A Hydraulic motor.
I, MARIUS ANTOINE ROCHEGUDE, of 99, Boulevard de Montmorency, Paris, in
the Republic of France, Pilot, do hereby declare the nature of this invention
to be as follows:-
The present invention relates to a hydraulic motor which enables the vis-viva
of a water course to be utilized and which is applicable to various industrial
purposes, for example, the driving of dynamo machines for the electric lighting
of towns situated on water courses.
This motor consists essentially of two floating vessels strongly tied or con-
nected together and having between them endless ropes or belts, on which are
mounted movable paddles, and is characterised by the application of lateral
conduits formed in the sides or planking of the vessels for the purpose of bring-
ing the action of the exterior current upon the interior paddles of an unlocking
arrangement to enable a certain number of paddles to be put in position for
work to put the motor in rapid operation, and of an arrangement of locking
apparatus arresting the paddles in their swinging motion in such manner as to
prevent them from assuming their working position and thus effecting the stop-
page of the motor.
One method of carrying the invention into effect is illustrated in the accom-
panying drawings, which show the general arrangement of my motor.
Figs. 1 and 1 are an elevation showing the apparatus in working position.
Figs. 2 and 2 are an elevation showing the apparatus in its position of rest.
Figs. 3 and 3 are a plan.
Fig. 4 is a transverse half section to a larger scale.
Figs. 5, 6 and 6A are detail views, Fig. 5 showing in elevation the locking
arrangement for stopping the paddles, Figs. 6 and 6" representing in plan the
unlocking arrangement for setting the apparatus to work.
In all the figures, like parts are indicated by similar letters of reference.
My motor comprises two floating vessels A, strongly tied or connected together
At each
along their entire length and provided with water-tight divisions A'.
of their ends the two vessels are provided with bearings B, within which the
shafts B rotate; on these latter are mounted pulleys B³, which receive endless
belts C carrying articulated paddles D.
These belts Care constructed of a metallic body, covered preferably with an
envelope of gutta-percha or other suitable material.
In order that the motion of the belts may be effected regularly, these latter
are provided with eyelets, which successively engage with studs or pins arranged
around the peripheries of the pulleys B².
Each paddle D is composed of an iron frame, upon which are fixed blades of
wood, metal or other suitable material, and it can turn freely around a shaft
carried by bearings E" fixed on the bands C. The motion of each of these
paddles is limited by steel cables F.
In certain cases, when the water course will permit of it, in order to give
greater power to the motor, each paddle may be provided with supplementary
paddles D¹ fixed at a convenient height, either by binding screws or by bolts.

page_text: In order to prevent the bending of the belts, each shaft E and each paddle D,
carry pulleys G running on rails H, three at the upper part, two at the lower
part the number of these pulleys will vary according to the dimensions of the
apparatus. The rear pulleys have a greater diameter than those in front, so that
the upper parts of the belts may be inclined with a view to diminish friction
and to facilitate the motion of the apparatus. In front of the forward pulleys
is arranged a guideway H intended to guide the paddles during their swinging
motion and to thus deaden the shock.
Along the length of the vessels are formed in the planking or sides, water-
tight conduits I conducting the exterior current into the space comprised
between the two vessels or floats with the object of giving a new power to the
paddles.
The motor acquires its greatest speed when all the paddles are in action; in
order to be able to reduce this speed and even to stop it altogether, I apply the
following arrangement.
In front of the lower rails H are arranged two movable rails K capable of
running on pulleys L and operated by a lever M, see Figs. 1, 2 and 5. When
the movable rails K are moved to the rear, as shown at Fig. 1, the paddles D
can swing freely and be placed successively in working position; on the con-
trary, when the rails K are moved forward, as shown at Fig. 2, these rails con-
stitute a prolongation of the rails H and arrest the paddles D in their swinging
motion, in such manner that the lower pulleys of these paddles are placed on
the-same guideway or track as the pulleys carried by the shafts E, and the
paddles thus preserve a horizontal position."
In these conditions when the motor is required to work at great speed, the
lever M occupies the position represented at Fig. 1; on the contrary, if it is
desired to reduce the speed of the motor, this lever M is placed in the position
shown at Fig. 2. If this lever is left in this position during a sufficiently long
time, a moment will arrive when all the lower paddles will be in the horizontal
position; the motor will then stop.
