PROVISIONAL SPECIFICATION.
Improvements in Cycles, Velocipedes, and such like Machines..
JOHN HENRY MUMFORD 93 High Street West Cowes Isle of Wight Refresh-
ment House Keeper do hereby declare the nature of this invention to be as
follows: :-
This my invention relates to certain now and useful improvements in cycles
velocipedes and all such like, propelled by manual power.
The object of my invention is to provide increased driving power to such
machines the same being effected according to my improvement by means of
applying hand power in conjunction when so desired with the ordinary foot treadle
power.
I will describe this my invention as applied to a rear driving tricycle.
In making a handlebar of a tricycle according to one form of my invention, I
construct the same in two parts, suitably connected together, one part the front is
connected to the steering tube or bar in the usual manner and it does the ordinary
duty, and is similar in shape and arrangement to an ordinary handlebar.
The other part which I will call the inner handlebar is provided with two cranks
(dips) formed out or attached to it, the bar extends across the tricycle in a direction
approximately parallel to, and on a level with the front handlebar to which it is
attached, but at the connections it works in bearings thereby allowing it to freely
revolve when the machine is in motion.
On the crank spindle which I call the inner handlebar, I fit a driving wheel
which I connect by chain to another wheel which is fitted on the axle of front
steering wheel.
The rider can increase the speed and power exerted on his machine by grasping
the cranks and causing the inner handlebar to revolve, therefore the machine can
be driven by a combination if desired of hand and foot treadle power.
It may be convenient to make the handlebar in one piece with two crank dips,
the bar to work with bearings in the centre of handlebar fitted in head of tube
to steering wheel being connected by chain-gearing the same as the inner handle-
bar, and does the duty same (as inner handlebar).
This machine can be both steered and driven by the hand cranks only, or by the
foot treadles only as it can be put in and out of gear at riders will without stopping
machine.
The front part of handlebar is sufficiently bent to allow the cranks on spindle and
driving wheel to work clear and freely when the spindle is in motion.

page_text: 1, JOHN HENRY MUMFORD of 93 High Street, West Cowes, in the Isle of
Wight, Refreshment House Keeper 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 invention is to increase the driving power in the mechanism
of cycles and such like machines..
In carrying out my invention either applied to tricycles, bicycles or other
velocipede or machine of like kind 1 provide means for utilizing hand power for use
separately or in conjunction with the ordinary foot treadle power.
I have herein described my invention as applied to a rear driving tricycle but
the application thereof to other form of machine will be obvious to any practical
mechanic.
Although the ordinary handle steering bar of a tricycle may be retained and my
cranked driving axis be made supplemental thereto I have not found the said
arrangement so convenient as that hereinafter described wherein the cranked
driving axis is made to serve as the hand driving and steering means that is to say
on the crank spindle which constitutes the handle bar I fit a driving wheel which
I connect by chain, band or other transmitting means to a driven wheel mounted on
the axis of the front wheel of the machine and which driven wheel is capable of
being put into or out of gear with said wheel as desired to utilise or not the hand
power, by means of a clutch of ordinary well known or convenient construction
actuated by handle or pedal leverage as preferred.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view and Figure 2 a front view of so much of a velocipede
as is necessary in order to elucidate the application of my invention. a is the handle
bar of which a', a are.the ordinary handles to be grasped one or both in ordinary
fashion for steering as required. are supplemental handles mounted in the
cranks, formed to the handle bar a and adapted to be grasped either or both by
the rider when the hand driving power is to be utilised.
C
This bar a is mounted to rotate in bearings c', e' on the upper part c² of the
* tube "
or head of the machine and on the bar is rigidly mounted a gear wheel
around which is laid a chain e which also passes around and gears with the gear
wheel carried by the axis d of the front wheel e. A clutch which may be of
ordinary or convenient construction, when moved towards or from the wheel c³
engages or disengages the said wheel with the axis & and causes the said wheel and
axis to rotate in unison. e are the prongs of the fork carrying the front wheel.
g is a portion of a back bone or connection to the other wheel or wheels and
parts of the machine not shewn, such being of any ordinary or convenient con-
struction is a lever centred at 2 for operating the clutch fand f³ is a guide way
in which this handle slides being two notches in which the lever handle is
lodged to keep it in position to engage or disengage the clutch f.
In operation the rider to employ the hand driving gearing to operate the front
wheel takes hold of both or either of the crank handles and turning thereby
the axis a rotates the wheel 3 and thereby moves the chain and thereby
rotates the wheel c which being in clutch connection with the hub of the wheel e
rotates it.
One hand of the rider may retain hold of a handle a¹ whilst the other drives a
crank handle b¹ especially during learning.

page_text: 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 bicycle, tricycle, or other cycle, or such like machine, a rotary handle bar
provided with a pair of oppositely cranked handles and pair of axial steering handles
and operating a wheel, or part, adapted to drive by chain, or equivalent means,
another wheel, or part, capable of being engaged with or disengaged from the axis
of the bearing, or driven wheel or wheel of the machine as set forth and illustrated
in the accompanying drawings.
