PROVISIONAL SPECIFICATION.
Rotary Apparatus for Lifting, Forcing, and Mixing Liquids, and for
Propelling Vessels.
I, GUSTAVE TROUVÉ, of 14, Rue Vivienne, Paris, France, Electrical Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for lifting, forcing, and mixing liquids
and for the propulsion of vessels, and consists more particularly of a rotary double
or multiple acting apparatus in which two truncated conical surfaces are mounted
on a common shaft and with their larger or smaller ends facing each other and
revolve within a casing in such manner that by the rapid rotary motion of the
cones, the liquid is drawn in at the smaller ends of the cones and discharged at
the larger ends. These hollow truncated cones may be provided on their interior
with a helicoidal partition or preferably with a plane longitudinal partition to
permit of the apparatus rotating in either direction, said partition serving to
increase the production of the apparatus, especially when the cones are driven
at a considerable speed.
The apparatus may also consist of a single cylindro-conical casing within
which rotates, as in a bearing, a body of similar form keyed upon a central
driving shaft carrying an exhausting and forcing screw of slow pitch. The
water which enters at the smaller end of the cone is drawn in by the rapid motion
of the central revolving body and is delivered at a height which depends upon
the velocity of rotation. Thus the product of the apparatus being a function
of the velocity it is always possible to obtain a very considerable outflow which
renders the apparatus especially suitable for use, for example, in raising a sunken
vessel, extracting the water from a flooded mine, etc.
The apparatus is adapted for raising water from wells, mines, and for use in
civil and military engineering works, as a water engine for agricultural purposes,
and pump for decanting wines, etc.
The apparatus is also adapted to serve as an efficient propeller for vessels by
drawing in water at the bow and expelling it at the stern.
The invention is illustrated by way of example in the accompanying drawings
wherein Figure 1 is an elevation of the apparatus; Figure 2 a longitudinal sec-
tion and Figure 3 a transverse section on line 1-2 Figure 2. Figures 4 and 5
shew modifications of the apparatus. Figures 6 and 7 shew the apparatus dia-
grammatically, as applied to the propulsion of vessels. In Figures 8 to 15 single
acting apparatus based upon the same principle and adapted for the same uses are
illustrated; Figure 8 is a vertical section of such an apparatus, the same apparatus
being shewn in Figure 9 as driven by a dynamo-electric machine. In Figure 10
the apparatus is shewn as applied for raising water from a well. Figure 11 is
a side elevation, and Figure 12 a front elevation of the apparatus mounted on
a tandem cycle for use as a fire-engine or pump: Figure 13 shews a hand-
operated apparatus, and Figure 14 a modification of the latter arrangement, while

page_text: in Figure 15 the apparatus is shewn as applied to the propulsion of vessels. The
same letters of reference denote like parts in all the figures.
Referring to Figures 1 to 3 the apparatus consists essentially of two truncated
conical surfaces a mounted upon a common shaft b with their larger ends facing
one another, the, shaft being capable of revolving freely in stuffing boxes c d.
Each of the truncated cones may, however, be replaced by a conoidal figure of any
form generated by the revolution of a compound rectilinear or of a curvilinear
(concave or convex) generatrix, providing that the transverse section of such
conoidal passages gradually increases from the point of admission of the water
to its point of discharge. The casing e is provided at each end with a chamber
upon which is branched a pipe f while at the centre of the casing there is a
branch pipe which opens into the space comprised between the ends of the
cones a a, the sectional area of the pipe g being however at least equal to the
sum of the areas of the two branches ff. In this example the branch pipes f f
open out from the smaller inlet ends of the cones and form the suction orifices.
the central branch pipe g being the delivery. The heads or chambers are of
larger diameter than the branches f in order to form a reservoir in front of each
truncated cone and facilitate the passage of the liquid thereto. The cones a are
each provided with a tubular extension h which revolves, as in a bearing, within
the cylindrical part of casing e, clearance, however, being left between the
casing and the surface of the cones. By this construction back flow of the liquid
towards the suction inlet, and resistance to the efficient working of the apparatus,
is prevented but other means for attaining the same end may be employed. The
shaft extends beyond the ends of the casing and is provided at
(or at both ends) with a pulley j driven by any suitable source of power. The
heads are preferably attached to the ends of the casing e by flanges and bolts,
so that they may be turned as desired, but they may be fixed in any other
suitable manner. Similarly the delivery branch may be fixed to the casing or be
mounted so as to be capable of turning in any direction desired.
one end
In order to increase the output of the apparatus, each truncated cone is provided
with an internal partition of helicoidal form or preferably disposed in one of the
median planes of said cone, as shewn in Figure 3. This latter arrangement
permits of the apparatus being revolved in either direction and presents the
advantage of producing a very large output especially when the cones are driven
at a very high velocity.
