Improvements in Bicycles or other similar Vehicles Propelled by
Oil or equivalent Engines.
I ANTHONY GEORGE NEW of Palace Chambers Westminster Electrical Engineer
do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to enable bicycles which are driven by oil or
equivalent engines to be made of considerably lighter construction than has hitherto
been the practice while at the same time retaining all existing fly wheel advantages of
weight or increasing them.
In order that an oil-engine-propelled bicycle may act satisfactorily and continue to
run even at slow speeds it has had hitherto to be made of such a weight as to produce
sufficient fly-wheel-effect in virtue of its momentum as shall enable the pistons of the
oil engine to compress the mixture of oil vapour and air to a sufficient degree to
permit an efficient explosion. It is now proposed to make the bicycle itself of lighter
construction and to adopt one or more fly wheels-preferably one on each side of the
driving wheel. For this purpose the driving wheel is mounted to revolve freely on an
axle and the two fly wheels are mounted rigidly on this axle. The axle is fitted at
either end with the cranks on to which the engine connecting rods work. Suitable
gearing such as a gearing similar to the back centre gearing of a lathe or a sun and
planet wheel motion or differential gearing is employed to transmit the energy from
the axle to the driving wheel and with the special object of enabling the axle to
revolve at a greater speed than the driving wheel or wheels. The driving wheel as an
alternative arrangement may of course be fixed to the axle and fly wheels, with cranks
attached, may be mounted to revolve freely on prolongations and in this case inter-
mediate gear
would be also employed. By this means the fly wheels can be made of
considerable lightness as they revolve considerably faster than the driving wheel and
hence the total weight of the machine is greatly decreased. The oil engine cylinders
may of course be situated either between the driving wheel and the steering wheel or
any other convenient position.

I ANTHONY GEORGE NEW of Palace Chambers Westminster Electrical Engineer 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:-
The object of the present invention is to enable motor cars to be constructed in a
lighter manner than has hitherto been accomplished, whilst retaining all the advantages

page_text: caused by a heavy machine with regards to mouentum (for obtaining a perfect com-
pression of the explosive charge in the cylinders) by means of one or more fly wheels
or crank discs suitably mounted, on the shaft of the driving wheel, for example, of a
bicycle or tricycle driven by a petroleum engine. Those fly wheels may either be
mounted rigidly on the driving shaft and connected with the road wheel by inter-
mediate gear or the road wheel may be mounted rigidly and the fly wheels loosely and
similar gear provided, on the shaft. By means of this intermediate gearing which
may consist of an epicyclic train or a sun and planet style of gear I can provide for
various speeds of travelling or reversing or both whilst allowing the engine to run at
its ordinary high speed :-
And in order that the invention may be more clearly understood reference will now
be made to the accompanying drawings, wherein :-
Fig. 1 is a half section of the driving wheel of a motor tricycle or three
wheeled dog cart with a fly wheel mounted on either side & rigidly connected with
the shaft.
Fig. 2. is a half section of the driving wheel of a motor cycle with one fly wheel
concentric therewith.
Fig. 3. is a diagram of the slow speed gear wheels and brake band.
Fig. 4. is a diagram of the high speed gear wheels serving also to illustrate part
of the reversing gear.
Referring to Fig. 1. A. represents the axle whilst B. B. are two fly wheels rigidly
mounted thereon & connected by interinediate gear C. C. to the driving wheel D. of
the cycle. The fly wheels B. carry crank pins B1. to which the connecting rods of
the explosion cylinders are coupled in the usual manner. The intermediate gear C. C.
may be arranged to, suit various requirements, for example as shown in Fig. 1
when one of the straps F. is tightened around the internally toothed drum G. the
cog H. will cause the pinion 1. to be carried round at a slower speed than the axle A.
& when G 1. is held stationary the internal toothed wheel Q. will cause the pinion N.
to travel around the cog wheel M. keyed on the boss of G 1. As the pinion N. is
mounted within the hub D 3. the road wheel D. will thereby be caused to rotate.
To obtain a slower speed the dram G 2. is held fast & the train of gears H. I. J. K.
gearing with the internal teeth thereof causes the road wheel to rotate accordingly,
the wheel K. being mounted on the hub of the wheel D. in a similar manner to N.
before described.
To reverse the direction of rotation of the road wheel the drum G 3. is held by its
straps F. & two or more sets of pinions similar to N & O. Fig. 4. are mounted on rotating
arms which will be carried around in the direction of the arrow Z. Fig. 4. These arms
can be connected to the road wheel in any suitable manner in order that it will rotate
in the same direction as the said arms. The wheels N & O in this case being rotated
around the shaft A A. cog M. Fig. 1. is keyed on the tube W. which also carries the
pinion 1. cog M, cog J. & internally toothed wheel Q & also provides a bearing for
other parts of the mechanism.
In Fig. 2 is shown a driving wheel D so constructed as to enclose a fly wheel B.
within its walls D 1. formed preferably of aluminium.
This fly wheel is keyed to the shaft as at B 2. which carries at either end a crank E.
to which the connecting rods of the engine are coupled as in the previous example.
To transmit the motion from the driving shaft to the road wheel I prefer to make use
of the following device :-A brake band F. encircling an internally toothed drum G.
engaging a pinion 1. which gears with the cog H. keyed on the shaft A. The pinions I.
are carried by arins extending from the boss of a second cog J. free to rotate on
shaft A. which in its turn engages a second pinion K. mounted on a short spindle D 2.
of the road wheel D. When the brake band F. is tightened around the drum G. by
means of a lever I. Fig. 3. pivotted on the forks T. of the driving wheel the result
will be that the wheel D. will rotate at a slower rate than the shaft A. owing to the
intervention of the gear H. I. J. K.
On the right hand side of Fig. 2. is shown a cog M. keyed to the shaft A. which causes
a fuster rotation of the wheel D. by means of the intermediate pinions N. O. carried

page_text: by arms extending from a boss P. when the drum Q. is prevented from rotating:
the boss P & drum Q. being keyed together as shown.
The road wheel D is provided with an internal toothed wheel D 3. with which
the pinion O. engages & so causes the wheel D. to rotate in the direction of the
arrow D.
A cbain wheel R is keyed to an extension of the road wheel for preference in
order that the usual foot-pedal mechanism may be used for starting the motor after
which the chain is thrown out of gear.
In the axle A. & forks T. are provided perforations or grooves t. by means of which.
the mechanism may be lubricated.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is
1. In cycles driven by explosion engines the use of a fly wheel or fly wheels.
mounted concentrically on either side of the road wheel D. whereby a perfect com-
pression of the explosive charge is obtained thus permitting a light construction of
machine, such fly wheels & road wheel being preferably connected by intermediate
gearing as & for the purpose herein shown & described.
2. In cycles driven by explosion engines the use of a fly wheel such as B. mounted
concentrically within a road wheel D. & connected therewith by intermediate gearing.
as & for the purpose herein shown and described.