My apparatus is further provided with an unlocking arrangement enabling the
motor to be rapidly put in operation. The lower rails H are interrupted at
certain points of their length; the spaces, in normal work, are occupied by
bolts N in such manner that the rails are continuous, see Figs. 6 and 6. These
bolts N are arranged in front of each other, and corresponding bolts are simul-
taneously operated. For this purpose two corresponding bolts are operated by
the same connecting rod 0; this connecting rod is articulated at one of its ends
to a lever P, which moves directly one of the bolts N, and at its other end to
a lever Q, which is itself articulated with the lever P¹ operating the second bolt.
In these conditions, by moving the connecting rod O in one or the other direc-
tion, two corresponding bolts are simultaneously opened or closed. By opening
thus simultaneously two bolts N, the paddle whose lower pulleys are supported
by these bolts, swings and is immediately placed in working position; as soon
as the motor is at work these bolts are automatically closed by the action of a
spring.
of
My motor is capable of various industrial applications; in the case supposed
motion is taken from the pulleys R keyed on the shaft of the rear pulleys of
the motor and is communicated to dynamo machines S by means
pulleys T, U, V. This dynamo machine may serve, for example, for the electric
lighting of towns situated on the water course which operates the motor, but
this application is mentioned merely as an example, as my motor is capable of
various other industrial applications.

I, MARIUS ANTOINE ROCHEGUDE, of 99, Boulevard de Montmorency, Paris, in
the Republic of France, Pilot, 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 present invention relates to a hydraulic motor which enables the vis-viva
of a water course to be utilized and which is applicable to various industrial
purposes, for example, the driving of dynamo machines for the electric lighting
of towns situated on water courses.
This motor consists essentially of two floating vessels strongly tied or con-
nected together and having between them endless ropes or belts, on which are
mounted movable paddles, and is characterised by the application of lateral
conduits formed in the sides or planking of the vessels for the purpose of bring-
ing the action of the exterior current upon the interior paddles, of an unlocking
arrangement to enable a certain number of paddles to be put in position for
work to put the motor in rapid operation, and of an arrangement of locking
apparatus arresting the paddles in their swinging motion in such manner as to
prevent them from assuming their working position and thus effecting the stop-
page of the motor.
One method of carrying the invention into effect is illustrated in the drawings
accompanying my Provisional Specification which show the general arrangement
of my motor.
Figures and 1 are an elevation showing the apparatus in working position.
Figures 2 and 2* are an elevation showing the apparatus in its position of
rest.
Figures 3 and 3* are a plan.
Fig. 4 is a transverse half section to a larger scale.
Figures 5, 6 and 6 are detail views. Fig. 5 showing in elevation the lock-
ing arrangement for stopping the paddles. Figs. 6 and 6 representing in plan
the unlocking arrangement for setting the apparatus to work.
In all the figures, like parts are indicated by similar letters of reference.
My motor comprises two floating vessels A strongly tied or connected together
along their entire length and provided with water tight divisions A¹.
At each of their ends, the two vessels are provided with bearings B within
which the shafts 13 rotate; on these latter are mounted pulleys B² which
receive endless belts C carrying articulated paddles D.
These belts C are constructed of a metallic body, covered preferably with an
envelope of gutta-percha or other suitable material.
In order that the motion of the belts may be effected regularly, these latter
are provided with eyelets which successively engage with studs or pins arranged
around the peripheries of the pulleys B⁹.
Each paddle D is composed of an iron frame, upon which are fixed blades of
wood, metal or other suitable material, and it can turn freely around a shaft E
carried by bearings E' fixed on the bands C.
The motion of each of these paddles is limited by steel cables F.
In certain cases, when the water course will permit of it, in order to give
greater power to the motor, each paddle may be provided with supplementary
paddles D fixed at a convenient height, either by binding screws or by bolts.
In order to prevent the bending of the belts, each shaft E and each paddle D,
carry pulleys G running on rails H, three at the upper part, two at the lower
part; the number of these pulleys will vary according to the dimensions of the
apparatus.

