COMPLETE SPECIFICATION.
Improvements in Wheels for Vehicles, Pulleys, and the like.
We WILLIAM CHRISTOPILER WHITE Contractor, FRANK CORRIE, Sharebroker, and
JOHN DUNMORE CAMPBELL, Merchant, all of Brisbane, in the Colony of Queens-
land 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 wheels and is designed with the object
of combining lightness and strength, low cost of production and an easy means of
effecting repairs, more especially the replacing or renewing of broken spokes.
Figure 1. Represents elevation of wheel.
Figure 2. Sectional elevation.
Figure 3. End view of hub showing mode of securing spokes.
Figure 4. is a modification showing alternative mode of securing spokes.
Figure 5. Segment of rim and flange showing mode of fixing spokes thereto.
Figure 6. Section of expanding hub for cycle, pulleys and vehicle wheels.
Figure 7. Section of expanding hub for wheels with mail or tapered axles,
part of which is applicable to cycle hubs.
Figure 8. Segment of rim and flange, showing the spokes as an integral part
of same.
The reference letters apply to corresponding parts in the various figures.
A is the rim, B the flange, C the spokes, D the expanding hub.
For cycles, perambulators and such like wheels, the rims and flanges are stamped
out of sheet metal (preferably steel) in two halves rivetted or otherwise secured
together as shewn at a the rims may be moulded to any desired shape to receive
any particular form of rubber or other tyre: for ordinary vehicle or implement
wheels, or machinery pulleys the rims are formed of T shaped metal or two rings
of angle metal rivetted or otherwise secured together to which are suitably secured
the iron tyres for vehicles and metal rims for machinery pulloys. The spokes may
form an integral part of the flange and rim by being stamped out of sheet metal
as shown in Fig. 8 or may be entirely separate parts as shown on Figs. 3, 4 and 5.
In Figs. 3 and 6 E is a circular disc forming an integral part of the cup or ball
race on one end of the hub and E is a separate part secured to the hub by set
screw e: on these discs are projecting lugs f f f etcetera with undercut groove
as shewn in dotted lines Fig. 3 and in section Fig. 6 the spokes used with these
discs E and E are stamped out of sheet metal with projecting ends, the spokes

page_text: fit into the spaces between the lugs f f f etc. and the projecting ends into the
undercut groove.
Figure 4 shows a modified form of securing the spokes in this modification the
end of the spokes are made with egg shaped holes fitting over metal
studs g g g etc. on circular disc I', both ends of the spokes may be made the
same and similarly secured to the flange of the wheel by metal stud g³, in Figure 5.
The expanding hub in Figure 6 is made in two parts, G is a sleeve with female
screw and G¹ metal tube with male screw utting into female screw (the screws are
not shewn on drawings) H and H' are extended bosses forming ball races, 4 and 4
the balls, and the cones on axle, one of which may be solid with the axle,
and one screwed on for adjusting. K square, octagonal, or hexagonal shoulder to
receive spanner for contracting and expanding the hub as required, L lock nut
L washer-One side of the metal tube G is flattened to prevent washer from
turning, the hole in the washer being made to correspond.
In Fig. 7 M is the axle, M' the axle box fitted in hub N having flange into
which is fitted two or more adjusting screws O and O', P set screw for securing
axle box and hub, Q and Q leather washers Fand discs for receiving spokes
with lugs or studs as in Figs. 3 and 4 It cap.
The spokes of the wheels alternately cross from the flange to the hub as shewn in
Figs. 2 and 8 and may be made with egg shaped holes on either end, or egg shaped
holes where fitting on to flange and projecting ends at the hub and when forming
an integral part of the flange and rim, the ends for attachment to hub may be
of either pattern.
In using this invention when fitting on the spokes or replacing a broken one, the
hub in Fig. 6 is contractes by means of a spanner on shoulder h, when all spoks
are fixed in their respective positions, the hub is expanded by the same means
and all the spokes made taut at once the wheel becoming perfectly rigid: in Fig. 7
the adjusting screws 0 and O' are slackened when the disc F will easily slide on
the axle collar thus allowing the fixing of the spokes on the two discs, the hub
is then expanded by the adjusting screws O and when all become taut and th
wheel rigid. In order to admit of the rotation of the part G of the hub, the
setscrews e must be removed, so as to disconect the disc E and the part G.
The great advantages in this invention are, that in cycle or other light wheels,
the spokes can be made of ribbon steel, and carried in the pocket by the rider,
and in the event of a broken spoke easily replaced by a new spoke without the
assistance of a mechanie, and in vehicle wheels the renewal of a spoke does not
necessitate the wheel being removed from the vehicle and obviates the possibility
of damaged felloes so often occurring in wooden wheels, the tyres also are not
subject to getting stack in dry weather, thus requiring their being taken off,
cut, and re-shut with consequent damage to the wheel; wheels constructed on this
principle could for vehicles be made much lighter than wooden wheels of equal
strength.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. In improvements in wheels such as described the detachable and semi-
detachable spokes as shewn in Figures 3, 4, 5, and 8.
2. In improvements in wheels such as described the dises E and E with
lugs as shown in Fig. 3 and the dises F and F with studs g g g as shown
in Fig. 4 as and for the purpose set forth.
3. In improvements in wheels such as described the studs in combination
with the rim A and flange B and spoke C as shown in Figure 5."
4. In improvements in wheels such as described, the combination of the
discs E and E, the bosses H and H' the sleeve G and the metal tube G' forming
the expanding hub as shewn in Fig. 6.

page_text: 5. In improvements in wheels such as described, the discs F and F', the flange n
and the adjusting screws 0 and 0 forming the expanding hub as shown in Fig. 7.
