Improvements in and relating to Boats and the like.
I, MARIUS CHENIVESSE, of 79, Rue des Martyrs, Paris, in the Republic of France,
Engineer, 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 improvements in boats and the like propelled by a
motor of any kind and comprises a system which can be applied to such vessels
for the purpose of rendering them practically unsinkable and uncapsizable, so that
they may be of great service for all purposes where saving of life of passengers
and crews is in question.
The annexed drawing shows a boat constructed according to this invention.
Fig. 1 is a longitudinal section on the line W W of Fig. 2.
Fig. 2 a plan of the improved boat.
Figs. 3, 4 and 5 are cross sections on the lines X X, V V and Y Y of Fig. 2
respectively; Fig. 5 being a part section only and on a larger scale.
The reference numbers 1 to 24 show air compartments which may be constructed
of any suitable shape or form and of metal, wood or any other suitable material.
These compartments are constructed according to the build and purpose of the
boat and may be of any convenient number.
Each of the said compartments or air chambers may be provided with a hole, or
aperture 6 in the lower part, which may be kept closed if required by means of a
screw plug or by any other convenient method, a similar aperture may be in the
upper part of each chamber; these apertures serve to let the water run out from
the air compartments and to admit air thereto. in the event of any getting in,
but there is no direct communication between the air-chambers and the water in
which the boat may be floating.
The centre of the boat may be provided with an air and water tight chamber r
enclosing the fly-wheel of the motor B for the purpose of allowing the motor to
maintain its speed when the boat is submerged or partly submerged, the advantage
of this chamber being that the fly-wheel of the said motor can maintain the desired
number of revolutions in spite of water which may be in the vessel.
and y represent two valves for the purpose of letting water into the water
hallast compartment A, running the whole length of the vessel, to increase the
displacement and prevent the vessel from capsizing. and y represent two
valves for escape of air from the said compartment.
The air chambers 1 to 24 and 5 to 18 may be arranged under the side seats
and thwarts of the boat or in other positions. This circuit of air chambers under
the side seats prevents these spaces being otherwise occupied, and thus keeps the
weight of passengers and goods more central so as to prevent the rolling of the
boat. The water which has been let into the water ballast compartment A through
the beforementioned valves prevents the boat capsizing.
If the water let in the compartment A is not sufficient to give the desired depth
of immersion to the boat, more water can be admitted through an opening above

page_text: the flooring of the boat. This is in case there should only be a few passengers on
board and it is necessary to increase the displacement.
A pump for filling or emptying the water ballast compartment or the open well
above it, operated by a lever or wheel or other suitable means, may be connected
with the propeller shaft, so that by its aid the boat may be kept on an even keel
or its displacement increased or diminished, as required, and thus all the force
of the motor can be concentrated if necessary for removing the water.
The pump may also be operated without stopping the motor, by connecting the
same and the propeller with the shaft at the same time for the purpose of ballasting
the boat more deeply if necessary to prevent capsizing or lightening it in fine
weather to increase its speed.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A boat or vessel as herein described and shown in the drawing, comprising
air chambers, a water ballast chamber and valves and pump for filling or emptying
the latter.
2. The construction of a boat as herein described and illustrated, with air com-
partments 1-24, water ballast A, motor fly-wheel encasement r, valves y and
pump v, the boat being adapted to be driven by a motor which may also be used
for driving the pump by connection of the latter to the propeller shaft.