page_text: The rear pulleys have a greater diameter than those in front, so that the
upper parts of the belts may be inclined with a view to diminish friction and to
facilitate the motion of the apparatus.
In front of the forward pulleys is arranged a guideway H¹ intended to guide
the paddles during their swinging motion and to thus deaden the shock.
Along the length of the vessels are formed in the planking or sides, water-
Eight conduits I conducting the exterior current into the space comprised
between the two vessels or floats, with the object of giving a new power to the
paddles.
The motor acquires its greatest speed when all the paddles are in action; in
order to be able to reduce this speed and even to stop it altogether, I apply the
following arrangement.
In front of the lower rails H are arranged two movable rails K capable of
running on pulleys L and operated by a lever M, see Figures 1, 2 and 5.
When the movable rails K are moved to the rear, as shown at Fig. 1, the
paddles D can swing freely and be placed successively in working position, on
the contrary, when the rails K are moved forward, as shown at Fig. 2, these
rails constitute a prolongation of the rails H and arrest the paddles D in their
swinging motion, in such manner that the lower pulleys of these paddles are
placed on the same guide way or track as the pulleys carried by the shafts E
and the paddles thus preserve a horizontal position.
In these conditions when the motor is required to work at great speed, the
lever M occupies the position represented at Fig. 1 on the contrary if it is
desired to reduce the speed of the motor, this lever M is placed in the position
shown at Fig. 2. If this lever is left in this position during a sufficiently long
time, a moment will arrive when all the lower paddles will be in the horizontal
position; the motor will then stop.
My apparatus is further provided with an unlocking arrangement enabling
the motor to be rapidly put in operation.
The lower rails H are interrupted at certain points of their length, the spaces,
in normal work, are occupied by bolts N in such manner that the rails are con-
tinuous see Figures 6 and 6^.
These bolts N are arranged in front of each other, and corresponding bolts
are simultaneously operated.
For this purpose two corresponding bolts are operated by the same connecting
rod 0; this connecting rod is articulated at one of its ends to a lever P which
moves directly one of the bolts N and at its other end to a lever Q which is
itself articulated with the lever P¹ operating the second bolt.
In these conditions, by moving the connecting rod in one or the other direc-
tion, two corresponding bolts are simultaneously opened or closed.
By opening thus simultaneously two bolts N, the paddle, whose lower pulleys
are supported by these bolts, swings and is immediately placed in working posi-
tion; as soon as the motor is at work, these bolts are automatically closed by
the action of a spring.
My motor is capable of various industrial applications; in the case supposed
motion is taken from the pulleys R keyed on the shaft of the rear pulleys of
the motor and is communicated to dynamo machines S by means of pulleys T, U, V.
This dynamo machine may serve for example, for the electric lighting of towns
situated on the water course which operates the motor, but this application is
mentioned merely as an example, as my motor is capable of various other indus-
trial applications.
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:
1. A hydraulic motor consisting of two floating vessels connected or tied
together carrying between them endless ropes or belts with eyelets upon which

page_text: are mounted movable paddles in combination with lateral conduits formed in the
sides of the vessels for the purpose of bringing the action of the exterior current
upon the interior paddles, substantially as herein set forth.
2. In a hydraulic motor, the combination of two floating vessels connected or
tied together carrying between them endless ropes or belts upon which are
mounted movable paddles with an unlocking arrangement for starting the motor
rapidly consisting of bolts N which normally fill up spaces in the lower rails H,
the spaces in each rail corresponding always in such a way that in opening two
corresponding bolts, the paddle, the lower pulleys of which are supported by
these bolts, swings and is immediately placed in working position, substantially
as herein shown and described.
3. In a hydraulic motor, the combination of two floating vessels connected or
tied together carrying between them endless ropes or belts upon which are
mounted movable paddles, with a locking arrangement for stopping the motor,
consisting of two movable rails K, forming when they are pressed forward, a
prolongation of the lower rails H and thus stopping the paddles D in their
swinging movement in such a manner that the lower pulleys of the paddles are
placed upon the same guide way or track as the upper pulleys of these paddles,
substantially as herein shown and described and for the purpose stated.
