Our invention relates to improvements in connection with the propulsion of
life and other boats, the object being to obtain such propulsion by the use of
sorew propellers rotated by the pedalling movement of the workers' feet. In
carrying our invention into effect, we proceed in or in about the following
manner, premising that although only two workers or operators will be, mentioned
in 'this specification, it is not intended to limit the number to two. The workers
sit side by side on saddles supported in, suitable standards The saddles are
similar to those used on cycles, and handle bars may be provided for the purpose
of enabling the workers to bring more power into use and also if desired, to be
attached to cords,
ds or the like by which the rudder can be manipulated.., The
saddles are so arranged that the workers do not face the same way, one looking
forward, and the other to the rear. Supported in suitable bearings fixed to the
bottom of the boat, is a crank axle (one for each rider) supplied with pedals. Each
pedal revolves in a vertical plane, parallel with one passing through the axis
of the boat
boat. On the inner end of each crank spindle, is a bevel
wheel each of which gear
gears into an intermediate bevel wheel running
at right angles to the two bevel wheels. On the same spindle as the intermediate
bevel wheel, is a plain, spur wheel gearing (below) into a spur pinion which in
turn gears in a pinion threaded on the propeller shaft. The propeller shaft is
supported in suitable plain and thrust bearings. At one end of the, shaft is a
screw propeller, and on the same shaft may be a balance wheel. The working
parts may be cased in to protect them from damage.

On the workers rotating the crank shafts by pedalling, the bevel wheels thereon
will rotate the intermediate wheel, as the workers operate their respective cranks,
in opposite directions, which would not be the case were each worker facing the
same way. The intermediate wheel will cause the plain spur wheel on its axle
to also rotate and this will revolve the pinions and the shaft and propeller.. Any
suitable steering arrangement may be employed, either worked from the handle bars
or separately therefrom.

Improvements in connection with the Propulsion of Life and other
Boats.
We FREDERICK EDWARD WYATT and WILLIAM HENRY WYATT of No. 4 Nile
Street, St. John's, London, S.E., Grocers, 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:-
b
Our invention relates to improvements in connection with the propulsion of
life and other boats, the object being to obtain such propulsion by the use of
screw propellers rotated by gearing operated by the pedalling action of the workers'
feet. In carrying our, invention into effect we proceed in or in about the following
manner making reference to the accompanying sheet of drawings and premising
that although only two workers are referred to in the specification it is not
intended to limit the number to two. In the drawings Fig. 1 shows a cross
section of the gear and Fig. 2 a side view of the saddles and standards. The
workers sit side by side on saddles a having pins 6 sliding in the standards e for
enabling the height to be adjusted. The saddles are similar to those used on
cycles and handle bars d may be provided for supporting the workers and
enabling them to bring more power into use. If desired they could be employed
for steering purposes by attaching the rudder lines to them. The riders sit between
the handles which are brought forward under the riders arms. The saddles are so
arranged that the workers do not face the same way, one looking forward and the
other to the rear. (Fig. 2). Supported in suitable bearings e fixed to the bottom f
of the boat g is a crank shaft h (one for each rider) furnished with pedals i. Each
pedal revolves in a vertical plane parallel with one passing through the longitu-
dinal axis of the boat. On the inner end of each crank shaft is a toothed bevel
wheel each of which gears into an intermediate toothed bevel wheel k running
at right angles to the bevel wheels j. On the shaft of the intermediate wheel k
is a plain spur wheel m gearing (below) into a spur pinion n which in turn gears
in a pinion o threaded on and attached to the propeller shaft p. The propeller
shaft is supported in suitable plain and thrust bearings as usual. At one end of
the shaft is a screw propeller and on the same shaft may be a fly or balance
wheel. Suitable provision may be made for lubricating the various running
parts and the whole of the gear may be suitably cased in or covered to protect it
from damage. The action of the arrangement is as follows:-On the workers
rotating the crank shafts h by pedalling the bevel wheel j thereon will rotate
the intermediate wheel k. (The workers operating their respective pedals in
opposite directions ensures the rotation of k in one direction). The rotation of k 3
causes the rotation of m which in turn operates the pinions n and o, the latter of
which revolves the propeller shaft p.
As our invention is capable of some modification without departing from its
essential features we do not restrict ourselves precisely to the shapes, relative
proportions or disposition of parts shown in the drawings or mentioned in the
above specification, but may vary any or all of them according to circumstances.
For instance friction wheels might be used in place of spur or toothed wheels
and pinions

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 4
we claim is:-
1. Propelling life and other boats by foot onerated gearing the soid
coming

page_text: consisting essentially of two main toothed bevel wheels (on separate shafts) operat-
ing an intermediate toothed bevel wheel which carries round with it a
toothed wheel gearing into a pinion which in turn gears into a second pinion
plain
attached to the propeller shaft, the said main bevel wheels being rotated in one
and the same direction by cranks operated by the feet of two workers sitting
in opposite directions on suitably supported saddles one of which is situated
outside of each of the said main bevel wheels, the whole provided for and operated
substantially as described in the above specification and exemplified in the accom-
panying drawings.
2. Substituting friction for toothed wheels and pinions in the arrangements
mentioned in the preceeding Claim 1.
3. Propelling life and other boats by foot operated gearing arranged and operated
substantially as described in the above specification and exemplified in the
accompanying drawings.