In certain cases, in order that the stream of liquid may be deprived of all
whirling movement and be consequently projected from the apparatus in an
absolutely straight line, the delivery branch may have an internal partition g'
dividing it into two equal parts, as shewn in Figure 4.
The combination of these two truncated cones with their larger ends facing
cach other so that the two jets of liquid become mixed on delivery, enables a
very large output to be obtained and one much greater than that which could be
obtained with two apparatus each containing a single truncated cone only. In
this apparatus the forces which tend to impart to the shaft a movement of trans-
lation, balance one another. This is of the utmost importance in view of the
great velocity at which the apparatus revolves, especially as regards wear of the
parts, for as the machine is constantly balanced, friction is reduced to a minimum.
Figure 5 shews a variation in which the smaller ends of the truncated cones
are opposed to one another, the apparatus in this case having a single inlet
and two delivery outlets f.
Figures 6 and 7 shew diagrammatically the application of the apparatus as a
propeller. The apparatus in Figure 6 comprises two suction pipes f f and a
single delivery pipe 9, while in Figure 7 there is a single central suction pipe
and two delivery pipes, this latter arrangement enabling the vessel to be steered
by varying the outflow or by cutting off one delivery pipe by means of suitable
valves. In both cases the delivery pipe or pipes discharge at the after end, and
the inlet pipe or pipes at the fore end, of the vessel either at the sides or at

page_text: the ends, as shewn. The delivery pipes may be provided with a number of
branches so as to obtain a series of jets acting at different- points simultaneously.
The apparatus, when applied to vessels, may constitute a means for preventing the
vessel from sinking in consequence of injury to the hull, as by the employment
of suitable valves the apparatus may be immediately converted into a pump,
while still retaining its use as a propeller. Any number of these apparatus
may be employed in combination either mounted upon a single shaft, the one
behind the other, or radiating from a centre.
The apparatus may be constructed with but a single truncated cone (see
Figure 8) in which case it comprises a casing e with an inlet f and a delivery 7.
The coned part e of the pump casing is provided at the inlet end with a short
cylindrical part within which is fitted, as in a bearing, a tubular extension h
terminating in a truncated conical part a which is received within the casing e,
the necessary clearance being left between them as before. The coned part e is
mounted centrally within the pump casing upon a tapered shaft journalled in
stuffing boxes c d and carrying a helix of slow pitch. The shaft may be
extended at 2 and carry a driving pulley, as shewn in Figures 13, 14, and 15,
or it may be coupled to the shaft of a dynamo Z or other machine, as in Figures 9
and 11. The stuffing box e in head is provided with a centre m for the shaft b
to turn against.
Figure 10 shews the apparatus applied as a well pump comprising a post n
upon which are mounted winch handles o p for driving the bevel gear wheel g
and pinion keyed on the prolongation 12 of shaft b. s is the suction pipe
which extends down into the well and is provided with a valve for keeping the
pump primed, and is the flow pipe which extends upwards to any suitable
point.
In Figures 11 and 12 a water tank is mounted on the cycle and the pump
is mounted on the top of the tank and is driven by a dynamo.
Figure 13 represents the apparatus arranged as a hand pump to be operated
by two crank handles w. The apparatus may be either permanently or tem-
porarily fixed or be transported by placing it upon a truck and fixed by means
of a base plate a.
Figure 14 shews the pump as mounted upon a pillar, which also carries the
driving gear comprising a pair of crank handles wkeyed on a shaft y mounted
in the pillar below the top upon which the pump is fixed.
Figure 15 shews the apparatus mounted in the hull of a vessel to serve for
propelling the same. In this case the suction pipe extends to the bow end and
the discharge pipe to the stern end of the vessel, the apparatus being driven by
any suitable engine. By arranging the propelling apparatus in this manner
within the hull of a vessel it is completely protected from liability to injury.
By means of a suitable valve the propeller may be instantly converted into a
bilge pump as in the double acting arrangement previously described.

Rotary Apparatus for Lifting, Forcing, and Mixing Liquids and for
Propelling Vessels.