COMPLETE SPECIFICATION.
Improved Motor, principally intended for the Propulsion of Boats,
Ships, or the like.
I, MARIUS CHENIVESSE, of 30, Rue Frere, Orban Molenbeck, St. Jean, Bruxelles,
in the Kingdom of Belgium, Engineer, 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 subject of the present invention is a motor for propelling vessels, which
can be easily fitted up in any ship or boat upon a suitable frame. The motor has
the great advantage of being in working order at any time, without any pre-
paration or expense. Vessels fitted with this motor behave just as well in rough
water as in smooth, and can be navigated forwards or backwards without it
being necessary to slow down or stop the motor. The motor is preferably driven
by manual power, and consists principally of a series of levers, and gear wheels
by which the propeller is actuated.
The annexed drawing represents an example of the motor the frame upon
which it is mounted being removed.
Fig. 1 is a side view of the motor with the operating lever in horizontal
position.
Fig. 2 is a side view with the operating lever in an inclined position.
Fig.
is a vertical section on the line of Fig. 1.
Fig. 4 is a vertical section on line Y-Y of Fig. 1.
Fig. 5 is a side view of part of the operating lever A.
Fig. 6 is a side view principally of the angle-lever B.
Fig. 7 is a side view of the angle lever C.
Fig. 8 shows the reversing apparatus or clutch mechanism in position for
backward movement of the vessel.
Fig. 9 shows the latter in position for forward movement.
Fig. 10 shows the said apparatus when out of action.
Fig. 11 is a front view of the clutch coupling fork with its bearings.
The system and method of working this motor is as follows:-
The operating lever A which sets the whole system in motion, is oscillated
by hand round its pivot, namely the shaft 4, by means of the handles a a fixed
to the ends thereof.
In the operating lever A is formed a guiding groove or slot 6, in which the
roller c moves. The latter being attached to one end of the angle lever B. The
said angle lever B, moving in double bearings is fulcrummed upon the shaft 1,
and has attached to it a pawl é which engages into the ratchet wheel f, fixed
on the said shaft 1. Fixed to the shaft 4, which as above mentioned, forms the
fulcrum of the operating lever, is the double lever g, gearing into the groove or
slot in the angle lever C by means of a pin g at its end. On a branch of the
said lever C, which is also pivoted on the shaft 1, there is pivoted a pawl el, also
engaging into the ratchet wheel f. When the lever A is pressed down towards
that side of its pivot on which the groove or slot 6 is situated, the pawl e, sets
the ratchet wheel f in rotary motion, in consequence of the movement imparted
to the angle lever B, which slides in the groove or slot and is pivoted ou

page_text: shaft 1 whilst the lever C is moved in the contrary direction, so that the pawl el
is moved back for a certain number of teeth. When the operating lever A is
pressed down to the other side, the pawl e will act upon the ratchet wheel f
in the same manner as in the case of the pawl e, that is to say, it will set the
ratchet wheelf in rotary motion in the same direction whilst at the same time
pawl e is moved back for a certain number of teeth. Therefore by the continuous
swinging movement of the operating lever A, the ratchet wheel f and with it
the shaft 1 on which it is keyed or otherwise fixed will be set in continuous
rotary motion in one direction. In order to utilize this rotary motion for the
propulsion of a ship or boat it is transmitted to a propeller in the following
manner.
At the side of ratchet wheel f and on the same shaft 1 a spur wheel is
fixed. This spur wheel gears with a pinion k fixed on a second shaft 2, and
a further spur-wheel , also fixed on said shaft 2 drives a pinion m fixed on
the axle 3. The latter also carries bevelled toothed wheel n, which gears with
two bevelled wheels o and o¹, running loosely upon the propeller shaft p. These
latter bevelled wheels which drive the screw propeller shaft and thus set the
vessel in motion, are connected with a reversing or clutch mechanism, by which
forward or backward movement or stoppage of the vessel is controlled. In this
reversing or clutch mechanism, the coupling sleeve P, which turns with and
also has lateral movement along shaft p, has at its two ends the coupling clutches q
and g. There is also a collar on the sleeve P', into which the teeth s on the
fork of the reversing lever gear. Either of the bevelled wheels and o¹ can
be thus geared to drive the shaft by means of the coupling pins of the correspond-
ing coupling.clutch q or q¹.
As shown in the drawing (Fig. 8 to 11), the sleeve P can either be geared
to the bevel wheel o or the bevel wheel of or to neither of them, by means of
the reversing lever and fork t. A fly wheel is fixed on to the propeller shaft 2.
in order to obtain smoothness of working.
Any other method of transmission gear may be employed according to the exist-
ing circumstances.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
A manually operated motor principally intended for the propulsion of ships,
boats and the like, comprising an operating lever A, adapted to be set in
oscillating motion round its fulcrum, 4, the said lever actuating simultaneously
two angle levers B and C, each of which is provided at its end with a pawl e or e¹
respectively, in such a manner that the said two pawls e and e¹ alternately set
a ratchet wheel f in continuous rotary motion, which motion is transmitted
to a propeller shaft p connected with the vessel's screw, substantially as
described.
