Office of the Commissioners of Patents on the 29th July 1882.
JOHN PETER DALBY of Leeds in the County of York
TRICYCLES BICYCLES AND OTHER SIMILAR VEHICLES,"
"IMPROVEMENTS IN
My improvements consist in an arrangement whereby I am enabled to actuate
tricycles either by hand and foot combined or separately thus making the ascent
of hills more easy.
These improvements have further reference to apparatus for
steering the same.
I apply two pairs of levers placed in such a position on each side of the operator
that one lever of each pair which is in the form of a treadle may be worked by the
foot and the other provided with a handle may be used by the hand, and both
simultaneously when required and I connect the levers to the cranks in such a
manner that the treadle must be moved downwards by the foot whilst the handle
is pulled upwards by the hand. By this arrangement the operator is enabled to
apply more force in the working of the tricycle than hitherto.
Instead of a hand lever a chain in connection with the cranks or in combination
with a ratchet or friction arrangement may when preferred be employed.
I also provide an arrangement whereby the hand movement may remain
stationary whilst the treadle motion is being worked.
For the purpose of steering I provide two arms in such a position on the machine
that they can be moved by the elbows of the occupant of the vehicle. These arins
are connected with the steering wheel carriage by a rod and lever so that by a
movement of the elbow or elbows the required turn or direction can be given to
the guiding or steering wheel. In order to give steadiness and support to the
steering wheel of the vehicle I attach an arm or arms to the fork at a suitable
angle therefrom.
A runner is mounted on the ends of the arms resting against a curved plate
attached to the framework of the machine working backwards and forwards in
contact therewith in whatever direction the steering wheel is turned.
The framework of the machine is of simple construction.

"IMPROVEMENTS IN
My Improvements consist in an arrangement whereby I am enabled to actuate

For the purpose of steering I provide two arms in such a position on the machine
that they can be moved by the elbows of the occupant of the vehicle. These arms
are connected with the steering wheel of the carriage by a rod and lever so that by
a movement of the elbow or elbows the required turn or direction can be given to
the guiding or steering wheel. In order to give steadiness and support to the
steering wheel of the vehicle I attach an arm or arms to the fork at a suitable

A runner is mounted on the ends of the arms resting against a curved plate
attached to the framework of the machine working backwards and forwards in
contact therewith in whatever direction the steering wheel is turned
The framework of the machine is of simple construction
And in order that my Invention may be the more completely understood
reference is given to the accompanying drawings and to the letters and marks
thereon.
DESCRIPTION OF DRAWINGS
Fig 1 is a back elevation Fig 2 a sectional elevation on A B Fig 3 Fig 3 a
plan looking at the top and Figs and 5 are respectively side elevation and plan
of details to be hereafter described

page_text: which are of ordinary construction. The treadle levers e and e¹ are also mounted
on the shafts h and i respectively and are secured thereto by pins keys or other
convenient means.
The driving wheels bb are mounted on the shaft n such shaft being provided
with the cranks o and p. These cranks o and p are coupled to the treadle levers e
and e by the connecting rods r and 8. It will be readily understood that the
required rotary motion may be imparted to the driving wheels bb of the tricycle
by the rider imparting the ordinary treadle movement to the levers e and e¹. In
order when required to bring the hand levers d and d' into gear with their respective
shafts h and I key or otherwise fasten on the shafts h and i the short levers t
and u between the forked ends of the levers d and d¹
When the hand movement is not required and motion is imparted to the
machine through the treadle levers e and e¹ only, the short levers t and u are free
to move with the shafts h and i leaving the hand levers d and d stationary, but
when the rider wishes to use the hand movement in combination with that of the
treadle and in order for this purpose to bring the hand levers d and d¹ into gear
with the shafts h and i I provide the hinged sliding pieces which are moved
forward under the ends of the short levers t and u by the rider through the
vertical rods w bell cranks x and rods y. The sliding pieces are hinged so as to
allow the short levers t and u to pass upwards into the position shewn in the
drawings. It will be readily seen that by this arrangement the movement of the
hand levers d and d¹ is so connected with that of the treadle levers e and e¹ as to
assist in the moving of the machine and in such a manner that as the right (or left)
hand treadle levers are moved downwards their respective hand levers are moved
upwards and that by such an arrangement the rider is able to apply more force in
the working of the tricycle than hitherto
When my Improvements are applied to such tricycles as are actuated by a
revolving pedal shaft having chains or spur gearing for transmitting motion to the
driving axle I mount two discs in a suitable position on the pedal shaft having a
rachet or frictional driving arrangement which is actuated through chains, straps
or their equivalents in connection with the handles. g.
In order to give steadiness and support to the steering wheel c of the tricycle I
attach the arms or mud-guard stays 1 to the steering wheel fork 2 by any ordinary
means at 3. At the outer ends of the arms or mud-guard stays 1 are mounted so
as to work freely the runners 4. These are in contact with the curved plate 5
attached to the framework a and remain in contact in whatever direction the
steering wheel is turned. This arrangement for steadying and supporting the
steering wheel is also applicable to bicycles and other similar vehicles.
For the purpose of steering I provide the arms 6 with pads or plates 7. The
arms 6 are fixed on the upper ends of the inclined shafts 8 which are mounted in
bearings 9 and 10 attached to the framework of the machine. At the lower end
of the inclined shafts 8 are fixed the levers 11, the free ends of which are attached
to the runner arms or mud-guard stays 1 by means of chains ropes or their
equivalents. By this arrangement the occupant of the tricycle may move the
steering wheel in any required direction by his arms or elbows, and so guide the
machine.
Having now described the nature of my said Invention and shewn by the aid of
drawings how the same may be carried into practice I would have it understood
that I do not limit myself to the details and configuration of the parts described
and shewn as the same may be varied or modified without departing from the nature
of my said Invention but what I do claim is :
Firstly The means employed for combining the treadle movement in tricycles
bicycles and other similar vehicles with the hand movement as shewn in the
drawings also in such vehicles as are actuated by revolving pedal and chain spur
rachet or frictional gearing substantially as and for the purposes herein set forth
Secondly. The arrangement and application of the hand levers d and d' and the
parts connected therewith and the means employed for throwing them in and

page_text: out of gear with the treadle levers e. and e¹ substantially as and for the purposes
herein set forth
Thirdly The arrangement construction and application of the means employed
for giving steadiness and support to the steering wheel of tricycles bicycles and
other similar vehicles substantially as and for the purposes herein set forth.
Fourthly. The general arrangement and combination of the various parts
forming the tricycle shown in the drawings and mere modifications of the same
substantially as herein set forth
In Witness whereof I the said John Peter Dalby have hereunto set my
hand and seal this nineteenth day of January in the year of Our Lord one
thousand eight hundred and eighty three.
