PROVISIONAL SPECIFICATION.
Improvements Connected with Cycles or Vehicles Worked by Hand
or Foot Power.
We, FREDERICK BROUGHTON, of Elmers End, Beckenham, Kent, Engineer and
JAMES BENNETT, of 20 Bucklersbury, City of London, Metallurgist, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is:
1. To decrease the exertion of the rider in propelling the Machine during ordinary
travelling, and
2. To increase the propulsion effort in ascending hills, or while travelling over
uneven roads.
For the purpose of the first part of our invention, we make an extension in a piece
with, or attached to, the bracket in which the pedal axle is carried, said extension
being shaped to carry an additional axle on which at one end is a small chain wheel
and on the other a plain wheel.
The chain, say, from the rear driver of a Safety Bicycle gears into the small wheel
of the additional axle as well as with the ordinary chain wheel of the pedal axle and
communicates motion thereto. By this means the small wheel and the plain wheel
rotate at a higher speed than that of the pedals and the momentum thus given
is utilized for the onward motion of the machine with a reduction of labour to
the rider.
For the purpose of the second part of our invention, we attach weights or
blocks adjustable on or to the travelling wheels, such as on parallel spokes or to
the driver wheel of a Bicycle, Tricycle, or like Vehicle, the weight or block being
near to the periphery and at such parts that the pressure on the pedals shall
impart an additional thrust to the weight, so that as the foot of the rider is stretching
in following the pedal but not exerting a pressure, the weight is utilized for carrying
the wheel round until the rider's foot gives the necessary pressure for the next onward
thrust.
According to the third part of the invention, we so make the frame of the Vehicle,
that a wheel equivalent to a fly wheel can be attached to the axle of a rear driver
or safety Cycle, or to the axle of the driving gear of a Tricycle, or on the main axle
of the bearing wheels, which in the case of a Tricycle, one fly wheel would be arranged
on each side between the main frame and the ordinary bearing wheels.

declare the nature of the said invention and in what manner the same is to

For the purpose of the second part of this invention we attach weights or blocks
adjustablo on or to the travelling wheels, such as on parallel spokes, or to the
driver wheel of a Bicycle, Tricycle or like vehicle, the weight or block being near
to the periphery and at such parts that the pressure on the pedals shall impart
an additional thrust to the weight, so that as the foot of the rider is stretching in
following the pedal. but not exerting a pressure, the weight is utilized for carrying
the wheel round until the rider's foot gives the necessary pressure for the next onward
thrust..
According to the third part of the invention we so make the frame of the
vehicle that a. wheel equivalent to the fly wheel can be attached to the axle of a
rear driver or safety cycle. or to the axle of the driving, gear of a Tricycle, or on
the main axle of the bearing wheels: which in, the case of a Tricycle, one fly
wheel would be arranged on each side between the main frame and the ordinary
bearing wheels..
The invention is carried into practice as follows:-
Figure 1. of. the annexed drawings is an off. side. and Figure 2 a near side
elevation of a Safety Rear Driver Bicycle with the first improvement applied thereto.
A, A, is the lower. base. B the extension. C the small wheel. D. the fly wheel
on the same axle as. C and. receives rotation from the: chain, E, which partakes of
motion from the pedals F, F, the chain. E being of such a. length that it is in gear
with pinion C, chain wheel G.and driving wheel. H.
This part of, the invention is applicable. to. Tricycles and similar vehicles worked by
hand or foot power.
Figure, 3 represents a rear driver Bicycle, to the driving, wheel H of, which we
attach a. block or weight I. preferably. between two of the spokes which are made
parallel for adjusting, the weight. nearer to or farther from the centre the weight
being, provided with a clip screw for fixing it.at the desired distance between the hub
and the rim.
Figure 4 represents a rear driver Bicycle with the axle of the driving gear with
a fly wheel D attached either in halves and bolted to the axle or slipped on to
the axle before the pedals F Fare put into their places. The fly wheel D in this
instance, as also that shewn in. Figure 6 is fitted.close up to the chain wheel G on
said axle and between the fork J so as not to interfere with a persons legs while
working the pedals F.
Figure 5 is.a view of a Tricycle provided with parallel spokes and weights I, I,
on the driving wheels H, H, in a. corresponding manner to that described with
reference to Figure 3.
Figures 7 and 8 shew side and back elevations of a Tricycle to the main axle K of
which two fly wheels D, D, are fitted one being on each side between the wheels
and the main frame L which main frame is made narrower, than usual to permit of
the fly wheels D, D, being fitted on the axle.
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 :-
1. Arranging with the driving gear of a Bicycle or Tricycle an additional shaft,
carrying fly wheel and pinion, substantially as shown for the purpose set forth.

page_text: 2. Fitting to the lower brace or braces of a Bicycle or Tricycle an extension
for supporting an axle on which a chain' pinion and a fly wheel are mounted said
chain wheel being driven from the pedal gear at a greater speed than that of
the pedals themselves, as described and as shown at Figures 1 and 2 of the annexed
drawings.
3. In combination with a wheel or wheels of a Bicycle, Tricycle, or like vehicle,
a weight and parallel spokes for the adjustment of the weight thereon, as shewn at
Figures 3 and 5 of the annexed drawings for the purpose described.
4. In combination with the driving axle of a rear driver Bicycle or Tricycle, a
fly wheel as shewn at Figures 4 and 6 of the annexed drawings for the purpose
described.
5. Arranging two fly wheels on the driving axle of a Tricycle of the construction
shewn in Figures 7 and 8 of the annexed drawings as and for the purpose described.