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

page_text: is to be performed to be particularly described and ascertained in and by the
following statement:-
-
This invention relates to apparatus for lifting, forcing, and mixing liquids
and for the propulsion of vessels, and consists more particularly of a rotary double
or multiple acting apparatus in which two truncated hollow cones are mounted
on a common shaft with their larger or smaller ends facing each other and
revolve within a casing in such manner that by the rapid rotary motion of the
cones the liquid is drawn in at the smaller ends of the cones and discharged at the
larger ends. These hollow truncated cones may be provided with an internal
helicoidal partition, or preferably with a plane longitudinal partition so as to
permit of the apparatus rotating in both directions, said partition serving to
increase the output of the apparatus especially when the cones are driven at a
considerable speed.
The apparatus may also consist of a single cylindro-conical casing within
which rotates, as in a bearing, a body of similar form keyed upon a central
driving shaft carrying an exhausting and forcing screw of slow pitch. The
water which enters at the smaller end of the cone is drawn in by the rapid motion
of the central revolving body and is delivered at a height which depends upon
the velocity of rotation. Thus the product of the apparatus being a function
of the velocity it is always possible to obtain a very considerable outflow which
renders the apparatus especially suitable for use, for example, in raising a sunken
vessel, extracting the water from a flooded mine, etc.
The apparatus is adapted for raising water from wells and mines, for use in
civil and military engineering works, as a water engine for agricultural purposes,
and as a pump for decanting wines, etc. The apparatus is also adapted to serve
as an efficient propeller for vessels by drawing in water at the bow and expelling t
at the stern.
The invention is illustrated by way of example in the drawings accompanying
my Provisional Specification wherein Figure 1 is an elevation of the apparatus;
Figure 2 a longitudinal section, and Figure 3 a transverse section on line 1-2
Figure 2. Figures 4 and 5 shew modifications of the apparatus. Figures 6
and 7 shew the apparatus diagrammatically as applied to the propulsion of vessels.
In Figures 8 to 15 single acting apparatus based upon the same principle and
adapted for the same uses, are illustrated; Figure 8 is a vertical section of such
an apparatus, the same apparatus being shewn in Figure 9 as driven by a
dynamo-electric machine. In Figure 10 the apparatus is shewn as applied for
raising water from a well. Figure 11 is a side elevation and Figure 12 a front
elevation of the apparatus mounted on a tandem cycle for use as a fire engine
or pump; Figure 13 shews a portable hand-operated apparatus, and Figure 14
a modification of the latter arrangement, while in Figure 15 the apparatus is
shewn as applied to the propulsion of vessels. The same letters of reference
denote like parts in all the figures.
Referring to Figures 1 to 3 the apparatus consists essentially of two truncated
cones a mounted upon a common shaft with their larger ends facing one
another, the shaft being capable of revolving freely in end stuffing boxes cd.
Each of the truncated cones may, however, be replaced by a conoidal figure of
any form generated by the revolution of a rectilinear or of a curvilinear generatrix,
providing that the transverse area gradually increases from the point of admission
of the water to its point of delivery. The casing e is provided at each end with
a chamber with which a pipe f connects, while at the centre of the casing a
pipe connects with the space comprised between the cones a a the sectional
area of the pipe g being however at least equal to the sum of the areas of the
two pipes ff. In this example the pipes f f are the inlet pipes and the central
pipe is the delivery pipe. The chambers are of larger diameter than the
pipes in order to form a reservoir in front of each cone and facilitate the entry
of the liquid. The cones a are each provided with a tubular extension h which
revolves, as in a bearing, within the cylindrical part of casing e clearance

page_text: however being left between the casing and the surface of the cones. By this
construction back flow of the liquid towards the inlet and resistance to the efficient
working of the apparatus will be prevented but other means for attaining the
same end may be employed. The shaft extends beyond the ends of the casing
and is provided at one end (or at both cals) with a pulley driven by any
suitable motor. The chambers are preferably attached to the ends of the
casing e by flanges and bolts so that the direction of the pipes f may be varied
as desired, but they may be fixed in any other suitable manner. Similarly the
delivery pipe may be fixed to the casing or be mounted so as to be angularly
adjustable.
In order to increase the output of the apparatus each cone is provided with
an internal partition of helicoidal form or preferably disposed in one of the axial
planes of said come as shewn in Figure 3. This latter arrangement permits of
the apparatus being revolved in either direction and presents the advantage of
producing a very large output especially when the cones are driven at a very
high velocity.
