page_text: by depressing the pedal j2 on the left-side of the cycle and lifting the hand lever k¹
of the driving mechanism j¹ m¹ or provided on the right side of the cycle, the
toothed ring or rack c is caused to perform a quarter of a revolution and the parts of
the mechanism to move into the positions indicated in dotted lines. Then, by
depressing the pedal 7 of the driving gear on the right, and raising the hand
lever ² of the driving gear on the left, the toothed ring c is made to complete a
further quarter of a revolution and the left hand driving mechanism j², m², o² is
brought back to the same position as that which the right-hand driving mechanism
had at first occupied; and conversely the right-hand driving mechanism will thereby
be made to resume that position which the left-hand driving mechanism had
occupied at the start.
The toothed ring e engages with the toothed wheel b, which thereupon imparts
motion to the front wheel a of the cycle. The rider must therefore alternately
depress the pedal on one side, while raising the lever on the other, and vice versa.
He leans back on the rest with which the front fork e is provided for the purpose
and which mainly consists of a curved wire frame (Figure 6) covered with leather.
This, in a literal sense, is not a seat, however, as the weight of the body is transferred
to the pedals and the hand levers.
For the convenience of the rider the pedals should be adjustable so as to
accommodate his height. For this purpose each pedal is mounted on a swinging
rod m or such pedal may be secured directly to the cylinder or casing d as shown in
Figure 7.
It may be necessary to put the pedals out of gear so that they may remain
inoperative, say, whilst the machine is travelling down-hill. This result may be
attained by means of any well known construction; for instance, by mounting the
pedals on a separate toothed wheel coupled with the cylinder d through suitable
clutches. This construction, being obvious, it is not shown in the drawings.
Finally, it may be remarked that the toothed ring c may be mounted in the fork e
by any other suitable means.
The machine is steered by the levers & which are equivalent to the ordinary handle
bar. Such levers may, however, slide in guides, so that the extent (or amplitude) of
their movements may be adjusted (Figure 9).
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. A cycle having means for driving it by hand and foot comprising pedals j and
hand levers k, an internally toothed ring c mounted in the fork e of the driving
wheel, a toothed wheel mounted upon the axle of such driving wheel and a back
rest serving as a means of supporting the rider substantially as set forth.
2. In a cycle, a driving gear comprising a toothed ring c formed with, or connected
to, a thin-walled cylinder or casing d, rotatably mounted within an annular
enlargement of a fork e substantially as described and shown in the drawings..
3. In a cycle such as referred to in the preceding claims the combination, in the
driving gear, of pedals mounted either directly upon the casing d or upon swinging
rods m substantially as described.
