moseley Road Birmingham Metal Merchant and JOSEPH JOHN
BRADLEY of 16 Buckingham Street Birminghamn Metal Caster, do hereby declare the
nature of this invention to be as follows:-
Our object is to produce a cogged or toothed wheel especially adapted for use with
all kinds of cycles and cycle gearing and for motor cars and other vehicles where a
cogged or toothed wheel (or wheels) may be applicable, that shall be lighter in weight
than those hitherto used, yet of equal durability and practically as strong.
For our purpose we form the rim of the wheel (or wheels) and the cogs or teeth
upon the periphery of same in one piece of malleable or other iron, steel gun metal,
brass, nickel, or other suitable metal separately from the body or inner portion, which
latter is or may be composed of any suitable light and strong metal, such for instance
as any alloy, or alloys of aluminium, or of pure aluminium, we then attach the above
named cogged or toothed rim to the main body or inner portion of the wheel by a
process of casting, or by any other convenient process or method such as screwing,
riveting, soldering, or otherwise similar means may also be adopted for attaching the
cogs or teeth to the hub of the driving wheel, or to wheels of all kinds of cycles, motor
cars, and other vehicles as stated, and for wheels other than those having cogs or
teeth a similar method may be employed in their manufacture.

page_text: 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, reference
being had to the Drawings:-
The object of our present Invention is to produce wheels of all kinds applicable for
cycles Motor Cars, Carriages, and other Vehicles, and for other suitable purposes
which shall be lighter in weight than those which are at present in use, yet of equal
durability and practically as strong, and our improved manufacture of wheels is
particularly applicable for cycles and Motor Cars especially for the construction of the
cogged or toothed sprocket wheels for the gearing.
Referring to the Drawings.
Figure 1. Represents a toothed chain wheel according to our Invention.
Figure 2. Is a part Section taken through the rim and spoke on the line A. A.
Figure 3. Represents a Vehicle Wheel Constructed on a similar principle but
having additional strengthening rods intersecting the wheel rims spokes and centre
parts or hubs.
Figure 4. Represents a Cross Section of the wheel taken on the line B. B.
Figure 5. Is a view of one of the strengthening rods we employ in connection with
this latter method of our Invention.
In making say a cogged or toothed wheel we proceed thus. The rim A and coge
or teeth B upon the periphery of said rim are made separately from the inner portion
or body or spokes C and of different metal that is to say the rim and cogs are made in
one piece and may consist of malleable or other iron, steel, gun metal, brass nickel
or other suitable metal.
The centre portion and spokes and hubs of the wheels will be composed of any
suitable light and strong metal such as Aluminium or of any alloy, or alloys of
Aluminium, and we attach the cogged rim A to the inner portion C in any suitable
manner such as casting or by any suitable process, a convenient method which will
rigidly and effectually connect the parts will be by screwing or riveting the said rims A
to the inner portions, C and in order to provide for the contingency of the inner
centre portions of light metal possibly wearing at their centre bearings, (if they should
not be found sufficiently strong in themselves to withstand the strain imposed upon
them), we employ rings, centre collars, or bushes D of steel, bronze, gun metal, or
other suitable metal, which are applied to the Aluminium or Aluminium alloyed
centre portions C as follows:-
The centre collars or bushes D will be first cast to exactly fit their connections and
then laid into the impressions made in sand moulds formed by complete patterns of
the wheels to be constructed, so that the parts when attached shall form a perfect
wheel.
Thus it will be seen that the bearing centre portions will be protected and
strengthened (if needed) at those points where the strain and friction is greatest, and
when the hubs consist of the aforesaid light metal, similar steel, bronze, gun metal, or
other centre rings, or bushes, may be advantageously employed.
The above description refers to wheels of sizes suitable for the cycle trade, or to
wheels of smaller dimensions for other purposes; but for the construction of larger
wheels on the same principle either with or without cogs or teeth on the periphery of
the rims and for vehicle wheels where greater strength is required, we obtain
an increase of strength by applying wires or rods E to the rim C and rim
or tyre A and to the collars, rings, or bushes D, and connecting the same
by means of the wires, or steel or other metal rods E which pass through the
centres of the Aluminium, or alloyed Aluminium, or other light metal spokes, or
centre portions of the wheels, the said rods or wires being secured to the rims and
tyres CA and to the bushes, or collars D, or to other suitable parts of the wheels by
screwing, welding, brazing, forging, or by other methods, as inay be deemed to be
most likely to prove effective, preferably screwed in as shewn.
By the aforesaid means we are able to produce wheels for all purposes, that
obviously will be of much less weight than those hitherto used whilst preserving the

page_text: requisite degree of strength which will be found of great utility especially for
cycles.
Having now particularly described and ascertained the object and nature of this
our invention and in what manner the same is to be performed, we would have it
understood that we do not confine ourselves to the more precise details or to the
methods of construction herein specified as various modifications may be found
desirable without departing from the essential principle of our said Invention but we
declare that what we claim is :-
Firstly In wheels of all kinds for the herein described or for other suitable
purposes, constructing the outer rims, or the rims and cogs, or teeth, of inalleable or
other iron, or of steel, gun metal, brass, nickel or other metal, separately from
the inner portion, or spokes, and. hubs, of said wheels, and constructing said inner
portions of Aluminium, or of Aluminium and its alloys, attaching said outer rims to
the inner portions, or spokes, by screwing, riveting, or otherwise securing, said parts
each to each, as and for the purpose substantially as described.
Secondly-In wheels such as the chain gearing or sprocket wheels of cycles, motor
cars, and other vehicles, and wheels for other purposes, constructing the outer rims
and cogs of malleable iron, steel, gun metal, or other inetal, separately from the inner
part or spokes, of said wheels, constructing said inner part, or spokes, and hubs, of
Aluminium, or alloyed Aluminium, or other light strong ineral, in combination with
the application of rings, centre collars, or bushes, of steel, bronze, gun metal, or other
metal for the bearings, or frictional parts of said hubs, or centre parts, and attaching
the inner parts and outer rims to each other all combined and arranged substantially
as herein described.
Thirdly-In wheels, constructing the outer rims or tyres of iron steel, gun metal,
or other inetal, separately from the inner portion and spokes in combination with the
use of steel, or other rods, or wires, in connection with said inner and outer rims or
tyres and passing same through the Aluminium, or other light metal centre portion,
or spokes, and attached thereto and in connection with the centres of said inner
portions, or to the steel or other metal bushes, rings, or collars, and securing the
same as set forth and described.
Fourthly: We claim the special construction of wheels by the combination set
forth consisting of making the centre parts, or hubs, and spokes, comprising same, of
pure Aluminum or of any alloy or alloys of Aluminum, or other light metal, suitably
fixed within the outer metal rims as described or by equivalent means.
