COMPLETE SPECIFICATION.
Improvements in Wheels for Vehicles, and in Wheels and Pulleys
for Machinery.
We, WILLIAM CHRISTOPHER WHITE, Contractor, JAMES CAMPBELL,
Merchant, FRANK BERESFORD CORRIE, Stock and Share Broker, and JOHN
DUNMORE CAMPBELL, Merchant, all of Brisbane in the Colony of Queensland,
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 relates to improvements in the construction of wheels for use in
cycles, vehicles, machinery, agricultural implements and the like.
These improvements consist in constructing wheels of two pieces of sheet inetal
each half being stamped out of sheet metal forming one homogeneous whole, dispensing
with independent connections between spokes and hub, and spokes and rims in
cycle wheels, and dispensing entirely with separate felloes in vehicle wheels.
Reference is then made to the drawings in the specification, reference letters
apply to like parts in all figures.
Fig. 1 shews front elevation of cycle wheel.
Fig. 2 front elevation of machinery pulley.
Fig. 3 front elevation of vehicle wheel and
Figs. 4, 5 and 6 sections of Figs. 1, 2 and 3 respectively.
Fig. 7 part section of wheel boss or hub, shewing alternative fixing.
The wheels in all cases are constructed of two staniped metal conical discs,
preferably of sheet steel. A shews one of the discs forming half of the wheel
and A' the other half, these discs are placed face together and secured by clips a a¹
etretera, on the inner circle of the periphery of the wheel and form part of the
plates, each alternate clip being closed over in the opposite direction as shewn, and
in cycle wheels also by slots and clips bb etcetera, on the outside circle of the
periphery of the wheel, the slots and clips being alternately on each disc of the
wheel.
In vehicle or other wheel and machinery pulleys, these slots and clips bure
not necessary. In all descriptions of wheels and pulleys the two discs may be
rivetted together instead of being clipped together, as shewn in Fig. 3 at ffff
etcetera.
The flanges may be stamped to assume any desired form, such as a grooved like
rim for cycle wheels, as shewn at C in Fig. 4, and may be shaped or moulded to
receive any form of tyre, no additional face being required: in vehicle and other
wheels and machinery pulleys, the flanges are made rectangular as shewn at C¹
in Figs. 5 and 6, a metal rim or tyre, preferably of wrought iron is rivetted or
otherwise suitably secured on the flange as shewn at d and d' in these figures.
The bosses or hubs of the wheels are made of cast or wrought metal and of such
description adaptable for use in cycles, in pulleys working on shafting and in vehicle
or other wheels with mail or other axles, as shewn in Figs. 4, 5 and 6, the super-
structure of the wheel is secured to the boss or hub by means of set screws or by
screw bolts and nuts, in the latter case, some modification in the pattern of the
boss or hub is necessary, such as shewn in Fig. 7.
In all Figures 1, 2 and 3, the wheels are shewn with the spokes of the discs
opposite each other, if desirable the wheels may be constructed with the spokes
alternating between the spaces by stamping out the central hole in one disc in a

page_text: different relative position to the spokes than in the other disc so that when the discs
are connected together the hole coincides in both discs.
The spokes in the wheels may be stamped into a trough or semi-cylindrical form
from the inside of the wheel outwards, to give greater rigidity and a smooth
rounded surface on the outer side of the wheel.
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 :-
In improvements in cycle, vehicle, agricultural implement and machinery wheels
and pulleys, the construction of wheels and pulleys consisting of two perforated
conical plates stamped out of sheet metal suitably fastened or secured together
with spokes, rim, and central ring as parts of the whole, the central ring being
secured to the bub or boss; the rims being formed of suitable shape to receive
detachable rubber or other tyres as in Figure 4 or with flanges as in Figures 5
and 6 to which metal rims or tyres are respectively attached, as hereinbefore
described in the specification and illustrated by drawings.
Dated this 21st day of July 1896.
