Improvements in the Construction of Tricycles and other
Velocipedes
I JOHN CHIPPINDALL of Cheetham Hill Manchester in the County of Lancaster
Clerk in Holy Orders do hereby declare the nature of this invention to be as
follows
-
This invention is applicable principally to that class of tricycles of the front
steering type which are steered by means of a cross handle bar pivoted at the
centre, but it is also applicable to other forms of velocipedes fitted with i cross steering
handle bar commonly known as a bicycle handle bar
"
The object of the invention is to enable the rider to propel the machine by either the
feet or the hands at will or by both at the same time when required, is for instance
when ascending steep gridients
The cross handle bar (inste id of being attached direct to the head of the front wheel
fork, as hitherto done) is attached to a vertical rod or shaft-which is mounted in fixed
bearings carried by the frame so that it can revolve, and it is geared to the sloping
shaft which is fixed to or forms part of the front wheel fork in the following
manner
A toothed pinion is fixed on the sud sloping shaft and a toothed quidrant is fixed
on the above named vertical steering rod or shaft Between these two is a double
toothed quadrant lever in gear with both, and this quadrant lever turn upon a centre
which is nearer to the vertical steering rod than to the sloping shaft of the front fork
so that the front half of the double quadrant lever has a much longer radius than the
rear half, and hence it requires only a very slight vibratory movement of the handle
bar to give a quarter of a turn to the sloping steering shaft
The handle bar is so mounted that it can also oscillate or partially revolve and it is
fitted with two handles mounted loosely for use in the ordinary manner when driving
the machine by the feet only
And in order to enable the hands of the rider to be utilized for driving instead of,
or as well as, the feet when required, the handle bar is prolonged beyond the handleg

page_text: and has attached to each end or prolongation hand lever (projecting backwards) by
means of which it can be rocked or partially revolved, or the ends of the handle bar
may be bent backwards so as to form levers
Between the ordinary handles and the central pivot, the handle bar is also fitted
with two short levers (projecting forwards) and the end of each of the latter is jointed to
the upper end of a connecting rod, the lower end of which is similarly jointed to one
of the cranks at about midway between the pedal and the crank shaft, and thus it
will be evident that by releasing the ordinary handles and grasping the lever
handles the rider can apply the force of his hands to the driving of the crank
shaft instead of, or in addition to, that of his feet upon the pedals, and thus he
can drive the machine with either hands or feet at will, and on a heavy rond, or
when ascending a steep gradient he can utilize the muscles of both arms and legs and
thus gain a considerable increase of power, at the same time that by the lever handles
he has perfect control over the steering
It will be observed that the lever handles are so arranged that the rider pulls
them up alternately on each side in opposition to the downward thrust of his
foot on the pedal at the same side, and thus the maximum of power is obtained
This combination of hand with foot power, while it considerably increases the
ability of the rider to ascend steep gradients, to a great extent diminishes fatigue and
at the same time obviates the necessity of either hand or foot brake, as the machine
can be immediately stopped either by combined back pedalhing and arrest of the notion
of the hand-levers, or by the adoption of either of these methods

I JOHN CHIPPINDALL of Cheetham Hill Manchester in the County of Lancaster
Clerk in Holy Orders 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 is applicable principally to that class of tricycles of the front steering
type which are steered by means of a cross handle bar pivotted at the centre, but it is
also applicable to other forms of velocipedes fitted with a cross steering handle bar
commonly known as "bicycle handle bar "
The object of the invention is to enable the rider to propel the machine by either
the feet or the hands at will or by both at the same time, when required, as for instance
when ascending steep gradients
The nature of my said invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference to the
annexed sheet of drawings and the following explanation thereof
Fig 1 on the drawings is a side elevation of a tricycle made according to my
improvements one of the driving wheels being removed in order to show the
working parts more clearly, and Figs 2 6 and 4 are views of detached portions thereof
hereinafter more particularly referred to
a is the main frame of the machine 6 the main axle, c one of the driving wheels-
d the front wheel and e the inclined steering fork
The cross handle barf (instead of being attached direct to the head of the front
wheel fork e as hitherto done) is attached to a vertical rod or shaft g which is mounted
in fixed bearings h carried by the frame a so that it can revolve, and it is geared
to the sloping shaft e¹ which is fixed to or forms part of the front wheel fork e in
the following manner
A toothed pinion (see also detached plan view Fig 2) is fixed on the said
sloping shaft and a toothed quadrant, is fixed on the vertical steering rod or
shaft g
Between these two is a double toothed quadrant lever in gear with both, and this
quadrant lever turns upon a centre which is nearer to the vertical steering rod g
than to the sloping shaft e¹ of the front fork so that the front half of the double
quadrant leverk has a much longer radius, than the rear half, and hence it requires
only a very slight vibratory movement of the handle bar f to give a quarter of a turn
to the sloping steering shaft e¹
The handle bar fis so mounted that it can also oscillate or partly revolve in the
boss g' at the head of the vertical steering rod g, and it is fitted with two handles or
rundles m mounted loosely for use in the ordinary manner when driving the machine
by the feet only

page_text: And in order to enable the hands of the rider to be utilized for ariving instead of,
or as well as the feet when required, the handle bar is prolonged beyond the loose
handles m and has attached to each end or prolongation a hand lever n (projecting
backwards) by means of which it can be rocked or partially revolved, or the ends of
the handle bar may be bent backward so as to form levers I prefer however the
former and to connect these levers to the handle bar (as shown detached in plan view
at Fig 3) by means of a butt Joint which will allow of their being bent slightly
inwards so as to keep the hands clear of the wheels in turning without interfering with
their rigidity in a vertical direction
Between the ordinary handles m and the central pivot, the handle bar f is also
fitted with two shorter levers o (projecting forwards) and to the end of each of the
latter is jointed the upper end of a connecting rod p, the lower end of which is
Similarly jointed to one of the cranks q at about midway between the pedal r and the
crank shafts (see also detached front view Fig 4) and thus it will be evident that
by releasing the ordinary handles m and grisping the lever handles n the 11der can
apply the force of his hinds to the driving of the crank shaft s instead of or in addition
to that of his feet upon the pedals and thus he can drive the machine with either
hands or feet at will, and on a heavy road or when ascending a steep gradient he can
utilize the muscles of both arms and legs and thus gain a considerable increase of
power, at the same time that by the lever handles n he has perfect control over
the steering
It will be observed that the lever handles n and their adjuncts are so arranged that
the rider pulls them up alternately on each side in opposition to the downward thrust
of his foot on the pedal at the same side, and thus the maximum of power is
obtained
This combination of hand with foot power, while it considerably increases the
ability of the rider to ascend steep gradients, to great extent diminishes fatigue and
at the same time obviates in a great measure the necessity for the application of either
hand or foot brake as the machine can be quickly stopped either by combined back'
pedalling and arrest of the motion of the levers or by the adoption of either of these
methods
V
I prefer however to adapt the usual band brake and levers wand x (see Figs 1
and 3) to my velocipede, as the too sudden reversal of the driving might strain the
machine
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 18 -
The combination in tricycles or other velocipedes of the hand and foot motions con-
structed and arranged substantially as hereinbefore described and illustrated by the
drawings annexed whereby either motion may be used by itself or both combined as
may be found preferable
