Marseilles, in the French Republic, Engineers, do hereby declare the nature of
this invention to be as follows:-
-
This invention relates to an improved water or fluid motor based on a novel
application of the well-known Archimedean principle respecting the submersion
of bodies in fluids.
Our improved motor is composed of a number of floats or cylinders of variable
capacity or displacement joined together so as to form a continuous chain and
arranged to pass around four guide-wheels, one of which is secured on the driving
shaft. Owing to their variable capacity these cylinders or floats successively
descend and rise in water or other fluid contained in a tank or reservoir thereby
producing without expense mechanical force applicable to various industrial
purposes.
Upon the accompanying drawings illustrating our invention―
Figure 1 is a vertical section of a tank or reservoir of water or other fluid, the
motor within it being shewn in side elevation.
Figure 2 is a sectional elevation through line A-B of Figure 3 of the same
reservoir, with a front elevation of the motor.
Figure 3 is a plan view of the motor placed in the tank or reservoir.
Figure 4 is a part plan view of a modification of motor separate from the tank.
As will be seen from the drawings, our improved water or fluid motor con-
sists of
1. A tank or reservoir K of sheet-iron or other suitable material capable of con-
taining fluids, within which tank the mechanism is arranged.
2. A number of floats or cylinders of variable capacity immersed in the
reservoir: -on the drawings cylindrical floats of gun-metal are shewn furnished
with pistons, but they may be constructed of other forms and materials, for
instance of inflatable rubber casings collapsing and expanding like the bellows of
a forge or of an accordion; (see F Figure 4).
3. Connecting-links or bars B joining the floats together:-the arrangement
shewn on the plan may be replaced by other connecting devices effecting the same
purpose.
4. Small tubes T establishing constant communication between all the floats
to ensure the free circulation of air throughout the series.
5. Two toothed wheels C one at the top and the other at the bottom of the
reservoir K; these toothed wheels impart motion to pinions ? passing over them
in one direction or the other, and by means of screwed rods V effect the inward
or outward movement of pistons P and consequently the alteration of the capacity
of the floats or cylinders.
It will be seen that each screwed rod operates two pistons P coupled together
by cross-bars t, and that a single pinion p causes the movement of four pistons.

be caused by the disturbance of the equilibrium of the floats in the water.
fact the pistons P are not all at the same height in the cylinders, from which it
results that:-
In
1st. After passing over the upper toothed wheel the cylinders Nos. 1 to 6 having
their pistons all at the bottom and being necessarily full of water, tend-by
reason of their weight-to descend.
2nd. The cylinders Nos. 7 to 10 travel horizontally at the bottom of the tank K,
and their pinions p engaging with the toothed wheels C, withdraw the pistons P
and the cylinders or floats F are re-filled with air on passing to the position shewn
at the bottom right side on Figure 3.
3rd. The cylinders 11 to 16 filled with air, as has been stated, displacing a
volume of water equal to their external measurement will tend to ascend; and
4th. Cylinders 17 to 20 at the top of the tank operate the return of the pistons
within the cylinders, by the action of pinions 2 working on toothed wheel C, as
they return to the position of cylinder No. 1 and commence a new cycle.
The above description of the first chain of the motor applies also to the second
chain shewn on the drawings; it is evident that the number of floats or cylinders
composing a chain, as well as the number and arrangement of the chains, may be
varied according to the power required and the particular purpose to which the
motor is to be applied.
It should be observed that the gross volume of air in this machine does not
change, since the pistons of the lower cylinders are constantly withdrawn from the
bottom, whilst those of the upper cylinders are forced inwards, and the air can
circulate only through the whole series of cylinders.
We, MICHEL NIUBO and SAUVEUR THERAIZOL, both of 21, Rue des Bergers,
Marseilles, in the French Republic, 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 water or fluid motor based on: a novel
application of the well-known Archimedean principle respecting the submersion of
bodies in fluids.
Our improved motor is composed of a number of floats or cylinders of variable
capacity or displacement joined together so as to form a continuous chain and
arranged to pass around four guide-wheels, one of which is secured: on the driving
shaft. Owing to their variable capacity these cylinders or floats successively
descend and rise in water or other fluid contained in a tank or reservoir thereby
producing without expense mechanical force applicable to various industrial pur-
poses. On the drawings filed with our Provisional Specification illustrating our
invention,
Figure 1 is a vertical section of a tank or reservoir of water or other fluid, the
motor within it being shewn in side elevation.

