Improvements in Water-raising Apparatus.
1, GUSTAVE TROUVÉ, of 14, Rue Vivienne, Paris, France, Electrical Engineer.
do hereby declare the nature of this invention to be as follows:-
-.
My invention relates to water-raising apparatus of which the action is based on
the principle involved in the physical phenomenon known as a water-spout, the
liquid being raised by the force due to a rapid gyratory motion similar to that
acquired by the mass of water in the case of a water-spout. The main part of the
apparatus is a drum of approximately conical form and made to revolve about its
axis, into which the water is introduced in the axial direction at its smaller end, the
water being carried round with the rapidly rotating drum and becoming raised to a
height dependent upon the velocity of rotation and upon other conditions hereafter
referred to.
An example of my invention is illustrated in the accompanying drawings, forming
part of this Specification, in which
Figure 1 represents a vertical section of my improved water-raiser.
Figure 2 is an elevation, and Figure 3 a longitudinal vertical section of an
arrangement in which a helix is combined with the conical drum.
Figure 4 is a cross-section, on line 1-2, Figure 3.
Figure is a vertical section, and Figure 6 an elevation of a modification.
The same letters of reference indicate the same parts in all the figures.
a is a base plate upon which the casing is supported. Within this casing is
fitted to revolve the conical drum e which may, if desired, be provided with a
cylindrical extension d. In order that the drum c, d, may be rapidly revolved, it is
mounted by means of suitable cross arms e upon a shaft journalled at one end in
cross arms g, its other end passing out through a stuffing-box and being provided
with a driving pulley i.
In Figures 1 and 3 the drum e is a right cone with straight sides, while in
Figure 5 it is hemispherical or preferably a zone or segment of a sphere, but any
other surface of revolution having any form of generatrix may be adopted, provided
that the transverse area increases from the point of admission of the water to its
point of discharge.
The water is admitted at the inlet k and on entering the cone is carried round by
it in its rotation and expelled through the delivery pipe I, which receives the water
at the circumference of the casing against which it is projected by the centrifugal
force, for which purpose the pipe is connected with the interior of the easing by a
pocket p.
In Figure 1 the apparatus comprises only the essential part by which the raising
and forcing of the water is effected, the cone which has a cylindrical
extension d, but the latter may be dispensed with.
I may combine with the coue any adjunct capable of increasing the effect of the
apparatus. Thus, in Figures 3 and 5, the action of the cone is assisted by a helical
blade m mounted within, and revolving with, the cone, but this helix is merely an
auxiliary, since the direction of motion of the liquid through the apparatus is
always in the direction indicated by the arrows X and Y whichever may be the
direction of rotation of shaft f. In the one case, however, the action of the helix
will be added to that of the cone and the water will be raised to a greater height

page_text: than with the latter alone, while in the other case the helix offers a resistance to
the flow of the water and the height to which the latter will be raised is less than
with the cone alone. This fact clearly demonstrates the peculiar action of the cone
and the power of the effect produced by it.
The form, dimensions, and details of arrangement of the several parts of the
apparatus may be varied without in any way departing from the invention, which
resides essentially in the employment for forcing and raising liquids by means such
as herein described, whereby the liquid is caused to receive rapid gyratory motion
and is caused to advance through areas of constantly increasing diameter from the
point of admission to the point of discharge.
Several such apparatus may be grouped together especially by mounting them
on a comman shaft and causing them to act in succession upon the liquid for the
purpose of increasing either the output or the pressure.

I, GUSTAVE TROUVÉ, of 14, Rue Vivienne, Paris, France, Electrical 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:-
My invention relates to water-raising apparatus of which the action is based on
the principle involved in the physical phenomenon known as a water-spout, the
liquid being raised by the force due to a rapid gyratory motion similar to that
acquired by the mass of water in the case of a water-spout. The main part of the
apparatus consists of a drum of approximately conical form made to revolve about
its axis, into which the water is introduced in the axial direction at its smaller end,
the water being carried round with the rapidly rotating drum and becoming raised
to a height dependent upon the velocity of rotation and upon other conditions
hereafter referred to.
An example of my invention is illustrated in the drawings accompanying my
Provisional Specification, in which
Figure 1 represents a vertical section of my improved water-raiser.
Figure 2 is an elevation, and Figure a longitudinal vertical section of an
arrangement in which a belix is combined with the conical drum.
Figure 4 is a cross section, on line 1-2 Figure 3.
Figure 5 is a vertical section, and Figure 6 an elevation of a modification.
The same letters of reference indicate the same parts in all the figures.
a is a base plate upon which the casing is supported. Within this casing bis
fitted to revolve the conical drum c which may, if desired, be provided with a
cylindrical extension d. In order that the drum c, d, may be rapidly revolved, it
is mounted by means of suitable cross arms e upon a shaft journalled at one end
in cross arms g of the casing, its other end passing out through a stuffing-box / and
being provided with a driving pulley i.
In Figures 1 and 3 the drum is a right cone with straight sides, while in
Figure 5 it is hemispherical or preferably a zone or segment of a sphere, but any
other surface of revolution having any form of generatrix may be adopted, provided
that the transverse area increases from the point of admission of the water to its
point of discharge.
The water is admitted at the inlet & and on entering the cone is carried round by
it in its rotation and expelled through the delivery pipe l, which receives the water

page_text: at the circumference of the casing 6 against which it is projected by the centrifugal
force, for which purpose the pipe is connected with the interior of the casing by a
pocket p.
In Figure 1 the apparatus comprises only the essential part by which the raising
and forcing of the water is effected, ei.-the cone e which has a cylindrical
extension d, but the latter may be dispensed with.
may also combine with the cone any adjunct capable of increasing the effect of
the apparatus. Thus, in Figures 3 and 5, the action of the cone is assisted by a
helical blade m mounted within, and revolving with, the cone but this helix is
merely an auxiliary, since the direction of motion of the liquid through the
apparatus is always in the direction indicated by the arrows X and Y whichever
may be the direction of rotation of shaft. In the one case, however, the action
of the helix will be added to that of the cone and the water will be raised to a
greater height than with the latter alone, while in the other case the helix offers a
resistance to the flow of the water and the height to which the latter will be raised
is less than with the cone alone. This fact clearly demonstrates the peculiar action
of the cone and the power of the effect produced by it.
The form, dimensions, and details of arrangement of the several parts of the
apparatus may be varied without in any way departing from the invention,
which resides essentially in the employment for forcing and raising liquids, or
semi-liquid matters, of means such as herein described, whereby the liquid is caused
to receive rapid gyratory motion and is caused to advance through areas of
constantly increasing diameter from the point of admission to the point of
discharge.
Several such apparatus may be grouped together especially by mounting them
on a common shaft and causing them to act in succession upon the liquid for the
purpose of increasing either the output or the pressure.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1st. The herein described apparatus for raising liquids, or semi-liquids, constructed
and operating as specified.
2nd. The respective arrangements of liquid-raising apparatus, substantially as
illustrated in the respective figures of the drawings.
