I, WILLIAM LAWRENCE BAILLIEU, of Melbourne, Victoria, but at present of
Nos. 97 and 98, Bishopsgate Street Within, in the City of Londen, Accountant,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the driving mechanism of safety bicycles in which
chain wheels are employed and has for its object simplification of parts, the applica-
tion of the power directly to the chain driving wheels instead of through the
medium of a crank. The construction of the hub and pinion of the driving road
wheel so that the pinion may be more readily removed and replaced by another
when change of gear is desired and so that the flange receiving the spokes on the
pinion side of the driving road wheel is made integral with the part of the hub to
which the pinion is attached in such manner that the power is transmitted as
directly as practicable from the periphery of the pinion to the largest diameter
of the hub.
The driving chain wheel which is secured to the axle of the machine in the usual
manner has one of its arms strengthened and formed with a longitudinal slot (or if
desired with one or more holes) to receive the end of an ordinary pedal spindle
which is secured within the slot by ordinary means.
The hub of the driving road wheel is formed with projecting arms the ends of
which are made integral with a ring or flange receiving the spokes of the wheel.
The arms are each constructed with holes to receive bolts for securing the pinion
which is made in the form of a ring with projecting lugs or cars drilled to receive
the bolts.
By connecting the pedal spindle directly to the chain wheel, the necessity of a
crank on that side of the machine is dispensed with, while the power is transmitted
more directly to the periphery of the chain wheel.
The construction of the hub and pinion of the driving road wheel enables the
pinion to be more readily substituted for another than hitherto while the power
is transmitted more directly from the periphery of the pinion to the largest
diameter of the hub near to where the spokes are connected.

I, WILLIAM LAWRENCE BAILLIEU, of Melbourne, Victoria, but at present of
Nos. 97 and 98, Bishopsgate Street Within, in the City of London, Accountant,
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 the driving mechanism of safety bicycles in which
chain wheels are employed and has for its object simplification of parts, the applica-
tion of the power more directly to the chain driving wheels instead of entirely
through the medium of a crank. The construction of the hub and pinion of the
driving road wheel so that the pinion may be more readily removed and replaced
by another when change of gear is desired and so that the flange receiving the
spokes on the pinion side of the driving road wheel is made integral with the part
of une hub to which the pinion is attached in such manner that the power is trans-
mitted as directly as practicable from the periphery of the pinion to the largest
diameter of the hub.
Referring to the accompanying drawings in which similar letters of reference
indicate the same parts in both figures.
Fig. 1 is a side elevation of the driving-chain wheel and pinion applied to a
portion of a bicycle, and
Fig. 2 a section of the pinion and a portion of the hub, taken on the line x-x
Fig. 1.
The driving chain wheel a which is secured to the axle of the machine in usual
manner has one of its arms strengthened and formed with a longitudinal slot b
(or if desired with one or more holes) to receive the end of an ordinary pedal
spindle which is secured within the shot by ordinary means.
The hub c of the driving road wheel is formed with projecting arms d the ends
of which are made integral with a ring or flange e receiving the spokes of the
wheel.
The arms d are each constructed with holes f to receive bolts for securing the
pinion which is made in the form of a ring with projecting lugs or ears i drilled
to receive the bolts g.
In my invention by connecting the pedal spindle directly to the chain wheel,
the necessity of a crank on that side of the machine is dispensed with while the
power is transmitted more directly to the periphery of the chain wheel.
The construction of the hub and pinion of the driving road wheel enables the
pinion to be more readily substituted for another than hitherto while the power is
transmitted more directly from the periphery of the pinion to the largest diameter of
the hub near to where the spokes are connected.
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
_
1. In a safety bicycle the employment of a chain driving wheel having one of its

page_text: arms provided with a longitudinal slot to receive the end of a pedal spindle, substan-
tially as and for the purposes herein described and illustrated.
2. In a safety bicycle the hub of the driving road wheel upon the pinion side
constructed with projecting arms the extremities of which are made integral with
the ring or flange receiving the spokes, slots within the arms receiving bolts by
which the pinion is attached, substantially as and for the purposes herein described
and illustrated.
3. In bicycle gearing the combination of the ring pinion h connected by bolts g
with the hub e carrying the flange e, substantially as specified and illustrated.
4. The construction or arrangement in combination of the parts of an improved
bicycle gearing, as and for the purpose set forth and shewn by the drawings.