page_text: Figure 2 is a sectional elevation through line A-B of Figure 3 of the same
reservoir, with a front elevation of the motor.
Figure 3 is a plan view of the motor placed in the tank or reservoir.
Figure 4 is a part plan view of a modification of the motor separate from the
tank.
As will be seen from the drawings, our improved water or fluid motor con-
sists of
(1). A tank or reservoir K of sheet iron or other suitable material capable of
containing fluids, within which tank the mechanism is arranged.
(2). A number of floats or cylinders F of variable capacity immersed in the
reservoir; on the drawings cylindrical floats of gun-metal are shown furnished
with pistons, but they may be constructed of other forms and materials, for
instance of inflatable rubber casings collapsing and expanding like the bellows of
a forge or of an accordion; (see F', Figure 4.)
(3). Connecting-links or bars B joining the floats together; the arrangement
shewn on the plan may be replaced by other connecting devices effecting the same
purpose.
(4). Small tubes T establishing constant communication between all the floats
to ensure the free circulation of air throughout the series.
(5). Two toothed racks C one at the top and the other at the bottom of the
reservoir K; these toothed wheels impart rotation to pinions ? passing over them
in one direction or the other, and by means of screwed rods V effect the inward
or outward movement of pistons P and consequently the alteration of the capacity
of the floats or cylinders.
It will be seen that each screwed rod operates two pistons P coupled together by
cross-bars, and that a single pinion ? causes the movement of four pistons.
(6). Four axles A each carrying two wheels R over which the floats F pass, one
of these axles also carries the driving-pulley M and a brake for stopping the
motor.
(7). Suitable rollers g for the purposes of guiding the chain of floats and of
preventing the disengagement of the pinions p with, and during their passage
over, the teeth of the racks C.
From the foregoing description it will be readily understood that movement
will be caused by the want of, or the disturbance of, the equilibrium of the floats
in the water. In fact the pistons P (sce Figure 3) are not at all at the same height
in the cylinders, from which it results that, 1st, after passing over the upper
toothed rack the cylinders Nos. 1 to 6 have their pistons all at the bottom and
being necessarily full of water tend--by reason of their weight to descend. 2nd ;
the cylinders Nos. 7 to 10 travel horizontally at the bottom of the tank K, and
their pinions engaging with the toothed racks C, withdraw the pistons P and the
cylinders or floats F are re-filled with air on passing to the position shewn at the
bottom right side on Figure 3. 3rd; the cylinders 11 to 16 filled with air, as has
been stated, displace a volume of water equal to their external capacity or move-
ment and will tend to ascend; and, 4th, cylinders 17 to 20 at the top of the tank
operate the return of the pistons within the cylinders, by the action of pinions p
working on toothed rack C, as they return to the position of cylinder No. 1 and
commence a new cycle.
ገ
The above description of the first chain of the motor applies also to the second
chain shewn on the drawings; it is evident that the number of floats or cylinders
composing a chain, as well as the number and arrangement of the chains, may be
varied according to the power required and the particular purpose to which the
motor is to be applied.
It should be observed that the gross volume of air in this machine does not
change, since the pistons of the lower cylinders are constantly withdrawn from
the bottom, whilst those of the upper cylinders are forced inwards, and the air
can circulate only through the whole series of cylinders.

page_text: 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 water or fluid motor characterized by a series or chain of expansible
floats with pistons P respectively, and by inflatable bellows floats F', communi-
cating with each other, which floats enclose each a volume of air varying according
to their position, whilst the total volume of air in the series of floats remains
constant, as described.
(2). A water or fluid motor characterized by a chain of cylinders or floats with
pistons, and by inflatable bellows' floats, communicating with each other, in which
the pistons P of expansible floats F opposed.in two series or chains to the inflatable
bellows floats F1 respectively, are operated by two rods t screwed right and left
upon a screwed rod V controlled by a pinion p, which by engaging in turn with
toothed racks C at the bottom and top of a reservoir of water, drives the pistons P
first in one direction and then in the other, respectively inflating and then
deflating the expanding floats F1, substantially as described.
(3). The improved water or fluid motor, constructed, combined and arranged to
operate as described and illustrated on the annexed drawings.
