COMPLETE SPECIFICATION.
Improvements in Bicycles and like Vehicles.
I, GEORGE SCATTERGOOD, Stapleford, Nottinghamshire, Bicycle Manufacturer,.
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:
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an outer side view of a driving wheel, and pedal axle arm in one
piece.
Figure 2 a plan of the same.
Figure 3 shows an outer side view of a driving wheel and pedal axle arm con-
nected by a dovetail joint.
Figure 4 a plan of the same, and
Figure 5 a central sectional view on the line A A Figure 3.
Figures 6, 7 and 8 are central sectional views showing three ways of connecting
a driving wheel and a pedal axle arm.
My improvements consist in casting or forging the driving wheel 1 and pedal
axle arm 2 in one piece as shown at Figures and 2 if of the same material.
Or if the wheel 1 is formed of brass, wrought iron, malleable iron, or other
metal, and the pedal axle arm 2 of steel, they may be joined together so as to
form one piece by dovetailing the arm into the boss of the wheel, as shown at
Figures 3, 4 and 5.
Or the arm 2 may be interiorly screw threaded and screwed onto the exteriorly
screw threaded boss of the wheel 1 as shown at Figure 6.
After being screwed together a small hole is drilled through the arm and wheel
into which a pin is driven and rivetted down at each end to prevent unscrewing.
Or the boss of the wheel 1 may be screw threaded interiorly to receive the
exteriorly screw threaded part of the boss of the arm 2 as shown at Figure 7. A
hole being drilled through the wheel and arm, and pin inserted and rivetted as
before described.
Or the boss of the wheel 1 may be turned and the boss of the arm may be bored
out and shrunk on the boss of the wheel and held in position by one or mora
screws 4 as shown at Figure 8.
Or the arm 2 may have a somewhat longer boss turned down, and the boss of the
wheel be bored out and shrunk on the arm.

page_text: Or the bosses of the wheel and arm may be made polygon shaped and fitted
together to form one piece.
Either of the above described wheels and arms may be secured on the r dal axle
by a tapered key being driven into a keyway 5 shown at Figure 3 inste d of as
heretofore employing two keys, one to secure the wheel on the axle and a other to
secure the arm.
Or the wheel and arm may be secured on the axle by a wedge shaped bolt 6
screw threaded and provided with a nut as shown at Figures 1 and 2 enabling a
rider to detach the wheel and arm from the axle to alter the gear of his machine
in a few minutes.
:
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:-
The construction and employment of driving wheels and pedal axle arms for
bicycles and like vehicles in one piece substantially as described and illustrated in
the drawings annexed.
