We, ISAAC WATTS BOOTHROYD, of 15 Circus Street, Greenwich, in the County
of Kent, Manager, and PHILIPP LOUIS CHARLES FREDERICK RENOUF, of 46 Roland
Gardens, in the County of Middlesex, Student of the Inner Temple, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to that class of velocipede in which a large wheel is driven
and a pair of small wheels steer, in such a way that when a curve is described the
axes of the three wheels radiate towards one common centre.
In this case we preferably put the steering head and centres below the axes of the
steering wheels so as to leave as great a space as possible free for mounting and
dismounting or for carrying luggage, a child or invalid or for mounting one or more
additional seat or seats for other riders.
In the latter case the additional driving gear is coupled with the main driving
wheel either directly or by means of the driving gear of the principal rider which
may be of the endless chain or like transmission type, lever and connecting rod or
lever and clutch or lever and rotary action. In this latter case we prefer to employ
flexible wire, running over pulleys, consisting either of a single, or, several pieces of
straight wire either separate or bound together by transverse coiling and in case of
small drums we may coil the wire once round.
When we employ this cycle as a carrier or tandem the seat of the rider or parcel
carrier may be fixed either to the main frame so as to remain in a line with the same
under all circumstances or else may be mounted in such a way as to turn together
with the steering wheels when the latter are describing curves.

page_text: We ISAAC WATTS BOOTHROYD of 15 Circus Street Greenwich in the County of
Kent Manager and PHILIPP LOUIS CHARLES FREDERICK RENOUF of 46 Roland
Gardens in the County of Middlesex, Student of the Inner Temple 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 :-
We construct our improved velocipede by joining two parts of the framework by a
head or hinge; one part of the frame being supported by two steering wheels and the
other supported by the driving wheel carrying the seat and handles of the rider.
Motion is communicated by means of reciprocating levers and connecting rods
which pull a pair of cranks attached either directly to the driving wheel or to a
multiplying gear.
The levers may be provided with a second set of pedals for a second rider, in which
case the connecting rods should be strong enough to push as well as pull the driving
cranks.
The steering gear is preferably placed under the seat pillar so as to leave the whole
front of the machine open, so as to be rendered safe and easily rideable by a female.
Referring to the drawings, A (Figures 1. 2 and 3) is an axle or cross piece
carrying two wheels and swivelling in the steering head B; C (Figures 1 and 3) are
pedal levers actuating connecting rods D which pull the cranks E; fixed to the
driving wheel axis.
Through the upright part of the main frame which carries the seat on Figure 1 a
steering rod is passed, fixed at one end to the handles F and at the lower end to a
disc; this disc is connected to a similar disc fixed to the steering head by means of a
flexible band.
Figure 4 shows the levers as constructed for two pairs of pedals; they are cranked
in such a way that the right front pedal and the left back pedal form one rigid piece,
so that both riders move their right and left feet in unison with each other and
maintain an even sway when riding.
The seat of the front rider is shown on Figure 3, attached to the front or steering
part of the frame so that the steering action of the rear rider carries the body of the
front rider to be swayed according to the direction taken; but the seat may if desired
be fixed to the rear part of the frame, though this is not so advantageous.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is:
1. The combination of a lever action velocipede in which the steering action is
provided by two wheels mounted on a cross piece or arms radiating from one steering
centre, and connecting rods pulling at cranks fixed either to a driving wheel directly
or to a multiplying gear.

page_text: 2. Steering by means of a handle bar fixed to a rod placed in vertical position and
connected with the steering head by means of the flexible band as described and for
the purpose described.
3. The pedal lever capable of being actuated by two riders substantially as
described.
4. A tandem bicycle in which both riders, looking in the direction in which they
are travelling propel the machine by means of reciprocating levers.
5. The levers carrying two pairs of pedals and constructed substantially as
described.