In certain cases in order that the stream of liquid may be deprived of all
whirling movement and be consequently projected from the apparatus in an
absolutely straight line, the delivery pipe may have an internal partition g¹
dividing it into two equal parts as shewn in Figure 4.
The combination of these two truncated cones with their larger ends facing
each other so that the two jets of liquid become mixed on delivery, enables a very
large output to be obtained and one much greater than that which could be
obtained with two apparatus each containing a single truncated cone only. In
this apparatus the longitudinal thrusts on the shaft balance one another. This
is of the utmost importance in view of the great velocity at which the apparatus
revolves, especially as regards wear of the parts, for as the machine is constantly
balanced friction is reduced to a minimum.
Figure 5 shews a variation in which the smaller ends of the truncated cones a
are opposed to one another, the apparatus in this case having a single inlet y
and two delivery outlets f.
Figures 6 and 7 shew diagrammatically the application of the apparatus as
a propeller.
In Figure 6 the apparatus comprises two suction pipes f f and a single delivery
pipe g while in Figure 7 there is a single central suction pipe and two delivery
pipes, this latter arrangement enabling the vessel to be steered by varying the
outflow or by cutting off one delivery pipe by means of suitable valves. In both
cases the delivery pipe or pipes open at the stern, and the inlet pipe or pipes
at the bow, of the vessel either laterally or centrally as shewn. The delivery
pipes may be provided with a number of branches so as to obtain a series of jets
acting at different points simultaneously. The apparatus used for the propulsion
of vessels may also be used for preventing the vessel from sinking in consequence
of injury to the hull as by the employment of suitable valves the apparatus may be
immediately converted into a pump while still retaining its use as a propeller.
Any number of these apparatus may be employed in combination either mounted
upon a single shaft, the one behind the other or radiating from a centre.
The apparatus may be constructed with but a single truncated cone (see
Figure 8) in which case it comprises a casing e with an inlet f and a delivery 9.
The coned part e of the pump casing is provided at the inlet end with a short
cylindrical part i within which is fitted, as in a bearing, a tubular extension h
terminating in a truncated conical part a which is received within the casing e,
the necessary clearance being left between them as before.. The coned part a
is mounted centrally within the pump casing upon a tapered shaft b journalled
in stuffing boxes c d and carrying a helix 6' of slow pitch.
The shaft b may be extended at 62 and carry a driving pulley j as shewn in
Figures 13 and 14 or it may be coupled to the shaft of a dynamo or other
machine as in Figures 9 and 11. The chamber k may be angularly adjustable

page_text: с
as before described and the stuffing box c is provided with a thrust bearing m for
the shaft b.
Figure 10 shews the apparatus applied as a well pump comprising a post n
upon which are mounted winch handles op for driving the bevel gear wheel
and pinion keyed on the prolongation 62 of shaft b. s is the suction pipe which
extends down into the well and is provided with a valve for keeping the pump
primed and t.is the delivery pipe which extends upwards to any suitable point.
In Figures 11 and 12 the pump is shewn as mounted on a water tank v carried
by a tandem cycle u so as to serve as a fire-engine for example, the pump being
driven by a dynamo.
Figure 13 represents the apparatus arranged as a hand pump to be operated by
two crank handles w. The apparatus may be either permanently or temporarily
fixed or be transported by placing it upon a truck and fixed by means of a base
plate a.
Figure 14 shews the pump as mounted upon a pillar which also carries the
driving gear comprising a pair of crank handles w keyed on a shaft y mounted
in the pillar below the top upon which the pump is fixed.
Figure 15 shews the single cone form of apparatus in the hull of a vessel for
propelling the same. In this case the axis of the apparatus is shewn as being
vertical, the suction and discharge pipes opening at the bow and stern respectively
and the apparatus being driven by any suitable engine. By arranging the
propelling apparatus in this manner within the hull of a vessel it is completely
protected from liability to injury. By means of a suitable valve the propeller
may be instantly converted into a bilge pump as in the double acting arrange-
ment previously described..
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. A double or multiple rotary pump consisting essentially in the combina-
tion of a pair or pairs of hollow truncated cones oppositely mounted upon a
common shaft and revolving within a casing in such manner that by the rapid
rotary motion of the cones the liquid will be drawn in at their smaller, and
delivered at their larger, ends substantially as specified.
2nd. In an apparatus of the kind specified, the truncated cones provided with
an internal partition of helicoidal form or of flat form and disposed in one of
