page_text: HENRY CHARLES TUCKER Surveyor 44 Warwick Road Banbury Oxon do hereby
declare the nature of this invention to be as follows:-
:―
My invention consists in the arrangement of a wheel and attachments to in such
a way as to enable a person to ride a travelling wheel on the road without the aid of
a second wheel.
Perpendicular to the centre of the wheel a frame can be supported by the wheel
axle and to the frame near the ground a step or footrest is supported by the frame so
that it can be adjusted to suit the height of the rider.
Under the step there is a rubber roller that touches the ground only when the
rider mounts the machine.
But this roller also serves to keep the machine upright when at rest.
To the framework below the axle is attached a wheel that revolves to carry a
chain which is in connection with a smaller but similar description wheel fixed to the
travelling wheel so that by means of cranks which can be fixed in front of the rider
while he is in a standing position to operate on the handles or cranks.
Thero is connecting rods between the cranks and the chain wheel so that when the
cranks are set in motion by hand, the machine easily moves as a road conveyance.
The steering is effected by the weight of the rider being thrown on to either side
as the machine advances, which is more particularly described and shown by tho
accompanying Drawings Figured from 1 to 6.
Fig. 1. is the side view of the machine. a is the travelling wheel-b. is the framo
supported by the axle of the travelling wheel. c. is a step or foot-rest which can be
raised or lowered to suit the comfort of the rider. On the upper side of the step
rubber bars d. can be fixed to act as a spring upon which the rider can stand-and
under the step is a rubber roller e. that does not touch the ground except when the
rider steps on to the machine to mount it. These rollers also serve to keep the
machine standing upright when at rest. The crank wheel F. is to carry a chain on
the rim, the same chain also passes over the smaller wheel G. which is fixed to the

page_text: travelling wheel in such a way that they both move together when the cranks F are
set in motion as there is a connecting rod 1. between the chain wheel and the first
motion cranks so that by hand power the machine is propelled.

sponding to the reference letters as stated in Figure 1.

page_text: HENRY CHARLES TUCKER 44 Warwick Road Banbury Oxon Surveyor, 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 nature of my invention consists in the method of applying a travelling or
driving wheel, having attachments thereto in such a way as to enable a person to
ride by the means of one wheel, on the road as a unicycle conveyance, not requiring
the aid of another or second wheel.
To the centre of the driving wheel a frame is supported by the wheel axle, which
is made fast to the frame so that the wheel may revolve while the frame and axle is
fixed to each other.
To the lower part of the frame there is a step or standing place attached in such a
manner as to be adjustable up or down according to the size of the wheel, and to suit
the height of the rider when with one leg on each side of the wheel stands on the
step to ride.
Below the step attached to the frame there is a break-bar, and there may be either
a roller or a knob at the end. It touches the ground only when the rider mounts
the machine, or when it is at rest, so that it will stand upright supported by the
break bars bearing on the ground.
The same break-bars act as a break when the rollers, or knobs, come in contact
with the ground which is effected by the weight of the rider, (at his will) being
thrown a little backwards it lessens the speed when descending an incline.
The steering is actuated by the weight of the rider bearing more or less to the
right, or left, on the steps while the machine advances.
To the upper part of the frame in position in front of the rider the first power
motion cranks, or handles, are placed so that by means of a wheel and endless chain
which passes round a smaller but similar wheel firmly fixed to, or it may form part
of the driving wheel, so that when the cranks or handles are set in motion the
driving wheel makes its propelling revolutions as a conveyance, while the rider
stands on the steps, as hereafter more particularly described and shown by the
accompanying Drawings Figures 1. and 2.
Figure 1. is the side view of the machine. A is the travelling or driving wheel,
which makes its revolutions on the axle to which the frame B. is firmly fixed or
keyed.
To the lower part of the frame B. there is an arrangement that forms a step or
standing place C. which is so constructed that it can be adjusted up or down according
to the size of the wheel A, and to suit the height of the rider.
Below the step there is a breakbar E, one end of the bar is firmly attached
to the frame B. the other end may be as a roller, or a knob, the bar must be of
sufficient length so that the riders weight when thrown back a little will cause the
knob or roller to trail on the ground forming a break to lessen speed.

page_text: The same bar also serves to keep the machine upright when at rest also when the
rider mounts the machine.
To the upper part of the frame B. in front of the rider the first power motion wheel
-and-cranks Fare placed, the endless chain passes over this wheel also round a smaller
wheel of a similar description which is firmly attached to the driving wheel A. so
that by the means of the cranks, or handles, the first motion is actuated by the rider
while in a standing position on the steps.
Figure 2. is enlarged scale drawing to show the front view of the Machine, the
description corresponds with Figure 1.
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,
First my absolute right to employ, make use of, or apply ono travelling or driving
wheel so as to form part of a Vehicle that a person can ride it as a one wheel
conveyance or unicycle, as herein substantially described in the foregoing Specifi-
cation.
2nd claim is the step or standing place upon which the rider stands, as herein
substantially described in the foregoing Specification.
3rd claim is the break-bar with roller or knob end as serving combined purposes,
as herein substantially described in the foregoing Specification.
4th claim is the position and method of supporting the first power motion
cranks or handles actuated by hand power by the rider while in a standing position
on the steps, as herein substantially described in the foregoing Specification.
5th claim is the combination of the foregoing claims operating together by that
means constituting a novelty one wheel conveyance as a unicycle machine of public
utility.
