do hereby declare the nature of this invention to be as follows :-
:-
This invention relates to an improved machine for two riders sitting side by side
sociable fashion, having a single driving wheel, and two steering wheels.
Each side of the driving wheel is mounted a saddle or seat for each rider, who has a
pedal-shaft driving the main axle, by means of chains or other suitable gearing.
The driving wheel axle running in two bearings mounted on the framework each
side of the driving wheel, at the same time carrying the seat or saddle supports and
pedal shafts; at the front end of the sido frames is a crossbar on which the two steering
In
wheels are mounted, each steering wheel working in a steering head or socket.
front of each saddle is a tee handle bar carried downwards to the crossbar, central
with each pedal shaft bracket.
The two steering wheels are connected by a coupling rod, which is attached by a
lever from the steering handle, so that both wheels are steered right and left by turning
the handle bar in the same direction.

Engineers 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 relates to an improved machine for two riders sitting side by side
sociable fashion having a single driving wheel and two steering wheels. On each side
of the driving wheel is mounted a saddle for each rider who has a pedal shaft driving
the main axle by means of chain or other suitable gearing. The driving wheel axle
running in two bearings, is mounted on the framework on each side of the driving
wheel, at the same time carrying the seat or saddle supports and pedal shafts; at the
front end of the side frames is a crossbar on which the two steering wheels
are mounted each steering wheel working in a steering head or socket.
front of each saddle is a Tee handle bar carried downwards to the crossbar central
with each pedal bracket. The two steering wheels are connected by a coupling rod
which is attached by a lever from one steering handle so that both wheels are steered
right and left by turning the handle bar in the same direction.
In
Figs. 1 and 2. shew a side view and plan of the machine with the steering wheels in
the same plane as the saddles and driving gear. The driving wheel 1 and axle 2
run in the bearings 3 and 4 each being carried by the side frames 5 and 5¹ on
each side of, the driving wheel 1. The steering wheels 7 and 8 are carried in
the forks 9 and 9 hinged to the frame; and are connected together by the steering
rod 10 and levers 10¹ thus coupling the handle bars 11 and 11' and the steering
wheels 7 and 8 together.
Two saddles or seat supports 12 and 121 are mounted on the side frames 5 and 5¹:
the power of the two riders being transmitted to the driving wheel axle 2 by
means of the pedal shafts 13 and 131; cranks 14, and the chain gears, 15 and 151.
'It may be sometimes preferred that the steering should be under the control of one
rider; this may be done by disconnecting the steering lever from the handle bar 11
and 111.
Figs. 3 and 4 shew a side view and plan of a machine with the wheel base of
the steering wheels 1 and 2 wider than the saddles 3 and 4 and driving gear 5 ;
the steering wheels 1 and 2 are mounted on pins hinged to the crossbar 6 and 6¹
which ties the two side frames 7 and 7' together.
The handle bars 8 and 8¹ are each provided with a lever 11 and 11¹ and are
coupled together by the coupling rod 13 (shewn in dotted lines) the two steering
wheels 1 and 2 are coupled together by the coupling rod 10 and levers 9 and 9¹
(shewn in dotted lines) the coupling rods 10 and 13 are coupled together by
the link or rod 12 shewn in dotted lines.
One or both handles can be used for steering. In the case when one handle is
used the lever 11 or 111 can be disconnected from the handle bar and the handle
bar which is not used for steering purposes is made a fixture of.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1. A Velocipede consisting of one rear driving wheel propelled by two riders
seated, one on each side of the same, and steered by means of two loose wheels,
each of which being pivoted by means of a suitable head or hinge placed either
above or by the side of the same; these said heads or hinges being mounted on a
cross arm forming a rigid part of the framework.
2. A Velocipede with a single driving wheel furnished with seats and driving
gear for two riders, and with two steering wheels directed by one rider or by
both riders, substantially as described.
